4.16.2.2 Flowmeter Troubleshooting
If having issues with a flowmeter go to the calibration tab and select flowmeter calibration (see
Figure 133).
Figure 133. Calibrate Valve Flow Screen
Flowrate Is Erroneous
A.
Remove flowmeter paddlewheel and verify paddlewheel is clean and spins freely.
B. Recalibrate flowmeter see section 5.3 (page 178).
No Flowrate Is Displayed
A.
Observe Flow column readings:
If there is an issue with connection to flowmeter, Flow column reading will be 6553.
If there is no issue with flowmeter connection, Flow column reading will be 0.
(When there is no flow on the system.)
If Flow column reading is reading 6553 and associated valve has a flowmeter, verify
harness connections.
B. If SAM displays a COMM loss for associated valve (in Auto Mode) , check power
and/or CAN connections to valve. See paragraph 4.3.5 (page 48) and sec-
tion 4.10.6 (page 115).
