ValVue SVI II AP Quick Start
2. Read Raw Sensor Data:
When the valve is closed the value should be between – 1000 and
+1000 for a reciprocating valve or a 60° rotation rotary valve.
When the valve is at mid-travel the value should be between –1000 and
+1000 for a greater than 60° rotation rotary valve.
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.
Checking the Electronic Module Connections
WARNING
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 applicable connections to the electronics module
connectors are correct. Not all options are available for every model. Refer to
