What the Alert is Related Parameters and
Detecting
The travel feedback is within Self Test Shutdown (No)
acceptable limits. Shutdown Recovery (Auto)
Self Test Shutdown (No)
The pressure sensor reading
Shutdown Recovery (Auto)
is outside the functional range
of the sensor.
None
The pressure sensor reading
is outside the functional range
None
of the sensor.
The temperature sensor
reading is outside the None
functional range of the sensor.
A travel sensor failure or large
travel deviation has resulted in None
fallback to pressure control.
The supply pressure has
exceeded the Supply Alert Point (145 psig)
Pressure Hi Alert Point.
The supply pressure is lower
than the Supply Pressure Lo Alert Point (19 psig)
Alert Point.

Using PlantWeb Alerts
Guidelines for Setting
(Default)
Double Acting Actuators— Enable the
alert and configure it to report in the
Failed Alert Category. Self Test
Shutdown is generally not enabled.
Single Acting Actuators—
If Travel / Pressure Control is configured
as Travel with Pressure Fallback: enable
the alert and configure it to report in the
Maintenance Alert Category. Do not
enable Self Test Shutdown.
IIf Travel / Pressure Control is
configured as Travel: Enable the alert
and configure it to report in the Failed
Alert Category. Self Test Shutdown is
generally not enabled.
If Travel / Pressure Control is configured
as Pressure: enable the alert and
configure it to report in the Failed Alert
Category. Enable the Self Test
Shutdown.
For all other Travel / Pressure Control
selections, enable the alert to report in
the Maintenance Alert Category and do
not enable the Self Test Shutdown.

Enable the alert in the Maintenance Alert
Category. Set the Alert Point to which
ever is lower of
a. the maximum instrument pressure
of 145 psig or
b. the maximum actuator casing
pressure.
Enable the alert in the Maintenance Alert
Category.
Double Acting Actuators— Set the
Alert Point above the minimum required
for valve shutoff and no greater than
1 psig below the supply regulator setting
Single Acting Actuators— Set the
Alert Point above the minimum required
for valve shutoff and no greater than
1 psig below the supply regulator setting.
This is generally about 3 psig above the
actuator upper bench set (stroking)
pressure.
