Blocked on Emergency STOP .

[ciose]

Hi , i own a Modig MD 5000 [1985] CNC . Very old but i want to work with it . it works with HH Tnc 155P controller . I have a huge problem . When i start the machine , it says "Speicher test" then this appears : "Stromunterbrechung" . I don`t know German but Google told me that means "Current interruption" . When i press any key , it says "Not-Aus PC' which means "Emergency stop" . How do i solve this problem ? I can access the parameters , i already reset these . I entered in PLC editor or something with 951026 CODE . I didnt changed anything , i pressed END key . Since then i cant start the machine . Please help me
