SET Result
% Offset Meaning
PASS (with % Offset)
Displays the % offset used for the SET method
FAIL (with % Offset)
Displays the minimum required % offset necessary to PASS the SET method
FAIL (without % Offset)
Presented condition cannot be used for the SET method
Health Mode Alarm
The Health Mode Alarm alerts you when preventative maintenance becomes necessary to ensure reliable sensing. The
Health Mode output 2 is Active when the system is OK and operating normally. Health Mode output 2 becomes Inactive
when the system is in a marginal state because of contamination. The system still operates normally and can detect small
objects, but is nearing the alarm state. When the system is completely contaminated and unable to ensure reliable
sensing, the system goes into the alarm state. In the alarm state, the discrete output 1 is forced to the blocked state and
can no longer be used to detect small objects.
•
Threshold Alert
displays when Health Mode output 2 is inactive because of contamination. The
system operates normally but is nearing the alarm state.
•
Threshold Error
displays when discrete output 1 is forced to the blocked state and can no longer be
used to detect small objects.
The sensor may enter Health Mode Alarm for any of these reasons:
1. When first powered up; the fiber optic array may already be contaminated
2. If the Window SET procedure fails, indicating the fiber optic array is contaminated and the sensor could not set a
valid clear-state light level for reliable detection
3. If the fiber optic array is contaminated enough that the auto compensation tracking algorithm cannot sufficiently
adjust the thresholds to ensure reliable detection
4. If the fiber optic array is blocked for more than 2 seconds
Return the system to normal operation by cleaning the fiber optic array and performing a Window SET to reset the clear-
