With DIP 7 in ON (as default) and when the power supply LED lights up, the functioning of the RX optic
is verified.
The power supply of the heaters is set by default to 24V; 12V can be used by changing the jumper
configuration (SW4) on all optics and on the MES 9 C board.
The voltage can be both AC and DC.
Jumper J4 reads the value of the alignment signal, expressed in volts.
N.B.:The settings relating to the addressing of the optics are already set by default.
N.B.:The barrier can result in an alarm even if the WEAK SIGNAL LED is off.The cause may be the lack
of synchronism or a misaligned transmitter.
