Test procedure for testing the functionality of a monitoring sensor, monitoring method and monitoring sensor

摘要

The method involves providing an outline test object (12) at an outer side of a protection field (10) that is monitored in a detection area of a monitoring sensor. The position of the outline test object is noted relative to a laser scanner (16) in a spatial dimension. Correct functionality of the monitoring sensor is accepted, when a positive output signal and a negative output signal are specified after a change on a test sequence. Same test object is used as the outline test object and a field test object (14). Independent claims are also included for the following: (1) a monitoring method for monitoring a protection field with a monitoring sensor (2) a monitoring sensor with a scanner.
