Komponen Utama &amp; Prinsip Kerja.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tehnisi harus memahami bahwa mesin es batu komersial bekerja dalam 2 siklus utama yang berputar terus-menerus: <strong>Siklus Pembekuan (Freeze Cycle)<\/strong> dan <strong>Siklus Panen (Harvest Cycle)<\/strong>.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Evaporator Grid (Cetakan Kotak):<\/strong> Dipasang vertikal atau miring. Air dipompa dan dialirkan terus-menerus melewati cetakan yang sangat dingin ini hingga perlahan membeku menjadi kotak-kotak padat.<\/li>\n\n\n\n<li><strong>Water Pump (Pompa Air):<\/strong> Mensirkulasikan air dari bak penampung bawah ke bagian atas cetakan agar air mengalir merata.<\/li>\n\n\n\n<li><strong>Hot Gas Bypass Valve (Solenoid Valve Defrost):<\/strong> Katup elektronik yang mengalihkan gas refrigeran panas langsung dari kompresor menuju evaporator (tanpa lewat kondensor) untuk menghangatkan cetakan sesaat agar es batu terlepas saat sudah matang.<\/li>\n\n\n\n<li><strong>Ice Thickness Sensor (Sensor Ketebalan Es):<\/strong> Sensor mekanis atau elektronik di depan cetakan. Jika es sudah tebal dan menyentuh sensor, mesin akan berpindah otomatis dari mode <em>Freeze<\/em> ke mode <em>Harvest<\/em>.<\/li>\n\n\n\n<li><strong>Curtain Switch (Sakelar Tirai):<\/strong> Magnetik sakelar pada tirai penutup cetakan. Saat es jatuh menembus tirai menuju bak penyimpanan (<em>bin<\/em>), tirai terbuka sesaat dan memberi tahu mesin untuk memulai siklus pembekuan baru.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p class=\"wp-block-paragraph\">2. Penjelasan Wiring Diagram Kelistrikan (Control Sequence)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Rangkaian kontrol pada mesin es batu diatur oleh <strong>Main PCB Controller<\/strong> atau kombinasi <strong>Timer Cam\/Relay<\/strong>. Berikut adalah alur kelistrikannya yang wajib dipahami teknisi:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A. Rangkaian Daya (Power Circuit)<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Menggunakan pengaman <strong>MCB<\/strong> dan <strong>ELCB<\/strong> karena unit ini menggabungkan jalur air mengalir dan kelistrikan tegangan tinggi (AC 220V).<\/li>\n\n\n\n<li><strong>Kompresor<\/strong> dan <strong>Motor Kipas Kondensor<\/strong> terhubung ke jala-jala listrik melalui relai daya utama. Kompresor umumnya bekerja terus-menerus baik saat pembekuan maupun pemanenan.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">B. Rangkaian Kontrol Siklus (Sequence Control)<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Siklus Awal (Water Fill):<\/strong> Saat pertama dinyalakan, <em>Inlet Water Valve<\/em> (Solenoid Air) mendapat arus listrik untuk mengisi bak penampung air hingga penuh (dibatasi oleh <em>Water Level Sensor<\/em>).<\/li>\n\n\n\n<li><strong>Siklus Pembekuan (Freeze Cycle):<\/strong>\n<ul class=\"wp-block-list\">\n<li><em>Controller<\/em> menghidupkan <strong>Kompresor<\/strong>, <strong>Kipas Kondensor<\/strong>, dan <strong>Water Pump<\/strong>.<\/li>\n\n\n\n<li>Air dingin dipompa mengalir melewati cetakan evaporator yang mulai membeku.<\/li>\n\n\n\n<li><em>Interlock Safety:<\/em> Pompa air harus terus menyala. Jika pompa mati saat kompresor jalan, air di bak akan membeku total menjadi balok es padat (<em>freeze-up<\/em>).<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Siklus Pemanenan (Harvest Cycle):<\/strong>\n<ul class=\"wp-block-list\">\n<li>Begitu es menebal dan menyentuh <strong>Ice Thickness Sensor<\/strong>, sensor mengirim sinyal ke <em>Controller<\/em>.<\/li>\n\n\n\n<li><em>Controller<\/em> memutus arus ke <strong>Water Pump<\/strong> (pompa berhenti) dan <strong>Kipas Kondensor<\/strong> (kipas mati agar tekanan panas naik).<\/li>\n\n\n\n<li><em>Controller<\/em> mengirim arus 220V untuk membuka <strong>Hot Gas Bypass Valve<\/strong>. Gas panas masuk ke evaporator, membuat permukaan cetakan hangat, dan cetakan kotak es meluncur jatuh ke bawah.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Reset Siklus:<\/strong> Es yang jatuh menyenggol tirai pelindung. <strong>Curtain Switch<\/strong> mendeteksi tirai terbuka lalu menutup kembali. Sinyal ini mereset <em>Controller<\/em> untuk menutup <em>Hot Gas Valve<\/em> dan menghidupkan kembali pompa air untuk memulai pembekuan berikutnya.<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p class=\"wp-block-paragraph\">3.
