1.
If the GREEN and RED lights do not illuminate
within three (3) seconds after the AC power is
applied to the charger, it indicates one of the
following:
a.
Charger "POWER" switch is not in "ON"
position.
b.
Charger is not plugged into a live AC outlet.
2.
If both lights go off and stay off three to five (3-5)
seconds after the charger connections are
completed, it indicates one of the following and
the charger is prevented from turning on:
a.
DC plug not connected to the wheelchair
receptacle.
b.
Fault in wheelchair wiring. Poor or open
connections in the wheelchair wiring that
connects to the batteries; corroded
terminals, loose or worn plugs and
receptacles, loose or worn fuseholders.
(Have your dealer repair the wheelchair.)
c.
Battery connections in wheelchair wrong
(reverse polarity).
d.
One or both batteries no longer serviceable
(voltage below 7 volts for a 24-volt system).
3.
If the charger turns off before the batteries are
fully charged, it indicates one of the following:
a.
Charger internal thermal breaker turned the
charger off due to overheating because
charger ventilation openings are blocked.
After the charger has cooled down to a safe
temperature, it will automatically restart. If
the charger repeatedly overheats, it may be
malfunctioning.
b.
The AC power was interrupted during
charge.
c.
The DC cord charging plug accidentally
disconnected during charge.
d.
Fault in wheelchair wiring. The wheelchair
charging circuit has high resistance,
corroded or loose connections; loose or
worn wheelchair charging receptacle, loose
or worn wheelchair fuseholders.
4.
A decrease in wheelchair range where the chair
loses power earlier and earlier in the day
indicates one of the following:
a.
Using the wheelchair before batteries are
fully charged and charger is turned off
shortens battery life and begins reducing
daily range. This battery capacity loss is
permanent and not recovered with additional
charge cycles.
b.
Conventional replaceable liquid electrolyte
batteries are being under charged on the gel
cell "BATTERY TYPE" switch setting.
Battery capacity lost in this manner is
permanent and is not recovered with
additional charge cycles.
c.
Severe overcharging occurs when gel cell
(maintenance-free) batteries are charged on
the conventional wet led acid "BATTERY
TYPE" switch setting. Battery capacity lost
in this manner is permanent and occurs very
rapidly. Check with your dealer about
battery replacement.
d.
The battery has been allowed to sulfate.
Charge the battery no less frequently than
once every three (3) days when the
wheelchair is lightly utilized. Once sulfation
is allowed to take place, it may be partially
reduced by returning, temporarily, to daily
charging.
e.
The electrolyte level in conventional liquid
electrolyte lead-acid batteries was allowed
to drop below the top of the battery plates.
Add distilled water to just cover the tops of
the plates immediately upon discovery and
fill to the proper level with distilled water at
the completion of the very next charge cycle.
Battery capacity lost in this manner is
permanent and is not recovered with
additional charge cycles.
f.
This is the normal wearout process for all
types of deep-cycle motive power batteries.
5.
If battery voltage does not exceed 18 volts after
10 minutes of charging, the charger turns off and
the RED light will turn on steady indicating one
of the following:
a.
Improper batteries used with charger. Must
be a 12-cell, series connected 2.38-2.50
volts per cell battery system.
b.
Failed cells in the battery do not allow the
battery voltage to rise above 18 volts.
6.
The charger operates through 16 hours before
turning off. The RED light will begin to blink very
rapidly indicating one of the following:
a.
Batteries of higher than 90 amp-hour
capacity (20 hr. rate) can require more than
16 hours to charge.
b.
New batteries (5 cycles or less) can require
more than 16 hours to charge.
