OPERATOR’S MANUAL
ROAD TEMPERATURE ADAPTER (OPTIONAL)
Temperature sensors allow for direct readout of road temperature and
ambient air temperature.
FEEDBACK/APPLICATION RATE SENSOR (OPTIONAL)
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). A liquid
prewetting system only accepts pulsed feedback while higher capacity
anti-icing systems accept either pulsed or analog.
GATE HEIGHT SENSORS (OPTIONAL)
Measures gate height setting in inches and automatically adjusts conveyor
speed to compensate for gate height changes and maintain application
rate.
HYDRAULIC PRESSURE SENSORS (OPTIONAL)
Hydraulic pressure sensors measure the amount of down pressure applied
on the underbody scraper.
FLOW METERS
Flow meter measures the flow rate of material being applied.
VALVE CONTROL OUTPUT
Flex4 rate controllers control PWM hydraulic and Servo valve electric
motors that regulate material flow for accurate control of product application
rates. Granular and spinner channels regulate the hydraulic oil flow rate to a
motor. Liquid channels use various different configurations such as servo
ball valves and electric pumps.
HARNESSES
Harnesses are included that are required for communication between the
console and components. Optional extension harnesses are available for
the Rate Control Module harness and output module harness when
mounted in areas where additional harnessing is required. Electric motor
driver harness is also available.
HOPPER LEVEL SENSOR (OPTIONAL)
A hopper level sensor can be used to trigger an alarm when material falls
below the sensor mounting level.
VIDEO CAMERA (OPTIONAL)
Multiple cameras can be installed in order to monitor dispensed material or
provide aid in backing the vehicle.
