How to input password

Recommended Posts

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.

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.

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.

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.

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.

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?
