Configurable muting functions
6.4 Direction detection
I
f Direction detection is activated, a sensor pair must be triggered and cleared again in a
specific sequence. The material can only pass the protective device in one direction. The
order of the sensors within a senor pair is not relevant here. The following table shows the
exact conditions as a function of the number of sensors.
Number of muting sensors Conditions to be met
2 (1 sensor pair) Direction detection is not possible
4 (2 sensor pairs) The sensor pairs must be triggered in the following order
as a function of the direction set:
 sensor pair A before sensor pair B
or
 sensor pair B before sensor pair A
For the muting conditions to be met, the object is only allowed to move through the muting
sensors in the direction and order described.

6.5 Sequence monitoring
If Sequence monitoring is activated, the sensors must be triggered and cleared again in a
specific sequence. The material must completely pass the protective device to ensure that
a muting error does not occur. The direction can be additionally defined by the configura-
tion of the Direction detection. The table shows the exact conditions as a function of the
number of sensors.

For the muting conditions to be met, the object is only allowed to move through the muting
sensors in the direction and order described.
If you activate the additional signal C1, the Direction detection function is activated auto-
matically and cannot be deactivated.
