Important notes for the enabling mechanism

In a numerically controlled plant, "setup mode" requires an enabling mechanism. The
enabling mechanism consists of the enabling button installed on the HMI device and the
corresponding logic in the HMI device.
The operating modes relevant for the enabling mechanism are:
● Setup mode
In setup mode, safety has to be ensured in a different way than in automatic mode.
During setup mode, personnel enter danger zones of the plant in which controlled
movements must be possible.
Movements must be executed with reduced speed in setup mode in line with the risk
assessment of the plant. Movement of plant parts should only be possible when the
enabling mechanism is activated. Operators must have been trained accordingly and
have detailed knowledge of the intended use.
● Process monitoring in manufacturing
This operation mode is used for processing complex workpieces, for example, or in cases
when parts of the workpiece cannot be inspected. This operating mode allows additional
manual intervention in line with DIN EN 13128 "Safety of machine tools - Milling and
boring machines". Unlike in automatic mode, the user is able to monitor and control the
processing process with open separating protective devices.
Safety instructions
Injury or material damage
Enabling buttons should only be used when the following applies for the person activating
the enabling button:
• The person can see the danger zone.
• The person is capable of recognizing personal injury hazards in good time.
• The person is capable of taking immediate measures to avoid danger.
The only person allowed to remain in the danger zone is the person who is activating the
enabling button.
Injury or material damage
If you trigger a command for a hazardous operating state with the enabling button only,
there is a risk of injury or material damage.
A hazardous operating state requires a second, specific operation with another key on the
HMI device. Consider this during configuration.
