PROGRAMMABLE AGC(AUTO GAIN CONTROL) FUNCTION
When the beam power decreases in harsh environment by dense fog, heavy rain. This is a function to increase the receiving
sensitivity temporarily and to stabilize operation. The receiver adjusts this function to start or to stop automatically
depending on beam power from transmitter.
When the Programmable AGC works, the beam power level which already decreased recovers to certain power level and is
maintained.
When the Programmable AGC works, the environmental signal is issued, and it is continuing to monitoring the beam
power level while the environmental signal is issued.
When either upper beam or lower beam power decrease, the Programmable AGC works and the environmental signal is
issued.
When both upper beam and lower beam power recover to stable level, the Programmable AGC function and the
environmental output stop automatically.
In order to operate the Programmable AGC function correctly, it is necessary to set up
The margin of sensitivity is maintained even if there is a sudden worsening in weather conditions.

EXTERNAL ENVIRONMENT DIAGNOSTIC FUNCTION
This function outputs a notification before a warning is output as an environmental output when such impairments
as fog or heavy rain occur.
If such impairments continues for 20sec, an environmental output is issued.
<<Caution>>
Even if the beam power recover immediately, an environmental output is issued for at least 5sec.

LIGHT SENSITIVITY SIGNAL FUNCTION
This lights when there is an insufficient level of infrared light received by the
receiver, and it is judged that there is insufficient margin of sensitivity, and
inform you that adjustments are required.

ALIGNMENT WIRELESS CHECKER CONNECTION FUNCTION
By connecting an alignment
wireless checker (sold separately),
it is possible to transmit data
bidirectionally, check the monitor
output voltage of the receiver from
the transmitter, and simultaneously
switch the optical axis light
obstruction.
<<Caution>>
When using the wireless checker, please set
Auto Gain Lock switch "OFF" certainly.
