The 24-volt feed power supply is monitored. As soon as the power supply drops (e.g. main switch off) the PC will be shut down under control. The power supply of PC, drives and CAN bus is assured via the UPS. Thus all machine data can be securely saved.
Remedy
PC switches off immediately when the main switch is off:
- Check buffer batteries.
The PC is shut down automatically by the GCC:
- Check the 24 volt DC IN input in the industrial computer.
