Instruction Manual - Original Version
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.
Components included in the safety function
Interlock.
The Interlock is an electrical safety
device.
The safety device may be coded to
prevent bypassing.
The safety device is installed on the
doors to the guarded zone:
Safety controller.
Intelligent controller monitoring the
safety function.
The service life of the safety
controller is 20 years.
The safety function i.e. the machine
must not be used beyond 20 years.
The use beyond 20 years is
conditional to the fact that the
relevant components are replaced by
new components of identical or
improved properties than the
original ones.
The safety controllers are located in
the control cabinets.
Servo drives.
Reduces the speed on the following
moving parts.
- X-axis (For-, Backwards);
- Print head (Sidewards);
The service life of the servo drives is
20 years.
The servo drives are located in the
control cabinet.
When the door is open, the status will appear on the operator monitor:
”Door open, running with reduced speed”
The safety function operates unchanged in any operating conditions of the machine.
The safety function must be activated and tested before commissioning after each installation or reinstallation of
the machine.
Test by opening the door, speed must be reduced to 250 mm/sec. When door is closed, speed is increased again.
As a minimum, the safety function must be visually checked and activated at least once a day.
Also see section 7 of this instruction manual.
The safety function complies with EN ISO 13849-1:2015.
The speed monitoring function is constructed as a Category 3, PL d.
