Chapter 3 Configurable Functions
Restart of the SafeZone Mini
Device
You can configure the restart behavior of the SafeZone Mini device as follows:
• Without restart interlock
• With restart delay
• With restart interlock
Configuration without Restart Interlock
After the OSSDs on the SafeZone Mini device have been switched to the OFF
state due to an object in the protective field, the OSSDs are re-enabled again
immediately when there is no longer an object in the active protective field.
This configuration is only allowed in the following cases:
• An external restart interlock is realized on the machine controller.
• The protective field cannot be left in the direction of the hazardous
point and the SafeZone Mini device detects people at every point in the
hazardous area.
Restart Delay for Mobile Applications
In mobile applications, you can configure a restart delay from 2…60 seconds on
the SafeZone Mini device. The OSSDs on the SafeZone Mini device change to
the ON state if there is no object in the protective field for the duration given.
This configuration is only allowed if the protective field cannot be left in the
direction of the hazardous point and if a person can be detected at every point
in the hazardous area by the SafeZone Mini device.
You can configure the type of restart in the SCD software.
ATTENTION: It is imperative that you configure the SafeZone Mini device or
the application with restart interlock if the protective field can be left to
approach the hazardous point or if a person cannot be detected by the
SafeZone Mini device at every point in the hazardous area.
During the assessment, pay attention to whether the protective field can be
left in the direction of the hazardous point, to areas that are unprotected due
to the mounting and the unprotected near range of the SafeZone Mini device
(see Methods to Prevent Unprotected Areas on page 53 ).
