Power-on behavior

After the operating voltage is switched on, the system is set to the operating state which it was in before the supply voltage was switched off.

For this purpose, all necessary operating parameters are stored in a permanent memory. If the system was disconnected from the supply in the armed state, this is entered as a fault in the status memory. The same applies if the system is disconnected from the supply voltage during an alarm output. The alarm output is continued as soon as the necessary supply voltage is available.
