Temperature monitoring
•
The temperature monitoring by the PTC thermistor or temperature sensor (PT100) must be
evaluated.
•
Only connect to the inputs suitable for the relevant monitoring type.
•
Maximum permissible test voltage for PTC thermistors: 2.5 VDC.
•
When monitoring with a temperature sensor (PT100), the monitoring unit must be set to the limit
value (
