4.4.5 Magnetic pick-up
A magnetic speed sensor (pickup) is the most common method of engine speed measurement. To use this
method, mount the pickup opposite to the engine flywheel, connect the cable to the controller as shown on the
picture below and adjust the setpoint Gear Teeth (page 160) according to the number of teeth on the flywheel.
For the details about the pick-up input parameters see Technical data on page 145
IMPORTANT: To ensure proper function use a shielded cable.
Be aware of interference signal from Speed governor when one speed pick-up is used
If engine will not start:
Check ground connection from pick-up to controllers, eventually disconnect ground connection to one of
them
Use galvanically separate RPM input using separation transformer RPM-ISO (1:1)
Note: In some cases the controller will measure a RPM value even though the gen-set is not running: RPM is
measured from the generator voltage (Gear Teeth = 0). Controller is measuring some voltage value on input
terminals due to open fusing. If RPM > 0 the controller will be put into a Not ready state and the engine will not
be allowed to start.
