Auto Tune
Auto Tune normally takes three to ten minutes and strokes the valve in large and small steps to
set the PID positioning parameters for best response to an input signal change.
This procedure overrides any previous configuration done using presets.
To auto tune the SVi1000:
1. Set the Configuration Selector Switch to the auto tuning parameter (Figure 24):
0 for an ATO valve (Air to Open application)
8 for an ATC valve (Air to Close application).
Figure 24 Configuration Selection Switch
2. Press the Autotune button until green LED 3 lights, then release ( approximately 2
to 7 seconds ). The unit goes into a Commission Process and green LED 3 blinks.
The autotune process occurs.
When the autotune process is complete the unit automatically returns to Normal
mode.
Press
Cancel to abort the process and the green LED 3 goes off, the device returns
to Normal mode and no changes to the tuning parameters occur.
