BATTERY CHARGER ______________________________________________________
The battery charger is designed to fully charge the
battery pack and will shut off automatically when the
batteries are fully charged. Read the instruction manual
included with the charger for proper operating procedure.
An AC power extension cord, not included with mower, is
required to use the battery charger. The cord should be
as short as possible (must be less than 100 feet long)
and a minimum of 12 AWG.
Always connect the charger to a dedicated, grounded
outlet protected by a 15 or 20 amp circuit breaker.
Before charging, the following should be observed:
The charging must take place in an area that is well
ventilated and capable of removing the hydrogen gas
that is generated by the charging process. A minimum of
five air exchanges per hour is recommended.
The charger AC cord is fully inserted into the charger
receptacle.
The charger AC cord is protected from damage and is
located in an area to prevent injury that may result from
personnel running over or tripping over the cord set.
If the charger is not operating correctly, unplug charger
from both the AC outlet and the mower and check the
fuse.
Battery Power Modules:
The battery charger is installed under the hood of the
vehicle, and is always connected to the battery pack.
If this is the first time charging the batteries, or if charger
was removed from this mower to charge buffer batteries
on a hybrid mower, check charger algorithm before
charging. Algorithm 38 (Preferred) or 11 (Alternate)
should be used. See Section 7.9.
1.
Make certain ignition switch is off. Disconnect battery
pack power connector.
2.
Lift up on the charger receptacle cover on the left
side of the machine. Plug end of the AC extension
cord into charger receptacle.
3.
Plug the AC power cord from the charger into a
suitable wall outlet.
4.
Charging time should be between 4-6 hours.
5.
When the batteries are fully charged, the charger
will turn off automatically. Unplug the charger AC
cord from the wall outlet first, then disconnect the
cord from the mower. Store the AC cord in a safe
location for the next time charging is required.
Buffer Batteries on Hybrid Power Modules:
The buffer batteries were designed to be charged by the
generator, however they can be recharged using an
external charger if needed. An external charger is not
included with the mower and must be purchased
separately. Order charger part number 4203742 (Delta-
Q). Batteries can also be removed from mower and
changed individually using a 12 volt charger.
The 4203742 Delta-Q charger comes with the default
algorithm programming set for charging the battery
power module batteries and must be switched to a
different algorithm for charging the buffer batteries. Set
charger to use algorithm 66. See Section 7.9.
1.
Make certain ignition switch is off. Disconnect buffer
battery pack connector.
2.
Delta Q Charger: Using insulated tools, connect
charger leads to buffer battery pack, using same
terminals buffer battery connector is attached to.
Eclipse Walker Charger: Connect harness adapter
4229560 (Order Separately) to both charger
connector and buffer battery connector.
3.
Plug end of the AC extension cord into charger
receptacle.
4.
Plug the AC power cord from the charger into a
suitable wall outlet.
5.
When the batteries are fully charged, the charger
will turn off automatically. Unplug the charger AC
cord from the wall outlet first, then disconnect the
cord from the mower. Store the AC cord in a safe
location for the next time charging is required.
6.
Disconnect charger from buffer battery pack.
WARNING
Hydrogen is explosive in concentrations as low as 4%
and is generated in the charging cycle of electric
mowers. Because it is lighter than air, it will collect in
the ceiling of buildings necessitating proper
ventilation. Air exchanges of 5 changes per hour is
considered the minimum requirement.
Never smoke around batteries.
Never charge batteries in an area that has open flame
or electrical equipment that could cause an electrical
arc.
Be sure that the key switch is off, all electrical
accessories are turned off, and power connector is
disconnected before starting work on vehicle.
Remove all jewelry (watches, rings, etc.).
