| Info: | Temperature limit |
| Data type: | REAL |
Description:
Runtime error if the calculated temperature of the pre-charging resistance exceeds the limit (see INFO).
Reaction:
The main relay is opened and the RDY-LED and ERR-LED flashes synchonous in 3 seconds cycle.
The error state can only be exited by rebooting the module (e.g.: Switching off the power supply and the external 24V supply or reboot by command).
Cause/Remedy:
The module is operated outside the specifications:
- The switch-on interval is too short
- The DC bus capacitance is too large
- The Ambient temperature is too high.
Short-circuit in the DC bus
External pre-charging circuit has failed
Paralleled power supply module has failed
Paralleled power supply module has a power on delay
