Retriggering; Switch-Off Pre-Warning - ABB i-bus KNX Product Manual

11.6.6.4

Retriggering

Options:
Deactivated:
■
– The set switch-off delay always runs to its end, so that a telegram is always sent via
object "GFx: output" after the delay time has expired.
Activated:
■
– The switch-off delay is always restarted when a telegram is received via the "GFx: input"
object.
The parameter is used to specify whether the switch-off delay is restarted when a further
telegram is received via object "GFx: input". This behaviour is called retriggering.
For example, a retriggering makes sense for a switch-off delay for movement detectors. This
always resets the switch-off delay as long as movement is detected.
If telegrams with different values are received during the retriggering phase, only the last value
received is always sent via the "GFx: output" object after expiration of the delay time.
11.6.6.5

Switch-off pre-warning

Options:
Deactivated:
■
– The staircase lighting goes out without flickering at the end of the switch-off delay.
Activated:
■
– The staircase flickers before the expiry of the switch-off delay.
Before the staircase lighting switches itself off, the end of the illumination period is signalled by
means of brief flickering or dimming darker. The user can then keep the light on in time.
The parameter is used to specify whether an additional value is sent via the output object just
before the switch-off delay expires.
