ground. On the 27 pin CJ pins 1 – 24 are channels 1 – 24, pin 25 is the 28 volt DC
supply and pins 26 and 27 common.
With your volt meter’s negative lead connected to the controller’s common pin and the
positive lead connected to channel number one, you raise all channels to maximum.
With all channels up you adjust the “max” trim to the desired level, factory adjustment is
10 volts.
To adjust the minimum voltage you bring channel number one down. (All other channels
must remain at maximum output) With the screwdriver in the “min” pot you turn it
counterclockwise to the near zero position.
*NOTE: Once the trim has been adjusted it does not need to be readjusted unless
another brand of dimmers have been introduced with different input control.
