Be cautious to properly align the pedestal in order to center the photoelectric beam sensor on
the reflector of the next pedestal.
In case several Pedestal rows (group of Pedestals) to be installed it
is mandatory every LSP3A being positioned in the same direction (all people
counter of each looking toward the same direction). This would prepare the
installation for future implementation of direction sensing.

4.3.3 Installing the Pedestal
Once the LSP3A will be powered, the photoelectric sensors will emit a red light beam. To
precisely align the sensors and the reflector, an orange LED is present on the back of the
photoelectric sensor. When the orange LED is continuously on, the sensor and the reflector are
perfectly aligned.
To see these LED, one must first unscrew the Plastic Bottom Cover covering the dual cells
(see picture of 5.6.1 Resetting the Counter Display).
On the contrary when the orange LED is blinking or off, then you have to adjust the
photoelectric sensor, so that the red light beam is centered with the opposite reflector. This
operation is achieved using a white paper to Clearly see where the red light beam is pointed at.
When perfectly centered, the orange LED will continuously be ON.
On Figure 4.6 below, the two Beam Crossing Cells support is shown. To do a fine adjustment of 2
beams, use a hexagonal key to screw or unscrew the top left screw (to adjust height of beams)
