The following should be completed to allow for paralleling the Pow-R-Con to the Woodward 2301A.
1. Wire per standard Pow-R-Con installation procedure with exception of adding the circuit
as shown in figure 1. Consult Woodward 2301A manuals/wiring diagrams for details on
installa tion.
2. The gain (parallel line voltage) of the Pow-R-Con will need to match to that of the 2301A. For
example, typically Barber-Colman systems would see 3 volts on the parallel lines at full load.
3. Verify the voltage on the 2301A and confirm that it is 12.9 VDC to Common. The closer the zener
diode matches the 2301A voltage the less frequency offset when paralleled.
