Technical Remarks
■	The pressure dew point must be at least 15 °C under ambient and medium temperature and may not exceed 3 °C.
■	Builds up pressure slowly in the pneumatic systems, i.e. prevents a sudden pressure build-up during a restart after a mains pressure failure or avoids emergency OFF switching. This also avoids dangerous, jerky cylinder movements.
