L. Proc L.
(Low Process Pressure
Limit)
It is applicable only if the Process Pressure Sensor
is present (“Proc. S” is not set to “None”).
It defines the threshold for the generation LPP
alarm. See Section 8 for details.
The pressure measurement unit (bar or psi) is
determined by the setting of the “Pres. M.U.”
parameter.

FST. Cyc. L.
(FST Cycle Limit)
It defines the threshold for the generation FSCL
alarm. See Section 8 for details.

FST Cyc. C.
(FST Cycle Count)
It is a counter of the FST. It is increased by 1
each time that an Opening or Closing FST is
performed. It can be reset.

FST. Ab. C.
(FST Absolute Count)
It is a counter of the FST. It is increased by 1
each time that an Opening or Closing FST is
performed. It cannot be reset.

PST En.
(PST Enabled)
If it is set as “Yes” it is possible to perform the
PST otherwise the commands “Baseline PST”
and “Manual PST” do not work.
If it is set as “No”, “PST Pos. %” = 0.0%, “PST Pr.
%” = 0% and “PST Time %” = 0%, it’s possible to
perform the SOV Test.
See Section 5.1.6 for details.

PST Set.
(PST Setpoint)
It defines the position to be reached during
the PST. It must be considered that 100% cor-
responds to the fully open and 0% to the fully
closed position.
This parameter affects the “duration” of the PST
time window. It is recommended to perform a
new “Baseline PST” after changing this param-
eter to better compare the next PSTs.

PST Pos. %
(PST Position Hyster-
esis)
It defines the threshold for the PSSP alarm.
See Section 8 for details.
If it is set equal to 0.0%, “PST En.” = “No”, “PST
Pr. %” = 0% and “PST Time %” = 0%, it’s possible
to perform the SOV Test.
See Section 5.1.6 for details.

PST Pr. %
(PST Pressure Hyster-
esis)
It defines the tolerance for the generation of the
following alarms: PSLB and PSHB. See 8 for details.
If it is set equal to 0%, “PST En.” = “No”, “PST Pos.
%” = 0.0% and “PST Time %” = 0%, it’s possible to
perform the SOV Test.
See Section 5.1.6 for details.

PST Time %
(PST Time Hysteresis)
It defines the tolerance for the generation of the
following alarms: PSBB, PSFB, PSST and PSFT.
See Section 8 for details.
This parameter affects the “duration” of the PST
time window. It is suggested to perform a new
“Baseline PST” after changing this parameter to
better compare the next PSTs.
If it is set equal to 0%, “PST En.” = “No”, “PST Pos.
%” = 0.0% and “PST Pr. %” = 0%, it’s possible to
perform the SOV Test.
