Chapter 1. General Information Introduction Special 2301A controls are used to provide load sharing and speed control for installations with engines driving loads isolated through torque converters or for split shaft gas turbines. These systems use magnetic pickups (MPUs) on both the engine or gas compressor side of the unit and the power turbine or driven load (tailshaft) side. -

The N1 gas turbine or compressor side of the unit is then controlled with the 2301A speed control. A 9905-181 speed control is used for the N1 gas turbine and a 9905-182 is used for the N2 power turbine. -

Chapter 2. Installation Introduction This chapter contains general installation instructions for 2301A split shaft or tailshaft controls. Power requirements, environmental precautions, and location considerations are included to determine the best location for the controls. Additional information includes unpacking instructions, electrical connections, and an installation check-out procedure. -
Page 9: Location Considerations
1. Strip outer insulation from both ends, exposing the braided or spiral wrapped shield. Do not cut the shield on the control end. Cut off the shield on the end away from the 2301A control. 2. Use a sharp, pointed tool to carefully spread the strands of the shield. -

Application Note 50536 Installations with severe electromagnetic interference (EMI) may require shielded wire run in conduit, double shielded wire, or other precautions. Contact Woodward or your authorized Distributor for additional information. Figure 2-2. Preparation of Shielded Cables Installation of Controls The two controls used for split shaft or tailshaft governing are normally installed on the same control panel. -

1657-537 or equivalent) to provide about ±5% speed adjustment. Terminals 11 and 12 must be jumpered if the speed trim potentiometer or digital reference unit is not used. The 2301A Speed Control has a jumper installed at the factory which must be removed if a speed-trim device is used. -

2301A Split Shaft Applications Application Note 50536 Before start-up of the prime mover, the speed signal is non-existent, activating the failed-speed-signal circuit. On units with cranking motors, the cranking speed is usually sufficient to provide a speed signal, so an override contact is not needed for starting. -
