factory sealed in polycarbonate enclosures.
The GuardShield Micro 400 require a controller to operate in
conjunction with one of the following safety controllers
• MSR41 ON/OFF functionality
• MSR42 multi-function module
Proper Use
The GuardShield Micro 400 safety light curtain must be used only
as defined in the “Range of Uses of the Device.” It must be used
only by qualified personnel and only on the machine where it has
been installed and initialized by qualified personnel.
If the device is used for any other purposes or modified in any
way, warranty claims against Allen-Bradley/Guardmaster shall
become null and void.
General Protective Notes and Protective Measures
The national/international rules and regulations apply to the
installation, use and periodic technical inspections of the safety
light curtain, in particular:
• Machine Directive 2006/42/EC
• Low Voltage Directive 2006/95/EC
• Use of Work Directive (2009/104/EC)
• The work safety regulations/safety rules
• Other relevant health and safety regulations
Manufacturers and users of the machine with which the safety
light curtain is used are responsible for obtaining and observing
all applicable safety regulations and rules.
• The notices, in particular the test regulations of these
installation instructions (e.g. on use, mounting, installation or
integration into the existing machine controller) must be
observed.
• The tests must be carried out by specialist personnel or
specially qualified and authorized personnel and must be
recorded and documented to ensure that the tests can be
reconstructed and retraced at any time.
• The installation instructions must be made available to the
user of the machine where the GuardShield Micro 400 safety
light curtain is installed. The machine operator is to be
instructed in the use of the device by specialist personnel and
must be instructed to read the installation instructions.
Product Description
This section provides information on the special features and
properties of the safety light curtain. It describes the structure
and functions of the unit, in particular the different operating
modes.
Please read this section before mounting, installing and
commissioning the unit.
Special Features
• Slim design 15 x 20 mm (0.59 x 0.79 in.)
• Built in diagnostic LEDs
• HW configurable with MSR41
• HW and SW configurable with MSR42
• M12 connector on 20 inch pigtails
• Maintenance free and cost effective
Principle of Operation
The GuardShield Micro 400 safety light curtain consists of a non-
matched pair of optic units, i.e., transmitter and receiver with the
same protected height and resolution. The controller
functionality of the Micro 400 light curtains are through a
separate control module.
• MSR41 ON/OFF functionality
• MSR42 multi-function module
The maximum distance between transmitter and receiver is
referred to as the protective field width or range. The protective
field height is the distance between the first and last beam in the
device.
The transmitter emits sequential pulses of infrared light which are
received by the GuardShield Micro 400 receiver and processed by
the connected controller. The synchronization of the timing of the
emission and reception of infrared light pulses is accomplished by
the connected MSR controller.
The connected controller has safety outputs [Output Signal
Switching Devices (OSSDs)] and nonsafety auxiliary outputs.
When the GuardShield Micro 400 transmitter and receiver are
properly connected and aligned, the OSSDs of the connected
controller are current sourcing +24V DC. Interruption of the
sensing field causes the controller to switch the sourced current
OFF (0V DC).
