Troubleshooting
The battery or power supply
wiring is reversed.
If using a car battery, check that the wiring is
correct. If the wiring has been reversed and the
power switch was turned on, it is likely the fuse
has blown.
The main fuse has blown.
The 3A fast-blow fuse (F3) is located on the
rear of the Induction Power Source. If input
power exceeds the fuse limits, or polarity is
reversed, you must replace this fuse before the
Induction Power Source can be used again.
The battery or power supply
is not providing power
Verify that the power supply is turned on or that
the battery is sufficiently charged and can
provide the required amperage.
One power indicator
(Channel 1 or Channel
2) is not lit
A secondary fuse (F1 or F2)
is blown.
The 1A fast-blow fuses (F1 and F2) are located
on the rear of the Induction Power Source. If the
fuse is blown, you must replace the fuse before
the Induction Power Source can be used again.
FAIL indicator blinks.
An internal failure has
occurred in the TI
electronics.
Boot Error: Turn the TI power off and on to
reboot.
Internal Error: See “Hardware Overview”, for
failure codes relating to FAIL indicator.
Spinning Zero Procedure:
The Bridge Zero indicator
goes out before the wheel
is rotated.
The ZeroAlgorithm is set
for a non-spinning zero.
If the Zero Bridge indicator goes on and stays
on for a few seconds, then turns off, check that it
is set for a non-spinning zero. To use the SWIFT
sensor in the spinning mode, you must change
the ZeroAlgorithm and AngleMode values in
the calibration file. Refer to
Spinning Zero Procedure:
The Bridge Zero and Angle
Zero indicators stay on too
long, or they continue to
blink slowly, even after the
wheel has rotated twice.
The angular output signal is
not reaching the TI. The TI
will wait for the two
revolutions as noted by the
encoder. If the encoder
signal is not reaching the TI,
it may eventually time out
and blink slowly, indicating
a zero failure.
Check that all cables are attached and
undamaged. In particular, check the main signal
cable from the transducer to the TI.
Check that the encoder output is present. The
angle output signal from the TI should be a 0–5
V sawtooth output while the transducer is
spinning at a constant velocity.
The EncoderSize parameter
in the calibration file is set
incorrectly.
Check that the EncoderSize parameter is set
properly for the slip ring (EncoderSize=1) being
used.
The indicators will stay lit if
there is no encoder signal. If
the wheel stops rotating or
the encoder is disconnected
after data collection has
started, the data collection
will time out and blink
slowly.
If this signal is not present, check that the slip
ring/encoder assembly has not been damaged. If
you suspect encoder damage, swap the slip ring
assembly with a known functioning unit to
verify it. If the slip ring/encoder assembly is
damaged, call MTS or replace it with a spare
slip ring assembly.
