The main functions of the SLV compressor are:
⋅⋅ Motor control for the energy-optimised variable speed brushless DC motor used in the Secop SLV
compressor
⋅⋅ Management of minimum and maximum run times
⋅⋅ Condenser and compressor fan control
⋅⋅ Temperature measurement and algorithms for determining the temperatures in the cooling application
⋅⋅ PI control to determine the required cooling capacity
⋅⋅ Display control (optional)
⋅⋅ Control menus to change the operating status or set parameters
⋅⋅ Alarm system reporting faults on the display, with a buzzer, via the Modbus interface, or via the alarm
relay
⋅⋅ Data logging system to store events in the memory of the control unit. Data logs can be read via the
system bus
⋅⋅ Hot gas defrost system
⋅⋅ Cold storage fan control module
⋅⋅ Modbus communication for supermarket monitoring systems
The controller also features integrated monitoring of the operating conditions and takes corrective action
to prevent any damage to the electronics, which may occur in the event of an overload.
The following monitoring functions ensure that operating conditions remain within the acceptable range:
⋅⋅ Temperature sensor on the printed circuit boards to monitor the temperature of the electronics in the
enclosure.
⋅⋅ Temperature sensor to monitor temperature in the motor inverter.
⋅⋅ Monitoring for correct motor speed; motor speeds outside the permissible range can damage the
valves and bearings.
⋅⋅ Inadequate line voltage due to fluctuations in the line supply.
⋅⋅ Locked rotor caused by excessive pressure.

2.2
Connect Cables
The maximum cable length should not exceed 3 metres for all internal and external applications. A cable
length of more than 3m could alter the EMI performance. In this case, the customer must make application
specific inquiries to determine requirements for the certification of cooling applications. Under normal
circumstances the supply line and the communication lines are longer; it is recommended to follow the
installation guideline for the Modbus.
All protective earth lines, PE, in the application must be collected to one star point. This prevents loop
currents which could cause problems concerning the electronic components, communication lines and
sensors. The star-point is normally a screwed terminal on the chassis.
The compressor must be connected directly to PE; due to the low voltage decree. The PE connection by the
motor cable shield has a more functional cause and is not sufficient as a safety relevant connection, so in
case of an error it is not able to carry the whole current.
The cable shield of the motor cable must have a low impedance connection to the compressor. The connection
should be made to the compressor where the shield has a large surface area. The newer compressors will
come with a clamp instead of a plug for the shield.
Signal and data lines can be put together but divided from the 230 Vac power lines, including those lines
which are switched by the internal relays.
The relay switched lines may be put together with the supply line as long as the other lines are not
carrying current disturbances. The preferred way of installation heavily relies on the switched loads. In
case of doubt the lines should be installed separately; to avoid coupling of disturbance between the lines.
Connecting the Modbus communication line between two devices when the cable is installed outside the
building or between two buildings is not allowed. This prevents potential induction problems, in case of
lightning.

Operations
The different parameters of the SLV controller can be accessed via the local display or via the Modbus. In
this section, only the local display interface will be described.
The display CRA 172 performs the following functions:
Daily operation of the cooling appliance, readout of measurements and status of the refrigeration system,
actual temperature, alarms, defrost activation, stop mode, setting of parameters, reset of alarms and
more.
By entering the correct access code, it’s also possible to get into the service level of the controller.
Besides the numeric display, there are 4 additional LED’s which show the status of Alarm, Defrosting,
Service and Cooling.
To access the different parameters of the SLV controller for the local display interface, there are three
different access levels. Each level can be protected with an individual access code, defined by the
manufacturer of the cooling appliance. If a level is protected with an access code, this code must be
entered first.
If the SLV controller is accessed via both the CRA 172 and the Modbus at the same time, the latest
modified value for a setting will be stored as the final.

Description of Functions
4.1
Application selector
4.1.1 Purpose
Many light commercial cooling applications are supposed to cool a variety of goods.
The cooling of different types of goods requires specific temperature settings and functions of defrosting,
fan control etc. These settings are considered to be application dependent.
The selection of the application can be done by the end user, timer based or pre defined from the factory.
4.1.2 Functional description
Using the application selector, it is possible to select up to five different sets of settings which provide the
SLV controller with different functions or simply different temperature settings.
The selection of the actual application can be done by the daily user via the local operation display, the
internal control timer, digital input or as a factory selection at the OEM.
In the parameter overview the default settings for all parameters are shown for each of the five possible
applications. Furthermore, the overview indicates whether a setting can be set differently for each of
the five applications or if this setting is one common setting for all applications. If different settings are
possible in the particular applications, this is indicated with an “x” in the column “Multi apps”
Before an application can be selected, this application must be enabled.
Application selection by the daily user:
If more than one application is enabled, the daily user can select one of the enabled applications by
pressing the middle button on the display. If more than two applications are enabled, repeatedly pressing
the middle button switches between the applications.
If the digital input DI1 is configured for application change over, the predefined application will be selected,
as soon as the DI1 is closed. As soon as the DI1 is disconnected, the selection of application depends on
the remaining settings.
If automatic application change over is desired, this can be achieved by using the control timer to select
another application during the active timer. As an alternative, it is possible to force each application into
another application, as long as the controller is in night mode.
4.1.3 Restrictions
For all the settings which can be programmed differently in the five applications, this is only made possible
if the application has first been selected. This means that each application has to be programmed
separately, by enabling and selecting the application prior to the programming.
4.1.4 Dependencies
None
13
4.2
Modbus Addressing
4.2.1 Purpose
The SLV controller can be mounted in a Modbus network of up to 247 controllers. To recognize the different
controllers on the network, each controller must have its own, unique address.
4.2.2 Functional description
The Modbus address can be set either via the T4C service tool or the local display CRA 172. If the
controller has a password, this must be entered first.
The address range can be set in the range from 1 to 247. Parameter 'Modbus address' (o03).
4.2.3 Restrictions
If the Modbus address is modified via the T4C, the user must ensure that the new address is within the
setting range of the T4C, otherwise the communication to the controller will be lost, until the correct
address range has been selected on T4C and the network has been scanned again.
4.2.4 Dependencies
None
14
4.3
Temperature
acquisition
4.3.1 Purpose
The temperature acquisition system handles all the temperature measuring related issues, such as
sensor selection, weighting of sensors and sensor error detection.
4.3.2 Functional description
The SLV controller has 5 sensor inputs. The S3, S3b, S4 and S5 sensors are compatible with the 5K NTC
sensors. The S6 sensor uses a Pt1000 sensor.
Important remark: The sensor inputs are not galvanic separated and the sensor inputs are connected
directly to the mains supply! For that reason only double isolated sensors must be used.
Weighting of sensors
In some cases it might be necessary to use 2 sensors, to achieve the correct temperature measurement. For
measuring the cabinet temperature, the sensors S3 & S4 can be used, or a mix of these. Furthermore, it’s
possible to use different weighting of the 2 sensors during the day and night time. The parameters “S3/S4.
Weighting for Tact at day” (r15) and “S3/S4 Weighting for Tact at night” (r61) give the weighting for day and
night respectively. If set to 100% only the sensor S4 is used. If set to zero, only the S3 sensor is used.
In the same way, it’s possible to weight the S3/S4 sensor for the alarm thermostat, ”Weighting for alarm
thermostat S4” (A36) and for the internal parameter “S3/S4” (U98), which amongst others can be used as
input for the read out on the display.
15
4.3
Temperature
acquisition
(continued)
Offset adjustment of temperature measurements
To compensate for measuring errors or wrong placement of the sensor, all sensors include an offset
adjustment. With the parameter “Sx offset” (r09), (r10), (r55), (r56) and (r57) it is possible to adjust the
respective temperature measurements from -10 to 10 K.
Filtering of temperature measurements
Furthermore all temperature measurements can be filtered with the parameter “Filter constant for
Txx”(o90 to o96)), which can be used for very unstable or fluctuating temperatures.
0:No damping, (fastest updating of the read out)
1: 0,10 K/sec
2: 0,09 K/sec
3: 0,08 K/sec
4: 0,07 K/sec
5: 0,06 K/sec
6: 0,05 K/sec
7: 0,04 K/sec
8: 0,03 K/sec
9: 0,02 K/sec
10: 0,01 K/sec (slowest updating of the read out)
Read out on the display
It’s possible to select between a variety of different parameters to be shown on the CRA 172 display,
“Display temperature” (099).
With “Minimum limitation of Display read out” (r06) the minimum read out can be limited downwards.
Furthermore, it’s possible to select, whether the temperature read out on the display must be in °C or °F.
The parameter “Temperature unit” (r05) is default set to °C.
Restrictions
All sensor inputs include a detection of open or shorted sensors. A sensor alarm will only be reported and
sent out if the sensor is being used by a function. If a sensor fails the sensor readout will be set to -300 °C
for an open circuit and +300 °C for a shorted sensor.
If the sensors S3/S4 are used in a weighted combination and one of the sensors fails, the sensor without
failure will be used and the weighting is disabled.
An alarm will be sent out for the defective sensor.
4.3.3 Dependencies
The step resolution for the display will be defined by the parameter “Display temperature step resolution”
(o15). See chapter for “Local display indication and menu structure”
16
4.4
Temperature logger
4.4.1 Purpose
The SLV controller has an internal temperature logger, which can log a predefined temperature directly
into the memory of the SLV controller. It is possible to attach an alarm to the logger, which will warn when
the upper or lower alarm limits are exceeded and when the alarm delay timer has elapsed.
4.4.2 Functional description
Using the parameter “Selection of sensor for the logger function” (h11), it is possible to select a
temperature sensor or an internal temperature calculation for the temperature logger. If no sensor is
selected, the logger will not begin. The speed of logging is determined by “Log interval” (h01). The number
of logs is limited to 1000. This means that the duration of the logging period depends on the number of
logs. For logging duration, please see the following table.
Logging interval
Maximum log duration in hours
Maximum log duration in days
15 minutes
250
10 days
30 minutes
500
20 days
60 minutes
1000
40 days
As soon as the logger is full, the oldest logs will be deleted and overwritten with a new log.
To limit at a certain number of logs, it is possible to set up thresholds for the logging range.
Logging of temperatures outside a predefined range:
If the “High Threshold” (h02) is set higher than the “Low Threshold” (h03), only temperatures outside
these limits will be logged.
Logging of temperatures inside a predefined range:
If the “Low Threshold” (h03) is set higher than the “High Threshold” (h02), only temperatures inside these
limits will be logged.
If the “Low Threshold for logging” and “High Threshold for logging” are set equal, no logging will be
performed.
Furthermore the temperature logger contains a separate high alarm function (h12) with adjustable alarm
delay (h13)
4.3.3 Restrictions
The maximum number of logs is limited to 1000.
In the event of a sensor error on the selected temperature probe, there will be no logging, but a sensor
error alarm will be generated.
4.4.4 Dependencies
None
17
4.5
Temperature alarms
4.5.1 Purpose
The SLV controller contains a temperature monitoring function, which will generate temperature alarms,
depending on if the temperature has exceeded some predefined limits. For some of the alarms a delay
timer can be set up.
4.5.2 Functional description
For the temperature alarm function, it is possible to use a different weighting of the temperature sensors
S3 and S4, compared to the one for the control thermostat (A36). This measurement will be compared
with the High and Low alarm limits. If the limits are exceeded, a delay timer will begin. The controller
has two different alarm delays, depending on whether the controller is in normal running mode (A03) or is
starting up after the initial start, end of defrosting or case cleaning etc (A12).
An alarm will be generated after the delay timer has elapsed. Depending on the settings for the Alarm
Handler, chapter 4.22, an alarm will be shown on the local display, or the local alarm relay will be
activated.
4.5.3 Restrictions
None
4.5.4 Dependencies
In case of a sensor error the temperature monitoring will stop and a sensor error will be sent out. If the
alarm thermostat is only using S3 or S4, the sensor error monitoring is only enabled for the active sensor.
18
4.6
Reference for the
capacity controller
4.6.1 Purpose
The purpose of the reference function is to generate a reference for the compressor capacity controller
and to create the limits for the temperature setting range during the day and night time. Based on the
deviation between the actual temperature Tact , compared to the temperature reference Tref, the capacity
controller will increase or decrease the requested compressor capacity. The bigger the deviation, the
faster the requested compressor capacity will be adapted.
As an option, the reference can also be obtained by using the digital input DI1 as an analogue input.
4.6.2 Functional description
Measurement and calculation of actual cabinet temperature Tact
The cabinet temperature can be measured with either S3, S4 or in special applications as a weighted
combination of both. In the event of wrong temperature measurements, due to wrong placement of the
sensors, both temperature inputs include an offset adjustment possibility. “Offset calibration of the S4
sensor” (r09) and “Offset calibration of the S3 sensor” (r10).
For the cabinet temperature measurement, with S3 and S4, a weighting of these 2 sensors is
implemented. The weighting can be different for the day and night time. “S3/S4 weighting for Tact at day
(100%=S4, 0%=S3)” (r15) and “S3/S4 weighting for Tact at night (100%=S4, 0%=S3)” (r61).
If the weighting is set to 100%, the temperature acquisition module only uses the S4 sensor. If set to 0%,
only the S3 sensor is used. If set to 50%, a 50/50 mix is used etc.
Calculation of Tref
The temperature reference Tref for calculating the reference for the PID controller is calculated as follows:
Tref = Tset + “Night setback” (r13)
The setting range of Tset can be limited with the 2 parameters “T set max” (r02) and “T set min” (r03)
To avoid a temperature reference too high or too low, the allowed temperature reference band is limited
with the following 2 set points:
“Tref min “(r25) and “Tref max.”(r26)
Besides this limitation of the temperature reference, the actual temperature Tact is calculated on
temperature measurements of S3 (U12) and S4 (U16). Both measurements can be offset adjusted (r10 and
r09), before a weighting is performed. This weighting can be different during the day and the night time
(r61 and r15). Finally a filtering of the calculated value can be performed, to avoid fluctuations of the Tact.
(O90)
Reference via external signal???
Description of parameter (r98), GIO Setpoint reference, is missing
4.6.3 Restrictions
None
4.6.4 Dependencies
If a weighted sensor signal for the Tact is chosen and one of the sensors S3 or S4 is detected to be
defective, a sensor error for that sensor will be generated. For the calculation of Tact the contribution from
this sensor will be ignored and the Tact will only be based upon the remaining functioning sensor.
19
4.7
Compressor capacity
control
4.7.1 Purpose
The purpose of this function is to calculate the requested compressor capacity, which is needed to cool
down or maintain the correct cabinet temperature during normal temperature control.
During the pull up/down of the cabinet, after the initial start or after a defrosting sequence, the capacity
controller will be over ruled by predefined capacity requests.
4.7.2 Functional description
The reference “T ref” for the controller is given by the reference function, based upon either the
temperature sensor S3, S4 or a mix of both. The ratio between them is set by the setting “S4 weight %”.
100 % means sole usage of S4 while 0% means solely S3 etc.
The determination of the actual requested compressor capacity is based on a PI controller, which
compares the actual temperature with the reference temperature. The bigger the deviation of the
temperature, the faster the adaptation of the compressor capacity is performed.
The SLV compressor can be speed controlled in the range from 50% to 100%, corresponding to 2000 to
4000 revolutions per min. If the requested compressor capacity is less than 50%, the compressor will start
and stop at 2000 rev-1 on a PWM basis. As default, the “Compressor Period time” (g05) is set to 15 minutes.
This means that the compressor will be running for a shorter or longer time within this period.

The capacity controller contains compressor protection settings to prevent the start/stop of the
compressors from occuring too often (g02, g03 and g04).
After initial start the compressor capacity will be set to 100%, until the reference temperature Tref has
been reached. In some applications it might be an advantage to run the compressor at the pull down
capacity for some extra time. Although the air temperature in the cabinet has reached the set point, the
goods will still be too warm. For that reason, the pull down period can be extended, until the “Tact below
Tref to end Pull Down” (n48) has been reached. After this the PI controller will be preset to a default value,
depending on whether the controller is in day or night mode (n53 and n54).
Depending on the size of the deviation between the reference temperature Tref and the actual
temperature, the requested capacity will now be increased or decreased faster or slower. The speed of
adapting the requested capacity depends on the settings for the PI controller.
Due to different load profiles for the different applications, the controller has a “smart setting for PI
control” (n30) application. The default setting is medium control, but if a faster adaptation of the requested
compressor capacity is needed, this can be changed to fast or even very fast control. On the other hand,
this can also be set to slow or very slow, if the cooling application requests this. In situations, where one
of these settings is not suitable for the application, the PI settings can be adjusted by the customer (n35
to n43). It is recommended to contact the supplier of the controller for optimal adjustment. Although, the
right smart setting or individual adaptation of the PI controller has been chosen, it might happen from
time to time, that the cabinet temperature exceeds a pre defined minimum or maximum limit, compared
to the temperature reference Tref.
As soon as the temperature reaches the limit of “Tact above Tref to start Pull Down limit” (n47) or the limit
of “Tact below Tref to start Pull up limit” (n46), a timer “Temperature out of range timeout” (n50) begins.
After this timer has elapsed, a forced Pull up or Pull down starts. The timer will be reset, as soon as the
temperature is back within the min and max limits.
If a pull down is requested, the compressor capacity will be preset to "Optimised pull down capacity" (n52).
This capacity will be applied, until the time "Optimised pull down time" (n51) has elapsed. Hereafter the
compressor will run at 100%, until the setpoint has been reached.
If a forced pull up has been initiated, the compressor will stop, until the temperature exceeds “Tact above
Tref to end Pull up” (n49).
If the digital input DI1 is defined to be used as a door switch, it is possible to stop the evaporator fan during
open doors. It is also possible to override the capacity controller at the same time. The compressor can be
stopped “Compressor Capacity switching on door open” (n22) or the compressor capacity can be preset by
“Compressor Capacity at door open” (n23). As soon as the door is shut again, the capacity controller will
resume with the same capacity as prior to the door opening.

4.7.3 Restrictions
Defrosting:
The PI controller is suspended during a defrosting sequence. Prior to a defrosting, the actual requested
compressor capacity is stored in the memory. After the end of defrosting and following pull down of
the temperature to a set point, the normal capacity control is resumed, based upon the previous stored
capacity.
Emergency cooling:
In the event of sensor errors, the capacity controller stops and the compressor capacity is preset to a
customer specified value, “Emergency cooling Capacity during S3 / S4 error” (n21). For more information
see the chapter “Emergency cooling”
4.7.4 Dependencies
The compressor capacity control can be overridden by an analogue signal on the DI depending on that the
parameter “I/O function” (o02) is set to 16.
A 500 kΩ logarithmic potentiometer connected to pin 31 and pin 33 is now representing a requested
compressor capacity between 0% and 100%.
All remaining control functions are not affeted by this!

4.8
Safety function
4.8.1 Purpose
The purpose of the “safety function” is to stop the compressor, if the pull down after a defrosting fails, due
to an open hot gas valve.
4.8.2 Functional description
The safety function monitors a predefined temperature after a defrosting sequence. The temperature
is selected with the parameter “Check temperature” (P50). If the compressor is running and the hot
gas valve is closed properly, this temperature is expected to be below the “Maximum Check value”
(P50), within a predefined time, “Time after compressor start to check” (P51). If this isn’t the case, the
compressor will stop and an alarm generated.

Emergency cooling
function
4.9.1 Purpose
The purpose of this function is to ensure a reasonable level of refrigeration in case of a reference
temperature sensor error.
For low temperature applications, it is better to run at a high compressor capacity while high temperature
applications prefer a reduced capacity, to prevent freezing of the chilled gds.
4.9.2 Functional description
If the sensor required by the application input setup is in a sensor error state, an emergency cling function
takes over and presets the requested compressor capacity to “Emergency cling capacity during S3 / S4
error” (n21). The emergency cling function takes over the normal capacity control, while all remaining
functions will run unaffected.
When normal compressor capacity control resumes, the PI controller will be “released” from the
emergency cling level and the requested compressor capacity will adapt to the actual needed capacity,
4.9.3 Restrictions
The function is overruled by the main switch off, service mode, case clean mode, loading of cabinet,
dr function cut out or the defrost mode, which do not contribute to the calculation of the requested
compressor capacity.
4.9.4 Dependencies
If a weighting of S3 and S4 is to be used for the input to the temperature reference, the emergency cooling
function will only be enabled when both sensors are detected to be defective. If only 1 sensor is defective,
the calculation of the cabinet temperature will be based upon the remaining sensor.

Defrost control
function
4.10.1 Purpose
The purpose of the defrost control function is to manage all aspects related to the defrosting of the
appliance. The start of the defrosting can be based on an internal real time clock, remotely controlled or
manually initiated by the end user.
4.10.2 Functional requirement description
Depending on the chosen cooling application, different defrosting sequences apply. In the following a
“worst case scenario” for a defrosting sequence is described. Depending on the different defrosting
modes, some of the functions can or will be omitted. Through settings, the user can choose between
Passive, Electrical or Hot gas defrost. The setting, “Defrost stop Sensor” (d10), allows the customer to
define, which temperature sensor must be used for termination of the defrosting on temperature. When
no sensor is chosen, the defrosting will only be terminated on time and the mentioned safety function
below will be disabled.

defrosting terminates with the timer only.
6. Before starting the compressor for new “Pull down”, the evaporator fan, if mounted, remains stopped
for a preset time, to drain the evaporator. “Drip off time” (d06). During drip off, the “Compressor

has elapsed, the compressor is released for a new pull down. The fan remains stopped for another
preset time, “Additional delay for evaporator fan start after drip off” (d07), to “tie” water drips to the
evaporator. In some cases it might be desired to control the starting point according to the evaporator
temperature only. In such cases the “Additional delay for evaporator fan start after drip off” (d07)
must be set to a very high temperature, so that the start is controlled according to the evaporator

4.10.2.4 Defrosting start
The SLV controller includes a real time clock and a defrosting schedule which can start the defrosting. It is
possible to set up a defrosting schedule on a daily or weekly basis. “Number of defrosts” (d90).
0 =Never, No automatic defrost,
Only manual or remote defrost start is possible.
1 =One pr. Day, based on the real time clock
The start time for each day in hours, (d71) to (d77) and minutes, (d81) to (d87)
2 =Multiple defrost per day at fixed hour, based on the real time clock
The SLV controller can initiate up to 8 defrosts per day. The first to last daily defrost start time in hours,
(d71) to (d77) and minutes, (d81) to (d87)
3 =Multiple per day, timer based with fixed interval, set via d03.
Every time a defrosting has been performed, a new defrosting will be initiated with a fixed interval after
the termination of the previous one.
4 =Defrost on demand
Interval between defrost, when multiple defrost per day has been chosen. (d90 = 3)
To prevent defrosts from occurring too often, the parameter “Min interval between defrost” (d62) can
be set in the range of 0 to 168 hours. This protection timer can only be reset by switching OFF and ON
the mains supply to the controller. The controller must be de energized, until the light in the display is
switched off!
Apart from the defrosting schedule, it is also possible to start and stop a defrosting either locally on the
control display “Allow local display to start defrost” (d61) or remotely via the Modbus, “Allow remote start
of defrost” (d60)
4.10.2.5 Drain heater
The drain heat output is intended for the connection of an optional, electrical drain heater. The function of
this heater is to prevent the draining pipes for the melted ice from sticking up, before and during defrost.
This function will most likely not be used on cooling applications (plus temperatures) but occasionally on
freezing applications. The relay will only be activated in connection with a defrosting sequence, the rest of
the time, it will be OFF. Please see the defrosting sequence.
4.10.2.6 Coordinated Defrosting
If the SLV controller and compressor are used in a cabinet together with another SLV set, on 1 common
cooling cabinet, it will be necessary to coordinate the defrosting. This secures that both cooling circuits
have terminated the defrosting, before a new pull down is performed on 1 cooling circuit, while the other
one still is defrosting. Otherwise there will be a high risk of ice build up on the cold evaporator, while the
second one is still defrosting. The maximum delay of a new started pull down after defrost is set with “Max
hold time after coordinated defrost” (o16). After this timer has elapsed, the cooling will restart and an
alarm “A05 Max hold after defrost exceeded“ will be sent out.
The coordination of this defrosting must be controlled via the Master on the Modbus.
4.10.3 Restrictions
⋅⋅ A new defrost is not initiated if the compressor isn’t running, due to a compressor error prior to a new
defrost sequence, in order to prevent heating of the cabinet.
⋅⋅ If a sensor error is detected on the defrost stop sensor, prior to start of defrost, the next defrost will be
started and terminated on time. A sensor error alarm is generated.
⋅⋅ If the defrost stop sensor is detected as faulty during the defrosting, the ongoing defrost is terminated
on time and a sensor error alarm is generated.
⋅⋅ If the temperature is not below the “check temperature” (P50) before the timer “Time after compressor
start to check” (P51) has elapsed, an alarm is sent out and the compressor and evaporator fan stop.
⋅⋅ The sensor error detection functionality on the “Defrost stop sensor” (d10) is only enabled when a
sensor is selected.
4.10.4 Dependencies
The coordinated defrost function will only work, if a master is present on the Modbus!.

4.11
Melt function
4.11.1 Purpose
On high temperature cabinets, there is a risk of ice flakes forming on the evaporator which could block
the air flow, when the thermostat has not made cut out for a certain time period. In order to avoid this, the
melt function will initiate a forced stop of the compressor with regular time intervals.
During the stop period the ice flakes will be transformed into solid ice and therefore prevent the air
passage through the evaporator from blocking up.
During the melting, the display will show the “DeF” code.
4.11.2 Functional description
The melt function is divided into two parts.
⋅⋅ The melting part, where the compressor stops and the evaporator fan, if present, continues to run. The
stop period is determined with “Duration of melt period” (r17).
⋅⋅ The cool down period, where the compressor is running at 100%, until the temperature set point has
been reached. After this the capacity controller resumes with the same compressor capacity as before
the start of a melting cycle.
The condition to start a melt period is as follows:
⋅⋅ The melting interval “Time between melt periods “(r16) is set different to zero.
⋅⋅ The compressor has been running continuously during the melting interval.
⋅⋅ The sensor for Tact has been without fault
⋅⋅ The Tact (U17) is between the lower limit “Lower temperature limit to start melt“(r19) and the upper
limit “Higher temperature limit to start melt “(r20).
⋅⋅ The temperature controller must be in range at this time
During the melting and cooling action, the following conditions must terminate the sequence:
⋅⋅ the sensor for Tact has a fault
⋅⋅ the melt function is overruled by an operation mode with a higher priority
⋅⋅ the Tact (U17) is not between the lower limit (r19) and the upper limit (r20)
⋅⋅ The melting interval (r16) is set to zero.
4.11.3 Restrictions
The melt function is inactive if “Time between melt periods” (r16) = 0 or “Duration of melt period” (17) = 0.
At thermostat air sensor error, the melt function is inactive.
Furthermore the function will be inactive, when “The air” (u17) is above the “High Lim air” (a13) or when
the SLV is in Pull down mode.
4.11.4 Dependencies
This function only makes sense on applications running with evaporator fans.

Case cleaning
function
4.12.1 Purpose
The purpose of the case cleaning function is to assist the daily user in the cleaning of the cabinet. If the
function is enabled, the daily user can initiate and terminate a case cleaning by pushing a button on the
cabinet.
4.12.2 Functional description
If the DI1 is defined to be used for case cleaning, the following sequence will start, as soon as the button is
activated:
First activation:
⋅⋅ The actual compressor capacity is stored in the SLV memory, to be resumed at the end of the cleaning
sequence.
⋅⋅ De icing of the evaporator starts. Depending on the setting of the “De icing method” (o47), this can
either:
1: Stop the compressor and the evaporator fan (if present) continues to run, until the defrost stop temperature has been reached.
2: Start a defrosting sequence, until the defrost stop temperature has been reached. This can be electrical, hot gas or natural.
At the end of manual cleaning, the daily user activates the button a second time.
Second activation:
⋅⋅ A new pull down of the cabinet temperature is initiated, until the set point has been reached.
⋅⋅ Normal temperature control resumes with the same compressor capacity as before the start of a
cleaning sequence.
The parameter “Case cleaning status” displays the status of the sequence:
0:No cleaning initiated
1: De icing of the evaporator is in progress. This can be either electrical, natural or hot gas defrosting.
2: Waiting for the daily user, to finish the cleaning and to activate the button a second time.
Display readout:
Readout on the display during the cleaning cycle and after following pull down: “deF”
Alarm handling:
During case cleaning all alarm messages are disabled (except for the case cleaning message and sensor
errors). The alarm delay for High Temperature alarms is set by the parameter “Delay timer for High
temperature alarms, after initial start up or defrosting” (A12).
Defrost:
A normal defrost sequence cannot be started, and an ongoing defrost will stop during case cleaning.
Stop of case cleaning:
The user can stop a case cleaning procedure using the same signals as for initiation. A case cleaning
procedure can also be terminated by setting the main switch to OFF.

control
4.13.1 Purpose
The purpose of this function is to control the condenser fan during the different running conditions and
different SLV states. Depending on the application, this fan can be a combined condenser and compressor
compartment fan or a dedicated condenser fan.
4.13.2 Functional requirement description
Before using the condenser fan control block, one of the relay outputs must be defined to be used as a
condenser fan relay. “Relay x configuration” (L01 to L059) must be set to 5. The condenser fan can be
controlled in four different ways, determined by the parameter “Condenser fan mode” (F11).
0: No control at all, always OFF
1: The fan runs continuously, as long as the compressor is running
2: Hysteretic control of the fan, based upon temperature measurement with S3b. Cut in temperature is
set with “Condenser fan start temperature” (F12). Cut out temperature is set with “Condenser fan stop
temperature” (F13).
3: Always ON, unless in stopped mode.
In some applications, it might be an advantage to pulse the fan during the night condition, to save further
energy or to reduce the noise emission to the surroundings. The function is enabled with “Condenser fan
pulsing” (F15). If set to ON, the fans will be pulsed during the night. The pulsing period time is set with
“Condenser Fan period time for pulse mode” (F16), while the “Condenser Fan On-time in % of period time”
(F17) is giving the duty cycle during pulsing.
Besides the above mentioned functions, it is possible to set up an alarm thermostat “Condenser Fan
Alarm temperature (S3b)” (F14) for monitoring the maximum temperature, in case of a blocked condenser
fan or dirt on the condenser surface.
If the temperature limit has been exceeded, an alarm A37 will be sent out.

Evaporator fan
Control
4.14.1 Purpose
The purpose of the evaporator fan control is to establish the necessary airflow through the evaporator and
to distribute the air into the cooling application. In applications with skin evaporators, running on fresh
meat applications etc, this fan may be used internally in the cabinet, to improve the cooling inside of the
cabinet. On passive or natural defrosting, the fan is also used to circulate the necessary airflow during the
defrosting.
4.14.2 Functional description
The mounting of an evaporator fan is optional for many of the SLV applications. For applications with skin
evaporators it is most likely that the fan will not be mounted. On the other hand, in most cases the finned
evaporators will need the fan.
Before using the evaporator fan control block, one of the relay outputs must be defined to be used as an
evaporator fan relay. “Relay x configuration” (L01 to L059) must be set to 6.
The parameter “Evaporator Fan mode” (F01) makes it possible to select the most appropriate evaporator
fan control mode.
0 =No evaporator fan control.
The relay output can be used for other purposes,
1= Fan control is enabled.
The fan will run during the different control states, over ruled by the defrosting, the door control and
compressor state. For details see parameter F03 to F07
2 =The fan control is enabled, with temperature check.
Same function as for 1, but with a safety function, which will stop the fan if the evaporator temperature
exceeds the safety level “Evaporator Fan stop temperature” (f04). The fan will start again, when the
evaporator temperature 2 K is below the safety limit again. The evaporator temperature is measured
with the same sensor as for the defrost stop function. Parameter “Defrost stop sensor” (d10).
During cooling (when the compressor is running) the fan must run, but during thermostat cut out (or PWM
control of the compressor) the fans can be pulse controlled, to save energy. The parameter “Evaporator
Fan mode” (F01) must be set different to 0 (enabled).
If the Digital input is defined as a door switch, it is possible to stop the evaporator fan during door opening.
The compressor capacity during open doors is set in the compressor capacity section. The parameter
“Evaporator fan stop on door open” (F03) must be set to 1 (enabled). If set to 0, the fan will continue
running at open doors.
During defrosting, the evaporator fan control is over ridden by the defrost sequence controller. On cabinets
with night set back, the fans can be pulsed at thermostat cut out in order to save energy.
When the cabinet is set to “cleaning mode”, the status of the fans depends on the cleaning routine.
“Evaporator Fan mode” (F01) must be set to 1.
Fan pulsing control
Function
Via the set point “Evaporator fan pulsing” (F05) it is possible to select how to control the fan:
⋅⋅ “Evaporator fan pulsing” (F05) = 0:
No fan pulsing – fan is always running, unless in stopped mode, cleaning mode or defrosting etc.
⋅⋅ “Evaporator fan pulsing” (F05) = 1:
Fan always runs together with the compressor, but will be pulsed at thermostat cut out
⋅⋅ “Evaporator fan pulsing” (F05) = 2:
Fan always runs together with the compressor, but will be pulsed at thermostat cut out, during night
condition or night blinds activated.
⋅⋅ “Evaporator fan pulsing” (F05) = 3:
The fan is always pulsed during night condition.

(continued)
If pulsing is active, the fan is pulsed according to a duty cycle pattern. Within a duty cycle the fan is set
to ON for a set period of time (set in percent of the duty cycle time) “Evaporator fan period time for pulse
mode” (F06).
The minimum duration of the time period must be adapted according to the type of output used to control
the fan (on relay outputs the lifetime has to be taken into account).
Each period starts with an ON period followed by an OFF period.
The output ‘Relay’ is ON during the ‘ON period’ and OFF during the ‘OFF period’.
4.14.3 Restrictions
When the compressor is not running, due to a compressor error, the evaporator fan will stop, to prevent
heating of the cabinet and unnecessary cold dissipation.

Blind control
function
4.15.1 Purpose
The purpose of the blind control function is to manage the blinds in front of the cabinet in sync with the
day / night mode of the controller. The function can be over ridden by the digital input, which will put the
curtain into day position at closed DI.
4.15.2 Functional description
The relay for the blind control will be engaged during night mode. For some control systems, a 1 pole
change over relay will be needed, to run the curtain motor in 2 different ways. This option is possible on
relay 4 and 5. To activate the blind function, the parameter “Blind function” (o62) must be set ON.
The SLV can be set into night mode via one of the following methods:
⋅⋅ Manually via settings in the controller
⋅⋅ Via a signal on the digital input, if the DI is defined for Day / Night control
⋅⋅ Via the “Day / Night function” in the Master Control system.

Light control function
4.16.1 Purpose
The purpose of the light control function is to manage the lights in the cabinet.
4.16.2 Functional description
The relay output for Light / Curtains is a 1 pole change over relay. The relay is engaged during night mode.
The SLV can be set to night mode via one of the following methods:
⋅⋅ Manually via settings in the controller
⋅⋅ Via a signal on the digital input, depending on settings in the controller
⋅⋅ Via the “Day / Night function” in the Master Control system.
4.16.3 Restrictions
Safety functions during day / night control:
When the night setting signal is lost, the controller will revert back to the default day condition. For that
reason, the night signal from the front end must be retransmitted (Master control block) to keep the night
mode in the SLV. Otherwise the SLV goes into day mode (light on and curtain up)

Real Time Clock and
control timer
4.17.1 Purpose
The SLV controller contains a real time clock with battery backup. This RTC is used for the control timer,
which can operate different functions. Furthermore the RTC is used for the defrosting schedule. For
defrosting, please see section 1.11 Defrost control function.
4.17.2 Functional description
The real time clock is powered from the internal SLV supply. In case of a power drop out, the RTC will be
powered from the internal battery back up.
The RTC can be set up in one of the following ways via the local display, the T4C or remotely via the Front
end system. If the set up is done via the local display, please follow the instructions in section 1.25, Local
Display indications and menu.
When T4C is used for setting up the RTC, you don’t have to enter a value for each RTC parameter. Instead
it’s possible to push the “Set PC time to SLV” in the T4C menu structure.
Based on the RTC, the SLV controller also has a control timer, with a daily schedule.
With this control timer, it is possible to intervene into the normal control of the SLV. The parameter
“Control timer Function” (t84) has the following options:
0 =None. No override of the SLV
1 =Do not use
2 =Stop mode. The SLV is put into the Stop mode as long as the Control Timer is active..
3 =Night operation. Selection of day / night mode via the internal control timer
4 =Light. Light ON / OFF as function of the control timer.
5 =Application changeover. Selection of an application as a function of a pre defined schedule in the
control timer.

The DI1 input holds many functions. The parameter “I/O function” (o02) specifies the usage of the DI
inputs. Depending on the DI type/function configured, the DI may operate either as a contact or as a push
button.
The status of the digital input is defined as follows:
⋅⋅ The contact is closed; the DI input is defined to be 1/ON
⋅⋅ The contact is open; the DI input is defined to be 0/OFF
Important remark: The Digital input is not galvanic separated and the input is connected directly to the
mains supply! For that reason, only double isolated switches must be used, as well as the cables must
fulfil the the double insulation requirements
If the DI1 is configured for alarm monitoring, an alarm will be sent out after the delay timer “Alarm delay
for DI1” (A27) has elapsed.

Storing and restoring
to factory settings
2.24.1 Purpose
The SLV controller contains a “Store to factory” and “Restore to factory” function. With this function it is
very convenient for the OEM to program the SLV with his own factory settings. Furthermore, it helps the
service engineer to restore a controller of cooling application in case of “lost overview” during modification
or optimization of setting on site.
2.24.2 Functional description
Storing settings as factory settings “Store to factory setting”(P31) is only possible with an OEM log in, the
restoring function “Restore to factory settings” (P30) is also enabled for the service engineer.
2.24.3 Restrictions
When activating the “Restore to factory” function, all actual settings in the SLV controller will be over
written immediately.
2.24.4 Dependencies

keeping the evaporator cold.
For hot gas defrosting it must be considered
to set the capacity between 50 and 100%, not
to loose the high condensing pressure.

Modbus
The Modbus used in the SLV is based on a RS-485 physical layer. Timing is controlled by an UART. The
transmission of data happens on a differential pair of wires. D1 is the non inverted representative of the
UART signal; D0 is the inverted signal of the UART.
Be aware: the RS-485 is not comparable with a RS-232. Both lines on a RS-485 are carrying the same
data, however on a RS-232 one line is for transmission and one is for receiving. The logic is based on the
voltage level, D0 > D1 = ‘1‘and D0 < D1 =‘0‘. Both lines are referring against each other, whereas RS-232
signals are always referring to GND.
The communication is controlled by a bus-master. The required supported bus speeds are 9.6 kbit and the
standard bit rate19.2 kbit; other standard bit rates are not supported.
Short description of all bus parts:
Knots
Knots are all devices on a bus which can receive and/or transmit data.
Bus-Master (Head-Unit, Gateway)
The bus-master is an active knot which starts the communication process requesting data from other
passive knots. There is always only one bus master allowed.
Secondarys
Secondarys like the SLVs are passive knots which should only transmit data when a master requests them.
A PNU list containing the data addresses is necessary to setup the bus-master.
Data-Line
The data-line in a RS-485 based Modbus is a differential pair. A differential pair is built by 2 wires; D1
and D0. The logic is based on the voltage level, D0 > D1 = ‘1‘and D0 < D1 =‘0‘. The differential pair should
always be together in a twisted pair.
For a minimum setup a bus-master, a secondary and the data-line between them is necessary. All the
following items are recommended; they will increase the performance and reliability significantly.
Common-Line
The common-line is required to bring all transceivers to one potential level.
BIAS-Resistors (RBIAS) (also called balancing or polarization)
The voltage level on the bus line is not defined when there is no transceiver active, so it is necessary to
pull D1 and D0 to the bus-idle-state (D1=‘1‘, D0=‘0‘).
Termination-Resistor (RT)
Must be installed at each end of the bus. They have to suppress reflections of the data signal at the end of
the data-line.
Shield
The cable which is used should be shielded to protect the data-line against outside disturbances.
Equivalent Circuit diagram of the Modbus

Modbus
(continued)
Recommended electrical equipment:
The SLV is designed to use standard network equipment with RJ-45 CAT5 cables and RJ-45 Y-distributors
with 1:1 pin connection. Make sure that the adapter is a shielded type; otherwise the shield will end behind
the first Y-connector. With these parts it is very simple to build up the connections between the SLV and
the bus master. Screw terminals and D-shell 9 are also accepted by the standard and could be used, the
SLV is designed to support RJ-45.
Be aware: Connection of a crossed cable in a 2-wire Modbus system may cause damage.
Installation:
Cable length
With the recommended usage of RJ-45 and CAT-5 cables, a maximum cable length of 600m may be
reached without additional equipment. A cable length of 1000m is possible when choosing other cables,
but this solution is normally much more expensive in material and installation. The possible cable length
depends on the installation quality and the type of termination.
Knot count
The knot count depends on the properties of each connected knot and from the quality of the installation.
At least 32 knots are always guaranteed (without repeater) by the specification, but this requires a proper
installation.
The properties of the knots are defined by their driver capabilities. There are “full”, “1/2”, “1/4” and “1/8”
available on the market. Full transceivers make 32 knots possible. With “1/2” transceivers up to 64 knots
are possible and so on. The weakest transceiver holds the maximum possible knot count. When there
is only one “full” transceiver in a bunch of “1/4” transceivers the bus is limited to max 32 units. With
“1/8” transceivers it is possible to build a network with up to 256 knots, but this requires good network
equipment and a very proper installation. With more than 32 knots a repeater could be necessary. When
more than 31 SLVs are used, a repeater is recommended.
Data-Rate
The SLV is supporting a data rate of 9.6 kbit and 19.2 kbit, 19.2 kbit being the default. Further data-rates
are not supported.
Wiring
The wiring is a one to one connection of the used lines, so all D1-lines are connected to one wire, similarly
D0- lines and all commons (see also “Pin-Assignments”). D1 and D0 must be together in a twisted pair.
This is guaranteed with the recommended equipment. The recommended topology is the “bus”- structure
with passive taps and a derivation cable to the SLV. The standard allows a maximum length for passive
taps of 20m and with multi-port taps of 40m, but the derivation cables should be as short as possible to
reduce problems and increase performance.
This solution is the simplest way to install a cheap network with low risk of error. The recommended
equipment is the standard parts for computer networks.
Polarization
The communication with the SLVs requires line polarization, the SLV as a passive device isn‘t prepared to
do this. Both bus lines must be pulled to a stable state which represent its logical idle state D1 = ‘1‘(type
5V) and D0= ‘0‘(COM/PE). The specification requires a value of 450Ω to 650Ω for each. These balancing
resistors must only be installed once on the bus. Often the master will have these resistors built in;
otherwise it should be close to the master.
Termination
The specification requires a resistor of 150Ω (0.5W) at either end or a 120Ω (0.25W) resistor with a 1nF
(25V) capacitor in series between D1 and D0. The bus termination is a very important point when the
knot count is high and/or the cable is very long. The termination must be placed on both ends of the
communication line.
It is possible that other Modbus equipment has built in termination, these terminators must be disabled
(these additional terminators will increase the busload and limit the possible length of the bus and knot
count). Only the terminators at the ends of the Modbus are allowed. The general rule is to reduce the
resistance or to decrease the current. A reduction of the current by using a RC-terminator instead of
a simple resistor is one of the safest ways. Be aware, it‘s possible that the terminations inside the bus
master only have a resistor. In these cases it is recommended to disable the internal termination and add
a RC-terminator external. This solution has the benefit of the lowest power consumption in bus idle state.
A bus configuration with a normal resistor termination should only be used if there are only a few knots
and a relative short bus.

Common-Line
The common-line is required to bring together all transceivers which are connected to the bus. This line
should have only one direct connection to PE, which should be close to the bus master. In some cases the
master has a common port which has a direct PE connection. If this internal PE connection is optional
a direct connection to a PE-rail would be the better choice. Further PE connections (like contact to the
chase of the fridge) will establish loops which could have influence on the communication quality. Non
isolated bus-knots are in general not allowed.
Shield
The used cables must be shielded. The requirements are the same as for the common. The shield must
be connected to PE at only one point. Best-case would be the same point as the common (when common
is direct connected to PE), but the common and the shield should have no further connection to each
other. A connection to PE via a pigtail will decrease the performance; a metal cable clamp on a PE-rail is
the preferable solution. All cables and connectors should be shielded. The shield of the female connector
must be connected to the other female connectors in the Y-adaptors or in the D-shells.
Pin assignments
If an RJ-45 or a 9-pin D-shell connector is used for a standard Modbus device, the pin outs hereafter must
be respected for every implemented circuit.

The following systems can be connected to the Modbus:
⋅⋅ ADAP-KOOL® – Danfoss supermarket monitoring system
⋅⋅
Master functions:
- Night offset
- Blind
- Clock synchronization
- Alarm limit offset
- Dew point control
⋅⋅ TOOL4COOL® – Secop tool for adjusting and servicing of variable speed compressor products
The possibility of errors in the installation is very limited when using standard computer network
equipment for the Modbus. A safely running bus is ensured with BIAS-resistors (inside the bus-masters)
and the correct termination. Bigger networks require a proper installation of common lines and shielded
cables.
