3.58 mA]
1)
Orderable option
LOE Timer (2.5.2.)
Note
When a Loss of Echo occurs Material Level (2.5.1.) determines the material level to be reported
when the Fail-safe timer expires. See Loss of Echo (LOE) (Page 232) for more detail.
Sets the time to elapse since the last valid reading, before the Fail-safe Level is reported.
Values Range: 0.00 to 7200 seconds
Default: 100 s
Fail-Safe mA Value (2.5.3.)
Note
● The default settings are dependent on standard or NAMUR NE 43-compliant device.
● Material Level (2.5.1.) must be set to VALUE to enable the Fail-Safe mA Value to be
reported.
Allows the user to define the mA value to be reported when the Fail-safe timer expires.
