Chapter 2: Installation
This section describes the installation and wiring of a standard 1995B Micro-Set PLS. Changes to
these instructions should be made as necessary if special options and/or equipment are used.
The 1995B Micro-Set should be installed in an area free of water spray, corrosive gases, flying chips
or other foreign matter. The operating temperature should be between 32 and 125 degrees Fahrenheit,
with less than 95% relative humidity.
2.1: Mechanical Installation
Mounting the 1995 Micro-Set PLS
The 1995B Micro-Set PLS is designed to be panel mounted. The face of the 1995B can be affected
by water and/or oil spray. Provisions should be made to protect the face of the unit from spraying or
splashing.
Panel cutouts, mounting holes, and sizes for each component are shown on Pages 6 and 7 of the 1995B
catalog section.
The controller should be mounted in the appropriate panel cutout and securely bolted into place using
the four (4) 3/16" diameter mounting holes.
NOTE: In instances where the 1995B is being mounted directly on a mechanical stamping press, care
should be taken to isolate the controller from shock load and vibration.
It is always good design practice to mount the controller in the enclosure as far away from the motor
starters and control relays as possible to minimize the effects of electromagnetic interference (EMI).
Interconnecting wiring also should be routed to minimize EMI coupling.
Mounting the Transducer
The proper mounting of the resolver transducer is critical to ensure the systems accuracy. There are
two resolver transducers available.
(A) Standard foot mount resolver transducer. The foot mount resolver transducer should be
mounted in an area free of excessive shock and vibration (as is commonly seen by
mounting plates that extend over the edge of the press). The resolver transducer should
be connected in a 1:1 ratio with the crank. If a double-ended cam limit switch is
available, it is preferable to mount off of the rear shaft
NOTE: The Micro-set programmable limits are not control reliable for the clutch/brake circuits.
Mechanical cam limits must be used for these circuits.
