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 4.8).
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.
4.7.4 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 A details these battery models.
TABLE A
ALGO126RITHM BATTERY TYPE
126 Full River 100Ah AGM
125 Full River 200Ah AGM
72 Generic 250-335 Ah Flooded Constant power dv/dt
43 Discovery AGM
42 Discover AGM 80 – 150 Ah
11 Generic 200-255 Ah Flooded Constant power dv/dt
5 Trojan 30XHS
4 US 2200, US 145 (Standard)
1 Trojan Flooded
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 (No. 4, Fig 4.7.1). 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.
To check/change the charging algorithm:
Disconnect the charger positive connector from battery pack. Apply AC power and after the LED test, the
algorithm # will be displayed for 11 seconds.
