SERVICING THE AT10.1

Error
Code
Meaning Repair Procedure
E 08 defective
temperature
compensation
probe If a temperature compensation probe is connected to the AT10.1, the
control circuit detects the probe on startup, and uses the temperature
measured by the probe to control the output voltage of the AT10.1. To
understand temperature compensation, see Section 1.11.
If the temperature compensation probe, or the wiring that connects it to
the AT10.1, fails during normal operation, the AT10.1 detects the failure,
and shows
E 08 on the front panel meter.
Disconnect the wiring from the probe, and measure the resistance of the
probe with an Ohmmeter. The resistance should be approximately
10,000 Ohms at normal room temperature (77° F / 25° C). If the probe
reads open or shorted, it needs to be replaced.
If the probe checks good, examine the wiring between the probe and the
AT10.1. Also check the connection of the cable to the control circuit
board on the back of the front panel. If the wiring is OK, then the probe
needs to be replaced. Once you have replaced the probe, you must
restart the AT10.1 to activate temperature compensation.
E 09 misadjusted
current limit The output current limit is set at the factory to 110% of the rated output
current (e.g. for a 50 Adc charger, the current limit is set to 55 Adc). You
can adjust the current limit downward to as low as 50% of the output
current, if you have special requirements such as limited ac power
available. You should do this only if the normal dc load on the system is
smaller than the current limit.
If you do reduce the current limit setting below 100% of rated current,
your connected load might require more current than the AT10.1 can
deliver. If this happens, the battery will not charge properly. If this
occurs, the front panel displays the error code
E 09. You should increase
the current limit setting so that the AT10.1 can supply all the current
required by the load, and still charge the battery. The current limit should
be set to at least 5% greater than the maximum continuous dc load
current.
NOTE: The common alarm relay is not set for this condition.
E 10
open internal
feedback loop A redundant internal feedback loop (control loop) is provided as
redundancy, to increase reliability when remote sensing is used. If there
is a problem with the internal loop wiring, the AT10.1 will display
E 10.
Check the internal wiring in the signal harness, especially wire # 50. Also
check the harness connector on the main control circuit board.
E 14 forced load
sharing not
working
properly See Appendix F on page 92. Verify both AT10.1s are functioning
properly. Ensure that the forced load sharing interconnection cable
assembly is not broken, is properly installed, and that the connector for
the Secondary charger has the jumper as described. Ensure that both
AT10.1s are connected to the same ac supply and that source phase
rotation is the same for both AT10.1s.
A 01 manual equalize
enabled for
more than 24
hours If AT10.1 was accidentally left in manual equalize mode, switch unit back
to float, manual equalize timer, or auto-equalize timer mode.
A 02
equalize mode
inhibited If you set the equalize timer to zero hours, the equalize mode is inhibited.
When you try to put the AT10.1 into equalize mode with a front panel
control, the display shows the message
A 02. If you want to enable the
equalize mode, set the equalize timer to 1 or more hours.
