GuardShield Micro 400 Safety Light Curtains

External Test Signal
In case the risk analysis of the application requires an external test signal
(according to EN 13849-1), refer to the MSR42 Control Unit User
Manual .
Power Supply
The power supply and the evaluation of the protective field of a GuardShield
Micro 400 light curtain can only be conducted through an MSR41 or
MSR42 Series control unit.
Bringing Into Operation
The transmitter and receiver units must be connected to an MSR41 or
MSR42 safety control unit. Then the supply voltage can be connected to
the control unit. After power-up, there is an automatic self-test (duration < 5
s) of all system components.
If the protective field is free and the transmitter and receiver are
correctly aligned, the green LEDs on the GuardShield Micro 400 light
curtains illuminate.
If after a successful power-up the light curtain detects an interruption of
the protection field, the red LEDs on the GuardShield Micro 400 light
curtains illuminate.
Outputs
A GuardShield Micro 400 safety light curtain pair is always connected
to a safety controller. Every connection to a machine controller or a safety
circuit is done through an MSR41 or MSR42 safety controller. Each
controller provides two redundant semiconductor OSSD (Output Signal
Switching Device) safety outputs. One or more MSR45E safety relay
expansion modules can be connected to the MSR41 or MSR42
controller.
Each MSR41 or MSR42 safety controller also provides two status
outputs (Info1 and Info2). These controller outputs can only be
connected to the machine controller for information purposes.
Checklist
Before the initiation of the GuardShield Micro 400 the responsible
person must work through the following checklist.
Check before first initiation or after a changed machine setting (for
example, a rewiring):
1. The power supply is a 24V DC device that must comply to all
applicable standards of the Machinery Directive 2006/42/EC,
and the product standard (IEC61496), for example 1606-XLP-
series. No connection to a conventional power supply.
2. Proper polarity of the power supply at the controller of the
GuardShield Micro 400.
3. The transmitter connection cable is properly connected to the
transmitter, the receiver connection cable is properly connected
to the receiver. All plugs are connected.

ATTENTION: The status outputs (Info1 and Info2) of the MSR41 or
MSR42 safety control units are not safety related. They cannot be used
within the safety circuit of the machine.
Before first powering up or after a changed machine setting, the
responsible person must review the following checklist.
