Safe automation

The safety aspect while designing machinery and equipment is crucial. We work together with machine designers and technologists. We continuously have in mind the risk scheme according to the standard ČSN EN ISO 13849-1, which works with the following input parameters:

– severity of possible injury – S
– frequency and/or duration of exposure – F
– probability of avoiding or limiting harm – P

Sample Case Studies

Stock holding and Cutting Al Semi-Finished Products for a Customer in Norway

Before the current production process, equipment for handling, storing and cutting yet-non-sorted semi-finished products using the technology Allen Bradley has newly been installed. The equipment is designed in the safety category SIL3. GuardLogix will replace the current ControlLogix, two Ethernet Point I/O modules, operator interfaces PanelView Plus 700, series-70 frequency convertors and new series-755 frequency convertors with the extension Torque Off are designed.

The Redevelopment of the Furnace of the Flotation Concentrate and Coal Slurry with a Power of 24 MW

The current redundant safety control system Siemens Simatic S5-135F is undergoing modernization these days. The newly designed control system Simatic S7-317F uses the security digital modules SM326. To control the pilot burner as well as the main burner, program safety function blocks intended for gas and oil burners are used.
