Disable Fertilizer Shaft Alarm
This procedure disables the fertilizer shaft alarm for the
current planting session.
1. Channel Select to Fertilizer .
2. Push and hold the Stop/Reset button for 5 sec-
onds. The console displays “OFF” and beeps twice,
indicating that the function is disabled.
The function remains disabled until power is lost. This is
the recommended setting for V300F drills that are not
presently applying fertilizer.
Note: There is no key sequence to re-enable fertilizer
shaft alarm during the current session. Cycle pow-
er to restore it.
To disable fertilizer alarms in a manner that is preserved
across power cycles, set the shaft rate (pulses per revo-
lution) to 0 (page 64). This is the recommended setting
for V300 drills, which have no fertilizer system (but do
have the shaft sensor lead, which would otherwise
always report 0 rpm, resulting in nuisance alarms).
Fertilizer Alarm Speed Threshold
The default alarm threshold is 0000 rpm (shaft stopped).
If you want an alarm at some low speed other than
stopped, change the threshold rpm as follows:
1. Channel Select to the Fertilizer channel.
2. Press and hold the button to enter Program
Mode 1.
The threshold rpm displays after 3 seconds.
3. Continue holding the button and press to
select the digit to change.
Hold
to change the selected digit.
Release to select the next digit, and repeat as
above.
4. Release both buttons when done. The instrument
returns to the normal display mode.
