19.13 CLEAN MODE
The S3C Case Control supports a Clean Mode. Putting the
control in this state shuts off refrigeration and evaporator
fans, suspends defrost requests and disables all alarms. They
will remain off until the user terminates the Clean Mode.
This allows for either cleaning of the case or performing
service functions that require the case to be in an “OFF”
state. Clean Mode can be initiated or terminated using any
S3C Display Module (DM) in the case line-up.
Warning:
The Clean Mode feature is not to be used
for safety critical servicing. Use proper lockout tag out
producers, as defined by local requirements and codes, on
the case if electrical repair or other safety critical servicing
is required.
