OPERATOR’S MANUAL
MATERIAL
Target Rate
Target Rate displays the defined application rate set at the configuration
screen and the rate the Diagnostics screen will perform the test.
– Target rate can be adjusted at the Operate screen by pressing the
Increase/Decrease Rate buttons on the switch module to achieve
the desired target rate.
Actual Rate
Actual rate is the rate that is being applied during the test. The Actual Rate
should match or run closely to the Target Rate.
– A wrong actual rate could indicate that a system response should
be performed or a faulty feedback sensor.
Set Point
Set Point, displayed in hertz, is the pulses per second required for the
feedback sensor to achieve the target rate at the manual ground speed set.
– No set point could indicate a configuration issue or faulty master
module.
Filtered Feedback
Filtered Feedback is the actual pulses per second of the feedback sensor
and indicates the PWM signal being sent to the hydraulic control valve.
– No filtered feedback could indicate a faulty feedback sensor.
Pulse Count
Pulse Count reading indicates pulses sent from the feedback sensor to the
rate control module.
Output PWM
Output PWM indicates the current PWM signal and continues to increase
until the desired target rate is reached and then should remain steady when
achieved.
RPM
RPM indicates the revolutions per minute of the conveyor/auger.
Ground Speed Frequency
Ground Speed Frequency identifies the pulses per second coming into the
control module and could indicate a potential problem with the module, not
reading a signal from the sensor, or a speed sensor failure.
Voltage readings from the truck battery are displayed for the following:
– Solenoid Power
– Solenoid Ground
– ECU Power
– ECU Ground
