NOTICE: Do not cover the charger cabinet or cooling fins with clothing, blankets, or other material. Fins
provide ventilation and prevent overheating.
Do not disassemble the charger. There are no serviceable components.
4.5.1 CHARGER OPERATING INSTRUCTIONS
Connect the supplied power cord to the vehicle charger receptacle and to a properly grounded wall outlet. Charger
start and charge time is automatic. The Yellow AC power LED (Fig. 4.5.1 No. 1) should remain illuminated while the
Charger is plugged into an AC source. The remote LED will be flashing short green. If these LED’s are not lit, before
replacing Charger, recheck the AC connection and the AC source fuse or breaker. If this fails to correct the problem,
contact your Columbia Dealer for assistance.
Charger will automatically turn on and conduct a short self-test and battery test.
All Delta Q LED’s will flash in sequence and then a trickle current will be applied to batteries until a minimum voltage
is reached. In Figure 4.5.1 No. 3 indicates the Bar Graph and No. 2 indicates the lowest LED. Three (3) amperes is
displayed as the lowest LED on the Bar Graph.
If the batteries meet the minimum voltage requirements of the Charger, signifying they are serviceable (chargeable),
the Charger enters the bulk charging (higher amperage-constant current) stage. The Bar Graph LED’s indicate the
electrical current being delivered to the batteries as the Charger moves through its automatic charge profile.
The length of charge time at each level will vary due to battery size and battery charge depletion. The remote LED
will be flashing short green.
NOTICE: If the batteries are excessively discharged, the Delta-Q Charger will not be able to charge the
complete set of batteries. The Delta-Q RED FAULT LED (Fig. 4.5.1 No. 6) and the remote LED will be
flashing red. (See Section 4.5.2 Red Light Charger Error Codes). It will then be necessary to follow the
Special Charging for Excessively Discharged Batteries, Section 4.6.
When the Yellow 80% LED (Fig 4.5.1 No. 4) is lit, the Charger has completed the bulk stage and the batteries are at
approximately 80% state of charge. The 80% LED remains on as the last 20% of charge is returned to the batteries in
the second phase (constant voltage phase). At this time the remote LED will flash long green.
NOTICE: You can terminate charging at this point if necessary. The vehicle can be used, but completing
the charge cycle is highly recommended.
Repeated “Short Charging” leaving the charge short of 100% will shorten operating cycle distance and reduced
battery life.
A low current “finish-charge” phase returns and maintains batteries to maximum capacity. The 100% Green LED’s will
blink until “finish charge” phase is complete.
A 100% 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 Delta-Q has the capability to test and recharge if necessary.
A fault occurring while charging causes the RED FAULT LED and 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 Delta-Q cycled by disconnecting the AC source
for a minimum of 11 seconds.
NOTICE: A Yellow (Amber) flashing LED in the upper Bar Graph (Fig. 4.5.1 No. 3) and a flashing yellow
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.
4.5.2 RED LIGHT CHARGER ERROR CODES
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 EXCESSIVELY
DISCHARGED BATTERIES Section 4.6.
