DESCRIPTION

This universal, modular dimmer is intended for DIN-rail mounting and is 1 TE wide (17.5 mm). The dimmer is connected with three wires and is suitable for dimming dimmable LED lamps, dimmable economy lamps (CFLi), halogen lamps and incandescent lamps. The dimmer functions according to both the phase control and reverse phase control principle and is controlled via a NO push-button (170-0000x). The choice of lamp type can be set using the first three DIP switches under the hinged lid (see fig. 2). The dimmer can be used with or without memory and is equipped with an automatic detection and indication of malfunctions (overload, short circuit, etc.).

MOUNTING AND CONNECTION

To connect the load and the necessary input voltage, see fig.1. 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 a malfunction has occurred, then the LED will flash. Make sure that no mixed loads are used on 1 dimmer.

Installation recommendations

• The dimmers should ideally be fitted at the bottom of the electrical cabinet.
• If modular dimmers are fitted near to one another in the electrical cabinet, you can only connect 80% of the maximum permissible power. A minimal distance of 20 mm is required in order to utilise the full, maximum power.
• Check the temperature. If the temperature in the electrical cabinet rises too high (max. 35°C), provide additional ventilation. Ensure that any air is adequately vented at the top of the electrical cabinet. Install a ventilator if necessary.

OPERATION AND USE

General operation
The dimmer is controlled via an NO push button (230V AC or 8-24V AC/V DC). 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 set before switching off the dimmer is saved in the permanent memory of the dimmer if the memory function is activated. (see § 3.3.). Up to 30 NO contacts 170-0000x can be connected in parallel (max. distance 100 m).

Two extra control modes
The following two additional control modes are possible. These can be selected with DIP switch 4 under the hinged lid of the dimmer (see fig. 2).

Mode 1: One-button control
By selecting this mode, the dimmer works with an NO push-button control (230V AC or 8-24V AC/V DC). 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 set before switching off the dimmer is saved in the permanent memory of the dimmer if the memory function is activated. (see § 3.3.). This mode is selected by turning DIP switch 4 off (downward) (see § 3.7). For the connection diagram, see figure 1a (one-button control).

Mode 2: Staircase function
When this mode is selected, the light intensity of the light circuit will decrease to 30% after 3 minutes and the dimmer will switch off completely 1 minute later. The light intensity and the visible switch-off delay is lamp- specific. It is possible that these differ. This mode is selected by setting DIP switch 4 on (up) (see § 3.7). For the wiring diagram, see figure 1b (staircase function).

Memory function
The dimmer can be used with or without memory. The standard setting of the dimmer is without memory function. You use the NO push-button control to change this function. Dim up to the maximum light level and then continue to press the control button for 10 seconds. After 10 seconds, 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 selected by Niko. After that, the dimmer switches on at the last set value. For dimming dimmable economy lamps and LED lamps with the activated memory function, the dimming profile is set up in such a way that the dimmer is first switched on to its maximum capacity (boost function) for less than one second and then returns to the dimming level saved in memory. This ensures that each 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 2 sec. at the minimum and then dims back 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

All-off function
If another NO push-button control (170-0000x) is connected to the all-off input , then this control can switch off all lighting that is connected to this dimmer. For the connection diagram, see fig. 1 c (all-off function).

PLC interference suppression
This dimmer is equipped with interference suppression of PLC signals. This integrated interference suppression attempts to remove as many interfering signals as possible from the mains in order for most lamps to function optimally, without flashing or humming.

Please note: Due to technical restrictions, it is not possible to match the quality of industrial PLC filters. Refer to the FAQ on dimming at www.niko.eu/faq for more information on reducing PLC signals.

Meaning of the red indication LED

• The LED lights up
  •  the dimmer is connected correctly (when installing)
  • and the load is switched on.
• The LED flashes
  • malfunction; the dimmer is not connected correctly, overload, short-circuit incorrect setting. See Troubleshooting in §4 of this manual.

Permitted loads
The following table provides an overview of the maximum load that is permitted per lamp type at an ambient temperature up to 35°C.

Adjust the dimmer settings according to the type of lamp

You set the correct load with the DIP switches as follows.

• (*) These lamp profiles are equipped with boost function. This means that upon switching on, the lamp will briefly shine brightly before going to the desired dimming level (if the memory function has been activated).

Select profile for LED lamps
To select the right profile for the installed LED lamps, you proceed as follows:

1. Try out profiles LED 5 and LED 6, one after the other. If one of these profiles functions properly, go to § 3.10.
2. If not, try the profiles LED 1 and LED 2, one after the other. If one of these profiles functions properly, go to § 3.10.
3. If not, it means the LED lamps need a lot of energy to start up. In this case, choose the lamp profile LED 3, LED 4, LED 7 or LED 8. These profiles have a boost function ensuring that, when starting up, the lamps receive enough energy before going into the desired dimming level (with activated memory function).

We provide an example of the advantages and disadvantages of the latter two options below:

•  In certain cases the difference that can be reached in light output is limited

| When switched on, the lamp is bright for a moment if a low dimming level was selected
The dimmer switches off by itself. The red LED on the dimmer is flashing.| The protection against thermal overload (temperature is too high) and short circuits has been acti- vated.| Check if the lamp is dimmable. This is shown on the packaging by the following symbol:
---|---|---
Check whether the load is too high. When doing this, keep in mind the reactive power of ferro- magnetic transformers.
Check the temperature in the ca- binet (max 35°C) or create more distance between the dimmer and the adjoining module.
Check whether mixed loads have been used, and make sure that only one type of lamp load is in the lighting circuit.
The dimming profile is incorrect.| For dimmable LED lamps: test all lamp profiles one by one and choose the profile that works best. Dimmable LED lamps that require a boost function (do not start up at minimum dimming) can be controlled with lamp profiles LED 3, LED 4, LED 7, or

LED 8.

For incandescent lamps and halogen lamps with electronic transformers, choose lamp profile LED 1.

For halogen lamps with ferromag- netic transformers, choose lamp profile LED 2.

For dimmable economy lamps, choose a lamp profile with boost function: LED 3 or LED 4.

The lamp is flashing.| The lamp is not dimmable.| Check if the lamp is dimmable. This is shown on the packaging by the following symbol:
The minimal dimming level is set too low.| Lower the minimum dimming level or use a profile with boost function (LED 3, LED 4, LED 7 or

LED 8).

The dimming profile is incorrect.| Choose another profile and adjust the minimum dimming level.
There is a PLC malfunction.| Refer to the FAQ on dimming at www.niko.eu/faq
The lamp is not suitable.| Replace the lamp if it flashes during dimming the light up and down.
The dimmer is defective.| Replace the dimmer
The lamp cannot be switched off.| There is leakage current due to certain dimmable LED lamps or dimmable economy lamps with a low electrical load. Leakage current can also occur due to capacitive effects of long cabling.| Fit another lamp with a higher minimum electrical load. Or fit a LED compensator (09-016-10 or 310-0500x) over the lamp, bet- ween the switching wire and the neutral conductor.

Setting the minimum level
In order to reach the (optimal) maximum range for each lamp, the minimum level can be adjusted. See fig. 3.

TROUBLESHOOTING

USAGE WARNINGS

• PLC 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. In other words, all parts remain connected to the power even if the load (e.g., the light) is “off”.
• This appliance is not suitable for controlling motors.
