The 2301D Control Hardware includes:
1 Load Sensor
1
Actuator
Driver
1 MPU Speed Sensor
1 Configurable Analog Output
2 Configurable Analog Inputs
8 Discrete (Switch) Inputs (3 inputs are configurable)
4 Configurable Discrete (Relay Driver) Outputs
The following is an example of the typical hardware needed for a 2301D system
controlling a single prime mover and generator:
A 2301D electronic control
An external 18 to 40 Vdc power source
A speed-sensing device
A proportional actuator to position the fuel-metering device and
Current and potential transformers for measuring the load carried by the
generator
The engine and generator synchronous speed (50 or 60 Hz Generator
Frequency) needs to be within 300 to 3600 rpm. The frequency from the
magnetic pickup must be within the range of 100 to 20 000 Hz at rated speed.
The 2301D speed range needs to be configured using an external computer
during installation.
These 2301D controls operate with an input of 18 to 40 Vdc.
Applications
Because of the configuration software available in the 2301D hardware,
application variations can now be selected using an external computer. Changing
the application to accommodate engine speed range, gear teeth, and selection of
forward or reverse acting actuator is a matter of software setup rather than
changing hardware. See Chapter 4 to enter control set points.
The speed range is factory set for 900 rpm, 900 Hz. Using the wrong
speed configuration could cause an overspeed with resulting
damage to equipment or personal injury or death.
The 2301D Control can be configured for forward- or reverse-acting applications.
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.
External wiring connections for reverse-acting controls are identical
to those for direct-acting controls.
