Hello!
I own a Gildemeister NEF CT 40 Lathe and i think i have some problems with the CNC board. When i turn on the machine, i get these messages:

DISPLAY AND GRAPHIC INTERFACE......0.064.110. 6-MAY-1987 INITIALIZED
OPERATING INTERFACE............???????????..??-???-???? ERROR
NC_PROGRAM MEMORY......................INITIALIZED
NC_PARAMETER MEMORY...................INITIALIZED
MACHINE ADAPTABILITY..............

5 SYSTEM ERROR

CURRENT SEQUENCE 157-30-0103/082
STROMLAUFPLAN

I bought the machine second hand and it came with these errors.
On the CNC board there are some green lights, one yellow light and one red light. The yellow light is for MR2 (whatever that means) and the red light is for RS (whatever that means)...
Some data i found written on the board: Operator Interface, SET-10 AES 0 ; IN 0.853.255 ; MEM ADR C000 ; SN4988111 .
I don't own any parts drawings or electrical parts drawings. Can anyone help me find the problem and fix it? Thank you a lot!
