40 AMP PWM ELECTRIC MOTOR DRIVER
PN# 18022
40 AMP MAXIMUM
(RED OR WHITE)
(BLACK)
The Pump Driver Module (EMD) replaces the servo valve.
System ow is controlled by regulang the pump speed
via a PWM signal to the EMD.
NOTE: This unit will ONLY work with PWM (Pulse Width
Modulated) Control drives. Set the PWM frequency of
your controller to 150 Hz.
MODULE INSTALLATION
Posion the EMD where wiring will work the best.
Extension cables are available. Secure the EMD to the
equipment, fastening with screws, using the holes in
the mounng anges.
ELECTRIC INSTALLATION
This secon explains how to hook-up your EMD to a
12-volt power connecon, and how to connect your
EMD to your controller harness.
The EMD MUST be connected to a 12-volt DC negave
ground electrical system.
POWER BATTERY CONNECTION
Locate the power cable and route to the baery. In rout-
ing cable avoid areas where the cable may be subjected
to abrasion or excessive heat. Aach the BLACK wire to
ground. See Illustraon to the upper right. Be sure there
is a good metal-to-metal contact. Connect the RED (or
WHITE) wire to the posive baery terminal. Connect
the power to the EMD by plugging the 2-Pin M/P 480
Tower on the power cable into the 2-Pin M/P 480 Shroud
of the EMD module.
NOTE: Be sure to route cables away from sharp
edges, areas of high heat and moving parts.
Secure all cables rmly with plasc cable es.
SIGNAL AND MOTOR CONNECTIONS
Connect the other end of the cable to the mang
connector on the controller harness using Adapter
Cable P/N 53556 if required.
Locate the pump cable or “y” harness for dual pump
system. Plug the 2-pin M/P 480 Shroud into the 2-pin
M/P 480 Tower on the EMD module. Connect the other
end to the pump. Insure that the pump is running in the
correct direcon. If not, simply reverse the wires from
the pump to the pump cable.
