Turn the switch on the front of the unit on to energize the outputs. The green ‘Output On’
indicator light will glow to indicate the proper operation of the unit.
OUTPUT ADJUSTMENT
The unit has an adjustment potentiometer to allow up to ±1.0V adjustment of the output
voltage. This potentiometer is accessed through a small hole in the front of the voltage
converter. As shipped from the factory, the unit is preset for a voltage of 13.6, 27.2, 36.3
or 54.4VDC. Reach in with a very small flat blade screwdriver to rotate the potentiometer.
Clockwise increases the output voltage and counter clockwise decreases it.
METERS
The meter shows simultaneous voltage and current. It features bright red LED readouts to
permit easy monitoring from many feet or meters away.
Operation
The dry contact output-fail relay is accessed through the small 3-connection terminal block at
the back of the converter. The user has a choice of using either the normally open or normally
closed contacts. To connect to the relay, connect one wire to the common (COM) terminal and
connect the other wire to either the normally open (NO) or the normally closed (NC) terminal.
