General Description - Gewiss GW 90 764 Handbuch

The KNX dimmer actuators for LEDs powered with continuous voltage (Vdc) - DIN rail
mounted, are devices for adjusting the brightness for max. 4 single colour LEDs or LED
RGB[W] strips and spotlights. They are available in two versions:
- CVD (constant voltage control) for controlling single colour or RGB[W] strips;
- CCD (constant current control) for controlling power LEDs (single colour or RGB[W]).
The dimmer actuators are powered by the BUS line and are equipped with 4 two-toned front
LEDs that indicate the status of the outputs, 4 front control button keys for testing the
outputs, 1 red LED for signalling any faults, 1 relay contact for controlling the network
voltage of the LED auxiliary power supply, 4 independent output channels.
The dimmer actuator is assembled on a DIN rail, inside electric boards or junction boxes.
The dimmer actuator is configured with the ETS software, to perform the following functions:
ON/OFF SWITCHING (*)
- Setting the degree of light intensity corresponding to the ON switching command
- Setting the delay for switch-on and switch-off
RGB[W] RELATIVE BRIGHTNESS CONTROL (*)
- Parameterisation of the maximum and minimum adjustment thresholds
- Parameterisation of the relative adjustment speeds between 0% and 50%, and between
50% and 100%
RGB[W] ABSOLUTE BRIGHTNESS CONTROL (*)
- Setting the mode for reaching the required light intensity (via a ramp or jump to that value)
- Parameterisation of the ramp adjustment speed 0% - 100%
SCENES (*)
- Memorising and activating 8 scenes (value 0 - 63)
- Enabling/disabling of scene learning from BUS
COLOUR SEQUENCES
- Execution of preconfigured colour sequences (e.g: strobe, rainbow, blinking, etc.)
- Setting of reproduction speeds, initial colour and number of repetitions
PRIORITY COMMAND (FORCING) (*)
- Setting the degree of light intensity with forcing ON activation
- Setting the forcing status upon BUS voltage reset
TIMED SWITCHOVER (STAIR RAISER LIGHT) (*)
- Parameterisation of light value during timing
- Setting the activation time
- Setting the pre-warning time
