Pada sistem pabrikasi model dahulu, kontrol mesin tidak menggunakan PLC (Programmable Logic Controller), melainkan mengandalkan sistem logika relai konvensional (Relay Logic Control)<\/strong>. Sistem ini sepenuhnya menggunakan kombinasi komponen elektromekanis seperti kontaktor magnetik, relai kontrol, tombol tekan (push button<\/em>), dan pengaman termal.<\/p>\n\n\n\n

Sebagai contoh konkret yang paling sering digunakan pada pabrikasi model dahulu, berikut adalah Wiring Diagram Konvensional untuk Rangkaian DOL (Direct On Line) Starter dengan Sistem Pengunci (Latch\/Self-Holding)<\/strong>. Rangkaian ini biasanya digunakan untuk menyalakan dan mematikan motor 3-Fasa pada mesin pabrik (seperti konveyor, pompa, atau mesin bubut lama).<\/p>\n\n\n\n

1. Komponen yang Dibutuhkan<\/h2>\n\n\n\n
    \n
  • MCB 3-Phase<\/strong>: Pengaman arus hubung singkat untuk jalur daya motor.<\/li>\n\n\n\n
  • MCB 1-Phase<\/strong>: Pengaman untuk jalur kontrol\/kendali.<\/li>\n\n\n\n
  • Kontaktor Magnetik (K1)<\/strong>: Sakelar elektromekanis utama untuk menyalurkan listrik ke motor. Memiliki kontak utama (NO) dan kontak bantu (auxiliary contact<\/em> NO\/NC).<\/li>\n\n\n\n
  • Thermal Overload Relay (TOR)<\/strong>: Pengaman motor dari beban lebih (overheat).<\/li>\n\n\n\n
  • Push Button STOP (NC)<\/strong>: Tombol darurat\/berwarna merah untuk mematikan mesin.<\/li>\n\n\n\n
  • Push Button START (NO)<\/strong>: Tombol berwarna hijau untuk menyalakan mesin.<\/li>\n\n\n\n
  • Motor 3-Fasa<\/strong>: Beban utama (mesin pabrik).<\/li>\n<\/ul>\n\n\n\n
    \n\n\n\n

    2. Deskripsi Pengabelan (Wiring Description)<\/h2>\n\n\n\n

    Rangkaian dibagi menjadi dua bagian utama khas model dahulu: Rangkaian Daya (Power)<\/strong> dan Rangkaian Kontrol (Control)<\/strong>.<\/p>\n\n\n\n

    A. Rangkaian Daya (Mengalirkan Arus Besar ke Motor)<\/strong><\/h2>\n\n\n\n
      \n
    1. Hubungkan sumber listrik 3 Fasa (R, S, T<\/strong>) ke bagian atas (input) MCB 3-Phase<\/strong>.<\/li>\n\n\n\n
    2. Dari output MCB 3-Phase, hubungkan kabel ke kontak utama Kontaktor (K1)<\/strong> pada terminal 1\/L1, 3\/L2, dan 5\/L3<\/strong>.<\/li>\n\n\n\n
    3. Di bagian bawah kontaktor (output terminal 2\/T1, 4\/T2, 6\/T3<\/strong>), pasang\/hubungkan langsung ke pin input Thermal Overload Relay (TOR)<\/strong>.<\/li>\n\n\n\n
    4. Dari terminal output TOR (2\/T1, 4\/T2, 6\/T3<\/strong>), hubungkan kabel langsung menuju terminal gulungan Motor 3-Fasa (U, V, W)<\/strong>.<\/li>\n<\/ol>\n\n\n\n

      B. Rangkaian Kontrol (Sistem Logika Pengendali)<\/strong><\/h2>\n\n\n\n

      Sistem ini menggunakan tegangan 1-fasa (220V). Mari kita urutkan jalurnya secara seri dan paralel:<\/p>\n\n\n\n

        \n
      1. Jalur Utama:<\/strong> Ambil salah satu fasa (misalnya Fasa R<\/strong>) menuju input MCB 1-Phase<\/strong>.<\/li>\n\n\n\n
      2. Pengaman TOR:<\/strong> Dari output MCB 1-Phase, hubungkan kabel ke kontak bantu NC milik TOR (Terminal nomor 95)<\/strong>. Kemudian dari output TOR (Terminal nomor 96)<\/strong>, teruskan kabel menuju input Push Button STOP<\/strong>.<\/li>\n\n\n\n
      3. Tombol STOP ke START:<\/strong> Dari output Push Button STOP<\/strong>, hubungkan kabel ke input Push Button START<\/strong>.<\/li>\n\n\n\n
      4. Sistem Pengunci (Latch) Konvensional:<\/strong> Agar mesin tetap menyala saat tombol START dilepas, kita harus memasang kontaktor bantu secara paralel.\n
          \n
        • Tarik kabel dari input Push Button START menuju Kontak Bantu NO milik Kontaktor K1 (Terminal nomor 13)<\/strong>.<\/li>\n\n\n\n
        • Tarik kabel dari output Push Button START menuju Kontak Bantu NO milik Kontaktor K1 (Terminal nomor 14)<\/strong>.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
        • Menuju Koil:<\/strong> Dari output Push Button START (atau dari terminal NO 14 tadi), hubungkan kabel ke koil kontaktor K1 (Terminal A1)<\/strong>.<\/li>\n\n\n\n
        • Jalur Netral:<\/strong> Hubungkan langsung kabel Netral (N)<\/strong> dari sumber listrik menuju koil kontaktor K1 (Terminal A2)<\/strong>.<\/li>\n<\/ol>\n\n\n\n
          \n\n\n\n

          3. Cara Kerja Rangkaian Ini<\/h2>\n\n\n\n
            \n
          • Kondisi Awal:<\/strong> Saat MCB dinyalakan, arus tertahan di Push Button START dan Kontak NO 13-14 Kontaktor. Motor masih mati.<\/li>\n\n\n\n
          • Saat Tombol START Ditekan:<\/strong> Arus mengalir menuju Koil A1. Kontaktor K1 menjadi magnet, menarik semua sakelar di dalamnya. Kontak daya menutup (motor menyala) dan Kontak Bantu NO (13-14) menutup.<\/li>\n\n\n\n
          • Sistem Pengunci Aktif:<\/strong> Saat Anda melepas tekanan dari tombol START, arus listrik sekarang berputar mengalir melewati Kontak Bantu NO (13-14) yang sudah menutup tadi. Ini membuat koil tetap mendapat setrum (terkunci).<\/li>\n\n\n\n
          • Saat Tombol STOP Ditekan:<\/strong> Jalur kontrol terputus, kemagnetan kontaktor hilang, sakelar kembali terbuka, dan motor berhenti total.<\/li>\n\n\n\n
          • Saat Beban Lebih (Overload):<\/strong> Jika motor terlalu panas, mekanisme bimetal di TOR akan memicu kontak 95-96 terbuka secara mekanis, sehingga memutus seluruh sistem kontrol demi keamanan.<\/li>\n<\/ul>\n\n\n\n
