3.3.2 View air gap parameters
Pressing ENTER on an AGM-4/20 channel will display the sensor’s minimum air gap value, and if
programmed, the maximum rotor pole variation over one turn.
The AGM-4/20 acquisition module can be programmed to trigger two types of alarms on air gap
measurements.
1) Air gap value (alarm on minimum air gap)
2) Average air gap variation (alarm on rotor deformation)
3) The information that appears in this section reflects which air gap measurement has been selected with
the cursor: minimum air gap, or rotor deformation.
A base reference measurement is used to calculate the threshold values for each rotor pole. An alarm on rotor
deformation is triggered when the air gap of at least one rotor pole exceeds the threshold value set for that
pole in the reference measurement.
When an alarm is triggered, the bar graph is displayed in high luminosity, and the message Alert or Danger is
displayed on the right of the value.
