Ukudluliselwa kwesikhathiiyithuluzi lokulawula elisebenzisa isimiso sikagesi noma isimiso somshini ukuze kufezwe ukulawula ukubambezeleka kwesikhathi. Inezinhlobo eziningi, njengohlobo lokudambisa umoya, uhlobo lukagesi kanye nohlobo lwe-elekthronikhi. Ukudluliselwa kwesikhathi kungahlukaniswa ngezinhlobo ezimbili: uhlobo lokulibaziseka kwesikhathi olunamandla kanye nohlobo lokulibaziseka kwesikhathi sokuvala ugesi. Ukudluliselwa kwesikhathi okudambisiwe emoyeni kunobubanzi obukhulu bokulibaziseka (0.4 ~ 60s kanye no-0.4 ~ 180s), kulula ngesakhiwo, kodwa akunembile kangako.
Uma ikhoyili inikwe amandla, i-armature nama-pallet kudonswa yi-core bese kuhamba phansi ngokushesha, okwenza ukuthi isenzo sixhumane ngokushesha noma sivalwe. Kodwa induku ye-piston kanye ne-lever akukwazi ukulandela i-armature kanye nokwehla, ngoba ingxenye engenhla yenduku ye-piston ixhunywe kulwelwesi lwerabha ekamelweni lomoya, lapho induku ye-piston ekukhululweni kwentwasahlobo iqala ukuhamba phansi, i-membrane yerabha iyehla igobile, igumbi lomoya elingaphezulu komoya liba lincane futhi induku ye-piston iyamanziswa bese iwela kancane kancane. Ngemva kwesikhathi esithile, induku ye-piston iyehla iye endaweni ethile, izocindezela isenzo sokuxhumana sokubambezeleka nge-lever, ukuze ukuxhumana okuguquguqukayo kucime, ukuxhumana okuguquguqukayo kuvale. Kusukela ku-coil enikwe amandla kuya kokuxhumana kokubambezeleka kwesikhathi ukuze kuqedwe isenzo, lesi sikhathi yisikhathi sokubambezeleka kokudluliselwa. Ubude besikhathi sokubambezeleka bungashintshwa ngokulungisa usayizi wembobo yokungena yegumbi lomoya ngesikulufu. Ngemva kokuba ikhoyili yokuheha isusiwe amandla, i-relay iyalulama ngesenzo sentwasahlobo yokutakula. Umoya ukhishwa ngokushesha ngembobo yokuphuma komoya.
