Message A user-defined field with up to 32 characters. Use this field for any
information. The value appears in many views but can only be
changed from the “Configure Tab” on page 626 tab or with com-
mands sent from the Monitor tab.
Date Use the date field as needed. The preferred format is dd MMM yyyy
(e.g. 14 NOV 2001). The program also accepts dates formatted as dd/
mm/yy (e.g. 14/11/01). Years greater than 70 are assumed to be in
the 1900’s with years 70 or less assumed to be in the 2000’s. The day
precedes the month. Dates as dd/mm/yyyy are also accepted. The
value appears in many views but can only be changed from the“Con-
figure Tab” on page 626 tab or with commands sent from the Moni-
tor tab.
Assembly Number A user-assigned number between 0 and 16,777,215. The value
appears in many views, but can only be changed from the“Configure
Tab” on page 626 or with commands sent from the Monitor tab.
Status The SVI2 tracks many errors and fault conditions. When there is
information on fault codes available in the SVI, this box contains
Additional Status Available.
Signal The value of the input signal expressed as the position it indicates. It
is scaled in percent and is characterized if necessary.
Position The current position of the valve in percent open. 0% is always closed
and 100% is open. Because the travel of a valve may exceed its nom-
inal travel, positions greater than 100% are possible (see“Open Stop
Adjustment” on page 637).
Setpoint When in operating mode, the setpoint is the position indicated by the
input signal (characterized if necessary). In manual mode, it is the
position to which the SVI2 is controlling the valve. Change the man-
ual setpoint by dragging the lower thumb on the position indicator
when the positioner is in Manual mode.
Position Indicator This indicator shows the valve position graphically. The indicator
consists of three parts:
 The upper part contains an indicator that shows the value of
the signal. In Operating mode this is the position setpoint. In
manual mode, this is the position that the valve moves to if
operating mode is selected.
 The center green bar shows the valve position with full left as
closed and full right as open. The numerical valve position is
shown in the center.
