03 ENTER NUMB OF CYLINDERS dflt = 8 (1.0
–24.0)
This is the number of cylinders the engine has, and is also the number of speed
samples the control will take during each engine revolution. If engine is greater
than 24, set to half the number of cylinders. This is only used with Speed Sensor
Function Type 3.
04 ENTER FAILED SPD SENSE % dflt = 5 (2.0
–50.0)
This should be set to a percentage of rated prime mover speed that will verify a
valid MPU signal exists while the prime mover is starting. (Default is 5% of rated.)
05 MPU ALARM ARM TIME dflt = 10 (0.0
–120.0)
This value is the time delay, in seconds, to wait before latching the MPU failure
alarm and shutdown functions once a valid MPU signal is detected. Opening the
“RUN” contact resets the latch block to prevent MPU failure alarm and shutdown
conditions from occurring with normal stops.
06 ENTER RATED/MAX LOAD (KW)
dflt = 500 (10
–30000)
This is the maximum generator load (in kilowatts).
07 2 CYCLE OR 4 CYCLE? dflt = 1 (1
–2)
This value is the number of revolutions per engine cycle. Set this value to 1 for a
two-cycle engine, and 2 for a four-cycle engine.
08 MAX ENGINE SPEED PERCENT dflt = 120 (30
–400)
This value is the maximum speed percentage that engine will run from the rated
speed percentage. This value is typically used for variable speed applications.
EXAMPLE: With this value raised, the engine speed can be controlled from 900
to 3600 rpm.
09 F=60 HZ OR T=50 HZ SPEED REF dflt = FALSE (TRUE-FALSE)
Select True or False to use the internal 50 Hertz or 60 Hertz speed reference.
10 F=DIS IN SEL OR T=INT 50/60 HZ dflt = TRUE (TRUE-FALSE)
Select False to use a discrete input to select between 50 Hertz or 60 Hertz
operation. This feature could be used for a rental package that has the capability
to switch between 50 Hertz or 60 Hertz. Select True to use the internal 50 Hertz
or 60 Hertz setpoint. This was setup in Configure Menu “A”.
