8.45 Alarm# 48 Over Temperature Switch Tripped
Condition
An overheating of the drying heaters, recirculation heaters or reservoir heaters has been detected.
Alarm is triggered by...
• One of the over temperature switches (OTS) tripped.
– drying heaters OTS

IMPORTANT: Each heater circuit breaker (CB5, CB6, CB7, CB8) is mechanically connected to a shunt trip. Whenever a heater
over temperature is detected, (IO4/2 input off), control activates output IO10/7 to energize all shunt trips which trip all heater
circuit breakers. CB5, CB6, CB7 and CB8 have to be reset manually.
IMPORTANT: When washer is repaired, ensure OTS is reset and manually put circuit breakers CB5, CB6, CB7, and CB8 in ON
position (red) before powering up washer/disinfector.
