AUXILIARY SYSTEM RESPONSE AND DROP TEST
Additional auxiliary channels 3 and 4 are available for granular or liquid rate
control. Channel Setup screens require the same configuration parameters,
calibration, and drop test requirements as channels 1 and 2. Refer to the
Granular and Liquid Configuration sections for additional information.
SPINNER SYSTEM RESPONSE CALIBRATION
When “F4 Aux S” is assigned as Spinner, performing a Spinner System
Response determines PWM Offset and PWM Saturation values when using
a proportional valve with no feedback sensor to drive the spinner channel.
Spinner calibration allows for open loop or closed loop operation of the
spinner to coordinate spread width knob position with a specific spread
width for lane mile material application.
To perform a Spinner System Response Test:
1. At the System Calibration screen (F6), select Spinner System
Response and follow the onscreen instructions.
2. At the Spinner System Response screen, press “R” to begin test.
3. Spinner will be set to off when the calibration starts. Slowly rotate the
knob clockwise until the minimum spinner speed is achieved.
4. Press R to run.
5. When the desired offset is achieved, press C to capture the offset.
6. Rotate the spinner knob clockwise until the maximum spinner speed is
achieved.
7. Press C to capture the saturation.
8. Spinner calibration is complete. Press D to exit.
NOTE: Calibration Data Sheets are
available in the back of this
manual to record constants.
A warning message indicates material will dispense when
procedure is started. Ensure all personnel are clear before
starting the next step.
