5. Calibration pulses/kg value is different to
previous
calibrations
with
similar
product.
Check bulk density of product is similar
to the previous material.
Check material flows freely and is not
wet or binding to bin or meterwheels.
Check sprocket ratio and meterbox
setup is the same as previous samples.
Check that the proximity sensor is
operating correctly.
6. Monitor will not come off Hold.
Fan has not been engaged or is running
below the low fan alarm.
7. Monitor comes off hold but metering
system does not operate.
Check monitor display for a ground
speed feedback. If no speed is
displayed check sensor operation and
distance to target on the drive wheel.
Check the fuse attached to the main
power loom at the battery. Replace with
similar sized blade fuse (20amp).
8. Reasons why a particular bin does not
start.
Bin is switched off.
Bin is not calibrated.
Some earlier model VRT seeders (pre
2001) are fitted with a blade fuse to
protect each electric over hydraulic
controller.
Check
and
replace
if
necessary with similar sized blade fuse
(3 amp). Fuses are located along loom
on the left-hand side of the seeder,
close to the hydraulic manifolds.
Refer to your service agent for further
instructions.
9. A particular bin will not stop or rotates
slowly when the monitor is placed on
hold.
Check that the manual override valve is
turned off. Refer to the manual override
section for more information.
Remove all electrical power to the
seeder’s pod by disconnecting the main
breakaway plugs (switch off monitor
first). If the metering system stops the
problem is electrical. If the Hydraulic
motor continues to turn the problem is
related to a hydraulic issue. At this stage
it would be advisable to contact your
local dealer for more information.
10. Fan speed will not display or displays
erratically.
Check fan speed sensor is connected.
Rotate sensor in housing and check
sensor has 3mm gap to magnet in back
face of impeller. Finally, replace sensor.
