the I/P converter and installing it. If the alert does not clear, replace the I/P converter or the printed wiring board
assembly.
D Critical NVM Failure is active if there is a failure associated with NVM that is critical for instrument operation. If
this alert is active, restart the instrument. If the alert persists, replace the printed wiring board assembly.
D Temperature Sensor Failure is active when the instrument temperature sensor fails, or the sensor reading is
outside of the range of 60 to 100°C (-76 to 212°F). The temperature reading is used internally for temperature
compensation of inputs. If this alert is active, restart the instrument. If the alert persists, replace the printed
wiring board assembly.
D Pressure Sensor Failure is active if any of the 3 pressure sensor readings are outside the range of 24.0 to 125.0%
of the calibrated pressure for more than 60 seconds. If this alert is active, check the instrument supply pressure,
ensure the printed wiring board assembly is properly mounted onto the module base assembly, and ensure the
pressure sensor Orings are properly installed. If the alert persists after restarting the instrument, replace the
printed wiring board assembly.
D Travel Sensor Failure is active if the sensed travel is outside the range of 25.0 to 125.0% of calibrated travel. If this
alert is active, check the instrument mounting. Also, check that the electrical connection from the travel sensor
is properly plugged into the printed wiring board assembly. After restarting the instrument, if the alert persists,
troubleshoot the printed wiring board assembly or travel sensor.
D Supply Pressure Alert is active if the supply pressure falls below the supply pressure alert point.
D Travel Deviation Alert—If the difference between the Travel Target and the Travel exceeds the Travel Deviation
Alert Point for more than the Travel Deviation Time, the Travel Deviation Alert is active. It remains active until the
difference between the travel target and the Travel is less than the Travel Deviation Alert Point minus the Travel
Alert Deadband.
D Pressure Fallback Active Alert is active when the instrument has detected a problem with the travel feedback and
is now controlling the output like an I/P transducer.
PST Abort is a user configurable list of alerts that will abort a PST when encountered during a PST.
D Pressure Threshold, either the outgoing pressure or incoming pressure threshold has been violated.
D High Friction Breakout Pressure, the force required to breakout of the normal end of travel is higher than the user
configured threshold. The breakout is defined as the pressure at which the travel crosses the user configured
breakout travel, either high or low depending on the configured normal end.
D Low Friction Breakout Pressure, the force required to breakout of the normal end of travel is lower than the user
configured threshold. The breakout is defined as the pressure at which the travel crosses the user configured
breakout travel, either high or low depending on the configured normal end.
D Max Travel Exceeded, the test actual travel has violated the user configured maximum travel.
D Minimum Travel not achieved, the actual travel during the test did not achieve the user configured minimum
travel.
D Not Seated, the valve did not return to the normal end as defined by the breakout high or breakout low
depending on the normal end of travel.
D Travel Deviation, the error between the actual valve travel and set point exceeded the user configured value for a
user defined period.
