Protection against tampering due to shading and glare
The Manipulation prevention option switches the evaluation field if …
•
an object that is smaller than or equal to the blanked object size is in front of the laser
output aperture on the LMS for the configured response time for Manipulation
prevention.
•
the LMS is dazzled for longer than the configured response time for Manipulation
prevention.
Evaluation field
Choose one of the evaluation fields already configured for the evaluation case. Its shape
must match the evaluation strategy (see
section 3.8.2 “Evaluation fields” on page 33
Output
Choose one of the outputs for the evaluation case. If several evaluation cases act on an
output, you must define how the results of the evaluation cases are linked (see
section 3.8.3 “Operator for the evaluation cases on the output” on page 33
Negating the result
By negating the result the field evaluation is signalled in reverse on the output. The output
used is, e.g., then switched if the evaluation field is clear or if the contour is not infringed.
Important
Do not confuse the negation of the result with the setting active high/active low for the
outputs (see
section 3.8.3 “Operator for the evaluation cases on the output” on page 33
