Digital Input (DI)
Configure Screen
CAUTION If both Position Low Limit and Tight Shut Off are used, the
Position Low Limit must be above the Tight Shut Off.
6. Position Upper Limit The switch is activated whenever the valve position is greater than
the position setting of this switch control.
CAUTION If both Position High Limit and Full Open Above are used, the
Position High Limit must be below the Full Open Above.
7. Manual Mode The switch is activated whenever the SVI II AP is in manual mode,
configure mode, calibrate mode, or diagnostic mode.
The switch can be configured to default as normally open or normally closed.
NOTE The contacts are OPEN when the SVI II AP is unpowered and
may be made to be open or closed when the flag is asserted
after boot.
Digital Input (DI)
The SVI II AP can receive a digital signal that is used by the positioner software. You can
enable the digital input by clicking in the checkbox.
Input Signal Range (AI)
Use this parameter to adjust the current range Input Signal low and high signal values. The
low value must between 3.8 and 14 mA and the high value must be between 8 and 20.2 mA.
Position Retransmit (AO)
The SVI II AP has the ability to retransmit the position signal as an output to another device
with 4 - 20 mA current output proportional to position. The 4-20 retransmit is galvanically
isolated from the 4-20 input on the main board.
