For the
Laser guard model, the “Neutralization” or “Muting” function is also previded, that is the possibility of being able to suspend in temporary way
its own protecting function. That it means that when the two dedicated inputs are simultaneously activated (within a maximum time of 0,8 second) putting
separately in short-circuit the PINK and GRAY conductors to the “0V” of power supply (RED conductor and Shield), the Laser Guard surveillance action comes
temporarely neutralized, allowing that the Laser beam can be darkened without that the output signal switching devices (OSSDs) switch to the inactive OFF state. A
red color blinking signaler, situated on the top head of the “RX” section (Pag.8), shows the activation of the Muting function. In the event of the two dedicated muting
inputs are not simultaneously activated, or however with a time delay more than 0,8 second, the RED4-RL switches into the block state opening the output signal
switching devices (OSSDs) and signaling it as the “D” case of the diagnostic table of Pag 8. Make attention using this function as it could generate potentially
dangerous situations. Adopt a visual and/or acoustic additional external signaler to indicate in unequivocal way the inactivity state of the Barrier to activated Muting.
