4.3. Memory function
Use
The standard setting of the dimmer is without memory function. You can use the fourth DIP switch behind the
control button to activate or deactivate this function:
DIP switch position
DIP switch up
DIP switch down
The last dimming level set before switching off the dimmer is saved in the permanent memory of the dimmer if
the memory function is activated. In the event of a power failure, this value will not be lost.
If the memory function is activated, the dimmer switches on for the first time at the default dimming level chosen
by the manufacturer. Thereafter, the lighting will be dimmed at the last set value.
Dimming dimmable economy lamps with memory function
The dimming profile is set up so that the dimmer is first switched on to its maximum light intensity for a short
time and then returns to the dimming level saved in memory. All economy lamps can be switched on like this.
5. TROUBLESHOOTING
The operation of the dimmer can be disturbed by signals that are sent over the mains. This is not a defect.
Problem
Cause
The dimmer does not work.
The mains voltage is not
connected.
The load is not connected.
The allowable load is too high.
The lamp or the wire is defective. Replace the lamp or the wire.
The minimum dimming level has
been set too low.
The dimmer switches itself off.
The thermal overload
The red LED on the dimmer
(temperature too high) and the
flashes.
short-circuit protection have
been activated.

Action
Connect the device to the mains
voltage.
Connect the load correctly as
shown in the wiring diagram.
Provide for a lower load.
See section 3.2. to set the mini-
mum dimming level.
Check whether the load is too
high. When doing this, keep
in mind the reactive power of
ferromagnetic transformers.
Check the temperature in the
flush-mounting box (max. 35°C).
Check whether mixed loads are
being used.
Check the ambient temperature
and the positioning conditions. If
necessary, reduce the connected
capacity.
Check whether you have set the
DIP switches correctly for the
type of lamp used.
