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
T
he 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 A details these battery models.
TABLE A
ALGORITHM #
BATTERY TYPE
126
Full River or Equivalent 85ah-145Ah AGM (DC115-12)
125
Full River or Equivalent 160ah-220ah AGM (DC180-6/DC224-6)
72
US Battery or Equivalent 250ah-335Ah Flooded Constant Power dv/dt (USB 305HC)
43
Discover or Equivalent 200ah-400ah AGM (EVL16A/EVGC6A/EV185A)
42
Discover or Equivalent 80ah-150ah AGM (EV31A)
11
US Battery or Equivalent 200ah-255ah flooded Constant Power dv/dt (USB2200/USB145)
5
Trojan or Equivalent 85ah-150ah Group 31 12v Flooded
1
Trojan or Equivalent 150ah-260ah 6v/8v/12v Flooded (T105)
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. It will also be displayed on the remote LED.
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.
