Electrical engineering design for Eastern Westphalia, the Münsterland and the Osnabrück area

The work in detail

What electrical design here actually deals with

New plants on a blank sheet are the exception. The normal case is a plant that has run for twenty years, been extended three times, and whose documents no longer know about the last rebuild. These are the five situations we meet most often here.

1. 01

   Documents that no longer match the plant

   The 1998 diagram follows DIN 40719, the 2015 extension EN 81346, and last summer’s change is a pencil note in the folder. Before anything is designed, the actual state has to be recorded: opening terminal boxes, reading rating plates, tracing cores. A list of the differences between drawing and reality falls out of that work — and for maintenance it is often worth more than the new drawing itself.

2. 02

   Rebuilding while the plant runs

   In food and beverage production the shutdown windows are short and fall at night or at weekends. That changes the design, not just the schedule: each step has to be self-contained so the plant starts up again afterwards. Terminal diagrams that do not reflect this cost the electrician at three in the morning exactly the time nobody has.

3. 03

   The customer’s CAE system, not ours

   Companies here work in EPLAN Electric P8, others in WSCAD, older holdings sit in ELCAD. An external designer who masters only one system either forces a migration or delivers a foreign body into the existing set. We design in the system the plant is documented in — with its part master, its macros and the designation system already in use there.

4. 04

   Retrofitting discontinued controllers

   Simatic S5 with ET200 peripherals still runs in more plants in this region than one would assume — spare parts come from the second-hand market. In a changeover the controller is the easy part. The work lies in the interfaces to the existing peripherals, in whether the enclosure capacity is sufficient at all, and in twenty years of changes that never flowed back into the documents.

5. 05

   Manufacturing data for the panel builder

   Many panel builders in the region manufacture from drilling patterns, terminal and cable lists taken straight from the design. If the layout planning is only a drawing and not a data set, measuring and reworking happen in the workshop. That is exactly the point at which 3D layout planning pays for itself — or does not.

What we take on

The work companies here bring us

It usually starts with a plant that already exists and documents that no longer match it. Rarely with a blank sheet.

• 01Electrical designCircuit, terminal and layout diagrams for new and modified plants — in EPLAN, WSCAD or ELCAD, whichever your house works with.
• 02Technical documentation & revisionsBringing existing documents to a state you can rely on. It almost always begins with a survey on site.
• 04Digitising legacy drawingsConverting paper and PDF holdings into EPLAN, along with the list of what differs between plant and drawing.
• 073D control cabinet designLayout planning in space rather than on a plane, with manufacturing data for the panel builder.
• 08Project support & system solutionsSupport over the project lifetime — from planning to commissioning, with one contact rather than a distribution list.
