Zamel Ledix WDN-01 Quick Manual page 2

DESCRIPTION
The WDN-01 device is used to switch on or switch off the light by means of a touch. The switch has
a sensor with 1,5 m long wire, which is connected to conductive components of lighting fittings. The
WDN-01 switch is supplied with 10 ÷ 14 V DC. It has a PWM output for a direct connection of LED diodes
and the output of NO free relay with a maximum load of 5 A. It is possible to switch on/switch off any
receiver (conventional light bulbs, halogens) by means of the relay output. Using the PWM output the
brightening/dimming function is also available, apart from switching on / switching off. The relay output
operates in parallel way with the PWM output. WDN-01 has small casing dimensions and is designed
for surface mounting. It is recommended to use WDN-01 to control lighting in the kitchen and bath-
room furniture. The device can also be installed on flammable materials, e.g. wood, furniture boards
and plasterboard.
The switch features:
• brightening / dimming function,
• low power consumption during stand-by mode (0,25 W) - the device is suitable for a continuos opera-
tion mode,
• PWM output for a direct connection of LED diodes,
• output of NO free relay with a maximum load of 5 A,
• automatic calibration process referring to the change of a sensor's connection place or the touch
surface.

MOUNTING
CAUTION! The device is designed for single-phase installation and must be installed in accord-
ance with standards valid in a particular country. Installation, connection and control should be
carried out by a qualified electrician staff, who act in accordance with the service manual and the
device functions.
1. Disconnect power supply by the phase fuse, the circuit-breaker or the switch-disconnector combined
to the proper circuit.
2. Check if there is no voltage on connection cables by means of a special measure equipment.
3. Connect the power supply to 230 V AC voltage.
4. Connect cables to proper terminal clamps of WDN-01 according to connection diagram.
5. Mount the switch and the sensor on their final place.
6. Switch on the power supply from the mains and check proper functioning of the device.
IMPORTANT:
If during the use of WDN-01 switch there is a need to change the sensor's connection place, it
can be done without disconnecting the power supply. However it should be remembered, that in
each case after such an operation it is necessary to wait at least 10 seconds to perform the switch
automatic calibration process.

CAUTIONS
• The sensor should be connected to the conductive elements such as metal casing of lighting fittings,
grips, handles, etc. These elements must be electrically insulated.
• It is recommended that the surface to which the sensor is connected is as small as possible (it should
not exceed 25 dm2). If the surface increases more than 5 dm2 the difference in the touch sensitivity
can be observed.
• Switching on / switching off the circuits connected to the output terminals of the WDN-01 switch is re-
alised by a short touch of the item to which the sensor is connected. Additionally in case of LED diode
lighting source (connected to the PWM output) brightening / dimming is possible and it is realised by
a longer pressing the element to which the sensor is connected.
• The sensor's cable can be extended up to a maximum of 3 m with a minimum cross-section of 1 mm2.
• It is recommended to use LEDIX power supplies (ZNP, ZNN, ZNM series) to supply the WDN-01 switch
and LED load connected to the PWM output.
• It is necessary that the power supply is properly adjusted (the power should be higher of about 5 to
10%) to the total power consumed by the loading. It applies to loads powered from the same power
supply as the WDN-01 switch.
• The relay output operates always together with PWM output (the relay is switched on in the moment
of PWM output control).
• The adjustment level of luminous flux intensity (PWM output) is remembered by the touch switch
(subsequent modulation switch on / switch off is performed to the remembered level).
