All modern industrial machinery has safety features that often include shutting down the machine. Most machine owners are allowed to send mainteance in to evaluate the reason of the shutdown, resolve the issue and restart the machine, without calling the OEM.
Imagine if a walk-in cooler had a high-temp alarm, and the machine shut itself down, and locked the cooler as a result, then told the owner to call the cooler OEM. Thankfully it doesn't work that way, it might alarm then you diagnose (radiator fan not running, fan coils covered in leaves, whatever) resolve and restart.
