Glossary
Protective field The protective field secures the hazardous area on a machine or vehicle. As
soon as the safety laser scanner detects an object in the protective field, it
switches the OSSDs to the OFF state and initiates the shutdown of the
machine or stop of the vehicle.
Remission Reflection of luminance. A measure of the remission is the level of remission
that is defined as the ratio of the luminance reflected from a surface in the
measuring direction and the luminance of a matte white surface
(white standard).
Resolution/object resolution The minimum size of an object the protective device acquires and the
manufacturer certifies.
Restart interlock The restart interlock is a protective device. In certain situations, it helps
prevent the machine from automatically restarting. It applies, for example, after
the scanner function has triggered during a dangerous machine state, after a
change to the operating mode or the method of activation of the machine, or
after the change to the start control device on the machine.

Safe state in case of an error If the internal error detection detects an error that prevents the correct
operation of the safety component, the safety component adopts a defined safe
state. The safety component remains in this state until the error has been
rectified. Error cases in which the safety component adopts a safe state
includes:
• Safety-related internal errors
• Invalid input signal conditions
• Supply voltage loss
• Loss of the assured detection capability
SCD software Rockwell Automation® Safety Configuration and Diagnostic software (SCD
software). Software for configuration and diagnostics on the SafeZone Mini
device.
Universal I/O The SafeZone Mini device has two universal I/O connections. These two
connections can be configured as inputs (for example, for stand-by, EDM or
reset) or as outputs (for example, for device error, contamination or second
warning field).
Warning field The warning field is a field with a radius of up to 8 m (26.25 ft) (see Scanning
Range on page 83 ). Using this field, larger areas can be controlled and simple
switching functions (for example, warning functions) triggered. The warning
field is not allowed to be used for tasks that are related to personnel protection.
