While an HMI (Touchscreens) and a PLC are vital for machines and devices to work efficiently with human users, they don’t come without fault. You can’t afford to have long periods of downtime just because a part fails somewhere in your system. Getting your part repaired quickly and within budget is crucial, and this is something that sets Qualitrol apart from our competitors.

How do PLC repairs separate Qualitrol from the competition?

Qualitrol remanufactures PLC parts to provide affordable, trustworthy quality so your parts will work the first time and every time after that. With our certified technicians, rigorous testing, and perfect packaging, you can trust Qualitrol and our years of experience to deliver great repairs on your PLC parts.

Trust our technicians to get the job done right—all our repair and remanufacturing technicians are IPC 7711/7721 certified. This certification ensures that they’re the best people to do the job for the repair and remanufacturing of electronic assemblies. We use either exact replacements or the same components as the OEM to make sure your product runs properly. Anything that we replace, or repair will be indistinguishable from the original part or component. Any damaged connections, traces, or pads will be repaired. We maintain lead-free integrity with every component, and each board is repaired to meet or exceed OEM standards.

HMI repairs done right

Broken HMIs are a common problem and trying to fix them could be easy or complex depending on the problem. With so much usage, it’s important to know what the problems are with HMIs and how you can prevent them.

No one understands better than Qualitrol how important your machines are. Therefore we provide tech support for you regardless of your situation and for all models of the popular Siemens Simatic family of Human Machine Interfaces (HMI). The Siemens Simatic HMI family has had a long history of providing quality interfaces to machine operations – and Qualitrol can repair them all and backed by our one-year warranty.

Each Siemens Simatic HMI unit is hooked to the appropriate Siemens PLC system to confirm that it talks properly to the PLC. Once the Siemens HMI repair is complete, the Simatic HMI unit is fully tested again to confirm all functionality and connectivity to the PLC.

Qualitrol provides complete testing and evaluation of each unit before the repair starts for:

  • Screen brightness and clarity
  • Touchscreen alignment and ‘ghost’ touches
  • Cracked screens, torn touchscreens, or other damage to the front of the Simatic unit
  • Good contact of all keypads
  • Tightness of bezel, seals, and overlays to prevent penetration of moisture or dirt
  • Full function of all serial and ethernet ports
  • Ability to execute all functions appropriate to the specific model of Siemens Simatic HMI

Our goal is to get your Siemens Simatic HMI unit back up and running as quickly as possible so you can get your line running again. You can count on us to get it done right.
