Configuring the Granular Channel
Check each following item for a desired setting.
– SPR CON (Spreader Constant) – Represents the number of pulses
generated by the application rate sensor per pound of material (P/
LB) discharged from the spreader.
The spreader constant differs for each granular material, spreader
vehicle, and gate height setting. If the spreader constant is known,
keyboard enter the value so that running the GRANULAR
CALIBRATION routine for this material is unnecessary. If the
spreader constant is unknown, leave the displayed value. The
correct value is automatically corrected later, during GRANULAR
CALIBRATION.
– CAL GT HGT (Calibration Gate Height) - Displayed only if optional
Gate Height Sensor is Enabled. If Enabled, the Calibration Gate
Height valve displayed is the setting of the gate height in inches
when the spreader was calibrated. Refer to page 77 for the
Spreader Calibration procedure.
Changing the original calibrated gate setting by adjusting the
conveyor speed provides a more accurate granular material
application. Increased Gate Height decreases conveyor speed;
Decreased Gate Height increases conveyor speed.
– DRV FREQ (Drive Frequency) – Represents the valve
manufacturer’s suggested drive frequency, as shown on the valve
specification sheet.
