Connecting GENSYS 2.0 to a Cummins EFC:
Because of the very high sensitivity of Cummins EFC module input, please use the schematic below to
connect your GENSYS 2.0 to the EFC. The resistors must be as close as possible of the speed governor
terminal. This way, GENSYS 2.0 analogue speed output can be set higher (parameter E1076) according to
the resistors used.

PWM 500 Hz (caterpillar/perkins)
K4 output is a 500Hz PWM output signal between 0 and 5V. It is protected against short-circuits between
the output and the battery negative voltage. To activate this PWM output in order to control speed of
Caterpillar or Perkins engines, please check GENSYS 2.0 parameters as shown below.
