Bogdan Posted July 17, 2018 Report Share Posted July 17, 2018 Dear Gentleman, We have an compressor with unitronics controller and I am unable to input the password. Basically I do not know the keyboard combinations in order to input 0100 pasword (I think). The company who sold the compressor has bankrupt and there is no support at all.

Ofir Posted July 17, 2018 Report Share Posted July 17, 2018 Hello, First please note that Unitronics company is the PLC manufacture and as I understand KOMSAN is the company that made the machine using our PLC. In general to enter a value via the keypad is done by pressing on the key numbers. If you dont know the password then you will have to find a contact person from the company that made this machine.

Bogdan Posted July 17, 2018 Author Report Share Posted July 17, 2018 Greetings, Thank you for your fast response. Unfortunately I cannot do that. Basically all the characters from the display blinking randomly. Quote Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted July 17, 2018 MVP 2023 Report Share Posted July 17, 2018 It's been awhile since I worked with Jazz, but I think you can upload the PLC program from the PLC to U90 ladder. From there you can inspect the program to see what the password is. Quote Link to comment Share on other sites More sharing options...
Ofir Posted July 17, 2018 Report Share Posted July 17, 2018 If the screen is blinking usually it means that the screen is reloading but since I'm not familiar with the application I cannot tell. Maybe try to use the arrows to move between displays. Anyway as mentioned try to find a contact person from the company that made this machine.

Bogdan Posted July 17, 2018 Author Report Share Posted July 17, 2018 I have try everything. The only thing that it works is if we long press "i" we will access the menu. I can navigate thru this menu till I get the point "RUN". If I hit "enter" the PLC go back to above menu which means in Turkish enter the password. The main problem is that I cannot enter any password or I do not know the keyboard combination in order to be able to enter the password.

Ofir Posted July 18, 2018 Report Share Posted July 18, 2018 In this case please try to find a contact in Komsan. Quote Link to comment Share on other sites More sharing options...

Bogdan Posted July 20, 2018 Author Report Share Posted July 20, 2018 No. I didn’t try this and I do not now how to do it. If you will be so kind and guide me I will appreciate. Thank you Quote Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted July 21, 2018 MVP 2023 Report Share Posted July 21, 2018 Rather than duplicate effort, I'll just point you to Joe's reply in another thread. @Joe Tauser, can you confirm the correct communication cable part number for the Jazz (maybe MJ20...?).

MVP 2023 Joe Tauser Posted July 21, 2018 MVP 2023 Report Share Posted July 21, 2018 The programming cable for a Jazz is a JZ-PRG. You'll still need the U90 software and probably the USB to serial converter. Unless it's a JZ20 series, which has USB already. What is the model number of the controller? Joe T.

mfbalmustafa Posted January 27, 2021 Report Share Posted January 27, 2021 Dear Bogdan, I was a Komsan worker. nıow I made my private business at Airkom Komrpesor and can solve your jazz problems. if the display blinking the paramters were gone. you need connection to the plc and enter the parameters. Mostl probably the battery should be changed. if you dont use it more than a few weeks battery life time can be finish. you can check my new jazz program for Komsan or standart compressor on yotube. mustafa bal mustafa@airkom.com.tr Quote Link to comment Share on other sites More sharing options...
