Change Mode The SVI can be in any of several operating modes:
 Operating: In this mode the SVI responds to the input signal
and positions the valve appropriately (indicator green).
 Manual: In this mode the valve does not respond to the input
signal. Instead it remains stable in one position which is the
position that the valve was when manual mode was entered
or a new position selected by the user (see Setpoint) (indicator
yellow).
 Configure: In this mode you can set configuration parameters
of the positioner or controller (indicator yellow).
 Calibrate: In this mode you can set calibration parameters of
the positioner (indicator yellow).
 Diagnostic: In this mode you can run response time tests, step
response tests, and positioner signatures (indicator yellow).
 Bumpless transfer: This is a transition mode when you select
operating mode from manual mode (see Bumpless Transfer)
(indicator red).
 Failsafe: When the SVI cannot operate correctly the device
goes to the failsafe position and remains in the failsafe mode
until the user intervenes (indicator red).
Menu - Controller
When you right-click on the Controller Monitor tab, a context menu appears (the items that
appear depend on the SVI mode):
 Set Manual – Puts the valve in Manual mode.
 Set Local – Puts the controller in Local mode with a constant, user defined setpoint.
 Set Remote – Puts the controller in remote mode with the setpoint measured from the
signal input.
 Set Output – In Manual mode, allows you to set the valve position. The valve moves to
where it would go if the controller output were set the entered value.
 Report Setup – Allows you to select a report file and a report printing program.
 Report – Generates a report of the SVI parameters.
 Detach Trend – Removes the Trend display from the tabbed dialog and creates a
separate display.
 Help – Displays the help file at the Controller Monitor tab instructions.
