Multi-Beam Safety Light Array 129
Alignment display for SEFB muting
• The signal strength is shown on the segment display for easy alignment of the emitter and receiver.
• This feature is active automatically for 30 s after switch-on.
• During parameters configuration, the display can be shown for a lengthy period of time (up through time-
out) (see section 9.5.8, page 115 ).
• The signal strength should be as high as possible to ensure safe operation and avoid unnecessary process
interruptions.
• The signal strength display is divided into five levels:
Display Meaning Explanation
OSSD
RES
SIG LOW
ERROR
Too weak • Receiver not detecting any emitter beams
• No synchronization possible
• OSSDs are not activated

Alignment must be improved to commission the ESPE.
OSSD
RES
SIG LOW
ERROR
Weak • Signal strength is weak.
• Synchronization complete (SYNC point)
• LED SIG LOW lights up
• OSSDs can be activated
 Improve the alignment to avoid unintentional switching due to
contamination, for example.
OSSD
RES
SIG LOW
ERROR
Medium • Signal strength is adequate with a small reserve for changes
(e.g. contamination, alignment)
• Synchronization complete (SYNC point)
• OSSDs can be activated

If possible, improve the alignment further to achieve higher
process reliability.
OSSD
RES
SIG LOW
ERROR
Good • Signal strength is good with a medium reserve for changes
(e.g. contamination, alignment)
• Synchronization complete (SYNC point)
• OSSDs can be activated

If possible, improve the alignment further to achieve higher
process reliability.
OSSD
RES
SIG LOW
ERROR
Very good • Signal strength is very good
• Synchronization complete (SYNC point)
• OSSDs can be activated
The optimal alignment for high process reliability has been
achieved.
Procedure
1. Installation has been carried out correctly (see section 7, page 83 ).
2. Alignment takes place with a free safety field while monitoring the LEDs and segment display.
3. Loosen the mounting so that the ESPE can only just be moved.
4. Align the emitter and receiver until the highest possible signal strength is shown.
5. Tighten the mounting so that the ESPE can no longer be adjusted. The tightening torques for the different
mounting components must be observed.
