4.3.5.5
Distributing muting signals
In the standard configuration, the muting signals are at In1 and In2 of the extension
connection. If both muting signals are actuated, muting is active.
However, if a muting signal is to be supplied by the control system, muting signal 1 can
be moved from In1 of the extension connection to In4 of the system connection (system
plug SP2 M12, 8-pin). Once the muting sensor is actuated and the control system sup‐
plies a signal, muting is active. EDM is then not possible on the system and extension
connection.

Sensor gap monitoring
Overview
Sensor gap monitoring allows signals from the muting sensors and the muting end by
ESPE function to be ignored for a defined period without removing a valid muting condi‐
tion.
Sensor gap monitoring (muting sensor)
If a muting sensor briefly becomes clear, i.e. an object gap is detected, the deactivated
muting signal continues to be interpreted as an active signal and muting is maintained.
Muting is only ended if one of the muting sensors is clear for longer than 0.5 s.
The following applies to sensor gap monitoring (muting sensor)
•
Sensor gap monitoring is always active
•
Only one of the muting sensors may be clear (deactivated) briefly. If the 2nd mut‐
ing sensor is also clear, muting is ended.
•
Muting is ended if one of the muting sensors is clear (deactivated) for longer than
0.5 s
Sensor gap monitoring (ESPE)
If the ESPE is becomes clear for a short time, i.e. an object gap is detected, muting is
maintained.
Muting is only ended if the ESPE is clear for longer than 0.5 s.
The following applies to sensor gap monitoring (ESPE):
•
Sensor gap monitoring (ESPE) is active during exit monitoring in combination with
the muting end by ESPE function
•
The ESPE is allowed to be clear for a short time, i.e. to detect a short object gap
•
Muting is ended if the ESPE is clear for longer than 0.5 s
4.3.5.6.2
End of muting by ESPE
Functionality
Using the muting end by ESPE function, exit monitoring ends if the ESPE is clear again
(
!
) and a muting end delay of 0.2 s has expired. This results in a shorter muting time
and greater safety at the same time.
