0077 Safety Switch ‒ Control Cabinet

A control cabinet door is open far enough that the safety switch is not closed.

Close all control cabinet doors and make sure that the safety switches latch. Then activate the "Standby" button and restart the machine. It is possible that a reference run is started. During this time, the display "Operating system is working - please wait" appears. When the reference run is finished, start the machine again with the "Machine ON" button.

If this error message appears again despite the control cabinet door being closed, check the safety switch and the cabling.

A defective safety switch must be replaced immediately!
