What can cause external fault in an ATV58 with the P1 communications bridge.

This P1 communications universal serial communications cable is not made or supported by SquareD - Schneider Electric.
With the P1 communications, an external fault can be caused by the P1 signal timing out. Switch #8 on the P1 module enables and disables the fault--with the fault disabled, the unit will just stop and you will not know why so need to leave it enabled. Switches 5, 6, and 7 set the timeout period. With all 3 switches on, the timeout period is 1 minute. Can try increasing the timeout period to 1 minute and see if that helps.
