Travel Accumulator
D Travel Accumulator Alert Enable—Yes or No. Activates checking of the difference between the Travel Accumulator
value and the Travel Accumulator Alert Point. The Travel Accumulation Alert is set when the Travel Accumulator
value exceeds the Travel Accumulator Alert Point. It is cleared after you reset the Travel Accumulation to a value less
than the alert point. Factory default is No.
D Travel Accumulator—Records the total change in travel, in percent (%) of ranged travel, since the accumulator was
last cleared. The value of the Travel Accumulator increments when the magnitude of the change exceeds the Travel
Accumulator Deadband. See figure 4‐4. You can reset the Travel Accumulator by configuring it to zero.
D Travel Accumulator Alert Point—The value of the Travel Accumulator, in percent (%) of ranged travel, which, when
exceeded, sets the Travel Accumulator Alert.
SIS Alerts (Instrument Level ODV)
Field Communicator Configure > Detailed Setup > Alert Setup > SIS Alerts (1‐2‐3‐6)
Note
SIS Alerts are only available for instrument level ODV.
D PST Press Limit—Partial Stroke Test 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.
D Press Dev Alrt Enab—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.
D Press Dev Alrt 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.
D Press Dev 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.
