    we have Alco smart AZR can II. it have been tripped an alarm 03 and 04 IPA redundancy. i have checked all parameters and also clean all pipes, filters, etc but no improvement. sometime it is running 2 to 3 hrs normally but stop on these alarms any time. I observed it is not sucked alcohol from container but its solenoid valve operated well. please any one help me about these faults and how to eliminate them.

    Hi sir:

    1) safety device has tripped due to an excessive alcohol concentration level.

    2) Float in float housing dirty.: Clean very well

    3) Float housing leaky.: Repair or sealed

    4)Outlet blocked.: Clean

    5) Dampening solution supply too low: Increase

    6) Dampening solution supply interrupted: re- establish

    7)Dampening solution connector not properly connected: re- establish supply

    8)Supply pressure too low.: Increase dampening solution supply

    9) Level sensor dirty or defective: Clean or Replace

    Blessing

    dear sir chock
    already i have checked all these points but no improvement found. clean all sensors float and float housing. dampening pipe connector also remove and directed it. supply pressure found good about 2 bar plus. level sensor also working normally.
    one thing observed that its alcohol solenoid valve not sucked the alcohol properly. solenoid valve operated but its suction power not powerful.

    Replaces by long cycle of work :

    1) sensor( can be faulty) you did clean, but must be defective.

    2) solenoid( the shaft and winding can be defective)

    Hi sir:

    I believe that you do not have skill in Electronic/electrical background.

    1) you must test the sensors level+temperar: a) power supply to the sensor, since if you do not have 1) power s is problem 2) or the power supply is out of tolerance is problem , in Short test both and see, if there are o.k if the power supply is o.k , I strong recommend you to Replace , to due the Heavy duty cicle of work!!

    2) the same thing with the solenoid valve, you can NOT measure with ANY instrument the winding inside the must RE-heating, and by that reason is erratic function. I can strong recommend you to replace, to due the Heavy duty cicle of work!!

    3) otherwise, you are wasting: 1) time 2) money

    Good luck

    Blessing
