Muting end point (productive version)
The protected field monitors the danger zone between upper tool and workpiece up to a re-
maining gap. The remaining gap begins when the tip of the upper tool reaches the muting
end point. So the muting end point corresponds to the end of dynamic muting (see
Dynamic
muting (productive version) [
32]
) and to the start of the control system's muting of the
safety function.
In practice the PSENvip must mute the protected field shortly before reaching the muting
end point in order to prevent the press stroke from stopping.
On the productive version there are two options for defining the muting end point:
}
Using the fixed muting end point
The productive version of PSENvip operates as standard with the fixed muting end point
of 4 mm. If the fixed muting end point is to be used, the user has nothing further to do.
Please note: The protective function of the PSENvip may be muted from a remaining gap
of 6 mm, depending on the regulations of the country in which the PSENvip is operated
and the requirements of the appropriate regulatory body.
}
Using a configured muting end point
The productive version of PSENvip supports a configurable muting end point. A value in
the range 4 … 1.6 mm may be configured as the muting end point. For the configuration
please refer to the operating manual for the special module PSSu K F FAU P – under
"Communication with the safety system".
WARNING!
Loss of safety function due to incomplete or faulty download of the
configured muting end point
A muting end point less than 4mm must be configured and downloaded to
the PSSU K F FAU P if required by the safety assessment for the overall
application or by the regulations of the country in which the PSENvip is be-
ing used. Depending on the application, serious injury or death may result if
the safety system enables the downward movement in rapid traverse mode
before the download of the configured muting end point is complete.
Via the safety system's user program, make sure that downward movement
in rapid traverse mode is not enabled until communication between the
safety system and PSSU K F FAU P has been completed without error.
