Troubleshooting Guide
(Cont.)
C. Flow meter pulses incorrect In the System Setup Mode, move to
the Flow Meter Pulses section on
page 16. Enter the factory flow meter
pulse rate located on the tag
accompanying the flow meter.
D. Speed sensor installed incorrectly One or more of the wheel sensor
magnets are not consistently sending
a pulse to the monitor.
The distance between the sensor and
the magnets is incorrect. Ground
debris can accidentally move the
sensor out of position. The red LED
on the back side of the sensor should
be lit when placed within the correct
distance from the magnets.
(See Installing the Speed Sensor on
page 4)
A proximity sensor has an orange
LED on the top of the sensor that
should be lit when placed within the
correct distance from the sensing
surface.
E. Radar incorrectly installed Precise installation of the radar is
critical to its working correctly.
Thoroughly review the manual
provided with the radar sensor you are
using.
5. No regulation in Auto mode A. No speed sensing Check speed sensor to ensure it is
sending pulses to the controller.
Check the Speed Sensor Calibration
section in the System Setup section
on page 17 to ensure speed sensor is
correctly calibrated.
B. Regulating valve malfunction Check wiring from controller to the
regulating valve. Make sure there is
voltage to the regulating valve.
Both wires leading to the regulating
valve are 12V (+). With the Master
Switch on, and the console set to
MAN mode when either the
or
key is pushed, the appropriate wire
goes to ground (-) to complete the
circuit.
