Special Machine Builder

Control Panel Design and Documentation Set

A complete EPLAN set for a new machine — schematics, panel layout, terminal and cable lists — drawn so the panel shop could build without asking questions.

Challenge

The customer was building a new special-purpose machine and had mechanical design covered, but no in-house electrical design capacity. Previous machines had been wired from sketches, which made every service visit an investigation.

Solution

A full EPLAN project: schematics with generated cross-references, panel layout with verified duct fill and calculated heat load, terminal and cable lists, and a parts list ready for procurement.

Result

The panel was built from the drawings with no queries back to engineering. The native EPLAN project was handed over, so the customer is not dependent on us for the next revision.

Two decisions did most of the work here. First, a numbering convention agreed at the start and applied without exception. Second, grouping terminals by cable route rather than by signal type, which is what makes both the wiring and the later fault-finding fast.

The I/O list was treated as the master document linking the drawings to the PLC program, and kept in step with both throughout.
