Note!
Behaviour of the AMS 348
i
SSI with laser ON/OFF:
If the laser light spot is positioned on the reflector when the laser diode is switched on, the
AMS 348
i
SSI returns valid measurement values after approx. 330ms.
If the laser light spot is not positioned on the reflector when the laser diode is switched on,
the
AMS 348
i
SSI cannot calculate any distance values. If the laser beam hits the reflector
at a later point in time while switched on, the
AMS 348
i
SSI 200 returns valid measurement
values after the following time span:
t = (measurement distance / 20m) sec.
Example:
Aisle change of a high-bay storage device during which the laser diode is
not switched off while traveling around curves.
Measurement distance 100m –> t = 5sec., measurement distance 200m –
> t = 10sec.
