To prevent this situation arising, you can configure the TAMPER PROTECTION option.
Fig. 23: 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 LMS5xx for the configured response time for Manipulation
prevention.
the LMS5xx 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 3.10.2 “Evaluation fields” on page 43).
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 3.10.3 “Operator for the evaluation cases on the output” on page 43).
Important The related output must be configured for “Application”.
Negating the result
By negating the result the field evaluation output is reversed. 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 3.10.3 “Operator for the evaluation cases on the output” on page 43).
