light will go off, and if set to 3-stage charging the voltage will drop to the float level. You may
check this voltage at the output terminals of the unit with a good digital voltmeter. As shipped
from the factory, the unit is preset for a float voltage of 13.6, 27.2 or 54.4 VDC, which is gener-
ally recommended for lead-acid batteries. If you wish to adjust this voltage, remove the cover
plate (secured by 2 screws) to expose the Output Adjust potentiometer. Reach in with a very
small flat blade screwdriver to rotate the potentiometer. Please note that this adjusts both
the float and absorption voltages at the same time. Clockwise increases the output voltage
and counter clockwise decreases it. When you are done, replace the cover plate and securely
tighten the screws. It is advisable to check with the battery manufacturer before changing the
float voltage.
Meters
A high quality digital meter can be added to the voltage converter (factory installed only). The
meter shows simultaneous voltage and current on either of the two output terminals. A toggle
switch permits selection between the output terminals. The meter features bright red LED
readouts to permit easy monitoring from many feet or meters away.
BATTERY TEMPERATURE SENSORS
Up to 2 battery temperature sensors can be connected to the charger to allow temperature
compensation of the battery charging voltage (1 is supplied with the unit). If only the 1 sensor
is used, it MUST be plugged into the ‘BATT 1’ connection on the side of the unit. If no sensor
is used, the charger will default to standard output voltage.
For installation isnstructions of the temperature sensor, please see the section entitled
