Section 4 INSTALLATION
4.1 Component Mounting
The System 2500 PLS consists of three major components; the Operator Interface Terminal
(OIT), the Logic Unit, and the Resolver Unit. These components are identified in Figure 1. In
order for the System 2500 to function correctly, these major components must be properly
installed and connected. Please read this entire section before attempting installation.
The OIT must be mounted in a position that is
easily accessible and viewable by the operator.
Operator communication to the System 2500 PLS
is via the OIT. The operator must be able to
actuate the OIT keypad and read the OIT liquid
crystal display. It is desirable for the operator to be
able to view the OIT display from the position
which he normally operates the machine. The OIT
liquid crystal display is designed to be viewed from
the bottom of the display. If the OIT is to be
mounted in a vertical plane, it must be mounted
slightly above the operator's eye level. If the OIT is
to be mounted on a sloped surface, it must be
mounted so that the operator's line of sight is from
bottom of the liquid crystal display. Please refer to
Figure 20.
The required cutout dimensions for the OIT are
shown in Figure 21. The desired wire entry for the
OIT is from the bottom of the unit.
The mounting dimensions for the Logic Unit are illustrated in Figure 22. This unit must be
mounted in a suitable enclosure which will prevent the entry of oil and dirt.
The System 2500 PLS can be purchased with the OIT and Logic Unit already mounted in an
enclosure. This unit must be mounted so that the OIT is accessible and viewable to the operator
as described above. Space must be provided below the enclosure to allow for wire entry to the
bottom of the enclosure. If the enclosure is mounted to the machine frame suitable shock mounts
should be used.
The resolver unit must be driven by the machine crankshaft. It is preferable for the unit to be
driven in a 1:1 ratio by the machine crankshaft. If necessary the resolver may be driven by high
