Hello every body

I am new in S5 please my CPU goes to the stop mode every time I switch on the machine.

Please see the attached files

Dear,
Here my best guess.

The "cause of interruption" shows the Flag NAU which stands for power failure (Netz AUsfall in german).

NEUZU means "COLD RESTART permitted as next start-up type."

SYSFEHL
STOP mode caused by system error (may be caused by user error,
e.g. overwriting system RAM with a block transfer or similar).
When a system error is marked,  a four-digit hexadecimal number/error code appears at the bottom edge of the screen.
In your case 40 10. 
Wher 40 is a system error
Where the manual of the CPU 948 tells
40 = System error
10 = "internal system error".

Is there still a program in the system?
