Preliminary Operating Instructions 28 of 62 AIP SERVICE NUMBER 1-800-863-3364
10.2.1 LIQUID CRYSTAL DISPLAY (LCD)
This is used to display DC Voltage and DC Current, fault identification, charger status information
and menu information.
10.2.2 “HOLD TO EQUALIZE” BUTTON (LARGE SQUARE BUTTON)
This is used to change from FLOAT mode to a manually started EQUALIZE mode. To manually
activate an EQUALIZE mode, push and hold about 6 seconds until the EQUALIZE LED
illuminates. The same button can be used to manually stop an equalize cycle and return to
FLOAT mode.
10.2.3 ARROW BUTTONS
The four Arrow buttons allow the user to go UP, DOWN, LEFT, and RIGHT in the menus. They
are used to view and change the different menus, display modes, and set point values.
10.2.4 GREEN “AC ON” LED
This LED will be illuminated whenever the charger has AC input power connected to it and the
AC circuit breaker is closed, (in the ON position).
10.2.5 GREEN “DC ON” LED
This LED will be illuminated whenever the DC circuit breaker is closed, (in the ON position) and
the charger detects DC voltage. This voltage can be the charger capacitor or battery voltage.
10.2.6 YELLOW “FLOAT” LED
This LED will be illuminated whenever the charger has AC or DC voltage and it is in the FLOAT
mode.
10.2.7 RED “EQUALIZE” LED
This LED will be illuminated whenever the charger has AC or DC voltage and it is in an
EQUALIZE mode.
10.2.8 BUTTON LOCKOUT JUMPER CONNECTOR
This allows the buttons to be locked out for security purposes. The connector is located on the
top left edge of the control circuit board when looking at the back of the board. The buttons
enabled jumper position is located on the top two pins (pins 1-2) of the J2 connector. If the
jumper is removed or put on the bottom two pins of J2 (pins 2-3) of the connector, the buttons will
be disabled and not allow any changes. (Shown in FIGURE 10.2)
10.2.9 BEEPER
This is designed to beep each time a button is pushed, signifying a button press except when the
button lockout feature is being used. It also beeps when the charger changes charging modes,
and beeps a tune on control board initialization.
11. CONTROL BOARD OPERATION
The Control Board operation will be explained in the following sections. These sections will explain the various
display modes, how to view or change information, and menu descriptions.
11.1 DEFAULT DISPLAY MODES
The charger’s “DC Voltage and DC Current” values are continuously displayed when there are no fault
codes and the charger is in FLOAT mode.
If there are faults, the display will toggle between the “DC Voltage and DC Current” and the Fault codes.
If in Manual/Manual Equalize mode and an Equalize Charge is started, the display will toggle between
the “DC Voltage and DC Current”, any Fault Codes, and “Manual Eqlz” (manual equalize cycle).
In any other equalize mode, the display will toggle between the “DC Voltage and DC Current”, any Fault
Codes, and the number of hours left of the equalize charge.
