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 parameter 1-90 Motor Thermal Protection to [2] Thermistor Trip.
• Set parameter 1-93 Thermistor Source to [6] Digital Input.
