General description

Description of the controller system (with all options)

InteliLite iL-MRS is a comprehensive controller for single generating sets. IL-MRS 15/16 features
extended support of electronic engines.
InteliLite controllers are equipped with a powerful graphic display showing icons, symbols and bar­graphs for intuitive operation, which sets, together with high functionality, new standards in Gen-set
controls.
InteliLite automatically starts the Gen-set, closes the Gen-set C.B. when all conditions are met, then
stops the engine on external signal or by pressing push buttons.
InteliLite provides gas engine support without ventilation.
The key feature of InteliLite is its easy-to-use operation and installation. Predefined configurations for
typical applications are available as well as user-defined configurations for special applications.

iG IOM/PTM module

iG-IOM and iGS-PTM modules are I/O extension modules equipped with 8 binary inputs, 8 binary
outputs, 4 analogue inputs and one analogue output. The module can be used for MRS15/16 only.

 Binary inputs and outputs are configurable the same way like inputs and outputs on iL.
 Analogue inputs are configurable like iL with the limitation that the binary and tristate mode

can not be used on PTM module.

 The protection of analogue IOM/PTM inputs is activated by overcrossing the limits, active only

when the engine is running.

 iG-IOM analogue inputs are resistive (the same parameters like iL) 0 Ω-2,4 kΩ.

The module

IOM is designed for especially VDO resistive sensors.

 iGS-PTM analogue inputs are configurable by jumpers to ranges 0-250Ω, 0-100mV, 0-20mA.

The module can be used especially for Pt100 sensors and current sensors.

Getting started

How to install

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 length >3m.

Power supply

To ensure proper function:
Use min. power supply cable of 1.5mm

2

Maximum continuous DC power supply voltage is 36VDC. Maximum allowable power supply voltage
is 39VCD. The InteliLite’s power supply terminals are protected against large pulse power
disturbances. When there is a potential risk of the controller being subjected to conditions outside its
capabilities, an outside protection devise should be used.

Hint:

The InteliLite 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 12VDC power supply, the InteliLite includes internal capacitors that allow the
controller to continue operation during cranking if the battery voltage dip occurs. If the voltage before
dip is 10V, after 50ms the voltage recovers to 7 V, the controller continues operating. During this
voltage dip the controller screen backlight can turn off and on but the controller keeps operating.
It is possible to further support the controller by connecting the external capacitor and separating
diode:

IL-MRS-2.2.pdf

Power supply fusing

A one-amp 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 number of connected devices and wire length.
Recommended fuse (not fast) type - T1A. Not fast due to internal capacitors charging during power
up.

Analog inputs are designed for resistive sensors with resistance in range of 0Ω to 2,4kΩ.
To ensure a proper function use shielded cables, especially for length over >3m.

Current output transducers

IL-CU analog inputs are mainly designed for resistor sensors.

In special case transducers to 4-20mA output can be used for oil measuring (10.0Bar or 6.0Bar). Use
predefined 4-20mA/100 or 4-20mA/60 sensors.

This method reduces the input resolution by less than 50%. Some types of transducers are not

suitable for connection to InteliLite analog inputs because of influencing by InteliLite analog input.

As binary input

Open, close state are detected, threshold level is 750 Ω.

As three state input

Open, close and failure state are detected. Threshold level is 750 Ω, failure is detected when circuit
resistance is <10 Ω or > 2400 Ω.

in Engine protection group.
Each Analog input has separate triplet of setpoints: Wrn level, Sd level, Anl Inp del. Names of these

setpoints are fix defined

Number of decimal points of Wrn level1 and Sd level is the same as the configured number of

decimal points of measured value.

Connection rules

CAN bus line must be connected in series, from one unit to the next (no star, no cable stubs, no
branches) both ends must by the 120-ohm (internal or external) resistor terminated. Maximal CAN bus
length is up to 200 meters.

For CAN data cables details see chapter Technical data – Communication interface. CAN cable
shielding connect to IL-CU COM terminal.

IL-CU contains internal fix 120-ohm resistor and must be located on the CAN bus end.

New IG-IOM and IGS-PTM units contain internal jumper removable 120-ohm resistor (in older IOM
types are fix resistors). To be sure check resistor presence by ohmmeter. Unit with internal resistor
connect to the end of CAN line.

Following connections are supported (IOM, PTM, ECU order is not important).

IL-CU – IG-IOM
IL-CU – IGS-PTM
IL-CU – IGL-RA15
IL-CU – IG-IOM – IGL-RA15
IL-CU – IGS-PTM – IGL-RA15

It is possible to connect only one IG-IOM or IGS-PTM and one IGL-RA15 to IL-CU.

Inputs and outputs

Hint:

Any Binary input or output can be configured to any IL-CU controller terminal or changed to different
function by LiteEdit software. There is fix 1 sec delay when any binary input is configured as
protection.

Binary inputs IL-CU - default

BI1 Rem ote Start/stop
BI2 Access lock
BI3 Emergency stop
BI4 Rem ote OFF
BI5 Sprinkler
BI6 Not used

Binary inputs – list

Not used

Binary input has no function. Use this configuration when Binary input is not connected.

Alarm

If the input is closed (or opened) selected alarm is activated.
Binary Alarm configuration items

Name 14 chararcters ASCII string

NC Normally closed Contact type
NO Normally opened
Warning Alarm type

Shut down
All the time Alarm active
Engine running only

Rem start/stop

External request for engine run. AUT mode only.

Emergency stop

If the input is opened, shut down is immediately activated. Input is inverted (normally closed) in default
configuration.

Hint:

In case of controller hardware or software fail, safe stop of the engine doesn’t have to be ensured. To
back-up the Emergency stop function it is recommended to connect separate circuit for disconnection
of Fuel solenoid and Starter signals.

Sprinkler

If the input is closed all alarms are disabled except the binary input EMERGENCY STOP and "engine
overspeed protection".
