If 1-byte telegrams with different values are receive during the retriggering phase, the
values are immediately transfer to the output and the light-on time is restart. With the
"no" setting, the set light-on time always proceeds to the end so that a telegram is always
sent out on the "Output" object after the light-on time.

Extended parameter – Switch-off prewarning
Options
Deactivate
Activate
Via the "Switch-off prewarning" parameter, you can activate whether an additional value
is sent out on the output object shortly before expiration of the light-on time. This signals
to the user that the staircase lighting time has almost expired and that the light will be
switching off shortly.
12.28.5
Extended parameter – Overwrite light on and switch off prewarning time for
download
Options
Deactivate
Activate
Telegrams with new times can be receive via the 2-byte communication objects "Light-on
time" and "Switch-off prewarning time". The received 2-byte values are written to the
memory of the control element and are retained even after a bus power failure and
subsequent return of voltage.
The "Overwrite light-on and switch-off prewarning time for download" parameter specifies
whether the received storage values are to be retained for a reprogramming of the control
element or whether the storage values are to be replaced by the values specified in the
parameterizing software.
