Manual 26641 2301E Digital Control
Woodward 71
Entering the Configure Mode
The Configure Mode can be accessed from either Control Assistant or the 2301E
Service Tool.
The engine must be shut down before performing this operation, as the inputs
and outputs of the control all go to zero.
Configure Menu Descriptions
These menu descriptions are listed in the order from Control Assistant.
A**SPEED CONTROL FUNCTIONS**
01 ENTER RATED SPEED (60 HZ) IN RPM dflt = 900 (0
–4000)
Set to the rated synchronous 60 Hertz rpm of the engine/generator. This will
typically be a value from the following table:
Generator
Poles
60 Hz
Generator
50 Hz
Generator
2 3600 rpm 3000 rpm
4 1800 rpm 1500 rpm
6 1200 rpm 1000 rpm
8 900 rpm 750 rpm
16 450 rpm 375 rpm
This value is used to set the 2301E speed sensor hardware to software
conversion. The rated speed can be varied in Service for testing. If a rated speed
other than values listed here is entered, the calculated generator frequency
shown in **DISPLAY MENU** may not be correct. It is also use to set the range
of the analog meters used in the 2301E Service Tool ToolKit.
02 ENTER RATED SPEED (50 HZ) in RPM
dflt = 750 (0
–4000)
Set to the rated synchronous 50 Hz rpm of the engine/generator (if used). The
2301E has the capability to switch between 60 Hertz operation and 50 Hertz
operation for use with rental generators that require both frequencies. A Discrete
Input can be configured to switch between the 50 and 60 Hertz.
Note: The
engine must be stopped to enable the speed to switch between the two
speeds.
03 USE START SPEED
dflt = FALSE (TRUE, FALSE)
Set to TRUE to enable a tunable Start Speed Reference. Set to FALSE to
disable the Start Speed Reference. This is typically only used on gas engines to
allow speed control below idle speed and to allow acceleration to the Start Fuel
Limiter without over-fueling.
04 ENABLE 5 SLOPE GAIN MAP dflt = FALSE (TRUE, FALSE)
Set to TRUE to permit the use of a 5-gain curve for setting the control gain as a
function of engine load. If “Use 2nd Dynamics” is also set TRUE, the use of a
second 5-gain curve is activated. These two curves each provide 5 tunable gain
settings at 5 tunable load-
dependent breakpoints. If ‘Enable 5 Slope Gain Map’ is
set FALSE only a single gain value is used as the dynamic adjustment.
