• Ensure that the block valves in the process line
around the unit are closed and the process is
diverted around the unit.

3. Turn on the 24 VDC power to the unit, and verify that
it has been correctly wired by checking the following:
• 24 VDC power is at least 300 mA and between 18.0
and 64.0 VDC
• Polarity is correct
• Local display is on; if not, check the power supply.
4. Close the front cover on the housing of the unit.
To connect the wiring to the StarPac II / Logix 2000 unit,
refer to Figures 1 and 4, and Table I, then proceed as
follows.
1. Open the lower door on the front of the housing.
WARNING: Do not open the electronic housing
covers in flammable atmospheres; otherwise,
possible injury to personnel or equipment may
occur.
2. Connect the required wires to the terminal interface
block and computer as described in Figure 4 and
Table I. (The system must have 24 VDC power for
operation.)
NOTE: The StarPac II / Logix 2000 unit remembers
the operating mode setting (automatic or manual)
from the last time the unit had power. When power
to the system is turned on again, the unit will resume
operation in the previous mode.
Normally the unit arrives from the factory set in the
manual analog operating mode. This means a
command signal will position the valve the same as
a traditional control valve, providing a plug position
proportional to the 4 - 20 mA signal.
To avoid upsetting the process because of improper
operating mode selection:
• Ensure that the system arrived from factory with
the proper operating mode setting in the shop prior
to installation by connecting air supply and com-
mand signal, then turning on the power and looking
at the mode value on the local display, or;
• Set the proper operating mode for the particular
application in the shop prior to installation by
selecting the desired operating mode from the
local interface or in the Tuning/Tune screen of the
StarTalk software, or;
