Configuration
1. The configuration tab sets the Rotation speed and the Dead band.
2. The Rotation speed affects the response time of the valve between set-points.
3. The default condition is 0 seconds "On-time" and 0 seconds "Off-time" achieving continuous rotation speed which
will vary corresponding to the size of your valve.
4. Make sure that the values entered are appropriate to your system to minimize potential for surge.
5. Dead band - The default value is 0.1 mA which may need to be increased depending on the stability of the electrical
signal.
6. Choose the loss of signal mode.
7. Go to 4 mA: CPC will default to the 4 mA position (low set point).
8. Last position: CPC will maintain the last position.
9. Go to 20 mA: CPC will default to the 20 mA position (high set point).
Note: Loss of signal can occur on the SCADA system which generates the 4-20 mA command but at the same time the CPC
can stay powered, so it is important to select the right option. When you have finished your configuration, click on
"Write Configuration".
Your CPC is configured.
