Operating In Case Of Blackout; Preset Parameters - Gewiss SYSTEM Serie Handbuch

USER INSTRUCTIONS
The device is fitted with a backup battery that guarantees updating of the time and day of
the week in case of blackout.
When power is supplied by the battery alone there is an autonomy of 24 hours in the fol-
lowing conditions:
- time display active
- backlighting inactive
- output status display inactive
- relay switching not enabled (the relay contact retains the status prior to the blackout)
- front keys inactive (except when all 4 keys are pressed simultaneously)
In the absence of power, simultaneously pressing all four front keys causes disconnection
of the backup battery inside the device.
This function is used to preserve the efficiency of the battery when the device is not used
for a long period.
The battery is connected again automatically once the device has been connected to the
power mains.
The set programs are not lost either in the case of a blackout or in that of battery discon-
nection.
