EATON CORPORATION Fluid Power
EP Control for Medium Duty 72400 Piston Pumps
Installation 04-10-0003-EN-0901 September 2001
Introduction
The following information describes the installation of the Electronic Proportional
(EP) Control for Eaton®Medium Duty 72400 piston pumps. Review this information
to become familiar with the procedures required before beginning any installation.
In order to assure the most reliable installation
and operation of any electronic control, proper
component selection and installation procedures
must be followed with respect to interconnection wiring harnesses, input
command signal devices, fusing, and input power switching.
Appropriate industry practices must be followed to prevent damage of and
shorting of all electrical and electronic components caused by environmental
hazards and application specific hazards. Typical hazards that damage the
wiring harnesses or other components are abrasion, moving objects, and heat
from the engine or exhaust system. Moisture can damage poorly sealed
connectors and/or components, causing short circuits and other problems like
corrosion.
A switch must be installed in line with (+ battery) power to the electronic
module, so that power may quickly be disconnected in case of emergency
(component failure or inadvertent commands). A fuse rated at the maximum
module operating current (3 Amp) must be installed in the + battery line to the
electronic module.
All the electrical connections to the EP Control electronic module must be
disconnected prior to performing any electrical welding on the vehicle or
machine.The electronic module and/or the hydraulic pump are not to be
used as a connection point for electrical welding equipment.
During initial start-up and/or checkout of the machine after service, the
machine must be placed on jack stands to prevent inadvertent movement.
The reliable operation and suitability of this product is dependent upon how
it is applied and the other components used in the system. The system
integrator must review all aspects of the application and all of the
components used to assure proper operation and reliability.
