OLUTION
Transducer Interface (TI)
does not power up (green
power indicator is not lit).
The TI power switch is
turned off.
Check that the power switch on the TI front
panel is turned on.
The TI power supply cables
are not connected.
Check that all cables are connected. At the back
of the TI box, the J3 Power must be connected
to a power supply or battery.
The power supply is not
providing power.
If a battery is used, check that the battery is
charged. See “Specifications” in Chapter 1,
“Hardware Overview” for the minimum input
voltage. If an external power supply is used,
check that it is plugged into an AC supply, and
that power is turned on. The fan on the top of
the power supply should be on at all times when
the external power supply is ON.
The 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 turned on, it is likely the fuse has
blown.
The fuse has blown.
The 3A fast-blow fuse is located on the TI front
panel. If input power exceeds the fuse limits, or
polarity is reversed, you must replace this fuse
before the TI 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
