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 CM 10-2, including the alarm system and
backup devices, after installation, after changes to
the installation and every 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 CM10-2
control module. This document is organized as follows:
•Introduction
•Installation
•User’s Guide
•Appendix
1.1 DESCRIPTION
The CM10-2 is designed to drive two small diameter
fans or small loads of up to 1.5 HP (horsepower) under
the control of a MSC or an IC control system resulting
in a clean air environment for your livestock.
Small loads driving less than 0.1A such as: relays;
heater coils; or sprinkler valves may be connected to
the CM10-2
The CM10-2 provides you with automated control over
its two stages via the use of the MSC, the IC or
alternatively by manual switch control on the CM10-2
front panel.
Under MSC or IC control, the CM10-2 keeps you
constantly informed of its two stages via LED
indications.

2.1 UNPACKING
Unpack the CM10-2 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 CM10-2 control panel identified by CM10-2
printed on the faceplate of the unit
•2 cable fasteners
2.2 MOUNTING
Mount the control panel to the wall using the mounting
holes located on the flange of the control housing.
Once the CM10-2 is in place, use a screwdriver to
remove the four screws holding the faceplate to the
housing.
INSTALLATION
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 CM10-2 will operate in a temperature range of
32ºF to 120ºF (0ºC to 50ºC).
The enclosure is watertight, is not splash proof or
immersion proof. DO NOT WATER the control. Cover
the control carefully with plastic when you are
cleaning the room.
It is prohibited to use overhead cables outside the
building.

2.3 CONNECTION PROCEDURE
For the connection procedures which follow refer to
Figures 1 and 2.
2.3.1 - Cabling
Use a screwdriver to remove cable knock-outs for the
installation of cabling to the control panel.
2.3.2 - Connecting 115VAC Fans
Refer to figure 1.
•Connect L1 of the power source to terminal 1 for
fan 1and terminal 3 for fan 2.
•Connect the ground wire of the power source to the
ground wire in the housing of the unit.
•Connect the neutral side of the power source to the
neutral of fans 1 and 2.
•Connect the live lead of fan 1 to terminal 2.
•Connect the live lead of fan 2 to terminal 4.
2.3.3 - Connecting 230VAC Fans
Refer to figure 2.
•Connect L1 of the power source to terminal 1 for
fan 1 and terminal 3 for fan 2.
•Connect the ground wire of the power source to the
ground wire in the housing
•Connect L2 of the power source to the appropriate
terminals of fans 1 and 2.
•Connect the appropriate lead of fan 1 to terminal 2.
•Connect the appropriate lead of fan 2 to terminal 4.
Do not apply power to the control panel until all con-
nections have been completed!
The current draw of the load should be in the range of
0.1A to 10A.

INSTALLATION
2.3.4 - Connecting to a MSC and an IC
•Install an 18 AWG cable pair between the CM10-2,
the MSC and the IC. The cable can extend to a
maximum length of 500 feet (150m).
•Connect one end of the cable to the (+) and (-)
terminals of the CM10-2 low voltage terminal block.
Refer to the bottom left corner of figures 1 or 2.
Refer to your MSC or IC manual for further connection
procedures.
2.4 POWERING UP
Before powering up the CM10-2, attach the faceplate to
the casing of the control panel using the four screws
previously removed.
To test the unit independently of the MSC or the IC, set
the two toggle switches located on the front of the unit
to (ON). Fans 1 and 2 should both operate. If they do
not, refer to the Trouble Shooting section in the
appendix of this document.
When you have completed verifying fan operation set
both toggle switches to AUTO.

USER’S GUIDE
The CM10-2 front panel (shown above) features two 3-
position toggle switches with accompanying status
LEDs. The left toggle switch is used to control fan 1,
and the right toggle switch is used to control fan 2. A
status LED located beneath each switch indicates the
ON/OFF status of the corresponding fan as controlled
by the MSC or the IC. These status LEDs are
unaffected by the position of the toggle switches. For
example, when the MSC or the IC sends a command to
the CM10-2 for a fan to operate, the corresponding LED
will turn ON even if the toggle switch is in the ON or
OFF position.
The toggle switches permit the fans to be set in one of
three modes as follows:
OFF To turn the fans permanently off, set the
toggle switches to the OFF position.
ON To turn the fans continually on, set the
toggle switches to the ON position.
AUTO To allow the fans to operate under the
control of the MSC or the IC , set the toggle
switches to the AUTO position.
