2 Introduction to the AC-2000 3G

This document describes the AC-2000 3G Precision Mode operation.

Computerized Electronic Controllers such as the AC-2000 3G advance the producer’s ability to grow
high quality eggs by accurately controlling the environment. Instead of struggling with individual
thermostats for heat zones and ventilation, AC-2000 3G brings them all together into one convenient
place with great accuracy. The AC-2000 3G optimizes and precisely applies your equipment and energy
sources to most benefit from the accuracy of your computer and sensors.

The AC-2000 3G coordinates your ventilation equipment in precise levels of ventilation to provide the
optimal fresh air balanced with heating costs. The light and feed clocks provide additional channels for
greater capability. Besides advanced Cooling Pad methods, you benefit from superior stir fan programs
to recover ceiling heat and other features. Precision Mode’s additional features enable you to improve
your profitability significantly.

AC-2000 3G provides a variety of management and history utilities. You can choose from simple
overviews, or fully detailed

by the minute

records of minimum, maximum and average temperatures for
each individual sensor. The unique Table of Events records the moment of every significant action taken
by the AC-2000 3G and, optionally, its operator.

YCLE HEATERS | SET DEFINITIONS

Heat Cycle means providing heat in conjunction with the ventilation system during minimum ventilation
cycles, using heaters and fans connected to relays. When enabled, heaters operate during the fans’
cycle off time (as defined in the Levels of Ventilation Cycle Timer On and Off parameters). How does it
work?

Between the Heat Temperature and the differential temperature, heaters do not operate. When the
temperature goes below the Heat Off temperature minus the Low Heat Differential:

•

Heaters begin to operate when the exhaust or tunnel fans are off. Heaters operate for the
Minimum On Time.

•

If the temperature continues to drop, heaters operate for longer periods of time, up to the
Maximum On Time (defined in Levels of Ventilation).

•

AC-2000 3G automatically generates a curve.

In this example:

•

Temperature Curve Heat Off is 78°.

•

Low Heat Differential is 1°.

•

High Heat Differential is 8°.

•

Minimum On time is 30 seconds.

•

Cycle Off time is 270 seconds.

3.1.4.1 Linear Heat

When Linear Mode is enabled:

•

Between the Heat Temperature and the Target temperature, heaters do not operate (meaning,
the output voltage is 0).

•

Between the Heat Temperature and the Low Difference Below Heat, heaters operate at the
minimum voltage output.

•

If the temperature continues to drop, the voltage output increases until it reaches the maximum
voltage output at the High Difference below Heat.

In this example:

•

Target Temperature is 80°

•

Temperature Curve Heat Off is 78°.

•

Low Heat Differential is 1°.

•

High Heat Differential is 8°.

o

If the temperature is between 77° to 78°, the output voltage is the minimum voltage

defined in Installation > Analog Output (1 volt in this example).

o

If the temperature continues to drop, the output voltage increases until it reaches the

maximum voltage defined in Installation > Analog Output. Output increases or
decreases to keep the temperature within the Target Temperature and Heat Off band.

3.1.4.2 Proportional Heat

Proportional Heat works in manner similar to Linear Mode. The difference is that Proportional Heat
features a delay time.

•

When the temperature falls below the user-defined point, the heaters begin operating at their
minimum output.

•

After the response time passes, AC-2000 3G checks the temperature. If it is still below the
defined point, AC-2000 3G increases the voltage by a certain amount (this amount of the
increase cannot be changed).

•

After the response time passes, the process is repeated until heaters operate at their maximum
output.

3.2 Introduction to Humidity, Ammonia, and CO2 Treatment

AC-2000 3G provides various options to controlling the humidity, CO2, and ammonia levels.

•

None: No treatment is provided.

•

Level: Ventilation levels increase for a designated amount of time.

•

Tunnel or exhaust fan: A designated fan turns on for a designated amount of time. The amount
of air blown into the house is greater than that provided by an increase in ventilation level.

•

Increase in air / weight: The total amount of air that fans need to provide increases by a user
defined amount. Fan stay on until CO2, humidity, or ammonia levels fall to their defined levels.
This option is only available when using Minimum Ventilation by Weight.

•

Humidity treatment by heat: In cold air situations, heaters can be turned on to lower the
relative humidity.

If there is a contradiction between CO2, humidity, and ammonia treatments:

•

Ammonia treatment has priority over CO2 treatment.

•

C02 treatment has priority over humidity treatment.

•

Increase in air / weight has priority over other treatments.

•

Humidity treatment by heat takes priority over increasing the ventilation.

3.3 Humidity Treatment

Humidity treatment forces an increase in ventilation level when the humidity is too high. It holds the
increase for ‘Duration Seconds’, and checks back after ‘Interval Minutes’ for another increase. After the
duration, the ventilation level comes back down automatically.

The By Weight option enables controlling the minimum air flow depending on the number of birds, their
weight and the current outside temperature. When using the Weight option, AC-2000 3G takes several
parameters and calculates the air speed, level of ventilation and cycle time needed to supply the required
volume. As opposed to the other ventilation methods, the Weight option is dynamic, with the ventilation
changing according to the current parameters (quantity of air required, weight of birds and number of
birds, outside air temperature). In addition, Ventilation By Weight sends out an alarm if the current
ventilation is below the minimum required level.

to Temperature Curve, page 9) that defines outside temperature as Warm in the Soft Min/Max
table. For example, if the Heat Temperature is 78° F, Warm Temp. – Diff Below Heat is 2.0,
than the outside temperature is defined as warm at 76° F.

•

Cold Temperature: Outside temperature (or below) at which Air per Kg/Lb (Cold) capacity
is reached.

When the outside temperature is between the Warm and Cold Temperature, the flow rate is
calculated at a proportional rate.

•

Air Change: As the temperature rises from the Cold Temperature parameter to the Heat
Temperature (or drops from the Heat Temperature to the Cold Temperature parameter), the
minimal air volume rises/falls proportionally. Air Change defines the minimal change in air
temperature that must takes place to cause a change in the air supply.

•

Fan Cycle Time: The total amount of time that the fans operate while operating under Minimum
Ventilation. During this time, the fans supply the required volume of air at the minimum
ventilation level required. AC-2000 3G adjusts the minimum ON time and OFF time as
needed. If the fans cannot supply the required volume at a particular level of ventilation, the
controller automatically adjusts the minimum ventilation level.

o

Minimum ON Time in Vent Cycle: The minimum amount of time that the fans operate

during a cycle. The controller adjusts the actual fan time as needed.

o

Minimum OFF Time in Vent Cycle: The minimum amount of time that the fans do not

operate during a cycle. The controller adjusts the actual fan time as needed.

As the temperature rises, the actual Minimum OFF Time decreases until it reaches the minimum time.
Only then does the Minimum On Time begin to rise.

NOTE If the temperature goes above the Band Temperature, Power Ventilation begins and times are

adjusted accordingly.

•

Air Change By Humidity/CO2/Ammon%: As the humidity, CO2, or ammonia levels rise
above the levels specified in Humidity Treatment, CO2 Treatment, or Ammonia Treatment the
minimal air volume rises proportionally. Air Change By Humidity/CO2/Ammon% defines the
minimal change in in these levels that must take place to cause an increase in the air supply.

•

Air Per Weight Curve Mode: By default, Air per Kilo/Lb has two data points: cold
temperature and warm. If desired, the user can add an additional intermediate (computer
defined) data point which is between the two default points. This point determines the quantity
of air to be distributed when the temperature reaches the midpoint between the cold and warm

3.9 Ammonia Treatment

Ammonia treatment forces an increase in ventilation level when the ammonia level is too high. To prevent
fans changing their ventilation too often, treatment begins after a user-defined delay. The user also
defines the treatment duration.

After the treatment, the ventilation level may come back down automatically if the house temperature is
below the target temperature. Otherwise, the ventilation level does not change. If during treatment, the
ammonia level drops below the Stop Value parameter, the ventilation level automatically returns to that
level used before ammonia treatment began.

Levels of Ventilation, page

DEVICE SETTING

4 Device Menu

The AC-2000 3G can have many closely spaced levels of ventilation enabling it to find the optimum
average airflow for the poultry facility. Many of the levels are at exactly the same temperature setting, so
there may be a question as to how the AC-2000 3G chooses the correct level. The menus in this section
apply levels to ventilation, variable speed fans, curtains, and so on. The levels in the various menus are
consistent with each other so that a level in one menu corresponds with that level in any other menu.

The rules that apply here are:

•

Rule 1: If the temperature is at target (in the Happy Zone) stay at the current level.

•

Rule 2: If the temperature moves outside the Happy Zone wait for a few minutes.

Rule 3: After waiting increase or decrease level appropriately.

•

You can find the ‘patience’ factors under HELP | SET in this menu. They are the increase level delay and
decrease level delay parameters. The factory default values are 180 seconds for an increase and 60
seconds for a decrease. The factory default values biases the AC-2000 3G slightly toward warmer
temperatures, as would be appropriate for young birds. The level increase delay is longer than the level
decrease delay. You may wish to reverse these values by the time you have market age broilers, since
they are more sensitive to heat stress than to cold.

Although many of the levels have 0.0 differential temperatures, certain levels should have differentials to
account for wind chill on the birds. The first tunnel level accounts for wind chill by switching to the tunnel
temperature instead of target temperature. Higher tunnel levels require an additional wind chill because
of the increased airflow.

In addition, the last few levels before entering tunnel can form a transitional region. You may want to
build differentials from target temperature just before the first tunnel level.

The controller obeys both the time delay rules and the differential temperature rules when changing levels.
Tunnel exit has several additional rules, such as outside temperature restriction and the tunnel exit delay
described under HELP | SET. In addition, there are Cool Down and change to Min Vent on reaching the
Heat temperature features described in Control | Temperature Curve | HELP | Set parameters.

4.1 Levels of Ventilation

The Ventilation table provides up to 30 ventilation levels. To program this table, start with the minimum
ventilation used in the first level and increase ventilation gradually. A reasonable rule of thumb is to
increase the airflow about 25% at each level. Increases in airflow up to 50% work satisfactorily with
factory default settings.

IND CHILL

AC-2000 3G can take into consideration the wind chill factor when making certain calculations related to
the temperature. In effect, the wind chill factor acts as the temperature differential. When enabled, AC­2000 3G determines the “calculated temperature (actual temperature – wind chill temperature) and uses
this temperature:

•

When calculating the Tunnel Mode level up/down algorithms

•

When operating the Cool Pad (if enabled in System Variables; refer to Operate Cool Pad,
page 40.

The Wind Chill factor influences controller operation from the 1st tunnel level.

NOTE The actual temperature: 1) determines the entry and exit into Tunnel Mode 2) controls the

fogger.

Parameters:

•

Wind Chill: Enable this parameter to include the wind chill factor in ventilation calculations.
Default = No.

•

Wind Chill Limit: Maximum wind chill factor value. Default = 8° C.

•

RH Effect: The decrease in temperature caused by an increase in relative humidity. Default is

0.26° C.

The Relative Humidity Effect parameter enables including the relative humidity (RH) in the wind chill factor
calculations. A rise in relative humidity reduces the wind chill factor. How does it work?

o

There is no effect below 40% relative humidity.

The user determines the increase in temperature for every 5% increase in relative

humidity.

 The default increase is 0.26° C; meaning that between 40.1% - 45% relative

humidity, the wind chill factor decreases by 0.26° C. Between 45.1% - 50%, the
wind chill factor decreases by 0.52° C, twice the default level. Between 50.1% ­55%, the decrease is 0.78° C, three times the default level, and so on.

 The user can set the temperature increase as required.
 To disable this feature, enter '0'

4.2 Variable Speed Fan Levels

In the Variable Speed Fan Level table set the speed in percentages for up to two groups of fans by level.
Several kinds of speed controllers are supported, such as TRIAC Control and Variable Frequency 3 Phase
drives.

Difference Between Cool Pads Stage: AC-2000 3G supports four cooling pad stages. The

controller activates the first stage when the temperature reaches the Tunnel Temperature
(

) plus the Tunnel Differentiation (set in the Cool Pad screen). Each
additional stage begins when the temperature reaches the Tunnel Temperature plus the Tunnel
Differentiation plus this differentiation.

For example, if:

o

Tunnel Diff = 2

o

Diff between Cool Pads Stage = 3

Stage 1 starts at 82°, Stage 2 at 85°, Stage 3 at 88°, and Stage 4 at 91°.

midnight. This program repeats until day 25.

 From day 25 the on/off lights stay off, and the dimmer lights provide dim light

during the on periods, and go out fully for two periods of darkness. The dark
periods total 6 hours, being from midnight to 03:00 AM and from 08:00 PM
(20:00) to 11:00 PM (23:00).

Water on Demand Alarms

High/Low Pressure Diff (PSI): Sends an alarm when the difference between the current WOD
pressure and the defined pressure reaches these levels. 0 means that the alarm is disabled.

Shutdown Pressure Diff (PSI): Shuts down the Water on Demand system when the pressure
reaches this level.

o

Shutdown pressure must be equal to or higher than the High/Low Pressure Difference.

o

However, to disable this alarm set it to 0 (zero), even if the High/Low Pressure is

above 0.

Feed Alarms

Allow Feed Alarm From/To: Set a starting time from which the controller can send feed
shortage alarms.

Bin 1/2 Low Feed Alarm Limit: Alarm if feed in Bin 1/2 is below this limit and time is between
From and To limits.

Feed Alarm Limit (per hour): An alarm is generated if the feed flow is greater than this
amount. This alarm is activated when a problem arises inside the barn (as opposed to when
something happens to the feed scale).

Water Overflow Alarms

•

According to Light Table: Change overflow alarm level when the lights are off.

•

First Day: Overflow on the FIRST day applies to the first day operation. You can define a first
day at which to start increasing the overflow limit automatically. Days prior to the ‘First Day’ use
the First Day overflow limit; days following the first day have an incremental curve toward the
LAST DAY OVERFLOW parameter setting.

•

Overflow on First Day: Number of gallons/liters per minute that generate an overflow alarm
on the first day.

•

Last Day: Set the last day for the Overflow curve.

•

Overflow on Last Day: Overflow (Gallons/Liters) on the last day sets the maximum overflow
limit will be continued after that day.

•

Overflow At Dark: Select overflow limit. When it is dark, controller checks every minute.

•

Overflow Alarm Delay: Define delay time before the controller generates an overflow alarm.

•

Extra Delay At Light Start: When the first light appears, define the amount of minutes before
the controller begins to operate according to the set Overflow for that day.

•

Fogger Water Overflow: Define the water overflow for foggers (per minute).

Water Shortage Alarms

•

Allow Water Shortage Alarm From/To: Set the period for which the controller generates
water shortage alarms.

© Munters AB, 2021 54

•

Shortage During Lights Off: Select whether water shortage alarm should be disabled when all
lights are out.

•

Quantity for Shortage: Minimum flow rate that must be maintained or a water shortage alarm
is generated.

•

Shortage Alarm Delay: Minimum period of time that the shortage must extend through before
generating an alarm.

•

Shortage Start Day: Define on what day shortage alarms begin. This parameter prevents false
alarms caused by young birds low water usage. Default: 0 (meaning alarms function normally
throughout the growth cycle).

Bird Scales Alarms

•

Allow Bird Scale Alarms From/To: Set time frame for which the controller begins and ends
generating alarms for the bird scale.

Auxiliary Alarms

•

Assign auxiliary alarms in the Install menu. Note that digital sensors, auxiliary alarm input with
related relay must always match their relay status.

•

Related Relay For Aux Alarm 1/2/3/4: Relay for Auxiliary Alarm 1/2/3/4.

•

AUX. Alarm Delay (sec): Separate from the Global Alarm Delay. If there is a dry contact, the
alarm is sent after the defined AUX. Alarm Delay.

Circuit Breaker Alarm

•

Temperature for Circuit Breaker Alarm: Set circuit breaker alarm temperature.

CO2 Sensor Alarm

•

CO2 High Level: Set the maximum allowed CO2 level above which an alarm is sent. The
alarm ceases when the CO2 drops below this level. If the user acknowledges the alarm, the
alarm messages temporarily cease (for the reminder time).

Humidity Sensor Alarm

•

Humidity Alarm Enabled: Mark this parameter as Yes to enable the Humidity High Level alarm
and the Humidity Sensor Fail alarm.

reoccurs, the alarm relay signals again (after any appropriate delay).

o

Restores normal operation after an emergency pressure or feed overrun incident. If the

controller experiences a high-pressure alarm for too long, it enters emergency pressure
operation by opening all known air sources. Curtains open to preset amounts as set in
Control | Static Pressure. If you select SIREN ONLY, the alarm relay returns to the no
alarm condition, but the emergency pressure status continues.

o

Restores normal operation after a feed overrun situation that calls for turning off the

feeding system. If the feed monitor senses the cross auger runs too long, it trips a feed
overrun alarm and optionally turns off the feed system. If you select SIREN ONLY, the
alarm relay returns to the no alarm condition, but the feed overrun status continues.

The average and the number of weights are the usual definition. The Standard Deviation

is the usual biased estimator (see a suitable textbook on statistical measurements). The
Uniformity is the industry standard 10% uniformity (number of birds per 100 within 10%
of the average weight), and the Coefficient of Variation or C.V. is the normalized
standard deviation (standard deviation divided by average times 100 %.)

9.1 Temperature Calibration

The AC-2000 3G temperature sensors are typically accurate to approximately 0.5º F within the range of
temperatures for poultry production. Calibrate them in this menu by adding/subtracting a constant
correction factor to each sensor. Adjust the sensor of your choice with the left/right arrow keys.

Calibrating against infrared or in air temperature sensors generally results in less accuracy than the basic
sensors have without calibration.

CAUTION Only calibrate the sensors if you have reason to believe that they are producing

inaccurate results.

To calibrate the sensor:

1. Obtain an accurate reference sensors and a pail of water at the approximate temperature

desired.

2. Stir the reference sensor together with the AC-2000 3G sensor vigorously in the bucket of water.

Keep hands off the sensor itself, so that it responds accurately to the water temperature. Stirring is
necessary to preclude stratification within the bucket of water.

CAUTION: The Static Pressure sensor is factory calibrated. Only calibrate the sensor if you have
reason to believe that they are producing inaccurate results.

NOTE:

Run AC-2000 3G for a few hours so that the temperature in the box becomes stable and only
then calibrate.

CAUTION

DO NOT blow the air into the hose to see of the pressure changes! The sensor is sensitive

and blowing air can cause irreparable damage.

12.1.1 G

ROUNDING

•

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.

12.1.2 F

ILTERING

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. Refer to the inverter
documentation.

12.1.3 C

HECKING 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.

12.1.4 F

REQUENCY 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

•

3. Place the controller at least five meters from the inverter.

12.2 Mounting the Unit

1. Install the AC-2000 3G in a dry well lighted area, preferably in an annex to the main poultry
house.

2. Mount it using the three holes provided; one in each of the left and right lower corners,
accessible from the front under the terminal strip cover, and one top center in the back. The top
center hole is a keyhole variety.

3. Install the screw for this hole first to about 0.1 inches of the wall surface. Then hang the control
on this screw. Install the other two screws to fasten the AC-2000 3G.

•

Always connect temperature and sensor shields to earth ground. However, 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 AC-2000 controls.

•

Avoid mixing high voltage wiring with sensor and low voltage wiring.

•

Keep the AC-2000 as far as possible from heavy contactor boxes and other sources of
electrical interference.

Refer to Appendix D: Electrical Grounding for Controllers, page 113, for information on grounding the
unit.
