Features:The Engine Interface Module is a sealed, engine mounted module that provides switching relays for the Starter Motor Solenoid, Glow Plug and Fuel Solenoid. Each of these circuits is protected with individual fuses mounted in the module. Individual LED's illuminate when each circuit is energised. There are two versions of the Engine Interface Module available: EIM Basic: The ElM is utilised in conjunction with control panels equipped with overspeed shutdown. EIM Plus: The ElIM plus is used in conjunction with control panels not equipped with overspeed shutdown. Overspeed Signal (EIM Plus only) The ElM Plus monitors the speed signal from the magnetic pick-up. If the engine speed rises above a certain pre-setable value, the module sends a zero volt signal to the generator set control panel to activate the Overspeed Fault circuitry. The Overspeed Set Point is factory set at 55 Hz for 50 Hz sets and 66 Hz for 60 Hz sets. This can be adjusted using the adjustment screw accessed through the hole beside the Overspeed Set-up LED. While the engine is running at the rated speed (1500 rpm for 50 Hz or 1800rpm for 60 Hz) the adjustment screw should be adjusted until the Overspeed Set-up LED just goes out. This sets the overspeed value at 10% above the speed at which the generator set is operating.
