Maintenance and Care

Clean Optics Cover

The SafeZone Mini device requires little maintenance. However, the optics 

cover on the safety laser scanner must be cleaned on a regular basis and when it 

becomes contaminated.

• Do not use aggressive cleaning agents.
• Do not use abrasive cleaning agents.
• Static charges cause dust particles to be attracted to the optics cover. You 

can reduce this effect by using the anti-static plastic and the lens cloth.

Optics Cover Cleaning Procedure

1. Use a clean and soft brush to remove dust from the optics cover.
2. Moisten the optics cloth with the anti-static plastic cleaner and wipe off 

the window for light output on the optics cover with the cloth.

ATTENTION: 

Do not make any repairs to the device.

The SafeZone™ Mini device does not contain any repairable components. For 
this reason, do not open the SafeZone Mini device and only replace the parts 

that are described in the following chapters as replaceable.

ATTENTION: 

Switch the entire machine/system off line.

The system could inadvertently start up while you are replacing the optics 

cover. As a matter of principle, always isolate the machine from the power 
supply during all work on the machine and safety laser scanner.
