CIRCUIT BOARD
REMOVAL/REPLACEMENT
No special tools (other than a grounding wrist strap
and InPower Service tool with PCC1301 Interface Kit)
are required to remove a circuit board from in-side the
control box. The InPower Service tool is required when
replacing the Base board. Before replacing the Base
board, make sure that a capture file of the genset’s
parameter values has been created using InPower.
(During genset installation, it was suggested that a
capture file be made before and after changes were
made to the genset operating parameters.)After
replacing the Base board, use the capture file as a
template to write the previous settings to the new Base
board software. Refer to INPOWER User’s Guide for
specifics.
Circuit Board Removal Safety Precautions Turn off
or remove AC power from the battery charger and then
remove the negative (–) battery cable from the set
starting battery. This is to make sure that the set will
not start while working on it and to avoid circuit board
damage, caused by voltage spikes when removing
and replacing circuit board connectors. To prevent
circuit board damage due to electrostatic discharge
(ESD), a grounding wrist strap must be worn when
handling circuit boards or socket-mounted IC’s. (The
wrist strap does not provide a direct short to ground,
but is typically rated at approximately 1 mega ohm to
ground.)Attach the clip to the chassis ground screw in
the control box and place the strap around your wrist
before handling a circuit board.
WARNING
Ignition of explosive battery
gases can cause severe personal injury or death.
Arcing at battery terminals, light switch or other
equipment, flame, pilot lights and sparks can
ignite battery gas. Do not smoke, or switch trouble
light ON or OFF near battery. Discharge static
electricity from body before touching batteries by
first touching a grounded metal surface. Ventilate
battery area before working on or near battery—
Wear goggles—Stop genset and disconnect
charger before disconnecting battery cables—
Disconnect negative (–) cable first and reconnect
last.
CAUTION
Disconnect battery charger
from AC source before disconnecting battery
cables. Otherwise, disconnecting cables can result
in voltage spikes damaging to DC control circuits
of the genset.
WARNING
Accidental starting of the
generator set can cause severe personal injury or
death.
Prevent
accidental
starting
by
disconnecting the negative (–) cable from the
battery terminal.
CAUTION
Electrostatic
discharge
will
damage circuit boards. Always wear a grounding
wrist strap when handling circuit boards or socketmounted IC’s
