9.2 Testing the temperature sensors

9.2.1 Safety

Only professional personnel may test the temperature

sensors.

9.2.2 Testing the resistance values

DANGER

Risk of death by electrocution!

Remove the controller from the power supply before

opening the casing.

The temperature is recorded by resistance sensors.

These are PT1000 temperature sensors. Depending on

the temperature, the resistance value also changes. A

potentially defective sensor can be checked using an

ohmmeter.

Measuring resistance values

Disconnect the relevant temperature sensor from

the controller.
Measure the resistance value. The typical resistance

values, depending on the temperature, are listed in

the following table. Please note that small devia-

tions are permissible.
