Function
The signal OH is derived from a comparator with hysteresis. The switch-off threshold is 85°Candis
fixed. The hysteresis is also fixed and amounts to 5K, i.e. the reclosing point is 80°C.
Features:
•
LECOM no.: 50
•
Reaction: TRIP (cannot be modified)
Tripping can have the following causes:
•
The ambient temperature is too high.
Remedy:
– Install a fan into the switch cabinet.
•
The controller is overloaded in its arithmetic mean, i.e. overload and recovery phase exceed
100 %.
Remedy:
– Reduce overload phase
– Use more powerful controller
