Installation and Maintenance Manual

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 1995L PLS is designed to be used with a Gemco 0 to 10 Volt Analog LDT. Wiring for this system

is shown in Fig. 10-1, Fig. 10-2 and Fig. 10-3; Chapter 10: Wiring Diagrams. This wiring diagram is

applicable for all standard 1995 PLSs.

2.3: Wiring Instructions

Attach the pre-wired plug on the LDT cable to the LDT and route the shielded cable through a separate

grounded (earth ground) metal conduit to the panel and connect the mating half terminal block to the

1995L 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 60Hz - should be connected to the 1995L PLS at the AC power

terminals on the 24-place connector.
