The DC output current is limited to provide for complete protection The current limiting feature allows for the unit to carry
overloads and limits the output to a miximum of 140% of the rated output.
Power failure contacts are provided for remote power failure indication. One normally open and one normally closed
contact are connected to three terminals on the terminal board for connection to the remote alarm system.
The charger is factory tested and preset so that no field adjustments are necessary. Potentiometer(s) are provided for
adjusting the float and equalizing voltages to the required levels. Should further field adjustments be necessary the float
voltage may be adjusted by moving the red slider band on the voltage divided resistor RV1. Moving the slider toward the
green slider or toward RV2 raises the taper and shutdown point and moving the slider in the opposite direction lowers the
point of shutdown. The green slider band is the equalizing voltage adjustment and may be adjusted in the same manner
as the float slider. On A11B and A12B units the red and green adjustment slider bands are on different resistors (RV1,
RV3).
