System down in powerless mode
The system goes down in powerless mode when:
•
Start key in position 0 and no activity signal has been sent.
•
Start key in position 0 and hold circuit's run time has expired and

been activated.
The following takes place when the system goes down in powerless
mode.
1.
Control unit cab (D790-1) cuts off manoeuvre switch volt-
age(15E).
