Position 1. Pst Controller is
Error slow to follow
command signal
due to physical
valve wear, such
as tight packing,
stem build-up,
throttling surface
friction or actua-
tor friction.
2. Valve is slow to
follow command
signal due to
large volume
actuator.
3- Valve will not
follow command
signal due to
insufficient or no
air supply.
4- Valve does not
move because
the device's mode
is not set to Nor-
mal.
5-. Valve will not
follow command
signal due to poor
PST controller
tuning for current
valve status.
6- Valve will not
follow command
signal due to PST
controller mal-
function such as
I/P or Relay.
7- Valve will not
follow command
signal due to
in-line obstruc-
tion.

Recommended
Action
1- Perform valve
signature using
ValVue ESD.
2- Perform step
test signature
using ValVue ESD.
Verify that air sup-
ply droop during
filling is less than
15% or the set
pressure.
3- Validate that
the air supply set
to the instrument
is greater that the
spring final + 10
psig.
4- Set the mode to
Normal using Val-
®
Vue ESD or HART
Host.
5- Perform Auto-
tune or Manual
tuning using Val-
®
Vue ESD or HART
Host.
6- Verify if Bias
Out Range or I/P
Out of Range
events are active.
7- Perform valve
signature using
ValVue ESD.
1- Replace the
pushbutton and
display assembly.
