WARNING
Risk of injury due to improper maintenance.
▶Onlytrainedtechniciansmayperformmaintenancework.
▶Performmaintenanceworkusingsuitabletoolsonly.
Risk of injury due to unintentional activation of the system
and uncontrolled restart.
▶Securethesystemagainstunintentionalactivation.
▶Ensureacontrolledrestartaftermaintenance.
8.1 Maintenance work
Iftheinformationintheseoperatinginstructionsforusingthevalve
isfollowed,thevalvewillworkwithoutrequiringmaintenance.
8.2 Faults
Iffaultsoccur,checkwhether:
• thedevicehasbeeninstalledaccordingtoregulations
• theelectricalandpneumaticconnectionshavebeenproperly
set up
• thedeviceisnotdamaged
• allscrewshavebeentightened
• voltageandpressurehavebeenapplied
• thepipelinesareclean
8.2.1 Valve does not actuate
Possiblecause:
• Shortcircuitorcoilinterrupted
• Core or core area contaminated
• Operatingpressureoutsidethepermittedpressurerange
8.2.2 Valve does not close
Possiblecause:
• Interiorofthevalvecontaminated
8.3 Install pilot control
WARNING
Risk of injury from looseness of valve.
▶MakesurethattheO-rings/sealstthevalveproperly.
Overheating, risk of re.
Connectingthesolenoidwithoutrstinstallingthepilotcontrol
willleadtooverheatingandwilldestroythesolenoid.
▶Onlyconnectthesolenoidafterinstallingthepilotcontrol.
NOTE
