First a 25/64” hole has to be drilled in the position where the OptoSense sensor
shall be located.
Then the controller will be positioned below the table top in a way that the
centering stud of the endcap on the motor connection side of the controller will
reach into the 25/64” hole. (see sketch).
Now the controller is positioned in reference to the table top. The controller can
now be screwed to the bottom of the table top by two screws one on each fixing
point at the ends of the controller. A suitable fastener size is #8 wood screw. The
length is determined by the thickness of the table top, however it should be
minimum ½ inch. When using other size screws, it is important, that the shaft of
the screw is not wider than the slot in the fixing point and that the head is not
bigger in diameter then 3/8 inch. The torque is determined by the material of the
table top, it is important, that the fixing points at the endcap of the controller will
not be deformed!
Now the OptoSense sensor can be inserted carefully into the hole in the table top
from the top of the table. Eventually the sensing element has to be rotated by a
maximum of 90° until it can be inserted with little force into the controller. Once
the edge of the transparent cover of the sensor reaches the table top the force
must be increased up to about 200N to insert the cover into the hole. The cover
must be pressed in until the rim of the cover reaches the surface of the table top.
The retention force of the transparent cap is dependent on the material of the
table top. Should the force be too big (too much force needed to insert) or too
little (sensor comes out easily) the diameter of the hole in the table top must be
adjusted in 4/1000
th
” steps up or down until the cover can be inserted with
maximum 200N and the sensor does not come out easily.
Controller with GyroSense
The sensing element of the GyroSense for the collision detection is contained in
the controller itself. This is why the controller with the GyroSense option must be
mounted directly to the bottom of the table top as otherwise the movement of the
table top cannot be properly sensed.
The standard setting assumes that the controller will be mounted in parallel to the
cross bar which connects the two legs of the table. Should the controller be
mounted perpendicular to the cross bar, the configuration of the controller must
be adapted to that. Without that, a reliable collision detection will not be possible.
For the successful function of the GyroSense, it is very important that the table
stands with all four legs on the floor so that it cannot wobble. If the table can
wobble the GyroSense may react to the wobbling instead of a collision.
