What are HMI devices?
HMI, or human-machine interfaces, sometimes referred to as operator interface devices, are complex yet integral to industrial automation. They allow end-users to monitor the status of the industrial processes at play and also provide the ability to control them. ICR engineers have also developed testing equipment to complement the ICR technician’s broad technical knowledge base that’s required to repair HMIs.

How we repair HMI devices
ICR computer lab technicians possess the skills required to repair or refurbish industrial computers, monitors, and human-machine interfaces (HMIs). Many of the items we receive have already become obsolete, and support has lapsed from the original equipment manufacturer (OEM). Because of our broad knowledge base, ICR technicians can restore obsolete equipment back to original OEM settings and condition. Before repair, ICR technicians utilize dynamic testing to determine the condition of the devices. Then, after a thorough inspection, components are replaced based on the part under repair or refurbishment- services all included in our preventive maintenance program. During the final testing phase, equipment and parts are checked for functionality, including linearity and logic unit functionality.

Lower overall costs with LCD Conversion
ICR developed a process and procedure to replace CRT deflection assemblies with a modern LCD display. Analog deflection circuits and CRT components are first removed, and then re-engineered with new digital LCD technology with technicians being careful not to comprise the original functional specifications of the units. Additionally, features like remote control ability to adjust display specification can be applied to LCD technologies.
