1)	(after switching P to T)
2)	Attention! The applied pressure adds to the set pressure! The switching pressure differential remains unchanged within the setting range!
3)	The tank pressure must not exceed the pump pressure.
4)	For switching pressure differential adjustment, the following points must be observed:The top and bottom switching points must be within the setting range of the pressure rating (e.g. for a pressure rating of 100 bar: top switching point 100 bar, bottom switching point 50 bar ≙ 50 % switching pressure differential)– The minimum switching pressure differential mainly depends on the system (set pressure, pump and actuator flow, accumulator size and preload, line length and resistance, etc.) Here, the valve offers the possibility of optional adjustment of the switching pressure differential to the system. For these reasons, however, the minimum adjustable switching pressure differential of the valve cannot always be realized at the system. – Generally: Reduce the tubing between pressure cut-off valve and hydraulic accumulator to a minimum and ensure depressurized pilot oil (Y) discharge as possible. – For the switching pressure differential factory setting, refer to the respective information sheet.
5)	Type DA …FS... 150 to 315 bar
6)	The cleanliness classes specified for the components must be adhered to in hydraulic systems. Effective filtration prevents faults and simultaneously increases the life cycle of the components. For the selection of the filters, see www.boschrexroth.com/filter.
