Help
Travel feedback value
is outside expected
limits. If this problem
occurs during
instrument set-up, the
most likely cause is
faulty mounting or
improper adjustment of
the travel sensor. If
this problem occurs
during normal
operation, the most
likely cause is a failure
of the travel sensor or
damaged linkage.
To correct,
1) Insure proper
mounting and linkage
adjustment.
2) Inspect and test
travel sensor
3) Toggle the
transducer target
mode.
If the problem persists,
replace the printed
wiring board (PWB)
assembly.
The pressure sensor
on-board the device
has failed. This may
be due to excessive
supply pressure or
contaminated air.
If it is verified that the
air supply is ok,
replace the printed
wiring board (PWB)
assembly.
The pressure sensor
C
on-board the device
has failed. This may
be due to excessive
supply pressure or
contaminated air.
If it is verified that the
air supply is ok,
replace the printed
wiring board (PWB)
assembly.
The temperature
sensor on-board the
device has failed or
the unit has been
exposed to an
temperature extreme
beyond the
recommended limits.
