Depending on the type of load connected, the single and the dual
universal dimming actuator operate either in the phase cut-on or
the phase cut-off mode and permit switching and dimming of
incandescent lamps, HV-halogen lamps and LV halogen lamps via
conventional transformers and Berker Tronic transformers.
After the installation and connection to the mains, the dimming
actuator detects and identifies the load automatically.
With resistive loads (incandescent and HV halogen lamps), the
identification is indicated by short flickering of the lamp and lasts
between 1 to 10 seconds depending on mains conditions.
Telegrams received during the identification are executed when the
procedure is terminated.
Mains failures of more than 0.7 seconds cause the dimming actuator
to shut off. On restoration of the supply, the actuator repeats the
load detection procedure.
Function Short-circuit protection
Each output has its own short-circuit protection.
In the event of a short-circuit in the identification phase, the actuator
must re-identify the load after elimination of the short-circuit.
Phase cut-off operation (capacitive load, resistive load):
Shutoff of the output concerned with automatic restart after
elimination of the short-circuit within 7 seconds. Thereafter, the
actuator is shut off permanently until the next ON-telegram is
received.
Phase cut-on operation (inductive load):
Shutoff of the output with automatic restart after elimination of the
short-circuit within 100 ms. Thereafter, the actuator is shut off
permanently until the next ON-telegram is received.
