8.22.2. ADJUSTING THE PHOTOCELLS

The red light (8) is on when the Transmitter cell is fed and in proper working order.
The green stability light (10) is on when the Receiver cell is fed and in proper working order.
The orange operating light (9) is on when the Receiver photocell detects the beam. It therefore switches off when the cells are
not correctly aligned or when a gate user cuts the beam.
The sensitivity selector (11) is used to adjust the beam intensity.
The operating mode selector switch (12) must always be set to L (Light on) (= fully anticlockwise).
The photocells are adjusted in the three steps described below.
In all cases:
• Use an opaque, non-reflective material (e.g. cardboard or paper) to interrupt the beam from the cell being adjusted.
Step 1: Alignment
• Set the sensitivity selector (11) to the centre of the range (between min. and max.).
• If necessary, align the cell with the transmitter by acting directly on the photocell support until the orange operating
indicator (9) lights up.
Step 2: Adjusting the beam intensity
The purpose of this setting is to limit the strength of the transmitted signal, which could otherwise cause the detection to
malfunction.
• Set the sensitivity selector (11) to min. (fully counter-clockwise).
• Then turn the selector slowly clockwise to gradually increase the signal output until the orange operating indicator (9)
lights up continuously.
• Turn the selector switch by another 30°.
Too strong a signal will interfere with the passage detection!
Step 3: Final test
• Interrupt the beam on the transmitter photocell side and ensure that the orange light (9) goes out.
• Interrupt the beam on the receiver photocell side and ensure that the orange light (9) goes out.
• Pass normally through the lane and ensure that the orange light (9) goes out.
• For each of the three tests described above, make sure that the corresponding input on the AS1603 board, for the
transmitter photocell, and AS1605, for the receiver photocell, also goes out. If this is not the case, check the wiring and
connections of the cells.
