Mounting and Alignment of Cascading GuardShield
In a cascading system only the LEDs of the segment closest to the
controller are working. LEDs of other segments don’t work.
Micro 400 IP69K
The GuardShield Micro 400 IP69K meets the requirements of
Protection Classes IP65, IP66, IP67, IP68 and IP69K to IEC 60529
standards.
The tubes surrounding the GuardShield Micro 400 have no
influence on either operation range or safety class as per IEC/EN
61496-1.
Mounting kits are provided which attach to the connection and
end module of the tube. The Micro 400 IP69K is supplied with the
two mounting brackets. Do not rotate end or connection cap
(danger of bending the light curtain).
The polycarbonate enclosure must be cleaned regularly and
when dirty.
1. Do not use any powerful cleansing materials.
2. Do not use any abrasive cleansing materials.
3. Due to static charge dust particles remain attached to the
polycarbonate enclosure. You can alleviate this effect by using
an antistatic plastic cleansing agent applied with an antistatic
cloth for cleaning.
4. Clean polycarbonate enclosure as follows:
• Remove dirt on the enclosure using ample quantities of water.
In that way you will avoid scratching the surface.
• Then wipe off with a clean, slightly damp cloth.
• Finally, dry the plastic tube with a clean cloth.
5. Short time (max. 2 min.) with 80°C (176°F) warm water
washable.
After every cleaning process please note the following:
• Remove water residues on the enclosure.
• Wipe the tubes with a clean cloth.
• Check position of transmitter and receiver to ensure that
excessively loose or excessively tight grip or movement to the
back by the safety device is not possible.
• Check safety function of the protective device
The connection plug has to be mounted away from high pressure
water.

Mounting Brackets
The GuardShield Micro 400 is mounted using brackets which
attach to the side of both transmitter and receiver. It may be
necessary to use additional brackets to mount the GuardShield
Micro 400 at a proper safety distance from the machinery hazard.
The backside of the light curtain profile has continuous grooves to
fix the mounting brackets at any position along the light curtain
housing.
IMPORTANT
It helps to align the cascading segments in a
particular order. First connect the last segment
(segment with one connector) closest to the
control unit. Once the LED in the edge is green;
secure mounting brackets of that pair. Next
connect middle segment to the last segment
and connect to the controller. When middle
segment receiver LED is green secure those
brackets. Finally connect the closest segment to
the other segments and connect all together to
the controller.
Only the diagnosis LED of the first segment
displays the protective field status. The LEDs of
other segments stay off.
For aligning a cascaded system, the optical
interface module (see “Accessorie” on page 25)
can be a valuable alignment help.
