Important information
NOTE
Because the multiple light beam safety device does not have integrated external device
monitoring, this must be implemented in the external control, if required.
Prerequisites
•
Positively guided contactors are used for shutting down the machine.
If the auxiliary contacts of the positively guided contactors are connected to the
external device monitoring, the external device monitoring checks whether the
contactors drop off when the OSSDs are switched off.
4.4.3
Application diagnostic output
The multiple light beam safety device has an application diagnostic output at the sys‐
tem connection and at the connection for a reset/override pushbutton.
Depending on the configuration, the application diagnostic output signals a certain sta‐
tus of the protective device, e.g. if the reset pushbutton must be engaged.
For a signal of the protective device to be displayed, a light can be connected to the
application diagnostic output or the signal can be transmitted to the machine con‐
troller.

4.4.4
Muting lamp
In order to signal muting, you can connect a muting lamp to the system. The muting
lamp signals temporary muting.
NOTE
The muting lamp must be visible from all sides of the hazardous area and visible to the
operator of the system.
Complementary information
If no muting lamp is connected, the temporary muting can also be identified by means
of the signal lamp integrated into the end cap of the active unit.
4.4.5
Muting
Overview
Muting according to IEC 62046 temporarily bypasses the protective action of the multi‐
ple light beam safety device so that material can be transported to or from a machine
or system. As a result, the work process remains uninterrupted.
