Maintenance and test
The emergency stop function must be activated and tested before commissioning after each installation or
reinstallation of the machine.

Also see section 7 of this instruction manual.
The safety function complies with EN ISO 13849-1:2015.
The emergency stop function is constructed as a Category 3, PL d.
Speed monitoring of the movement of the X axis and the Print head (optional)
The speed monitoring of the movement of the X axis and the print head is a safety function, with the purpose of
preventing them going faster than 250 mm/sec. If the limit is exceeded, the machine is stopped.
The speed monitoring is optional and comes together with the perimeter guarding which also is optional.
If the application requires a speed higher than 250 mm/sec. for the X-axis and print head, the perimeter guarding
together with an interlocked door must be installed. When entering the guarded zone, opening the interlocked
door, the speed of the X-axis and the print head is automatically reduced to 250mm/sec and is then monitored by
the speed monitoring as long as the door to the guarded zone is open. As soon as the door is closed the speed is
automatically increased. See also Interlocked door.
