Motor-protective system ZEV

11/01 AWB2300-1433GB

Short-circuit monitoring of the thermistor circuit

A current monitor can be installed in the thermistor circuit, 
in order to monitor the current high limit and short-circuit as 
shown in the following circuit diagram.

Hazard due to sensor failure is also excluded when the 
temperature is being monitored by means of thermistors, 
since this circuit switches off the unit instantaneously.

Warning!

Response of the thermistor monitoring unit must also 
directly shut down a motor that is controlled by means of 
an inverter. Appropriate provisions must be made in the 
circuit.
