Instruction book, IQAN- Lx
The IQAN-Lx control signals
The IQAN-Lx is used to control the object in two or three directions:
• the lever is moved to the right/left, direction X +/-.
• the lever is moved forwards/back, direction Y +/-.
• the rocker is moved upwards/downwards, direction Z +/-.
The control signal is proportional to the lever's working range.
The control signal is transferred internally from the IQAN-Lx via the CAN bus to the
master unit. The control signal's data is treated in the system and is then available as an
output signal, for example in the expansion unit IQAN-XT2. The IQAN-Lx can be
equipped with a proportional rocker ("G" handle option for -LL, "D" handle option for
-LM), or with buttons ("N" or "E" handle option for -LL ).
The following descriptions refer to a fully equipped lever, but is also applicable to the
functions on levers with no rocker or buttons.
The IQAN-Lx are delivered with an outgoing cable that has 2 connectors for all inputs
and outputs.

Instruction book, IQAN- Lx
There are five (5) digital inputs in the C2 connector for external signals..
The IQAN-Lx module has two (2) voltage inputs VIN-A and VIN-B for connection of
0-5 Vdc signals. These inputs can be configured as digital inputs with IQANdesign
software for reading switches. Voltage inputs and digital inputs share positions, see
below.
Outputs
An IQAN-Lx may have 2 or 3 proportional lever directions, XY or XYZ.
There is one (1) digital output, DOUT-A This output can also be configured as a digital
input with IQAN software. Digital output and digital input share positions, see below.
The digital output, DOUT-A may be activated when there is an error message for the
system, such as a short-circuit and input or output interruption. By connecting the
digital output to a warning lamp or audio signal, the driver is alerted that an error
message has been given.
Connection of DOUT
Connect the alarm (audio signal) between pin C2:6 and -BAT (the battery’s negative
pole). See the illustration below. An active output gives battery voltage (11-32 Vdc) to
the pin. The maximum load is 200 mA.
Connection of DOUT as an alarm output.
CAN related functions
The master unit uses a CAN-bus (CAN = Controller Area Network) to communicate
with the IQAN-Lx module. The CAN-bus is a robust communication protocol that is
widely used and well proven within the automotive industry.

Instruction book, IQAN- Lx
4Safety
General
In order to fulfil high safety demands, the Lx module uses a real-time operating system
for fault tolerant embedded systems. The Lx module has an internal watchdog function.
If the watchdog detects any software errors, necessary precautions will be activated.
Polarity reversal
The Lx module is protected against power supply polarity reversal, provided an
external fuse, max 3A (Fast) is being used. Polarity reversal can damage the unit if the
fuse is not used.
CAN-bus interruption
The Lx module has special safety functions if the CAN-bus is interrupted. Each module
checks for any interruptions in the CAN-bus communication. If an error occurs the
master will present a related message on the display. The Lx module will also indicate
the error with an error code ref., see page 9.
Input/ output Protection
All inputs on the Lx module are designed to withstand the maximum specified supply
voltage. The outputs are protected against short circuit. Furthermore, an error on one
input or the output will not influence other inputs.
System Diagnostics
The yellow blinking LED on the module indicates normal status. If there is an error
detected, the master will present a message on the display. The Lx module also
indicates error status through the red blinking LED as shown below.
This gives an immediate diagnosis as to the nature of the error that has occurred.
The location of the LED indicators on the IQAN-Lx module.
The green LED indicates power on. The yellow/red LED will be blinking red when an
error has been detected. To get futher information about the error messages, see

Mounting the unit
NOTICE
The IQAN-Lx unit should be mounted according to the following instructions.
Mounting considerations
• The control lever must be built in so that it is protected against damp, dirt and
mechanical damage.
• The machine manufacturer must consider the need of a protective catch, or similar,
to prevent unintentional working of the lever
NOTICE
Take careful consideration when positioning the unit.
• Mount the unit so that it is not exposed to external heat, e.g. from the engine or
heater
• Mount the unit so that the LEDs are visible
• Mount the unit so there is no risk that the harness can be folded, crushed, worn or
damaged in any way
• Locate the harness so there is no pressure on the connector.
• Use ergonomics. The control lever should be mounted at a height so that there is no
pressure on the driver's arm and shoulders. IQAN-LM should be mounted at an
angle so that the driver's wrist is held normally. The IQAN-LL combined with
moveable arm rests can provide good ergonomics.
Always consider ergonomics when installing hand controls.
• The control lever IQAN-LM with 3rd axis is intended to be positioned so that the

Instruction book, IQAN- Lx
IQAN-Lx addressing/terminating
Addressing
Each Lx module will have a specific address, enabling the master module to
communicate with the modules through the CAN-bus. When operating, the system
distinguishes between different modules by first verifying the module type and
secondly, through the modules having unique addresses.
The maximum number of similar modules in a system is four or eight depending on the
master module, denoted in the first case as addresses 0, 1, 2, 3 respectively. In order to
assign any Lx module a unique CAN-address, an ID-Tag will have to be connected to
the positions ADDR-H and ADDR-L.
Connecting of Id-Tag in Lx connector.
Terminating
To eliminate interference in the communication, through the CAN-bus, the CAN-bus
must be terminated. Because the master module always is located at the beginning of
the bus, the master is provided with an internal termination.
You will only need to terminate the end of the bus.
If an IQAN-Lx is located at the end of the CAN-bus then use an ID-tag having a
combined address and terminating function. This is denoted with a "T" for terminating,
after the appropriate address such as; 0T, 1T, 2T...
Selecting appropriate Id-Tag
• Check the address number of the module.
• If the module is located at the end of the CAN-bus then select the appropriate ID-
Tag denoted with a "T".
NOTICE
The CAN-bus must not be terminated using an external regular terminating resistor,
due to the fact that terminating is made from within the Lx module in conjunction with
the installed ID-Tag.
EXAMPLE
If having an IQAN-Lx module with address 0, the system will denote this
one as Lx-A0, The letter "A" refers to CAN-bus A.
