Muting variants
4.3.6.2.1
Cross muting
Overview
For muting using a crossed arrangement of the muting sensors, material can move
either from left to right or from right to left, i.e., material flow is possible in both
directions.
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.
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.
Principle of operation
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:
•
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 ends if one of the two muting sensors has become clear and the
sensor gap monitoring of 0.5 s has passed
Calculating minimum distance
