Product and Applications Description
The Switch-/Dimming Actuator is a KNX device for control-
ling up to two groups (channels) of lamps via the
DC 0/1 -10 V control terminal of dimmable electronic ballasts
(ECGs). In addition there is per channel a switching contact
for direct switching on/off of the connected lamps.
The device is installed into or attached to a 4 x 4 inch junc-
tion box. The bus is connected via a bus terminal block. The
actuator electronics are supplied via the bus voltage.
Each channel of the Switch-/Dimming Actuator can control
several dimmable electronic ballasts. Their number is limited
by the switching capacity and by the control power. If the
on/off function is not used via the switching contact of the
Switch-/Dimming Actuator, the number of controllable ECGs
is only dependent on the load of the DC 1-10 V control volt-
age. This might allow controlling a larger number of ECGs
(see Technical Specifications below).
Various functions can be configured per channel such as for
switching on/off lamps, dimming up / down or setting a par-
ticular dimming level.
With the ETS (Engineering Tool Software) the application
program is selected, its parameters and addresses are as-
signed appropriately and downloaded
Switch/Dimming Actuator.
Amongst others, the application program includes an op-
tional counter for switching cycles and operating hours with
threshold monitoring for each output and an integrated 8-bit
scene control for incorporating the output into up to 8
scenes.
Each output of the actuator may be set to one of the follow-
ing operating modes:
- Normal operation
- Timer operation
