The analog and digital input and output signals are processed via analog and digital input and output channels. The signals and their physical values are linked internally with the functions of the HMI.

Analog input signals are used e.g. by controllers or the process display.

Digital input signals are used, e.g., for the following functions:

• Releasing controllers

• External unlocking inputs

• Burner START/STOP

• Switching on combustion air fans

• Switching on rotary cup atomizers

• Fault outputs
