PROBABLE CAUSE
CORRECTIVE ACTION
208
“Channel” Application Rate
Error (liquid)
A fully open valve is indicated but the target APR
cannot be achieved.
1.
Check to see if the liquid tanks are low, shutoff
valves are partially closed, bypass valves are
open too far, or an obstruction is in the liquid tank
outlet.
2.
Check filters between the liquid tank and
suction side of the liquid pump for blockage.
3.
Check for plugged nozzles or nozzles that are
too small to supply sufficient gallons per minute.
4.
If using a electric liquid pump, check that the
nozzle pressure (spray bar pressure) does not
exceed 40 psi. Some electric pumps have an
internal pressure switch to shut pump off high
back pressure conditions.
5.
Ensure a correct K-FACTOR is programmed.
Compare it against the number stamped on the
flowmeter body or recorded on the Calibration
Data Record Sheet. If original settings are not
available, run a liquid calibration.
6.
Observe the PWM SAT under the Liquid
Configuration screen. Compare against original
setting. If not available, run a system response on
the liquid channel.
250 Prewet Channel Disabled Prewet is not linked to a granular channel.
The system cannot run as configured.
1.
Setup a granular channel to use as a reference
for the prewet application.
2.
Or change the prewet channel type.
300 Invalid Gate Height Sensor
Configuration
The calibration points of the gate height are
incorrect. Most likely, the values do not follow an
increasing or decreasing only pattern.
1.
Check calibration numbers and re-run
calibration.
2.
or accept default values and continue
calibration.
301
Invalid Gate Height Open
Calibration
The open calibration point is near zero. A zero full
open position is not valid.
1.
Check calibration numbers and re-run
calibration.
2.
or accept default values and continue
calibration.
302 Invalid Temperature
Calibration
Temperature calibration did not complete. 1. Verify temperature sensor adapter is
connected and the temperature sensor is
disconnected. With adapter connected and
sensor unplugged, the signal should toggle
between 0.7V and 2.7V.
400
GPS Signal Low Poor GPS signal
1.
Verify GPS is enabled at the F10 screen.
2.
GPS signal may be blocked. Move to a clear
area.
3.
Check that receiver connection is secure.
401
Data Memory Near Full Memory for storing operation data is running low. 1. Export data to a USB memory device.
402
Data Log Memory Full Memory for operation is full and no additional data
can be saved.
1. Export data to a USB memory device.
403 Invalid Task Data A task controller device error may occur on systems
with previous software versions when loading new
software.
1.
Acknowledge alarm and follow onscreen
instructions
2.
Insert a USB memory device.
3.
Export files.
500 Gate High Gate is above the open or highest calibrated point. 1. Check sensor and calibrations.
501 Gate Low Gate is below the closed or lowest calibrated point. 1. Check sensor and calibrations.
502
Bed Height Too High Bed is above the alarm value. 1. Lower bed or check sensor.
503
Down Pressure Too High Down pressure has exceeded the alarm threshold. 1. Reduce down pressure or check sensor.
504 TankPressureLow Tank level has dropped below alarm level.
1.
Fill Tank.
2.
Adjust alarm level setting.
3.
Check sensor.
505 Air Temp Below Alarm Value
1
Temperature has dropped below alarm threshold.
1.
Adjust alarm setting.
2.
Check sensor.
506 Air Temp Below Alarm Value
2
Temperature has dropped below alarm threshold.
1.
Adjust alarm setting.
2.
Check sensor.
507 Air Temp Below Alarm Value
3
Temperature has dropped below alarm threshold.
1.
Adjust alarm setting.
2.
Check sensor.
