44 / CHANNEL SETUP
CONTROL MODE
AUTO-Control Channel is calculating application rates based on ground
speed and row spacing under normal operating conditions.
MANUAL W/FEEDBACK-Overrides the current system when not operating
properly, i.e., faulty coil. Using the Increment/Decrement buttons at the
Main Work screen will set the rate for the control channel. Manual Mode
with Feedback shows the actual application rate being applied based on
actual ground speed and constants.
MANUAL W/O FEEDBACK-Overrides the current system when not
operating properly, i.e., bad feedback sensor. Using the Increment/
Decrement buttons at the Main Work screen will set the flow rate for the
control channel. No application rate feedback will display.
DRIVE TYPE
PWM (Pulse Width Modulation)
A valve, usually hydraulic, which varies the oil flow to a hydraulic motor
proportioned to electric current supplied. This type of valve consists of a
flow cartridge and coil assembly.
DRIVE FREQUENCY
Drive Frequency specifies the frequency for the proportional valve being
used. The recommended setting for this option should be specified from the
specific valve manufacturer.
NOTE: DICKEY-john proportional
valves operate at 100 hz. 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 manually
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. GEAR RATIO
Gear Ratio specifies the actual ratio from the application rate sensor to the
seed meter. This specifies the number of revolutions the application rate
sensor turns in relation to one revolution the seed meter turns.
SENSOR CONSTANT
Sensor Constant establishes the number of pulses for one revolution of the
application rate sensor. If a standard DICKEY-john application rate sensor is
used, the value should be set to 360.0.
