E. Feedback Sensors
The feedback sensors send product flow information to the console for accurate
product application. Both granular and spinner channels require pulsed
electrical sensors having an output proportional to the mechanism speed. The
liquid channel accepts either electrical pulsed sensors or analog sensors with
outputs proportional to material flow (pulsed) or system pressure (analog). A
liquid prewetting system only accepts pulsed feedback while higher capacity
anti-icing systems accept either pulsed or analog.
F. Actuator Devices
Actuator devices regulate material flow for accurate control of product applica-
tion rates. Normally, granular and spinner channels regulate the hydraulic oil
flow rate to a motor. Liquid channels use several different configurations. Many
prewetting systems use a DC pump to regulate flow by controlling pump speed.
Other systems use hydraulically driven pumps similar to agricultural applica-
tions.
G. Hopper Level Sensor (Optional)
The optical light beam of this level sensor is blocked by the granular material in
the spreader bed. When the material level falls beneath the sensor mounting
level, a repetitive beep sounds and an appropriate message displays in the
warning/alarm area of the OPERATE screen.
I. Harnesses
The Main Harness assembly connects the Console to the ground speed sensor,
feedback sensors, channel valve (or DC motor) actuators, vehicle battery,
ignition, and additional optional connections (including two-speed axle, hopper
level sensor, and boom sense inputs). An optional Extension Harness, allows
the Main Harness to extend outside the cab, contains duplicate connectors to
permit hookup flexibility. Other extension harnesses are available to allow
flexible sensor arrangement.
