SERVICING THE AT10.1
46
Error
Code
Meaning Repair Procedure
E 04 internal memory
failure Any parameters that you set, such as Float or Equalize voltage, are
saved internally. The internal memory is tested on startup. If the
memory test fails,
E 04 appears on the front panel display. The error
may also appear if the controller was trying to write to the memory
while a power failure occured.
If an E 04 appears, try restarting the AT10.1 by turning the ac and dc
breakers off, then on. If the AT10.1 restarts normally, you must
reenter any changes you made to the factory settings (float voltage,
etc.).
If E 04 appears repeatedly, the internal memory has been damaged.
You must replace the control circuit board. See Section 3.6 for parts
ordering information.
E 05 not used This error code was formerly used to indicate a reverse battery
connection. It is not available in the AT10.1.
E 06 R4 or R14 is
defective, or
remote sense
wiring failure Locate R4 and R14 on the Gate Driver pc board (A11) on the back of
the front panel. Remove the wire harness plug from J18 and remove
A11 from the main control board (A1). Use an Ohmmeter to measure
the values of R4 and R14 (see table 3-1 for the correct value). If
either resistor is not within 1% of the specified value, the entire Gate
Driver pc board (A11) must be replaced.
If you are using remote sense wiring from the battery to the AT10.1,
the wiring may have failed. The usual failure is an open circuit; a
short circuit will usually be indicated by smoke or fire in the wiring.
The AT10.1 displays the error code if it detects this wiring failure.
You should respond to this problem quickly to be sure that the
AT10.1 regulates the output voltage properly.
Wire an annunciator
(e.g. buzzer) to the summary alarm relay contact (TB3) for remote
indication of any charger problem, or monitor the AT10.1 operation using
the optional DNP-3/MODBUS communications board
.
If you have a failure in remote sense wiring, the AT10.1 regulates its
output voltage locally until you correct the problem, see Sections 1.9.
The locally controlled voltage may not reflect the true requirements of
the battery.
When you complete the repair, restart the AT10.1 per Section 2.1.
E 07 DC breaker
open, or internal
failure If the dc breaker is open, open the ac breaker, then reclose the dc
and ac breakers. If the dc breaker trips again, see the
troubleshooting chart in Section 3.4.
If the dc breaker is closed, but you have an
E 07 display, check your
battery. If the battery is disconnected, and you then disconnect the
load, the AT10.1 may display an
E 07 code. Restart the AT10.1
according to Section 2.1.
If the battery and load are OK, see the troubleshooting chart in chart
in Section 3.4 for help in locating the problem.
