Troubleshooting
Manual Adjustments Disabled
Manual adjustments are disabled when Auto Thresholds are ON. If a manual adjustment is attempted while Auto Thresholds are ON, the
Green display will flash
.
% Minimum Difference after TEACH
The Two-Point and Dynamic TEACH methods will flash a % minimum difference on the displays after a PASS or FAIL.
Value
PASS/FAIL
Description
0-99%
FAIL
The difference of the taught conditions does not meet the required minimum
100-300%
PASS
The difference of the taught conditions just meets/exceeds the required minimum, minor sensing
variables may affect sensing reliability
300-600%
PASS
The difference of the taught conditions sufficiently exceeds the required minimum, minor sensing
variables will not affect sensing reliability
600% +
PASS
The difference of the taught conditions greatly exceeds the required minimum, very stable opera-
tion
% Offset after SET
The Window, Dark, and Light SET methods will flash a % offset on the displays after a PASS or FAIL.
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
Threshold Alert or Threshold Error
Severe contamination/changes in the taught condition can prevent the Auto Thresholds algorithm from optimizing the threshold(s).

The threshold(s) cannot be optimized,
