Fail-safe Timer

Fail-safe Timer determines the time to elapse after the last valid reading before a Fail-
safe state is activated. Fail-safe Material Level determines the level to be reported when
the Fail-safe timer expires. Upon receiving a reliable echo, the loss of echo condition is
aborted, the Service Required icon and error message are cleared, and the reading and
mA output return to the current level.
