Yes Yes Yes Yes
No No No No
Dangerous conditions may persist if selecting "NONE" as the alarm action or "NO" for Loop 1 through Loop 4 Act on Feedback Range Alarms. With "NO" select- ed, the associated loop will hold but the 8390 will continue to operate normally otherwise in the event of an out-of-range transmitter. When applied to control combustible fluids, air, or oxygen, ensure that the action set is appropriate and compatible with the transmitter’s failure mode.
