  • Last UpdatedAug 06, 2024
  • 1 minute read

AlarmHiLimit sets the maximum measured value shown by the SA_RakeHeightMeter symbol that triggers a Hi limit alarm. The AlarmHILimit value is associated with a Hi limit switch of a SA_RakeHeightMeter symbol.

With the AlarmLoLimit custom property, the symbol shows an acceptable range of vertical movement of a mechanical rake in a vessel. When the measured value of the symbol exceeds the upper or lower limits of vertical travel, an alarm occurs.
