TROUBLESHOOTING GUIDE
SYMPTOM CAUSE ACTION
Display blank, Transmit Neon not
flashing, transducer not pulsing
No power Check power supply, wiring and
voltage selection switch.
No response to programmer. Obstructed infrared interface, or
defective programmer.
Clean enclosure "docking bay"
and programmer magnet slot.
Displays "Short" and "tb:(#)". Short circuited transducer
cable, or defective transducer.
Repair or replace as necessary.
Displays "Open" and "tb:(#)". Transducer not connected. Connect transducer, or remove
Point # from service (P001=0).
Open circuited transducer
cable, or defective transducer.
Repair or replace as necessary.
Displays "Error" and "tb:(#)". Transducer connected wrong. Reverse BLK and WHT wires.
Wrong Transducer (P004). Enter correct value.
Displays "LOE". Weak or non-existent echo. Relocate and / or reaim transducer
at material level or object.
Proceed to "Measurement
Difficulties", ( following page ).
Displays "EEEE". Reading too high. Select larger Units (P005), or
lower Convert Reading (P061).
Reading fluctuates while material
level is still, (or vice versa).
Incorrect measurement
stabilization.
Alter Measurement Response
(P003) accordingly.
See TECHNICAL REFERENCE
Measurement Response.
Reading is fixed, regardless of
the actual material level.
Transducer beam obstructed,
standpipe too narrow, or
transducer mounting resonant.
Relocate and / or reaim transducer
at material level or object.
Proceed to "Measurement
Difficulties", ( following page ).
Material level reported is always
"off" by the same amount.
Incorrect Empty (zero)
reference.
See Empty (P006),Reading Offset
(P063), Offset Calibration (P650),
& Offset Correction (P652)
Measurement accuracy improves
as level nears transducer.
Incorrect Sound Velocity used
for distance calculation.
Use an ultrasonic / temperature
transducer or a TS-3 temperature
sensor.
See TECHNICAL REFERENCE
Sound Velocity.
Reading is erratic, with little or no
relation to material level.
True echo too weak or wrong
echo being processed.
Relocate and / or reaim transducer
at material level or object.
Proceed to Measurement
Difficulties.
