MiniRanger Plus – INSTRUCTION MANUAL

High Level Switch
The MiniRanger Plus can be programmed as a high level switch. Significant differences
between this and other modes of operation are:
•
the fail-safe function (P070 and P071) is effectively disabled
•
on loss of echo, the measurement immediately defaults to a low value (P006)
•
relay setpoints are measured from the face of the transducer
•
the reading is distance from the face of the transducer to the material
A high level switch application is primarily used to detect a high level condition. As such,
aim the transducer so that it is perpendicular to the material angle of repose at the alarm
level when filling.
Example
A high level switch is required in a corn silo when the material comes within 1 m of the
transducer face. The maximum filling rate is 0.2 m / min.
P112, 1 m
P113, 2 m
