Siemens Central Ac Control Manual

[Kandy Swartzel]

SiemensMobility works with customers to improve the efficiency, reliability, safety and environmental standards of road and rail transport. It is part of Siemens AG (Berlin and Munich), a global technology provider, active in more than 200 countries and focusing on the areas of electrification, automation and digitalization.

The UK Government-sponsored Thameslink Programme is set to transform north-south travel through London, with 24 trains per peak hour through central London in December 2018, twice as many direct services between Brighton and London Bridge, longer carriages and more seats in morning peak time.

As part of the Thameslink Programme, new trains built by Siemens Mobility are due to begin operating in the spring of 2016. The fleet of 115 trains is comprised of 60 eight-car trains and 55 twelve-car trains totaling 1,140 vehicles. Looking after these over a period of 30 years is the responsibility of Siemens Mobility, which was awarded the contract to build the train and two new train depots; and undertake inspections every 20,000 miles, and significant overhauls after one million miles. Under the terms of a demanding performance regime, any issues with regard to the availability of trains will result in a direct penalty, so an effective maintenance regime is central to the success of the contract.

In line with the significance of the whole project, Siemens Mobility has adopted an innovative alternative, a first for the United Kingdom rail industry. It has chosen to extract the content for instruction manuals directly from core engineering data, so that maintenance teams are drawing on exactly the same information as the manufacturing department. The overall aim is to improve performance and increase knowledge and control by compiling manuals in-house. Teamcenter software, from product lifecycle management (PLM) specialist Siemens Digital Industries Software, is playing a key role in combination with Cortona3D RapidAuthor software solutions. Cortona3D is a Siemens Digital Industries Software technical partner.

Teamcenter is used to obtain computeraided design (CAD) models and bills-of-materials (BOM) data directly from the enterprise management system and create the manual structure. Cortona3D RapidAuthor, which is fully integrated with Teamcenter, is used by authors to transform the models into 3D animations. As the author produces the animation, RapidAuthor begins to produce the words for the steps required to explain the task. The author then uses an eXtensible Markup Language (XML) editor within RapidAuthor to add safety information, steps and graphics to the procedures. Teamcenter then structures graphics and text into numbered pages and publishes the final document.

Each manual is in three parts: the basic details of the task, the specific procedure and functional testing. This enables a mix-and-match approach for routines that have overlapping tasks. The first section is a short description that highlights safety precautions and any specific competencies, materials and special tools required. The second section includes a marker with a link to the 3D model. This shows moving parts and demonstrates exactly how to remove or replace a component, particularly within small spaces. The final section is a clear and concise checklist to confirm completion, testing and asset management.

Ben Wardle, production manager, is responsible for validating the 650 tasks presented in the manuals. He leads a team of technicians undertaking maintenance on trains that have come off the assembly line in Germany and confirming that instructions are both accurate and achievable.

Scheduled overhauls, preventive maintenance and specialist procedures such as ultrasonic axle testing on a fleet of 115 trains allow for only one train to be unexpectedly out of action at any time. Minimizing the time that a train spends in a depot is therefore crucial.

The second step is to provide clear and precise instructions. With the new solution and the work of the validation team, technicians have exactly the right information at the right time. As well as accessing 3D interactive data via a hand-held device, they can also print PDF documents easily. All instructions include the exact configurations for each serial-numbered vehicle, with any customized options and precise information about specific pieces of equipment.

One of the major benefits of the solution is the control and flexibility that it delivers. By building and retaining knowledge in-house, communication is better and expenditure is controlled. If there are any engineering changes, new information will automatically flow from Teamcenter into the documents, whereas previously all change control was done manually.

These multi-drive Control Units increase axis count and functionality. They have an Ethernet port, as well as more I/O and controller to controller communication. Each unit can manage up to 6 servo or vector axes in a high performance system. For standard systems, up to 12 V/Hz axes can be controlled from one CU320-2 unit. These Control Units significantly reduce system costs, as they increase functionality for positioning, safety integration, and drive control allowing all these functions to be controlled by one unit versus several.

The CU320-2 DP is a Sinamics Control Unit with a Profibus interface. It is a central Control Module in which the closed-loop and open-loop functions are implemented for one or more Line Modules and/or Motor Modules. It can be used with firmware version 4.3 or greater. It has 12 digital inputs, 8 digital inputs/outputs, 4 DRIVE-CLiQ interfaces, a Profibus and Ethernet interface, a serial interface (RS232), an option slot, and 3 measuring sockets.

The CU320-2 PN is a Sinamics S120 Control Unit without a Profibus interface. It has the same interfaces as described above, however without the Profibus port. It is also a central control unit with closed-loop and open-loop functions that can be implemented for one or more Line or Motor modules.
