It monitors engine parameters, controls the start\/stop sequence, protects the engine from abnormal conditions, and manages automatic mains failure (AMF) operations.<\/p>\n<h2>Key Functions<\/h2>\n<h3>1. Engine Monitoring<\/h3>\n<p>The controller continuously monitors:<\/p>\n<ul>\n<li>Engine speed (RPM)<\/li>\n<li>Oil pressure<\/li>\n<li>Coolant temperature<\/li>\n<li>Generator voltage and frequency<\/li>\n<li>Load current<\/li>\n<li>Fuel level (if sensor installed)<\/li>\n<li>Running hours<\/li>\n<\/ul>\n<h3>2. Start\/Stop Control<\/h3>\n<p>Controllers manage the entire start sequence: pre-heat, crank, detect running, and transition to load. The stop sequence includes cool-down running before shutdown.<\/p>\n<h3>3. Protection<\/h3>\n<p>Automatic shutdown on critical conditions:<\/p>\n<ul>\n<li>Low oil pressure<\/li>\n<li>High coolant temperature<\/li>\n<li>Over-speed<\/li>\n<li>Under-speed<\/li>\n<li>Over-voltage \/ under-voltage<\/li>\n<li>Over-frequency \/ under-frequency<\/li>\n<\/ul>\n<h3>4. Automatic Mains Failure (AMF)<\/h3>\n<p>In AMF mode, the controller monitors utility power. When mains fail, it automatically starts the generator and transfers load. When mains return, it transfers back and cools down the generator.<\/p>\n<h2>Major Controller Brands<\/h2>\n<h3>DeepSea Electronics (DSE)<\/h3>\n<p>Industry leader from the UK. Known for reliability and advanced features. Popular models: DSE7320, DSE8610, DSE4520.<\/p>\n<h3>ComAp<\/h3>\n<p>Czech manufacturer with innovative control solutions. Popular models: InteliLite NT, AMF25.<\/p>\n<h3>SmartGen<\/h3>\n<p>Chinese manufacturer offering cost-effective controllers. Popular models: HGM6120, HGM6110.<\/p>\n<h2>Conclusion<\/h2>\n<p>Choosing the right controller depends on your application complexity, budget, and required features. <a href=\"\/controller-parts\/\">Browse our controller range<\/a> or <a href=\"\/contact\/\">contact us for advice<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What Is a Generator  [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[9],"tags":[38,37,36,39],"class_list":["post-77","post","type-post","status-publish","format-standard","hentry","category-maintenance-repair","tag-comap","tag-deepsea","tag-generator-controller","tag-how-it-works"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.8 -
