Working Principle
The operator selects a loop or uses dedicated keys to adjust setpoints and control modes. Key commands are transmitted over USB to the HIS, which updates the process display and sends the corresponding commands through the control system. Audio signals are transmitted over the separate USB audio channel to the integrated speaker.
Installation Requirements
- Connect both USB connectors directly to the supported HIS personal computer.
- Install the keyboard on a stable desktop or approved mounting surface.
- Maintain the specified operating temperature and humidity.
- Verify the suffix configuration and compatibility with the HIS software.
- Use the correct documentation and licensing or option configuration for the system.
Usage Precautions
- The AIP831 hardware specification and supplier descriptions of an eight-loop keyboard share the same model, so the suffix and HIS configuration must be confirmed.
- Do not force USB connectors into incompatible ports.
- Keep liquids away from the keyboard.
- Verify software and hardware compatibility before commissioning.
- Replace the unit only with the same order code and compatible revision where required.
