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 Delta-Q 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.
Battery posts and terminals must be clean and free of corrosion.
Check that electrolyte level just covers plates.
Plug in charger for at least a 16 hour charge.
Check and fill electrolyte.
Drive the vehicle for less than half the distance normally driven.
Repeat the above steps until the Delta-Q goes green 100% charge on a 16 hour charge.
If repeated 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 Section 4.6.
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
= Delta-Q 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 Delta-Q and requires Charger replacement
and return.
4.5.3 CHECK / CHANGE CHARGING ALGORITHM
The Delta-Q Charger has been programmed for use with the Columbia ParCar supplied batteries and contains ten
algorithms for use with different batteries. The Table 2 details these battery models.
NOTICE: For maximum battery life the correct algorithm must be used.
NOTICE: If your battery model is not listed in Table A, contact Delta-Q for further information.

Each time AC power is applied with the battery pack NOT connected, the charger enters an algorithm select/display
mode for approximately 11 seconds.
During this time, the current algorithm # is indicated on the 80% LED light. A single digit algorithm # is indicated by
the number of blinks separated by a pause. A two digit algorithm # is indicated by the number of blinks for the first
digit followed by a short pause, then the number of blinks for the second digit followed by a longer pause.
