CONTROL MODE
Auto-Control Channel is calculating application rates based on
ground speed and row spacing under normal operating
conditions.
MANUAL WITH FEEDBACK -
Overrides the current system
when not operating properly, e.g. faulty coil. Using the
Increment/Decrement buttons at the Main Operate screen will
set the rate for the control channel. Manual Mode with Feedback
shows the actual application rate applied based on actual ground
speed and constants.
MANUAL WITHOUT FEEDBACK -
Overrides the current
system when not operating properly, e.g. bad feedback sensor.
Using the Increment/ Decrement buttons at the Work Screen will
set the 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
Specifies the frequency for the proportional valve installed. The
recommended setting for this option should be specified from the
specific valve manufacturer.
INPUT FILTER
An adjustment setting for the amount of filtering applied to the
feedback frequency feedback of the control channel.
IMPORTANT
It is NOT recommended to change the Input Filter. Any
adjustments could result in the channel not operating
properly. If adjustments are made, a valve calibration
must be performed.
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
