In Service; Behaviour On The Failure And Reinstatement Of The Bus Power Supply - Gewiss GW 90 852 Handbuch

The 2 local command buttons for each channel (figure A) are used to command the
shutters or blinds as follows:
• Pressing and long holding (> 0.5 s) the button, it moves the shutter or blind UP or
DOWN for the preset Movement Time.
• If the shutter or blind is moving, press and instantly release (≤ 0.5 s) either button to
stop it.
• In blind mode, when the blind is at a standstill, each time the button is pressed and
instantly released (≤ 0.5 s) will alter the inclination of the laths.
The loads can be commanded via the local manual command, even without a BUS
voltage: in this case it is necessary to use the auxiliary 230V AC power supply input.
Transitional positions of the shutter or blind
When executing a scene, the shutter or blind will move to the previously memorised
transitional position.
When an alarm or override status is cancelled (receipt of an alarm or override end
command) the actuator will execute the last memorised command and, if there are none,
it will move to the position before the alarm or override status occurred.
Behaviour on the failure and reinstatement
If the power to the bus decreases below 18 V dc for over 1.5 ms the movement of the
shutter or blind is interrupted
When the power is reinstated on the bus, the shutter or blind does not move until it
receives a new movement command. If an alarm or a forcing is active, the outputs return
to the status they occupied prior to the BUS failure.
This device requires no maintenance. Use a dry cloth for possible cleaning.
