EPORTING
Fail Safe reporting allows the transmitter to change the 4-20mA loop to indicate a failure condition.
This failure may be a sensor failure or a transmitter failure. In any event, the user may select to drive
the loop to 23.0mA, corresponding to the “HI” selection; or 3.6mA, corresponding to the “LO”
selection or to turn the function “OFF”.
