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 keypad will be solid RED and the display shows the code:
DISPLAY
DESCRIPTION
POSSIBLE CAUSE
F0 SHORTED CELL
##:##
Battery voltage did not reach 2.00 V/C within
30 minutes. ##:## is the charge time.
- Shorted Cell
- Open diode
- Low Charging amps
- Low AC line voltage
- Wrong size battery
- Battery over-discharged
F1 SHORTED CELL
##:##
Battery did not reach gassing voltage within
the allowable time. ##:## 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
Hot battery. The battery exceeded the NT
temperature. ###°F is the battery temperature
- Battery is overheated
- Damaged thermal sensor
- Faulty control board
F3 LOW VOLTS
#.## V/C
Low battery voltage, less than 1.60 V/C at start
up. #.## V/C is the battery volts per cell.
- Wrong size battery
- Battery over-discharged
- Voltage jumper setting incorrect
F4 HIGH VOLTS
#.## V/C
High battery voltage, more than 2.40 V/C at
start up. #.##V/C is the battery volts per cell.
- Wrong size battery
- Battery fully charged
- Voltage jumper setting incorrect
F5 NO DC CURRENT
### AMPS
No charging current to the battery. ### AMPS
is the current at the end of charge.
- Faulty AC line contactor
- Open diode
- Faulty resonant capacitor
- Poor battery connections
- Open cell
- Faulty control board
F6 CHARGE ERROR
### AMPS
Charger current or voltage not what was
requested by control. ### AMPS is the current
at the end of charge.
- Incorrect control setup
- Poor battery connections or open Cell
- Faulty HF module (HF chargers)
- Faulty firing board or cable (CF chargers)
- Faulty control board
F7 LONG CHARGE
##:##
Long charge, the charger ran longer than the
allowed time. ##:## is the charge time.
- Open diode
- Low Charging amps
- Low AC line voltage
- Wrong size battery
- Battery over-discharged
F8 CHARGER ON
### AMPS
Charger stayed on when control requested it to
shut off. ### AMPS is the charger current.
- AC line contactor stuck on
- Open shunt sense lead or loose connection
- Incorrect control setup
- Faulty control board
F9 BAD KEYPAD
Faulty keypad detected. One or more buttons
are stuck on.
- Faulty keypad
- Faulty control board
F10 HIGH CURRENT
### AMPS
Charging current exceeds 110% of shunt
setting. ### A<PS is the current at the end of
charge.
- High charging amps or high AC line voltage
- Incorrect shunt size
- Open shunt sense lead or loose connection
- Faulty control board
F11
TEMP
ERROR
255°F
No thermal sensor.
- Missing or damaged thermal sensor on Tobi
- Thermal sensor enabled when not installed
- Faulty Tobi
- Faulty control board
