Faults and Alarms
The following table explains faults and alarms that the electronic controller may log and display.
If a fault occurs, the fault - alarm indicator is lit on the controller faceplate, but no message is
displayed. Faults do not affect product temperature, and require no action from the shop owner.
Alarms are logged and the alarm message is displayed on the controller faceplate. Alarms may
result in abnormal product temperature.
Some faults and alarms can be cleared by the shop owner, and others can only be cleared by a
service technician.
If the cabinet is connected to the power supply and has warm product, check the SCS Connect
Field App for active fault or alarm, and investigate. If the cabinet does not have an active fault or
alarm, check the app statistics to determine if and when the controller signalled a fault or alarm.
Refer to the tables below for faults and alarm descriptions and possible causes and actions. The
service tech type column refers to the service tech skill level required to complete a task. Refer to
the SKOPE HC Service Policy (available from SKOPE) for service tech type details.
