CoilPath ile elektrik kumanda devrelerini çizer, simülasyonda çalıştırır ve görevlerle öğrenirsin. Elektrik teknisyenleri, elektrik-elektronik öğrencileri ve kumanda panosuyla çalışan herkes için hazırlandı. Şema çiz • IEC sembolleriyle güç ve kumanda devresi çiz: sigorta, kontaktör, termik, buton, zaman rölesi, faz koruma rölesi, seviye rölesi, sensörler, motorlar. • Gerçek cihaz görünümleriyle görsel bağlantı çiz; teller cihazların vidalarına bağlanır. • Semboller hizaya gelince kendiliğinden bağlanır. Projelerin cihazında saklanır. Simülasyonda çalıştır • Sigortaları kapat, butonlara bas: kontaktörlerin çekmesini, akımın geçtiği yolu ve motorun dönüş yönünü anında gör. • Zaman rölesi süre sayar, termik aşırı akımda atar; ölçü aletiyle gerilim ölç. • Şema ile görsel bağlantı arasında geç; simülasyon kaldığı yerden devam eder. Görevlerle öğren • 12 bölümde 153 görev: devreyi çalıştır, eksik elemanı tamamla, arızayı bul. • İpuçları sırayla açılır; görev bitince devrenin nasıl çalıştığı anlatılır. Yıldız topla. Hazır devre kütüphanesi • 49 hazır devre: temel bağlantılar, mühürleme ve ileri-geri, zaman röleli devreler, koruma ve sensörler, yıldız-üçgen ve Dahlander, pompa ve flatör devreleri. • PLC uygulamaları: ladder programında akımın yolunu izle, girişleri ve çıkışları simülasyonda gör. • Frekans sürücüsü uygulamaları: tuş takımı, potansiyometre, ileri-geri. Parametreleri değiştir, hızın nasıl değiştiğini gör. Ayrıca • 7 dil: Türkçe, English, Deutsch, Français, Italiano, Español, Português (Brasil). • İnternet gerekmez, hesap açmadan kullanılır. • Gördüğün hataları ve isteklerini uygulamadaki geri bildirim bölümünden yazabilirsin; yeni sürümler isteklere göre hazırlanıyor.
