Rockwell Automation 1440-VST02-01RA XM-120 Eccentricity Module - Manual (Page 59)

Publication GMSI10-UM010C-EN-P - May 2010
Configuration Parameters 51
Alert Threshold (High)
The threshold value for the alert (alarm) condition.
Note: This parameter is the greater threshold value
when Condition is set to "Inside Range" or "Outside
Range."
Same measurement unit as the
Eccentricity Unit selection for the
specified channel.
Danger Threshold (High) The threshold value for the danger (shutdown)
condition.
Note: This parameter is the greater threshold value
when Condition is set to "Inside Range" or "Outside
Range."
Alert Threshold (Low) The lesser threshold value for the alert (alarm)
condition.
Note: This parameter is not used when Condition is
set to "Greater Than" or "Less Than."
Danger Threshold (Low) The lesser threshold value for the danger (shutdown)
condition.
Note: This parameter is not used when Condition is
set to "Greater Than" or "Less Than."
Hysteresis The amount that the measured value must fall
(below the threshold) before the alarm condition is
cleared. For example, Alert Threshold = 120 and
Hysteresis = 2. The alarm (alert) activates when the
measured value is 120 and will not clear until the
measured value is 118.
Note: The Alert and Danger Thresholds use the
same hysteresis value.
Note: For the Outside Range condition, the
hysteresis value must be less than Alert Threshold
(High) – Alert Threshold (Low).
Speed Range Enable Controls whether the alarm is enabled only when the
measured speed is within a machine speed range.
Enter the machine speed range in Speed Range
High and Speed Range Low.
Note: The tachometer must be
enabled (Pulses Per Revolution set
to 1 or more) and a tachometer signal
must be provided at the tachometer
input when Speed Range Enable is
enabled.
