Once the assembly completed, you still need to set the dimmer for your particular application. Use an adjust-
ment voltage of 0 to 5 (or to 12V max). You can now wire the print according to the connection diagram (see
page 13).

Connect the supply voltage for a brief instant. Upon activation of the device, LD1(green LED) & LD2(red
LED) briefly flash together during the self-test. LD1 will flash briefly if there are no problems: 1 x in case of a
mains frequency of 50Hz and 2 x for 60Hz. There is a problem if the red LED remains lit (see error mes-
sages).

Turn RV1 fully counterclockwise and turn RV2 fully clockwise

Set the control voltage to 0 VDC

Apply AC power.

Adjust RV1 (minimum level) until LD1 (green) starts flashing rapidly

Trim RV1 just below the bulb ignition threshold

Set your max. control voltage e.g. 10 VDC

Adjust RV2 (maximum level) until LD1 (green) burns steadily

The circuit is now ready for use
