2.2.7.4 CHARGE INDICATIONS
The following indications are not necessarily a result of a charger problem. They are typically caused by external problems such
as AC line, poor battery conditions, connections, etc. If abnormal charge conditions are detected, the charge is terminated, the red
FAULT indicator lights and the display shows the code:
DISPLAY DESCRIPTION POSSIBLE CAUSE
F0
SHORTED
CELL
#.##VC
##:##HM
Battery voltage did not reach 2.00 V/C within 30 minutes.
#.##VC is the volts per cell at end of charge and ##:##HM
is the charge time. - Shorted Cell
- Open diode
- Low Charging amps
- Low AC line voltage
- Wrong size battery
- Battery over-discharged
F1
SHORTED
CELL
#.##VC
##:##HM
Battery did not reach gassing voltage within the allowable
time. #.##VC is the volts per cell at end of charge and
##:##HM is the charge time. - Shorted Cell
- Open diode
- Low Charging amps
- Low AC line voltage
- Wrong size battery
- Battery over-discharged
F2 HOT
BATTERY
###°F #.##VC
Hot battery. The battery exceeded the NT temperature.
###°F is the battery temperature and #.##VC is the volts
per cell at end of charge. - Battery is overheated
- Damaged thermal sensor
- Faulty control board
F3 LOW
VOLTS
###A #.##VC
Low battery voltage, less than 1.60 V/C at start up. ###A
is the charger current and #.##VC is the battery volts per
cell. - Wrong size battery
- Battery over-discharged
- Voltage jumper setting incorrect
F4 HIGH
VOLTS
###A #.##VC
High battery voltage, more than 2.40 V/C at start up.
###A is the charger current and #.##VC is the battery
volts per cell. - Wrong size battery
- Battery fully charged
- Voltage jumper setting incorrect
F5 NO DC
CURRENT
###A #.##VC
No charging current to the battery. ###A is the current at
the end of charge and #.##VC is the volts per cell at end
of charge. - Faulty AC line contactor
- Open diode
- Faulty resonant capacitor
- Poor battery connections
- Open cell
- Faulty control board
F6 CHARGE
ERROR
###A #.##VC
Charger current or voltage not what was requested by
control. ###A is the current at the end of charge and
#.##VC is the volts per cell at end of charge. - Incorrect control setup
- Poor battery connections or open Cell
- Faulty HF module
- Faulty adapter board or cable
- Faulty control board
F7 LONG
CHARGE
#.##VC
##:##HM
Long charge, the charger ran longer than the allowed time.
#.##VC is the volts per cell at end of charge and ##:##HM
is the charge time. - Open diode
- Low Charging amps
- Low AC line voltage
- Wrong size battery
- Battery over-discharged
F8
CHARGER
ON
###A #.##VC
Charger stayed on when control requested it to shut off.
###A is the charger current and #.##VC is the battery
volts per cell. - AC line contactor stuck on
- Open shunt sense lead or loose connection
- Incorrect control setup
- Missing or damaged current sensor
- Faulty control board
F9 BAD
KEYPAD
###A #.##VC
Faulty keypad detected. One or more buttons are stuck on.
###A is the charger current and #.##VC is the battery
volts per cell. - Faulty keypad
- Faulty control board
F10 HIGH
CURRENT
###A #.##VC
Charging current exceeds 110% of shunt setting. ###A is
the current at the end of charge and #.##VC is the volts
per cell at end of charge. - High charging amps or high AC line voltage
- Missing or damaged current sensor
- Incorrect shunt size
- Open shunt sense lead or loose connection
- Faulty control board
F11
TEMP
ERROR
255°F #.##VC
No thermal sensor. #.##VC is the battery volts per cell. - Missing or damaged thermal sensor
- Thermal sensor enabled when not installed
- Faulty control board
