Adjustment of the safety light curtain GuardShield Safe 4, GuardShield Safe 2, or GuardShield Type 2 or Bulletin 440L GuardShield:
Step 8
Adjustment of the Light Curtain GuardShield Micro 400
Adjustment of the Muting Sensors and Retroreflectors
Use the integrated laser alignment system (ILAS) for easy 
verification. Touching the symbol 
turns the laser on or off.
The green indicator on the receiver light curtain confirms the 
correct allignment.
The Micro 400 light curtain is best aligned by LED indicators. A 
green LED indicator on either the emitter or receiver light curtain 
confirms the correct alignment.
For the corresponding muting type, check the Muting Types 
section on page 12 for sensor positions.
Tighten the cantilever screw when positioned at the correct 
height and the muting sensors are at the proper distance to 
the light curtain (see the Muting Types section on page 12).
Adjust the reflectors and muting sensors to each other. Check 
the status LEDs on the opto-retroreflective sensor for correct 
operation.
• A pallet should not interrupt the light 
curtain nor the muting sensors. The light 
curtain and the muting sensors should be 
interrupted by the transported goods only.
• For a correct muting sequence, the 
muting sensors must be interrupted from 
the goods with a time difference of >50 ms.
Note: The image shows the RightSight with reflector.
Normally, the muting sensor gets mounted on one 
mounting bar and the reflectors on the other side.
