fields is in Bold type. Press the F key under this field to bring up the
choices shown on the bottom row. If you see the word ‘Next,’ then
push the F4 button to bring up the continuation of that row. To move

Initial Startup
The StarPac II system is designed to interface with a variety of DCS
systems using analog, discrete, and digital communications.
Because of the processing power of the StarPac II system, a
separate 24 VDC power connection is required and connected to
terminals 16 (-) and 17 (+). This power supply should have a
minimum current capacity of 300 mA.
Before powering up the unit - Read the section “Setting the
System Jumpers” and set them according to the instructions and
particular application.
Powering up the unit on the bench - When the unit is first powered
up, the display will show the version number of the firmware for two
seconds before beginning operation. The StarPac II system sensors
are calibrated at the factory and the fluid data is entered as specified
on the order. However, due to the differing nature of installations,
the units and ranges of the analog and discrete I/O are not
configured at the factory.
The suggested process for setting up a new system on the bench is:
1. In the C ONFIGURE menu, select the engineering units you will
be using.
2. If you will be using analog I/O signals, use the C ONFIGURE
menu to set up the analog channels to indicate the proper
process variables and ranges you will be using. Note that
the StarPac II system treats gas flow and liquid flow as
different variables and they must each be specified correctly.
3. Connect the instrument air supply (40-150 psi) to the ¼-inch
NPT air supply port located on the back of the unit.
4. Use the S TATUS menu and set the Row Two variable to
“valve position.”
5. Use the T UNE menu to put the unit in to Manual mode with a
digital command.
6. Using the “Command %” option in the T UNE menu, enter a 0
percent command and verify that the position follows to
within 0.5 percent.
Note: Command is a term with two meanings. For a
traditional control valve, the command is the signal a
controller sends to the I/P. position the stem. For the StarPac
II, this meaning refers to the signal sent to the positioning
module. When the StarPac II is in Manual mode, Command
also refers to the signal sent to the StarPac II via analog input
No. 1, a digital Modbus channel, or the front keypad. These
commands may differ due to the internal stroke calibration
and an inverted signal for air to close valves.
