Battery Charging Status Indicators
The battery charging status indicators are located just above
the Charger AC input receptacle on the center cover section at
the rear of the machine. This LED indicator set is plugged
directly into a connector on the back of the battery charger
and indicates current charging status.
When first plugged in, the charger will automatically turn on
and go through a short LED indicator self-test (all LED’s will
flash in an up-down sequence for two seconds), then charging
will begin.
1.
The YELLOW ‘CHARGING’ LED will turn on and a trickle
current will be applied until a minimum voltage is
reached.
Once a minimum battery voltage of 2 volts per cell is
detected, the charger will enter the bulk charging con
-
stant-current stage and the YELLOW ‘CHARGING’ LED
will remain on. The length of charge time will vary by
how large and how depleted the battery pack is, the
input voltage (the higher, the better), and ambient tem
-
peratures (the lower, the better). If the input AC voltage
is low (below 104VAC), then the charging power will be
reduced to avoid high input currents. If the ambient
temperature is too high, then the charging power will
also be reduced to maintain a maximum internal tem
-
perature.
2.
When the GREEN ‘CHARGED’ LED turns on, the batteries
are completely charged.
The charger may now be unplugged from AC power
(always pull on plug and not cord to reduce risk of dam
-
age to the cord). If left plugged in, the charger will auto
-
matically restart a complete charge cycle if the battery
pack voltage drops below a minimum voltage or 30 days
has elapsed.
3.
If a fault occurred anytime during charging, a fault indi
-
cation is given by flashing the RED ‘FAULT’ LED with a
code corresponding to the error.
There are several possible conditions that generate
errors. Some errors are serious and require human inter
-
vention to first resolve the problem and then to reset
the charger by interrupting AC power for at least 10 sec
-
onds. Others may be simply transient and will automati
-
cally recover when the fault condition is eliminated. To
indicate which error occurred, the RED ‘FAULT’ LED will
flash a number of times, pause, and then repeat.
[1 FLASH]
Battery Voltage High: auto-recover. Indicates
a high battery pack voltage.
[2 FLASH]
Battery Voltage Low: auto-recover. Indicates
either a battery pack failure, battery pack is not con
-
nected to charger, or battery volts per cell is less than 0.5
VDC. Check the battery pack and battery pack connec
-
tions.
[3 FLASH]
Charge Time-out: Indicates the battery did
not charge within the allowed time. This could occur if
the battery is of a larger capacity than the algorithm is
intended for. It can also occur if the battery pack is dam
-
aged, old, or in poor condition. In unusual cases it could
mean charger output is reduced due to high ambient
temperature.
[4 FLASH
] Check Battery: Indicates the battery pack
could not be trickle charged up to the minimum 2 volts
per cell level required for the charge to be started. This
may also indicate that one or more cells in the battery
pack are shorted or damaged.
[5 FLASH]
Over-Temperature: auto-recover. Indicates
charger has shutdown due to high internal temperature
which typically indicates there is not sufficient airflow
for cooling – see step 1 of Installation Instructions. Char
-
ger will restart and charge to completion if temperature
is within accepted limits.
[6 FLASH]
Qui-Q Fault: Indicates that the batteries will
not accept charge current, or an internal fault has been
detected in the charger. This fault will nearly always be
set within the first 30 seconds of operation. Once it has
been determined that the batteries and connections are
not faulty and Fault 6 is again displayed after interrupt
-
ing AC power for at least 10 seconds, the charger must
be brought to a qualified service depot.
