GATE HEIGHT SENSOR
The Gate Height Sensor compensates for changes from the original
calibrated gate setting by adjusting the conveyor speed allowing for a more
accurate granular material application. If the gate height is increased, the
conveyor speed will decrease and decreasing gate height will increase
conveyor speed.
The Gate Height Sensor connects to the main harness lead labeled GATE
on the current Control Point
®
harnesses and Pressure on the earlier
harness versions. Software Versions 6.10 and higher have removed
pressure control from the Control Point
®
. The software now utilizes the
pressure sensor input for the Gate Height. Pressure-controlled liquid
systems cannot use the 6.10 or higher version software.
When enabled, the Gate Height will display to the nearest .1 of an inch or 1
centimeter in the lower right corner of the Operate screen.

GATE HEIGHT CALIBRATION
There are seven user-definable Gate Heights to enter that will aid in Gate
Height calibration. Enter seven Gate Height settings that will be used when
spreading material.
Calibration Steps:
1. From the Gate Height Sensor screen, position the arrow at the Closed
position.
2. Set the Gate to Closed.
3. Measure the height at the Closed position and enter the Gate Height
value for the closed setting.
4. Press C to capture the current gate height voltage at the closed
setting.
5. Move the arrow to Setting 1.
6. Set the Gate to the lowest operating Gate Height setting.
7. Measure the height at Setting 1 and enter the Gate Height value for
Setting 1.
8. Press C to capture the current Gate Height Voltage for Setting 1.
9. Repeat 5-8 steps for the Settings 2-5 starting with the next lowest
setting.
