Connect a voltmeter to the + and – terminals for measuring the signal received on the
receiver unit, and look for the maximum deviation by optimising the direction of each cell.
The alignment controller SB51 can be used to optimise the positions of the transmitter
cells in the event of alignment problems.
When the beam cells
are correctly aligned, do not forget to set DIP switches 1 and 2
to OFF.

The values in the table above are given for voltages measured while the terminal is in
normal operating mode (DIP switches 1 and 2 are OFF on both the transmitter and the
receiver).
6. Using the alignment controller (SB51)
1. Using
The alignment controller SB51 is used to align the SB250, SB2100, SB450, SB4100 and
SB4200 detectors. It is equipped with powerful LEDs and a buzzer that indicate the signal
level received at the receiver module. It should be connected to the receiver module.
The frequency of the buzzer and the LEDs indicates the quality of the alignment. This
frequency increases as the signal received by the receiver beam cells improves and vice
versa.
