Navigation Buttons
These buttons allow you to scroll up and down in the screens that have more than 8 lines. Continuously
pressing the up or down arrow button increases the scrolling speed. When you are in the Edit Mode the left
and right arrow keys move the cursor to editable (changeable) positions. The cursor highlights the areas that
can be changed.
Edit Buttons
When the button labeled EDIT is pressed and you are looking at a screen that has editable fields, the cursor
appears. With the Navigation Buttons, you can move the cursor to the parameter on the screen that you want
to edit. By pressing the “+” or “–” buttons, the numerical values are changed. If you are changing text (i.e.
“yes” or “no”), the "+" and "–" keys scroll through the possible text choices. Pressing the EDIT button a
second time exits the edit mode.
Fast Edit
While editing a number on the screen, you will notice that the digit you are changing is underlined. For
example: (72.0). If you wish you can move to different digits of the number in order to change the number
more rapidly. To do this See Figure 3 below. Fast Edit is very useful when making large changes to numbers.
Security
To provide for security in setting your Controls, there is a security feature that appears when you press the
Edit button. The Control automatically asks for an access code at that time, The access code is a four digit
number that you have selected while setting up the Control and is explained under the “Changing the Access
Code”section of this manual. 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 3 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 Current Weight screen.

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.
SJB Box (Scale Junction Box)
The SJB Box translates information from the Loadcells to the LCI. Each SJB can be connected to a maximum
of 6 Loadcells. A maximum of two SJB’s can be connected to the LCI.
Screen 1: Current Weight
Screen 1 (Figure 9) shows a brief summary of the current conditions of the house. There are no editable values
in this screen; it is for viewing only.
1. Silo Bin 1- The current weight in Bin #1.
2. Silo Bin 2- The current weight in Bin #2.
3. Check Alarms- This will appear (flashing) if the LCI detects an alarm condition. This will continue
to appear until the condition is corrected and noticed.
4. Date and Time- Current date and time.
Screen 2: Alarms
At the top of Screen 2, all current alarm conditions will be
listed. If there are no alarm conditions, the status of the alarm
will show at the top of the screen. The three possible statuses
are ENABLED, DISABLED, and TEST. The status field is
editable. See the "Alarms" section of this manual for more
alarm information.
1. For this example, a power failure has occurred and
recovered; this information is at the top of the screen
and will remain there until the alarm is NOTICED.
2. The time, date and type of alarm of the most recent
10 alarms are listed in the lower part of the screen.

3.Time and Date- Set the current time and date.
4.Total Silo Bins- The total number of silo bins connected to the control.
5.Calibrate Silo Bin 1(2)- This where the loadcells are calibrated. After connecting the LCI, SJB and
Loadcells, make sure there is no feed in the bin. Answer YES to the Zero line to zero calibrate the
loadcells. The Acutal = line should now read 0. Next place a known weight on the bin. Enter this
weight on the weight line. When the proper weight has been entered answer YES on the Weight line
to calibrate the span of the loadcells. Remove the known weight and the number in the Actual
Weight line should return to 0.
NOTE: The units of measurement are chosen at calibration. If the number entered in the weight line is in
pounds, than the LCI will weigh in pounds. If the number entered in the weight line is in Kilograms, then the
scale will weigh in Kilograms.
6.Access Code- There is always an access code. From the factory the value is set at "1111". The 1111 is
a special code that tells the control not to ask for an access code when the edit button is pressed. If it is
desired, the access code can be changed to a 4 digit number. To change the access code answer YES to
change access code at the bottom of screen 3. Then enter the desired 4 numbers buy pressing the sub-
ject buttons on the front of the control. If an access code can not be recalled please contact your Chore-
Time distributor or service representative.

Load Cell Indicator Initial Setup Procedure
MT2316A 9
Once the LCI has been properly installed, the LCI is ready to be setup.
1. Go to the Setup Screen (Screen 3) by pushing button 3.
2. Setup the LCI Control number, time, and date. Key in the LCI how many bins are connected totthe LCI.
3. Follow the calibration prodedure to calibrate the Loadcells of each Bin.
When all of the data has been entered into the Setup Screen (Screen 3), the LCI is now ready to display the
weight in the Bin.
Initial Setup Procedure

Control Operation Overview Load Cell Indicator
10 MT2316A
In Screen 1 (Button 1) the weight of each Bin is displayed. The unit of measure displayed depends upon how
the LCI was calibrated in the Setup Screen.
Alarms
At the top of screen 2 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 2 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 2 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 2 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 2 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 2 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.
Alarm History
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
SJB 1 (or 2) IO Net Error
This alarm will occur when the LCI can not communicate with one of the SJB boxes. Check to make sure that
the SJB boxes are connected properly to LCI, that the address DIP switches are set properly and that there is
power to the SJB. See the wiring diagram on page 14 for information on connecting the SJB to the LCI.
Service Alarms
Listed below are additional alarm codes that relate to the internal operation of the LCI. Contact the nearest
Chore-Time Distributor or CTB service personnel if one of these alarms occur.
Mounting the Control
The LCI Control requires a minimum mounting area of
approximately 10" x 14" [55.9 cm x 55.9 cm] This
dimension is allowing extra room for the Control Door
to open. (See Figure 12). The box should be mounted
level on a solid backing using the mounting holes
