In order to ensure that the CE certification of the machine is retained while retrofitting of a ToolScope into an existing machine tool, the retrofitting must not result in any additional risk from the machine.
The following rules must 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 release in accordance with its security concept, these (blocking) flags / wires are added by means of a logical OR link.
