Original instructions
Introduction
The GuardShield Micro 400 is an economical three box
(transmitter, receiver and controller) Type 4 safety light curtain
offered in a small profile (15 x 20 mm (0.59 x 0.79 in.)) housing.
The protective heights are offered from 150…1200 mm
(5.9…47.24 in.) in 150 mm (5.9 in.) increments. The compact
housing size allows the GuardShield Micro 400 to be mounted in
areas where standard safety light curtains may not be able to be
mounted due to space constraints. It is also possible to recess the
GuardShield Micro 400 transmitter and receiver into machine
frames.
Micro 400 System
The Micro 400 requires a dedicated controller, either an MSR41
which has ON/OFF functionality or an MSR42 which offers
advanced functionality of fixed and floating blanking, manual
restart and muting. The MSR42 can also be used as a multi
function safety module, allowing the connection of additional
safety light curtains, safety laser scanner — any safety device with
PNP type outputs.
The Micro 400 transmitter and receiver are offered with 8-pin M12
connectors at the end of 500 mm (20 in.) integrated cables. The
patchcords to connect the transmitter and receiver to the
controller are the same part number and are offered in a variety of
lengths. These patchcords are configured on one end with M12
connectors which mate to the integrated pigtail connectors and
RJ45 connectors on the opposite end which plug into to the MSR
41 or MSR42 controllers.
Micro 400 Cascading
The GuardShield Micro 400 is also offered in a “cascadeable”
configuration. GuardShield Cascadeable Micro 400 safety light
curtains allow the interconnection of multiple segments of the
Micro 400 safety light curtain with a common pair of safety
outputs. This cascadeable configurability of the GuardShield
Micro 400 reduces overall system wiring and allows the
GuardShield Micro 400 to be fitted into a variety of applications
where the safety distances for mounting the light curtain may
allow personnel to stand between the light curtain’s sensing field
and the hazard or where multiple-sided guarding is required and
the use of corner mirrors is not possible.
A GuardShield Cascadeable Micro 400 safety light curtain system
is comprised of one or two pair of Cascadeable Micro 400 light
curtains as well as a standard Micro 400 pair as the last segment
pair in the cascaded system.
GuardShield Micro 400 cascaded pairs are offered in both 14 mm
(0.55 in.) and 30 mm (1.18 in.) resolutions in limited protected
heights. It is possible to mix 14 mm (0.55 in.) and 30 mm (1.18 in.)
resolution pairs in a Cascaded Micro 400 system.
Note: The standard GuardShield Micro 400 must always be the
last segment in a Cascaded Micro 400 system
A cascadeable pair of GuardShield Micro 400 light curtains has a
500 mm (20 in.) pigtail with a female M12 quick disconnect on the
bottom of the Micro 400 light curtain and a 500 mm (20 in.) pigtail
with a male M12 quick disconnect attached to the top of the
Micro 400 transmitter and receiver.
The GuardShield Cascadeable Micro 400 system operates as a
single light curtain pair with a common set of OSSDs. Each
segment pair is connected in series making the complete system’s
response time the sum of each segment pair, plus the response
time of the MSR41 or MSR42 and other safety devices in the stop
circuit.
When connecting two cascadeable segments together, the
resultant cable length between segments is 1000 mm (40 in.).
If an additional length between segment pairs is required,
Rockwell offers an M12 to M12 patchcord in 1, 3, and 5 m (3.3, 9.8,
and 16.3 ft) lengths (445L-AC8PC1 or 445L-AC8PC3).
Note: The maximum Cascaded Micro 400 system length can not
exceed 10 m (32.8 ft) as measured between the RJ45
connection at the MSR 41 or MSR 42 Controller to the last
beam in the standard Micro 400, including all cable
lengths. The maximum number of beams in a cascaded
Micro 400 system can not exceed 255 beams.
Micro 400 Washdown Option
The GuardShield Micro 400 is offered with the transmitter and
receiver sealed in clear polycarbonate tubes with an
environmental rating of IP69K. These IP69K Micro 400 light
curtains are factory sealed and are ordered as pairs. They are
offered in a 14 mm (0.55 in.) resolution in protected heights of
150, 300, 600, 900, and 1200 mm (5.9, 11.8, 23.6, 35.4, and 47.2 in.).
The required MSR41 or MSR42 controllers maintain the IP20 rating
and must be mounted in a suitable enclosure.
The Micro 400 IP69K transmitter and receiver are both offered
with
8-pin M12 connectors at the end of 500 mm (20 in.) integrated
cables. The patchcords to connect the transmitter and receiver to
the controller are the same part number and are offered in 1, 2, 3,
5, and 8m (3.3, 6.6, 9.8, 16.4, and 26.2 ft) lengths.
These patchcords are configured on one end with M12
connectors which mate to the integrated pigtail connectors and
RJ45 connectors on the opposite end which plug into to the
MSR42 or MSR41 controller.
Micro 400 Specials
In addition to the standard GuardShield Micro 400 configurations,
the GuardShield Micro 400 is also offered in special configurations
as described in the Appendix.
The GuardShield Micro 400 family of safety light curtains are
general purpose presence sensing devices, designed for use on
hazardous machinery providing point of operation (POC), as well
as, perimeter (PAC) detection.
Important Requirements
The GuardShield Micro 400 requires a dedicated controller. The
MSR41 controller is used for on/off applications and the MSR42
can also be used as a multi-functional safety module, allowing the
connection of additional safety light curtains, safety laser scanner,
or any safety device with two Output Signal Switch Devices
IMPORTANT
These installation instructions are designed to
address the technical personnel of the machine
manufacturer and or the installer of the safety
system regarding the proper mounting,
configuration, electrical installation,
commissioning, operation and maintenance of
the GuardShield Micro 400 safety light curtain.
These installation instructions do not provide
instruction for the operation of machinery to
which the GuardShield Micro 400 safety light
curtain is, or will be, integrated. Only qualified
personnel should install this equipment.
