GuardShield Micro 400 Safety Light Curtains

4. The OSSD outputs are not connected to +24V DC.
5. The connected switching elements (load) are not connected to 

24V DC.

6. If two or more GuardShield Micro 400 light curtains are to be 

used, make sure that each system is properly installed, to avoid 

optical interference.

Switch on the GuardShield Micro 400 and check its function by 

observing the following: 2 seconds after switching on, the system starts 

to work properly if the protection field is free of obstructions

Troubleshooting

With the help of two LEDs, system conditions and faults of the 

GuardShield Micro 400 systems are indicated.
A red and a green LED are integrated in the end-cap connection module 

of each profile (near the cable), which clearly signals the status of the 

protective field. With the help of the LED display, system conditions and 

faults of the GuardShield Micro 400 systems are indicated.

Figure 18 - Indicators

Table 6 - LED Meanings

The conditions signaled by the LEDs can also be obtained from the 

status outputs of the connected MSR41 or MSR42 control module (see 

MSR41 Safety Module User Manual

 and 

MSR42 Control Module User 

Manual

 of the corresponding control unit).

Continuous red LED: Check the alignment if the LED of the 

GuardShield Micro 400 is continuously red. With the help of the 

optical interface (445L-AF6150), it is possible to display individual 

beam status on a laptop using a USB interface.

Red LED blinking (lockout condition): If the red LED of the 

GuardShield Micro 400 is blinking, the following conditions can cause 

the fault:

1. Inadequate supply voltage to the MSR41 or MSR42 safety 

controller.

2. Transmitter and/or receiver cables not correctly plugged into 

the MSR41 or MSR42 controller.

3. Transmitter and receiver light curtains are connected to the incorrect 

locations in the controller (transmitter plugged into receiver 

connection).

4. Incorrect assembly of cascaded systems (transmitter and receiver 

mixed).

5. Cable connector makes poor contact.
6. Error in the EDM feedback channel at the safety control (only if 

EDM).

7. Short circuit at the OSSD outputs.
8. Foreign light source affects the receiving unit.
9. Blanking configured and wrong light curtain length or 

resolution connected (only if blanking).

Corrective Steps 

1. Examine connections, cables, and plugs of transmitter and 

receiver.

2. Turn the supply voltage off and on again.

With the help of the optical interface, it is possible to display the lock 

out information on a laptop using a USB interface.
If the LED of the safety light curtain is still blinking red, contact 

Rockwell Automation technical support.

Safety Instructions—Maintenance

For safety reasons, all inspection results must be recorded. 
Only persons, who clearly understand the functioning of the 

GuardShield Micro 400 and of the machine, can conduct an inspection.
If the installer, planning engineer and operator are different people, 

make sure that they have sufficient information available to conduct the 

inspection.

IMPORTANT

In cascaded systems only the LED in the first safety light 
curtain illuminates (closest to the safety controller).

ATTENTION: 

Never operate the GuardShield Micro 400 before 

conducting the following inspection. Improper inspection can lead 
to operator injury.
