Mounted at multiple assembly points including the cabin lighting\/emergency stop circuit and control panel console, it manages the relay-switched power pathways that keep lighting, safety shutoffs, and control functions operating correctly.\u003c\/p\u003e\n\n\u003cp\u003eWhen diagnosing relay faults on the E3000, Wacker Neuson service procedures call for measuring coil resistance across terminals 0 and 1, with a passing range of 825 to 1025 ohms. Normally closed contacts (terminals 3 and 4) and normally open contacts (terminals 2 and 4) should each measure approximately 0.1 ohms continuity. A relay that falls outside these values has failed and must be replaced. Symptoms of a failed power relay can include loss of cabin lighting, non-functional emergency stop response, or inoperative control panel functions.\u003c\/p\u003e\n\n\u003cp\u003eCompatible with the following Wacker Neuson models:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eE1250P (E 1250P Hydronic Heater Premium Diesel)\u003c\/li\u003e\n\u003cli\u003eE1250P (E 1250P Hydronic Heater Premium LP NG)\u003c\/li\u003e\n\u003cli\u003eE1250S (E 1250S Hydronic Heater Standard LP NG)\u003c\/li\u003e\n\u003cli\u003eE3000 (5100056440)\u003c\/li\u003e\n\u003cli\u003eE3000 (5100056441)\u003c\/li\u003e\n\u003cli\u003eHSH380S\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eGenuine Wacker Neuson OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Wacker Neuson","offers":[{"title":"Default Title","offer_id":43401260924976,"sku":"WACKER-5200022711","price":70.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/5200022711.jpg?v=1784140874","url":"https:\/\/cce-industries.com\/products\/wacker-neuson-power-relay-5200022711-for-hydronic-heaters","provider":"CCE Industries","version":"1.0","type":"link"}
