Troubleshooting; General - Yale 524150797 Maintenance Manual

2200 YRM 1508
During this step, the yellow, CHARGING, LED
will flash on and off every two seconds. The
charger is checking for faults prior to the start of
charging. Depending on the condition and state
of charge of the batteries, this step can take
from 5 seconds up to 5 hours. This stage lasts
15 seconds unless battery voltage is below 21V.
If the battery voltage is below 21V, the charger
will charge the battery with low current until
battery voltage reaches 21V. When battery
voltage is above 21V, regular charging begins.
Constant Current
2
This step is sometimes referred to as Bulk
Charge. During this step, the charger will charge
at constant current mode, which is normally the
charger's full rated RMS output. The yellow,
CHARGING, LED will be constantly illuminated
during this step.
Constant Voltage
3
This step is
Absorption Charge or Top Off stage. During this
step, the charger will regulate the voltage at a
constant rate while slowly decreasing the bulk
charge current. The yellow, CHARGING, LED
will remain illuminated. When the batteries have
reached 80 to 90 percent of full charge, the
yellow, CHARGING, and the green, CHARGED,
LEDs will be illuminated.
Charge Complete
4
During this step, only the green, CHARGED,
LED will remain illuminated. AC power can now
be disconnected from the charger.
Recycle Stage.
5
If the charger remains connected to power for a
period of days (40 days when Mode 2 is
selected), a completely new charge cycle will
begin to keep batteries fully charged during long
periods of not being used.
Equalization Stage
6
Equalization stage will happen only when Mode
2 is selected. During this stage, the Power LED
flashes.
Equalization mode takes 2-4 hours longer than
the regular cycle.
The charger will go through an equalization
cycle every 15 charge cycles or if the battery
has been without charging for more than 30
days. If an equalization cycle is not desired,
disconnect and reconnect AC power to reset the
charge counter to 1 and skip the Equalization
Stage.
NOTE: If the charger noted an abnormal charge
condition during the charging, the charger will attempt
sometimes referred
to shutdown and will flash one or all three of the red
LEDs on the top of the charger. If this condition occurs,
see Troubleshooting in this section.
Operating temperature range for the charger is
-10 to 50°C (14 to 122°F). If charger is below or above
indicated temperatures, locate the truck to an area
where charger can return to the operating temperature
range.

TROUBLESHOOTING

General

NOTE: The charger runs a pre-qualifying test (yellow
charging light flashing) at the beginning of the charge
cycle to determine the condition of the battery. This
test may last from 45 minutes to five hours. After the
test is complete, the charger should begin charging
(yellow charging light continuous) or may display an
Error Mode by flashing one or more of the red LEDs. If
to as
an Error Mode is displayed, stop the general
troubleshooting and follow the chart and procedures in
Error Modes in this section.
1. Check AC power supply to charger:
a. Connect the charger plug to a 120 volt AC
power source using a 20 amp rated extension
cord.
b. Do all 5 LEDs simultaneously flash at least
once upon connection? (LEDs should flash
between one to four times depending on
battery type/mode configuration.)
(1) YES: Proceed to Step 2.
(2) NO: Check AC power supply to charger:
Inspect all cabling for proper connections
(check for loose or corroded connectors) or
broken wires. Repair as necessary and
repeat Step 1. If LEDs still do not flash at
least once upon connecting power, replace
the charger.
2. Check that the charger is configured for the
proper battery mode/type:
a. What is the proper charger mode for the type
batteries being used?
(1) Refer to Charger Mode/Battery Type
Selection.
b. What mode is the charger currently set on?
