SIS Options
D Auto Test Interval—This is the interval of time (in days) between partial stroke tests that are automatically run by the
digital valve controller, subject to the device being powered up. A value of 0 disables this feature.
D LoopInitiated PST—When this feature is enabled, the digital valve controller will run a partial stroke test if the loop
current is set to within +/0.5% of the PST trip point. The loop current must remain at that point for the duration of
the test. To abort the test, the loop current must be returned to the normal or tripped current. This feature is
disabled by default. This feature is not available when a looppowered local control panel is installed.
PST Trip Point (ETT) - This is the point at which the loop current must be set to run a partial stroke test for
energizetotrip applications. This value is not configurable.
PST Trip Point (DETT) - This is the point at which the loop current must be set to run a partial stroke test for
deenergizetotrip applications. This value is not configurable.
D Device Power Up Reset—This defines the power up behavior of the DVC6200 SIS. Auto Reset allows the valve to
track the command signal when power is applied to the device. Manual Reset will lock the device in its safety
position until the digital valve controller is reset.
If Manual Reset is selected, its state can be determined from the status monitor by monitoring the Locked In Safety
Position alert.
When Auxiliary Terminal Action is set to SIS Local Control Panel, Device Power Up is set to Manual Reset and cannot
be changed to Auto Reset.
The reset signal depends on how the AUX terminals are configured. If configured for SIS Local Control Panel, the
digital valve controller can be reset by pressing the button next to the green light on the LCP100. If configured as
Push Button Partial Stroke, the digital valve controller can be reset by shorting the AUX terminals for more than 3
seconds but less than 10 seconds. The device cannot be reset from the AUX terminals if they are configured
otherwise.
D Action on Failed Test—This displays the action taken by the instrument if a communication timeout occurs. Values
are Ramp Back or Step Back.

Output Terminal Configuration
D Output Terminal Enable—If using the output terminal for a Position Transmitter or Switch output, this must be
Enabled.
D Function—The output terminals can be configured as one of the following:
Transmitter - 420 mA output that represents 0100% of the calibrated valve travel.
Limit Switch - Discrete switch (1A max) that trips at a configurable point within 0100% of calibrated valve travel.
Alert Switch - Discrete switch (1A max) that trips based on a configurable device alert.
D Fail Signal—Should the output circuit fail to operate properly; the output will attempt to drive to a known state.
Depending on the nature of the failure, the circuit may or may not be able to achieve this fail state. When
