TROUBLESHOOTING CHART
SYMPTOM CAUSE ACTION
Display blank, Transmit Neon
not flashing, transducer not
pulsing.
No power. Check power supply, wiring, ac
selection switch positions, power
fuse F4 or F5.
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 Correct 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 re-aim transducer
at material level
or object.
Proceed to Measurement
Difficulties.
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 acoustic beam
obstructed, standpipe too
narrow, or transducer
mounting resonant.
Relocate and / or re-aim
transducer at material level
or object.
Proceed to Measurement
Difficulties.
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 accurracy
improves as level nears
transducer.
Incorrect Sound Velocity
used for distance calculation.
Use an ultrasonic / temperature
transducer or a TS-3 temp. 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 re-aim
transducer at matrial level
or object.
Proceed to Measurement
Difficulties.
Date & time (P008 & P009)
are fixed at 70:01:01 &
00:00:00 respectively
clock module life has expired replace
