4.7 Temperature monitoring
Temperature monitoring curve
If the temperature reaches the set limit ϑ1, the output relay K1 (change-over contact) will
change its switching state.
The output relays return immediately to their original state once the temperature reaches the
respective hysteresis value.
The limit ϑ1 is set for overshoot or undershoot to be monitored.
The cable length of the sensors can be compensated for with three-wire measurement up to a
maximum cable resistance of ... ohm.
