The meaning of the letters in the PID diagram

What does PB mean in the diagram? It would be great if you could explain the control principle as well. Thank you
Remote/Local--Stop button.
This design is not standard – one solenoid coil receives signals from two sources; how can it be controlled? Insert an operator or something first before giving it to the coil.
Regarding the local components and the pressure selection? I’m not quite sure; could you explain it in more detail?
Is it a push button, a reset button? Looking at the diagram, this control valve is equipped with an interlock solenoid valve; does this PB serve to manually reset the solenoid valve on this control valve after the interlock has been disabled?
