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.
NOTE
DICKEY-john Servo valves operate at 40 Hz; DICKEY-john
Proportional Valves operate at 100 Hz.
NOTE
The correct number of pulses generated for one revolution
must be determined for sensors other than DICKEY-john.
SERVO
A ball valve or butterfly valve that is driven by an electric motor
gearbox and the valve is installed in the tank return line.
DRIVE FREQUENCY
Specifies the frequency for the proportional valve installed. The
recommended setting for this option should be specified from the
valve manufacturer.
FILTER
The amount of filtering applied to the frequency feedback of the
control channel.
IMPORTANT
It is NOT recommended to change the Filter setting. Any
adjustments could result in the channel not operating
properly. If adjustments are made a valve calibration must
be performed.
