Overview
The Banner AG4 is an optical, two-dimensional measuring Safety Laser Scanner.
The Scanner emits periodic light pulses via a rotating deflection unit. The light pulses reflect back from objects in the field and are then detected
by the Scanner receiver. The Scanner calculates the precise position of the obstruction from the light travel time and the angle of the deflection
unit when the pulse was emitted. If the obstruction is within the user-defined protective field
(PF)
, the Scanner switches the safety outputs OFF.
Only when the PF is free of obstructions does the Scanner turn the safety outputs back ON, either automatically or following a manual restart
(reset) signal, depending on the operating mode.
