10. ERROR CODE DESCRIPTIONS
As described in Function 12, error codes are shown
if a problem occurs which the charger recognizes. If
more than one error occurs, a short pause will be
taken between showing the error codes. To clear an
error code, see Function 17. If an error has been
cleared, but the problem still exists, the error will be
detected again after leaving the program or terminal
mode. An explanation of each error code is given
below:
1
IMPROPER OUTPUT
The charger is unable to reach either the set output
current or the set output voltage. It will also occur if
the input line voltage drops too low to maintain
proper output levels.
setting, line voltages and battery voltages before
clearing this error.
2
STUCK BUTTON
One of the buttons on the front of the charger is not
working properly or one was pushed too soon after
being powered up (wait 30 seconds). The charger
will display "222" for a few moments showing it
recognized a problem with one of the buttons. If the
button cannot be made to work, the charger needs
servicing.
3
INTERNAL
This occurs if the control module has an internal
problem. The charger needs servicing.

a probe is connected and is operating improperly. If

8
BATTERY OVER TEMPERATURE
This error occurs when the battery temperature
reaches 130°F. To prevent damage to the batteries,
the output of the charger is reduced until 135°F is
reached.
At 135°F, the output will stop until the
temperature decreases.
9
CHARGER OVER TEMPERATURE
This error occurs when the charger's temperature
reaches 150°F. At 150°F, the output will be reduced
to protect the charger from damage. When 165°F is
reached, the charger will stop until the temperature
decreases.
10
EXCESSIVE CABLE DROP
The battery voltage measured at the charger's
terminals has exceeded the voltage measured at the
batteries by 4 volts. This indicates there may be a
problem with the cables between the charger and
the batteries or between the batteries. The charger
can only measure this if sample hold is set to "0"
(Function 23).
11
BATTERY SENSE CABLE
On models 12/501 and 24/301, when the battery
sense is active and detects an improper output
voltage, this error will occur and sample hold will
switch to "0". This error also occurs if sample hold is
set to "2" without a battery sense cable connected.
12
PROGRAMMING LOST
If this occurs, the charger sensed one of the function
variables to be invalid and the charger will shut
down.
All of the functions will have to be
reprogrammed, and the charger then restarted.
