Testing the Flow Meter/Encoder Cable
1.
Enter a meter cal of 1 in liquid or direct injection modes, or density of 1 and spreader constant of 0 in
granular mode, on the Calibration Settings screen in the Product Control menu.
2.
Touch the Volume/Area Settings button and note the total volume for each product node connected to the
CANbus.
3.
Turn the boom and master switch On.
4.
With a small jumper wire (or paper clip), short between the 2 o’clock and 6 o’clock sockets with a ‘short-no-
short’ motion. Each time contact is made, the total volume number should increase by increments of 1 or
more.
5.
If the total volume value does not increase, remove the section of cable and repeat the test at the connector
that is the next closest to the node. Replace the defective cable as required.
6.
Verify the pin connection and voltage from the previous chart.
7.
If all of the cables test ‘good,’ replace the rate sensor.
Note:
After testing is complete, re-enter the correct cal values before starting an application.
