SAS Symptoms

SAS Symptom 2
“A Tracker stops working.”
Probable Cause
Defective Tracker.
1. Check SAS cable connections at each tracker.
2. Turn off Control Box and swap tracker showing error
with another tracker on the SAS. (Tracker number is on
the cable at the tracker connector.) Turn the Control
Box back on to reset SAS. If error number moved
positions with the swapped tracker, then the tracker is
the problem. See Chapter 8 to replace the transducer if
necessary.
3. If error continues to display for the same position even
after trackers have been swapped, the tracker connector
or SAS cable is the problem.
4. The defective tracker or SAS cable should be repaired,
but SAS can still be operated without all four trackers
operating. Remember balance point will change if a
tracker is removed.
SAS Symptom 3
“SAS will not lock on grade.”
Probable Cause
Tracker too close to reference or defective transducer in
Tracker.
1. Verify that all cable connections are properly and
securely connected.
2. Check that all trackers are sending out sound waves
(transducer is making ticking sound) and grade lights
are flashing.
