maximum permissible coolant and the updated measurement of the object
temperature.
3.24.4 Coolant Temperature Acquisition
To permit acquisition of the coolant temperature, an analogue I/O module Y must
be fitted to the P631. 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.
