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.
The following signals can be output over the application diagnostic output:
•
Reset required
•
Muting status
•
Override required
3.2.6
Muting
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.
The function is configured during commissioning.
The distinction between people and materials is made by 2 signals that are indepen‐
dent of each other. Based on the logical evaluation of these signals, the protective
device is bypassed if a valid muting condition is present. As soon as something other
than material enters the hazardous area, the work process is interrupted.
3.2.7
C1 muting release
The protective device has an internal muting release. The C1 muting release function
can be configured during commissioning and is located at In4 of the system connec‐
tion.
The C1 muting release function is a supplementary signal from an external source that
is only used for muting release and is required for every muting cycle.
3.2.8
Near Field Communication (NFC)
Overview
The active unit of the multiple light beam safety device has an integrated NFC interface
for transmitting diagnostic data of the protective device to an NFC-capable device.
The integrated NFC interface is intended for temporary use.
Diagnostic data
The following diagnostic data can be displayed in an NFC-capable device:
•
Device information and device status, e.g. name, serial number, type code, status
of OSSDs, muting status or quality of alignment
•
Configuration of the device, e.g. whether the restart interlock is activated
•
Fault diagnosis with specification of the error code, error description, diagnostic
LED and troubleshooting
An NFC-capable antenna is integrated behind the front screen of the multiple light
beam safety device for transmitting the data. The area is marked with the NFC-symbol.
