3.4.1.1 Impulses per turn for RPM
Impulses per turn tell the Alba-Engine how many signals the alternator receives before the motor
completes a revolution per minute. 100 impulses per turn is the norm, but this value may vary
slightly, depending on the manufacturer of the alternator.
Figure 18. Detail of the impulses per turn for the calibration of RPM field
To calibrate this parameter having a tachometer installed, start the motor, note the tachometer and
main configtool screen's readings, and change this value while checking the interface's values on
configtool's initial screen to adjust the value accordingly.
3.4.1.2 Send 0 signal when RPM are 0?
You'll notice in some displays that when the motor is stopped while electric supply is still on, the
dials in the digital gauges will go to the maximum value. If this is the case, click on the toggle box to
avoid this behaviour.
