Check loop polarity and resistance before applying output power, then compare commanded current, measured current and module readback at controlled test points for each serviced channel.
Important Notice: Match both CC-PAOX01 and 51405039-275, the installed IOTA type, channel ranges and fail options before disturbing field loops.
The Official Technical Reference Excerpt covers channel count, current-output limits, FAILOPT behavior, accuracy and IOTA choices. The Installation & Commissioning Guide organizes isolation, loop reconnection, current testing and controlled return to service.
