OPERATING THE AT30

2.2. USING THE AT30 FRONT PANEL FEATURES

2.2.1. If the meter displays an error or status message
The AT30 microprocessor control circuitry performs diagnostic checks of
the battery charger during system start-up, then continuously during
operation. If it detects a failure or special status, an intermittent code will
appear on the front instrument panel, displayed between dc output values.
The following table is a list of these error (E ##) and status (A ##) codes.

Codes E 05, E 09, E 11, and A 03 are not used. See Section 3.2 on page
45 for a full explanation of each code.

2.2.2. Selecting the meter mode

• Press the
METER MODE
meter has four operating modes:
1. Alternating between output voltage and output current. When the
AT30 is in a timed equalize mode, the meter alternates between
output voltage, output current, and equalize hours remaining.
2. Displaying output voltage only. The DC Volts indicator lights.
3. Displaying output current only. The DC Amperes indicator lights.
4. Displaying equalize hours remaining only. The EQLZ HRS
REMAINING indicator lights. If the AT30 is not in a timed equalize
mode, the meter displays the full programmed equalize time.
• When the AT30 starts initially, the meter alternates, displaying output
voltage and output current. The DC Volts and DC Amperes indicators
light alternately to indicate what is being displayed.
