94 / SYSTEM CONFIGURATION
DRIVE FREQUENCY
Drive Frequency specifies the frequency for the proportional valve that is
being used. The recommended setting for this option should be specified
from the specific valve manufacturer.
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 altered.
Any adjustments could result in the channel not
operating properly. If adjustments are made a valve
calibration must be performed.
PRESSURE DROP
Pressure Drop is the difference in pressure sensor mounting location to the
seed disk. Default is 0.
PRESSURE SLOPE
Pressure Slope is the change in pressure sensor voltage to a frequency
readable by the IntelliAg system and measured in inches of H
2
0. This
setting should only be adjusted by qualified personnel.
PRESSURE OFFSET
Pressure offset takes a zero point reading providing a frequency when the
fan is off. Typical offset reading is approximately 800 Hz. If the planter
pressure gauge reading does not match the IntelliAg pressure offset,
control rates may not be exact.
Press the Zero Pressure button to calculate frequency.
PLANTER SELECTION
Planter Selection allows the selection of the planter type and adjusts to the
the appropriate calibration settings automatically.
SENSITIVITY ADJUST
Sensitivity Adjust is used to increase or decrease the calibration parameters
in the ranges of -10 to +10. The system default is 0 and is the middle point
where no adjustments are made. Increasing the response time to a positive
number makes the system respond quicker. Decreasing the response time
to a negative number makes the system respond slower.
IMPORTANT: Sensitivity adjustment should be changed only by
authorized personnel. Increasing sensitivity can cause
the system to be unstable. Decreasing sensitivity can
cause the system to be nonresponsive.
