if the condition that caused the shutdown remains or
until the shutdown trigger is disabled.
Pressure Sensors
Pressure A Sensor Alert
This alert is active if the Port A Pressure Sensor
reading is outside the functional range.
Pressure A Sensor Alert Enable
When enabled Pressure A Sensor Alert Enable
activates the Pressure A Sensor Alert.
Pressure A Sensor Shutdown
The Shutdown Trigger (SHUTDOWN_TRIGGER
[76.1]) permits enabling or disabling Self Test
Shutdown. When enabled, and the Port A Pressure
Sensor Alert is active, the transducer Actual mode is
placed out of service. The instrument will attempt to
drive the valve to the zero power condition and will no
longer execute transducer control function.
Pressure A Sensor Manual Recovery
Shutdown Recovery (SHUTDOWN_RECOVERY
[76.2]) permits enabling or disabling Manual recovery
from Self Test Shutdown. When not enabled, the
transducer block will return to Target mode when
Pressure A Sensor Shutdown clears. If enabled, the
transducer block will remain Out of Service until power
is removed and restored or the user changes the
transducer block target mode to Manual or Auto. In
any case, the target mode will remain Out of Service,
if the condition that caused the shutdown remains or
until the shutdown trigger is disabled.
Pressure B Sensor Alert
This alert is active if the Port B Pressure Sensor
reading is outside the functional range.
Pressure B Sensor Alert Enable
When enabled Pressure B Sensor Alert Enable
activates Pressure B Sensor Alert.
Supply Pressure Sensor Alert
This alert is active if the Supply Pressure Sensor
reading is outside the functional range.
Supply Pressure Sensor Alert Enable
When enabled Supply Pressure Sensor Alert Enable
activates the Supply Pressure Sensor Alert.
Pressure Fallback
Pressure Fallback Alert
This alert is active if a travel sensor failure or a gross
travel deviation has resulted in fallback to pressure
control.
Pressure Fallback Alert Enable
When enabled Pressure Fallback Alert Enable
activates the Pressure Fallback Alert.
Temperature Sensor
Temperature Sensor Alert
This alert is active if the Temperature Sensor reading
is outside the functional range.
Temperature Sensor Alert Enable
When enabled Temperature Sensor Alert Enable
activates the Temperature Sensor Alert.

Supply Pressure
Supply
Supply (SUPPLY_PRESSURE.VALUE [35.2])
displays the instrument supply pressure in kPa, bar, or
psi.
Supply Pressure Hi Alert
This alert is active when the supply pressure exceeds
the Supply Pressure Hi Alert Point.
Supply Pressure Hi Alert Enable
When enabled Supply Pressure Hi Alert Enable
activates Supply Pressure Hi Alert.
Supply Pressure Hi Alert Point
The Supply Pressure Hi Alert is active when supply
pressure exceeds the Supply Pressure Hi Alert Point
(SUP_PRES_HI_ALRT_PT [76.8]).
Supply Pressure Lo Alert
This alert is active when the supply pressure is lower
than the Supply Pressure Lo Alert Point.
