Figure 42
shows vehicle monitoring for unidirectional travel with a SafeZone
Mini device. The SafeZone Mini device monitors the area in the direction of
travel and switches its OSSDs to the OFF state to stop the vehicle as soon as
there is an object in the protective field.

IMPORTANT • Only use relays/contacts with positively guided contacts. The protection
elements connected in parallel with the relays/contactors are used for
arc-suppression.
• Verify that there is adequate arc-suppression at the relays/contactors.
Consider that arc-suppressors can lengthen the response time.
• The arc-suppressors must be in parallel with the relays/contactors (not
across the contacts).
