B-COMMAND – Quality and Reliability Why 3-position enabling switches are so important If personal protection in the area of human-machine interaction is necessary, there is a distinction between normal and specific operations. Normal operation for robots, stands for automatic functions in which the operational protection mechanisms are active. The specific operation covers the installation, programming, troubleshooting and maintenance. During this work, the effect of the normal protection scheme must be repealed. To ensure personal security in this mode, additional measures must be taken....

By using an enabling switch the operator is able to prevent damage to people and equipment, in the case of an unpredictable behaving machine. Panicking people normally respond either by pressing firmly or by releasing the button: Both ways shutdown the machine reliably. PRODUCTS Highest Production Excellence and Reliability The enabling switches have redundant switching contacts and redundant actuators. With a suitable circuit the deviation of the switching states of both contacts can be detected as an error and the machine can be decommissioned, in spite of possibly damaged contacts. For...
