Chapter 1: Introduction/Description
The 1995B Micro-Set is a fully self-contained, single-turn resolver-based programmable limit switch.
It includes a three-digit LED display, five output relays, and one fault check relay, and it is fully pro-
grammable for the following features:
1.1: Programmable Features
1.2: General Information
The 1995B Micro-Set is a fully self-contained, microcomputer-based Programmable Limit Switch
(PLS) with a convenient keypad for programming each independent output circuit to open or close at
the desired settings. This system allows precise position control of rotary motion.
A 1995B consists of a resolver-based transducer, resolver-to-programmer cable assembly, and the
programmer, which provides five limit switch outputs, one fault check output and one brake monitor
output. The optional output expansion modules will add six additional limit switch outputs per module,
and up to four expansion modules can be driven by the programmer, for a total of twenty-nine limit
switch outputs.
The single-turn resolver transducer generates a ratiometric analog signal representing an absolute rotary
position. This ratiometric signal is converted to a digital signal at the Micro-Set. A microprocessor
calculates and/or converts these signals based on user-programmed data.
As the transducer passes through the preprogrammed dwell settings, the programmer outputs can
energize solenoids, relays, or solid-state circuitry to control external circuits.
The 1995B PLS was designed for use in rotary and/or rotary-to-linear applications. It incorporates
many features for safe, efficient operation.
The completely self-contained unit can operate up to 29 independent outputs (five standard) based on
the rotary position of the resolver.
