SYSTEM CONFIGURATION / 57
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.
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.
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.
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
Channel Width is the width for rows assigned to a specific channel. Width
calculation can be determined by number of planter rows assigned to the
channel multiplied by the row spacing.
PRECHARGE TIME
Precharge Time is a specified length of time a control channel will operate
or be active with a minimum precharge ground speed greater than 0 (Refer
to the Ground Speed Setup section for Precharge Ground Speed setup
information). This feature will activate the control when the master switch is
turned ON even without ground speed.
