Operation in Constant Current Mode
1.
2.
3.
Set switch SW3/5 to the “TRIG” position. This will illuminate the green indicator of D6
indicating the driver in triggered mode.
Set the dip switch SW1 to be in “Always ON” mode. The settings for this are included in table
2.
Use the on board Potentiometer R15 to adjust the current to the LED. (See figure 3 for details)

Operation in Triggered Mode
1.
2.
3.
Set the maximum desired current to the LED by following step 4.1
Using the DIP switch SW1 select a preprogrammed time interval as shown in Table2 or select
the “gated” function if the time interval will be set by an external source.
Attach an external source capable of providing between 5 – 10 V to J6 as the trigger
mechanism.
a.
b.
If a preprogrammed time interval was selected, the LED will light up for that time
period every time the driver board sees a voltage on J6 between 5 – 10V.
If the “gated” function was selected, the LED will light up for as long as there is a
voltage applied between 5 – 10V on J6.
