SYSTEM CONFIGURATION
THRESHOLD SETTINGS
If the actual seeding rate of a row falls below the threshold setting on the
monitor, the row will fail and the alarm will sound.
To set the threshold:
1. Power up the console and wait until startup is complete.
2. Refer to The Minimum Seeding Rate Table for desired threshold
setting.
3. Set the threshold to 2/3 of the nominal planting rate. If the desired
threshold is higher than the allowable setting, then set the threshold to
the highest setting.
4. Momentarily hold the +/- switch in either the “+” or “-” position to
change the threshold adjustment setting. The number of indicator
lamps that illuminate indicate the threshold setting.
– Holding the +/- switch to the “+” position will increase the threshold
setting.
– Holding the +/- switch to the “-” position will decrease the threshold
setting.
NOTE: Changing the tractor speed will
change the seeds per second
planting rate. An alarm will
occur if the tractor speed
decreases so that the seeding
rate falls below the threshold
setting. If the alarm sounds too
often then change the threshold
setting to the next lower setting.
To calculate the minimum seeding rate in seeds per second refer to the
Minimum Seeding Rate Table.
