Chapter 1: Introduction/Description
Scale Factor
Two scale factors to choose from either 360 or 1,000. On units
with P option software, the scale factor is permanently set to
360.
Electronic Offset
Fully programmable offset to any number with the scale factor.
Reset-to-Preset
Reset value is programmable to any number within the scale factor.
Motion Detector
LS6 can be programmed for either limit switch or motion detect
output.
Expansion Outputs
Programmable to accommodate up to 30 circuits.
See Section 1.2: General Information - Software Option P for more options.
Chapter 1: Introduction/Description
The 1995A Micro-Set is a fully self-contained, single-turn resolver-based programmable limit switch.
It includes a three-digit LED display, six output relays, and one fault check relay, and it is fully program-
mable for the following features:
1.1: Programmable Features
1.2: General Information
The 1995A 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 1995A consists of a resolver-based transducer, resolver-to-programmer cable assembly, and the
programmer, which provides six limit switch outputs and one fault check 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 thirty 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 1995A PLS was designed for use in rotary and/or rotary-to-linear applications. It incorporates
many features for safe, efficient operation.
