SPINNER CHANNEL CONFIGURATION (F8)
Configuration parameters specify actuators and sensors used along with
performance specifications. These values do not change unless the system
hardware changes or the related calibration routines are rerun.
1. From the keyboard, press F8 to display the Spinner Configuration
screen.
2. Edit the parameters on the screen.
– UNLOAD - YES enables or NO disables the spinner during
unloading.
– NO GND SPD - YES enables spinner operation when ground
speed is zero; NO disables at zero speed.
– DRV FREQ (Drive Frequency) - Represents the valve
manufacturer’s suggested drive frequency, as shown on the valve
specification sheet.
– PULSE FDBK (Pulse Feedback) - YES indicates a pulsed
feedback sensor for closed loop control. NO indicates an open loop
control.
– SPIN CON - Number of pulses per spinner revolution.
– BLST RATE (Blast Rate) - If set to 0%, the SPREAD WIDTH
ADJUST knob position determines the spinner speed. Other values
indicate the percentage of maximum spinner speed when Blast is
pressed, regardless of knob setting.
– SYS RSPNS (System Response) - Adjusts the control system
response time to the hydraulic and mechanical systems for a
particular spreader vehicle.
– VALV BOOST (Valve Boost) - Increases the system gain initially
applied to the control channel to reach final operating speed (target
APR) as quickly as possible.
– AFILT - (A Filter) - Minimizes the effects of electrical noise and
mechanical vibrations on the feedback signal. The smaller the
number, the greater the degree of filtering. The value can be
manually fine tined for best results.
– PWM OFFSET – Defines valve operating starting point.
– PWM SAT – Defines valve operating end point (maximum position).
PWM OFFSET and PWM SAT are manually set for proportional
valves. The Proportional Valve Spinner Procedure determines the
actual values (See System Calibration section).
– GSRS Enable - The GSRS Mode (Ground Speed Related Spinner)
enables the Control Point® to regulate the spinner speed related to
ground speed and run closed loop. By controlling the spinner
according to ground speed, the material can be dispersed at zero
velocity.
– GSRS SLOPE - Spinner revolutions per MPH.
– MAX GSRS - Determines the scaling of the spinner bar graph on
the Operate screen. A full bar graph indicates the max GSRS
speed has been exceeded. No alarm is associated with this
constant.
