Universal Dimmer
Upon connection of the supply voltage, the microprocessor
integrated in the dimmer evaluates the characteristics of
the connected service load and decides whether phase-
angle or phase-section control is to be employed. During
this calibration process, the lighting installation switches on
for up to 2 seconds. During this time, the status display
lights up red and the device is blocked.
In order to ensure that the precise load is
recognised by the dimmer, this should
neither be operated with short circuit nor with
secondary open-circuit conventional
transformers when the supply voltage is
connected.
After the load has been determined, the colour of the
status display changes to green.
