What the Alert is Detecting
(Default)
The travel feedback is within
acceptable limits.
The pressure sensor reading is
outside the functional range of
the sensor.
The pressure sensor reading is
outside the functional range of
the sensor.
The temperature sensor
reading is outside the
functional range of the sensor.
A travel sensor failure or large
travel deviation has resulted in
fallback to pressure control.
The supply pressure has
exceeded the Supply Pressure
Hi Alert Point.
The supply pressure is lower
than the Supply Pressure Lo
Alert Point.

Guidelines for Setting
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.
