5100ex Calibration Manual
Description of Calibration Values
6
Note that Jump Start speed is not applied when operating in Dust Control and Herbicide
mode, regardless of this setting.
Sim Speed
The Sim Speed menu item enables or disables the simulated speed operation feature.
The simulated speed operation feature allows for the troubleshooting of the ground speed
based components of the system without having to drive the vehicle. The default value is
Disabled.
Ground Speed Interrupt
The Ground Speed Interrupt menu item enables ground speed interrupt when the auger
is running in manual mode. When ground speed interrupt is enabled, the system will stop
spreading granular material in manual mode when the vehicle is not moving. The default
value is disabled.
Auger
The Auger menu allows you to configure settings for the vehicle’s granular output. These settings
apply across all granular materials. If Config → Application Mode is set to Direct 1 Lane or Direct
3 Lane, this menu will be disabled.
Options
The Options submenu contains settings that apply to the Auger system as a whole, such
as Loop Mode and Pulses per Revolution.
Loop Mode
The Loop Mode menu item sets the granular output into either Closed or Open
Loop Mode. Closed Loop mode monitors the auger feedback sensor to ensure
accurate material displacement. Open Loop mode approximates material
displacement from vehicle speed as well as auger and material calibration
settings. The default value is Open Loop Mode.
If Prewet is enabled, setting the Auger Loop Mode menu item to Open will also
change the Prewet Loop Mode menu item to Open.
Gain
The Gain menu item is a multiplier applied to closed loop granular operation,
used to fine-tune the granular system’s sensitivity to changes in vehicle speed or
granular set rate. A high gain value will cause the granular system to adapt to
changes quickly but might cause the system to overshoot the target RPM. A low
gain value will cause the granular system to adapt to changes slowly but might
cause the system to under apply material until it reaches the target RPM. The
default value is 250.
If the auger is hunting and not settling at a steady speed, try reducing the Gain
value.
The Gain menu item will not be available if the Loop menu item is set to Open.
Pulses/Rev
The Pulses/Rev menu item sets how many pulses from the auger sensor are
expected in 1 revolution of the auger. Pulses/Rev is used in closed loop
operating mode and should be configured as accurately as possible. The default
value is 128 pulses per revolution. The Pulses/Rev menu item will not be
available if the Loop menu item is set to Open.
