ADJUSTABLE CHARGE TERMINATION SET-POINTS (“CHARGE SET-POINT
SELECT”): Four different charge termination voltage set-points are available with
this switch.

CONTROLLER SWITCH POSITION
VOLTAGE A B C D
12 VOLT 15.3 14.8 14.3 13.8
24 VOLT 30.6 29.6 28.6 27.6
36 VOLT 45.9 44.4 42.9 41.4
48 VOLT 61.2 59.2 57.2 55.2
The controller 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 SETTINGS:
NO LVD: - For an override of the load disconnect function, push the switch up.
No load disconnect will occur with the switch in the "NO LVD" position.
AUTO LVD: - When the “Load Disconnect” switch is in the "AUTO" 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 with the “Load Disconnect” switch.
MANUAL RESET: - For a temporary 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 controller, it is important to use the proper size
screwdriver. Do not force the adjustment beyond the end stops, it will damage the
controller.
