3.5.2. Initial pre-start settings
In case the newly installed the speed controller does not control engine speed, be prepared to bellows
sequence.
1) Rated speed
If
RATED SPEED
was not set with a signal generator, set the
RATED SPEED
potentiometer to min-
imum (fully counterclockwise). Set the external speed trim, if used, to mid-position.
2) Stability
Set the
RATED
and
IDLE STABILITY
potentiometers to mid position.
3) Gain
Set the
RATED
and
IDLE GAIN
potentiometers to mid position.
4) Idle speed
If
IDLE SPEED
was not set with a signal generator, set the
IDLE SPEED
potentiometer at maximum
(fully clockwise).
5) Start fuel limit
Set the
START FUEL LIMIT
pot at mid point (maximum is fully clockwise).
6) Close the circuit between terminals 9 and 10 (Close for rated).
3.5.3. Start-up and stable adjustments
Prepare to start the engine. Read this entire chapter before attempting to start the engine. Interrelated
problems can occur, and an understanding of all possibilities is needed before
using a control for the first time.
Caution:
To protect against possible injury, loss of life, and/or property damage when starting the
engine, turbine, or other type of prime mover, be prepared to make an emergency shut down
to protect against runaway or overspeed should the fuel control(s), the driving mechanism(s),
or the control device(s) fail.
1) Adjust for stable operation
Read the following paragraphs before attempting initial engine start up. Dynamics must be quickly
adjusted after initial start up.
2) Immediately after the initial start up, it will be necessary to adjust the governor for stable operation.
Idle and Rated dynamics are completely separate. In most cases the idle speed has been preset at
maximum (fully clockwise) and Rated Speed is selected. In many cases the selection of rated speed
will not indicate a desire for rated dynamics, which will be used when the engine is loaded. Idle
dynamics may be selected and adjusted while rated speed is selected.
