General information

The FD3 U2E wireless universal pushbutton dimmer can dim a wide variety of lamps (LED, CFL, incandescent, LV halogen with electronic or wound transformer, HV halogen).

Along with automatic detection of wound transformers

(“Auto” dimming mode), the dimming mode can be set manually to forward or reverse phase control if necessary

(especially for lamps with electronic ballasts or electronic transformers). A special CFL dimming mode additionally provides an ignition and warm-up delay for compact fluorescent lamps (“energy-saving lamps”)

The compact dimensions of the FD3 U2E allow it be installed in electrical boxes behind a button switch from any desired product line, making it equally suitable for new installations as well as for maintenance-free replacement of existing or defective rotary or button dimmers.

Operation

A short button press toggles the lamp; a long press increases or reduces the brightness.

Functions

“Slumber” function (e.g. as an aid to help children fall asleep)

When this function is activated by dimming the lamp, the light level is dimmed down very slowly, with a duration that depends on the brightness at the start of dimming (duration from maximum brightness: 60 min.).

“Discreet dim in” function

In response to a long button press when the lamp is off, the dimmer switches on and dims up from the minimum brightness.

„Sync“ function

If several dimmers are controlled by a single button, they may become unsynchronised because the button command

(toggle) is not unambiguous.

Synchronisation is achieved by holding the button pressed long enough (approximately 10 s) for all dimmers to dim down to minimum brightness and then stop at maximum brightness (maximum level).

Installation

The FD3 U2E dimmer has a neutral line connection, so the lower load limit is 0VA. However, the dimmer must be operated without a neutral connection with (HV) incandescent lamp loads over 100W to avoid EMC problems. In this case the neutral terminal is jumpered to the load output. This has no effect on operation.

Standard connection

For dimmable LED, CFL and LV halogen lamps (with electronic or wound transformers) up to the maximum rated load, and for HV halogen and incandescent lamps up to 100W

Connection without neutral line

For HV halogen and incandescent lamps over 100W

1. Setting the dimming mode

Set the “Dimmart” control to a dimming mode suitable for the lamp (see table)

All suitable dimmable lamps can usually be operated in dimming mode 3 (Automatic).

Exceptions:

- Dimming mode 5 must be selected for lamps with wound transformers in a circuit with an automatic demand switch (use with wireless operation is not practical).

- Dimming mode 2 (or if appropriate mode 4) must be selected for CFLs (compact fluorescent lamps) which require an igniti on and warm-up time.

Reverse phase control with CFL mode. For dimmable CFLs which require an ignition and

In this mode, almost all loads are dimmed with reverse phase control, switching automatically to forward phase control only for wound transformers

Not suitable for lamps with wound transformers that are located in a circuit with an automatic demand switch - use dimming mode 5 in this case.

Forward phase control with CFL mode. For dimmable CFLs which require an ignition and warm-up time, and when dimming mode 2 does not provide smooth dimming.

Forward phase control. For dimming lamps with wound transformers that are located in a circuit with an automatic demand switch

CFL mode (dimming modes 2 and 4)

Most CFLs need full mains voltage for ignition. For this reason, this mode provides an ignition phase at half brightness before adjusting to the last (saved) brightness level. A warm-up phase with elevated minimum brightness is also provided because most CFLs have significantly reduced minimum dimming capability (without going out) when cold. The minimum brightness is gradually reduced to the normal value during the warm-up phase. The warm-up time depends on the off time, so the full warm-up time (max. 1 minute) is only used when the lamp has been off for an extended time. If a CFL is switched off at very low brightness and then switched on again when cold, the previous minimum brightness will be attained only after the warmup phase.

Automatic detection of wound transformers (dimming mode 3)

Wound transformers must be dimmed with forward phase control because reverse phase control generates inductive reverse voltages that can destroy the dimmer if it does not detect them and switch off on time.

In this dimming mode the dimmer automatically changes to forward phase control after being switched on as soon as overvoltages (not yet dangerous) are detected. This setting is retained until loss of mains voltage. This dimming mode is not suitable for use with automatic demand switches because the mains voltage is always disconnected after the lights are switched off.

2. Setting the minimum brightness

The minimum brightness should be set depending on the lamp so that the on state of the lamp can still be recognised at minimum brightness.

Switch on the dimmer and dim down as far as possible. Then set the minimum brightness to the desired level with the “Min.Hell.” control.

3. Setting the operating mode

Various special functions can be activated or combined using the operating mode setting.

4. Configuring wireless transmitters

The FD3 U2E has a wired control input (terminal 1) and a “wireless input”.

In its default configuration, the FD3 U2E already responds to button 1 / channel 1 from transmitters that are also configured with their default settings (address: DIP switches 1-8 in position “-”, level “A”, channel 1). The dimmer can already be switched on/off (short push) or up/down dimmed (long push) using button 1 on the transmitter. Similarly, a wired button on terminal 1 may also be used for switching and dimming (as described above).

You can find an overview of the default settings in Section 5.

Configuration process:

1) Press the Prog button briefly → LED lights up

2) Press the desired button on the wireless transmitter → LED goes out

5. Default settings

The FD3 U2E is configured with the default settings when it is delivered. The following settings are pre-defined in this configuration:

Input 1 Function:

Button 1 of a wireless transmitter with default settings dimming

Function: Toggling and dimming

Restore default settings:

Press and hold the Prog button for 10s until the LED flashes 5 times.

Ambient conditions and troubleshooting

Allowable load: The efficiency of wound transformers and electronic loads (LEDs, CFLs and electronic transformers) must be taken into account. The (primary) VA value is the critical parameter for the dimmer. Electronic loads must be approved by the manufacturer for dimming with forward or reverse phase control dimmers.

The dimmer heats up during operation, depending on the connected load. The connected load must be reduced if this heat cannot be dissipated adequately. Do not mount dimmers close to heat sources.

LED status display:

Info

The LED is lit red in the on state (going out briefly during the on/off ramp, going out every 1s during Slumber mode, and going out every 2s during the CFL warm-up phase). If a valid radio signal is received, it is (in addition) lit green. When input 1 receives a signal, the LED flickers green.

If a fault occurs, it displays a fault code.

General information:

Lamps approved for the same dimming mode can usually be used together. Incandescent lamps may always be operated in parallel. However, functional impairments occur fairly often when electronic loads from different manufacturers are operated in parallel, due to mutual interference of manufacturer-specific ballasts and/or electronic transformers. Wound transformers may not be combined with electronic loads. The dimmer is designed to work with as many different types of lamps as possible. However, it is not possible to guarantee troublefree operation of every dimmable lamp with the dimmer, since this can be affected by the design or construction of the lamp ballast or transformer. Flickering or erratic dimming in the low brightness range with LED lamps and CFLs is usually due to the lamp being designed for higher minimum input power. We recommend raising the minimum brightness setting in such cases. Ripple control signals from electricity plants can lead to perceptible flickering of the lighting. The magnitude of this effect varies from one region to the next.
