The
FAN
function will be required to
set the appropriate blower speed. An alarm
has been set to alert the operator if the fan
is too fast.
DO NOT OPERATE THE FAN
ABOVE 4500 RPM.
Check fan speed
when seeding has commenced. Fan
speeds will often be slightly higher when
actually conveying material.
The
Shaft 1
,
Shaft 2 and Shaft 3
(if
fitted)
functions will show the speed of the
metershaft that is actually metering the
seed and fertilizer. Alarms have been
preset to warn against slow or high shaft
speeds. If after calibrating your seeder you
forget to engage the front bin drive sprocket
the alarm will sound and be displayed as
‘SHAFT 1 STOPPED’
. This alarm will
repeat until the problem has been rectified.
The
‘PRESSURE’
function will enable
the operator to check the system’s air
pressure at any time. The pressure
indicates the conveying performance of the
blower. This may not be very useful when
first using the air seeder but over time can
help in checking your distribution system
and even indicate if your have a blockage
or major air leak.
Once familiar with the Air Seeder’s
operating
pressure
for
a
particular
application rate, you may wish to set the
low and high-pressure alarm to warn
against a cap or hose coming loose or a
blockage while conveying material.
Clutch Switch
A separate clutch switch is supplied
that can be mounted independently from
the monitors. It also requires its own power
separate from the monitor. Do not use the
lighter monitor power harness when
connecting.
If for some reason the monitors have to
be removed, it is still possible to run the
clutch switch independently.
Fig. G2 Clutch Switch (single shown).
Preset Values
When you first switch the monitor on,
check the setting. The monitor should
display “Gason A/S GT 2/3”. If the display
is different it will be necessary to correct
this. Refer to the section titled ‘Calibration’
default set-up in the Farmscan 2200
Surveillance monitor instructions manual.
Refer to the Farmscan operator’s
manual if more information is required.
If you need to recalibrate the monitor
refer to the monitor’s ‘Operator’s Manual’
for details. The following Gason default
values have been used to preset your
monitor.

NOTE: 2 Bin Air Seeders do not require the
‘S3’ Shaft Alarms. It is suggested that the
operator changes both the S3 Low and S3 high
alarm value to zero to prevent activation.
