2301A 9907-018 Electronic Load Sharing and Speed Control

The Woodward 9907-018 is a model in the 2301A series of load sharing and speed controls. This series is meant for use in multi-unit electrical generator systems. This is a low-voltage (20-40VDC) model in the series. It is forward-acting and uses a single actuator with a current of 0-200mA. This model is CE-marked in compliance with the EU Low Voltage and EMC Directives for European operators. Additionally, the 9907-018 is CSA certified for use in ordinary locations in the US and Canada. This model does not come with the optional deceleration ramp.

Product Description

Summary

The Woodward 9907-018 is a model in the 2301A series of load sharing and speed controls. This series is meant for use in multi-unit electrical generator systems. This is a low-voltage (20-40VDC) model in the series. It is forward-acting and uses a single actuator with a current of 0-200mA. This model is CE-marked in compliance with the EU Low Voltage and EMC Directives for European operators. Additionally, the 9907-018 is CSA certified for use in ordinary locations in the US and Canada. This model does not come with the optional deceleration ramp.

Operational Features

The 9907-018 uses a self-contained load sensor in order to optimize the functions of the unit. This unit can control the load sharing and speed of diesel, gasoline, or gas engines as well as steam or gas turbines. The 0-200mA signal of this unit is designed for use with Woodward EG, PB, EGB, 2301, and TM actuators. All the potentiometers of this unit may be accessed easily from the front of the unit housing.

Additional Specifications

The 9907-018 is a simple unit with a single PCB inside a sheet metal chassis. It has protection from things such as EMI (electromagnetic interference) and RFI (radio frequency interference) in addition to physical hazards such as dust, humidity, and vibrations. The unit is meant to be kept in temperature conditions between -40 and 85 degrees Celsius during use.

2301A 9907-018 Electronic Load Sharing and Speed Control

These controls are available for forward- or reverse-acting applications, and for use with either single or tandem actuators. Models for three different actuator current ranges are available, as well as a high-voltage model (90 to 150 Vdc or 88 to 132 Vac, 45 to 440 Hz), and a low-voltage model (20 to 40 Vdc). The high voltage model is identified as such on the front; the low voltage model is not.

In reverse-acting systems, the actuator calls for more fuel when the actuator voltage decreases. Complete loss of voltage to the actuator will drive the actuator to full fuel. This allows a backup mechanical ballhead governor to take control rather than shut down the prime mover as would a direct-acting system.

An optional deceleration ramp is also offered. When this option is present, the time to ramp from rated speed to idle speed is approximately 20 seconds. If this option is not present, this happens instantly.

Tables 1-1 and 1-2 show part numbers and features of all 9905/9907 series 2301A load sharing and speed controls.
