To permit acquisition of the coolant temperature, an analogue I/O module Y must be fitted to the P632. If this module is not present then the setting at THRM1: Default CTA PSx is used in the calculation of the tripping time.

pThe setting at THRM1: Bl. f. CTA fault PSx defines whether the thermal overload protection function will be blocked in the event of a fault in the coolant temperature acquisition.
