Warranty
Kimax 2 Radio is covered by Sense-Tech Weighing Systems ApS guarantee. Electronic failure
and broken components caused by normal use are repaired or exchanged when necessary,
when sent to the factory.
Damage to your vehicle caused by installation of Kimax instruments or loss of time caused by
recalibration or repairments of Kimax instruments are not covered by Sense-Tech Weighing
Systems ApS in any case.
Basic safety rules
Before you start the installation procedure, make sure that the instruments have not suffered
any damage during transport.
Note that the Kimax 2 instruments must be installed and connected in accordance
with the regulations valid for the vehicle and country in question.
The Kimax 2 instruments must be protected from gravel, water spray from wheels
and other factors that may damage the instruments.
We recommend to mount the instruments in a position where it is protected from
water jets and rinse water.
Once you have decided where the instrument is to be mounted in the cabin, you have to
consider the cable routing.
Special attention should be given to potential damaging factors such as e.g. hinging point for
tilting the cab.
Once you have decided where the instrument is to be mounted on the chassis, you have to
consider the cable routing. Special attention should be given to tensile forces, cuts and other
factors that may damage the cables and hoses.
Connection of compressed air
Before you carry out any installation work related to the air suspension, make sure
that the suspension has been brought to the lowest possible position.
Electrical connection
Always disconnect the battery before you perform any installation work on the
system of the vehicle.

How does it work?
The Kimax 2 on board scale is an axle pressure meter that for instance measures the pressure
on the air suspension system to indicate the load on each axle of the entire vehicle.
The Kimax 2 Radio has a 3-digit display indicating the actual weight of the vehicle or the
weight of the individual axles. LEDs warn the driver in case of overload.
A mechanical or electronic system on the vehicle maintains a fixed level of the chassis height
through a level valve which adds or subtracts compressed air to the bellows according to the
actual load on the vehicle.
The top of the bellows, shock absorber and level valve are fixed on the chassis of the vehicle.
In order to make the Kimax 2 Radio work properly on your vehicle, you need to teach the
instrument how to calculate different loads. So before you can rely on your new on-board
scale, each axle has to be calibrated after the installation. The calibration is carried out by
weighing each axle of the vehicle on a weighing bridge. While your truck is standing on the
weighing bridge you must give in the empty weight (LO) and loaded weight (HI), when the
vehicle is empty or loaded respectively.
The following diagram shows an example of calibration of an air suspended vehicle with 2
axles. When the vehicle was empty, the weight of the front axle was measured on the
weighing bridge to 4,30 tons (LO value for the front axle). Equally the rear axle was measured
to 5,70 tons (LO value for the rear axle). These LO values are now entered in the LO menu of

the Kimax 2 Radio. It is crucial to enter the values right away as the pressure in the air
suspension system will change when the vehicle is loaded. Now the vehicle needs to be loaded
in order to perform the HI calibration. When the vehicle was loaded, the weight of the front
axle was measured on the weighing bridge to 7,70 tons (HI value for the front axle). Equally
the rear axle was measured to 11,8 tons (HI value for the rear axle). In the same manner the
HI values are now entered in the HI menu of the Kimax 2 Radio. Again it is important to enter
the values right away, while the pressure in the air suspension system matches the loaded
vehicle. Now the Kimax 2 is calibrated.
The air pressure is measured on the right and left side of each axle and routed to the Kimax
instrument, to obtain the most accurate weighing results under different circumstances.

When you switch on your Kimax 2 Radio, it will show the total weight of the entire vehicle in
the 3-digit display measured in tons.
The active axle LEDs as well as the load LED are on.
When a trailer is connected to your vehicle, the active axle LEDs and load LED for the trailer is
turned on too1.
When you disconnect the trailer from your vehicle, the axle and load indications for the trailer
disappear after a few seconds, as well as the displayed weight is reduced by the weight of the
trailer.
By use of the buttons , and , you can display the individual weight of each axle, the
load you are carrying and the total weight of your vehicle.
The following pages will give a short walk through the buttons and show you the easy way of
reading and printing values from your Kimax 2 Radio. Visit www.kimax.com, and navigate to
Support and choose Training center. There you can try the Kimax 2 emulators to experience a
live test of how you can navigate between the weighing values.
Turning on the Kimax 2 Radio
When you switch on the power for your
Kimax 2 Radio, you read a 3-digit number in
the display for about 3 seconds. The number
equals the software version of your
instrument.
Next read out is an indication of the
protection of the setup and calibration of
your instrument. The writing - L- indicates
that the instrument is protected against
changing the setup and calibration, while
-U- means that your unit is unlocked and
the calibration and setup can be changed.

Now the instrument automatically starts
showing the total weight. (Including the
weight from a trailer, if a trailer is connected
and have a Kimax 2 Sensor installed).
When you press once, the Kimax 2 Radio
displays the actual weight of the first active
channel, which in this case is measuring the
input from axle #1 and only the assigned
axle LED #1 is lit up.
Press once, and the instrument will
show the actual weight of the next active
channel. The shown channel is measuring
the input from axle #2 and the assigned axle
LED #2 is lit up.
Press once again, and the instrument
will show the actual weight of the next active
channel. The shown channel is measuring
the input from axle #3 and the assigned axle
LED #3 is lit up.
Press once again, and the instrument
will show the actual weight of the next active
channel. The shown channel is measuring
the input from axle #4 and the assigned axle
LED #4 is lit up.
Press once again, and the instrument
will show the actual weight of the next active
channel. In this case the shown channel is
measuring the input from axle #5, which is
the first axle on the trailer and the assigned
axle LED #5 is lit up2.
Press once again, and the instrument
will show the actual weight of the next
active channel, which is measuring the input
from the boogie axle #6 and #7 on the
trailer. The assigned axle LED #7 and axle
LED #8 are lit up2.
Press once again and the instrument
will return to the first active channel or press
and the display will return to the
former active channel.

When you press in any of the single axle
modes, the load of the related vehicle is
shown indicated by turning on the load LED.
Press or , to toggle between the
load on your vehicle and the load on your
trailer.
When no trailer is present, pressing or
will not affect the displayed value.
Press in any of the load modes and the
total weight of the active vehicle is
displayed. This mode is displayed by turning
on both the load LED and the axle LEDs on
the active vehicle.
Press or , to toggle between the

When you press in both of the two
former total weight modes the entire load on
your vehicle + trailer is shown.
Press once again to return to the total
weight of your vehicle + trailer.
In any of the mentioned display modes above, you can turn your display off by pressing
shortly. Press shortly once more to turn your display back on.
While the display turned off, the alarm outputs A2, A3, A43, the OBC signal and the wireless4
signal is still active and broadcasted.
