Electronic Controller Operations
Introduction The chiller is fitted with a CAREL S4 Evo electronic controller, which is
visible on the unit cover and is housed inside the electronic controller box
assembly in front of the refrigeration unit.
The electronic controller controls and displays the chiller temperature, and
signals temperature alarms.
To ensure efficient operation, the electronic controller automatically forces a
defrost cycle when required.
The electronic controller is pre-programmed. SKOPE does not recommend
that settings be changed unless it is absolutely necessary.

SKOPE BackBar X
Running the Chiller
Operating
Modes The electronic controller runs the chiller in constant ‘Normal’ mode. The
BackBar X does not use an energy saving/night mode (or similar).
Note: Normal mode is suitable for perishable product (all shelves maintain
temperature below 5°C).
During some conditions or refrigeration system alarms, the electronic
controller may run the chiller in cold climate protection mode, or may shut
down the lights and/or refrigeration system. Refer to “Cold Climate
Protection” on page 14, or “Messages and Alarms” on page 13 for more
information.
Compressor
and Fans The compressor and condenser fan will start approximately just after the
chiller is turned on. The compressor will stop and the condenser fan will run
at low speed when the control probe temperature reading reaches 1°C
(parameter St). The compressor will start and the condenser fan will run at
full speed when the temperature reaches 3°C (parameter St + rd).
The evaporator fan starts approximately 3 seconds (parameter F0) after the
compressor and condenser fan. To verify, check that the FAN light is lit on
the electronic controller faceplate.
Temperature
Probes Three temperature probes feed data to the electronic controller: the control
probe, the evaporator probe, and the condenser probe.
The control probe monitors and controls the chiller temperature, provides
the chiller temperature for the electronic controller to display, and notifies the
electronic controller of any erratic or abnormal temperatures that could
identify an issue within the refrigeration system.
The evaporator probe controls the refrigeration system defrost initiation and
termination.
The condenser probe monitors the refrigeration system condenser
temperature and notifies the electronic controller of any abnormally high
temperatures that could identify an issue within the refrigeration system.
Defrost Cycle The defrost cycle will begin after 6 hours (parameter dl) of real time. During
the defrost cycle the compressor stops and the evaporator fan runs
continuously. The defrost cycle will terminate when the evaporator probe
reaches 4.5°C (parameter dt), or after the defrost cycle has been running for
45 minutes (parameter dP).
Lighting Press the Light button on the electronic controller faceplate to manually
switch the lights on and off.

Display Description
The chiller is in Normal mode and the electronic controller displays the
chiller temperature.
The chiller internal temperature is above 13°C.
The chiller is in Cold Climate Protection mode. The chiller enters Cold
Climate Protection mode if the control probe detects the interior
temperature below parameter St - CCt temperature for more than CCd
time. The lights remain on and cannot be switched off (see over page for
more information).

Cold Climate
Protection The chiller will enter cold climate protection (CCP) mode if the ambient
temperature becomes too cold. This happens if the control probe (at the
evaporator air out) detects the interior temperature below -1°C (parameter
St - CCt) for more than 30 minutes (parameter CCd). The lights will stay on
and cannot be switched off while the chiller is in CCP mode. The chiller will
return to Normal operation mode once the control probe reading raises to
parameter 1°C (parameter St) temperature.

Programming the Electronic Controller
The electronic controller parameter configuration program is set by SKOPE
at the factory. A label on the controller box indicates the parameter
configuration program number (e.g. the BackBar X Series use program 100
(integral) and 103 (remote).
The electronic controller parameters can be modified using the keypad.
Frequent parameters can be access and changed without entering a
password (e.g. temperature setpoint). Locked parameters are protected by
a password to prevent accidental or unauthorised modifications.
Temperature
Setpoint
The chiller temperature setpoint is factory set at 1.0°C for storage of
perishable products (all shelves maintain temperatures below 5°C). The
cabinet setpoint can be adjusted between 0°C and 3.5°C if required (see
over page).
SKOPE do not recommend that the setpoint be changed unless it is
absolutely necessary, and then only by small increments at a time.
To view and adjust the temperature setpoint
