Product Description

The 8272-611 control from the Woodward inc 2301A series is used as a split shaft or tailshaft control. The desired rpm of the engine and tailshaft is virtually the same, although it is uncommon for the gears that are being used to recognize identical speeds. Using only the speed of remote load presents a risk of Overspeed by the prime mover, and can cause issues when starting the control. The 8272-611 controls output from 20 to 160 mA. The fuel control on the turbine must obtain this operating signal. 

The 8272-611 administers control in a droop or isochronous mode. Drop mode is used for the parallel operation of two or more prime movers and isochronous mode is used for base loading. Standard hardware for the 2301A system is 2301A controls, external 20-40 Vdc power for low voltage models or for high voltage models, 90-150 Vdc or 88-132 Vac, and current and potential transformers if searching for identification of models; high voltage models are on the front and low voltage are not. Loss of voltage to the actuator will drive the part to full fuel, which allows for backup to take control of the prime mover rather than shutting it down. 

Location of installation of the control is important, when doing so take into account space for servicing and repair, adequate ventilation, and protection from high-current devices. Absolutely no relay is required between the control and load-sharing line bus, use shielded cables when connecting the control lines. Do not apply power to the control before the control is completely connected or it may cause damage to the control.

The 8272-611 control from Woodward's 2301A Load Sharing and Speed Control, is covered under AX Control Inc's three-year warranty.
