ABB i-bus® KNX FUNCTION
The following diagram shows the reaction on extension to quintuple the staircase lighting time:

4.1.13.1.2 Disable staircase lighting
The function Staircase lighting can be disabled via the group object Disable staircase lighting . If the
function Staircase lighting is disabled, the switch-on command is forwarded without time function in
the function chain (→ Function diagram of Switch Actuator, Page 77) and the output reacts according to
its parameterization.
4.1.13.1.3 Permanent ON
When the function Staircase lighting is active, the lighting can be permanently switched on via the group
object Staircase lighting permanent ON . The output remains on as long as Permanent ON operation is
active. Other functions continue to run in the background, but they do not trigger any switching opera-
tion. If Permanent ON operation is deactivated, the output will react to group object Switch .
The parameter Restart staircase lighting after end of permanent ON can be used to define how the light-
ing reacts after the end of Permanent ON operation.
The state of Permanent ON mode prior to download or bus voltage failure is restored after download or
bus voltage recovery.
4.1.13.2 Function Delay for switching ON and OFF
The function Delay for switching ON and OFF can be used to switch the output on and off with a delay.
If the Delay for switching ON is used, the delay time T
Switch-on takes place when the value 1 is received:
• on the group object Switch
• on the central group object Switch
• on the group object Scene 1...64
• on the central group object Scene 1 ... 64
• as the result of the → Function Logic, Page 84
• as the result of the → Function Threshold, Page 85
If the Delay for switching OFF is used, the delay time T
begins after switch-on.
D1
begins after switch-off.
