Instruction Manual
D103412X012
VST Incoming Pressure Threshold defines the actuator pressure at which a partial stroke test will abort during the
incoming stroke (see figure 4‐6). This prevents the DVC6200f from exhausting (or building) excessive pressure from /
to the actuator in an attempt to move a stuck valve.
D Full Stroke
Full Stroke Ramp Rate (FST_RAMP_RATE [156]) is the rate at which the valve will move during the full stroke test.
FST Wait Time (FST_WAIT_TIME [160]) is the amount of time to wait for the valve to move to the normal end after
initiation of the full stroke test.
Full Stroke Breakout Timeout (FST_BREAKOUT_TIMEOUT [155]) is the user configured amount of time before which
the valve must leave the normal end during a full stroke test.
PST Prohibited
A partial stroke test will not be initiated if any of the following user-configurable conditions are active:
1. Check Bit Alert
2. Drive Current
3. Drive Signal
4. Processor Impaired
5. Travel Sensor
6. Output Pressure sensor
7. Supply Pressure Sensor
Auto PST
D Auto PST Current Time (PST_AUTO_CURRENT_TIME [152.3]) shows the current time in the instrument.
D Hours to next Auto PST (PST_AUTO_HOURS_TO_NEXT [152.2]) indicates how many hours until the next auto PST.
D Auto PST State (PST_AUTO_STATE [152.1]) displays the state of the auto PST; Disabled, Waiting, Pending, Starting,
and Monitoring.

D Partial Stroke Initial Start Time (PST_INITIAL_START_TIME [137]) defines the date and time when the first PST will
run.
D Partial Stroke Interval (PST_INTERVAL [138]) defines the time between tests.
