”

section on

Page 39

. Once you have inserted the correct code, the

Control allows you to make changes. If five minutes pass since your last change, the access code has to be re-entered.

Subject Buttons

On the front of the Control are 12 subject keys. As each subject button is pressed, the light beside that button turns on and the subject that is described beside the button appears on the screen. If no other buttons are pressed for 5 minutes, the

Control automatically returns to the

Indication Lights and Auto/Manual Switches

Each Relay Output has its own three position Switch that allows the user to manually control each Relay. The Relays and their corresponding Switches are located in a seperate adjoining box. Decals are supplied to label each Switch according to the output function that is assigned to that Switch. The Switches can be placed in three positions — “on”, “off”, or “auto”. The “auto” position is for normal automatic operation. Changing a Switch to “on” or “off” overrides "auto" operations. When a switch that is assigned is placed in a position other than

“auto”, a message will appear in the

Current Conditions

screen advising you to

“Check Switches”.

The light above each Switch indicates that the Switch’s Relay is activated.

Model 16 Control Glossary of Terms

Glossary of Terms

Anticipation

When the Control is cycling Minimum Ventilation Timer Fans with the Minimum

Ventilation Timer, the Control will open the Inlets to the correct position for Static

Pressure Control before the Fans are turned on. The Control teaches itself how much adjustment was required during the previous cycle, and uses that amount of

“anticipation” for the next cycle. If any of the Minimum Ventilation Timer Fans are on due to temperature, or any other Fans are on, the “anticipation” does not occur.

Bend Point (

BP

)

The Bend Points (BPs) are simply the points on the curve that define the curve. For the Set Temperature and Minimum Ventilation Timer curves, the curve values are gradually changed between bend points. The bend point values are the exact values at midnight beginning the day # of each bend point. The curve takes over when you turn the curve “on” and the day number is equal to or greater than the day number assigned to BP #1.

Cool Pad Output

The COOL PAD output is a special function for controlling evaporative cooling that allows you to modulate the addition of water to the cooling pad in such a way that the usual large temperature swings associated with a cooling pad are avoided.

Curve

A “curve” is a listing of up to 10 points in time (bend points) that defines how you want a parameter to automatically vary as the animals age.

Curve Value

The Control will list what the current value(s) the curve would be, if the current day number is greater than the day # of bend point #1, and the curve is “on”, and there is no “offset” to the curve.

Day Number

The intention is that the day # is the age of the animals whose environment is being controlled. Day # 0 does not exist. Negative days (down to – 7) are allowed.

Changing the day # in any screen that shows the day number, will change the day # in all the other screens that show the day #.

Event

This term applies to the time clock outputs. An “event” is an “on at” time combined with an “off at” time. Each clock output can have up to 8 events.

MT1732A

Glossary of Terms Model 16 Control

Mode Sensor(s)

The concept of Mode Sensor(s) is essential to the understanding what makes the

Control change from one mode to another. The Mode Sensor(s), of a currently operating mode, determines when the Control will leave that mode. As an example, while in the Power Mode, the Power Mode Sensor(s) determines when it’s too hot to stay in the Power Mode (i.e. above the tunnel “on” temperature). Because of this, it converts to the Tunnel Mode (assuming there is no Natural Mode) at the tunnel “on” temperature. It comes back to the Power Mode from the Tunnel Mode, when the

Tunnel Mode Sensor(s) say it’s too cold to stay in the Tunnel Mode (i.e. below the tunnel “off” temperature).

Natural Mode

Natural Mode requires the house to be equipped with Curtains in the side walls that are powered by Drive Units (Curtain Machines). The Control converts to this mode of operation when the temperature(s) inside the house raise to a level that the Fans of the Power Mode can’t keep the temperature(s) under control. While in the Natural

Mode of operation, the Curtains are opened or closed, as required, to control the temperature(s). This mode of operation generally happens during moderate weather.

18

Mt1701-Naturalmode 11/01

Figure 34. Natural Mode

Noticing an Alarm

“Noticing” an alarm is a very important part of using the alarm system. With button presses, you can tell the Control that you have “seen” the alarm message. The simplest way to do this is to first press the alarm button to read the alarm message(s) at the top of the alarm screen. Each additional press of the alarm button (while you’re still looking at the alarm screen) “notices” the alarm(s), one at a time.

MT1732A

Model 16 Control Glossary of Terms

Offset

The term “offset” applies to the Set Temperature and Minimum Ventilation Timer curves only. If you manually adjust either the Set Temperature or the Minimum

Ventilation Timer settings, while the curve is on, you create an “offset” to that curve relative to it’s “curve value”. The “curve value” is not changed. (see the “curve value” definition above.) The curve value is shown as a convenience so that you know what you have to change it back to in order to get back on the actual curve’s table listing. While an “offset” is in effect, the parameter of the curve is still modified versus time. However, the actual parameter value is the “curve value” modified by the “offset”.

Power Mode

The building is closed up except for Inlets (usually Baffle Doors) which are powered open and close in order to control the static pressure level. In some cases Gravity

Inlets are used where the static pressure is not controlled directly. The only ventilation provided is due to Fans mounted in the end or side walls. This mode of operation generally happens when the outside temperatures are somewhat lower than the set temperature.

MT1732A

Mt1701-Powermode 11/01

Figure 35. Power Mode

Program

A “program” is a complete set up of all the screens of a Control. In screen 11, five different “programs” can be saved and later activated. This can be very convenient when it is desired to change the set up at different points during the grow out or barn cycle, or times of the year.

Set Temperature

The set temperature is another very important, basic, concept. All temperatures are referenced to the set temperature. When the set temperature is adjusted either manually, or because the set temperature curve is on, all other temperature settings move up or down by the same amount. For instance, even though you program an actual temperature for each Fan to come on and off, when you change the set temperature, those Fan’s on and off temperatures are adjusted by the same amount you changed the set temperature.

19

Glossary of Terms Model 16 Control

Static Pressure

Static pressure refers to the pressure difference that exists between the inside of the house and the outside of the house. This pressure difference is the result of Fans in the walls running. The air that they exhaust enters the house through various types of air Inlet openings. In the Power Mode the typical powered Baffle Inlets is where the vast majority of the air enters. In the Tunnel Mode, the Tunnel Inlet at the end of the house is where the air enters. The pressure drop, due to the resistance to the air flowing through the Inlets, is the reason a static pressure difference exists. If the

Inlets are all the same size, the same amount of air will enter through each Inlet. In the Natural Mode of operation, the outside wind is the source of the air, with no

Exhausting Fans running. In general there is no static pressure during the Natural

Mode due to the huge area of the open Side Wall Curtains.

When the incoming air is cooler than the inside air, it will tend to drop down onto the birds before it is warmed up. Adequate static pressure brings the air into the house high and fast so that it heats up before it can fall.

Tunnel Mode

This mode of operation requires a group of large (usually 48 in.) Fans at one end of the house with a large air Inlet area at the opposite end of the house. The Control converts to this mode of operation from the Power or Natural Mode (if used), when the temperature(s) while in those modes get too high. The typical 5 or 6 mph. breeze, which can be created by the Tunnel Fans running, produces a wind chill effect that is significant. This mode of operation happens during warm to hot weather.

20

Mt1701-Tunnelmode 11/01

Figure 36. Tunnel Mode

Wind Delay

The static pressure has to be out of the Control limits continuously for the “wind delay” amount of time before the Inlets are adjusted. If a Fan or Fans has turned on or off within the last 10 seconds, the wind delay does not happen and the Inlets respond as soon as the static pressure leaves the Control limits.

Screen 2, (Figure 9)

is mostly an editable screen where several important parameters are programed.

1. The “set temperature” is a very important parameter. All other temperatures are keyed to the set temperature. When the set temperature is changed, all other temperature settings are also changed by the same amount to maintain the same temperature differences relative to the set temperature.

2. The Temp Curve and Min Vent Curve “on” indications are not editable. They only indicate that the curve(s) are “on” and the curve’s value. If a curve is not “on”, there is no indication in this area. The values shown in the parentheses are the current curve’s values. If the actual values are different, the difference represents the

“offset”. Editing the actual values to be the same as the values shown between the parentheses will erase the offset(s). An "offset" is caused if you change a value when its curve is on.

3. The Minimum Ventilation Timer can be attached to Exh Fan, Tun Fan, and Stir

Fan outputs in screen 3. The “on” and “off” times for this Timer are set up here in screen 2. The Timer turns the Fan on or off when the temperature is below the Fan’s

"on" temperature. A Timer can only be attached to a Tun Fan output if the "on" temperature setting of the Tunnel Fan is set lower than the “on” temperature of the

Tunnel Mode. Allowable “on” times for this Timer are 0 or greater than 30 seconds

(1 through 29 seconds is not allowed). Allowable “off” times for this Timer are 0 or greater than 60 seconds (1 through 59 seconds is not allowed). The “on” and “off” times cannot both be set at 0.

Timers 1 and 2 can be attached to Cool, Tun Fan, Exh Fan, and Stir Fan outputs in screen 3. The “on” and “off” times for these Timers are set in this screen. These

Timers behave like the minimum ventilation Timer except when they are attached to a Cool output. When attached to a Cool output, the timer has no effect until the Cool output is “on” due to it’s temperature settings. At that point the Cool output goes on and off with the Timer. The Cool output never comes on continuously when Timer 1 or Timer 2 is attached to it. There are no limitations to the “on” and “off” settings for

Timer 1 and Timer 2 except that the “on” time and “off” time cannot both be set at 0.

The “stir on” Timer is different than the other Timers. It can only be attached to Stir

Fan outputs in screen 3. The “stir on” time value is set in this screen. The purpose of this feature is to allow you to cause a Stir Fan output to run for the “stir on” amount of time immediately following the end of the Minimum Ventilation Timer’s “on” time. Because of this, the Stir Fan is synchronized with the minimum ventilation

Timer. The "stir on"setting can be any value up to the “off” time of the minimum ventilation Timer. The Stir Fan outputs will come on full when the temperature rises to the "on" temperature value set in screen 3.

Figure 10. Outputs-Temperatures Screen

Screen 3, (Figure 10)

is a very important screen. It is the screen that determines at what temperatures Outputs operate.

An important tip regarding the use of this screen is to get in the habit of asking yourself which Temperature Sensor (or combination of Temperature Sensors) is assigned to the various outputs shown on this screen. For instance, in the above example, where Exh Fans 3 and 4 are set to come “on” and “off” at the same temperatures, they may not go “on” and “off” together if they are assigned to different Sensors in screen 12.

1.

This column lists the “on” temperatures of the outputs listed in column 3. For outputs above the set temperature, the output goes from “off” to “on” with rising temperature. For the Heat Zone outputs, below the set temperature, they go from

“off” to “on” with falling temperature. After changing any temperatures in the

“on” column, the screen will re-sort itself according to the “on” temperatures the next time you select this screen.

2.

This column lists the “off” temperatures of the outputs listed in column 3. All

Heat Zone output’s “off” temperatures (as the temperature rises) are fixed to be

0.5 degrees above their “on” temperatures. The “on-off differentials’’ of all other outputs are adjustable. For Fan outputs the “off” temperatures are either the value of the next lower Fan’s “on” temperature or the value you specify in the OFF column for that output. The default “off” temperature for the lowest temperature Fan output is the set temperature if an "off" temperature is not entered. The minimum “on-off differential” allowed for Fan outputs is 0.5 degrees F.

3.

The output names listed in column 3 are a result of what is programed into screen 12.

23

Overview of Screens

Model 16 Control

4.

In column 4 you attach a Timer to those outputs you want to be affected by a

Timer. See the screen 2 description regarding how the various Timers behave and which outputs can have which Timers attached to them.

5.

The amount of time since midnight of each day that each of the Heat Zone outputs have been “on”. These values are zeroed at midnight of each day. Time is measured in hours and minutes.

6.

This is the temperature of the Power Mode Sensor(s) where the Control will change from the Power Mode to the Natural Mode.

7.

The “on” and “off” temperatures of the Tunnel Mode are entered here. The Control will convert to the Tunnel Mode when the Natural (if used) or Power Mode

Sensor(s) raises to the Tunnel “on” temperature. The Control will convert back to the Natural (if used) or Power Mode when the Tunnel Mode Sensor(s) reaches the “off” temperature. The minimum allowed difference between the

Tunnel “on” and “off” temperature is 3 degrees F.

8.

The Cool Pad Range’s “on” and “off” temperatures have a very different meaning from the “on” and “off” temperatures of the other outputs. The “on” temperature is the high limit of the desired range while the "off” temperature is the low limit of the desired range. See the

"Cool Pad Function"

section of this Manual for more details regarding the COOL PAD function.

9.

For both the Natural and Tunnel Modes it is possible to ALLOW or NOT

ALLOW the mode to occur in these fields of screen 3. Do not use the YES/NO questions in screen12 to temporarily disable either mode.

10. If the sensor(s) assigned to Variable Speed 1 are at or below the temperature set here, the Variable speed 1 fans will run at the minimum speed set in Screen 9. If the Min Vent timer is assigned to this output the Variable speed 1 fans will cycle on the timer at the minimum speed if the sensor(s) are at or below this temperature.

11. If the temperature here is set to the same temperature as the Variable Speed 1 temperature then the Variable Speed 2 (if used) fans will run at the minimum speed set in Screen 9 when the sensor(s) assigned to Variable Speed 2 are at or below this temperature.

12. If the temperature set here is different from the Variable Speed 1 temperature

(at least 1.5 degrees F) then the Variable Speed 2 fans will shut off when the sensor(s) assigned to Variable Speed 2 are at or below this temperature. The

Variable Speed 1 fans will reach maximum speed (100 percent) .5 degrees F below this temperature.

The temperature set here defines at what temperature Variable Speed 1 and Variable

Speed 2 reach maximum speed. When Variable Speed 1 and Variable Speed 2 (If used) are set to the same temperature then the variable speed fans will reach maximum speed when the sensor(s) assigned to each output reach .5 degrees F below the Max Var Spd Temperature. The Max Var Spd temperature must be at least 1.5 degrees F above the Variable Speed 1 and Variable Speed 2 temperatures.

If Variable Speed 1 and Variable Speed 2 are set to different temperatures then Max

Var Spd defines at what temperature the Variable Speed 2 fans reach maximum speed only. Variable Speed 2 fans will reach maximum speed when the sensor(s) assigned to Variable Speed 2 reach .5 degrees F below the Max Var Spd temperature.

The temperature at which Variable Speed 1 reaches maximum speed is defined by

Variable Speed 2 temperature.

Note: No other fans’ on and off temperatures may be placed in between the set temperature and the Max Var Spd temperature. When editing the temperatures of the

Variable Speed outputs, it is recommended that the Max Var Spd temperature be edited first and then the Variable Speed temperature(s).

Figure 12. Light Clock Screen

Screens 4 and 5, (Figures 11, and 12)

are identical in all ways except for the words

“feed” and “light”. The use of these different words is for convenience only. An event is defined as an “on plus off" time combination for the Relay(s) assigned to each clock. The “on at” and “off at” times refer to the contacts of the output Relay(s). “On” means the contacts are closed and “Off” means the contacts are open. 12:00a is midnight.

1. The first group of events, at the top of the screen, indicates the current settings of the clock. If the curve is ON, and today’s day # is equal or greater than

BP1’s (Bend Point one’s) day #, you cannot change the current clock area of the screen. (For more information about Bend Point see

Bend Point

in the Glossary of

Terms section of this Manual) If you want to change the clock’s schedule temporarily, turn OFF the curve and adjust the current clock events to the temporary settings. Turning the curve back ON will return the clock to the curve’s settings.

2. The “on at” and “off at” times cannot span across midnight. The example shown above, “on at 8:00p” and “off at 5:00a “is not allowed.

3. In order to accomplish “on at 8:00p” and “off at 5:00a“, you need to program 2 events as shown above. This results in the output Relay being “on” from 8:00p to

5:00a. without interruption.

4. The software will not allow you to overlap events. The example shown above will not be allowed. If you do this you are telling the Control you want the output Relay to be on twice during the overlapped time. A Relay can only be “on” or “off”. If you overlap the events you have made a mistake in your settings.

In screen 12 you can also set up one or two spare clocks. Spare Clock 1 shows in screen 4, and Spare Clock 2 shows in screen 5. The Spare Time Clocks do not have the curving capability.

The high and low temperatures of the Control Sensor(s) (with a time of day stamp), the water usage, and the total heat zone run time for each of the heat zones are listed. In that the Control Sensor(s) may be different for the different possible modes, it is quite possible for the max temp to be the temperature of a different Sensor or average of a group of Sensors than the min. temp. For instance, the maximum max temperature would normally happen in the afternoon when the Control is in Tunnel Mode. The min. temperature would usually happen in the early morning when the Control is in

Power Mode

Figure 16. Min. Ventilation Timer Curve Screen

Screens 8 and 9 (If Variable Speed is not being used)

Screens 8 and 9, (Figures 15, and 16)

are very similar in layout and how they behave. There are several terms that need to be defined in order to understand the description of these two screens,

1. A “curve” is a listing of up to 10 points in time (bend points) that defines how you want a parameter to automatically vary as the animals grow. You make the Control do that by turning the curve “on”.

2. This indicates the current value(s) of the specified curve.

3. The Bend Points (BPs) are points on the curve that define the curve. For the set temperature and Minimum Ventilation Timer curves, the curve values are adjusted between the Bend Points. The bend point values are the exact values at midnight of the day # of each Bend Point. The curve takes over when you turn the curve “on” and the day number is equal to or greater than the day number assigned to BP #1.

4. The intention is that the day # is age of the animals. Negative days (down to – 7) are allowed if it is desired to preheat the house, for example, prior to the arrival of the animals. The day # of a BP can also be negative, if desired. Changing the day # in any screen that shows the day number, will change the day # in all the other screens that show the day #.

Screen 10, (Figure 18)

indicates the current static pressure plus provides the fields that can be edited to set the Static Pressure Control limits and the wind delay. The open and close Inlet Relays respond as required to keep the static pressure within the control limits while in the Power Mode and the open and close Tunnel Curtain Relays do the same to control the static pressure during the Tunnel Mode. If it is not desired to control the static pressure during the Tunnel Mode, the high control limit in the

Tunnel Mode must be edited to be .00.

Static Pressure Control limits

The Static Pressure Control limits are the values of static pressure the Control attempts to maintain by using the powered Inlets, the Tunnel Curtain, or both. A second level of Power Mode static pressure can be chosen in screen 12. The temperature at which the second static pressure takes over is entered in screen 3.

The Temperature Sensor(s) ,(Inside Only ), that measure that temperature is defined in screen 12.

Static Pressure Alarm limits

The static pressure levels, above and below the control limits, that will cause an alarm when the static pressure stays continuously outside these limits for 1 minute and a Fan or Fans is running. The static pressure alarm limits are programed in screen 7.

Static Pressure Safety limits

When the static pressure stays above 0.20 for a continuous minute, the Tunnel

Curtain (if in Power Mode) and the Inlets (if in Tunnel Mode) will open until the static pressure reduces below 0.20. Once the problem is fixed and the static pressure reduces below 0.18, the Control returns to normal operation. This situation will always result in a High Pressure Alarm.

Wind delay

The wind delay is the amount of time the static pressure has to be continuously outside of the control limits before the appropriate open or close Relay will be energized to bring the static pressure back within the control limits. The wind delay is bypassed if a Fan or Fans turning on or off is what causes the static pressure to move outside the Static Pressure Control limits.

MT1732A

29

Overview of Screens Model 16 Control

Static Pressure Control w/ Tunnel Curtain during Power Mode

If, in the Power Mode, there is inadequate inlet area to keep the static pressure within the high control limits, the Tunnel Curtain will open to give additional air inlet area. The Inlets are given continuous open signals as the Tunnel Curtain takes over the responsibility of controlling the static pressure. The static pressure has to be above the high Static Pressure Control limit continuously for one minute with 3 or more Fans running for this to happen. Responsibility for Static

Pressure Control is passed back to the Inlets as soon as there are fewer than 3

Fans running or the Tunnel Curtain cannot bring the static pressure back into the control range (while closing) from the low side. The static pressure has to be below the low Static Pressure Control limit continuously for one minute for this to happen.

At each midnight, the setup of the Control is saved which can also be re-activated at any time during the following day. This can be helpful if a mistake is made while changing the setup and you wish to “undo” the changes.

2.

The programs listed in the parentheses after “Select program” shows which program numbers have been saved making them available to activate.

The “Current program” indicates the program that is currently active. This field changes back to a (-) as soon as you change any parameter that affects the operation of the Control. This lets you know that there has been a modification to the most recently activated setup.

4.

A program is saved by first carefully setting up all the screens of the Control to be what you desire that program to be. Editing the number to be the program number you want to give that set up, and then answering YES to the last question on the screen is how you save that setup to be the program number you have chosen.

the Setup Screen is where you tell the Control what it is controlling. You tell the Control which Relays you want to control based on which

Sensors (if the output is controlled by temperature). You also specify which modes of operation the various Relays are allowed to operate in. Many settings that you specify in this screen will determine what appears in several of the other screens.

You also define which Sensors will determine when the Control changes to a different mode of operation. Towards the bottom of the screen, you have the ability to calibrate the Sensors. The Sensors initial tolerance is such that calibration is not generally required. The Curtain calibration procedure (for Natural Mode operation only) is required in that it is telling the Control where the full open and close positions are.

Initial Setup Procedure Model 16 Control

Initial Setup Procedure

Once the Control has been properly installed and all outputs have been tested manually, the Control is now ready to be set up. The following section should be used only as guide to setting up the Control. This section will provide a general overview and procedures for programming and setting up the Control.

Before beginning to set up the Control, make sure that all of the Toggle Switches in the Relay Box have been placed in the manual “off” position

(See Figure 21).

This will insure that no outputs will accidentally turn on during setup. Also make sure that the Output Stickers have been placed over the correct Toggle Switch. This will aid in programming the Control.

Special Note:

When first powering up and setting up the Control, the light next to the alarms button (button #7) may flash. Ignore this flashing light until the Control is fully set up.

Model 16 Control Initial Setup Procedure

Calibrations

The calibration section of the setup screen allows the user to re-calibrate inputs if necessary. This section should not need to be used at initial installation and start-up of the Control unless natural ventilation is used. If natural ventilation is being used then the Potentiometers will need to be calibrated at this time. If it is felt that one of the inputs needs to be re-calibrated

Perform the Following Steps...

Temperature Sensors

To re-calibrate the Temperature Sensors, first obtain a digital thermometer that has a readout of at least .1

°

.

Do not use a temperature gun

. A temperature gun takes object temperatures, not air temperatures. Place the digital thermometer next to the Temperature Sensor that is being re-calibrated. Take the reading from the digital thermometer and enter that number under the temperature column,

(Item 1 Figure 28),

of the Sensor being calibrated. The Correction column,

(Item 2, Figure 28),

is used only for service information and to return the Control to the factory settings. The settings should be reset to factory whenever a re-calibrated Temperature Sensor is replaced. To return to factory settings change the number under the correction column by one digit. This will cause the correction to automatically zero out and return to factory setting.

To re-calibrate the static pressure Sensor first obtain a manometer or other static pressure measuring device. Then disconnect both hoses from the Static Pressure

Sensor. Go to the static pressure portion of the setup screen

Look at the Pressure reading on the Zero Level line

(Item 1, Figure 29)

. If the reading is not zero then change the zero level pressure to read zero. The zero level has now been calibrated.

To calibrate the high level, first make sure that the Manometer has been installed in the house and reconnect the hoses to the Static Pressure Sensor. Then open the

Inlets slightly and turn on enough Fans to create a static pressure of at least 0.15 inches of w.c. at the Manometer. Then compare the Manometer reading to the reading on the High Level line of the Chore-Tronics Control

(Item 2, Figure 29)

.

If the readings do not match, edit the pressure reading on the High Level line to match the reading of the Manometer. As with the Temperature Sensors, the

Correction column,

(Item 3, Figure 29)

, of the static pressure calibration is used for service, and to return the Control to factory settings only. This completes the re-calibration of the static pressure Sensor.

Relative Humidity Sensor

To recalibrate the Relative Humidity Sensor first obtain a sling psychrometer or other humidity-measuring device. Operate the psychrometer in the same area that the Relative Humidity Sensor is installed. Take the reading on the psychrometer and compare it to the reading in the Relative Humidity Sensor

Calibration section of the setup screen.

Caution!

This procedure involves using the manual toggle switches for the Main Curtains open and close outputs. Always place the open or close switch in its manual “on” position by itself. Never place both the open and close switches in the manual “on” position at the same time. This will cause the Curtain Machine to try to open and close at the same time and could cause motor or Relay failure.

Figure 32. Changing the Access Code

The Control comes set from the factory with no access code required to make changes. If an access code is desires first change the “NO” to a “YES” at the change access code line of setup screen. The Control will then ask for the old password. From the factory the old password is 1111. This is entered by pushing the number 1 (Current Conditions) button 4 times. You can then enter a new access code by using the subject buttons as the numbers that you want to use. For example, an access code of 1952 would be entered by pressing in succession the

Current Conditions button (button #1), the Minimum Ventilation Timer Curve button (button #9), the Light Clock button (button #5), and the set temp/min vent button (button #2). The Control will then ask you to confirm your access code.

Once an access code has been entered, the Control will ask for that code any time the Control has set idle, (no buttons pressed), for more than 5 minutes, and the edit button is pushed. If an access code is no longer desired, change the access code back to the factory setting of 1111, and no code will be required to make changes.

Model 16 Control Control Operation Overview

Control Operation Overview

Standard Mode Functionality

Power Mode

All Curtain(s) are given a continuous close signal. Inlets are controlled by static pressure (if used). All outputs that are allowed to operate in Power Mode turn on and off per screen 3 trying to satisfy their Sensors assigned in screen 12.

Natural Mode

Each Curtain is closed or opened independently by its own control sensor(s).

Each movement of the Curtain is 1.2 inches per degree F. relative to the set temperature. There is a pause of 2 minutes between each open or close movement. If the Curtain’s Control Sensor(s) return to within + or - 1.5 degrees

F. of the set temperature, the open or close Relays are turned off. This range of

+ or – 1.5 degrees F. is termed the “temperature control range” of natural operation. If the temperature of the Curtain’s Control Sensor gets to be more than

8 degrees F. above the set temperature, that Curtain’s open Relay will be energized the amount of time to move the Curtain 24 inches or until the temperature control range is reached. If the temperature of the Curtain’s Control

Sensor gets to be more than 8 degrees F. below the set temperature, that Curtain’s close Relay will be energized until the first opening position is reached (causing the transition to Power Mode) or the temperature’s control range is reached.

All outputs that are allowed to operate in Natural Mode turn on and off per screen

3 trying to satisfy their Sensors assigned in screen 12.

Tunnel Mode

The Main Curtains, if used, are given continuous close outputs. The Tunnel

Curtain is given continuous open outputs (or adjusted to control static pressure).

The outputs that are allowed to operate in Tunnel Mode turn on and off per screen

3 trying to satisfy their Sensors assigned in screen 12.

MT1732A

Control Operation Overview Model 16 Control

Mode Transitions

There are six possible mode transitions:

1. Power to Natural

2. Power to Tunnel

3. Natural to Power

4. Natural to Tunnel

5. Tunnel to Natural

6. Tunnel to Power

The sequences of events that happen for each transition are very different and deal with the various considerations that must be dealt with in order to safely get from one mode to another. These events are described below.

Power to Natural

In the Power Mode, the Main and Tunnel Curtains are completely closed. When the Power Mode Sensor reaches the temperature in screen 3 that you have defined to go to Natural, the Main and Tunnel Curtains will open for the amount of time required to open each Curtain the distance that you have indicated in screen 12 as the desired first opening movement. The Control calculates this amount of time based on the speed you have specified in screen 12 for each of the different Curtain’s speeds.

If the temperature drops 0.6 degrees F. within the first 2 minutes after the Curtain reaches the desired first opening, the Control will immediately close all the

Curtains, returning to the Power Mode. This represents the “fast temperature drop test”. If the temperature does not drop this fast, the Control will proceed to normal Natural Mode operation, opening or closing depending on whether the temperature is above or below the set temperature by an amount greater than 1.5 degrees F. The distance the Control moves each of the Curtains each time is based on the temperature difference between each Curtain’s controlling

Sensor(s) and the set temperature (1.2 inches per degree F. temperature difference with the set temperature when they move). There is a 2 minute pause between each Curtain’s movement. Once the temperature returns to being within

1.5 degrees of the set temperature for an individual Curtain, that Curtain will stop moving until the temperature for that Curtain once again gets more than 1.5 degrees away from the set temperature.

42

MT1732A

Model 16 Control Control Operation Overview

Power to Tunnel

This transition begins when Natural is not allowed in screen 3 (or natural ventilation is not even a part of the set up in screen 12) and the Power Mode

Sensor reaches the temperature to go to the Tunnel Mode. The transition proceeds as follows:

1.) The Tunnel Curtain starts to open.

2.) Thirty seconds before the Tunnel Curtain reaches the half open position, the

Inlets go continuously closed.

3.) The Fans that are running immediately prior to the transition continue to run until the Tunnel Curtain gets to the half open position. At that point, the Fans that are called for to be on in tunnel take over. It is quite possible that some, if not all, of these two sets of Fans are the same Fans, depending on what is programed in screens 3 and 12.

4.) Thirty seconds after reaching the half open position, the Tunnel Curtain begins to control static pressure. This happens if the upper control limit of the tunnel Static Pressure Control limits in screen 9 is set to a value other than .00.

If the upper limit is set at .00, the Tunnel Curtain does not pause at the half open position and goes continuously open.

The amount of time necessary to get to the half open position is calculated by the

Control using the Tunnel Curtain speed and full open distance that you specify in screen 12.

Natural to Power

The natural to power transition occurs when the Main Curtain returns to it’s “first opening” position, while going closed. If there are two Main Curtains, (Main1 and Main2), the transition occurs as soon as both Curtains are at or past their first opening positions in the process of going closed. It must be cooler than 1.5 degrees below set temperature for the Curtains(s) to move in the close direction, but temperature by itself does not cause the transition from Natural to Power

Mode. The Fans that are called for to be on in the Power Mode are delayed from coming on until the Main Curtain(s) have enough time to get closed. The Tunnel

Curtain is given a continuous close signal during the entire Natural to Power transition. Heat zone outputs are disabled for an additional 2 minutes to minimize fuel waste while the temperatures stabilize after the transition is over.

Natural To Tunnel

The Natural to Tunnel transition occurs when the Natural Mode Sensor reaches the temperature in screen 3 for Tunnel to be “on”. The Main Curtain(s) are given a continuous close signal as the Tunnel Curtain is given an open signal that lasts enough time to reach the half open position if the Tunnel Curtain is set up to control static pressure, or else continuously open if the Tunnel Curtain is not set up to control static pressure. While the Main Curtains are going closed and they reach the desired first opening position , the Tunnel Fans turn on that are called for to be on. The Main Curtains are given a continuous close signal as the Control continues in the Tunnel Mode.

MT1732A

43

Control Operation Overview

44

Model 16 Control

Tunnel to Natural

The Tunnel to Natural transition occurs when the Tunnel Mode Sensor drops to the temperature in screen 3 for tunnel to be “off”. The Tunnel Fans that are running turn off and the Main Curtains are given continuous open signals for the amount of time required to completely open the Main Curtains. At that point the

Control proceeds with the normal Natural Mode operation, opening and closing the Main and Tunnel Curtains depending on how far each Curtain’s assigned

Sensor(s) are different than the set temperature.

Tunnel to Power

The Tunnel to Power Mode transition occurs when the Tunnel Mode Sensor drops to the temperature in screen 3 for Tunnel to be “off” and Natural Mode is either “not allowed” in screen 3 or not even a part of the installation in screen 12.

The Fans that are called for to be on due to being in the Power Mode turn on immediately as the Fans that have been on because of Tunnel Mode turn off.

Similar to the Power to Tunnel transition, several or even all of the Fans that were on in Tunnel, just prior to the transition, may stay on after the full transition to

Power depending on the way the Control is set up. The Side-wall Air Inlets are given a full open signal during the transition. The Sidewall Inlets begin to control static pressure once the transition is completed.

Minimum # of Tunnel Fans On

In screen 12 the “Minimum number of Tunnel Fans on” is set up. This puts a limit on the temperature rise from one end of the house to the other while in Tunnel Mode. As the animals grow this "Minimum number of Fans" value should normally be increased. This parameter has no effect on how many Fans are on in the Power Mode just prior to the transition to Tunnel. The temperature settings set up in screen 3 determine the number of Fans that operate while still in the Power Mode before making the transition from Power to Tunnel.

The actual “TUN FAN” outputs that make up this min. group of Fans are those "Tun

Fans" that have the lowest temp. settings in screen 3. If more than one “TUN FAN” output is set at the same temperature in screen 3, the Control will arbitrarily pick enough of those TUN FANS to add up to the minimum # specified in screen 12.

Cool Pad Function

The COOL PAD output is very different from a COOL output. It is not intended that the COOL PAD output and the COOL output would be used together, even though they could be. They are both there to give the choice of which to use. The COOL

PAD’S Relay operation is designed to begin the cooling caused by the cooling pad by first adding 5 seconds of water to the pad every 5 minutes. If the temperature is still within the “Cool Pad Range” after 4 doses of 5 seconds of water, the amount of water added to the pad every 5 minutes is neither increased nor decreased. If the temperature at the temperature check point is above or below the temperature limits of the “Cool Pad Range”, the amount of water "on" time each 5 minutes is increased or decreased 5 seconds. The temperature is only checked every 20 minutes.

On a very hot day it would be possible for the water to be running continuously and the temperature to be in the “Cool Pad Range”. A more moderate day might result in the water running a very small amount of time in order to keep the temperature within the “Cool Pad Range”. Similarly, on a low humidity day the amount of water required to keep the temperature within the “Cool Pad Range” would be less than for a high humidity day. The Control will adjust the water as required to keep the temperature in the “Cool Pad Range”. The parameters that determine what the COOL PAD output does are set up in screen 12.

MT1732A

Model 16 Control Control Operation Overview

In screen 12,

(Figure 32)

the parameters that determine exactly what the Relay does are listed. Unless you see poor control of temperatures during pad operation, Chore-

Time strongly recommends that you use the initially supplied settings (except for the two parameters described below). We also request that you contact the CTB service department to discuss your situation before you try different values.

Measure the number of seconds it takes for water to start coming out of the holes in the pad system’s top distribution pipe after you turn the Toggle Switch “on” to the

COOL PAD Relay. This should be entered as the “Water pre-fill time”,

(Item 1,

Figure 32)

and is likely to be different for different pad system manufacturers. This amount of time is added to the water run time each repetition in that the top distribution pipe drains out between each on-off cycle.

Measure the number of seconds it takes for water to start dripping out the bottom of a dry pad after you turn the toggle switch “on” to the COOL PAD Relay. This should be entered as the “Time to wet dry pad”,

(Item 2, Figure 33)

. This will be less than the amount of time to make the pad completely soaked. When the actual water on time reaches this "Time to wet dry pad" value, the next step is to run the water continuously, assuming the temperature is above the Cool Pad Range at the next temperature check point. Once the temperature decreases back below the Cool Pad

Range, the actual water on time will return to the "Time to wet dry pad" value again.

From there the water on time changes in the normal way, with 5 second changes every 20 minutes, depending on the temperatures at the temperature check points.

The “actual water on time”,

(Item 3, Figure 33)

, is for information only. Showing the value makes it possible to create a graph of it’s variations if you have the PC connection (C-central).

The “Flush cool pad”,

(Item 4, Figure 33)

,is a feature that allows you to run the water continuously at a time of day each day for the duration you specify. This will guarantee that at least once a day the pad will be flushed to keep it as clean as possible and help lengthen the Pad life. Leaving dashes for the settings disables this feature.

Flushing the Pad in the night will have the advantage of causing very little unwanted temperature drop.

Control Operation Overview Model 16 Control

Curves

The clocks, Set Temperature and Minimum Ventilation Timer can be curved, if desired. This means that the settings for these parameters can be automatically changed by the Control. The “bend points” (BP) of the curves are the day numbers

(age of birds, for instance) combined with the desired values of the settings at those day numbers. In the case of the Clock Curves, the settings stay the same from one bend point to the next bend point. For the set point and minimum ventilation Timer curves, the Control adjusts the settings gradually between the bendpoints.

When the curves are turned “on”, the Control will refer to the curve values and automatically adjust the settings to the curve value beginning at midnight of BP1’s day number. Negative day numbers are allowed (Max= - 7). (Day number 0 does not exist). Day 1 would normally be the day the birds are placed.

Refer also to the glossary of terms for this subject.

Timers

There are four different Timers available for different purposes:

Minimum Ventilation Timer

This is explained in the "

Overview of Screens: Set Temp./Min. Timer

" section of this Manual.

Timer 1 and Timer 2

These Timers can be attached to COOL, TUN FAN, EXH FAN, and STIR FAN outputs in screen 3. The “on” and “off” times for these Timers are set in screen

2. These Timers behave like the Minimum Ventilation Timer except when they are attached to a COOL output. When attached to a COOL output, the Timer has no effect until the COOL output is also “on” due to it’s temperature settings. At that point, the COOL output goes on and off with the Timer. The COOL output never comes on full when Timer 1 or Timer 2 is attached to it. There are no limitations to the “on” and “off” settings for Timer 1 and Timer 2 except that the

“on” time and “off” time cannot both be set at 0.

Stir on

The “stir on” Timer is different than the other Timers. It can only be attached to

STIR FAN outputs in screen 3. The “stir on” time value is set in screen 2.The purpose of this feature is to allow a STIR FAN output to run for the “stir on” amount of time immediately following the end of the minimum ventilation

Timer’s “on” time. The setting can be any value up to the “off” time of the minimum ventilation Timer. This function is in parallel with the STIR FAN output in the same manner that the minimum ventilation Timer is in parallel with outputs it is attached to. The STIR FAN outputs will come on full when the temperature rises to the value set in screen 3.

Control Operation Overview

Alarms

At the top of screen 7 a current alarm condition(s) will be listed. If there are no alarm conditions, the status of the alarm system will show at the top of the screen.

The three possible statuses are ENABLED, DISABLED, and TEST. The status field can be changed.

Enabled

If the alarm system is ENABLED and one or more alarms arise, there will be alarm message(s) at the top of the screen. After pressing the screen 7 button the first time, the alarm Relay will be changed to the non alarm state for one minute and the alarm-screen will be shown. By pressing the screen 7 button a second time the alarm message will change from ALARM to the status NOTICED. This second button press is the manner that you tell the Control that you are aware of the alarm condition and, in so doing, NOTICE the alarm condition. If there is more than one alarm condition, you NOTICE each additional alarm condition with an additional button press for each additional alarm condition. If you fail to

NOTICE an alarm with the additional button press(s), the alarm Relay will return to the alarm state one minute after the initial screen 7 button press. If the alarm condition is still present when you NOTICE the alarm, the word ALARM to the right of the condition will (for most alarm conditions) change to OFF FOR 24:00.

The time setting is editable. It gives you time to deal with the problem. If you do not fix the problem, the alarm Relay will once again trigger your alarm system at the end of the time period. If the alarm condition has RECOVERED by the time you NOTICE the condition, the alarm message disappears when you NOTICE it and it is added to the alarm history at the bottom of the alarm screen.

Disabled

It is possible, but not recommended, to DISABLE the alarm system of the

Control. One reason for this could be that the house is empty. The light beside the screen 7 button will flash slowly to remind you that the alarm system is disabled, but the alarm Relay will not change to the alarm state. The alarm history shown at the bottom of screen 7 does list that the alarm system was disabled, when, and for how long.

Test

If the user chooses TEST, the alarm Relay will immediately change to the alarm state. This allows testing the alarm system that is external to the Control

(telephone dialer, for instance.) NOTICING the ALARM TEST, as you would a normal alarm, erases the alarm message and returns the alarm Relay to the non alarm state. Also, an ALARM TEST notification will be listed in the alarm history.

Warning

There also is an alarm message status called WARNING. This does not change the state of the alarm Relay, but alerts you that something isn’t right. It needs to be NOTICED in the same way as a “hard” alarm in order to turn off the flashing lights, etc. An example is a failed Sensor.

At the bottom of the alarm screen is a listing of the most recent 10 alarms. The date and time of each alarm is shown. The amount of time elapsed (hh:mm) from the time the alarm occurs until the alarm is noticed and recovers is also show.

Alarm Messages

Sensor Failure #

If a Sensor that is assigned (used) for any purpose gets below 0

°

F or above

120

°

F for 1 minute, a

silent

alarm (WARNING) will be given. The temperature of the backup Sensor defined in screen 12 will be used while the failed Sensor situation exists. If there are multiple, concurrent Sensor failures such that it is impossible for the Control to determine a temperature or temperature average that is needed, a

loud

alarm will be given (the alarm

Relay changes to the alarm state). At the same time, the Relay(s) using the failed Sensors turn off. If Mode Sensors are involved, the current mode will not change as long as the alarm condition exists. When an average of Sensors is involved, all of those Sensors, plus the backup Sensor for each Sensor used in that average, would have to fail in order to result in a hard alarm.

Min / Max Rel Sensor #

The Minimum and Maximum Relative Temperature Alarm limits refer to the set temperature. A +10.0 maximum relative alarm means that one or more of the Sensors that are a part of the current mode’s Control Sensor get to be greater than 10 degrees higher than the set temperature. The alarm message indicates which of the Sensors is outside the limits. Between the parentheses to the right of the Min and Max Relative Alarm limits are the resulting actual temperature limits. They are simply the addition or subtraction of the limit to or from the current set temperature

Pressure Alarm Min / Max

The Static Pressure Alarm limits are only considered by the software when a Fan or Fans is running or would be running if the toggle switch(s) were in the automatic position.

For the Static Pressure Alarm to occur, the static pressure has to be outside of the Alarm Limits for 1 minute of accumulated Fan run time. Any reading within the alarm limits while a Fan or Fans are running resets the accumulated run time to zero. For the case where the only Fans running are cycling with a Timer, it can take more than one cycle of the Timer for the alarm to happen. This is true when the “on” time of the Timer is less than 1 minute. The “off” time of the Timer does not add to the accumulated “on” time.

Pressure Failure

If the pressure measurement gets outside of the Static Pressure range of -.05 to 0.40 continuously for 1 minute, regardless of the Fans on/off status, a static pressure failure alarm will happen. The Inlets will be given continuous open signals if this occurs.

Low Water Pressure

An optional mechanical water pressure switch can be attached to the left 2 terminals of the D2 input to the I/O board in order to detect a low water pressure condition. The switch contacts need to be closed when the pressure is above a safe lower limit. In screen 12 you can program an alarm delay time in order to screen out transient low water pressure conditions. The Low

Pressure Switch alarm is set at the factory to come on at 5 PSI and goes back off when the pressure rises above 10 PSI.

Model 16 Control Control Operation Overview

Program # Activated

Activating a program in screen 11 does not represent a hazard, but it is very helpful to evaluate where you have been in terms of the program(s) used. The alarm history shows activity of program activation. The alarm light will flash, and when you NOTICE the alarm message, it will disappear to the alarm history. The Alarm Relay does not change to the alarm state.

Pot # Not Responding (Natural ventilation only)

This alarm is generated whenever 2 minutes of open or close time does not result in at least 10 counts of change to the pot readout. Changing direction resets the 2 minute Timer. This alarm is also generated if there are 10 or fewer counts to the pot readout during the first opening transition. The 2 minute Timer does not advance and is reset to zero whenever the pot readout is within 10% of either calibration limit.

Pot # Outside Limits (Natural ventilation only)

This alarm is generated whenever the pot readout is more than 10% past the calibration limit at either end.

Listed below are additional alarm codes that relate to the internal operation of the Control. Contact CTB service personnel, if any of these alarms occur.

Limp Modes

A limp mode is an abnormal type of operation that takes place whenever certain conditions occur. The object is to take action to minimize the effect of a Sensor failure. The following four limp modes exist:

Failed Temperature Sensor

A Temperature Sensor is considered to be failed if the reading of the Sensor is less than 0 degrees F. or greater than 120 degrees F.

The Limp Mode is:

The backup Sensor for the failed Sensor is used instead with no alteration to normal function. A quiet alarm is given (the Alarm

Relay does not change states, but the Alarm Light beside button 7 flashes).

If the backup Sensor also fails, and there are no other Sensors assigned to a given output, that output will turn off and the Alarm Relay changes to the alarm state. There very likely will be either high or low temperature alarms as well.

Failed Static Pressure Sensor

A Static Pressure Sensor is considered to be failed if the Sensor indicates that the static pressure is less than -.05 or greater than .40 continuously for 1 minute.

The Limp Mode is:

If the Control is in the Power Mode, the Inlets will be given a continuous open signal and the Tunnel Curtain will be given a continuous close signal. If the Control is in the Tunnel Mode when the Static

Pressure Sensor fails, the Tunnel Curtain is given a continuous open signal, while the inlets are given a continuous close signal.

50

MT1732A

Model 16 Control Control Operation Overview

Pot not responding

This failure mode can only happen in the Natural Mode. It happens when the pot for either the Main1 or Main2 Curtain does not change at least 10 counts during

2 minutes of accumulated open or close signals. The 2 minute time count stops whenever the pot readout gets within 10% of the number of counts of the calibration limits. The time count resets to zero each time the Curtain changes directions. This failure mode also occurs if there are not more than 10 counts of change when the Main Curtain(s) open to it’s first opening position.

The limp mode is:

1. The Main Curtain Relays continue to be energized to go open or closed according to temperature as if there Potentiometers were responding correctly.

2. All outputs that are set up in screen 12 to be allowed to come on in the

Power Mode will now come on in the Natural Mode.

The reason for this is that if, in fact, the Curtain(s) are not moving, the

Curtain could be closed, and it is essential that the exhaust Fans run. If the pot(s) is not responding, the Control can not actually return to the Power

Mode because the transition from Natural to Power Mode is based on the

Potentiometer position.

Pot outside limits

This failure mode is mainly an indication that the pots are not properly calibrated.

The pot readout is outside the range of 10% past the pot limit values. For instance, if the pot limits were 150 and 350, the pot would be outside the limits if the readout was ever less than 135 or more than 385. The limp mode is exactly the same as for “pot not responding”.

Relative Humidity

If a relative humidity Sensor is installed, it can be used simply as a management tool for your awareness. It also can be used to block the COOL and COOL PAD outputs if the relative humidity rises above the limit set in screen 12. If you don’t want the humidity to block the COOL and COOL PAD outputs, simply adjust the limit to

100%.

Access Code

There is always an access code. From the factory the value is set at 1111. The

1111 access code is special, however, in that it won’t ask you for this code except if you want to change the code to something else. If you do choose to use an access code, be sure to write it down in a safe place. The choice to change the access code is at the bottom of screen 12. It must be 4 numbers. The numbers are entered by pressing the buttons on the face of the Control. The screen numbers correspond to the digits you are choosing for your access code. If you have installed an access code and it can not be recalled and has not been recorded, contact Chore-Time for assistance.

Wiring of Outputs

The Outputs for the Chore-Tronics Controls (Fans, Curtain Machines, Brooders, etc.) are wired to one of the Relays on the Relay Module or (RM Board(s))

(See

Figure 36, Item 5).

The RM Board consists of eight 1hp motor load Relays. Each

Relay has single-pole, single-throw normally open contacts. It is strongly recommended that the assignment of outputs to the Relays be done before starting to wire the Control. This will make routing of the electrical wires through the Relay box much easier

(See Figure 47)

.

When testing the Toggle Switches for the Curtain and Inlet Machines, be sure to test them one Switch at a time.

After testing the open switch, place it in the manual "off" position before placing the close switch in the manual "on" position. If you try to put both switches in the manual

"on" at the same time you will send a double signal to the Curtain Machine Motor.

Testing the Back Up Box

To test the Back Up Box, first turn the power off to the Chore-Tronics Control only.

This should cause the Tunnel Curtain to open and the first set of Back Up Fans should activate. If this test is successful, turn the power back on to the Chore-Tronics

Control. Then adjust thermostat number one until it activates. Then adjust the second thermostat until it activates. This should cause the second set of Back Up Fans to activate. After all Back Up Fans are operating, deactivate the first two thermostats.

Than adjust the third thermostat until it activates. This should cause the Back Up

Heaters to activate.

After all of the Outputs and Back Ups have been successfully tested, make sure all manual toggle switches are in the manual "off" position and proceed to the

PROBLEM

Display difficult to read

Display Completely Blank

The control is stuck on a screen other than screen 1 (For example

Screen 4). The control immediately returns to that screen after another subject button is released

One of the Subjects on the KD board will not come up on the screen when the subject button is pushed. The button can not be felt

.

The control says that the pressure in the house is -.10” and will not calibrate to .00”. It will only calibrate to a -.05”.

Equipment and Potentiometer Troubleshooting

POSSIBLE CAUSE

A.) Display adjustment potentiometer on KD board needs to be adjusted.

B.) Back light on display board unplugged or defective.

A.) Flat cable between KD board and Display board is unplugged or defective.

B.) Defective Display board.

C.) Defective KD board.

There is a nut that holds the KD board screwed in too tight and is causing button 4 to be held in constantly.

POSSIBLE SOLU-

TION

A.) Adjust pot until screen can be read (for adjustment procedure see page #).

B.) Check two wire plug on Display board. Replace if defective.

A.) Check flat cable connections.

Replace cable if defective.

B.) Replace Display Board.

C.) Replace KD board.

Open the control and find the nut closest to button 4 and loosen it until the button is disengaged.

All Temperature sensors are Frozen at 32

°

F.

°

F.

There is a nut that holds the KD board that is too loose.

There is a wire connection problem between the static pressure monitor and the IO board. When the static pressure monitor is disconnected from the IO Board the control defaults to a reading of -

.10”.

The I/O Chip is improperly installed.

A.) Connections in temperature sensor, junction box, and/or I/

O Board have become loose and/or corroded.

B.) Defective temperature sensor.

Find the nut closest to the screen causing the problem and tighten it until the button will activate.

Check for wires being switched, broken wires, wires not making a good connection, etc. An easy way to remember the wiring is that the red wire is connected to the positive terminal of both the

IO board and the static pressure monitor.

Chip is either upside down, has a bent pin, or in not pushed completely into the socket. Check out chip and correct.

A.) Check all temperature sensor connections correct any problems.

B.) Replace temperature sensor.

The lights above the manual switches are dimmer when on in the automatic mode than in the manual mode. Also Lights flash bright for a second in automatic mode.

The indicator light is wired directly across the coils of the output relay. When the switch is placed in the manual on position the full 24 volts are placed on the coil, causing the light to glow bright. When the relays are told to come on by the control in automatic the full 24 volts is applied to pull the contacts in and then the voltage is reduced to hold the contacts in. This causes the light to glow dim. When the relays are on in automatic mode, the control puts full voltage across the coils to make sure the relay is still engaged.

Model 16 Control Improving Lightning Surge Suppression

Improving Lightning Surge Suppression

Lightning can be a very destructive and expensive phenomenon. It does not always take a direct “hit” for lightning to cause extensive damage to electrical equipment.

The Chore-Tronics controls do have components that help suppress and/or isolate power surges such as lightning. These components many times will protect the controls from the power surge or at least keep the damage isolated to one board on the control. However, more direct strikes or strikes that hit network wires such as alarm wires to phone dialers or the C-Central network can cause damage to numerous boards in numerous controls. If the farm is located in a lightning prone area or if there is a network of wires connecting all Chore-Tronics controls together (such as C-

Central or an alarm system), then additional lightning protection should be considered. These products are available from Chore-Time. The products available will be discussed later in this section. It should also be noted that a back-up system consisting of mechanical back-up thermostats be installed in the event of a control failure. Chore-Time has a back-up box available (Part Number 40727).

Before obtaining lightning suppression devices, first check the system grounding of each house/room. Every building needs to have its own ground rod and that ground rod must be driven deep enough into the ground that it will have good contact year round. Please check with the local electrician and/or electrical inspector for specific ground rod requirements in your area. In some areas one ground rod may not be sufficient to provided a good ground to earth, in that case an electrician should be consulted to find alternate ways of obtaining a good Earth ground. Again, be sure to check with a qualified electrician for grounding requirements.

Once a good grounding system has been established, if lightning is still a concern, surge suppressors should be considered. It is recommended that there be a suppressor installed at the main distribution panel for the farm (Chore-Time Part Number 47663) and a suppressor installed on the service panel of each house/room (Part Number

47662). If C-Central and/or an alarm system is used then there should be a low voltage suppressor (Part Number 47660) installed at every control and a telephone line suppressor (Part Number 47661) installed at the phone line on the farm.

See

Figures 54 through 57

on the following pages for the wiring diagrams and more information on location and installation of these devices.

Installing these devices does not guarantee that the farm will not be struck by lightning or that equipment will not be damaged from lightning strikes. However, they will greatly increase the amount of protection already there, and thus will reduce the chances of having lightning damage occur.

MT1732A

77

Troubleshooting after a Lightning Strike Model 16 Control

Troubleshooting after a Lightning Strike

On

page 95

there is a flow chart to help trouble shoot a Control that has taken a lightning strike. Keep in mind that the flow chart represents what can happen when lightning strikes a Control. Before using the chart please

see Figures 54-57 below

to become familiar with terms and location of equipment discussed in the chart. If after using the chart the Control still does not function please contact your Chore-Time distributor or Chore-Time Technical Service Department.

If the Control(s) located on the farm are taking multiple hits a year, please see the section following the trouble shooting chart on suggestions for improving lightning suppression on the farm. Look at this section particularly if you have C-Central installed on the farm and/or a telephone dialer system where all controls are connected to one dialer.

NOTE:

If the display at the control is not functional (unreadable or no display), troubleshoot the other boards first because the display may not be bad.

If you think your Control has been subject to a lightning strike check to see if the

Indicator Lights on each Board are either on or Flashing on and off.

(Figure 54)

. If an Indicator Light is not on then that is an indication that that Board has been damaged.
