READ THE COMPLETE MANUAL BEFORE ATTEMPTING INSTALLATION AND ACTIVATING THE SYSTEM.
1. DESCRIPTION
This 350W universal, modular dimmer is intended for DIN-rail mounting and is 1U wide. The device is suitable
for dimming resistive, inductive and capacitive loads, dimmable LEDs and economy lamps (CFLi). The dimmer
functions both as a phase control dimmer and as a reverse phase control dimmer. The choice of lamp type can
be set using the first 3 DIP switches under the hinged cover. The dimmer can be used with or without memory
and is equipped with an automatic detection and indication of faulty conditions (overload, short circuit, ...).
2. INSTALLATION AND CONNECTIONS
To connect the load and the necessary power supply voltage, see step ➥➊.
To select the correct load, see step ➥➋. To regulate the minimum level in case of incorrect light output, see
step ➥➌. In this way the maximum dimming range of each lamp can be achieved. If everything is correctly
connected and the power supply and the lamp are switched on, then the indication LED on the dimmer will
be on; if an error has occurred, then the LED will flash. Make sure that no mixed loads are used on 1 dimmer.
Installation recommendations
- Preferably place the dimmers at the bottom of the distribution board.
- Check the temperature. If the temperature in the distribution board rises too high (max. 35°C), provide additional
ventilation. Provide sufficient space at the top of the board. Place a ventilator if necessary.
3. OPERATION AND USE
3.1. Normal operation
The control occurs via N.O. push buttons (non-illuminated) or potential-free push buttons (8-24V). Press briefly to
switch on and off. Hold down to dim up and down. When holding down, the dimming direction is switched after
each interruption (dimming up -> stop -> dimming down-> stop -> dimming up -> etc.). Once the maximum
intensity has been reached, the dimming level remains unchanged. The last dimming level reached before the
dimmer is switched off is saved in a memory (3.3). Up to 30 N.O. contacts (170-0000X) can be connected in
parallel at any one time (max. distance 100m). The push buttons are not galvanically isolated.
3.2 Two extra control modes
The following 2 additional operating modes are possible: These can be selected with DIP switch 4 under the
hinged cover of the dimmer. (see step ➥➊).
Mode 1: One-button control
Bij By selecting this mode, the dimmer works with push-button control (N.O. or potential-free). Press briefly to
switch on and off. Hold down to dim up and down. When holding down, the dimming direction is switched after
each interruption (dimming up -> stop -> dimming down-> stop -> dimming up -> etc.). The last dimming
level reached before the dimmer is switched off is saved in memory (see 3.3). This mode is selected by turning
DIP switch 4 off (downward) (see step ➥➋ settings). For the wiring diagram, see step ➥➊ one-button control.
Mode 2: Staircase function
By selecting this mode, the lighting switches off automatically after 3'. This mode is selected by turning DIP switch
4 on (upward) (see step ➥➋ settings). For the wiring diagram, see step ➥➊ normal operation.
3.3 Memory function
The dimmer can be used with or without memory. The standard setting of the dimmer is without memory function.
You use the control button to change this function. Dim up to the maximum lighting intensity and then continue
to press the control button for 10s. After 10 sec. the light dims from 100% to a lower light level to indicate that
this function has been switched on. After this change in light intensity, immediately release the push button.
Repeat the procedure to deactivate the memory function. This function, and the last set light level, is stored in
a non-volatile memory; i.e. they will not be lost in the event of a power failure. With the memory function, the
dimmer switches on the first time at a light level chosen by the manufacturer. Thereafter, the dimmer switches
on at the last set value.
When dimming dimmable economy lamps with the memory function activated, the dim profile is set up so that
the dimmer is first switched on to its maximum capacity for one second and then returns to the dimming level
saved in memory. This ensures that each economy lamp, even those with memory function, can be switched on.
With memory
- Press briefly = on at previous level / off
- Hold down when off = the dimmer dims up from the minimum light level
- When dimming up, the dimmer stops at the maximum.
- When dimming down: the dimmer stops for 2s. at the min. and then dims up
- A renewed (long) press reverses the dimming direction.
Without memory
- Press briefly = on at maximum / off. The rest of the operation is the same as the operation with memory.
- Push-button control:
press briefly < 400ms. hold down > 400ms.
= on / off = dimming up / dimming down-
3.4 All-off function
If another control point is connected to the all-off input, then this control can switch off all lighting that is con-
nected to this dimmer. For the wiring diagram, see step 1: all-off function.
3.5 Lamps
All dimmable lamps. See table below.
Setting the correct load occurs using the DIP switches.

3.6. Meaning of the red indication LED
The LED turns on:
- the dimmer is connected correctly (when installing)
- and the load is switched on.
The LED is flashing: - error condition; the dimmer is not connected correctly or there is an overload, short-circuit
or an incorrect setting.

4. TROUBLESHOOTING
Possible causes of dimmer malfunction:
- the mains voltage is not connected
- the load is not connected or the connected power consumption is too high
- the lamp or the cable used is defective
- the thermal protection has been activated
- the minimum dimming level is set too low (for operation with memory)
- a combination of the above causes
The dimmer is equipped with a thermal protection. If the temperature increases excessively due to overload,
switch the dimmer off. If this happens
- check whether the load is too high. When doing this, keep in mind the reactive power of ferromagnetic transformers.
- check the temperature in the distribution board (max. 35°C).
- check whether mixed loads are being used
- check the ambient temperature and positioning conditions. Depending on these factors, the maximum connection
output must be reduced.
- check whether the correct lamp type has been selected
- 10% per 5°C over the ambient temperature 35°C
The dimmer can be switched back on (after cooling) by switching on the control again.
- The indication LED keeps flashing. This indicates:
5. USAGE WARNINGS
- Control signals that are sent via the mains can interfere with the operation of the dimmer. (This is not a defect.)
- The dimmer is never electrically separated from the mains due to the operation of the control. Therefore, all parts
remain "live" even if the load (e.g., the light) is "off".
- This appliance is not suitable for controlling motors
