"reset"
Is used to reset the index pointers for the external temperature sensor.
Selection:
• keep (default)
The index pointers are not reset.
• delete
Both index pointers are reset to the current temperature.
• reset min.
"min. value" is reset to the current temperature.
"max. value" keeps its value.
• reset max.
"max. value" is reset to the current temperature.
"min. value" keeps its value.
11.2.3 "external temperature sensor"
(error handling)
"error handling"
Determines the reaction of the Prosonic S in the case of a failure of the external temperature sensor.
Selection:
• alarm (default)
An error message is generated.
The output signal assumes a defined value ("output on alarm" in the "safety settings" menu).
• warning
An error message is generated, but the measurement continues.
The signal evaluation algorithm uses the temperature as defined in "value at warning".
"value at warning"
Defines the temperature which is used for signal evaluation in the case of a failure of the
temperature sensor (only valid for "error handling" = "warning").
