1,FLAME RETARDANT MATERIAL: Interference interface speed control board is made of excellent material, flame retardant, high temperature resistance, long service life, safe use 2,APPLICABLE SCENARIO: The engine interface module is a sealed module mounted on the engine that provides on off relays for the starter motor solenoid, electric plug, and fuel solenoid valves. Each of these circuits is protected by a separate fuse installed in the module. When each circuit is energized, individual LEDs light up 3,2 VERSIONS OF ENGINE INTERFACE MODULE AVAILABLE: EIM Basic is used with a control panel equipped with overspeed stops EIM Plus is used with a control panel that is not equipped with an overspeed stop 4,HOW IT WORKS: Overdrive signals (EIM Plus only) ElM Plus monitors speed signals from magnetic pickers. If the engine speed rises above a certain preset value, the interface module sends a 0V signal to the generator control panel to activate the overspeed fault circuit 5,EFFICIENT AND PRACTICAL: The overspeed setting points of the engine interface module are set to 55Hz(50Hz unit) and 66Hz(60Hz unit) before delivery. This can be adjusted using the adjustment screw entered through the hole next to the overdrive setting LED. When the engine is running at rated speed (1500rpm for 50Hz or 1800rpm for 60 Hz), adjust the adjustment screw until the overspeed setting LED is off. This sets the overdrive value to 10 percent above the operating speed of the generator set Item Type: Engine Interface Module Material: ABS 1 x Engine Interface Module Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
