Electronic Controller Operations
Overview The SC112N-AC fridge is fitted with a CAREL ECOBOX 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 fridge temperature and
signals temperature alarms. It uses two temperature probes within the
refrigeration system to collect data and runs the fridge accordingly.
The electronic controller is pre-programmed; SKOPE does not recommend
changing the settings unless it is absolutely necessary. To ensure efficient
operation, the electronic controller automatically forces a defrost cycle when
required.
IMPORTANT
The electronic controller must only be adjusted by an authorised
service agent.

Service Manual
Running the Fridge
Operating
Modes
The electronic controller will automatically switch the fridge between Day
and Night modes depending on use, and into Cold Climate Protection (CCP)
mode if necessary (see “Cold Climate Protection (CCP)” on page 10).
If the front door (on the electronic controller side) is not opened for
four hours, the fridge will automatically enter Night mode and the sign and
interior lights will switch off. To manually switch the fridge between Day and
Night modes, press and hold the Day - Night button on the electronic
controller faceplate. The fridge can also be bought into Day mode by
opening the front door (on the electronic controller side).
Compressor The compressor cycles on and off during Day and Night modes. It does not
run when the fridge is in defrost mode or when the fridge is in CCP 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 fridge 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 fridge 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 fridge
temperature, provides the fridge temperature for the electronic controller to
display, and notifies the electronic controller of any erratic or abnormal
temperatures that could identify a problem within the refrigeration system.
The evaporator probe controls the refrigeration system defrost initiation and
termination.
Door Switch The fridge is fitted with a door switch below the front door (on the 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 the door is opened) during normal run operation, to initiate Night mode
if the door is not opened for four hours, and to reactivate Day mode if the
door is opened during night mode.
Defrost Cycle The defrost cycle will begin after three hours of cumulative compressor run
time or during No-Downward Tendency Protection (see “No-downward
Tendency Protection (NDTP)” on page 10). During the defrost cycle the
compressor stops and the evaporator fan runs continuously. The defrost
cycle will stop when the evaporator probe reaches 6°C or after the defrost
cycle has been running for 60 minutes.
Lighting The fridge is fitted with top and bottom sign lights, and interior pillar lights.
The lights will come on when the fridge is first plugged in. When in Day mode
the sign and interior lights are on. When in Night mode the sign and interior
lights are off. Press the Light button on the electronic controller faceplate to
switch the sign and interior lights on and off manually. The lights will remain
on and cannot be switched off when the fridge is in CCP mode.

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 fridge and can be muted by pressing the Alarm Mute (up)
button on the electronic controller faceplate (see page 8).
Cold Climate
Protection
(CCP)
The fridge will enter CCP mode if the ambient temperature becomes too
cold. This is detected by the control probe (at the evaporator air out)
measuring a temperature of ≤0°C continuously for 30 minutes. The lights will
stay on and cannot be switched off while the fridge is in CCP mode. The
fridge will return to its previous mode (Day or Night) once the control probe
measures ≥2°C at the evaporator air out.
No-downward
Tendency
Protection
(NDTP)
The electronic controller starts NDTP when the compressor has been
running for ≥30 minutes and the control probe temperature does not
decrease. This will force a standard defrost cycle (see “Defrost Cycle” on
page 9). If the electronic controller is required to force consecutive defrost
cycles due to NDTP, the refrigeration system error alarm will start (Err) and
the fridge will shut down indicating a fault within the refrigeration system.
Table 3: Controller display
Display Description
The fridge is in Day mode and the electronic controller displays
the fridge temperature.
The fridge is in economical Night mode. When in Night mode the
temperature inside the fridge 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 fridge can be
switched into Day mode by pressing the Day - Night button on the
electronic controller faceplate.
The fridge is in Cold Climate Protection (CCP) mode. The fridge
enters CCP mode if the ambient temperature gets too cold. The
lights remain on and cannot be switched off.
The front door has remained open for over two minutes. An alarm
sounds, and the compressor and evaporator fan turn off.
There is a refrigeration system error and the controller turns the
fridge off to avoid damage.
Control probe failure. The control temperature probe has failed
and an alarm sounds.
Evaporator probe failure. The evaporator temperature probe has
failed and an alarm sounds.

Before
Servicing
Overview
Ensure you have read and understood this manual before starting any
servicing.
Important
• SKOPE hydrocarbon refrigeration systems must only be serviced by
appropriately skilled and qualified refrigeration mechanics.
• Servicing a sealed refrigeration system must occur at a hydrocarbon
workshop or service area with dedicated hydrocarbon equipment and
personal protective equipment (PPE).
• All local hydrocarbon storage and handling regulations and procedures
must be followed at all times.
Ensure all electronic controller alarms diagnostics and refrigeration system
diagnostics are performed to confirm a refrigeration system fault is present.
Check all components including the electronic controller and electrical
systems.
Ensure your work area is well ventilated.
Safety hazards
The main hydrocarbon safety hazards are:
• Flammability
• Venting of hydrocarbon and compressor oil
• Asphyxiation
Refrigerant identification
Correctly identifying the refrigerant is critical to maintain safety and the
correct functioning of the cabinet.
• The cabinet rating label (located in the upper inside of the cabinet) states
the refrigerant type.
• Warning labels are fitted to hydrocarbon refrigeration cabinets to
indicate the use of hydrocarbon refrigerant.
Personal protective equipment (PPE)
Correctly wear or use all PPE required by local regulations and procedures
during servicing.
Service equipment
Only use dedicated hydrocarbon service equipment which is hydrocarbon-
compliant. Electrical equipment that could be exposed to the refrigerant
must be intrinsically safe.
In addition to standard tools for accessing and removing parts, specialist
tools are required for completing the refrigeration system service tasks in
this manual:
• Intrinsically safe refrigeration vacuum pump, rated by the manufacturer
as suitable for use with hydrocarbon refrigerant
IMPORTANT
Use only dedicated hydrocarbon SKOPE OEM spare parts.
DO NOT use alternative parts.
For safety compliance, use only SKOPE-supplied components
specified for the appliance.
