Pump Driver (EPD) Module
The Electric Pump Driver (EPD) replaces the servo valve.
System flow is controlled by regulating the pump speed.
MODULE INSTALLATION NOTE:
The mounting surface
must be cleaned so it is free from dirt, moisture and oil
residues. Failure to clean the mounting surface may result in
the EPD working loose.
Remove the GREEN backing from the Dual-Lock
™
fasteners
on the bottom of the EPD unit. Position the EPD where
wiring will work the best. (A clean surface is desirable.)
Extension cables are available. Firmly press the EPD into
place. Secure the EPD to the equipment using plastic cable
ties to prevent the EPD from coming into contact with
moving parts if the Dual-Lock
™
fasteners should work loose.
If desired, the EPD can be fastened with screws, using the
holes in the mounting flanges.
ELECTRICAL INSTALLATION
This section explains how to connect your EPD to a 12-volt
power source, and how to connect your EPD to your
MT-3405D harness.
Note: The EPD must be connected to a 12-volt DC negative
ground electrical system.
BATTERY POWER CONNECTION
Locate the power cable, P/N 14499 and route to the battery.
In routing cable avoid areas where the cable may be
subject to abrasion or excessive heat. Attach the BLACK
wire (ground) to a screw or bolt on the equipment frame.
See Illustration to the upper right. Be sure there is a good
metal-to-metal contact. Connect the ORANGE wire to the
positive battery terminal.
Connect the power to the EPD by plugging the 3-pin W/P
tower on the power cable into the 3-pin W/P shroud of the
EPD module.
Locate the brown boom wire, P/N 14500. Plug the 2-pin W/P
shroud into the mating connector on the EPD module and
plug the quick-disconnect into the mating connector on the
“Boom 1” wire on the MT-3405D harness.
NOTE: be sure to route cables away from sharp edges,
areas of high heat and moving parts. Secure all cables
firmly with plastic cable ties.
Locate the servo cable. Connect the 3-pin W/P shroud to
the 3-pin W/P tower on the EPD module. Connect the other
end of the cable to the mating connector on the MT-3405D
harness.
Locate the pump cable P/N 14501. Plug the 2-pin W/P
tower into the 2-pin W/P shroud on the EPD module. A
mating connector is supplied to connect to the motor, or
the connector on the pump cable can be removed and wire-
to-wire connection can be made. Insure that the pump is
running in the correct direction. If not, simply reverse the
wires from the pump to the pump cable.
