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 by using the adjustment screw accessed through the hole beside the overspeed set-up LED.
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.
The ElM plus is used in conjunction with control panels not equipped with overspeed shutdown.
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.
If the engine speed rises above a certain pre-setable value, the module sends a 0 volt signal to the generator set control panel to activate the overspeed fault circuitry.
