When your Siemens S7 PLC stops communicating or throws mysterious error codes, production stops. This guide walks through the systematic diagnostic process used by industrial repair specialists.

IGBT module failure is the most common catastrophic fault in frequency inverters. Learn what causes it, how to confirm it, and why professional repair is often faster and cheaper than buying new.

A dead HMI panel brings the entire operator interface to a standstill. This article covers the most common failures in industrial touchscreen panels and explains when repair beats replacement.

Fanuc controls power the majority of CNC machine tools worldwide. When they fail — especially with alarm codes 360, 431, or 5136 — the machine stops. This guide covers diagnosis and recovery options.

When a PLC controller dies and the production line stops, every hour costs thousands. We repair Siemens SIMATIC, Allen-Bradley ControlLogix, Mitsubishi MELSEC, Omron CJ/NX, and Schneider Modicon at board level — faster and cheaper than any OEM replacement.

A broken crane controller means the entire factory floor stops. We repair frequency inverter drives, brake control units, and PLC panels from Demag, Konecranes, Stahl CraneSystems, Terex, and Abus cranes — with emergency 24-hour turnaround available.

Modern offset and digital printing machines are packed with proprietary electronics: servo drives, ink management controllers, colour registration systems, and CIP4 interfaces. We repair them all — without waiting months for OEM spares.

Switching power supplies are the lifeblood of industrial control systems. When a SITOP, Phoenix Contact, or Puls power supply fails, it can take down an entire control cabinet. Here is how to diagnose and recover.

A broken elevator controller in a hospital, hotel, office tower, or logistics warehouse is not an inconvenience — it is a crisis. We repair Schindler MiCOM, Otis Gen2, KONE MonoSpace, ThyssenKrupp Evolution, and Mitsubishi Elenessa drive and controller boards at component level — restoring service in days, not months.

When a three-phase industrial UPS fails in bypass mode, every critical load it protects is exposed to raw mains — unregulated, unsynchronised, and vulnerable to the next power event. We repair three-phase UPS inverter boards, rectifier modules, and control electronics at component level. No load bank needed — we test on-site.

A failed VFD stops the motor. A stopped motor stops the process. Whether it is a pump, fan, compressor, conveyor, extruder, or centrifuge — if the inverter is dead, production is dead. We repair industrial variable frequency drives from 0.37 kW to 2.2 MW at board and component level, without OEM lead times.

Autoclave controllers fail with door lock errors, pressure sensor faults, and failed sterilization cycles. Board-level repair restoring IQ/OQ-validated operation without costly module swaps — 48h turnaround, 12-month warranty.

X-ray generator boards fail with IGBT inverter faults, kV/mA regulation loss, filament errors, and HV arcing. Component-level repair avoiding €8,000–40,000 OEM generator replacement — 48h assessment, 12-month warranty.

Surgical table controllers fail with hydraulic valve driver faults, axis position errors, battery backup failures, and remote handset issues. Component-level repair with no loss of table presets — 48h turnaround, 12-month warranty.
