CAUTION
* When installation, don’t close light-projection/reception window or interrupt area.
* If cover is used, use cover with high transparency.(It is using LED with wavelength 880nm.)
6-2. Relation with floor surface
Spread of sensor beam is 100mm(Reference value) in diameter at 3m. If it installs PBS near floor surface, it
may detect floor surface and may cause malfunction. Install it 60mm or more away. If it is 60mm or less,
install it 1 degree upward.
6-3. Optical axis adjustment
It can meet up/down angle with standard of mechanical axis if detecting object will be 300mm
×
300mm or
more. Make an adjusting mechanism in case of sever adjustment. Dispersion of optical axis against
mechanical axis is follows:-
Dispersion between optical axis and mechanical axis
ENFORCEMENT
* Install firmly not to dislocate optical axis by vibration or impact.
* Make a optical axis adjustment and check some operations before use.
6-4. Influence of mirror surface object far away
In case that mirror surface object such as stainless plate or retro-reflecting sheet is existing at 20m far away, it
may malfunction. In case that, put black tape in reflecting objects or taka an angle of elevation with 5 degrees
or more. If detecting objects is enough size to detect, it can use mirror reflecting avoidance mode.(Refer to
item 3.)
