About the 9905-148

The control 9905-148 is forward acting with a supply voltage of 10-40 Vdc and needs an actuator current of 0-200 mA. The Vdc of the control indicates that this control is a low-voltage model. This specific model is offered at AX Control Inc where we buy, sell, repair, and refurbish this model. Additionally, we offer a one to three-year warranty on the control. 

For the initial start-up of the prime mover be sure that the close for rated contact is closed, to set the control to isochronous operation close the droop contact on the control; note that this sequence should only be taken when initially starting the prime mover if wishing to start the prime mover at an idle rate make sure that the close for rated contact is open. Once these steps have been completed power can be input to the control. 

If using the minimum fuel contact terminal on the control for this low-voltage model the connection should be made at terminals two and three, if the minimum fuel contact is not used then the terminals that are not being used it is required terminals are permanently jumpered.

Control unit 9905-148 is from the 2301A series of Load Sharing and Speed control by Woodward INC. Take care when operating the control and prime mover together, be sure that there is an emergency shutdown system in place in case the engine, turbine, or other prime mover attached to the control over speeds or overheats, if there is no emergency shutdown maneuver in place death, personal injury or runaway of the prime mover could occur.
