SWIFT 50 GLP Sensors Troubleshooting 79
Errors reported when
TI2STATUS is run. Shunt errors that
TI2STATUS could report. • Reference Bad – a downloaded shunt
reference is zero. This is a calibration
settings problem.
• Shunted Bad – A bridge being shunted
deviated from the shunt reference by more
than the limit. This could be caused by a
sensor failure, transducer cable failure, TI
failure, bad shunt reference setting or bad
shunt tolerance setting.
• Unshunted Bad – A bridge not being
shunted deviated by more than the limit.
This is likely caused by a short in the
transducer or transducer cable.
Zero errors that
TI2STATUS could report. • Bad Angle Offset – the transducer should
have been rotated +/-90 degrees but the
measured angle was different by more than
the limit (currently 2 degrees). This could
be caused by not passing the index mark
before starting the zero, not rotating by the
correct angle, a bad angle sensor or a bad
transducer cable.
• Direction Change – the direction the
transducer was rotated changed during the
zero process. The transducer needs to be
rotated in 90 degree increments the same
direction in each step of the zero process so
data can be collected for each one of the
sensor beams (0, 90, 180 and 270 degrees).
• Missing Data Points – a zero method that
collects data while the transducer is rotated
found too many consecutive missing data
points. This is likely caused by rotating the
transducer too fast.
• Invalid Algorithm – the zero algorithm
specified is not recognized. This is likely
the calibration setting problem that could
be affected by software and firmware
version.
