Overtemperature protection
The overtemperature protection monitors the internal temperature.
It has two threshold values (see Technical data):
- Twarn: If the internal temperature exceeds Twarn, the bit "Warning Temperature" in the process data object "DPO Inputs Device" is set.
- Terr: If the internal temperature exceeds Terr, all output voltages are switched off and the bit "Error Temperature" in the process data object "DPO Inputs Device" is set.
Resetting an error state
- 1. Allow the box to cool down until the internal temperature has fallen below Twarn.
- 2. Apply a positive edge on the output variable
“DPO Outputs Device” > “Global Reset”.
- The error message is reset.
- All output voltages are switched on again, provided no other protective function prevents this.
