1.4.3 Dangerous voltage
In no case touch the terminals forvoltage andcurrent measurement!
Always connect grounding terminals!
In any case do not disconnect controller CT terminals!
1.4.4 Adjust the setpoints
All parameters are adjusted to theirtypical values. Howeverthe setpoints has to be checked andadjusted to
their real values before the first starting of the gen-set.
IMPORTANT: Wrong adjustment of setpoints can destroy the gen-set.
Note: The controller contains a large number of configurable setpoints, because of this it is impossible to
describe all of its functions. Some functions can be changed or have different behavior in different SW versions.
Always check the Global guide and New feature list for SW version which is used in controller. This manual
only describes the product and is not guaranteed to be set for your application.

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
highlevel 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 alternatingvoltage effective values. Undernormal circumstances themains voltage
should have a pure sinusoidal waveform. However some nonlinearelements 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 puresinusoidal waveforms, but also fordeformed 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
Oneof 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 thepowerful
PC/mobile tools.
InteliLite9 Global Guide
11
2.3.1 Supported configuration and monitoring tools
InteliConfig - complete configuration and single gen-set monitoring
WinScope - special graphical monitoring software
Note: Use the InteliConfig PC software to read, view and modify configuration from the controller or disk and
write the new configuration to the controller or disk.
The firmware of controller contains a large number of binary inputs and outputs needed forall necessary
functions available. However, not all functions are required at thesame time on thesame gen-set and also the
controller hardware does not have so many input and output terminals. One of the main tasks of the
configuration is mapping of “logical” firmware inputs and outputs to the “physical” hardware inputs and outputs.
2.3.2 Configuration parts
Mapping of logical binary inputs (functions) or assigning alarms to physical binary input terminals
Mapping of logical binary outputs (functions) to physical binary output terminals
Assigning sensor characteristics (curves) and alarms to analoginputs
Selection of peripheral modules, which are connected to the controller, and doing the same (as mentioned
above) for them
Selection of ECU type, if an ECU is connected
Changing the languageof the controller interface
Image 2.1 Principle of binary inputs and outputs configuration
The controller is shipped with a default configuration, which should be suitable for most standard applications.
This default configurationcan be changed only by using a PC with theInteliConfig software. See InteliConfig
documentation for details.
InteliLite9 Global Guide
12
Once theconfiguration is modified, it canbe saved to a file for later usage with anothercontroller or for backup
purposes. The file is called archive and has the file extension .ail3. An archive contains a full image of the
controller at the time of saving (if the controller is online for the PC) except the firmware. Besides configuration it
also contains current adjustment of all setpoints, all measured values, a copy of the history log and a copy of the
alarm list.
The archive can be simply used for cloning controllers, i.e. preparingcontrollers with identical configuration and
settings.

4.4.1 General
To ensure proper function:
Use grounding terminals.
Wiring for binary inputs and analog inputs must not be run with power cables.
Analog and binary inputs should use shielded cables, especially when the length is more than 3m.
Tightening torque, allowable wire size and type, for the Field-Wiring Terminals:
Example of used connectors:
For Mains and Generator Voltage, and for
Current terminals:
For other controller field wiring terminals: Use only diameter 2.0–0.5 mm (AWG 12–26)conductor, rated
Specified tightening torque is 0.56N·m (5.0In-lb).
Use copper conductors only.
Use only diameter 2.0–0.5 mm (AWG 12–26)conductor, rated
for 90°C minimum.
for 75°C minimum.
4.4.2 Grounding
The shortest possible length of wire shouldbe used for controller grounding. Use cable min 2.5mm2.
The negative " - " battery terminal must be properly grounded.
Switchboard and engine must be groundedat common point. Use as short cable as possible to the grounding
point.
4.4.3 Power supply
To ensure proper function:
Use power supply cable min. 1.5mm
Maximum continuous DC power supply voltage is 36V DC. The controller’s power supply terminals are
protected against large pulse power disturbances. When thereis a potential risk of the controller being subjected
to conditions outside its capabilities, an outside protection device should be used.
2
It is necessary to ensure that potential difference betweengenerator current COM terminal and battery “- ”
terminal is maximally ± 2V. Therefore is strongly recommended to interconnect these two terminals together.
Note: The controller should be grounded properly in order to protect against lighting strikes. The maximum
allowable current through the controller’s negative terminal is 4A (this is dependent on binary output load).
For the connections with 12 V DC power supply, the controller includes internal capacitors that allow the
controller to continue in operation duringcranking if the batter voltage dip occurs. If the voltage dip goes during
cranking to 0 V and after50 ms it recovers to 4 V, the controller continues operating. This cycle can repeat
several times. Duringthis voltage dip the controller screen backlight canturn off.
InteliLite9 Global Guide
22
Note: Recommended fusing is 3 A fuse.
Note: In case of the dip to 0 V the high-side binary outputs will be temporarily switched off and after recovering
to 4 V back on.
IMPORTANT: When the controller is power up only by USB and the USB is disconnected then the
actual statistics can be lost.
Note: Suitable conductor protection shall be provided in accordance with NFPA 70, Article 240.
Note: Low voltage circuits (35 volts or less) shall be supplied from the engine starting battery or an isolated
secondary circuit.
Note: It is also possible to further support the controller by connecting the external capacitor and separating
diode. The capacitor size depends on required time. It shall be approximately thousands of μF. The capacitor
size should be 5 000μF to withstand 150 ms voltage dip under following conditions: Voltage before dip is 12V,
after 150ms the voltage recovers to min. allowed voltage, i.e. 8V.
Power supply fusing
A 3 A fuse should be connected in-line with the battery positive terminal to the controller and modules. These
items should never be connected directly to the starting battery. Fuse value and type depends on numberof
connected devices and wire length. Recommended fuse (not fast) type - T3 A. Not fast dueto internal
capacitors charging during power up.
Note: Recommended fusing is 3 A fuse.
4.4.4 Measurement wiring
Use 1.5 mm2cables for voltage connection and 2.5 mm2for current transformers connection. Adjust Connection
type (page 147), Nominal Voltage Ph-N (page 149), Nominal Voltage Ph-Ph (page 149), Nominal Current (page
146), PT Ratio (page 149), Vm PT Ratio (page 150) andCT Ratio (page 147) by appropriate setpoints in the Basic

IMPORTANT: Risk of personal injury due to electric shock when manipulating voltage terminals
under voltage. Be sure the terminals are not under voltage before touching them.
Do not open the secondary circuit of current transformers when the primary circuit is closed. Open
the primary circuit first.
CT Location
Image 4.2 CT Location
There are two options of CT location.
a) Load
b) Gen-Set
Note: The current measurement protections are active only when the Gen-set is running.
If the CT Location is set to Load the Short Circuit BOC (page 193) protection is enabled only when GCB is
closed.
Current measurement wiring
The number of CT’s is automatically selected based on selected value of setpoint Connection type (page 147)
[3Ph4Wire/ High Leg D / 3Ph3Wire / Split Ph / Mono Ph].
Generator currents and powermeasurement is suppressed if current level is bellow <1 % of CT range.
To ensure proper function:
Use cables of 2.5 mm
Use transformers to 5 A
Connect CT according to following drawings:
