2.2: Electrical Installation
The Micro-Set is designed for use in an industrial environment and incorporates extensive transient
suppression circuitry. However, the same general installation rules should be followed that are used on
all microprocessor-based equipment. Incoming AC lines should be from a clean power source and
lines carrying computer level signals should not be routed in the same conduit as high voltage, transient-
producing circuits such as variable speed drives, welders or DC switching circuits.
The 1995B PLS is only used with a single-turn resolver. Wiring for this system is shown in Fig. 11-2,
Chapter 11: Wiring Diagrams. This wiring diagram is applicable for all standard 1995 PLSs.
2.3: Wiring Instructions
Attach the pre-wired plug on the resolver transducer cable to the transducer and route the shielded
cable through a separate grounded (earth ground) metal conduit to the panel. Connect the mating half
terminal block to the 1995B PLS. Be sure the shield wire is connected to Pin 1 of the 16-place
connector.
When extension to the factory supplied cable is necessary, a junction box should be used to connect the
wire leads and the cable shields from one cable to the other. The cable shield should be grounded at the
1995 Micro-Set only.
AC line voltage - 115V AC + 10% 50-60 Hz - should be connected to the 1995B PLS at the AC
power terminals on the 24-place connector.
(B) Combination mechanical cam/resolver systems. Intended as bolt-in replacements to
existing switches. The cam/resolver combination unit should be coupled where the
existing limit switch is located. Wire and adjust the mechanical cams in accordance with
the original press manufacturers specifications and wire the resolver cable to the
controller.
