3.4.2 Safety distance
If the level rises to the safety distance SD, the device switches to warning or alarm status.
The size of SD can be set freely in the "Safety distance" (015) function.The "in safety distance"
(016) function defines how the device reacts if the level enters the safety distance.
There are three options:
• Warning: The device outputs an error message but continues measurement.
• Alarm: The device outputs an error message. The output signal assumes the value defined in the
"Output on alarm" (011) function (MAX, MIN, user-specific value or holds the last value). As
soon as the level drops below the safety distance, the device recommences measurement.
• Self holding: The device reacts in the same way as for an alarm. However, the alarm condition
continues after the level drops below the safety distance. The device only recommences
measurement when you cancel the alarm using the "Ackn. alarm" (017) function.
3.4.3 Range
The sensor range is dependent on the measuring conditions. Refer to Technical Information
TI00440F/00/EN for an estimation. The maximum range is shown in the above diagram (valid for
good conditions).
