connected, the pickup will be
used to calculate the engine
speed; otherwise the speed will
be estimated based on the
frequency of the output voltage.
Note: if you connect a pickup, it
must also be calibrated. See

4.2.1 Magnetic pickup calibration
If the generator has a magnetic pickup installed, the output can be connected to the VGM,
enabling the engine speed to be measured. The pickup generates a pulse every time a flywheel
tooth passes it. If the number of teeth is known, the engine speed can be calculated based on the
frequency of the pulses received from the pickup. Although the number of teeth can be entered
manually, it is much simpler to allow the VGM to determine this using the magnetic pickup
calibration procedure. The calibration procedure is as follows:
Step 1) Connect up the generator controller (see chapter 2 - Installation of your VGM).
Step 2) Set the “Gen frequency” property to the correct value.
Step 3) Set the “Magnetic pickup” property to “connected”.
Step 4) Manually start the generator, and run it with a steady load (or no load).
