1 Introduction
Instruction book, IQAN- MD3
1 Introduction
These instructions are to be used as a reference tool for the vehicle manufacturer’s
design, production, and service personnel.
The user of these instructions should have basic knowledge in the handling of
electronic equipment.
Safety symbols
Sections regarding safety, marked with a symbol in the left margin, must be read and
understood by everyone using the system, carrying out service work or making changes
to hardware and software.
The different safety levels used in this manual are defined below.

situation exists. If precautions are not taken, this could result in death, serious injury or
major property damage.
CAUTION
Sections marked with a caution symbol in the left margin, indicate that a potentially
hazardous situation exists. If precautions are not taken, this could result in minor injury
or property damage.
NOTICE
Sections marked with a notice symbol in the left margin, indicate there is important
information about the product. Ignoring this could result in damage to the product.

2 Precautions
General safety regulations
Work on the hydraulics control electronics may only be carried out by trained
personnel who are well-acquainted with the control system, the machine and its safety
regulations.
WARNING
Mounting, modification, repair and maintenance must be carried out in accordance
with the manufacturer's regulations. The manufacturer has no responsibility for any
accidents caused by incorrectly mounted or incorrectly maintained equipment. The
manufacturer does not assume any responsibility for the system being incorrectly
applied, or the system being programmed in a manner that jeopardizes safety.
WARNING
Damaged product may not be used. If the control system shows error functions or if
electronic modules, cabling or connectors are damaged, the system shall not be used.
WARNING
Electronic control systems in an inappropriate installation and in combination with
strong electromagnetic interference fields can, in extreme cases, cause an unintentional
change of speed of the output function.
NOTICE
As much as possible of the welding work on the chassis should be done before the
installation of the system. If welding has to be done afterwards, the electrical
connections on the system must be disconnected from other equipment. The negative
cable must always be disconnected from the battery before disconnecting the positive
cable. The ground wire of the welder shall be positioned as close as possible to the
place of the welding. The cables on the welding unit shall never be placed near the
electrical wires of the control system.
Construction regulations
CAUTION
The vehicle must be equipped with an emergency stop which disconnects the supply
voltage to the control system's electrical units. The emergency stop must be easily
accessible to the operator. The machine must be built if possible, so that the supply
voltage to the control system's electrical units is disconnected when the operator leaves
the operator’s station.
Safety during installation
CAUTION
Incorrectly positioned or mounted cablingcan be influenced by radio signals which can
interfere with the functions of the system.

Safety during start-up
WARNING
The machine's engine must not be started before the control system is mounted and its
electrical functions have been verified.
Ensure that no one is in front, behind or nearby the machine when first starting up the
machine.
Follow the instructions for function control in the Start-up section.
Safety during maintenance and fault diagnosis
CAUTION
Ensure that the following requirements are fulfilled before any work is carried out on
the hydraulics control electronics.
• The machine cannot start moving.
• Functions are positioned safely.
• The machine is turned off.
• The hydraulic system is relieved from any pressure.
• Supply voltage to the control electronics is disconnected.

3 Product description
IQAN-MD3
IQAN-MD3 is a combined display and bus master capable of running applications
created by IQANdesign. Built on a 32-bit platform the unit has large computational
power and is capable of controlling large applications.
The IQAN-MD3 module.
System overview
The master module, IQAN-MD3, is the central unit in the system. IQAN-MD3 has
three CAN buses. Two buses support ICP and are able to control expansion units such
as XA2, XS2, XT2, Lx and XR. SAE J1939 and Generic CAN are also supported on
the CAN buses and gives the possibility to interface to 3rd party units. A third CAN
bus is available for diagnostic purposes.
"Soft" function buttons and control buttons in combination with a graphical display
makes system feedback with user interaction possible. The display in the module has
very high optical performance across a wide operating temperature range and over a
wide range of ambient light.
IQAN-MD3 has voltage and digital inputs that are designed to be flexibly configured
using IQANdesign software. The unit also has a low power digital output.
All I/O are EMI filtered and protected against short circuit to -BAT and +BAT.

I/O overview
Inputs/Outputs
The IQAN-MD3 module has seven (7) voltage inputs VIN-A thru VIN-G for
connection of 0-5 Vdc signals. These inputs can be configured as digital inputs for
reading switches. Voltage inputs and digital inputs share positions, see below.
There is a digital output, DOUT-A, on IQAN-MD3 that 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.
Connect the alarm (audio signal) between pin C2:12 and ground (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 IQAN-MD3 uses three CAN-buses (CAN = Controller Area Network) to
communicate with IQAN expansion modules, other systems and diagnostics.

Display
Brightness
The brightness is easily adjusted by pressing the ’menu’ button and following the
prompts to the backlight settings section.
Burn-in
The IQAN-MD3 TFT display, like other computer screens can have a ghost picture
occur if a static image is left on the display for extended periods of time. For the best
viewing over the life of the product we recommend using the screensaver functionality.
NOTICE
To avoid burn-in, use the screensaver on the display.
Maintenance
The 3.5" transflective display is a high quality viewing interface and reasonable care
should be taken to maintain it.
The display can be cleaned with an LCD cleaning solution found in many stores. Use a
lightly dampened lint-free, non-abrasive cloth when cleaning the display.
NOTICE
To avoid scratches, do not wipe or clean a dry display.
Environment Specification
IQAN-MD3 is a hardened module suitable for outdoor use. However, concentrating
cleaning jets on the control surface of the IQAN-MD3 can cause a degradation of the
finishing and should be avoided.
NOTICE
To keep the unit’s buttons looking their best, do not blast the control surface with
cleaning jets.
Back of unit
If the rear surface of the IQAN-MD3 unit is exposed and will be subjected to high
pressure steam cleaning, care should be taken around the connector assemblies. The
Deutsch DTM connectors are IP67 rated which is suitable for any type of outdoor
conditions. However, concentrating the cleaning jets on the connectors of the IQAN-
MD3 can cause damage to the connector seals or wire insulation and should be
avoided. Use of shielding is recommended to block high pressure cleaning jets, if the
rear of the unit is exposed.
NOTICE
To avoid damaging the connector seals or wire insulation, do not blast the connectors
with cleaning jets.
