Mounting and commissioning
Figure 4.1:
Mounting the VARIO B light curtain
Notice!
For the locations of the first and last beams to the profile edge, please refer to table 6.2
"VARIO B dimensions" on page 21.
1.
The transmitter and receiver bars must be aligned with each other with an accuracy of
about 10°.
2.
Do not place any mechanical load on the bars or bend them, etc.
3.
Be careful during horizontal mounting, as liquids may be detected on the front cover
as if they were objects. If they remain there for a long time, they may penetrate the bar
and damage the electronics. Increased risk of soiling.
4.
Protect the cable from being crushed and from exposure to strong electromagnetic
effects.
5.
Strong extraneous light effect (caused for example by strobe lights, direct sunshine)
on the receiver bar should be avoided.
6.
Prevent optical sensors (for example other light curtains, photoelectric sensors) from
affecting each other by positioning them appropriately or blocking them from each
other, etc.
7.
There must be no reflecting surfaces near the light curtain. Otherwise objects may not
be detected due to the reflection.
