GuardShield Micro 400 Safety Light Curtains
Mounting Brackets
The GuardShield Micro 400 is mounted using brackets, which attach to
the side of both transmitter and receiver. It can 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.
Further brackets can be obtained as an option, to offer the possibility of
mounting on the side or in the center:
Table 3 - Brackets
Electrical Installation — Connections
The connection of a GuardShield Micro 400 to a machine controller
must occur using an MSR41 or MSR42 Series safety controller module.
Only prefabricated cable (445L-AC8xxx) provided by Rockwell
Automation can be used between the light curtain and controller (see
Table 4
and
Table 5
).
The Micro 400 requires two patchcords, one for the transmitter and one
for the receiver. The M12 8-pin connector is used for connecting to the
light curtain, while the RJ45 connector is plugged to the controller.
M12 to M12 patchcords are used for extending the cable, especially
between cascades of the Micro 400 light curtain.
The connection cables are offered with color coded rings that are
attached to each cable. Remove one color ring from the cable as
necessary. The following color code is defined:
• White – Transmitter (Tx)
• Blue – Receiver (Rx)

curtain are shown in

IMPORTANT
Do not rotate end or connection cap as there’s a danger of
bending the light curtain.
Do not mount brackets on transparent tube. Excessive force can
damage the tube. When using cleaning solutions, consider the
materials that are listed in
Table 2
.
