Qualitrol International is a repair center for all models of the Yokogawa HMI family of human-machine interfaces (HMIs). Yokogawa HMI repair work is critical if your HMI unit begins to fail. Getting repair work done provides a cost-effective alternative to expensive unit replacement.

The Yokogawa Repair Process

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

  • Screen brightness and clarity
  • Touchscreen alignment and ‘ghost’ touches
  • Cracked screens, torn touchscreens, or other damage to the front of the Yokogawa 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 Yokogawa HMI

The Yokogawa Repair Service

Each Yokogawa HMI unit is hooked to the appropriate PLC system to confirm that it talks properly to the PLC. Once the Yokogawa HMI repair is complete, the Yokogawa HMI unit is fully tested again to confirm all functionality and connectivity to the PLC. In addition to our HMI repair services, we also offer PLC repair, with the expertise to diagnose whether issues are HMI or PLC-based, and to respond accordingly.

Each of our Yokogawa HMI repairs is backed by our one-year warranty that covers the entire Yokogawa HMI unit. Our goal is to get your 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.
