Appendix H: cont. Pump Driver (EPD) Module
T
he 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
c
leaned 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
b
ottom 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 SprayMate II harness.
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 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 brown wire on the
S
pra
yM
ate II 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 SprayMate II 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.
