Shaft Monitor Operation (Option)
Refer to Figure 32
The optional shaft monitor (page 78) sounds an alarm if
any seed shaft stops for more than 20 seconds.
To operate shaft monitor, turn system on by activating
on-off switch
on monitor head. If seed-cup shaft is
turning, all section lights will be on and the alarm will not
sound.
If any seed-cup shaft stops for 20 seconds, an alarm will
sound and a light on the monitor will flash designating
the failed shaft.
The 20-second delay is to prevent nuisance alarms when
turning at the end of the field. If a failure does occur and
an alarm sounds, remember that you have traveled for
20 seconds without planting.
Acremeter Operation
Refer to Figure 33
The acremeter counts shaft rotations whenever the shaft
rotates - this is with the drill lowered and in motion or
during crank operation. The meter is programmed to
display rotations as acres/hectares, when using all rows,
factory-specified tires and tire inflations. See also the
Electronic Acremeter Manual 152-314M.
Unusual conditions and/or non-standard row spacings
can cause the acremeter tally to vary from actual acres
planted.
Normal Operating Sequence
Note: The acremeter counts rotations during drill
calibration (and if so, can be useful for calibration,
although the meter must be on, or moved to, the
shaft being cranked).
1. Record the acremeter reading at the start of planting
(and after calibration). The large “12345.6” format
display is the grand total area planted since meter
installation. If the display is blank, see “Dormant
Display”” below.
