NOTICE:
If the batteries are excessively discharged, the charger will not be able to charge the complete
set of batteries. The remote LED will be flashing red.(see Red Light Charger Error Codes). It will then be
necessary to follow the Special Charging for Excessively Discharged Batteries.
When the charger has completed approximately 80% state of charge the remote LED will flash long green as the last
20% of charge is returned to the batteries in the second phase (constant voltage phase).
NOTICE:
You can terminate charging at this point if necessary. The vehicle can be used, but completing
the charge cycle is highly recommended.
A Green LED continuously lit indicates the batteries are completely charged. The charger may now be unplugged
from the AC source. If the batteries will not be used for a length of time, check monthly for the charge level. It is also
acceptable to leave the charger plugged in. The charger has the capability to test and recharge if necessary.
Repeated “Short Charging”, leaving the charge short of 100% will shorten operating cycle distance and reduce
battery life.
A fault occurring while charging causes the remote LED to flash with a code relaying the error. Some errors may
require repair by a qualified technician and others may be simply transient and will automatically recover when the
fault condition is eliminated and the charger cycled by disconnecting the AC source for a minimum of 11 seconds.
NOTICE:
A Yellow (Amber) flashing remote LED indicates the thermostatic control has limited the charger
output due to ambient temperature conditions. It is still charging, but at a reduced rate.
RED LIGHT CHARGER ERROR CODES DELTA Q Model
1 FLASH
= Battery Voltage High: Auto-recover. May be temporary condition, or wrong charger installed, i.e. 36 volt
charger on 48 volt battery pack.
2 FLASH
= Battery Voltage Low: Auto-recover. Confirm each individual batteries minimum voltage with a voltmeter.
Two or more 6 volt batteries register less than 5.85 volts, or accumulative total pack voltage has been discharged to
less than 20% remaining. Vehicle operation will cease until batteries are recharged. See
SECTION 4 ELECTRIC
SYSTEM,
EXCESSIVELY DISCHARGED BATTERIES.
3 FLASH
= Charge Timeout: The charging did not complete in allowed time, 12-14 hours. This may indicate a battery
problem, or that the charger output was reduced due to high ambient temperatures. Disconnect AC supply, confirm
sufficient ventilation, allow cool down time, and restart charger.
NOTICE:
If the charger is exhibiting a 3 flash fault and it has been determined that the cause was not due
to ventilation or high ambient temperature, the following procedure may restore the battery pack to normal
operation.
1. Battery posts and terminals must be clean and free of corrosion.
2. For non-sealed batteries, check that electrolyte level just covers plates.
3. Plug in charger for at least a 16 hour charge.
4. Drive the vehicle for less than half the distance normally driven.
5. Repeat the above steps until the charger goes green 100% charge on a 16 hour charge.
If repeated charge cycles (5-7) do not result in a 100% green charge, the batteries are beyond useful life
and will need replacement.
4 FLASH
= Check Battery: The batteries could not be trickle charged up to a minimum level to start charger. This
may be the result of badly discharged batteries, or one (or more) damaged cells. See EXCESSIVELY DISCHARGED
BATTERIES.
5 FLASH
= Over-Temperature: The charger shutdown due to high internal temperature. May require reset (AC
unplugged) and cool down to restart charging cycle. This fault may indicate inadequate cooling airflow or high
ambient air temperatures. Check for debris or blockage at cooling fins. Move the vehicle to a cooler, well ventilated
area, or adjust time of day when charging.
6 FLASH
= Charger Fault: A fault was detected either in the batteries or in the charger. The batteries must be tested
to ensure there is no damage to one or more cells. If the batteries are found to be good, the charger may need to be
replaced by a qualified technician.
A STEADY RED FAULT LED
confirms an internal electrical fault of the charger and requires charger replacement
and return.
