Make Way for A Reliable Points Controller – International Application by PILZ

Modernization sets the pace

The main requirement when retrofitting the points controllers for the urban railway and trams in several of Poland’s major cities was safety and reliability. That’s because the control systems in use were obsolete and sensitive to temperature variations. In many places, points could only be passed at 10 km/h, which prevented attractive, clock-face scheduling. The Polish company ZUE S.A. is an expert in the field of modernizing rail infrastructure and took charge of modernization. This included: The railway-proven automation system PSS 4000. As the heart of the solution, it ensures safe and reliable points control – and, thanks to its modular structure and simple commissioning, it enabled the retrofit to be carried out while rail operations continued.

Robust and reliable solution for railway infrastructure

ZUE has been using the automation system PSS 4000 to retrofit points controllers since 2017: The points on the urban railway and trams can now be controlled safely in all weathers because, with its temperature-resistant modules and electromagnetic compatibility (EMC), PSS 4000 can withstand mechanical stresses such as condensation and increased vibration, even in unheated control cabinets. However, should an error or fault arise, this can easily be identified and located by the dispatchers thanks to the web-based visualization software PASvisu. With PASvisu, they constantly have an overview of all system components as well as extensive remote maintenance options. After the retrofit, the points in the Polish rail operator’s network comply with safety integrity level SIL 3. Passengers benefit because travel times have been reduced by 50 per cent on the modernized lines.

Conserving Power and CO2 Emissions with Premium Efficiency Motors

The process of converting electrical energy to mechanical energy is never perfect. As much as we would like to have a 100% efficient motor, it is impossible to build a machine that will take 746 watts of electricity (the equivalent of 1 Hp) and convert it to 1 Hp of mechanical output. It always takes somewhat more than 746 watts to yield 1 Hp’s worth of output.

Motors are continuously being pushed to be more efficient and reduce these losses. Over the years the guiding regulations of motor manufacturing have pushed us to improve efficiencies to new levels to reduce the considerable global power consumption of motors, as they are everywhere. From our factories, utilities and homes and most anywhere you can think of.

How much power consumption aka money are you spending that you do not have to? Take a minute while having your coffee to see if you can save money.
