any of the procedures contained in this manual.
•DO NOT INSTALL, REMOVE, OR REWIRE THIS
EQUIPMENT WITH POWER APPLIED. Have a qualified
electrical technician install, adjust and service this equipment.
Follow the National Electrical Code and all other applicable
electrical and safety codes, including the provisions of the
Occupational Safety and Health Act (OSHA), when installing
equipment.
•Reduce the chance of an electrical fire, shock, or explosion by
proper grounding, over-current protection, thermal protection,
and enclosure. Follow sound maintenance procedures.
Circuit potentials are at 120 VAC or 240 VAC above earth
ground. Avoid direct contact with the printed circuit board

Model PCM4 accepts a grounded or floating, bipolar, DC signal
input and generates a proportional floating output voltage. The
output of the PCM4 follows the variations of its input: it increases
as the signal increases and decreases as the signal decreases.
This output can be supplied to the speed setting circuit of a motor
drive to rotate the motor at a speed proportional to the signal
input. Because the PCM4 can follow bipolar input voltage
signals, it can drive a regenerative variable speed drive through
the complete range of motor speeds in both forward and reverse
directions.
This manual contains specifications, installation procedures,
connections, and calibration procedures for the process control
module, model PCM4. Refer to your variable speed drive user’s
manual for additional installation, operation, and troubleshooting
procedures.

Introduction

Mounting
•PCM4 components are sensitive to electrostatic fields. Avoid
contact with the circuit board directly.
•Protect the PCM4 from dirt, moisture, and accidental
contact. Provide sufficient room for access to the terminal
block.
•Mount the PCM4 away from other heat sources. Operate
within the specified ambient operating temperature range.
The operating temperature range for the PCM4 is 0°C
through 50°C.
•Prevent loose connections by avoiding excessive vibration of
the process control module board.
•Mount the PCM4 in either a horizontal or vertical plane.
•The PCM4 is mounted using 4 – 0.25 inch [6mm] standoffs.
See Figure 1, page 2 for the physical locations of these
standoffs. Use #8 panhead screws to fasten the standoffs to
the mounting surface.
Warning
Do not install, rewire, or remove this control with input
power applied. Doing so may cause fire or serious injury.
Make sure you have read and understood the Safety
Warnings before attempting installation.
