DIGITAL INDUSTRIAL CONTROLLER
english
The Digital Controller carries out a self-test each time it is switched on. The data
memory, the program memory and the non-volatile memory are checked during the
course of the self test.
Correct functioning of the inputs and outputs can also be tested during operation. If
an error occurs, it is displayed in the second line of the display. The error display
does not disappear until the error has been remedied.
The controller assumes the MANUAL mode whenever an error occurs.
Error mesages during the self test:
