  • Part Number:398-0940 3980940
  • It is mainly used to warm up the engine in cold environments to ensure smooth engine starting and reduce mechanical wear.
  • Function: 1. Engine preheating: under low temperature conditions, the preheating relay controls the preheating circuit to heat up the gas in the engine cylinder, facilitating normal engine starting. 2. Extend engine life: reduce the wear and tear of the engine during cold start by preheating, and extend the life of the engine.
  • Principle of operation: 1. Signal reception: the preheat relay receives the start signal from the key switch or control panel. 2. Preheating control: according to the preset program, control the preheating circuit on and off to preheat the engine. 3. Starting the engine: After the preheating is completed, the preheating relay disconnects the preheating circuit and allows the engine to start.
  • Precautions: 1. Suitability: Ensure that the selected preheat relay is compatible with the excavator model and electrical system. 2. Operating environment: Consider the operating temperature range of the excavator and select a preheat relay with a suitable operating temperature range.
