42
Measurement type
Single ended
Frequency range
10 to 10 kHz
Input voltage range
200 mV to 45 V AC RMS
The Magnetic pick-up (MPU) is an inductive sensor fitted on the engine flywheel for the engine speed sensing. The output of the
MPU is a sine-wave signal.

17, 18. 19 and 20
Type
Stepper motor drive
Max. current
1 A
The actuator outputs are used only for the Rotary actuator, if installed. The Rotary actuator is a 4-wire actuator that is used for
creating an electronic governing application in case of a mechanical fuel system engine. In diesel engines, the Rotary actuator's
shaft output gets mechanically connected to the stop lever or the throttle lever of an in-line or rotary fuel injection pump. In case of
petrol or natural gas engines, the Rotary actuator's shaft output gets connected to the throttle/charge control valve.
It is recommended to follow the connection details of the Rotary actuator connector and SGC 121.
