AMETEK 1995L Micro-Set PLS - Manual (Page 6)

Chapter 1: Introduction/Description
Installation and Maintenance Manual 2
The completely self-contained unit can operate up to 30 independent outputs (six standard) based on
the linear position of the LDT.
It offers an on line fault check which provides an automatic, in-process mechanism to verify that all
major programmable limit switch functions are operating properly. The fault check output can be
energized by activating the fault check enable input. The output is a mechanical relay with 1 N.O. and 1
N.C. contact, which remains energized during normal operation.
A programmable motion detect output will energize a relay when the LDT speed meets or
exceeds the customer-preprogrammed value.
SOFTWARE OPTION “P” ENHANCES THE SYSTEM BY OFFERING:
n Multiple Programs - Allow storage of job setups for future use. This saves time
spent reprogramming and lessens the chance of programming errors when tooling is
changed.
1.3: Controller Features and Functions
The controller is housed in an all metal case that can be panel mounted. The controller consists of a
keypad, a CPU Board, and a Power Supply I/O Board.
The following features are found on the 1995L Micro-Set.
n Display A (3) three-digit LED readout and a 10-place bar graph will show
current Linear position, programming details and output status.
n I/O Mechanical relays, AC solid-state, and DC solid-state relays are
available, and any combination can be specified. The example in the
catalog shows three AC and three DC solid-state relays being speci-
fied. There is a fixed price adder for any combination of relays other
than all mechanical (6M). The fault check relay will always be a
mechanical relay regardless of the type of output relays specified.
See Chapter 8: Specifications.
NOTE: The Bar graph will not display expansion board relay status.
As the LDT passes through the preprogrammed dwell settings, the programmer outputs can energize
solenoids, relays, or solid-state circuitry to control external circuits.
The 1995L PLS was designed for use in linear applications. It incorporates many features for safe,
efficient operation.
n Reset-to-Preset-Allows an external input i.e. prox switch to reset the PLS to a
preprogrammed value.
