Response to overload and over range detection
The graphic below describes the behavior of the monitoring device in response to over range and
overload situations:
Response to over range detection
When the relative shaft vibration (dynamic AC value) is in over range:
•
the corresponding analog output shows 20.5 mA.
When the static sensor position (DC-GAP) is in over range:
•
The corresponding analog output shows either 3.8 mA (below
– sensor moving towards the shaft)
or
•
The corresponding analog output shows 20.5 mA (above
– sensor moving away from the shaft)
