3.4. Measuring Limits
You can view maximum and minimum values for the sensor values and the process temperature.
In SIMATIC PDM open the menu View – Peak Values, and click on the appropriate tab.
3.4.1. Min. Measured Value1 (default 0.000)
The minimum recorded Sensor value, defined in Sensor units.
3.4.2. Max. Measured Value1
The maximum recorded Sensor value, defined in Sensor units.
3.4.3. Min. Sensor Value (default 0.000) – PROFIBUS PA only
Defines the minimum usable value for the measuring range (physical limit of the sensor) in Sensor units.
3.4.4. Max. Sensor Value (default 100.000) – PROFIBUS PA only
Defines the maximum usable value for the measuring range (physical limit of the sensor) in Sensor units.
3.4.5. Process Temperature Min.
The minimum recorded temperature of the internal electronics.
Open the menu View – Peak Values and select the tab Temperature. If necessary, click on the Reset button.
3.4.6. Process Temperature Max.
The maximum recorded temperature of the internal electronics.
Open the menu View – Peak Values and select the tab Temperature. If necessary, click on the Reset button.
3.5.Detailed Setup
3.5.1.Fail-safe
3.5.1.1.LOE (Loss of Echo) Timer
Amount of time, in minutes, that a Loss of Echo must persist, before the device goes into
Values | Range: 0.00 to 720 (minutes) | |
| ||
Default: 10.000 | ||

3.5.1.2. Restrict LOE (Loss of Echo)
Restricts the rate at which the detected echo is reported when a LOE condition ends, to prevent an immediate jump to the new echo. The rate of restriction is the same as the response (fill/empty) rate.
Parameters
Options
YES (ON) /NO (OFF)
Default: YES
