Dimming actuator
Product characteristics
– Automatic or manual selection of the dimming principle suitable for the load
– Protected against no-load, short-circuit and overheating
– Signal in the event of a short-circuit
– Outputs can be operated manually
– Feedback of the switching position and the dimming value
– Parameterisable switch-on and dimming behaviour
– Time functions: switch-on delay, switch-off delay, staircase lighting timer with run-on time
– Light scene operation
– Disabling of individual outputs manually or by bus
– Status indicator of the outputs via LED
– Operating hours counter
– Mains failure longer than approx. 5 seconds leads to switch-off of the dimming actuator.
Depending on the parameter setting, the connected load is calibrated after resumption of
power supply.
– Power extension possible by means of power boosters.
Delivery state: Construction site mode, outputs can be operated using button field.
Delivery state of the dimming actuator 1-gang: Dimming operation.
Flickering of the connected lamps due to undershoot of the specified minimum load or
through centralised pulses from the power stations. This does not represent any defect in
the device.
Only dimming actuator 4-gang:
– Increase in output power possible through parallel switching of multiple outputs
