    Our Polar 92EM works intermittently, maybe for one or two days at a time and then stops. When we go to make the first cut the blade stops before cutting and then we get error code 85.
    Any help with resolving this would be greatly appreciated.

    Hi sir
    You must test the following for his problem Error code 85
    1) ALL lights LEDs ON in cards HK and IAR

    2)Check adjustments of limit switch
    S22a and S22b at the gear box( see his schematic diagram)

    3)Check Adjustments the Light Barrier again(see his schematic diagrams)

    4) If after all mentioned steps are o.k, you must TEST AND exchange boards: HK +IAR+AR ++KK

    On cards HK and IAR; most lights on HK board, but not the set of red lights at the bottom. Lights appear to be ok on IAR board.

    Maybe are Faulty, proceed with my steps, and use the Schematic Otherwise
    you will lose the time, and money.
    Need test all the power supply for VDC.

    Hello,
    Can you help me. I have Polar emc 155
    For some time after cutting the sheets stuck and displayed error 85.
    After manually lifting it to the top point it starts cutting again.
    Once stuck as I move one of the two sensors s22a and s22b is fixed briefly.
    Several masters came and nobody could find the problem.
    How can I check if the problem is in the sensors or one of the boards.
    Thank you

    Hi Sir:

    Normally you must adjust the limit switches S22a+ S22b IN GEAR BOX.
    Adjust light barrier the emitter vs receiver.

    Otherwise you must replace or HK, OR IAR, o KK, OR AR

    Hi sir:

    Interruption within the respective emitter circuit link:
    Check connections according to wiring diagram

    Emitter LED’s:

    If the voltage on any emitter-Led is exceeding 3 V D.C., then the LED is interrupted Exchange card LS

    Short circuit of any emitter LED:
    If the voltage on any emitter LED is less than 0.5 V D.C. it is to assume that this LED has a short

    Exchange card LS.

    Check connection LS 600 - CU 4

    Hello Peter,
    It is a complex trouble because there are some cards involved in the handle of the upstroke movement of the knife.
    I would start by checking the microswitch associated to the cams and it adjustment. After this, the things go more complex because at least four cards are involved in the managment of the signals.
    Additionally, like Chocck has been explained, the most of the times the origen of a trouble like this may be electrical or electronic.
    You need qualified personal in this case.
    Best regards to you

    Hi sir I did indicate you.

    1) before adjust limit switch s22a+ 22b in the gear box, very well, clean limit switch or sensor if can be defective. Loose wires or dirty contacts or defectives, replaces it!!

    2) Safety Bolt, test + 42 VDC, loose wires , limit switch or sensors defective!, Or bolt solenoid Overheating!, Not Burn. Or lack of LUBE, do it with graphite erase pencil ( little secret).

    3 ) test Regulated Power Supply, very well in tolerance 0.7% up.or down, example if you are measure :+ 5Vdc, and you get 5:3Vdc, defective or ! Replace it or Repair ir. And similar for the rest of Voltage.

    4) Hydraulic system need Refill completely!!!, And then Bleeding very well all the system, see x the eye measure hydraulic bin front.
    By other side look x Leakages!!!!!.

    Let me know, sincerely.

    Blessings.

    Hello Sir,
    I started to follow your steps
    On the second step ( 2) Safety Bolt, test + 42 VDC, loose wires , limit switch or sensors defective!, Or bolt solenoid Overheating!, Not Burn. Or lack of LUBE, do it with graphite erase pencil ( little secret).)
    I measured the voltages of the safety bolt and it showed + 52,2 VDC
    Is this a problem or is it OK that it doesn't show + 42 VDC?

    Thank you

    Normally is to High, for 52,2 Vdc, you must adjust the transformer in Primary to lower the secondary, and that way lower the 52,2Vdc.

    However with the Voltage 52,2 Vdc, is there action of the safety bolt? , If NOT working is signal that solenoid is Overheating or defective, try to lube first, and if NOT work, repair or replace it. !!

    Let me know, sincerely

    I see that is working very well.

    The bolt , if you can do it for yourself, you can fix it using: "comon Sense ".

    Otherwise you must go to some shops mechanic, and get to tighten.

    Blessings

    Hello Sir,
    I replaced the limit switches with new ones,
    cleaned the safety bolt and now it works perfectly.
    Things have improved considerably. Before the cutter was sticking at 10 shears or less, now it is sticking at about 50 shears.
    You had written to me about a sinewave that can overheat, could you describe what it is and how to tell if it is overheating

    Thanks so much for your advice
