Monitoring Cases
The SafeZone Mini device supports a configuration with monitoring cases.
Each monitoring case includes:
• The input conditions (or control signals) that control the activation of
the monitoring case.
• A field set, including a protective field and warning field or fields.
• The multiple sampling for the field set.
Monitoring cases can be switched with the following input information:
•Static information
Multiple Sampling
If multiple sampling is set, an object must be scanned several times before the
SafeZone Mini device switches its OSSDs to the OFF state. This setting helps
reduce the probability that insects, welding sparks, or other particles result in
the shutdown of the system.
If a multiple sampling of three is configured, for instance, an object must be
detected in the protective field three times in succession before the SafeZone
Mini device switches the OSSDs to the OFF state.
On the SafeZone Mini device, a multiple sampling of two is the minimum
setting. You can set the multiple sampling to up to 16 with the aid of the SCD
software. The supplement to the basic response time that results from your
setting is displayed in the SCD software.
IMPORTANT Use lateral and vertical boundaries of the opening (for example, door frame)
and the floor as reference. In this case, if the position of the SafeZone Mini
device is changed in one or more planes, the distance to the reference
changes and the SafeZone Mini device switches its OSSDs to the OFF state.
ATTENTION: Confirm for each monitoring case that the minimum distance
to the hazardous area is maintained.
See Mounting on page 39
.
You can configure the monitoring cases in the SCD software.
ATTENTION: The total response time increases by the multiple sampling.
With a multiple sampling greater than two, you must add a supplement to
the basic response time (see OSSD Response Times on page 84
).
