Preliminary Operating Instructions 34 of 62 AIP SERVICE NUMBER 1-800-863-3364
AC Hi Armed or Disarmed
“AC Hi” stands for AC voltage input high. This fault occurs if the AC input voltage is higher than
the nominal AC input voltage for the charger by approximately 10% or more. This menu allows
the user to arm or disarm the “Hi AC” fault code and optional ALARM I/O Relay board contacts.
AC Lo Armed or Disarmed
“AC Lo” stands for AC voltage input low. This fault occurs if the AC input voltage is lower than the
nominal AC input voltage for the charger by approximately 10% or more. This menu allows the
user to arm or disarm the “Lo AC” fault code and optional ALARM I/O Relay board contacts.
DC Hi Armed or Disarmed
“DC Hi” stands for DC voltage output high. This fault occurs if the DC output voltage is higher
than the value set in the “DC Hi set point” menu. This menu allows the user to arm or disarm the
“Hi DC” fault code and optional ALARM I/O Relay board contacts.
DC Lo Armed or Disarmed
“DC Lo” stands for DC voltage output low. This fault occurs if the DC output voltage is lower than
the value set in the “DC Lo set point” menu. This menu allows the user to arm or disarm the “Lo
DC” fault code and optional ALARM I/O Relay board contacts.
DCFail Armed or Disarmed
“DCFail” stands for DC voltage failure. This fault is caused by the DC output circuit breaker being
open or in the OFF position or the charger detecting no DC voltage. This menu allows the user to
arm or disarm the “DCFail” fault code on the optional ALARM I/O Relay board contacts. The
“DCFail” fault does not show as a fault on the Control Board display. The “DC ON” LED will go
off even with the fault disarmed. This fault is included in the summary alarm and contacts on the
SCR Driver board if it is armed.
GFI Armed or Disarmed
“GFI” stands for Ground Fault Indicator. This fault occurs when the charger detects a leakage
current from the battery negative or positive to the charger ground of more than the threshold
value. The threshold value is factory set with a 10K-ohm resistor. This menu allows the user to
arm or disarm the “GFI” fault codes and the optional ALARM I/O Relay board contacts. The two
faults that are displayed are the “GFI –“ and “GFI +”. The GFI set points are also set in the Alarm
Settings menu.
EOD Armed or Disarmed
“EOD” stands for End of Discharge voltage. This fault occurs when the charger detects a DC
voltage lower than the value in the “EOD set point” menu. This menu allows the user to arm or
disarm the “EOD” fault code and optional ALARM I/O Relay board contacts.
DC Hi 2.50V/C
This is the “DC Hi” set point menu. The user can set the value that the charger will give the “Hi
DC” fault. This is factory set at voltage per cell but can be changed to voltage (of the entire
battery set). (Factory set @ 2.50V/C with a range of 1.00 to 2.70V/C)
HiLoc 2.50V/C
This is the “HiLoc” set point menu. The user can set the value that activates the “HiLoc” fault.
This is factory set at voltage per cell but can be changed to voltage (of the entire battery set).
(Factory set @ 2.50V/C with an adjustable range of 1.00 to 2.70V/C)
DC Lo 2.10V/C
This is the “DC Lo” set point menu. The user can set the value that the charger will give the “Lo
DC” fault. This is factory set at voltage per cell but can be changed to voltage (of the entire
battery set). (Factory set @ 2.10V/C with a range of 1.00 to 2.50V/C)
EOD 1.70V/C
