•
If the monitor is still trying to communicate with each
module, the top line will show “TEST.”
•
If the monitor can communicate with the number of
sensors set for each module, the top line will show
“TST OK”.
•
If the monitor cannot communicate with a blockage
module, the module number will be displayed, but is
sensor digits will be blanked out.
•
If the monitor cannot communicate with the module
after several attempts, an alarm will sound. Silence
the alarm by pressing the ACK button. The mes-
sage “BLKERR” and the number of the problem
module will flash briefly every few seconds. Check
that the modules and monitors are wired correctly.
Check that each module has the correct address-
switch setting. Refer to the installation instructions
included with the option package.
Calibrate Mode
Before using the blockage monitors, you must calibrate
the sensors for your seed and seeding rate. During the cal-
ibration mode, the blockage modules measure and record
the seed-flow rate for each one-inch seed hose. This
stored value is used during the operate mode to determine
when hoses are blocked. You must calibrate the system
whenever you set a new seeding rate or change your seed
type.
To calibrate the blockage monitors:
1. Set the displayed function to “FLOW” by pressing the
up or down button.
2. Press and hold the ACK button. The monitor will give
four short beeps then one long beep. Release the but-
ton. The monitor will now display “TEST” or “TST OK”
on the top readout.
3. Lower drill, pull forward and beginning seeding. When
the monitor detects motion, it will double beep and dis-
play “CAL” on the upper line. The system is now in the
calibrate mode.
4. During calibration, the monitor display will cycle
through module and run numbers as flow information
is recorded. Module and run numbers displayed are
for hoses that have not yet calibrated.
5. Calibration will be complete after about two or three
minutes of continuous seeding. Any hoses that have
not calibrated in this time probably are blocked. Stop
the drill and clear any blockages, then proceed with
seeding to finish calibration.
NOTE: Stopping the drill to clear blocked runs will not up-
set the calibration process. When motion stops, the moni-
tor suspends calibration until 30 seconds after motion
resumes.
6. When all runs on the module have calibrated, the run
number will be replaced with two dashes. For exam-
ple, “3.--” indicates that all runs on module three are
calibrated. When all runs on all modules have calibrat-
ed, “CAL OK” will be displayed on the top line and the
monitor will beep rapidly several times.
7. Press ACK to end the calibration mode and restore
normal monitor operation, including flow monitoring.
NOTE: If you wish to prematurely exit to the calibration
mode, hold the ACK button for five beeps. Any sensors
that have not yet calibrated will generate flow errors.
Operate Mode
During normal operation, the blockage modules will con-
tinuously monitor seed hoses for plugging–even when the
monitor displays a different function such as fan speed.
When the monitor detects a blockage problem, an audible
alarm will sound and the monitor will display “FLOW” on
the upper line. To correct a flow alarm:
1. Silence the alarm by pressing the ACK button. The tri-
angle indicator will continue to blink as long as the
problem persists.
2. If some other function was displayed when the flow
alarm went off, use the up or down button to move to
the flow function. The display will indicate one of two
alarm conditions.
Blocked Seed Hose. If the monitor detects a seed-
hose blockage, the monitor will alarm and display the
location of the block.
For systems equipped with Pin sensors the readout
will display the module and run number. For example,
if the display reads “M4 R9,” seed hose nine on mod-
ule four is blocked.
For systems equipped with Optical sensors the read-
out will display the row number only. For example, if
the display reads “Blk 25,” seed hose 25 on the imple-
ment is blocked.
Communication Error. If the monitor detects a com-
munication breakdown between the monitor and any
blockage module, the monitor will display “BLCKERR”
and the number of the problem module.
3. Check the indicated hose or module for plugging or
improper connections. If the monitor detects problems
on multiple modules or hoses, it will display each in or-
der as you press ACK. When all blockages are clear,
the monitor will display “OPEN.”
