1 DESCRIPTION 2 TEChNICAL DATA
Thedrivercontrolsonesolenoidofaproportionalvalve.
Hisconstructionpermitsaneasyassemblydirectlyonthe
DINrailoftheelctriccabinet.Bytheuseoftwoselectors
itispossibletoeasilycongurealltheparameterswithout
theneedofspecialtoolsorprogrammingdevices.
A4digitleddisplayshowsallthenecessariesinformations.

7. Ifyoudonotwanttosavethenewsettingsyouhavejustmodied,youmustdisconnecttheDriverfromthepowersupply
 beforetheendofthe100secondstorestoreprecioussettings.
8. Aftersavingparameterstomemory,thedecimalpointwillbeashingandtheDriverdisplaywillbebackshowingeither
