Arrangement of the muting sensors
b
Place the crossing point of the muting sensors directly on the path of the beams of
the ESPE.
b
If this is not possible, place the crossing point in the direction of the hazardous
area.
Functionality
Once muting sensors A1 and A2 are actuated, muting is active.
Muting remains active until one of the muting sensors becomes clear.

Crossing point for the muting sensors
§
ESPE
The following applies to cross-muting:
•
The signals of the muting sensors are on the extension connection. Alternatively,
the input of a muting signal can be moved to the system connection.
•
Override is active. The number of override statuses is limited to 5.
•
Concurrence monitoring is configured
•
A total muting time is active
•
The muting signal inputs are monitored for cross-circuits
•
Cross muting is ended if one of the muting sensors remains clear for longer than
0.5 s, i.e. the sensor gap monitoring (muting sensor) has been exceeded
Calculating minimum distance
Calculating minimum distance without using a muting connector:
