Gen3 - Hardware - Pressure Sensor related Incorrect Weight readings
Incorrectly terminated pressure sensors create incorrect and nonsensical Gen 3 Display readings.
The Gen3 system uses inclinometer sensors to monitor chassis & boom angle, photoelectric devices to monitor boom extension and pressure sensors to monitor the hydraulics of the boom. This incoming raw sensor data is then used to calculate machine operating parameters, onscreen weight display and machine cutouts. The Gen3 system uses four strategically mounted pressure sensors to monitor boom movements and lifted weights. Each pressure sensor monitors a specific component of the machine's shifting hydraulics. All raw data from these pressure sensors is then used by the Gen3 CSDM (Display), to calculate and then in real time, display the lifted weight.
During a fresh Gen3 install or when machine hydraulics are serviced, occasionally installers will accidentally interchange the pressure sensor connections on the Gen3 CPIM module, causing incorrect onscreen load weight readings.
In order for the Gen3 system to function correctly, the Main Head sensor MUST be plugged into the Main Head port on the CPIM and the Main Rod sensor MUST be plugged into the Main Rod port on the CPIM. If these are swapped, the Gen3 system will not display load weights correctly. The same applies to the Compensation Head and Rod sensors. The Compensation Head sensor must be plugged into the Compensation Head port on the CPIM and the Compensation Rod sensor MUST be plugged into the Compensation Rod port on the CPIM.

Please check all sensor connections are plugged into the correct ports.
