Safety field: interrupted
MS: actuated (signal 1)
OSSDs: on
Muting: active
4 Muting object moves into the
danger zone and frees ESPE
and MS.
Safety field: free
MS: free (signal 0)
OSSDs: on
Muting: inactive
DANGER!
• The muting must be triggered by at least two independent signals.
• The use of software-controlled signals (e.g. PLC) is permitted if at least one signal comes
from another source (e.g. from a sensor).
NOTE!
• For easy initial start-up, wenglor offers muting sets (Z2MGxxx), which can be mounted
directly on the ESPE or the safety column Z2SSxxx.
• Further details are available in the standard IEC 62046.
