2.1 General description
InteliLite 9 Family controllers are comprehensive gen-set controllers for single gen-sets operating in stand-by
(MRS) or back-up (AMF) applications. A modular construction allows upgrades to different levels of complexity
in order to provide the best solution for various customer applications. The controllers are equipped with a
powerful graphic display showing icons, symbols and bar graphs for intuitive operation, which, together with its
high level of functionality, sets new standards in Gen-set controls.
2.1.1 The key features of InteliLite 9
Easy-to-use operation and installation. The factory default configuration covers most applications
Various customizations are possible thanks to its configurability
Excellent remote communication capabilities
High level of support for EFI engines (most world producers)
High reliability
2.2 True RMS measurement
This controller measures AC values based on True RMS principle. This principle corresponds exactly to the
physical definition of alternating voltage effective values. Under normal circumstances the mains voltage
should have a pure sinusoidal waveform. However some nonlinear elements connected to the mains produce
harmonic waveforms with frequencies of multiplies of the basic mains frequency and this may result in
deformation of the voltage waveforms. The True RMS measurement gives accurate readings of effective values
not only for pure sinusoidal waveforms, but also for deformed waveforms.
Note: The harmonic deformation causes that the Power Factor of a generator working parallel with the mains
cannot reach values in a certain range around the PF 1.00. The higher the deformation, the wider the power
factor dead range. If the requested power factor is adjusted inside the dead range, the controller cannot reach
the requested value because of this fact.
2.3 Configurability and monitoring
One of the key features of the controller is the system’s high level of adaptability to the needs of each individual
application and wide possibilities for monitoring. This can be achieved by configuring and using the powerful
PC/mobile tools.
