Min Level

“Min Level” sets a low level threshold. If the
control signal is below this level, the dimmer will be off.

Min Level
3.13.3
Max Level
Dimmer channels can have a maximum level.
“Max Level” sets the level of the dimmer output
when its control signal is at maximum. For example, setting this value to 90% will extend the
life of an incandescent lamp as it never operates on full voltage or setting it to 50% provides
115 volt output.
Note: The actual output voltage of the dimmer channel is dependent upon the dimmer curve.
LSC recommends that you measure the output voltage (with a 240 volt load connected) to
determine the “Max” level setting you require for a specific maximum voltage. This procedure
should only be carried out by suitably qualified personnel.
