5.8 PTC-thermistor
A motor thermistor or thermistor contact can be connected to analog input 2, terminal 10.
Set P1-13 to 5 or 10, make sure functionality for other inputs follows your specification. If not,
adjust functionality manually in parameter group 9. Contact Beijer Electronics for further
assistance.
Put P2-33=2, “ ".
Inverter will trip with open contact or a resistance above 2.5 kOhm. Input is not ATEX approved.
The cable for PTC-wires must be shielded and well separated from the motor cable. Otherwise an
external PTC-relay might be needed due to disturbances.
