Banner AG4 Series Safety Laser Scanner
9.
Using the configuration software (
AG4soft
), select the hand or arm protection presetting.
NOTE:
The maximum PF range limits are automatically set as a result of the field resolution (30mm or 40mm) requirements.
10.
Specify the PF boundaries and define the reference surfaces if appropriate
(see PF and Reference surfaces section below)
11.
Under controlled conditions where no personnel are exposed to the hazard, test the Scanner along and within these boundary.
Important:
Verify that the Scanner OSSDs switch off whenever the protective field is entered.
Check to be sure there are no unprotected access routes to the hazard.
See
Commissioning and Check out
procedures in Section 7
12.
Measure from the hazard point to the protective field boundary to be sure that the proper separation distance has been established.
13.
Connect the AG4 OSSDs to the machine interface and, under controlled conditions where no personnel are exposed to the hazard, test
the Scanner along and within the boundaries to ensure that the dangerous motion will stop and not start up while an object is in the
protective field.
WARNING . . . AG4 RESPONSE TIME ADJUSTMENTS
Never increase the Scanner’s 80 ms response time for vertically positioned protective fields such as work cell access
(Entry/Exit), passageway or perimeter guarding applications where a person could move quickly through the protective field
without being detected.
Failure to follow this recommendation could result in serious bodily injury or death.

PF and reference surface
With a vertical PF at least two sides of the PF contour must be defined as reference contour or surface in accordance with IEC/EN 61496-3. The
reference surface borders the protective field and the special relationship between the reference surface and the field boundary is continuously
monitored. If the distance between the Scanner to the reference surface change, the safety outputs will switched off. This reference surface
monitoring function is used to improve the safety integrity level where reference surfaces are available.
