1.2 Introduction
Congratulations on your excellent choice of purchasing an Farm Center Pro/Farm Master Pro!
In order to realize the full benefit from this product it is important that it is installed, commissioned and
operated correctly. Before installation or using the fan, this manual should be studied carefully. It is also
recommended that it is kept safely for future reference. The manual is intended as a reference for
installation, commissioning and day-to-day operation of the Munters Controllers.
1.3 Notes
Date of release: July 2010
Munters cannot guarantee to inform users about the changes or to distribute new manuals to them.
NOTE All rights reserved. No part of this manual may be reproduced in any manner whatsoever
without the expressed written permission of Munters. The contents of this manual are subject to
change without notice.
Always connect temperature and sensor shields to earth ground. Avoid mixing high voltage
wiring with sensor and low voltage wiring.
•
Keep the controller as far as possible from heavy contactor boxes and other sources of
electrical interference.
•
Do not connect communication wire shields, which go from one house to another at both ends.
Connect them at one end only. Connection at both ends can cause ground loop currents to
flow, which reduce reliability.
•
The COM connection for communications is not the shield wire. The COM, RX and TX wires
must connect to each other at all controllers.
2.2 Checking the Battery Level
Check the battery once a year. The output must be 2.7 volts (minimum). Authorized personnel only must
replace the battery if the output is below the minimum required level or every five years.
2.3 Filtering
If this installation includes a power inverter to drive variable speed fans, install an EMI filter in front of the
inverter, according to the specifications provided by the inverter manufacturer. Referto the inverter
documentation.
2.4 Frequency Inverters
Frequency inverters can cause severe electrical and electromagnetic interference. Therefore, when
employing a frequency inverter, it is critical that you carefully follow the manufacturer's installation
instructions.
In particular verify:
•
that the cable shielding between the inverter and any motor meets industry standards
•
proper grounding of the inverter's chassis and motor power cable
•
proper grounding of low voltage cable shield wire
•
that the controller and inverter cables are kept in separate conduits or wire bundles

Farm Master Pro
3.2.1 F
Farm Center Pro provides you maximum capability with minimal complexity in programming and
controlling up to 10 Farm Master Pro units.
Farm Center Pro is the ultimate pig house controller. Equipped with an easy programming interface, it
provides programmable outputs for all major features and an advanced graphic user interface that
provides simple, fast navigation, informative main screen, display feedback on the programming and
device status.
ARM CENTER PRO
The Farm Center Pro communicates with up to ten Farm Master Pro units to access history, collect events
and alarms for each and all relevant data up to 100 days.
3.2.2 F
ARM MASTER PRO
Farm Master Pro is Munters’s latest advance in environmental controllers specially designed for the pig
house industry.
The user-friendly has high performance and quick response time. Farm Master Pro features accurate
temperature and humidity sensors, secure transmission of data even in noisy environments and the added
convenience of eight output relays as well as four analog outputs.
Each Farm Master Pro can operate independently in case of Farm Center Pro malfunction or loss of
power. Using an internal battery when the Farm Master Pro is operating “alone”, there is no history
collection or possibility to change parameters.
There are three Farm Master Pro models:
•
: No variable speed
•
: One channel variable speed
•
: Two channels variable speed

Communication with up to ten Farm Master Pro units
In case of an alarm, a blinking message appears on the main screens in addition to the
siren. Pressing "0" on the main screen, when the alarm message is on, directs you to the
room with the alarm. Resetting the alarm is possible, but it only stops the siren and not the
screen message. Only by fixing the problem stops the message.
NOTE Once communication is off there is no history accumulation in the Farm Center Pro.
A dotted lined square indicates N/A (not available).

4 Mechanical Installation Guide
These units must be installed by an authorized electrician. Power must be disconnected to
avoid electrical shock and damage.
To avoid exposing the controllers to harmful gases or high humidity, it is recommended to
install it in the service room.
NOTE Installation Category (Over voltage Category) II
•
The power supply to the controller should be protected by 10 amps circuit breaker
All electrical connections should comply with National Electrical code (NEC)
•
1. Screw the metal sheet on the back of the box using the 4 supplied screws. Mount the Farm
Master Pro through the mounting holes (see next page).
2. Open the enclosure lid by unfastening the four screws.
3. Drill holes at bottom of the box and place cable holders.
4. Place the required cables through the cable holders at the bottom of the unit. Connect the wires
according to the wiring diagrams.
5. Make sure that you use wires large enough for the load of the variable speed.
6. To connect temperature and humidity sensors use shielded two or four conductor #18-#24
gauge cables. Connect the shields to the Ground metal strip. Do not connect the shields to more
than one point, or you may induce ground loop currents.
7. Close the Farm Master Pro enclosure lid carefully and tightly. Use RTV silicon or equivalent
sealant to seal the cable holders.
8. After installation is completed, operate the Farm Master Pro for a few hours and re- check for
proper operation.
4.1 Environmental Protection
packaging should be sorted for environmental-friendly recycling. The plastic components
are labeled for categorized recycling.
4.2 Sensors and Shielded Wiring
•
For long shielded wires, connect the shield to ground at
•
From the ground terminal, run a heavy wire directly to the ground rod. It is acceptable, if
necessary, to run the heavy ground wire to the electrical service grounding system rather than
directly to the ground rod.
•
Do not use light wires for these ground connections. They must carry heavy lightning currents,
sometimes exceeding thousands of amperes. Certainly, do not use the shielding of sensor and
low voltage wiring for this purpose.
Ensure that all ground connections go to a single local point. When lightning strikes, grounds a
meter or two apart will be at significantly different voltages. If you have several electronic
boxes with individual grounds, connect all these together to a single point (If Possible),
preferably to the surge protector ground. This should continue to the ground rod or the
electrical service. In particular, avoid grounding any controls remotely through shield wiring.
•
Do not use shields to create a path for lightning. For long shield wires, such as building to
building runs, connect the shield to ground at
only, to reduce the chance of
conducting lightning from one building to another.
•
When splicing sensors to longer wires, ensure that the splice is
. Use adhesive lined
heat shrink (marine grade) to make waterproof connections.
•
Use a good compression connector for splicing. This is better than soldering. Do not simply
twist wires together and then cover with electrical tape.
•
Keep sensor wiring separate from other power distribution and high voltage wiring. Ensure that
lightning on other wiring will not transfer to the sensors.
•
Install outside temperature sensors so that the sun will not cause false readings, and so that
exhaust air from the building will not affect the sensor.
4.3 Installation and Electrical Connections
•
Install computerized electronic controls at least one meter (three feet) away from interference
sources such as high voltage wiring to motors, variable speed, light dimmers, relays.
•
Install electronic controls in a separate ventilated control room that is protected from extreme
temperatures and dirty environments. Place the controls so that the operators can conveniently
use the control and read indicators and displays.
•
Give your installation a professional appearance, with all wiring in conduit or neatly installed.
Keep low voltage wires separate from high voltage wires.
•
Use shielded wiring for low level signals. For buried wiring (building to building runs) use high
grade jell filled cables that are impervious to moisture.
•
Seal cable entry points and control boxes to prevent contamination and corrosion. If you use
silicon sealant with acetic acid cure, keep the control open and ventilated until cured.
Otherwise, the acetic acid will attack the metal parts, including circuitry.
•
Drill cable entry holes on the bottom of the box only.
