Issue
Replacing a CSC2701 compensator with a CSC5252.
Environment
CSC
2701
5252
compensator
Cause
The CSC2701 compensator has been superseded by the CSC5252.
Resolution
The conversion is normally fairly straight forward, but can be more complicated if an SVT is used to provide a boost signal.
.
Please note that the link between terminals 34 and 35 is only fitted where a 24 volt actuator is used.
In the chart above the old and the new terminal numbers are shown. If the old controller was connected to an SVT, which provided a boost facility, terminals 1, 4 and 5 were used to achieve this. With the new CSC, this facility is achieved using the "Setup" function. This is achieved by linking SVT terminals 4/5 to 7/8 on the CSC, having first removed the link.
