HMI Repair

These days, it is hard to find modern day production machinery without hmis (human machine interfaces).

They certainly simplify the control and operation of machinery instead of having mechanical push buttons and illuminated switches; machine control is contained in one unit. They do suffer wear though; the good news is that most HMIs will let you know when they need a service. There are subtle things to look out for and if caught in time can save you an unexpected failure.

Quite often when the internal power supply is failing the HMI might take a few attempts to power up. When the backlights (the small fluorescent lights that are responsible for the brightness of the screen) start to fail, the screen becomes more dull than usual. The LCD screen may have lines running down it, this is the screen failing. Lastly, some of the push buttons may take a few more presses than usual or there maybe parts of the touchscreen that don’t respond as well as it once did. All these signs should be taken as the HMI is stating to fail.

The good news is that all these things can be fixed, whether you catch it early or when you do have a failure. HMIs are often highcost items and repairing them is cost effective. Any servicing we carry out is a full refurbishment of the HMI. What’s more, we will upgrade the backlights to LED types where possible as this improves the reliability of the unit when it’s returned back to you.
