Flowserve StarPac II Control Valves - Manual (Page 23)

the valve is forced to full open and full closed by driving the
positioner output to its maximum and minimum values.
WARNING: Notify personnel working nearby that the valve will
stroke during this procedure; otherwise, serious injury may
occur.
Configuration Menu
The C ONFIGURE menu is used to set up the variables and scaling for
the analog inputs and outputs, actuator configuration, air supply and
trip limits, units, tagname, communications, LCD controls, and
individual register editing and viewing. Before entering the
C
ALIBRATE menu, the display will indicate that the system will be
taken off-line and ask you to accept that condition. While the
C
ONFIGURE menu is open, the system is in Test mode and will not
respond to control signals. To put the unit back on line, press the
LAST OPTION key until the display asks, “do you want to put the
unit back on line,” and press ACCEPT. When you are in the
C
ALIBRATE menu, a flashing “T” on the right side of the display will
indicate that the unit is in Test mode. Certain functions may cause
valve position to change unexpectedly that could affect the process if
the unit is not properly isolated. The C
ONFIGURE menu is arranged
as shown in Figure 7.

Figure 7: Configuration Menu Tree
Analog Out 1 - This option configures the first analog output
channel. Select a variable from the list using the NEXT and
PREVIOUS function keys on the menu. You will then be asked for a
full scale output value in your selected user units. (This is the
process value that corresponds to 20 mA.) The last step is to enter
the offset or Zero output value in your selected user units. (This is
the process value that corresponds to 4 mA.) Available output
variables are:
Valve Position - Current valve position.
Liquid Flow - Current liquid flow rate.
ISA Up Stream Press - Current compensated upstream line
pressure (defined as two pipe diameters upstream of the valve).
