- Mushure mekunge nhamba yekupedzisira yaiswa, ramba wakabata A2 kusvika "SET" yaratidzwa. Kana iwe uchida kushandura nhamba yekutanga zvakare, usabate A2. Kwechinguva dzvanya uye buritsa A2 uye yekutanga digit inotanga kubwaira zvakare.
- Kana wapedza kurekodha iyo nyowani setpoint ("Set" inoratidzwa), sunungura A2.
- Cherechedzo 1: Inoshanda setpoint renji ndeye 0-100% yekuzara-chiyero kuyerera. Kana kukosha kwearamu kwakaiswa kumusoro kupfuura yakazara-chiyero, iri clamped pachiyero chakazara pakubuda mumenyu iyi.
- Cherechedza 2: Kudzima alarm, isa kukosha kwayo ku zero.
- Cherechedzo 3: Iyo tsvuku ALARM 1 LED inouya kana kuyerera kwakapfuura iyi setpoint. Iyi LED iri munhevedzano nedhiraivha yedhiraivha yeyakakwira-alarm yakavhurika-muunganidzi yakabuda, zvichireva kuti inobuda transistor inoshanda pese kana iyi LED iripo. Mamwe mamodheru haana chero wiring yekunze inobatana nearamu transistor (ona Model Codes).
Mune example, alarm yakakwirira yakanga yagadzirirwa 80.0; saka, iyo dzvuku LED yakabatidzwa kana kuyerera kwasvika 80.1.
Iyo LED inodzima kana ichiyerera <(setpoint - hysteresis). Hysteresis ndeye 5% yehuwandu hwakazara.
