1. INTRODUCTION

The ERC 101 is a multi-purpose electronic parametric controller dedicated to a broad range of applications.

ERC 101 meets OEM requirements for timesaving and flexible production setup.

The latest generation CPU, plenty of memory and high-end electronic components allow for uniquely versatile application use. Three separate password-protected user levels can be used to control more than

100 different parameters to accommodate any individual customer’s requirements.

The IP-rated body, advanced materials and internationally approved hardware design make the ERC 101 ideal for use in almost any climate around the world, indoors as well as outdoors. Laboratory work is easy and flexible with the ERC 101. With a USB-powered gateway, Danfoss KoolProg software reduces time spent programming. On the OEM assembly line, just one docking station can easily program up to 1,000 controllers a day – at zero inventory cost.

One relay control features three inputs and is powered by a globally compatible, lightweight, switch mode power supply. All components have been carefully selected to help reduce the CO2 footprint. The power supply uses on average just 0.4W – 50% less than today’s average controller.

Power plug: for laboratory use, low quantity

OEM production or whenever spade connectors are not available.

Clips: are used to secure the ERC 101 in place in the case of rear mounting. They are not used with front mounting. There are two identical clips, one placed on either side of the ERC 101. See Chapter 4

– Mounting – for further details.

2.3 Connections

Programming an individual unit in a laboratory: the USB gateway requires KoolProg Software running on a PC. It enables parameters to be set in real time and an array of status information to be read (bidirectional connection). This method is used to determine the correct parameters during R&D.

Once the desired settings have been determined, a KoolProg ERC specific parameter file is saved to the

EKA183 USB copy key for later mass programming.

The USB Gateway is a laboratory tool, offering fast and easy programming of any ERC 101 controller.

KoolProg software installation is provided; the gateway is standard inventory for OEM labs.

Mass programming on an assembly line:

the docking station is used for high volume programming of ERC controllers, for example on an assembly line. The docking station is a write-only device.

See above (Programming an individual unit) for preparing the EKA183A USB copy key (code no.

080G9740), which is to be inserted into the docking station. The settings are then loaded into each successive controller in a matter of seconds.

KoolProg software is not required for mass programming.

Note:

please refer to the koolprog manual for more details about programming.

KoolProg: is the software from Danfoss for programming the ERC 101 via a USB cable and a PC rather than with the front panel buttons.

Please refer to the KoolProg manual for details.

3. OVERVIEW OF THE PRODUCT

The ERC 101 is a state-of-the-art, IP65 (front)-rated, multi-purpose electronic parametric controller for use in a variety of applications.

A single power relay (16A-rated) ERC 101 controls up to 2.5 HP compressors without auxiliary relay

(230V). The controller features unique algorithm for defrost control and compressor protection and is particularly well suited for use in areas with unreliable power supply and/or unstable voltage.

Together with the Danfoss docking station, programming of predetermined parameter sets can be achieved in just 10 seconds. There are over 100 parameters (see Section 7).

The ERC 101 can also be programmed via USB using the Danfoss KoolProg software, which means that the most suitable parameter findings can be located quickly during the application development process.

It is also possible to operate and program the controller using the control buttons (only when actually installed in a refrigerator / freezer).

3.1 Control buttons

The ERC 101 has four buttons (circled in image) on the front which can be programmed to perform different functions. See Chapter 6 – Configuration of inputs and outputs for detailed information.

3.2 Connector inputs

Connect up to three Danfoss original sensors according to your application needs.

There are two analogue inputs: S1and S2 ( a ).

Supported input options:

· Cabinet (air) temperature — analogue data [°C]

· Evaporator temperature — analogue data [°C]

· Condenser temperature — analogue data [°C]

· Digital input — binary data [on/off ]

There is one digital input: diC ( b ) for PC communication being used either with a door sensor or with the USB Gateway.

NOTE:

for detailed information refer to section 6.1.

The ambient light sensor can be used for determining shop open / closed times for economy mode switching, for determining the brightness of the LED display or both.

6. CONFIGURATION OF INPUTS AND OUTPUTS

The ERC 101 inputs and outputs are configurable by the customer. Before getting started it is a good idea to check if all inputs are configured correctly and match the sensors attached.

For instance: Danfoss supplies only 2-pole defrost sensors, so input S2 will most likely be used as a defrost / evaporator temperature sensor input.

Input and output configuration settings are part of the assignment menu (ASi).

Please contact your local Danfoss representative for information about default settings.

NOTE:

Coded sensors will impact on the number of possible configurations.

6.3 Set passwords

Password level 1 / PS1

Password Level 2 / PS2

Password Level 3 / PS3

These assign passwords to the three levels of access. The password is a three-digit number. Access levels are Shop, Service and OEM. You may not therefore have access to change all the passwords. Passwords are entered by using the up and down arrow buttons.

Danfoss advises against using passwords which are easy to remember or enter, for example 111, 222, 123 etc.

NOTE:

When accessing the controller with 3 wrong password in a sequence ERC will automatically block access for 15 minutes.

7. PARAMETERS

This chapter details all user-accessible parameters in ERC 101 software 5.05.

NOTE:

Incorrect parameter settings can lead to inadequate cooling, excessive energy consumption, unnecessary alarms and in the case of temperaturesensitive food storage, breaches in food hygiene principles and regulations. Only a trained operator should make changes to parameters.

INFO!

Some parameters may be hidden to you. When scrolling through menus, the parameters available will have been pre-determined using KoolProg software.

Your access level will determine which parameters you can view and edit.

The access level can be set separately for each parameter using KoolProg software. There are three levels of access – 1, 2 and 3. Level 1 is for shop access, level 2 for technicians and level 3 for OEMs. The access levels cannot be set using the buttons. Passwords for the different levels can however be altered for the level of access you have – for example a level 2 user can change the password for level 1 and level 2 but not level 3.

23

Set point / StP

StP is visible with KoolProg software only. This parameter defines the desired temperature (set point). In standard operation the set point is changed by simply pressing the “temperature up / down” buttons on ERC 101; for laboratory and assembly line you may opt for software controlled set point adjustment

(speed improvement)

Set point adjustment ratio / SPr

The default value is set to 0.5 and the parameter is hidden by default.

Spr defines the position of the setpoint in relation to cut-in and cut-out.

Spr = 0,5 sets the setpoint mid between cut-in and cut-out. Spr = 0 sets the setpoint at the cutout. Spr =1 sets the setpoint at cut-in.

Differential / diF

This defines the difference between the cut-out and the cut-in. The desired temperature is determined by SPr and diF.

High Set Point / HSE

Low Set Point / LSE

These parameters define the temperature range limit of the controller. Once set, the desired temperatue (setpoint) can not go above HSE or below LSE.

LSE Sets the minimum value for the set point

HSE Sets the maximum value for the set point

Cut-in and cut-out are automatically calculated from the desired setpoint (set bybuttons on the control) and the differential. By default, cut-out and cut-in are

0,5*DiF above or below the desired temperature.

Example: The desired average temperature in the cabinet is 5 degrees, and the differential is set to 2 degrees:

Air Temperature Adjustment / tAd

This parameter is a relative value and allows adjustment of the control sensor temperature.

For instance, at a measured temperature of 7*C and tAd set to -2K, the input from the control sensor will be 5*C instead.

High Temp Alarm / HAt

Low Temp Alarm / Lat

High temperature alarm and low temperature alarm allow for individual alarm setpoints. Both are absolute values. By setting HAt to the maximum value and LAt to the minimum value, alarms will be deactivated.

High Alarm Delay / Htd

Low Alarm Delay / Ltd

These parameters express the number of minutes to wait before sounding an alarm once the High/Low Temp Alarm temperature is reached. Immediately prior to the alarm sounding, another check of the temperature is made to see if the temperature is still in the alarm zone; if it is not, the then the alarm is not sounded.

In most situations, the Low Alarm Delay will be set to 0 to warn about too low a temperature immediately.

ERC 101 Reference manual – 7 PARAMETERS

25

Pulldown Delay / Pdd

Normally, it is not necessary or desirable to sound an alarm during a pull down

(the initial phase of reaching the desired temperature).

This parameter prevents the High Temp Alarm HAt sounding during pull down and after a defrost for the number of minutes set for the parameter.

NOTE:

It does not apply to the Low Temp Alarm LAt.

Alarm Buzzer Duration / Abd

The ERC 101 alarm sounds for 10 seconds, followed by silence for 50 seconds. One alarm sequence therefore lasts 60 seconds. These values cannot be changed. This parameter determines how long in minutes an audible alarm will continue while there is still a reason to have an alarm. If set to 999, the alarm will continue to sound until the reason for the alarm is cleared – for example the temperature has dropped enough or the door closed. In some cases, it may be necessary for a user or technician to take action in order to clear the alarm. If set to 0, the alarm will never sound.

Auto Clear of Alarm / Error / ACA

If this parameter is set to nO:

The alarm status will not disappear automatically even if the condition which caused the alarm is no longer valid or present. If set to yES:

As soon as the condition which caused the alarm is no longer valid or present, the alarm status will automatically change back to inactive. There will be no trace of the alarm having occurred.

In general, Glass Door Merchandise applications will be set to yES and Commercial

Fridges and Freezers set to nO. For example, if the temperature goes too high for a period there may be food safety considerations in a freezer containing food but not in a fridge with cold drinks.

ERC 101 Reference manual – 7 PARAMETERS

27

Minimum Run Time / Crt

This parameter is a number of minutes from 0 to 30.

It determines the minimum number of minutes the compressor must run before a

Temperature cut-out can take effect. For example, if the temperature sensor indicated that the cut-out temperature has been reached, but the number of minutes set in this parameter have not elapsed since the compressor last started, then the compressor will continue. It will only stop once the duration given by Crt has been reached – provided the temperature is still low enough.

Crt thus overrides the cut-out.

Minimum Stop Time / CSt

This parameter is a number of minutes from 0 to 30.

It determines the minimum number of minutes the compressor must remain idle before a Temperature cut-in can take effect. For example, if the temperature sensor indicates that the cut-in temperature has been reached, but the number of minutes set in this parameter have not elapsed since the compressor last stopped, then the compressor will stay off. It will only start once the duration given by CSt has been reached – provided the temperature is still high enough.

CSt thus overrides the cut-in.

Maximum Off Time / Cot

This is the maximum time in minutes the compressor is allowed to idle – up to 480 minutes. Cot is set to zero by default (inactive). If ERC 101 is to be used on a draft beer (ice bank) application, this parameter can be used to control the ice thickness.

Error Run Time / Ert

Error Stop Time / ESt

These two parameters only become active in the unlikely event of a broken temperature sensor. They are then used to run the application in safety mode. At the same time the sensor error will be shown in the display.

Ert and ESt values are based on OEM experience and are by default inactive.

Ert and ESt define the duration the compressor will run (Ert) and be idle (ESt).

Example: Ert = 4 [min] and ESt = 16 [min] will provide an average cooling system activity of 20%.

Minimum cut-in voltage / uLi

Minimum cut-out voltage / uLo

Maximum voltage / uHi

These three parameters provide voltage protection to the compressor. Start by setting uHi, followed by uLo and uLi.

uLi: When the compressor is due to start, the voltage of the power supply will be checked and the compressor will only be allowed to start if it is at least the value given in this parameter.

28

ERC 101 Reference manual – 7 PARAMETERS

uLo: When the compressor is running, it will be switched off if the voltage goes below that given in this parameter.

uHi: When the compressor is running, it will be switched off if the voltage exceeds that given in this parameter. If the compressor is already stopped, it will remain switched off.

Power On Delay / Pod

This is the delay in seconds between power-on and the compressor being activated.

Depends on the Power on Temperature setting as explained below.

Power Factor / PFA

This value is hidden by default. The parameter is used by the Zero Cross function to optimize the switching position of the relay contact.

Warning:

Do not change without first consulting your local

Danfoss representative.

Initial Cut In / iCi

If the control temperature is between cut-in and cut-out at power up customers can determine if the compressor shall start immediatly (yes) or wait for cut-in temperature to start (no).

Power on Temperature / PoT

This parameter is used to accelerate the first application test on the OEM assembly line; if the cabinet temperature is higher than this parameter the Power On Delay is overruled and the outputs are activated without delay.

ERC 101 Reference manual – 7 PARAMETERS

Defrost Type / dFt

When set to nO, the defrost function is disabled and no automatic defrosting will occur.

When set to EL or nAt, electrical, natural or off-cycle defrosting is used. An additional setting of Hgd (hot gas defrosting) is available.

Terminate Temperature / dtt

This parameter defines at what temperature the defrost cycle will stop.

The temperature is given by the evaporator sensor or by the cabinet temperature sensor if no evaporator sensor is used.

Tadd defrost reset temp / drt

The defrost counter is saved and restored at power-up, but if the temperature sensor, used for defrost, is higher than this value at power-up, it is assumed that the evaporator is free of ice and the defrost counter will be cleared.

Minimum Interval / dii

This parameter can be set to between 0 and 96 hours and defines the minimum time period between the start of two defrost cycles. Once the minimum interval has expired, the defrost cycle will start at the following cut-out or once the maximum interval dAi has been reached.

Maximum Interval / dAi

This parameter can be set to between 0 and 96 hours and defines the maximum time period between the start of two defrost cycles.

Minimum Time / dit

This parameter can be set to between 0 and 240 hours and defines the minimum duration of a defrost cycle. During this period, the ERC 101 will not check the temperature. Once the minimum time has expired, the temperature will be checked and if the Terminate Temperature dtt has been reached, the defrost cycle will end.

If dtt has not been reached, defrost will continue until either dtt is reached or the

Maximum Time dAt reached, whichever occurs first.

Maximum Time / dAt

This parameter can be set to between 0 and 240 minutes and defines the maximum duration of a defrost cycle.

The ERC 101 will not allow a maximum time to be entered which is less than the minimum time, or a minimum time which is more than the maximum time.

ERC 101 Reference manual – 7 PARAMETERS

31

Initial Defrost Interval / idi

This parameter defines defrost behaviour after power-on. It can be set to between

0 and 96 hours and determines when the first defrost cycle will start after powerup. Setting this parameter to a low value will force a defrost cycle to start earlier, for example for testing purposes. The timer monitoring the defrost interval will not be reset by a subsequent loss of power, but it will continue to count once power is restored.

Initial defrost duration / idd

The “initial defrost” functionality is being used for factory testing for acceleration measures. This featured may not be desired under normal operation, you may decide to deactivate this function by setting a maximum number of compressor cycles (0 — 999).

0: idi always off

1-998:number of cycles before deactivation 999: idi always on

Defrost On Compressor Time / dCt

If this parameter is set to yES, then defrost cycles are based on the total time the compressor has been running.

If this parameter is set to nO, then defrost cycles are related to elapsed time, regardless of how long and how often the compressor has been on.

Pull Down Initiate Temperature / Pit

This parameter indicates the temperature which causes a pull down to start. If the temperature measured inside the cabinet exceeds this value for longer than one hour, then pull down will start. The compressor will have already cut-in, so the only effect is to stop defrost cycles until the desired temperature is reached. The period of one hour is fixed and cannot be altered.

ERC 101 Reference manual – 7 PARAMETERS

33

Pull Down Cycling / PCy

This is the duration in minutes of the compressor cycling at the reduced set point temperature. Once the desired Pull Down Limit Temperature PLt has been reached during Pulldown, the compressor will continue to cycle on / off for the duration of

PCy. At the end of the period defined by PCy, the Set Point temperature will return to normal and Pulldown will cease.

Pull Down Defrost Interval / Pdi

Even though most applications do not need Defrost during Pull Down, an extended defrost during pull down can be applied. This is the time between defrost cycles during Pull Down. It is measured in hours and can be up to 48 hours.

During Pull

Down, this setting overrides the Defrost Interval and Defrost Time settings (see the

Defrost section).

Pull Down Duration / Pdd

You can choose to limit the maximum Pull Down time. Once this time value

(max. 48 hours) is reached, Pull Down will stop regardless of whether the desired pull-down temperature has been reached.

Pull Down Limit Temperature / PLt

This parameter sets the minimum allowed temperature during pull-down,

In order to protect valuable contents you must always specify the absolute minimum temperature allowed in your application.

For Glass Door Merchandisers 0°C/32°F protects bottles from freezing; for Commercial Fridges you may opt for a slightly higher temperature (e.g. 2°C)

Pull Down Reduction Temperature ∆t / Prt

ERC 101 calculates a lower set-point during Pull Down mode to increase the cooling capacity of your appliance.

For each hour the cabinet temperature is above the

Pull down initiate temperature, the set-point is reduced with the value of Prt.

This section deals with parameters for the display.

NOTE:

Some display parameters can be set in such as way that they may be illegal in some jurisdictions. Please check local legislation.

36

ERC 101 Reference manual – 7 PARAMETERS

Display Unit / CFu

This parameter sets the display to Fahrenheit or Celsius. Switching from one to the other will cause all temperature settings to be automatically updated accordingly.

Display Resolution / rES

This parameter can be set to 0.1, 0.5 or 1 and affects the way the temperature is displayed. With the parameter set to 1, the display will only ever show temperatures rounded to the nearest whole degree. At 0.5, it will round the temperature to the nearest half degree for display.

For example, 3.3 degrees will be shown in the display as 3.5 degrees and 3.9 as 4.0.

With the parameter set to 0.1, no rounding occurs.

This parameter does not affect the temperature itself, merely the display.

Display Range Limit / rLT

In some Point of Sales applications you may want to show the desired instead of the real temperature. This parameter sets whether the displayed temperature is the actual temperature or whether it is restricted to the cut-in / cut-out limits. Set to nO means that the actual temperature will de displayed.

The parameter is set to nO by default.

Display Delay/ ddL

In order to provide a realistic temperature appearance for an application, a display delay can be set.

The parameter sets the time constant τ (tau) of the moving average filter for the display.

Physically, one time constant represents the time it takes the system’s step-response to reach 66% of its final value and five time-constants the time it takes to reach 99% of its final value.

The parameter can be set from 0 to 10 minutes.

ERC 101 Reference manual – 7 PARAMETERS

37

Display Offset / doF

This parameter is a relative value and allows the temperature displayed to be different to the temperature measured. For instance, at a measured temperature of 7°C and doF set to -2K, the displayed temperature will be 5°C instead.

Lock Time After Defrost / dLt

In order not to show a rising temperature during defrosting, the displayed temperature is locked at the temperature shown at the start of the defrost cycle for the number of minutes set in this parameter.

0 = no lock.

Show Pull down state / SSC

If set to yES, this parameter causes the display to show SC when the system is in

Pull Down mode.

If set to nO, the temperature continues to be displayed.

Show Defrost / SdF

If set to yES, this parameter causes the display to show DEF when the system is in defrost mode. If set to nO, the temperature continues to be displayed.

Display Intensity / din

ERC 101 can have its display intensity (brightness) set. This requires that buttons are configured accordingly.

APPENDIX V: APPLICATION SPECIFICATON

V.1 Control sensor

The control sensor must always be connected and is used for controlling the cut-in and cut-out of the compressor according to the set-point. The sensor is also used for the displayed temperature.

Placement of sensor:

Vertical coolers with fan

Most common placement is in the return air to the evaporator. The sensor can be placed close to the fan – even when the fan is pulsed during compressor off periods: The updating of the temperature is blocked when the fan is stopped and only updated when the fan has been running for a while, so that the heat from the fan does not affect the temperature reading.

For applications sensitive to sub-zero temperatures, sensor placement in the evaporator outlet air can be considered.

Vertical freezers with fan

Placement in the return air or in the freezer compartment

Coolers without fan

the best results are normally obtained when the sensor is placed at the side-wall, 10 cm from the back and approximately at 1/3 from the bottom or where the evaporator ends.

The control sensor must always be connected and is used for controlling the cut-in and cut-out of the compressor according to the set-point. The sensor is also used for the displayed temperature.

50

ERC 101 Reference manual – APPENDIX V: APPLICATION SPECIFICATION

V.2 Evaporator sensor

The evaporator sensor is only used for de-icing of the evaporator and has no control purpose.

Placement of sensor:

Place the sensor where the ice melts last.

Please be aware of that sharp finns can damage the cable.

V.3 Condenser sensor

The condenser sensor is used to protect the compressor against high pressure when the condenser is blocked or the condenser fan fails.

Placement of sensor:

Place the sensor at the liquid side of the condenser.

Use a metal bracket or metal tape to ensure good thermal conductivity. Be sure that the cable does not pass hot spots at the compressor or condenser that exceeds 80°C.
