1Servicing Hydrocarbon
Overview
This cooler utilises hydrocarbon (HC) R600a as its refrigerant. R600a is a
natural refrigerant that has a very low environmental impact.
Special service requirements are needed as R600a is a flammable
refrigerant.
Safety hazards
The main R600a safety hazards are:
Flammable refrigerant.
Venting of R600a and compressor oil.
Asphyxiation.
SKOPE does NOT recommend performing hazardous activities on the
refrigeration system.

Service Manual
3Electronic Controller
Electronic Controller Operations
Introduction The SC112N-A chiller is fitted with a CAREL S4 electronic controller. The
electronic controller is visible on the front panel and is housed inside the
controller box at the front of the refrigeration system.
The electronic controller controls and displays the chiller temperature and
signals temperature alarms. It uses two temperature probes within the
refrigeration system to collect data and runs the chiller accordingly.
The electronic controller is pre-programmed; SKOPE does not recommend
that the settings be changed unless it is absolutely necessary. To ensure
efficient operation, the electronic controller automatically forces a defrost
cycle when required.
Faceplate Because the electronic controller plays such an important role, it’s helpful to
know the parts of the faceplate you may use.
IMPORTANT
The electronic controller must only be adjusted by an authorised
service agent.

Service Manual
Running the Chiller
Operating
Modes The electronic controller will automatically switch the chiller between
‘Normal’ and ‘Energy Saving’ modes depending on usage. If the front door
(electronic controller side) is not opened for four hours, the chiller will
automatically enter Energy Saving mode and the sign and interior lights will
switch off. To manually switch the chiller between Normal and Energy
Saving modes, press and hold the Energy Save (up) button on the electronic
controller faceplate. The chiller can also be bought into ‘Day’ mode by
opening the front door (electronic controller side).
Compressor The compressor cycles on and off during Normal and Energy Saving modes.
It does not run when the chiller is in defrost mode. If the electronic controller
displays ‘Err’ there is a fault within the refrigeration system and the
compressor will not run.
Evaporator
Fan The evaporator fan starts a few minutes after the chiller is turned on and runs
continuously during normal operation defrost and CCP mode, and stops
when the front door is open or if the electronic controller displays ‘Err’
indicating a fault within the refrigeration system.
Condenser
Fan The condenser fan runs continuously when the chiller is on except if the
electronic controller displays ‘Err’ indicating a fault within the refrigeration
system.
Temperature
Probes Two temperature probes feed data to the electronic controller - the control
probe and the evaporator probe. The control probe 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.
Door Switch The chiller is fitted with a door switch below the front door (electronic
controller side). A small magnet in the door frame activates the switch. The
door switch tells the electronic controller to turn off the evaporator fan motor
(i.e. if door opened) during normal run operation, initiate Energy Saving
mode if the door is not opened for four hours and to reactivate Normal mode
if the door is opened for a period of time during night mode.
Defrost Cycle The first automatic defrost occurs 3 hours after the chiller is switched on. During
the defrost cycle the compressor stops and the evaporator fan runs
continuously. The defrost cycle will terminate (stop) when the evaporator
probe reaches 6
°C or after the defrost cycle has been running for 60 minutes.
Lighting The chiller is fitted with bottom sign lights and interior pillar lights. The lights
will come on when the chiller is initially plugged in. When in Normal mode
the sign and interior lights are on. When in Energy Saving mode the sign and
interior lights are off. Press the Light button on the electronic controller
faceplate to manually switch the sign and interior lights on and off (see
page 7).

Messages and Alarms
Controller
Display The following table explains messages that the electronic controller displays
and related alarms. Alarms signal unexpected operational changes in the
chiller and can be muted by pressing the alarm mute (up) button on the
electronic controller faceplate (see page 7).
Display Description
The chiller is in ‘Normal’ mode and the electronic
controller displays the chiller temperature.
The chiller is in ‘Energy Saving’ mode. When in Energy
Saving mode the temperature inside the chiller is
moderated and the cabinet lights turn off. The lights
can be switched on and off by pressing the light button
on the controller faceplate, and the chiller can be
switched into ‘normal’ mode by pressing the Energy
Saving button on the electronic controller faceplate.
The front door has remained open for over two
minutes. An alarm sounds, and the compressor and
evaporator fan turn off.
Regulation probe fault.
Evaporator probe fault.
There is a refrigeration system error and the controller
turns the chiller off to avoid damage. An alarm sounds,
and the compressor and evaporator fan turn off.

Programming the Electronic Controller
Parameters The 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 SC112N-A chiller uses program ‘102’).
The electronic controller parameters can be modified using the keypad.
Access to the parameters is protected by a password to prevent accidental
or unauthorised modifications. Only an authorised service agent should
modify the parameters.
To access the parameters
1. Press and hold the Set (mute) button for 5 seconds until the display shows
‘PS’ (password)
2. Press the Set (mute) button. The display shows ‘0’.
3. Use the ES (up) and Light (down) buttons to select password ‘22’ (default
password).
4. Press the Set (mute) button to confirm the password. The display shows
‘PS’.
5. Use the ES (up) and Light (down) buttons to scroll the parameter codes and
locate the required parameter.
Parameter categories can be identified by the initial symbol or letter of the
code, and the icon displayed on the electronic controller faceplate:
6. Press the Set (mute) button to display the value associated with the
parameter code.
7. Use the ES (up) and Light (down) buttons to increase or decrease the value
of the parameter.
8. Press the Set (mute) button to temporarily save the new value. The display
shows the parameter code.
Note: If no buttons are pressed for 60 seconds or the power is disconnected
before the temporarily saved values are permanently saved, the temporarily
saved values will be cancelled and the previous setting will be restored.
9. If necessary, repeat steps 5 - 9 to change other parameters as required.
10. Press and hold the Set (mute) button for 3 seconds to permanently save the
parameters and exit the parameter menu.
