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).
