Check Swath
Note that the swath value was automatically updated
when either the # of Rows or Row Spacing were revised
and saved.
18. Examine the swath (width) value. It should be very
close to the value from the table on page 118. If it
has a small round-off error, you can ignore it, or
manually set the swath value to match the table
value. Use
to select the swath field. Use
to modify. Use ENTER to save.
Row Setup
When setting up a planter configuration, the monitor
automatically sets all row sensors to On
, and clears
any previous settings for Off , Disabled or Flow .
If you are using alternate row spacings (other than all
rows on), Great Plains recommends configuring that
setup as planter configuration 2
or 3 . Use
configuration 1 for all rows on.
Set Ground Speed Constant
Refer to Figure 103
The monitor factory default for speed constant (sensor
pulses per 400 feet) is incorrect for this planter family.
A correct constant is required for accurate monitor
reports of hectares planted and seeds per hectare.
There are two ways to obtain and enter a useful
constant:
• Recommended:
Perform a speed calibration as described in the
DICKEY-john
® 11001-1372 manual. This creates a
number the is accurate for your field conditions and
intended planting speed.
• Alternate:
Enter the suggested default constant manually. This
number is approximate, and is based on factory tests
on fields, and at speeds, that may differ from yours.
Manual Speed Calibration Entry
Refer to Figure 104
1.
Press the GROUND SPEED SETUP key. The
constant field is automatically selected. Press
ENTER to modify it.
2. Use the Left and Right Arrow keys ( or ) to
select the digits to modify. Use the Up or Down
Arrow keys (
or ) to increment or decrement.
Set the value to:
871 (pulses in 122m).
3. Press ENTER to save the number.
Optionally, set the alarm field to the maximum desired
field speed.
