SCCB TYPE G-202
GENERAL CHARACTERISTICS
NOTE: Due to the fact that this manual refers to two similar types of thermostats, the more developed G-202
thermostat will be referred to in further parts of this manual.
The self-contained control block, hereafter called G-202, constitutes a modern, convenient and easyto-use equipment and has been made using microprocessor techniques with the application of automatic
surface assembly process.
Owing to the twin part case and revolutionary technical design, the G-202 can be applied to any
refrigerated counters or refrigeration chambers. The safe voltage operated control panel (5 V) may be
installed in any place, without the necessity of cutting any additional openings or running a number of power
supply cables far away from the equipment being controlled.
The G-202 has been equipped with two temperature sensors, which provides for the capability of
connecting doors opening sensors to the control panel or to the actuating module, which are safe voltage
operated (5 V), as well as four outputs allowing direct connecting of the 230 V operated equipment, with
loading ability as summarized in table 1.
At the special request of the Customer, the G-202 may also be equipped with an additional
evaporator frosting detection system, connected to the thermostat, causing the unit to automatically enter the
defrosting mode.
If the G-202 is used in refrigeration chambers, it stabilizes the temperature, as well as controls
automatic defrosting, the period of which may be adjusted to specific surrounding parameters; it is also
equipped with a pushbutton for activating manual defrosting. As distinct from G-18-2, the G-202 has also
been equipped with lighting system switch over that operates independently of the main circuit breaker
(main isolator).
No special maintenance measures are required for these thermostats; the keyboard has been made
from the special kind of oil, high temperatures resistant as well as resistant to most chemicals. However,
cleaning this oil with sharp objects is not allowed. Instead, use the damp cloth and clean the front panel with
it from time to time.

DELIVERY, INSTALLATION AND HOOKUP
1. In the appropriate place within the unit cut a hole of 20x30mm in size, however if masking frame of
the panel is not used the size of the hole should be 58x109mm.
2. Mount the actuator on the rail and latch it. For store equipment the SCCB actuator module MUST
be fixed to the floor!!!
3. Any metal elements, through which the G-202 or its cables are run should be ground or protected
otherwise. Fitting G-202 to enable direct action of water on it (e.g. water condensating on the bottom
cover of the shop window), touching the outlet pipe from the evaporator etc. and changing
considerably its temperature in relation to the ambient temperature (e.g. fitting in the immediate
proximity of the compressor and its accessories, cooled and heated elements) is not allowed.
4. Cut the ribbon connecting the panel with the actuator into the desired length plus 2-3cm. Then, after
running it through all penetrations, cut it once more by cutting its ends at right-angle and clip the
plugs on it so that the end of the ribbon be hidden to approx. 0.5mm. The ribbon must be introduced
perpendicular to the plug and clipped so as to make its twisting or non-parallel layout impossible.
Connecting the ribbon to the connectors see figure at the end of the instructions.
5. After fastening the G-202, connect the power cables according to the description provided on the
actuator wall. Depending on the G-202 version some outputs may be not used - on the label with the
description they will not be described and the type symbol in the corresponding places will contain
zeroes - do not connect any conductors to these outputs!!!
6. The applied connectors are certified for continuous load of 16A!!! They incorporate fine thread and
special lamellae, which prevent the wires from being cut, therefore only light tightening ensures
maximum good contact and the use of greater force may lead to stripping out of the thread. In the
result this may lead to the socket melting and short-circuit !!!
7. Any cable surplus should be cut down or winded up and clamped using special plastic bands. The
cables must be firmly secured on its entire length and must not get in contact with the compressor
and its equipment
8. After connecting the unit to the power source there can be voltage across the lighting cable
regardless of switching on or off the unit with the button
therefore the starter or the
fluorescent lamp should be replaced only with the power cord disconnected from the plug!!!
THE SAME APPLIES WHEN CARRYING OUT ANY OTHER REPAIRS !!!
9. If heaters are used, their power must be fitted correctly, which means that during failure of the G-202
or of the external contactor and switching them on for good, there were no possibility of fire or the
device damage.

If great power heaters are used then the safety thermostat must be absolutely applied on the
evaporator. This thermostat must operate on the different principle, for instance: mechanical
thermostat.

VI.
THE PRINCIPLE FOR INSTALLATION OF SENSORS, TYPES OF
PROTECTIVE CASES
For each type of the manufactured equipment a place for securing the sensors and the SCCB settings
should be determined experimentally. Absolutely do not change the fastening location nor the way the
sensors are secured nor modify SCCB settings without prior carrying out new tests relating to
temperature stabilization and equipment defrosting cycle !!!
Fastening of the chamber sensor must be done in such a way so that it does not get in contact with food
products and is not exposed to damage when cleaning the equipment. The sensor can be fixed using a
special plastic bracket. This solution causes fast (on/off time delays see VI p. and 6 and 7) response of
the sensor and the entire thermostat to the change in the air temperature in the unit. When desired or
necessary to slow down and "smooth" the time of sensor response to the temperature changes we
recommend to fix it to the metal part of the unit.
Fasten the evaporator sensor in the way to ensure maximum and good contact with the evaporator
lamella and in place where ice remains for the longest time during defrosting. Its fastening should
prevent it from being pushed out by the growing ice. The sensors, wherever possible, should be fixed
vertically so that the cable exits from the bottom of the sensor.
Sensor cables can be shortened or extended in any way, however with respect to the following
rules:
- do not cut the sensor cable at a section smaller than 0.5 m. From the case
- it is not recommended to extend the sensor cable to more than 20 m.
- THE SENSOR CABLES CAN BE CONNECTED TO THE TERMINALS OF THE ACTUATOR
SENSORS IN ANY WAY!!!
(in the same way as you connect the plug to the ~230V outlet)
- for cable extension we recommend using OMY 2x0.5 mm type conductor
- connect the extended cables with great care, by soldering each pair of cores and put thermally
shrinkable jackets on them. Then apply water-proof silicone on the joint and clamp one more
thermally shrinkable jacket on it.
- whiten the ends of the conductors connected to SCCB with tin
OPERATION METHOD

Maintenance Manual for Manufacturers,
SCCB TYPE G-202
A - General Information
1. Having turned the equipment on, the three-second starting procedure is activated, during which the
display will show two dashes, for the period of two seconds, and then for the period of one second, the
version of the controller program will be displayed, as well as two to dashes. No activation of the
equipment under control takes place then.
2. Following the completion of the starting procedure, two horizontal dashes signalling the energizing
status will light up on the central segments of the display - if the unit has not been in “on” mode
before!!!. The unit will be activated after pressing the pushbutton
temperature value of the chamber sensor.
. The display will show the
3. Having pressed and held down the pushbutton
for the period of a half second, the display will start
blinking and showing the evaporator temperature, while after the consecutive five seconds, the G-202
will automatically re-enter the chamber temperature readout mode. Note!!! This function is also
activated during the defrosting time, when the display shows the „dF” symbol. The temperature of the
4.

7.
chamber sensor can also be seen by pressing
for 0,5 second, which will make the display show the
chamber temperature (without blinking) to automatically re-enter the displaying of the „dF” symbol
mode after the consecutive five seconds.
The compressor activation is signalled by the small red diode in the right, bottom corner of the display
showing the temperature. This allows easier check of possible damage and mall functions to the system.
If the compressor should have turned on, but the compressor has not been turned on due to the activation
of any of the protection systems (see points 6, 7, 10 and 11), the dot signalling the compressor's
operation will be blinking. When the protection system preset time preset elapses, the daughter will stop
blinking and will be lit permanently, while the compressor will be activated .
The delay in turning the compressor on after its activation temperature is reached (user set
temperature minus bottom value of the hysteresis) is equal to 30 seconds. If the temperature drops again
during this time. The condition of exceeding 30 seconds will be verified again. This is designed to
protect the compressor against unnecessary activation due to e.g. articles placement, droughts, etc.
After every reaching of the preset temperature (user set temperature minus bottom value of the
hysteresis), as well as following any power failure or voltage drops below 175 volts, the G-202 will
make impossible for the compressor to be activated for the period as specified by the ‘c2’ parameter. If,
however, ‘c2’=0min, the protection time will last 60 seconds following any power failure.
pushbutton, the 5-second delay will appear in the
8. Having turned the equipment on using the
compressor activation. This is to cancel the power failure protection from point 7 – this will also pertain
to the time specified by the ‘c2’ parameter, following the compressor’s prior deactivation. This allows
faster compressor operation check.
9. The controller has been equipped with alarm features, providing information regarding sensor’s damage.
Depending on the sensor(s)’ status, the controller performance will be different.
• The mall function to the chamber temperature sensor will make the display show the A1 symbol.
The controller will activate the compressor in the time cycle (clock-based control) in accordance
with times specified in ‘c8’ i ‘c9’ parameters. The defrosting process will function as usual.
• If the evaporator sensor is damaged, the display will show the A2 symbol. The manual and
automatic defrosting is blocked then!!! The only possibility of defrosting the unit is to press the
pushbutton
in order to turn off the unit, and then wait for the ice to thaw.
• If the sensors have been damaged, only the A1 symbol will be displayed.
Having repaired the chamber sensor, the A2 symbol will start to be displayed.
10. If the buzzer has been installed in the controller – see p. II, the buzzer will signal any pressing of any
button. If the controller is turned off (two horizontal dashes on the display are seen then), the buzzer will
signal only if the following pushbuttons are pressed, namely:
and

11. The lighting system activation and deactivation will take place after pressing the
pushbutton. This
will be signalled by the green LED. If the door opening is reason for lighting system activation, the
green LED will not light up.
The button
will operate independently of the thermostat current switch over -
.
B - Defrosting
1. If the necessity for the additional defrosting occurs, due to difficult operating conditions, press the
pushbutton. This will make the green LED light constantly on the
pushbutton, while the „dF” symbol
will appear on the display, rather than temperature measurement symbol, and this is where the unit will
enter the defrosting cycle.
2. If the defrosting occurs, and the temperature on the evaporator is higher than set in the ‘d2’ parameter,
the unit, after some 10 seconds, will enter the defrosting exiting mode, to resume the operation when the
said mode terminates.
3. If the defrosting occurs, and the temperature on the evaporator is lower than set in the ‘d2’ parameter, the
G-202 will activate the defrosting process, and after reaching the temperature as specified in the ‘d2’
parameter, the unit will enter the defrosting exiting mode (this status is signalled by the green LED,
which blinks on the
pushbutton). The heaters version will then enter the defrosting exiting mode,
comprising two consecutive Phases:
• Thawing Phase – where the compressor and fans are turned off for the period as specified by the‘c3’
parameter;
• Evaporator Freezing Phase – where only the compressor is operated, in order to lower the
temperature of the evaporator to the temperature as specified by the ‘c4’ parameter, prior to
reactivating the fans. The maximal freezing time can not be exceeded, regardless of whether the
evaporator has achieved the temperature of ‘d4’, specified by the ‘c4’ parameter.
4. The procedure of exiting the defrosting mode is terminated with the activation of fans, turning off the
5.
6.
7.
8.
„dF” symbol on the display and turning off the green LED blinking on the pushbutton
.
Should the fans be absent or not connected to the S.C.C.B. system, the unit will act as if they are
installed.
The defrosting process will be terminated following the achieving of the evaporator temperature as preset
in the ‘d2’ parameters, or if the time preset by the ‘c1’ parameter has been exceeded.
Having turned off the „dF” symbol and terminated the defrosting process, the display will show the
temperature as stored right before the defrosting commencement, for the period of time as specified by
the ‘c7’ parameter – this is intended for preventing claims with respect to “violent temperature
fluctuations in the unit”.
The unit performance is the same as in the case of manual and automatic defrosting.
C – The Door Opening Sensor Operation Principle
1. If the door has been opened, the fan will be stopped immediately. In addition to the above, depending on
the ‘r7’ parameter setting, the light may be turned on in the G-202 unit. The display shows the
temperature.
2. If the door has not been closed, after 30 seconds, the “dr” symbol will be constantly lit on the display. If
the buzzer is installed in the controller, the short lasting sound signal will be repeated every 30 seconds.
3. If the door continues to be open after the time as specified in the ‘r8’ parameter, the alarm will be
activated, which will be signalled by the display blinking with “dr” symbol, and with the sound signal if
the buzzer is installed. This is when the compressor will be turned off.
4. If the R8 = 0 the alarm will be activated immediately after opening the door.
5. The alarm may be silenced through pressing any pushbutton. Closing the door deactivates the alarm and
normal operation is resumed.

SCCB TYPE G-202
6. The controller allows connecting both the door opening mechanical sensor (R6=01), and the mechanical
or magnetic sensor, disconnected in the course of door opening (R6=02).
Hysteresis
When programming the‘d0’ i ‘d1’ parameters (the minimal and maximal user preset temperature) attention
should be paid to the fact that the ‘d3’ hysteresis value causes additional shifting of the temperature to
higher or lower values with relation to the user preset temperature level.
This is particularly significant with regard to the so-called “plus” equipment which should always be
operated at the temperatures above 0oC.
As the Manufacturer of the refrigeration unit (refrigerated counter) (temperatures above 0oC), we require the
unit to allow the operation within the temperature range that does not exceed the values specified below:
Deactivation min: 2ºC. Activation max: 10ºC
Symmetric hysteresis for ‘d3’ even values
Symmetric hysteresis for ‘d3’ odd values
Example No. 1.
The ‘d3’ hysteresis it set at, for example
2ºC
For this hysteresis value, the parameters should
be set as follows: ‘d0’ at 3ºC and‘d1’ at 9ºC
Example No. 2.
The ‘d3’ hysteresis it set at, for example
4ºC
For this hysteresis value, the parameters should
be set as follows: ‘d0’ at 4ºC and ‘d1’ at 8ºC
Example No. 3.
The ‘d3’ hysteresis it set at, for example
3ºC
For this hysteresis value, the parameters should
be set as follows: ‘d0’ at 3ºC and‘d1’ at 8ºC
Example No. 4.
The ‘d3’ hysteresis it set at, for example
5ºC
For this hysteresis value, the parameters should
be set as follows: ‘d0’ at 4ºC and ‘d1’ at 7ºC

VIII. SYSTEM PARAMETERS PROGRAMMING
Having activated and checked the unit operation (standard settings are factory set), start entering system
parameters to the G-202 unit.
For this purpose, turn off the unit by pressing the
pushbutton. Then press the buttons
and
,
depress and hold, at the same time press the
pushbutton. All the three pushbuttons need to be
depressed and held for at least the period of 3 seconds. If any of these buttons has been released during the
said time, the unit will abandon the programming mode. When the unit has assumed the programming mode,
the LEDs on the
and
pushbuttons will start to blink, while the display will show the ‘c0’ per one
second. Then, the value of this parameter most recently programmed will be shown. Enter the required
settings, using the
pushbuttons, any longer pushbutton holding time causing the data “fast
rewinding/forwarding”. Then press
, in order to approve the data entered and start entering the next
parameter.
Partial entering of the settings is also possible. If any alteration of the particular setting is not required,
simply press the
pushbutton and the G-202 unit will assume the next parameter setting mode.
Note !!!
The refrigeration unit Manufacturer may block access to a portion of or even to all
parameters available from the keyboard, by means of the computer programming unit. If
this is the case, and the alteration of any of the blocked parameters is attempted, the
display will show the ‘bL’ symbol for the period of 1 second.
Remarks on SCCB programming.
1. IT IS THE RESPONSIBILITY OF THE MANUFACTURER OF THE REFRIGERATING UNIT
AND THE SERVICE ENGINEER TO ENTER NEW SETTINGS REQUIRED FOR NORMAL
FUNCTIONING OF THE UNIT !!!
2. Do the programming carefully, preferably writing down earlier the values of the particular parameters on
a sheet of paper. Remember that any error made when programming some parameters will have very
serious consequences including damage of the product and the refrigerating unit.
3. Having programmed and started the unit check it for proper operation and recheck if the settings of the
system parameters are correct.
4. Transfer of the Service Instructions or any information regarding the mode of programming the SCCB
system parameters to the end user is absolutely not allowed. The end user should receive only and
exclusively a copy of the section IX of these instructions.

G-202 MAINTENANCE – USER PART
1. Having turned the equipment on, the display will show two dots, for the period of one second, and then
the version of the controller program will be displayed as well as dots for the period of one second.
Following the completion of the starting procedure, two horizontal dashes signaling the energizing
status will light up on the central segments of the display. The unit will be activated after pressing the
pushbutton
. The display will show the temperature value in the device (temperature readings
from the cold room sensor)
2. Setting of the user temperature of the stabilization in the counter.
•
To change settings press the
button. The LED green diode lights on the button and recently
entered value of the temperature is displayed.
•
Buttons:
are used to set the temperature. Each longer holding of the button causes faster
“changes” of the temperature settings.
•
After setting desired temperature one should press the
button again. After that the green LED
diode on the button will light off, and the G-202 will exit the programming mode and start operating
using a new program.
•
If the
button is not pressed the G-202 will automatically exit the programming mode after 5
seconds from the last button press. The temperature value will not be stored in that case.
3. Turning on/off the lighting system.
The lighting system activation and deactivation will take place after pressing the
will be signaled by the green LED diode. The button
current switch
pushbutton. This
operate independently from the thermostat
.
IMPORTANT !!!
. The green LED
If extra defrosting is necessary due to severe operating conditions then press button
will light up on the button, and "dF" will appear on the display instead of the temperature measurement
and the unit will enter the defrosting cycle.
Defrosting will end automatically after the preset time elapses or on reaching the factory preset
temperature.
Carrying out any repairs on one own causes loss of warranty and may bring to en electric
shock and other threat. Therefore all kinds of repairs should be carried out by authorized
and qualified personnel!!!

Check
Check:
- if 220V voltage is present on the power supply terminals L and N
- correct connection of the actuator to the control panel
- remove and reinsert the ribbon sockets
- connect another ribbon
2. The compressor Check:
will not start despite - 220V voltage presence on terminals K and N - If present, then check
its power-on
the compressor
signaling
- if not, then check correct connection of the actuator with the control
- red LED
panel
- connect another ribbon
3. Defrosting heater Check:
does not switch on - if there is voltage 230V on clamps as described on the casing of the
controller
- if there is, check the heater
- if not then check the connection of the executive module with a
control panel
- connect another ribbon
5. Wrong
Check:
temperature
- connections of the sensors to the connectors
indications
- value of the parameter ‘d4’
- correct fastening of the sensor
- condition of the sensor cable – the cable can not show any damages
- carefully the appearance of the external surface of the sensor case
for any signs of mechanical damages.
6. The desired
Check:
temperature cannot value of the parameter ‘d0’ and ‘d1’ (d0<d1)
be set
7. Blinking of dots
Check :
on the display,
- power supply voltage value
cannot be turned
- condition of the power supply connectors
off
- tightening of the power supply connectors
- correct connection of the actuator to the control panel
- connect another ribbon
8. ‘Abnormal’, Check:
