Mains Voltage Failure; Behaviour When The Mains Voltage Is Restored - Busch-Jaeger Busch-Wachter DualLINE 6813/11 Series Operating Instructions Manual

12 Mains voltage failure

12.1 Behaviour when the mains voltage is restored

In the event of an interruption of mains power, the Presence Watchdog reacts as
follows:
a. Interruption ≤ 200 ms
– No change of the switching status
b. Interruption > 1 s (reset)
– The device performs a self-test for approx. 1 minute
After this, the Presence Watchdog switches as defined.
The Presence Watchdog is equipped with an EEPROM memory.
This ensures that all settings are preserved when the voltage is
restored.
IR remote control via the hand-held transmitter 6010 is not
possible until 1 minute after the voltage has been restored.
