摘要

Creep and rotational movement monitoring in the case of a protection device having normal or enhanced safety, of type designation EBUD-00 (...99) for monitoring various safety aspects related to specific operating conditions of a target system. a) monitoring the stationary state (special operation without movement), with the hazard zone open (protective cover or protective grid), no rotational movement may take place. b) monitoring the stationary state (special operation with movement), with the hazard zone open (protective cover or protective grid), only a limited creeping movement may take place for setting up the target system. c) rotational movement monitoring (normal operation) with the hazard zone closed (protective cover or protective grid), only the permitted, limited rotational movement may take place on the target system. d) the monitoring of the operating states and of the rotational movements must be subject to absolute functional reliability and must always result in disconnection of the drive power in the event of danger (double monitoring in one apparatus).
