Low Alarm:
This enables or disables the RPM low alarm.
Low Alarm:
Enter the RPM threshold for when the low alarm must be activated. Any RPM value below this value will activate the
alarm.
Pulses/Rev:
Enter the number of pulses per RPM. For engines with an uneven number of cylinders like three cylinder four stroke
engines you can enter values containing fractions (usually 1.5 in this example). Most four stroke engines would generate
one pulse for every two revolutions per cylinder. A four cylinder automotive four stroke engine would thus generate 2
pulses per revolution. A typical Rotax DCDI two stroke engine would generate 6 pulses per revolution. The well known
Rotax 912/914 engine generates one pulse per revolution.
Increment:
Select the step size between successive RPM values eg. if the RPM value is 4003 RPM and the “RPM INCREMENT” is 5
then the actual value shown is 4005 RPM.
Label:
Enter a label to suit your channel so you can identify it easily.
Data:
Select the data source of the RPM signals. Options include internal (using the internal electronics within the EMS-2) or
from an optional external RDAC unit.
RDAC Address:
Select the CAN address of the RDAC unit.
