2.2. USING THE AT10.1 FRONT PANEL FEATURES
2.2.1. If the meter displays an error or status message
The AT10.1 microprocessor control circuit 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.
Code Explanation
E 01 resistor R2 open or defective
E 02 short circuit on dc output
E 03 high dc voltage shutdown occurrence
E 04 internal memory failure
E 06 remote sense wiring failure
E 07 dc breaker open, or dc output wiring defective
E 08 temperature compensation probe defective
E 09 current limit setting misadjusted
E 10 internal feedback loop open
E 12 defective internal thermostat
E 13 internal over-temperature occurrence
E 14 forced load sharing not working properly
A 01 manual equalize enabled for more than 24 hrs
A 02 equalize mode inhibited
A 04 voltmeter calibration inhibited w/tempco active
A 05 dc output at Current Limit setting
Codes E 05, 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 key to change the meter display mode. The digital
meter has four operating modes:
1. Alternating between output voltage and output current. When the
charger 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 Amps indicator lights.
4. Displaying equalize hours remaining only. The EQLZ HRS
REMAINING indicator lights. If the AT10.1 is not in a timed
equalize mode, the meter displays the full programmed equalize
time.
• When the charger starts initially, the meter alternates, showing output
voltage and output current. The DC Volts and DC Amps indicators light
alternately to indicate what is being displayed.
