If the actual air piping is different than described above, the functions of the SVP as a positioner
will not be affected. However, various valve and SVP diagnostics usually performed with the
Commstaff will not return accurate information. To enjoy the capabilities of the SVP to the
fullest, piping should match the diagrams and instructions above to maintain the relationship
between the parameter settings described throughout this user manual.
