Response Time T
of the SafeZone Mini Device
S
ATTENTION: The total response time of the SafeZone Mini device must not
be more than 80 ms for access protection.
If a critical response time is exceeded, a person may no longer be detected
under certain circumstances.
In specific cases agreed with the responsible authorities higher response
times may be allowed (for example by increasing the detection time
available by positioning the safety laser scanner at an angle). In this case,
verify that the areas the safety laser scanner cannot see are protected by
additional measures.
The response time T
of the SafeZone Mini device depends on the following:
S
• The basic response time of the SafeZone Mini device.
• The multiple sampling set.
See
OSSD Response Times on page
Hazardous point protection is necessary if the operator must remain near the
dangerous state of the machine. Hand protection is required for hazardous
point protection.
IMPORTANT The SafeZone Mini device must be configured with a resolution of at least
40 mm (1.6 in.)
ATTENTION: Never use the SafeZone Mini device for safety applications in
which finger protection is required.
Due to the finest possible resolution of 30 mm (1.2 in.), the SafeZone Mini
device is not suitable for finger protection.
To help protect the protective device against inadvertent adjustment or
manipulation, you must use the contour of the surroundings as a reference for
the SafeZone Mini device (see
Minimum Distance
For hazardous point protection, a minimum distance must be observed
between protective field and hazardous point. This safety distance helps ensure
that the hazardous point can only be reached after the dangerous state of the
machine has been stopped completely.
ATTENTION: Prevent reaching around or behind the protective field.
Always mount the safety laser scanner such that reaching around and behind
is impossible. Provide suitable additional precautions as necessary.
