Dimming Operation Mode

The device is a types of universal dimming actuator and detects connected loads automatically. Load detection determines whether an inductive, capacitive or ohmic load is connected. However, there is also the option of selecting an alternative operating mode for special LED or energy-saving lamps (ESL/CFL) using the ETS parameters.

In order to ensure that different loads are adjusted optimally, further settings can be altered for each channel. You can adapt the starting behavior on switching on to the ESL/CFL ignition process. (Always Start at 50% Brightness (ESL/CFL))

The dimming range can generally be adapted individually for each channel for all loads (Dimming Range).

For information on special dimming curves for LED, halogen and incandescent lamps or user-defined, see Section Dimming Curve.

In this section you will learn about automatic load detection and the alternative dimming operation mode "Leading edge phase LED, ESL/CFL (RL-LED)", and find out which combinations of different loads are permitted.

The following dimming operating modes can be selected:

• RC operating mode = trailing edge phase (automatic)

• RL operating mode = leading edge phase (automatic)

• RL-LED operating mode = leading edge phase LED, ESL/CFL (can be set via ETS)

Load detection is only possible if the voltage and frequency are within the permissible range and there is no short circuit or overload.
