Measurement The type of measurement and the channel that is
associated with the alarm. Options: Ch1 / Ch2 Overall
Ch1 / Ch2 Tracking
Magnitude *
Ch1 / Ch2 Band *
Speed
Ch1 / Ch2 DC Bias
Important: The tracking and band
measurement selections depend on
which filter measurement (Bandpass
Filter or Tracking Filter) is selected.
See Aeroderivative Measurement
Parameter on page 55.
For example in the XM Serial
Configuration Utility, if you selected
Bandpass Filter for channel 1 and
Tracking Filter for channel 2, then
the measurement selection would
include "Ch1 Band" and "Ch2 Tracking
Magnitude" but not "Ch2 Band" or
"Ch1 Tracking Magnitude."
Condition Controls when the alarm should trigger.
•
Greater than - Triggers the alarm when the
measurement value is greater than or equal to the
Alert and Danger Threshold values.
The Danger Threshold value must be greater than
or equal to the Alert Threshold value for the trigger
to occur.
•
Less than - Triggers the alarm when the
measurement value is less than or equal to the
Alert and Danger Threshold values.
The Danger Threshold value must be less than or
equal to the Alert Threshold value for the trigger to
occur.
•
Inside range - Triggers the alarm when the
measurement value is equal to or inside the range
of the Alert and Danger Threshold values.
The Danger Threshold (High) value must be less
than or equal to the Alert Threshold (High) value
AND the Danger Threshold (Low) value must be
greater than or equal to the Alert Threshold (Low)
value for the trigger to occur.
•
Outside range - Triggers the alarm when the
measurement value is equal to or outside the
range of the Alert and Danger Threshold values.
The Danger Threshold (High) value must be greater
than or equal to the Alert Threshold (High) value,
AND the Danger Threshold (Low) value must be
less than or equal to the Alert Threshold (Low)
value for the trigger to occur.
