Safety instructions
Electrical equipment must only be installed and assembled by a qualified electrician in accordance with the relevant installation standards, guidelines, regulations, directives, safety and accident prevention regulations of the country.
Failure to comply with these instructions may result in damage to the device, fire or other hazards.
Hazard due to electric shock. The device is not suitable for safe disconnection of the mains supply. Even when the device is switched off, the load is not isolated from the mains supply.
Do not connect non-dimmable lamps, their transformers or operating devices. Observe manufacturer’s data.
These instructions are an integral component of the product and must be retained by the end user

Control
Fig. 3: Push-button dimmer operation
| Load status | Action | Result |
|---|---|---|
| OFF | Short press of push-button | Switch ON with saved switch-on brightness |
level.
0%| Short press of push-button| Switch OFF and save brightness as switch-on brightness level.

Table 1: Push-button dimmer and slave unit operation
Adjusting the minimum brightness
The minimum brightness level can be adjusted with the push-button dimmer to
prevent poor switchon behaviour or flickering of the load in the lower dimming
range.
-
Switch off load.
-
Press and hold button for approx 10 seconds.
The lamp and the status LED will flash once after 3 seconds and then both flash a second time after 10 seconds. -
Release push-button.
The device is now in minimum brightness setting mode. The status LED is flashing fast and the load is switched on at minimum brightness.
Depending on the lamp, the minimum brightness level of the lights installed may be too low and the lights may appear off, gradually increase the brightness level by repeatedly pressing the button.
If no actions are performed within 10 seconds, the dimmer exits programing operation. -
Briefly press the button repeatedly.
The brightness increases gradually. -
Once desired min lighting level is reached, wait 10 seconds for device to store the setting.
The load will be switched off, the dimmer returns to normal operation.
If your minimum setting is set too high, wait for the device to exit programming mode and repeat the above programming procedure.
Configurable additional functions
The additional functions can be configured by pressing the push-button dimmer for the required number of times.
Kick-start
A short voltage burst when lamp is initially turned on to support lamp start-
up.
Reduced maximum brightness
A non-adjustble voltage reduction for suppressing flickering at maximum brightness.
Status LED
In factory state the status LED lights up only, if the lamp is switched on. As described thereunder it may be set to be permanently on.
Recovering the previous load state when power is restored after a power cut
The status of the load prior to power loss will be restored at power-on.
Configuring additional function
-
From the off position, press & hold the button for approx 10 seconds or more.
The status LED and the lamp will flash once after 3 seconds and then both flash a second time after 10 seconds. -
Release push-button.
The device is now in minimum brightness setting mode. The status LED is flashing fast and the load is switched on at minimum brightness. -
Press and hold the button for 3 seconds until the lamp flashes once again and the status LED gets off.
-
Release push-button.
The status LED starts blinking fast again. -
Select the additional program function required by pressing the button slowly, waiting for the load to flash after each press (selected from Table 2) before pressing again.
After approx. 10 s without operation, the change of additional function is stored and the device switches to standard operation.
| Configurable additional functions | Factory settings | Number of button pushes |
|---|---|---|
| Kick-start | OFF | 1 x |
| Reduced maximum brightness | OFF | 2 x |
| Status LED lights up only when ON | ON | 3 x |
| Recovery of the load state when the power is restored | OFF | 4 x |
Table 2: Confi gurable additional functions
Reset to factory setting
-
Press the button for approx. 10 sec. or more.
The lamp and the status LED will fl ash once after 3 seconds and then both fl ash a second time after 10 seconds. -
Release push-button.
The device is in fi ne adjustment mode for the minimum brightness level and the status LED starts fl ashing fast and the load is set to the minimum brightness level. -
Press button again for approx. 10 s or more
The lamp and the status LED will fl ash once after 3 seconds and then both fl ash a second time after 10 seconds. -
Release push-button
The status LED goes out and the reset has been completed, the dimmer is in standard operation with the factory settings being eff ective.
Information for electricians
Installation and electrical connection
DANGER!
Electrical shock when live parts are touched.
An electric shock can lead to death.
Isolate all power before working on the device and cover any live parts in the
area!

Table 4: Dimmer combination load reduction
Carry out loading of conventional, electronic transformers according to
manufacturer’s instructions.
Do not use non-dimmable 230 V LED lamps.
If 230 V LED lamps are used, the power supply to the dimmer can cause the lamp
to glow slightly even when it is switched off .
Troubleshooting
Dimmer switches off of its own accord.
The electronic overload protection has tripped.
Check the load connected (excessive load).
Reduce the number of lamps or use lamps with a lower power rating.
The electronic short-circuit protection has tripped. Check electrical
installation.
The load cannot be dimmed down sufficiently.
The dimming angle is set too high.
Decrease the value in fine-setting of the minimum brightness.
The load switches off while being dimmed down.
The dimming angle is set too low.
Increase the value in fine-setting of the minimum brightness.
The load does not switch on.
The dimming angle and brightness value are set too low.
Increase the value in fine-setting of the minimum brightness.
Load flickers while switched off .
LED load too low.
Increase LED load at output.
The LED load fl ickers due to the dimmer status LED power
Switch off dimmer status LED
The connected load cannot be dimmed or load fl ickers while switched ON.
Lamps are not suitable for dimming.
Be sure always to use dimmable loads.
Undefi ned fault during operation.
Slave unit cable length is too long or no separate slave unit cable has been
used.
Keep to slave unit cable length or, if necessary, use separate slave unit
cable.
Note:
LED loads should be tested with this dimmer prior to installation. Some LED
loads may not be compatible due to the type of LED driver within the LED
light.
