Multiple sampling
If multiple sampling is set, an object must be scanned several times before the safety
laser scanner switches its OSSDs to the OFF state. In this way you can reduce the prob‐
ability that insects, welding sparks or other particles result in the shutdown of the sys‐
tem.
If a multiple sampling of 3 is configured, for example, an object must be detected in the
protective field three times in succession before the safety laser scanner switches the
OSSDs to the OFF state.
DANGER
In the case of non-compliance, it is possible that the dangerous state of the machine
may not be stopped or not stopped in a timely manner.
The total response time is increased by the multiple sampling.
b
With a multiple sampling greater than 2, note that a supplement must be added to
the basic response time.
A multiple sampling of 2 is the minimum setting. The multiple sampling can be set to a
value up to 16 using the CDS. The supplement to the basic response time resulting
from this setting is displayed in the CDS.

NOTE
•
Using multiple sampling you can increase the availability of a system.
•
The multiple sampling can be configured in the CDS. A specific multiple sampling
value can be set both for the configured field set and for the simultaneous field
set in each monitoring case.
