ObserveThe 4–20 mA input falls into the documented open-wire condition.

CheckUse the barrier fault transparency and verify the field cable, terminal and transmitter loop without bypassing the intrinsic-safety design.

RiskAn invalid safety measurement can demand a safe action or hold the process out of service.

ObserveThe transmitter loop does not establish the expected current.

CheckVerify A/B/C terminal usage for the configured source or sink mode and confirm polarity; the adaptor includes reverse-polarity protection.

RiskIncorrect wiring can delay commissioning and keep the safety channel unavailable.

ObserveThe 4–20 mA value is present but HART communication is not.

CheckConfirm the selected wiring mode supports HART, the CC-UGIA01 connection and the complete loop arrangement.

RiskLoss of device diagnostics can lengthen maintenance while the analog safety signal remains in service.
