<4. ValveNavi ADMINISTRATION>

Level 4

Allows the user to perform all operations except Download Configuration to YVP.

Level 5

This level is not defined.

Level 6

This level is not defined.

Level 7

This level is not defined.

Level 8

This level is intended for training and should be used cautiously. It grants all of the
privileges of level 4 plus allows access to the Simulation State of the process controller.
(The simulation of the PID Block allows the user to run the process controller without
connecting a process variable input to the YVP and is useful for learning how to operate the
process controller).

WARNING

The simulation state must not be used if the valve is connected in a control loop or the if the
valve is controlling process flow.

The simulation state will permanently remove important control loop configuration
information from the YVP valve positioner. The soft-wired connection between the PID
functions block and its input function block must be restored after simulation is used.

Reconfigure function block links after using simulate. The Clear Device command must be
used when downloading restored configuration.

Level 9

Allows access to all YVP functions. In addition, it is the only level allowed to logon to the
administration program.

The administrator has an account of privilege level 9. There must be at least one user of
privilege level 9 in order to get access to the administration program.
