10. Q and A
Q When PBS receives strong light (specification environment is exceeded) such as the afternoon sun directly,
how does output operate?
A To the direction where a strong disturbance light hit, output executes as no obstacle. About other detection,
it operates normally. (It is hardly affected in comparing with our PB6 and PB8).
Q How about mutual interference between PBS's?
A Basically, it interferes but it isn't affected by interfering light from except for the direction which interfering
light enters because it judges with 1.8 degrees/1 scanning respectively. See item 8 about mutual nterference.
Q Do you have any countermeasures to prevent interference
A Take a installation angle to PBS and see about "Mutual interference".
Q How about the influence to the other sensors?
A Since this device modulates emission wave length(
λ
=880nm) with 8/7.5MHz, there are any a possibilities
to affect to any device with similar modulation system. If you use it with such device at the same time,
check beforehand.
