Technical Instructions

The  gure bellow show the parameters involved on a  ow failure situation:

This manual is for technical support and it is not recommended change the parameters presented below without a technical person present, assisting the user to do that. If it is not done properly those change can generate an unexpected behavior from the system.

Do not change the con guration of the sensor unless you are certain about what to change and how to change (increase or decrease the value). Once the parameter is changed the technical support should stay with the farmer during the use for at least 1 day, to check if everything is ok.

Sistem’s basic parameters

The  ow sensor has 3 basic parameters:

The TYPE of the  ow: Seed or fertilizer  ow.

The SENSITIVITY, which is related to the intensity of the  ow through the sensor (quantity per hectare and the air speed). Higher the value of the sensitivity a higher intensity of the  ow is needed (more quantity per hectare and/or a higher air speed).

The TIME, which is related to the period of time without  ow that the sensor will wait before sending a no  ow signal to the monitor. The higher the TIME, the higher will be this period.

The monitor has 4 basic parameters:

The MANEUVER DELAY, which is related with the time that the monitors wait to send a failure alarm or enter in a maneuver state.

The NUMBER OF SENSORS TO ENTER IN A MANEUVER STATE, which is related with the number

of the sensors that need to send a failure massage to the monitor until it detects a maneuver situation. This parameter is used only when there are more than 12 rows addressed to the monitor

The PERCENT OF SENSORS TO ENTER IN A MANEUVER STATE, which is related with a percentage of sensor that should send a failure message to the monitor so it can identify a maneuver situation. This parameter is used when less than 12 rows is addressed to the monitor.

The PERCENT OF SENSORS TO EXIT A MANEUVER STAT E , which is related with a percentage of sensor that should send a  ow message to the monitor so it can detect that it is not a maneuver situation anymore.

Tweaking your system

Sensor’s parameters

The default parameter from the system are: 0

SENSITIVITY = 400 TIME = 9

If the system is accusing a “no ow” when there is a ow going through the sensor you can change the sensitivity of the system to a lower value. If in this case you increase the sensitivity you are actually generating more problem to your system.

If you want an alarm as soon as the ow goes down you can increase the sensitivity value, in that case a less intense ow will generate an alarm from the sensor.

The time can be change when a faster alarm is needed, so if the goal is having a faster alarm you can set a lower value in the sensor.

In order to avoid any kind of false alarms, the TIME should be increased and the SENSITIVITY should be decreased. If the SENSITIVITY is set too low it is possible that the residual ow (the ow when the meters are turned off but the air ow is on) stays above this level, so the sensors will take longer to send the “no ow” signal when the meter stops.

TIP:

• The system works for many fertilizer prescription, but the most testing to dene the parameters was done using a 140 lbs./ha @5mph ( 3,5 in between rows) . If your system is operating at these values or higher check other possibilities before changing the sensor parameters.

• If the system is working with a small or low prescription rate range you may need to change the sensitivity parameter.

• If only one sensor or a small number of sensors are presenting problems check if there is any obstruction in the tubes or meters before changing the parameters.

Monitor’s parameter

The default parameter from the system are:

MANEUVER DELAY: 5 NUMBER OF SENSORS TO ENTER IN A MANEUVER

STAT E : 8 sending no ow (when more than 12 rows are

communicating and listed in the monitor – check using function F1)

PERCENT OF SENSORS TO ENTER IN A MANEUVER STAT E : 75% sending no ow (when less than 12 rows

are communicating and listed in the monitor – check using function F1)

ATTENTION:

• Any change in these parameters, even when small, can generate or increase the false alarm if done wrong. Be sure that the concept for each parameter is clear before changing any of this conguration.

PERCENT OF SENSORS TO EXIT A MANEUVER STATE: 50% sending ow The rst information to be clear is that the system works using just one logic to enter in a maneuver state. The monitor does not use both parameter (number of sensor to enter in a maneuver state OR percent of sensors to enter in a maneuver state). Which one is used depends on how many sensors are present to the monitor.

TECHNICAL INSTRUCTIONS | Visum Monitor | | J.Assy Agricultural | TECHNICAL INSTRUCTIONS

It is important to highlight that the monitor work with the number of the sensor that is communicating, if some sensor loses the communication for some reason the total number of sensors is not the number of row installed. To check all the sensors state use F1 function.

row 3 and 7

All the situations presented below are unusual situation and it is just to clarify some specic points. Normally all the sensor sends the messages almost all at the same time and those scenarios are not easy to happen in eld.

A) IF THE SYSTEM HAS MAXIMUM 12 ROWS:

To better explain we will use a number of 8 rows, but all the explanation can be used for a number until 12.

With this condition (maximum of 12 rows the system will use a logic involving 75% of the sensors to detect a maneuver situation. .

If the monitor identies 8 sensor rows presents (communicating) it will go to a maneuver state when 6 sensors (75% of the sensors) send a “no ow” message. In that case when the rst send a “no ow” message it will wait until 5 seconds (maneuver delay) for the second “no ow” message and that will go on until 6 sensors send a “no ow” message.

SCENARIO 1A

S3 send a “no ow” message. Maneuver delay starts to count. After 3 seconds that the maneuver delay started S7 send a “no ow” message. Maneuver delay is reseted and starts over.

SCENARIO 2A

S3 send a “no ow” message. Maneuver delay starts to count. After 3 seconds that the maneuver delay started S7 send a “no ow” message. Maneuver delay is reseted and starts over. After 2 seconds S6 and S4 send a “no ow” message. Maneuver delay is reset e starts over.

After 1 second S1 and S2 send a “no ow” message. That instant the monitor enters in a maneuver state and stay in that state until at least 4 sensors (50% of the sensors) send a “ow” message.

The maneuver delay is also used to exit the maneuver state and report possible failure remaining. So when 4 sensors (50% of the sensors) send a “ow” message the monitor will wait 5 seconds (maneuver delay) before reporting a ow failure.

After 5 seconds any other message was received: Monitor show a failure alert for row 3 and 7.

SCENARIO 1B

The system is maneuver state. S5, S4, S8 and S6 send a “ow” message. The maneuver delay starts count. After 3 seconds S3 send a “ow” message. The maneuver delay starts over. After 2 seconds S7 and S1 send a “ow” message. The maneuver delay starts over. After 5 seconds there is no “ow” message from sensor S2, so the monitor send a alarm informing ow failure on row 2.

B) IF THE SYSTEM HAS MORE THAN 12 ROWS:

To better explain we will use a number of 16 rows, but all the explanation can be used for a number higher than

12. With this condition (more than 12 rows) the system will use a logic involving 8 sensors to detect a maneuver situation. If the monitor identies 16 sensor rows presents (communicating) – or any number higher than 12- it will go to a maneuver state when 8 sensors (number of sensors to enter in maneuver) send a “no ow” message. In that case when the rst send a “no ow” message it will wait until 5 seconds (maneuver delay) for the second “no ow” message and that will go on until 8 sensors send a “no ow” message.

S3, S6, S12 send a “no ow” message. Maneuver delay starts to count. After 3 seconds that the maneuver delay started S7 and S1 send a “no ow” message. Maneuver delay is reseted and starts over. After 5 seconds any other message was received: Monitor show a failure alert for row 1, 3, 6, 7 and 12.

After 2 seconds S5 and S14 send a “no ow” message. Maneuver delay is reseted and starts over. After 1 second S10 and S16 send a “no ow” message. That instant the monitor enters in a maneuver state and stay in that state until at least 8 sensors (50% of the sensors) send a “ow” message.

The maneuver delay is also used to exit the maneuver state and report possible failure remaining. So when 8 sensors (50% of the sensors) send a “ow” message the monitor will wait 5 seconds (maneuver delay) before reporting a ow failure.

SCENARIO 3A

TIP: Depending the actual time of maneuver, when the maneuver fast or takes a short period of time, the monitor does not have time to indicate the maneuver state. This situation not represent a problem with the monitoring system. The change of any of the parameters can easily generate unusual behaviors from the system and any change should be done carefully.

The system is maneuver state. S1, S4, S15 and S16 send a “ow” message. The maneuver delay starts count. After 3 seconds S3, S11, S9 and S13 send a “ow” message The maneuver delay starts over. After 2 seconds S2, S5, S6, S8, S10 and S14 send a “ow” message. The maneuver delay starts over After 5 seconds there is no “ow” message from sensor S2, so the monitor send an alarm informing ow failure on row 7 and 12.

If the user wants avoid a maneuver situation when a section is turned off the number of sensor to enter in maneuver state or the percent of sensor to enter in maneuver state can be increased but notice that it can take more time to detect a maneuver situation.

If the maneuver delay is increased it will take a longer time to dene the situation as maneuver or send “no ow” alerts.

If the maneuver delay in decreased it will recognize a maneuver situation faster but increases the risk of sending many alerts before entering in a maneuver state.

Advanced Functions description

The Monitor has 5 advanced functions that should be accessed only by a technical specialist or service technician or by the user when strictly following specic technical instructions.

In order to access the technical menu, hold both buttons and for ve seconds. The letters tC will appear in the display, followed by the advanced function A1. Press until you reach the desired function, then press to conrm.

The function A1 congures sensor parameters for one particular sensor and the function A2 does it for all sensor at once.

TECHNICAL INSTRUCTIONS | Visum Monitor | | J.Assy Agricultural | TECHNICAL INSTRUCTIONS

It is important to mention that the monitor con gures the sensors when they communicate with the monitor. This communication occurs every 90 seconds or whenever the  ow status changes (e.g., when changing from “OK” to “Failure” or vice versa). So, remote con gurations will  nish quickly if the user forces a status change on the sensors, for example, by stopping the  ow and resuming it after 15 seconds.

A1 | Configure one sensor

Con guration of the parameters of only one sensor.

1. Select function A1,

2. The display will show “Ln” (meaning Line or Row) for 2 seconds.
