MPU input:
Used to configure whether magnetic pick-up is used or not.
When parameter is configured as “1”, magnetic pick-up is used for the signal source of the engine
speed. When parameter configured as “0”, the magnetic pick-up is not used, the engine speed is
calculated from the frequency of the generator.
RPM = (Hz * 60) / Pair of Poles. For example: the frequency of generator is 50Hz, when Pair of
Poles configured as 2, RPM = (50*60)/2 = 1500 (RPM).
Fly wheel teeth:
Used to configure there are how many teeth on the fly wheel.
Set pickup now:
If user does not know the fly wheel teeth, to calculate the fly wheel teeth automatically via the
measuring Gen frequency and MPU frequency.
Fly wheel teeth = (f1 * Pair of Poles) / f2, {f1 is MPU frequency, f2 is Gen frequency}.
Operating procedure:
Configure the parameter of “MPU input” as “0”.
Start the Genset, choose “Set pickup now” from the menu after the Genset running normally,
the parameter of “fly wheel teeth” will be automatically calculated at that time.
Configure the parameter of “MPU input” as “1” to finish the setting.
NOTE:
This function is only used for the debug of the controller and Genset.
Please do not implement this function when no RPM signal input.
Pair of Poles:
Used to configure the poles of excitation winding of the alternator.
Use to calculate PRM when the measured speed of controller is from the frequency signal of
generator.
Fuel mode:
Used to configure the type of engine fuel valve (details refer to 4.5).
N.C. type means the fuel channel is closed when fuel can not be used; N.O. type means the fuel
channel is opened when fuel can not be used.
T-sensor type:
Used to configure the type of HET sensor.
Optional kinds of built-in HET sensors in the controller.
