Chapter 1: Introduction/Description
The 1995L Micro-Set is a fully self-contained, 0 - 10 Volt input programmable limit switch. It includes
a three-digit LED display, six output relays, and one fault check relay, and it is fully programmable for
the following features:
1.1: Programmable Features
1.2: General Information
The 1995L 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 linear motion.
A 1995L consists of an LTD (Linear Displacement Transducer) , LDT 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 expan-
sion modules can be driven by the programmer, for a total of thirty limit switch outputs.
The position input into this PLS is a 0 to 10 VDC analog signal usually provided by a Gemco LDT. The
0 to 10 volts is generated by the LDT over its active stroke. The PLS will read out position directly in
inches if the scale factor entered is the active stroke of the LDT (in inches).
The LDT generates a 0 to 10 Volt D.C. analog signal representing an absolute Linear position. This
Analog signal is converted to a digital signal at the Micro-Set. A microprocessor calculates and/or
converts these signals based on user-programmed data.
