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).
State Display Description Corrective Action
Threshold Alert Alternates
and
The threshold(s) cannot be optimized,
but the sensor's output will still contin-
ue to function
Cleaning/correcting the sensing environment
and/or a re-teach of the sensor is highly rec-
ommended
Threshold Error The threshold(s) cannot be optimized,
and the sensor's output will stop func-
tioning
Cleaning/correcting the sensing environment
and/or a re-teach of the sensor is required
