Original instructions
In this application, the SafeZone safety laser scanner
Πonly has a secondary
protective function. The primary safety function that stops the dangerous
movement is provided in the example by a light curtain
, while the
SafeZone safety laser scanner monitors the restarting of the machine.

Hazardous point protection (vertical protection)
The SafeZone safety laser scanner can also be used vertically. Mounting in this
way requires less space on the machine or equipment. Hazardous point
protection is necessary if the operator is near the dangerous state of the
machine. Hand protection must be configured to protect the hazardous
point.

Access protection (vertical protection)
You can also use the SafeZone safety laser scanner vertically for access
protection. Access protection can be used when the access to the machine
can be defined by physical means. With access protection the SafeZone
safety laser scanner detects the entry of a person.

3.3.2 Mobile applications
The SafeZone safety laser scanner can be used both on manually
controlled vehicles, e.g. fork lift trucks, and also on automated guided
vehicles (AGV) or trolleys.
You can use the SafeZone safety laser scanner on vehicles, e.g. to protect
the route of a vehicle through a factory building. If there is a person or an
obstacle in the hazardous area, the SafeZone safety laser scanner ensures
that the vehicle reduces speed and stops if necessary.
