*Configuration Code displayed on charger label.
8.4.8.
Reverse Polarity
Indicates battery is connected backwards. Charger output is disabled until the condition is
corrected. Activates flashing red/yellow DC LED. When this alarm is assigned to a relay contact
REVERSE POLARITY will cause the assigned relay to change to the Failed state after the time delay.
8.4.9.
Incompatible Battery
Indicates charger is connected to an incompatible battery. The charger operates for
approximately 5 minutes while observing behavior of the DC voltage. If DC voltage behavior is
normal the charger will continue charging. If DC voltage behavior is abnormal, as is typical with a
battery voltage mismatch, the charger will shut down and lock off after approximately five
minutes. Activates flashing yellow DC LED. When this alarm is assigned to a relay contact
INCOMPATIBLE BATTERY will cause the assigned relay to change to the Failed state after the time
delay. After correcting mismatched condition cycle power to reset the charger and begin
operation. See section
for charging a very low or zero-volt battery, when this safety feature
would be a nuisance.
8.4.10.
Invalid Settings
Indicates settings are not valid. Output is disabled until the condition is corrected. Activates
alternating flashing yellow AC and DC LEDs. When this alarm is assigned to a relay contact
INVALID SETTINGS will cause the assigned relay to change to the Failed state after the time delay.
8.4.11.
Fan Fail
Indicates a problem with one of more of the fans in a module. When this alarm is assigned to a
relay contact FAN FAIL will cause the assigned relay to change to the Failed state after the time
delay.
8.4.12.
SENSbus Inactive
Indicates the charger is not communicating on SENSbus either when load sharing and/or remote
accessories are connected. When this alarm is assigned to a relay contact SENSBUS INACTIVE will
cause the assigned relay to change to the Failed state after the time delay.
8.4.13.
Thermal Fold Back
Indicates output power has been reduced to protect from over-heating. The charger will not be
able to produce full output until the ambient temperature is lowered. When this alarm is assigned
to a relay contact THERMAL FOLDBACK will cause the assigned relay to change to the Failed state
after the time delay.
8.4.14.
Temperature Probe Fault
Indicates disabled or failed remote temperature sensor. This alarm is only available when a
remote battery temperature sensor is installed with the optional remote battery monitor. When
the temperature probe sensor is shorted temperature compensation is turned OFF. When this
alarm is assigned to a relay contact TEMPERATURE PROBE FAULT will cause the assigned relay to
change to the Failed state after the time delay.
8.4.15.
Current Limiting
Indicates the charger is operating at maximum allowable output, either the maximum current
