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.
IMPLEMENT UP
Disabled
The control loop runs regardless of implement lift state. If
sufficient hydraulic capacity is not available, alarms may
trigger if the fan is not maintaining set point.
Locked
When the implement is raised the control loop is stopped and
output is frozen at its previous value. If you don’t have enough
hydraulic capacity and the fan is not maintaining set point
prevents alarms for occurring even though fan is still not
working properly.
