To assure that the CE certification of the machine is retained when a ToolScope is installed, the retrofitting must not result in any additional risk from the machine.
If a machine already has a CE mark and no additional risk is added, the CE mark is kept valid.
The following rules apply, in order to guarantee this:
- Alarm outputs are never wired directly to a signal with the effect of a movement release or with an unsecured effect on a movement release.
- Alarm outputs are instead connected to flags / wires. At a place where the machine manufacturer deletes the movement clearance in accordance with its security concept, these (blocking) flags / wires are added by means of a logical OR link.
