The incorrect sensing connection protection (SENSE) is also activated when the voltage drop in the load cable exceeds the compensation voltage ensured by the remote sensing function.
The remote sensing function in PAT-T series compensates 0.6 V at the one side of the cable.
Check how much voltage drops in the load cable.
If it exceeds 0.6 V, increase the number of the load cables or change to the load cable with the larger cross-sectional area.
