ADJUSTABLE CHARGE TERMINATION SET-POINTS - (“Charge Set-Point”): Four different
charge termination voltage set-points are available with this switch.
The control is factory set at position B. To change the set-point, locate the adjustment switch
on the front panel. Using a slotted screwdriver, turn the switch until the slot is pointing at the
desired position.
If problems develop, refer to the "TROUBLE SHOOTING" section of this book.

LOW-VOLTAGE LOAD DISCONNECT (LVD) SETTINGS:
NO LVD - (“OFF”): - For an override of the load disconnect function, push the switch up.
No load disconnect will occur with the switch in the "OFF" position.
AUTOMATIC LVD - (“NORM”): - When the “Load Disconnect” switch is in the "NORM"
position, the load control circuit will operate automatically. Refer to the “OPERATION :
LOW-VOLTAGE DISCONNECT” section for a description of this operation. If a load
disconnect occurs, the loads will be automatically reconnected when the batteries
charge up to the Load Reconnect voltage, or they can be reconnected manually by
using the “RESET” position.
MANUAL RESET - (“RESET”): - For a temporary load reset, push the switch down. The
battery voltage must remain above the Load Disconnect voltage for the load to stay
connected after reset.
ADJUSTING LVD SET-POINTS - (“Load Disconnect Adjust”): The Load Disconnect and
Reconnect set-points are factory set as listed in the specifications section, and are adjustable.
To alter the voltage at which the load disconnect and reconnect occur, turn the adjustment pot
on the front of the unit labeled “Load Disconnect Adjust” clockwise to decrease and counter-
clockwise to increase (for the range of adjustment, refer to the specifications section: “Load
Disconnect Adjustment Range”). Both set-points will change, with the span value fixed.
NOTE : When adjusting this control, it is important to use the proper size screwdriver. Do not
force the adjustment beyond the end stops, it will damage the control.
If problems develop, refer to the "TROUBLE SHOOTING" section of this book.
