## How to use the Position Offset at Single Valve

If the User wants to set a Position Offset, than the first step would be to “Enable” the “Position Adaption”. This can be done with the CPA4 via Parameters.Valve.PositionAdaption.Enable set to “TRUE” or via RS232 Command – see Chapter Set Position Offset via RS232

The Parameter “Actual Position”, what is shown in picture bellow, is a possibility for the user to show the Adapted Position or the Real Position of the Valve.

Actual Position: | Real | = | Position Setpoint + Offset
| Adapted | = | Position Setpoint

Picture : Actual Position - Option

Now, if the Position Adaption is «Enabled» the user can set under the Parameter Parameter.Valve.PositionAdaption.Offset the desired Offset.

For example the User want to set an Offset = 5 and have selected the Option Actual Position = Real at Position Setpoint = 0.

In this example is an Offset = 5 set and the Actual Position = Adapted at Position Setpoint = 40.

The Position Offset is not active, if an Open or Close command is processed or the Valve is in Control Mode: Open or Close.
