5. The jumper for the termination resistor labeled
TERM (see Figure 4) is located at the end of the
protocol dip switch block. Place the jumper over
both pins if the termination resistor is needed, and
over one pin for storage if it is not.
NOTE: If the StarPac unit has a dual communica-
tion port (model SPJD or NT) the termination resis-
tor jumper for the second port is located 90 degrees
clockwise from the jumper described above and
can only be accessed by removing the white pro-
tective plastic shroud from the electronics assem-
bly. Note second port jumper only needs to be set
according to requirements of the second network.
6. When the required communication settings have
been made, replace the white shroud (if removed)
and the large StarPac electronic housing cover.
Changing the Power Failure Setting
On loss of power, the StarPac is factory set to pass the
command signal to the I/P (unless ordered otherwise).
This configuration causes the system to assume a
traditional control valve mode and respond to an external
4 - 20 mA command signal. During loss of power and if
the application warrants, the StarPac system can be
configured to fail using the fail-safe spring(s) inside the
cylinder actuator. This is accomplished by changing
the power failure setting as described below. (Refer to
Figures 2, 6, 7 and 8.)
WARNING: Never remove the StarPac cover in
explosive atmospheres; otherwise potential injury
may result to personnel and equipment.
CAUTION: Properly ground yourself before handling
the StarPac electronics; otherwise the sensitive
components may be damaged.
1. If the StarPac system is currently installed in-line,
make sure that the StarPac system (including valve)
can be taken off line in the current process.
2. Turn off the 24-volt power supply and disconnect
the supply air to the StarPac valve.
3. Remove the large electronic housing cover from
the StarPac unit.
