    Hello All,

    We have a problem with an IR Dryer not switching on properly. On power up, the front panel ComCon110 unit boots up normally, cooling blowers will come on but an error is displayed accompanied with a red blinking LED. The error is:

    A30: Current line unknown.

    The unit does not allow you to continue operate as the error apparently has to be cleared first which we can’t find how.
    Checked on its user manual and A30 is apparently related to the lamps but does not mention the error we are getting. Checked the lamps, the power supply and contactors but all seem OK. Machine still down.
    In view of the above has anyone encountered such an error please and how to rectify it? - Or may be someone can send me the schematics of this unit?

    Dryer type: Piller IR-Trockner SM74

    Thanks in advance for your help.

    Hi, sir
    Good morning
    I see that you have Piller IR Dryer.
    Not mention if your Dryer is Normal or Extended Delivery and Frecuency 50-60HZS or for Ink or Coating dRYER Model
    Your problem mentioned is ErrorA30 : that means: 1) The electronic pulse for AEG Thyristor regulator is NOT issued: Test the Thyristor with a Good
    DMM or Devices for Electronic Components, for a competent Electronic Tech or Eng, for Test. see your Schematic Diagrams
    2) Test However the +24Vdc in your power supply the Tolerance is very Close like: +-2% WITH a Good DMM like FLUKE or Similar
    3) Please Re-test your Cooling system Device(Hoses, Pump, or Compresor, clamps any device relationed with the system.
    4) Fans in Ceiling too, RETEST it. with a Good DMM.
    Of course can be another Reason, but please test this FIRST.

    Hello Chock,
    Good morning.
    First of all thanks for your reply.
    The dryer is a normal one for Ink with a high pile delivery. The frequency is 50Hz. The error appears immediately as soon as it boots up as apparently performs some sort of self check before it lets the user to operate. So I think the thyristor would not become activated yet. The 24Vdc supply is correct. Compressors and cooling fans were individually tested and works fine.
    We would appreciate if we can have the electrical diagram/layout of this unit, because its not incorporated with that of the machine.
    Thanks for your support.

    Hi Davianafg,
    If you are still having this error A30, to solve the problem, you have to change the lithium battery in the PLC(ComCom) to type CR2450 by either Eveready, Toshiba, etc. The lifespan of these batteries is about a year, so on installation it would be recommended to instal a new battery.
    Pls do this and let's know the result. Good luck.

    Hello Wunmi-50,
    Last time I checked the battery, it had correct voltage.
    Unfortunately this week I'll be away from this machine and won't be able to continue checking it for the moment. I will continue and post again next week.
    Thanks for your help.

    Hello All,

    Following all checks I decided to reteach the characteristic - although the error is not mentioned in the service manual! Then the lamps came on and the error cleared. IR unit worked OK then.
    Thank you all again guys for your help.

    Dear Sir:
    Hi hope you are well in union with his family.
    The problem that you have is with the Thyristor regulator AEG, No pulse arriving for excite the Gate of
    the same electronic Device.Can be there excessive plate Temperature.
    You must install some additional Fan, for to help reduce the temperature.

    We have an A30 code and have tried the items suggested,but no luck. I have an electrician that says he would need a diagram to fix it, it's a Piller 1998 serial # 86736 400v/3. Any info would be appreciated!

    You need, electronic Tech or Engineer, they have more skill and knowledge for this kind of equipments.
    They can use the Oscilloscope, in order to test the pulse for Thyristor.
    Electrical is Not dominion for this kind of tech electronics Devices.
    Let me know please
    Blessing

    Was the dryer in production? Did you have power cut off or failure recently? i don't have the manual in PDF but if you have Dryer instruction manual, you have to find the procedure for Power Line Synchronization. You need to log with password into service on ComCon and then follow the instructions. It takes few minutes and you can see lamps turn ON, OFF and dimming and OFF again. Then the unit is ready to run.
