Although the manufacturer has made every effort to
ensure the accuracy of the information contained herein,
this document is subject to change without notice due to
ongoing product development.
WARNINGS AND PRECAUTIONS
Equipment , probe failure, blown fuses and/or tripped
breakers may prove harmful to the contents of the
building. Therefore it is strongly recommended to install
backup devices and alarm or warning devices. Spare
equipment should also be available at the owner’s site.
Equipment manufactured by the manufacturer is
protected against normal line surges. High surges caused
by thunder storms or power supply equipment may
damage this equipment. For added security against line
voltage surges it is recommended that surge and noise
suppression devices be installed at the electrical
distribution panel. Use of shielded cable for probes is
recommended for protection against lightning. These
devices are available from most electrical supply
distributors.
RECOMMENDATIONS
The manufacturer recommends that all installation
procedures described herein be performed by a qualified
electrician or installation technician. Further more the
manufacturer recommends to test all the functions and
equipment connected to the CPS, including the alarm
system and backup devices, after installation, after
change to the installation and once a month after that.
Fuse verification and replacement, as well as the proper
setting of control values shall be the responsibility of the
owner of this equipment.

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.

2.1 UNPACKING
Unpack the CPS-2M from its box and inspect contents for
damage. Should the contents appear to be damaged,
contact your local distributor for return material procedures.
The package should contain the following standard items:
•1 CPS-2M control panel identified by CPS-2M
•3 cable fasteners
•2 temperature probes
The following optional items may be included:
•3 additional temperature probes per zone for
temperature averaging
•2 SPS-1 static pressure sensor.
2.2 MOUNTING
Mount the CPS-2M to the wall using the mounting holes
located on the flange of the control housing.
The manufacturer recommends that the installation
instructions which follow be adhered to as closely as
possible, and all work be performed by a certified
electrician. Failure to do so may void the warranty!
To limit the unit’s exposure to noxious gases install the
unit in a hallway.
Make certain that the unit is mounted right side up with
the cable entry holes facing down.
The CPS-2M will operate in a temperature range of 42°F -
111 °F (5.5 °C - 44 °C).
The enclosure is watertight, it is not splash proof or
immersion proof. DO NOT WATER the control. Cover
carefully with plastic when you are clean the room.
It is prohibited to use overhead cables outside the
building.
Mounting hardware is not shipped with the unit.
CHAPTER 2 - INSTALLATION

CPS-2M
Once the CPS-2M is in place, use a screwdriver to remove
the six screws holding the faceplate to the housing.
2.3 SWITCH SETTING
The CPS-2M is configured for a variety of options via two
switches: the line voltage selector switch, and the software
settings DIP switch. These switches are described in the
following two sections.
2.3.1 - Line Voltage Selector Switch
This switch is located on the surface of the main (bottom)
board and adapts the CPS-2M for 115 VAC or 230 VAC
line voltage. The manufacturer set the switch to 230 VAC.
If you wish to use it on 115 VAC you have to select to 115
VAC before turning on the power
Refer to figures 1 through 2.
2.3.2 - Software Settings DIP Switch
This switch is located at the rear of the CPS-2M faceplate
and adjusts the following options.

Switch 1 Fahrenheit or Celsius display on the CPS-
2M
Switch 2 Locks or unlocks your settings. All settings
except for main set point, record low, and
record high are locked while this switch is
off.
Switch 3 Increases static pressure sensitivity with DIP
switch set to OFF. (The static pressure
reading will react faster with High
sensitivity).
Switch 4 Static pressure mode or temperature mode.

CHAPTER 2 - INSTALLATION
2.4 CONNECTION PROCEDURE
2.4.1 - Input power
Use a screwdriver to remove cable knock-outs for the
installation of cabling to the control panel.
2.4.1.1 - 115 VAC
Make certain that the line voltage selector switch is set
to 115 VAC. Connect the live of the power cable to
terminal 12 and neutral of the power cable to terminal 11
on the main (bottom) board.
2.4.1.2 - 230 VAC
Make certain that the line voltage selector switch is set
to 230 VAC. Connect L1 of the power cable to terminal 12
and L2 of the powers cable to terminal 11 on the main
(bottom) board.
2.4.2 - Stage one actuator motor
Stage 1 provides two dry contacts which control a linear
actuator motor used to operate an air inlet baffle board or
air inlet curtain. One dry contact is used to operate the
motor winding which reduces the air opening, and one dry
contact is used to operate the motor winding which
increases the air opening. The current rating of these dry
contacts are 6 Amps (inductive). Refer to figure 1 and 2.
2.4.3 - Stage two actuator motor
Stage 2 provides two dry contacts which control a linear
actuator motor used to operate an air inlet baffle board or
air inlet curtain. One dry contact closure is used to operate
the motor winding which reduces the air opening, and one
dry contact closure is used to operate the motor winding
which increases the air opening. The current rating of
these dry contacts are 6 Amps (inductive). Refer to figure 1
and
To connect a 2-wire DC actuator, see figure 0
To connect two actuators on the same output, see figure
1a.
To connect a three phase motor, see figure 6.
Do not apply power to the CPS-2M until all connections
have been completed!

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.
