*—default jumper settings
&—tandem outputs are designed to supply a maximum of 160 mA into two actuators
connected in series.
External wiring connections for a typical 723PLUS control installation are shown
in Figure 1-5. The control wiring connections (Figure 1-4) are explained in the
rest of this chapter.
Shielded Wiring
All shielded cable must be twisted conductor pairs. Do not attempt to tin the
braided shield. All signal lines should be shielded to prevent picking up stray
signals from adjacent equipment. Connect the shields to the nearest chassis
ground. Wire exposed beyond the shield should be as short as possible, not
exceeding 25 mm (1 inch). The other end of the shields must be left open and
insulated from any other conductor. DO NOT run shielded signal wires along with
other wires carrying large currents. See Woodward application note 50532,
Interference Control in Electronic Governing Systems for more information.
Where shielded cable is required, cut the cable to the desired length and prepare
the cable as instructed below.
1. Strip outer insulation from BOTH ENDS, exposing the braided or spiral
wrapped shield. DO NOT CUT THE SHIELD.
2. Using a sharp, pointed tool, carefully spread the strands of the braided
shield.
3. Pull inner conductor(s) out of the shield. If the shield is the braided type,
twist it to prevent fraying.
4. Remove 6 mm (1/4 inch) of insulation from the inner conductors.
Installations with severe electromagnetic interference (EMI) may require
additional shielding precautions. Contact Woodward for more information.
