DANGER!
Risk of injury from high pressure in the equipment/device.
▶Beforeworkingonequipmentordevice,switchothepressure
anddeaerate/drainlines.
Procedure:
→Connectthecontrolmediumtothepilotairport(1)
(3–7bar;instrumentair,freeofoil,wateranddust).
→Attachtheexhaustairlineorasilencertotheexhaustairport(3)
(see“Fig.12:Pneumaticconnection”).
Keeptheadjacentsupplypressurealways atleast
0.5–1barabovethepressurewhichisrequiredtomove
theactuatortoitsendposition.
Importantinformationfortheproblem-freefunctioningof
thedevice:
▶Theinstallationmustnotcausebackpressuretobuild
up.
▶Select a hose for the connection with an adequate
cross-section.
▶Theexhaustairlinemustbedesignedinsuchawaythat
nowaterorotherliquidcangetintothedevicethrough
theexhaustairport.
