3.7 Special feature CV programming for control panels that
Switch off the programming track
Some control panels (Uhlenbrock® Basis®, Daisy 2® Startset, Piko® SmartControl® light, etc.) only switch on the supply voltage to the programming track during
programming. The
green
LED next to the power connector of the DR4024 indicates whether the programming track always outputs voltage. If this does not
light up con nuously, the programming track is switched off. This leads to the DR4024 requiring a different programming or reseDng procedure than usual.
This procedure is described in this sec on.
1.
Now that you have determined that the
green LED
next to the power connector is not permanently lit, disconnect the
POWER
and
SIGNAL
connectors from
the
programming track.
2.
Connect the
POWER
and
SIGNAL
connectors to
the main track
of your control panel.
Now the
green LED
next to the POWER connector should light up permanently.
3.
Now press the programming bu2on on the DR4024.
The
red LED
will light to indicate that the DR4024 is in programming mode
4.
Now disconnect the POWER
and
SIGNAL connectors from the
main track
(Track Out).
5.
Now reconnect the POWER
and
SIGNAL connec1ons to the
programming track
of your control panel.
The
green
and
red
LEDs now go out because the
programming track
is not constantly supplied with power.
The programming mode of the DR4024 remains unchanged.
6.
Select the CV programming func1on via the
programming track
in your central, app or handset controller and program the desired CVs one aJer the other.
(Further informa on on CV byte or CV bit programming can be found in the opera ng manual of your control panel)
AJer you have successfully changed all desired CV's, you must exit the programming mode of the central unit before proceeding with the next step.
7.
Disconnect the POWER
and
SIGNAL connec1ons from the
programming track
.
8.
Connect the POWER
and
SIGNAL connectors to the main track of your control panel.
Now the
green LED
next to the POWER connector and the
red LED
both light up again.
The
red LED
indicates that the DR4024 is s1ll in programming mode.
9.
Now press the programming bu2ons on the DR4024. The
red LED
goes out and the programming mode is terminated.
