68 / SYSTEM CONFIGURATION
Servo
A hydraulic valve that is opened and closed by an electric motor gearbox.
NOTE: DICKEY-john Servo valves
operate at 40 Hz; DICKEY-john
Proportional Valves operate at
100 Hz.
Drive Frequency
Drive Frequency specifies the frequency for the proportional valve that is
being used. The recommended setting for this option should be specified
from the specific valve manufacturer.
Input Filter
The Input Filter provides a setting for the amount of filtering applied to the
feedback frequency feedback of the Control Channel.
IMPORTANT: It is NOT recommended that the Input Filter be altered.
Any adjustments could result in the channel not
operating properly. If adjustments are made a valve
calibration must be performed.
NOTE: The correct number of pulses
generated for one revolution
must be determined for sensors
other than DICKEY-john.
Sensor Constant
Sensor Constant establishes the number of pulses for one revolution of the
metering unit. If a standard DICKEY-john application rate sensor is used,
the value should be set to 360.0.
Gear Ratio
Gear Ratio specifies the actual ratio from the application rate sensor to the
output shaft. This specifies the number of revolutions the application rate
sensor turns in relation to one revolution the final output shaft turns.
Number (#) of Seed Rows
Allows entry of a specific number of seed rows to the control channel. Row
assignment is given a priority based on the channel and will be assigned
sequentially thereafter. Channel 1 will always be assigned to the first set of
rows, Channel 2 the next set of rows, and so on. This will disable the row
alarms when a respective channel is turned off.
Channel Width
Granular Seeding
Channel Width requires a manual entry of the implement width for rows
assigned to a specific channel.
