Find Stops
Failed
Find Stops pro-
cess failed.
3 1: When calibrating stops
(Zero / Span) the travel sen-
sor moved outside the
acceptable limits.
2: A procedure timeout
occurred due to an
extremely large volume of
actuator to displace.
3: Valve position could not
stabilize when deenergiz-
ing or when energizing the
actuator.
1: Using ValVue or HART
Host, verify that travel sen-
sor counts is 0 +/– 1000
with the valve closed. For a
90° valve, measured sen-
sor count is done at 50%
travel.
2: Using ValVue or HART
Host, performs a Manual
Stop calibration.
3: Verify that air supply is
adequate. Verify that
accessories (boosters,
quick exhausts, etc.) are
not creating instability.
AUTOTUNE_FAI
LED
Autotune
Failed
Self tuning
failed to con-
verge on
acceptable
parameters.
3 1: When performing an
Autotune, procedure failed
to complete due valve hys-
teresis beyond 50 %.
2: Air supply is insufficient.
3: Air supply droops signifi-
cantly during actuator fill-
ing.
1: Using ValVue or HART
Host, perform an Auto-
tune with an aggressive-
ness level between 2 and 4.
Or manual tune the
parameters according to
the instruction manual.
2: Increase air supply
above spring final value +
10 psig.
3: Perform 5 to 10 % steps
and observe air supply
gauge on the controller.
STD_
DIAGNOSTICS_
FAILED
Std Diagnos-
tics Failed
3 When running a Standard
Actuator Signature, the
device failed to move the
valve between 10 % to 90
%.
1: Selected speed is too
slow. Increase speed for
the test by increments of 1.
2: Insufficient Air supply.
EXT_
DIAGNOSTICS_
FAILED
Ext Diagnos-
tics Failed.
3 When running a Extended
Actuator Signature, device
failed to move the valve
between the configured
travel.
1: Selected speed is too
slow. Increase the speed
for the test by increments
of 1.
2: Insufficient air supply.
