1. GENERAL
This document provides a description of the CPS-2M
control panel. This document is organized as follows:
•Introduction
•Installation
•User’s Guide
•Appendix
Congratulations on the purchase of your CPS-2M
environmental control system. The CPS-2M provides you
with full control over static pressure and air flow resulting in
a comfortable environment for your livestock.
The CPS-2M provides microprocessor control over two
independent stages.
Each stage regulates the static pressure of a separate
room via the use of actuator motors which in turn control
the building’s air inlet baffle boards or air inlet curtains. The
CPS-2M can either use temperature (with temperature
probe 2004-1k) or for greater accuracy static pressure
(with static pressure probe model # SPS-1) as a means to
control the opening of air inlet baffle/curtains.
The CPS-2M provides you with full control over its two
stages via the use of an easy to follow display panel. All
programmable features can be customized to meet your
requirements.
Each stage has programmable temperature and static
pressure set points which are the base point for the control
of actuator motors. The delay time before actuator motors
start to run, as well as the period of time they operate are
fully programmable.

2.5 TEMPERATURE PROBES / STATIC PRESSURE SENSORS
Temperature probe and static pressure sensor use a “Class 2”
low voltage circuit. Their cable can be extended up to 500 feet
(150 meters).
Single probe temperature and static pressure connections are
illustrated in Figure 3 while temperature probe averaging
connections are illustrated in Figure 4.
2.5.1 2 Single Temperature Probe
Install a single temperature probe in an area that best reflects
the overall temperature of the room.
Connect the two leads of the temperature probe to the CPS-2
terminals labelled IN1(IN2 for probe 2), GNA and SHLD as
indicated in Figure 3.
2.5.2 Temperature Averaging
Four temperature probes are required if temperature averaging
is desired in larger rooms. Place the probes in locations that
best reflect the ambient temperature. Refer to Figure 4.
2.5.3 2 Static Pressure Sensor
To properly position a SPS-1 static pressure sensor inside the
building refer to the installation manual supplied with the unit.
Important: disconnect temperature probe, when the static
pressure sensor is used.
Connect the static pressure probe to the CPS-2M terminals
labeled IN1 (IN2 for sensor 2), PWR, GNA and SHLD as
indicated in Figure 3.
Use shielded cabling for probes . Connect the shields to
terminal “shld”. Failure to do so may result in inaccurate
readings!
Momentary power interruptions may trigger false alarms!
To avoid false alarming when the CPS-2M is connected
to an alarm system, install a time delay relay between
the CPS-2M and the alarm system.
