Description
The dimmer detects what type of load is
connected and automatically selects the
appropriate dimming strategy (leading edge
or trailing edge).
Trailing edge phase control for resistive and
capacitive loads (LED lamps, incandescent
lamps, halogen high-voltage lamps, etc.).
For electronic transformers/power units
designated for use with RC mode dimmers
(trailing edge phase ctrl.).
Note:
When selecting RC mode, a load detection
will always be performed as a precaution.
This should prevent the dimmer from being
damaged (e.g. wound transformer) when an
L-load is connected.
The RC mode (trailing edge control) is
actually only used when no
L-load is detected.
Leading edge phase control for inductive
loads, e.g. wound transformers, but also
leading edge LED lamps.
Not suitable for electronic transformers, can
lead to a dimmer overload.
Special mode for fans, with configurable
start-up time (see below).
Only for LED lamps that cannot be dimmed
down at 100% (trailing edge control).
Do not use.
Only with Load selection = fan.
Time for which the fan must be controlled
with full voltage, until it has reached a
specific speed.
Minimum dimming value for all dimming
processes (except 0%).
Any values (switch-on dimming value,
response to bus failure, etc.) which are
below this threshold are increased to the
minimum dimming value.
