AC Applied

Self Test

Lights when AC power is applied to the charger. Turns off when AC power is removed from the charger.

Lights when a self diagnostic test begins. Turns off when the self diagnostic test completes. See Section 9.5 for details.

9.2.2 Main Display

The main display is a 4-digit alphanumeric display that communicates status information, charge cycle parameters, and fault codes to the user. With extra-large 1-inch characters, the display can be read from a significant distance. During a charge cycle, the user can press the Scroll button to select which real-time charge cycle parameter is shown on the display. Available parameters are current in amps

(XXXA), voltage in volts (XX.XV), amp-hours returned (XXXX) and time on charge in hours and minutes

(XX.XX). By default, the display toggles between the current in amps and voltage in volts. When a charge cycle is not in progress, the Voltage and Battery Type String is displayed.

Displays Description

xxVb Waiting for a battery to be connected to start a charge cycle. (See Voltage and

Battery Type String information below.)



Charge cycle completed successfully.

Waiting for a programmed delay, time of day, or blackout start time before starting



REST charge.

Manual stop was pressed to stop the charge cycle.

Charger is in the programmed cool down time after a completed charge cycle

Charger DC output is shut off for approximately 3 minutes as part of the multivoltage charging voltage detection routine. The output will start again automatically.





Self test is being performed.

The self test passed.

The self test failed.

A battery is connected, but AC power is not yet available to the main transformer, so the charge cycle cannot be started. If this message is constantly displayed, an issue exists in the AC path (AC contactor, AC fuses, etc).

Figure 9.2.2-1: 4-Digit Display Information

Voltage and Battery Type String

The profile voltage and battery type information will be used to create a display string.

The format will follow: xxVb.

Where: xx = voltage (12, 24, 36, or 48) or M for multiple voltage.

V = indicates VOLTS. b = battery type, where W = wet, S = sealed, O = opportunity charge, or M = more then one battery type exists among the multiple battery profiles.


1. 24VW is 24-Volt wet.

2. MVW is multiple voltages wet.

3. MVM is multiple voltages and multiple battery types.

9.3. LCD Display and Navigation Pad User Interface

The charger user interface includes a 2-line, 32-character LCD display and navigation pad. These features enable the user to view the charger status and extended charge cycle parameters, view and change charger settings, and reviewing the charge cycle history by navigating the menu system diagramed in Figure 9.3-1.

Figure 9.3-1: Menu System

Status messages are automatically displayed on the LCD. When a charge cycle is active, the first entry in the menu system, View Status, is automatically selected and the menu system is locked. When a charge cycle is not active, the Up and Down buttons on the navigation pad can be used to scroll through the menu items. An asterisk (*) denotes which menu item is currently active. Pressing the Select button or the Right button on the navigation pad opens the active menu item. The Left button on the navigation pad can be used to move back up the menu system. Figure 9.3-2 shows the navigation pad with the buttons labeled. www.douglasbattery.com
