    Hi Guys,
    We have Polar 92 ED with not working photocells.
    We try to set up position of every photocell because we were thinking that they are not seeing each other.
    Without result.
    We have also Polar 66 so we instal on this guillotine at first right photocell from Polar 92, also only left photocell from Polar 92 and finally both photocells.
    Without result.
    All the time photocells from Polar 92 are only display two red led lights.
    Anybody have similar problem?

    Hi sir:

    Please see if Both LED's are OFF? if they are off, is indicative lack of power supply from +24Vdc.

    Look 1) C. Breaker F7+Fuse f11 , and of course connector x 415: pins 1+3 use the schematic diagrams for to located the connector

    2) Check interruption connections with the Emitter, measure the LED's if have 3Vdc excedding is interrupted, need to replace or repair.

    tips: a) use the schematic diagrams b) common sense( the most invaluable tools)!!!

    Let me know, sincerely

    Blessing

    Hi,
    Thank you for prompt replay, I am visiting quite often forum and I noticed that you are the most active member :)
    See the pictures which I made.
    Only this two LED lights are on. Now photocells are installed on Polar 92, the same situation was when I installed them on Polar 66. IMG_5991.JPG IMG_5992.JPG

    Hi sir:

    Thank you by his word .

    the Red Led ON, is indicative or lack of voltage as previously indicate you , use the schematic d b) tight and clean very well the connector, c) align emitter vs transmitter. Read very well my statements

    2) otherwise replace the Board light barrier.

    Blessing
