Shutdown process

When the main switch is turned from 1 to 0, the machine is immediately switched off. Dangerous movements are immediately stopped. However, the machine data are not lost, as they are saved with a battery. This takes approx. 60 seconds. In the process, messages appear on the touch screen. Once the process is complete, the touch screen becomes dark.

Even with the main switch switched off, the mains supply up to the main switch still carries current with extremely high voltage. The mains supply must be disconnected and secured against being switched on again before working on the main switch unit.

Emergency-stop

The main switch is also the emergency-stop switch.

The main switch has to be locked during maintenance and service work. This prevents the main switch from being switched on accidentally.
