Step 5: Verify Wiring Connections

See Appendix C: Determining an SVI Positioner Compliance Voltage in a Control System
on page 58.
CAUTION
NOTE

Step 6: Configuration

This section describes configuration using the local user interface pushbuttons. You can also
use ValVue and a PC with a HART
Software and the SVi1000 on page 46 describes ValVue software functions.
Prior to changing the SVi1000 configuration, check the existing configuration. Use the
procedures that follow to: run auto stops, run open stop adjustment and perform preset or auto
tune.
WARNING

Auto Find Stops

The process first exhausts the actuator and measures the position, then fills the actuator and
measures the position. From these measurements the valve position is determined. Correction
can be made for nominal valve travel if it is less than full travel. To perform auto find stops:
1. Set the air action (0-7 for ATO or 8-F for ATC).
2. Press auto find stops button until green LED 1 illuminates, then release (approximately 2
seconds to turn on and release before 7 seconds). The unit goes into a Commission Process
and green LED 1 blinks until the process completes. The auto find stops process occurs.
When the process is complete, the unit automatically returns to Normal mode.
Press Cancel to abort the process and the green LED 1 goes off, the device returns to
Normal mode and no changes occur.

Improperly or inadequately grounded installations
can cause noise or instability in the control loop. The
internal electronic components are isolated from ground.
Grounding the case is unnecessary for functional
purposes but grounding the case may be necessary to
conform to local codes.
For split range installations the output voltage must be
sufficient to operate two positioners (11 V @ 4 mA, 9 V @
20 mA) and the expected voltage drop in the cable.

These procedures can cause the valve to move. Before
proceeding, ensure the valve is isolated from the process.
Keep hands clear from moving parts.
