Anti-panic function
If you open the contact between the two terminals, the dimming function
overloads and the installed load/loads illuminate with maximum power.
You need this function especially in emergency situations. With removing
the bridge, the dimmer goes to maximum load and does not react to standard commands. If you do not use this
function, you have to keep the bridge between the terminals closed. The dimmer works in the standard mode
then.

configuration selected:
SLAVE Master-Slave Mode
Potentiometer (intern or extern)
MEM Pushbutton operation – Memory function
NO MEM Pushbutton operation – No memory function

additional safety function in case of power failure
0-10V Signal 0 - 10V
Protection against over heat
Protection against over heat switches off the lamps.
Note: If the dimmer is switched off due to over heat protection, please try to:
Reduce the output load.
Install the dimmer inside an electric cabinet with forced ventilation or without other heat sources,
or place it in the lower part of the cabinet, where the accumulation of heat may be lower.
