6. Equalization Stage
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 cy-
cle 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 con-
dition during the charging, the charger will attempt to
shutdown and will flash one or all three of the red
LEDs on the top of the charger. If this condition oc-
curs, see Troubleshooting (Accusense 20A Charg-
ers), Error Modes in this section.
Operating temperature range for the charger is -10 to
50°C (14 to 122°F). If charger is below or above indi-
cated temperatures, locate the truck to an area where
charger can return to the operating temperature
range.
CHARGER MODE/BATTERY TYPE
SELECTION (ACCUSENSE 20A)
WARNING
DO NOT use batteries types that are not approved
for the charger or improper mode settings. Dam-
age to the batteries or charger may occur if the
mode setting is not correct for the type of batter-
ies being used. If the battery manufacturer of the
battery you are using is not listed, contact Service
Engineering through the Contact Management
System.
NOTE: Mode settings can be checked by connecting
the battery charger to a 120V AC power source and
watching the LED display. The LED display will flash
once if the mode is set to Mode 1, twice if set to Mode
2, three times if set to Mode 3, and so forth. If the
LEDs do not flash when initially connected to power,
refer to Troubleshooting (Accusense 20A Chargers) in
this section.
NOTE: If the battery manufacturer of the battery you
are using is not listed, contact Service Engineering
through the Contact Management System.
The battery charger has 6 mode settings. The proper
mode setting is determined by the type batteries be-
ing used in the battery pack. See Table 8.
After you determine the proper mode for the replace-
ment batteries (for lift trucks manufactured before
May, 2013), set the charger to the proper mode by in-
stalling the corresponding mode key for that mode
into the mode port. Refer to Figure 33 for key position
and the
Parts Manual for mode key part numbers.
