Checking the Air Supply
Use this procedure to check the air supply.
1. Turn on the air supply.
2. Adjust the filter regulator.
Supply pressure must be a minimum of 10 psi greater than the spring range of the
actuator but may not exceed the rated actuator pressure. Refer to the valve or
actuator instruction manual.
3. Inspect the tubing connections between the filter-regulator and the positioner for
leaks.
4. Verify that the tubing is not bent or crushed.
5. Verify that all fittings are leak tight.
NOTE
Do not use Teflon pipe seal tape. The Teflon tape can shred into
particles that are harmful to the pneumatic components.

Do not remove the instrument cover or connect to an electrical
circuit in a Hazardous Area unless the power is disconnected.
All connections to electronic module in the SVI II AP are made through the terminal board. The
SVI II AP terminal board has a terminal block with cage clamp connectors. Confirm that all appli-
cable connections to the electronics module connectors are correct. Not all options are available
