2301A

Load Sharing and Speed Control
Applications
The 2301A Load Sharing and Speed Controls are designed for use in electric generator
systems where multi-unit load sharing is desired. 2301A controls may be used with diesel, gas
or gasoline engines, or steam or gas turbines.
Controls are available:
 For applications requiring droop and/or isochronous speed control
 In forward- or reverse-acting models
 For single or tandem actuator installations
 With accelerating or decelerating ramps
 In several speed ranges
Description
Automatic, adjustable start fuel limiting regulates the maximum fuel setting while the engine is
starting. This helps decrease pollution and engine wear.
Each 2301A control has a self-contained load sensor. Most models provide a
0–200 mA output signal, designed to control Woodward EG, EGB, PB, TM, and 2301
actuators. 0–20 mA output is available for special applications. The output signal is
proportional to the fuel
setting needed to attain the desired speed/load. Position feedback from the actuator is not
required. The 2301A controls are compatible with Woodward SPM-A Synchronizers,
Automatic Generator Loading Controls, Process Import/Export Controls, and Automatic Power
Transfer and Load Controls.
Reliable Control: Simple Adustments
The 2310A Load Sharing and Speed Controls stand up well in harsh environments. Built-in
protection guards against electromagnetic interference/radio frequency interference
(EMI/RFI), humidity, dust and vibration.
The 2301A control contains a single printed circuit board. All potentiometers are accessible
from the front of the chassis. Speed range is set on an internal dip switch, accessible from
inside the cover of the control. Speeds are set according to the speed sensor frequency in
Hertz. External rated speed adjustment can be connected for remote speed change and

manual operation. An optional deceleration ramp is available.
