7.4 Manual actuation of the actuator via
pilot valve
Theactuatorcanbemovedwithoutapowersupplyfromtherest
positiontoitsendpositionandbackagain,when the control air is
connected.
Todothis,thepilotvalvemustbeactuatedwithascrewdriver.
NOTE!
The hand lever may be damaged if it is simultaneously
pressed and turned.

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.
WARNING!
Risk of injury from improper installation.
▶Installationmaybecarriedoutbyauthorizedtechnicians
onlyandwiththeappropriatetools.
Risk of injury from unintentional activation of the system and
an uncontrolled restart.
▶Securesystemfromunintentionalactivation.
▶Followinginstallation,ensureacontrolledrestart.
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.11: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.
