Iyo inowanzovharwa mhando mhando kana iyo inowanzovhura mhando inogona kusarudzwa zvinoenderana nenguva yekuenderera mberi nguva yekushanda.
1. Iyo inowanzovharwa solenoid vharuvharu iyo isosarudzwa apo iyo solive vharuvharu yekuvharwa kwenguva yakareba, uye nguva yekuvhara yakareba kupfuura iyo nguva yekuvhura, uye nguva yekuvhura inoramba isingagumi.
2. Iyo nguva yakareba yekuvhura uye kuvhara zvese zvinodiwa, wobva wazvikanda {{}}} kudzora mindavha matsime anofanirwa kusarudzwa.
3. Iyo inowanzo kuvhura type yelenoid yakakodzera kumamiriro ezvinhu anofanirwa kuvhurwa kwenguva yakareba, uye nguva yekutanga yakareba kupfuura iyo nguva yekuvhara, uye nguva yekuvhura inoramba iri kure.
4. Iyo inowanzovhura solenoid vharuvhu inoshandiswa mune emergency akacheka Asi, dzimwe nguva, kazhinji yakavhurika vharuvhu tolenoid haigone kusarudzwa, sevheso uye kuongorora moto,
