Introduction
The easYgen-2200 Package P2 has one analog output but a J1939 interface. It is a very easy and cost effective
solution to add an APECS 4500 W/CAN to the system for controlling the frequency.
Please follow the steps described below:
1. Setup of the easYgen controller via ToolKit
In the “CAN interface 2 config.” menu adjust the settings to the values shown in the screenshot. The speed
deviation setting depends on the engine.
2. Setup of the APECS controller
Follow the setup wizard in the ATC tool for entering all engine related values. The analog input needs to be
configured to “CAN input”

3. Setup wiring between easYgen and APECS
Dangerous Voltage!
Some other terminal connections carry voltage with danger to life.
Take care for appropriate safety precautions.
The CAN bus between the units must be wired as follows:
APECS
easYgen
Terminal
CAN-H
CAN-L
J1-7
J1-6
57
58
A termination resistor (120 ohm) must be placed between CAN-H and CAN-L at both ends of the CAN line.
4. Displayed values in easYgen
In the J1939 analog values 1 the easYgen now displays the engine speed (SPN 190) and the throttle position
(SPN 91). The throttle position only shows a percentage value when a potentiometer is wired to the APECS
controller (J2-2; J2-11; J2-12):
