Reaction on bus voltage failure

The reaction on bus voltage failure can be parameterized in the parameter window A: General via the
parameter Reaction on bus voltage failure for each individual output. This parameterization has a direct
impact on the output contacts and has the highest priority.
Should a bus voltage failure occur during a movement, then the blind/shutter can still move in the opposite
direction.
After the contact positions on bus voltage failure have been set, the JRA/S cannot function until bus
voltage recovery.

Reaction on bus voltage recovery, download and ETS reset

The reaction on bus voltage recovery can be parameterized for each output. The device is ready for
operation after an initialization time of a few seconds after applying the bus voltage. Depending on the time
set in the General parameter window for Time-delayed switching of drives and the Sending and switching
delay time on bus voltage recovery in s [2...255], the individual outputs assume the parameterized position
after the initialization time.
After programming or an ETS reset, all the communication objects assume the value 0 (exception: End
positions = 1).
After programming, all the positions are invalid or deleted. After bus voltage recovery, programming or an
ETS reset, the blind/shutter is moved to the parameterized position and/or automatic sun protection
activated. If the option Position X or Individual position is set as the position after programming, then the
blind/shutter is moved along the shortest route to the target position via an end position to determine the
current position. After the movement has been completed, the status communication objects are updated
and send their value.
What is an ETS reset?
Generally an ETS reset is defined as a reset of the device via the ETS. The ETS Reset is triggered in the
ETS under the menu item Commissioning with the function Reset device. This stops and restarts the
application.
