2.4.2. LOE Timer
Sets the time to elapse since the last valid reading, before the Fail-safe Material
Level is reported (defined in seconds).
Values
2.4.3. Fail-Safe mA Value
Note: Material Level (2.4.1.) must be set to Value for the Material Level value
to be reported.
Allows the user to define the mA value to be reported when the Fail-safe timer
expires.
Values
2.5. Current Output
Note: Default settings in the parameter tables are indicated with an asterisk (*)
unless explicitly stated.

(OCM model).
Alters the mA output/measurement relationship.
Notes:
• The various options have different reference points.
• Use caution when changing Current Output Function while the device is
connected to a HART network. Current Output Function controls the
primary value and the loop current for the device.
