Product description
5.2 Solenoid with cable outlet
TheTypeAC19solenoidisanelectromagneticvalveactuatorfor
various Bürkert valves. As a so-called central screwed coil it is
100%separatefromthevalve.Thevalveitselfisaclosedsystem
evenwhenthecoilisremoved.
Thesolenoidconsistsof:
• coilwinding,
• coilhousing(madeofepoxide),
• electricalconnectioncable,
• controlelectronics.
Actuationispossiblewithalternatingordirectcurrentduetothe
integratedbridgerectier.Aversionwithelectronicpowerswitching
toreducethepowerconsumptionintheoperatingstateisoptionally
available.
Thecoilisplacedoverthecoreguidetubeofthevalveandfastened
withanut.Itispositivelysecuredagainstrotationtowardthevalve.
Theoutletoftheelectricalconnectionlineisperpendiculartothe
coilaxis.Thecableisrmlyintegratedintothecoil.Theunionnut
isnotintendedtoberemoved.
Themetal valve components arebroughtintoelectrical contact
withthecoilattheinterfacebetweenthecoilandthevalve.The
metalcomponentsmustbeearthedviatheprotectiveconductor
ontheconnectionline.
5.3 Solenoid with terminal box
The solenoid setup is identical to the description under “5.2”,
buthereaterminalboxisadditionallybuiltin(see“Fig.2”).The
terminal box is certified by EU type approval test certificate
PTB15ATEX1011UorIECExPTB15.0037U.
Thecableoutletdirectioncanbeselectedbasedontheordering
information.Thecableoutletdirectioncanbealteredlater,buta
specialtoolis needed for that1). Aconnection set for additional
potentialequalisation is optionally included,seetheinformation

DANGER!
Risk of injury due to electric shock.
▶Beforereachingintothesystem,switchothepowersupply
andsecureagainstreactivation.
▶Observetheapplicableaccidentpreventionandsafetyregu-
lationsforelectricaldevices.
Ifthereisnoelectricalcontactbetweenthemetalvalvecom-
ponentsandtheprotectiveconductorofthecoil,thereisarisk
ofelectricshock.
▶Alwaysconnectprotectiveconductor.
▶Checkelectricalcontinuitybetweentheprotectiveconductor
ofthecoilandthecoreguidetubeofthevalve.
With solenoids with terminal boxes, you must also ensure
that you:
▶Onlyinsertpermanentcablesandlines.
▶Usesuitablecableandwiringguides(seechapter“8”).Pay
attentiontotheprovisionsintheoperatinginstructionsincluded.
▶Intheterminalboxes,onlyconnectwireswithterminalconnec-
tionsmeasuringbetween0.5mm2and2.5mm2.
▶Tightentheterminalscrewswith0.25Nm.
▶Lockhousinglidproperly.Tightenlockingscrewwith2Nm.
▶Checktheconsistencyoftheprotectiveearthconnection.
▶Onlyopenthehousinglidwhenthepoweriso.
▶Thetemperatureresistanceofthecablemustbemin.15K
abovethemax.ambienttemperature.
▶Usecableendsleevesonexiblelines.
▶Theexternalearthconnectionterminals,suppliedinabag
andgluedintothehousinglid,mustberemovedwhen
installingthedevice.
