4.2.10.4 Klixon
The Klixon type thermal circuit breaker uses a KLIXON® metal dish. At a predetermined overload, the heat caused by the current
through the disc causes a trip.
Using a digital input and 24 V as supply:
Example: The drive trips when the motor temperature is too high.
Parameter setup:
Set
