Commissioning
WARNING
No commissioning without a thorough check-up by qualified personnel!
Before you operate a system protected by the safety light curtain C 4000 for the first time,
make sure that the system is first checked and approved by qualified personnel. Please
note the notices in the chapter “On safety” on page 8.
6.1
Display sequence during power-up
After the system is activated, sender and receive go through the power-up cycle. The 7-seg-
ment display indicates the device status during the power-up cycle.
The display values have the following meaning:
6.2
Aligning sender and receiver
After the light curtain has been mounted and connected, sender and receiver must be
aligned in relation to each other. The light beams emitted by the sender must hit the receiv-
er with pin-point accuracy.
Note
If you wish to align a cascaded system, always align the individual systems in the following
sequence: host, guest 1, guest 2.
This is how to align sender and receiver in relation to each other:
WARNING
Secure the plant/system. No dangerous state!
Make sure that the dangerous state of the machine is (and remains) switched off! During
the alignment process, the outputs of the safety light curtain are not allowed to have any
effect on the machine.
>
Loosen the clamping bolts which hold the light curtain in place.
>
Switch on the power supply of the light curtain.
>
Watch the alignment information on the 7-segment display of the receiver (see table 11).
Correct the alignment, until the 7-segment display goes off.
>
Using the clamping bolts, fix the light curtain in place.
