Yara N-Sensor V3.10 Operation Manual
Send zero rate: Determines whether you want to send a zero rate command to the
controller when you press the Stop key on the work screen. It is recommended to
select “yes” unless your controller cannot handle zero rates properly. Some con-
trollers, especially those connected to sprayers, might display an alarm message
when they receive a zero rate.
Signal delay: The application rate calculated by the N-Sensor usually has to be de-
layed several seconds before it is sent to the controller in order to match the
scanned and the treated area. As a rule of thumb, the signal delay can be calcu-
lated as follows:
Working width: The distance between two tramlines. This information is not required
for the N-Sensor operation itself, but will be used by the mapping software for
processing the application map afterwards.
Signal delay = d / v - t
s
- 2 [s]
d: distance sensor - centre of spreading pattern [m]
v: tractor speed [m/s]
t
s
: time constant spreader [s] (usually 1...2 s for granular spreaders)
3.2 N-Sensor submenu
Press the N-Sensor... button to open the N-Sensor submenu. This menu provides set-
tings and diagnosis for the N-Sensor itself.
Application mode: The Application mode setting determines how the N-Sensor handles
prescription maps. Note that only the default Sensor (standard) setting works without
prescription maps. For the other settings it is required to properly prepare the pre-
scription map and to link it to the current task. Refer to section
6 for further read-
ing.
