HEAT VENTILATION
Holes are designed in the case to allow hot air to escape to help keep the electronic circuitry cool. This helps to maintain
accurate operation and maximize the lifespan of the charger itself. CAUTION: Do not block the vent holes during
operation, as it could cause the charger to overheat and possibly cause permanent damage.
ERROR INDICATIONS AND SAFETY FEATURES
Solid-state circuitry protects the charger against potential damage which could be caused by short-circuit or reverse
polarity conditions. If power is connected backwards to TritonEQ’s input, the screen may turn black and no other operation
will occur, but it will be protected from damage. Re-check all input connections to make sure it is connected properly.
The following error messages will show on-screen to protect the charger and battery from damage due to improper
connection, input voltage, etc. These messages will be accompanied by loud tones on the buzzer. When any message
appears, refer to the corresponding problem and solution explanation. Press ENTER to clear the warning.
Error Displayed Problem and Solution
Input voltage When input voltage is under 11.0V or over 15V.
No battery When a battery is not detected at the charger’s output.
Open circuit When a battery becomes disconnected while a function is in progress.
Reverse polarity When a battery is connected to the output in reverse.
Overheating The temperature inside the charger’s case is too high. TritonEQ will pause the current function
and show this message. The function will resume automatically after the charger has cooled to
an acceptable level.
Time limit over When the charge safety timer has expired (1.5 hours for NiCd/MH, and 3 hours for LiPo/Ion
batteries.
Internal error When a problem exists within the control circuitry of the charger.
Batt volts too high When the voltage setting in the charger is too low. It may take up to 5 minutes for this error to show.
Batt volts too low When the voltage setting in the charger is too high. It may take up to 5 minutes for this error to show.
TROUBLESHOOTING GUIDE
PROBLEM: Display does not work when unit. Check power supply for proper power. Check input connections for
proper contact.
PROBLEM: Charger doesn’t recognize battery. Make sure battery is not connected backwards. Check for faulty
connection or wiring. Perhaps there is a defective cell in the pack, in which case the pack should be replaced.
PROBLEM: Does not automatically stop charge after 1.5 hours for NiCd/MH batteries, or 3 hours for LiPo/Ion batteries.
Internal problem might exist. Disconnect battery IMMEDIATELY and contact Hobby Services.
PROBLEM: Battery voltage low after charge is completed. Make sure charge current setting isn’t too low. Battery might
be defective and require replacement. Check to see if the backup safety timer expired before full charge was reached.
For lithium batteries, make sure the battery capacity value entered in the programming matches the rated capacity of
the battery.
PROBLEM: Will not lock into discharge mode. An improper discharge voltage was entered for the battery. Adjust the
battery voltage in the discharge screen to match the number of cells in the pack. Tx might have a diode in charge circuit,
in which case it’s best to connect the battery to the charger directly (outside of the Tx). Battery might be defective and
require replacement. Battery might already be discharged.
PROBLEM: Low mAh readings after discharge. Batteries might not have been fully charged prior to discharge. Batteries
might have been old or unused for an extended period of time, which may require additional cycles to see if capacity
improves. Battery might be defective and require replacement. Discharge current setting might be too high, and should
be lowered. An improper discharge voltage was entered for the battery. Adjust the battery voltage to the proper value for
the battery. Battery might already be discharged.
PROBLEM: LCD and/ or controls do not function properly. Input power might be connected backwards, and require re-
connection. Input fuse might be blown and require replacement.
