PST Pressure Limit—Defines the output
pressure that will cause the partial stroke test to stop.
For actuators that vent from the test starting point, the
pressure limit will be a minimum value. For actuators
that fill from the test starting point, the pressure limit
will be a maximum value.
Pressure Deviation Alert Enable— Select Yes
or No. This alert notifies a monitoring system when a
deviation in the actuator pressure has occurred. This
is used when the instrument is controlling via pressure
(Pressure Control Mode is enabled) to the actuator
(rather than valve position) to prevent saturation of the
pneumatic output. When enabled, this alert checks the
difference between the target pressure and the actual
pressure. If the difference exceeds the Pressure
Deviation Alert Point for more than the pressure
deviation time, the Pressure Deviation Alert is set. It
remains set until the difference between the target
pressure and the actual pressure is less than the
Pressure Deviation Alert Point. The pressure deviation
alert point and deviation alert time are configurable
and can be disabled altogether. Factory default is Yes.
Pressure Deviation Alert Point— The alert
point for the difference between the pressure target
and the actual pressure. When the difference exceeds
the alert point for more than the Pressure Deviation
Time, the Pressure Deviation Alert is set. After
completion of the Setup Wizard or Auto Travel
calibration a default value of 2 psi is set. This will
generate an alert when the actuator pressure is not
within
$
2 psi of the target pressure.
Pressure Deviation Time— The time, in
seconds, that the pressure deviation must exceed the
Pressure Deviation Alert Point before the alert is set.
The Pressure Deviation Time is set to 30 seconds by
default.
Alert Record
(1-2-3-6) HC, AD, and PD
(1-2-3-7) ODV
To be recorded, an alert must both be enabled for
reporting, and the group in which it resides must be
enabled for recording. Table 4-8 lists the alerts
included in each of the groups. When any alert from
an enabled group becomes active, active alerts in all
enabled groups are stored.
Alert Record Has Entries Enable—Yes or No.
When enabled indicates when an alert has been
recorded. Factory default is Yes.
Alert Record Full Enable—Yes or No. When
enabled indicates when the Alert Record is full.
Factory default is No.

clear the alert record, all alerts in enabled groups must
be inactive.
Alert Groups

(1-2-3-7-5) ODV
Failure Group Enable—Permits enabling the
Failure Alert group. Factory default is Yes. Table 4-8
lists the alerts included in each of the groups.
Valve Group Enable—Permits enabling the Valve
Alert group. Factory default is Yes. Table 4-8 lists the
alerts included in each of the groups.
Miscellaneous Group Enable—Permits enabling

groups.
Status (1-2-4)
Select Configure, Detailed Setup, and Status. Follow
the prompts on the Field Communicator display to
configure the following parameters: Instrument Time,
Calibration and Diagnostics, Operational, and
Integrator Saturation.
Instrument Time (1-2-4-1)
Inst Time Invalid Enable—Yes or No. When
enabled indicates if the Instrument Time Invalid alert is
active. Factory default is Yes.
Instrument Date and Time—Permits setting the
instrument clock. When alerts are stored in the alert
record, the record includes the time and date. The
instrument clock uses a 24-hour format.
