Err Message – Error
If a complete loop of Seed Flow sensors is not reported to the Monitor Head, Err followed by the Seed Flow sensor number not reporting to the Monitor Head is displayed; the audible alarm will sound. None of the modes of operation are available and the Err message remains until a complete loop of Seed Flow sensors is established. When an Err message occurs, look for a disconnected Extension cable or Seed Flow sensor at the identified location.

Help Message
If the Monitor Head can not initialize communication with the Seed Flow sensors, HELP is displayed on the Monitor Head. Any part of the AR99 Blockage Monitor could cause a HELP message, but the location of the message is not identified.

Monitor Head
Situation:When turned on, the display remains blank, and no button lights come on.
Solution:
1. Check the power cable is connected correctly
2. Using a voltmeter, check for 12 volts at the red wire, and ground at the black wire.
3. Disconnect the Extension cable from the Monitor Head (the Extension cable routed to the hitch). If the Monitor Head does not turn on, replace the Monitor Head.
4. Check all the Extension cables for damage; crushed, cut, etc. Replace any damaged Extension cables.
5. Make sure the arrows molded onto all the Extension cables are aligned; start at the hitch connection.

Situation:The Monitor Head only displays Err then 1
Solution:
1. Ensure the Extension cable plugs have been connected at the hitch. If the Monitor Head does not detect any Seed Flow sensors, this will occur.
2. Ensure the Y-cable is still connected to the Extension cables connected to the Monitor Head
3. Ensure the Extension cables of the Y-cable are connected to the Seed Flow sensors.
4. Bypass the first Seed Flow sensor by connected the second Seed Flow sensor to the Extension cable from the Y-cable; the Seed Flow sensor count will be one less. Leave the first Seed Flow sensor disconnected. If the message is no longer displayed, replace the first Seed Flow sensor.
5. Connect a Seed Flow sensor directly to the Y-cable. If the message is no longer displayed, replace the Extension cable.
6. Disconnect the Extension cable from the Monitor Head (Extension cable routed to the hitch). Connect the female Extension cable plug of a known “good” Seed Flow sensor to the male Extension cable plug of the Monitor Head; Err then 2 should be displayed. If the Monitor Head still displays Err then 1, replace the Monitor Head.
7. Connect the known “good” Seed Flow sensor to the first Extension cable routed to the hitch; make sure to reconnect the Monitor Head to the Extension cable. If the Monitor Head still displays Err then 1, replace the first Extension cable. Continue this process for each Extension cable up to the Y-cable.
8. Connect a known “good” Seed Flow sensor to the male Extension cable plug of the Y-cable; make sure to reconnect the Y-cable to the Extension cables connected to the Monitor Head. If the Monitor Head still displays Err then 1, replace the Y-cable.
9. Connect the known “good” Seed Flow sensor to the male Extension cable plug of the first Extension routed towards the first Seed Flow sensor; make sure to reconnect the Extension cable to the Y-cable. If the Monitor Head still displays Err then 1, replace the Extension cable. Continue this process for each Extension cable between the Y-cable and the first Seed Flow sensor.

Situation:The Monitor Head always show HI then HELP
Solution:
1. Disconnect the Extension cable from the Monitor Head from the Extension cable routed to the hitch. If HELP is still displayed, replace the Monitor Head.
2. Connect a known “good” Seed Flow sensor to the first Extension cable routed to the hitch; make sure to reconnect the Monitor Head to the Extension cable. If the Monitor Head still displays HELP, replace the first Extension cable. Continue this process for each Extension cable up to the Y-cable.
3. Connect the know “good” Seed Flow sensor to the male Extension cable plug of the Y-cable; make sure to reconnect the Y-cable to the Extension cables connected to the Monitor Head. If the Monitor Head still displays HELP, replace the Y-cable.
4. Connect the know “good” Seed Flow sensor to the male Extension cable plug of the first Extension routed towards the first Seed Flow sensor; make sure to reconnect the Extension cable to the Y-cable. If the Monitor Head still displays HELP, replace the Extension cable. Continue this process for each Extension
between the Y-cable and the first Seed Flow sensor.
5. Bypass all but the first group or tower of Seed Flow sensors. This is done by disconnecting the male Extension cable of the first Seed Flow sensor and the female Extension cable of the last Seed Flow sensor of each group or tower of Seed Flow sensors. Then connect the female Extension cable disconnected from the first Seed Flow sensor to the male Extension cable disconnected from the last Seed Flow sensor. If the Monitor Head no longer displays HELP, reconnect the second group or tower of Seed Flow sensors; disconnect the first group or tower of Seed Flow sensors. Continue this process until the HELP message returns.
6. Bypass the last half of the group or tower of Seed Flow sensors. If the Monitor Head still displays HELP, continue
bypassing half of the halved group of Seed Flow sensors until the Seed Flow sensor causing the HELP message is identified; replace or bypass the Seed Flow sensor.
7. Connect the last half of the group or tower of Seed Flow sensors; disconnect the first half. Continue bypassing half of the halved group of Seed Flow sensors until the Seed Flow sensor causing the HELP message is identified; replace or bypass the Seed Flow sensor.
8. Repeat the Fifth to Seventh step for each group or tower of Seed Flow sensors; there could be more than one Seed Flow sensor.

Situation:When Seed Scan mode is selected the display only shows one of the Seed Flow sensor numbers.
Solution:
1. Make sure the sensitivity dial is not turned fully counter clockwise; this disables Seed Scan mode.
2. If the sensitivity dial is not turned fully counter clockwise, replace or repair the Monitor Head.

Seed Flow Sensors
Situation:Even when sitting in the yard, the Monitor Head never indicates a blockage alarm on any of the Seed Flow sensors.
Solution:
1. Bypass all but the first group or tower of Seed Flow sensors. This is done by disconnecting the male Extension cable of the first Seed Flow sensor and the female Extension cable of the last Seed Flow sensor of each group or tower of Seed Flow sensors. Then connect the female Extension cable disconnected from the first Seed Flow sensor to the male Extension cable disconnected from the last Seed Flow sensor. If the Monitor Head now displays blockage alarms, reconnect the second group or tower of Seed Flow sensors; disconnect the first group or tower of Seed Flow sensors. Continue this process until the Monitor Head no longer displays blockage alarms.
2. Bypass the last half of the group or tower of Seed Flow sensors. If the Monitor Head still does not display blockage alarms, continue bypassing half of the halved group of Seed Flow sensors until the Seed Flow sensor causing all the Seed Flow sensors to report “seeing” product is identified; replace or bypass the Seed Flow sensor.
3. Connect the last half of the group or tower of Seed Flow sensors; disconnect the first half. Continue bypassing half of the halved group of Seed Flow sensors until the Seed Flow sensor causing all the Seed Flow sensors to report “seeing” product is identified; replace or bypass the Seed Flow sensor.
4. Repeat this process for each group or tower of Seed Flow sensors; there could be more than one Seed Flow sensor.

Situation: When a blockage occurred, the Monitor Head did not display a blockage alarm.
Solution:
1. Using a voltmeter, check for at least 13.5 volts between the red and black Power cable wires; a low voltage could cause this.
2. Ensure all the Seed Flow sensors report a blockage alarm. Replace or bypass any Seed Flow sensors that do not report a blockage alarm.

Situation:Even while seeding, the Monitor Head always displays a blockage alarm for all of the Seed Flow sensors.
Solution:
1. Bypass all but the first group or tower of Seed Flow sensors. This is done by disconnecting the male Extension cable of the first Seed Flow sensor and the female Extension cable of the last Seed Flow sensor of each group or tower of Seed Flow sensors. Then connect the female Extension cable disconnected from the first Seed Flow sensor to the male Extension cable disconnected from the last Seed Flow sensor. While seeding, if the Monitor Head no longer displays blockage alarms, reconnect the second group or tower of Seed Flow sensors; disconnect the first group or tower of Seed Flow sensors. Continue this process until the Monitor Head again displays blockage alarms while seeding.
2. Bypass the last half of the group or tower of Seed Flow sensors. While seeding, if the Monitor Head still displays blockage alarms, continue bypassing half of the halved group of Seed Flow sensors until the Seed Flow sensor causing all the Seed Flow sensors to report a blockage alarm is identified; replace or bypass the Seed Flow sensor.
3. Connect the last half of the group or tower of Seed Flow sensors; disconnect the first half. Continue bypassing half of the halved group of Seed Flow sensors until the Seed Flow sensor causing all the Seed Flow sensors to report a blockage alarm is identified; replace or bypass the Seed Flow sensor.
4. Repeat this process for each group or tower of Seed Flow sensors; there could be more than one Seed Flow sensor.

Situation: The Monitor Head displays a blockage alarm, but the Seed Flow sensor is not blocked.
Solution:
1. Confirm the indicated Seed Flow sensor location by unplugging the Seed Flow sensor. The error message displayed on the Monitor Head should be within one number of the indicated Seed Flow sensor. If the location is correct, replace or bypass the “blind” Seed Flow sensor.
2. Locate the proper Seed Flow sensor; opposite side of the machine, tower, etc.
3. Remove the blockage.

Situation:The Monitor Head always displays Err then a number
Solution:
1. Make note of the identified number. Ensure the Extension cables in the indicated Seed Flow sensor location are connected correctly.
2. Visually inspect the Extension cables in the indicated Seed Flow sensor location for damage; a pinch, cut, etc. Replace or bypass any damaged pieces.
3. Bypass the indicated Seed Flow sensor number. This is done by unplugging the Seed Flow sensor, and plugging the cables of the Seed Flow sensor before and after together; the Seed Flow sensor count will be one less. If normal operations begins, replace the bypassed Seed Flow sensor.
4. If the message is still displayed, bypass the Seed Flow sensor before the indicated Seed Flow sensor number. If
normal operation begins, replace the Seed Flow sensor.
5. If an Extension cable connects the two Seed Flow sensors, swap the Extension cable. If normal operation begins,
replace the Extension cable.

Bin & Proximity Sensor
Situation:The air cart tank went empty, but Seed Scan mode never alarmed.
Solution:
1. Check for or HELP messages in Seed Scan mode. If an Err or HELP message occurs the Bin or Proximity sensors
will not report to the Monitor Head.
2. Ensure the product has not built-up between the Bin sensor “eyes”.
3. Ensure the Bin or Proximity sensor is connected to the Junction Box correctly.
4. Replace the Bin or Proximity sensor.

Situation:The air cart tank is full, but the Bin sensor is always in alarm.
Solution:
1. Ensure the product has not bridged over the Bin sensor “eyes”.
2. Ensure the sensitivity dial of the Proximity sensor is not set too high; decrease if necessary.
3. Ensure the Bin or Proximity sensor is connected to the Junction Box correctly.
4. If a Shaft sensor is connected to the same Junction Box channel, make sure the metering shaft is turning.
5. Replace the Bin or Proximity sensor.

Fan Sensor
Situation:When Fan mode is selected no RPM is ever displayed.
Solution:
1. Press the Seed Scan button. The Fan sensor will not report RPM if an Err or HELP message occurs.
2. Ensure the Fan sensor is connected to the Junction Box correctly.
3. Ensure the Fan sensor is in-line with the metal target.
4. Ensure the Fan sensor is within the required distance from the target; an 1/8 of an inch.
5. Disconnect the Fan sensor from the cable connected to the Junction Box. Using an ohmmeter, check for a resistance of 500 to 5000 ohms between the red and black wires of the Fan sensor. If not, replace the Fan sensor.
6. Inside the Junction Box, disconnect the cable from the Fan sensor. Quickly and repeatedly make and break a connection between the green and black wires; a RPM should be displayed in Fan mode. If not, replace the Junction Box. Otherwise, replace the cable connecting the Fan sensor to the Junction Box.

Situation:The air seeder fan RPM displayed in Fan mode is not correct or unstable.
Solution:
1. Ensure the Fan sensor is in-line with the target.
2. Ensure the Fan sensor is within the required distance from the target; an 1/8 of an inch.
3. Swap the red and black Fan sensor wires.
4. Check the cable connecting the Fan sensor to the Junction Box for intermittance. Disconnect the Fan sensor.
Connect the two wires of the cable connecting the Fan sensor to the Junction Box together. Begin shaking, flexing and stressing the cable connecting the Fan sensor to the Junction Box. If a RPM is displayed in Fan mode, replace the cable connecting the Fan sensor to the Junction Box.

Shaft Sensor
Situation:A shaft stopped turning, but Seed Scan mode did not alarm
Solution:
1. Check for an Err or HELP messages in Seed Scan mode. If an Err or HELP message occurs the Shaft sensors will not report RPM.
2. Ensure the Shaft sensor is connected to the Junction Box correctly.

Situation:The Shaft sensor number in Seed Scan mode is always in alarm even when the metering shaft is turning.
Solution:
1. Slowly turn the sensitivity dial counter clockwise; if the sensitivity dial is set to high, this could occur.
2. Ensure the Shaft sensor is connected to the Junction Box correctly.
3. If a Bin or Proximity sensor is connected to the same Junction Box channel, make sure the air tank is not empty.
4. Replace the Shaft sensor
