thermalloadswhichexceedthelimitsspeciedintheoperat-
inginstructions.
General hazardous situations.
Topreventinjury,ensure:
▶Securesystem/equipmentagainstunintentionalactivation.
▶Observethedirectionofowduringinstallation.
▶Afteraninterruptioninthepowersupplyorpneumaticsupply,
ensurethattheprocessisrestartedinadenedorcontrolled
manner.
▶Don’tusethedeviceasaleverwhenscrewingthevalveinto
theline.
Failuretoobservethisoperatingmanualanditsoperating
instructions as well as unauthorized tampering with the
