The settings of the dimmer module are determined by placing a shunt (=jumper) over pins 1-2 or 2-3 of JP1,
2 and 3 (see figure 1.0). The operation of the device becomes unstable if the jumpers are not mounted.
JP1 – Memory function:
The last used luminous intensity is stored in the memory if this function is activated.
1-2: Memory function is deactivated.
or
2-3: Memory function is activated.
JP2 – Safe min. luminous intensity:
This function is designed to make sure a lamp doesn't burn at too low a luminous intensity for too long. This
function offers two distinct advantages: first of all, the life of a halogen bulb is not shortened unnecessarily
because it's working at too low a temperature. Furthermore, it doesn't really matter if a lamp escapes your notice
because of its limited luminous intensity. The lamp will be extinguished automatically after a certain time.
1-2: This function is deactivated.
or
2-3: This function is activated.
