Change Mode When selected, you can change the SVI2 mode. The SVI2 can be in
any of three operating modes:
 Operating- In this mode the SVI2 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 is selected (see Setpoint) (indicator yellow).
 Setup- In this mode you can set calibration and configuration
parameters. Additionally you can run response time tests,
step response tests, and positioner signatures. (indicator
yellow).
Mode
The SVI2 can be in any of several operating modes
 Operating - in this mode the SVI2 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 you (see Setpoint) (indicator yellow).
 Setup - in this mode, the valve does not respond to the input signal and remains stable
unless moved by a command selected by you. In this mode, you can set calibration and
configuration parameters. Additionally, 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 and the positioner has been configured for bumpless transfer. (indicator
red).
 Failsafe - when the SVI2 cannot operate correctly the device goes to the failsafe
position and remains in the failsafe mode until you intervene (indicator red).
