Cause : Sensor type mismatch or Faulty wiring between an encoder interface module and the temperature sensor.

1. Check the settings of supervision source parameters 35.11 and 35.21 against 91.21 and 91.24.

2. Check the wiring of the sensor.

The auxiliary code (see the event log) identifies the interface module. (0 = Module 1, 1 = Module 2).

@click2electro Where is that sensor located, to determine if it is that or if it is the module or the electronic card?
