When Forced operation ends, the brightness value updated in the background is set. The ballast or
group returns to the state it was in before forced operation. If an additional function was active, e.g.
Staircase lighting or Slave, it will also be active after Forced operation. If the Staircase lighting
function was activated before Forced operation, it goes into standby when Forced operation/Block
is removed. If the Slave function was activated before Forced operation, it continues once forced
operation is removed and responds to the master again.
State of forced operation
on bus voltage recovery
Options: Inactive
Switch on by force
State before KNX voltage failure
This parameter defines the state of a forced operation after bus voltage recovery.
•
Inactive: The ballast/group is enabled after bus voltage recovery and is no longer subject to
Forced operation. Any parametrized Staircase lighting functions will be active in standby if they
were activated before Forced operation. A slave will start responding to the master again if it
was activated before Forced operation.
•
Switch on by force: The ballast/group is forcibly operated and switched on at the brightness
parametrized in Brightness value when switched on by force.
•
State before KNX voltage failure: The ballast/group is restored to the state it was in before the
voltage failure.
