2.2. USING THE AT30 FRONT PANEL FEATURES
2.2.1. If the meter displays an error message
When you apply power to the AT30 for the first time, the micro-processor
control circuit performs a diagnostic check of the system. If it finds
anything wrong, it writes an error code to the display, such as
E 01
.
Below is a list of the error codes. See Section 3.2 for a full explanation of
each error code.
Error Code
Explanation
E 01
resistor R2 is open or defective
E 02
short circuit on dc output
E 03
high dc voltage shutdown has occurred
E 04
Internal memory failure
E 05
not used
E 06
failure in remote sense wiring
E 07
dc breaker is open, or internal or external
output wiring is defective
E 08
defective temperature compensation probe
E 09
misadjusted current limit
E 10
open internal feedback loop
E 11
not implemented at this time
E 12
defective internal thermostat
E 13
internal over-temperature
E 14
forced load sharing not working properly
A 02
equalize mode is inhibited
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 AT30 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.
