    Hello .. I have error 125 (high pressure monitoring) in the technotrans. the problem is that the fault is not eliminated. I have tried with password 31 and 4321 but the failure continues. if anyone knows how to remove the fault please.

    Does the error go away and then come back? You need to have a refrigeration expert look at the problem, in case of a water cooled system there is no sufficient external cooling water flow or in case of air cooled system the condensor coil is not being cooled

    Send more details about the unit. A photo from plate would be helpful. If you have air cooled system, check the condenser if it is clean. You can clean it with blast air. If it is water cooled, then check coolant circulation. There are gauges inside the cabinet show coolant fluid pressure. You can also read inlet/outlet temperature.
    In order to acknowledge this error, you have to make a reset on high-pressure sensor. They defer from unit type and year of production. On old units, there are two silver boxes close to compressors with a black bottom for reset. On new versions, you have to find a small black box with a blue bottom connected to compressors. After that you can (acknowledge) eliminate the error by login to service 2 level.

    Let us know the result.

    Good luck.

    I took their advice into account and made a review.
    The system is cooled with water. I already checked all the temperatures and pressures and they look good. I did the following test: I changed the "bus com" module to another machine and the fault was passed to the other machine, which makes me understand that the fault is in the memory of the "com bus".

    check the external cooling water supply
    reset the error by pressing HP switch&in monitor by entering password...
    check the heat exchanger ---may be its block ...
    above every thing ok then check actual pressure values in the display in sensor menu...
    still problem means either HPswitch Or HP sensor failed ....

    goodluck

    thank you all, check all the parameters, sensor, pressure switch and everything is in order, but the failure continues. all that remains for me is to change the "multicom processor unit."

    Since the system is water cooler so there will be no fan on top side.
    You have check external water circulation and is working ok.
    For time being fix a pressure meter(gauge) on the compressor and check pressure
    For just checking by pass the pressure switch ( normally it is nc switch) .
    If by doing bypassing compreaor gets on then either Sqitch is faulty or gas pressure is high

    Reset the high pressure sensor and eliminate the error on the screen.
    Otherwise check the actual pressure in the circuit by calling a refrigeration expert; if everything is in order you can change the high pressure sensor; it may be defective

    Hi if resetting the high pressure sensor did not solve the problem you can delete all the error messages by entering the code 301;)
    You will not need to change the multicom processor

    Good luck

    Thank you very much Mr. Adil. Tomorrow when I am in the company I will put his advice into practice.

    I greet everyone. the solution to technotrans fault 125 was to change the multicom module of which I had already uploaded images. the waiting time was fueled because the module did not appear locally and it had to be requested outside the country. Thank you.
