Flowserve StarPac II Control Valves - Manual (Page 31)

recommended that you use the StarTalk for windows software to
reload your system information from the factory supplied disk.
Data Logger - This option sets the interval between data points on
the internal data logger. NOTE: You must use StarTalk software to
download a data logger file from the StarPac II.
Time Set - This option sets the internal StarPac II clock. The
internal clock is battery driven and keeps time whether the unit is
powered or not. Use the F1 and F2 function keys to select the field
to edit. Note that the time is in the 24 hour format and the date is the
mm/dd/yy format.
Pulse Relay Output - Configures the Pulse Out channel on the
StarPac II system for the process variable and scaling. First you
must select a variable from the list using the Next and Previous
function keys on the menu. Next you are asked for a full scale
output value in your selected user units. (This is the process value
that corresponds to the maximum frequency.) 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 0 Hz). Available output
variables are the following:
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).
ISA Dn Stream Press - Current compensated downstream line
pressure (defined as six pipe diameters downstream of the
valve).
ISA Delta Pressure - Current differential pressure using the
pressure definitions above.
Process Temperature - Current process temperature.
Gas Flow - Current gaseous flow rate.
Auxiliary 4-20 Input - Re-transmits the 4-20 mA signal from
analog in No. 2.
Register Number - Allows the selection of any internal register
value as an output.
Changing or Viewing the Fluid
Specification
The StarPac II system must be configured for the exact fluid that you
have in your process. The factory configures the system with fluid
data for your system using the information supplied with the order.
Verify that the fluid data is correct for your process. The StarPac
system requires the following fluid data for accurate flow calculation:
Antoine’s A coefficient register 70329
Antoine’s B coefficient register 70331
Antoine’s C coefficient register 70333
Critical Pressure in psia register 70341
Critical Temperature in ºR register 70343
