Description Defines the delay in the case of a lost echo.
Input range 0 ... 99999.9 s

Additional information After an echo loss, the device waits for the time specified in this parameter before reacting
as specified in the Output echo lost parameter. This helps to avoid interruptions of the
mesurement by short-term interferences.

Description Definition of the safety distance
Input range –200 to +200 m
Factory setting 0 m
Additional information The safety distance is measured from the reference point of the measurement (lower edge
of the flange or threaded connection). The safety distance can be used to generate a
warning before the level rises into the blocking distance. The In safety distance parameter
defines the rection of the device if the level rises into the safety distance.

Description Defines the behavior if the level rises into the safety distance.
Options • Off (i.e. no reaction)
• Alarm
The device assumes the alarm state and generates the diagnostic event S942 "In safety
distance".
• Warning
The device assumes the warning state and generates the diagnostic event S942 "In safety
distance".
• Self holding
The device assumes the defined alarm state. Additionally, the diagnostic event S942 "In
safety distance" is generated.
If the level drops out of the safety distance, the alarm remains active. The measurement
is continued only after a reset of the self holding via the Acknowledge Alarm
parameter.
