Updating the firmware cannot hurt. The update can be ordered online. It will either fix the problem or eliminate the EZIO6I as the source of the problem. I believe the EZIO6I I have with v28 firmware is the latest. Bob should double check the wiring that is placing GND on AN1 and AN2 and he should set the Analog Trip points to the values I suggested in earlier posts before ordering the firmware update.
