If an application configuration has been previously saved to a *.CFG file,
the saved set of parameters can be loaded into the 2301D as a group by
selecting the
Load Application Settings
icon.
To save the configuration to a file in the external computer for backup or
download later into another 2301D when a similar system is being set up, select
the
Save Application Settings
icon. All the tunable values presently set in the
control will be saved to a file and can be loaded into this 2301D control to
reprogram it to the saved values or into another 2301D at a later time.

A**ENGINE & SPEED CONTROL**
01 ENTER RATED SPEED (RPM)
dflt = 900 (0, 4000)
Set to the rated synchronous 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
This value is used to set the 2301D 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.
02 ENTER NUM OF GEAR TEETH
dflt = 60 (8, 500)
This is the number of teeth or holes of the gear or flywheel that the speed sensor
is on. If the gear is on the cam shaft or other drive not turning at the prime mover
speed, the number of teeth needs to be adjusted to compensate. EXAMPLE: If
the gear is rotating at one-half the engine speed enter one-half the number of
actual teeth.
The maximum input frequency that can be measured by the speed
sensing circuit is 25 000 Hz. Therefore to allow for transient
conditions, the (Number of Teeth x Rated rpm) / 60 should be less
than 19 000.
The number of gear teeth is used by the control to convert pulses
from the speed-sensing device to engine rpm. To prevent possible
serious injury from an overspeeding engine, make sure the control is
properly programmed to convert the gear-tooth count into engine
rpm. Improper conversion could cause engine overspeed.
