Eksperimental muammolarni bartaraf etishning umumiy usullari yuqori haroratli elektr pechlari

1. Ishga tushganda displey yo’q va quvvat indikatori yonmaydi: elektr uzatish liniyasining buzilmaganligini tekshiring; asbobning orqa tarafidagi oqish va o’chirgichni ushlab turuvchi kalit “yoqilgan” holatidami; sug’urta yonishi mumkinmi.

2 .Continuous alarm at power-on: Press the “Start-in” button in the initial state. If the temperature is greater than 1000°C, the thermocouple is disconnected. Check whether the thermocouple is intact and whether the wiring is in good contact.

3. Eksperimental testga kirgandan so’ng, paneldagi “isitish” indikatori yonadi, lekin harorat ko’tarilmaydi: qattiq holat rölesini tekshiring.

4. Asbobning quvvatini yoqqandan so’ng, isitish indikatori eksperimental bo’lmagan holatda o’chirilgan bo’lsa, vaqti-vaqti bilan o’choq harorati ko’tariladi: o’choq simining har ikki uchida kuchlanishni o’lchang. Agar 220V AC kuchlanish mavjud bo’lsa, qattiq holat rölesi shikastlangan. Xuddi shu modelga o’zgartiring.
