WOODWARD 9907-028 Switch governor

The WOODWARD 9907-028 can be used to parallel an isolated bus to another bus, as shown in Figure 2-2. Up to seven generators operating in parallel on an isolated bus may be synchronized to another bus. In this case, the synchronizer's low impedance output to the load sharing and speed control's SPM input is tied to each control (through a resistor if the control is not normally connected to the low impedance output). The resistor value is determined by the kind of control used (refer to the table below). A resistor with a wattage rating between 1/4 and 1 watt may be used. The resistor should be installed in the line from the synchronizer output terminal designated ± (terminals 20, 22, or 24 depending on type of control) and located close to the control to reduce noise pickup.

Although the 9907-028 can be switched to parallel generators in sequence to a bus, Woodward Governor Company does not recommend this option.
