Banner AG4 Series Safety Laser Scanner
Field pair switchover control
The FP switchover sequence performed by the control system must agree with the Scanner’s operational settings which are established during
configuration.
NOTE: When switching over between field pairs, keep the first field pair active while activating the second. Do not deactivate one field
pair before activating the second; if no field pairs are active, a lockout will occur.

Reference contour (surface) monitoring
The reference contour (surface) monitoring function prevents unintentional misalignment and deliberate manipulation of the Scanner. If the
protective field contains a reference contour (surface), the Scanner monitors both the PF (for object intrusion) and the reference surface (for
safety integrity). If the distance between the sensor and the reference surfaces change from the original configuration, the sensor will detect this
and will switch the OSSDs to off.
