Step 5: Verify Wiring Connections
See C “Determining an SVI Positioner Compliance Voltage in a Control System” on page
63.
CAUTION
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.
NOTE
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.
Step 6: Configuration
This section describes configuration using the local user interface pushbuttons. You can also use
ValVue and a PC with a HART
®
modem or a HART
®
Handheld Communicator. 5 “ValVue Software
49 describes ValVue software functions.
Prior to changing the SVi1000 configuration, check the existing configuration. Use the proce-
dures that follow to: run auto stops, run open stop adjustment and perform preset or auto tune.
WARNING
These procedures can cause the valve to move. Before proceeding
ensure the valve is isolated from the process. Keep hands clear
from moving parts.
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.
