ATTENTION!
Light dimming:
– At the dimmable outputs of light, only 230V consumer which are suita-
ble for
phase cut off
, will be permitted.
Fan control:
– At the dimmable outputs of fan, only 230V consumer which are suita-

phase cut on
, will be permitted.
ATTENTION
DANGER!
Danger to life due to electric potential!
Before starting any maintenance jobs, the control unit must be sepa-
rated from the mains at all poles!
ATTENTION!
Note ESD protection!
Do not touch on electrical parts because of ESD protection.
Take appropriate protections. Touch a grounded piece of metal as a
minimum protection.
You can deactivate the light and fan control using jumpers:
NoLu: Fan control (Terminal 1) activated.
NoLu: Fan control deactivated, only On/Off.
NoLi: Dimming of light (Terminal 3) activated.
NoLi: Dimming of light deactivated, only On/Off.
The jumpers are located only on one side of the pins (as in the picture above) or they
are in the by-pack kit of the control unit.
Deactivate user menus for dimming with dip switches:
DIP 4=ON, Menu for Fan control deactivated.
DIP 5=ON, Menu for Light dimming deactivated.
If the light dimming no longer works due to a defect in the lamp, the FET T1, T2 and
possibly the fuse Si2 have been destroyed. When replacing the FET, place the new
component back on the base in the correct position (note the metal flag). Make sure that
all connections are correctly inserted into the base and press in carefully.
If the fan control has been destroyed due to a defect, the same applies to triac “Tri1”.
