Warning

Your Cleral onboard weighing system is a
tool. Learning to work with it can only make
it more efficient. Read this manual before
using your Sentinel PS2.

Version and Revision

Some functions described in this manual
may not be present in your PS2. This will
depend on the version and revision of your
device.

Batteries (2 X AA)

Do not invert battery position. CLERAL
recommends the following batteries:
Duracell : Power Pix ™
Energizer: Ultimate Lithium ™

Technical Support

For technical help, consult your local
authorized Cleral dealer.

Weigh bridge (certified)

Acquire the weights needed to calibrate
using a certified weigh bridge (Platform
scale). Whenever possible, record the
weights while sitting on the weigh bridge.

Pneumatic connections

Make sure that all air connections be made
according to the installation diagrams.

Lift Axles

Lift axles should always be in the UP
position while acquiring and recording the
weights in the PS2. If the vehicle is
equipped with an automatic lift axle
activation device, then you must acquire
and record the weights while the lift axle is
engaged (touching the ground) for both
empty and heavy calibration. And use the
system with lift axle down.

Fuel

To enhance the performance, fuel tanks
must be full to acquire and record the
weights.

Air Leaks

Leaks in the pneumatic system can
cause erratic and false weight readings.

Recalibration

Recalibration is necessary if you have
adjusted or replaced a leveling valve or if
you’ve replaced a mechanical sensor, air
transducer, or flexmeters.

Slopes

A slightly sloped terrain will not affect the
accuracy of your scale, but the bigger the
inclination the higher the error margin.
Learning to work with your Cleral system
will ultimately give you better precision in
these conditions.

Warranty

Cleral products are warranted against
defects in workmanship for a period of one
year from the original date of purchase.
The defective covered product will be
repaired or replaced by the manufacturer.
The defective product needs to be sent by
your local dealer to Cleral with proof of
purchase. This warranty does not cover
injury or damages caused by the use of
this product. It also does not cover all costs
connected with the replacement part
(labor, shipping and handling or other).
Cleral will not be liable for fines issued for
overweight violations while using its
products.

Contact your local Cleral dealer for repairs
and replacement parts.

Automatic sensor acquiring

Before calibrating, each activated
channel needs to be associated with a
sensor (s). To do so you need to
acquire the sensors or multiplexers
that are connected to that specific
vehicle. Each device has a unique
address.

problems section.

Important!

If a sensor is Fixed on a channel, it
does not appear in the search results
when acquiring. To see if your channel
is fixed, refer to the section Fixing a
channel.

Automatic Acquiring

Press ACQ !.
The PS2 will display «Search».

Here is an example of what the PS2
will have found. The curser points to
the first device found. Displayed is the
type of device (Air-mechanical-or
flexmeter), the «ID» and the channel
associated with the given device.

the channel is correct. Then press the
right arrow to hi-light it.

Note!

When pressing Data/Print , you will

only see the possible channels
according to your configuration (A B C

means that it is not associated to any
channel.

Important!

A configuration cannot have duplicated
channels. The PS2 will not allow you
to do so. In the example below, it is not
possible to anchor the second sensor
Air in A because channel A is already
associated to a sensor. Every other
channel is possible except channel A.

be acquired.

If you have mistakenly anchored a
channel, you can release while you
still in the menu. Replace the curser

Determining the calibration points

When the suspension has a nonlinear
effect Multi-calibration function is used.
The algorithm of this function
increases the accuracy.

Press CAL to enter the calibration

menu. Press to select Multi Cal.

With the curser on Multi Cal, press
Cycle . The first letter blinks.

Press to change the 0 (non
activated) to channel A (activated

Multi-Cal on this channel).

Press Cycle to go to the next

channel and press to change the
0 to channel B. Only the activated

channels will appear.

This feature forces you to make three
full calibration points instead of one.
Here is the method for determining the
optimal multi-curve calibration.

First, determine the average weight
that you carry on the channel to be
calibrated (Fa2 = 14000kg). Then
determine the average weight greater
than the weight that will never be
exceeded (F3 = 17000kg). Finally,
determine the weight lower than
average weight in which you do not
carry (Fa1 = 11000kg). Thereafter it is
necessary to calibrate these three
points.

Note!

You must respect the legal weight
limits at any time.

FYI

In the case of our example, the curve
Cs suspension illustrates the
deformation of the suspension by
weight. The segment Dp1 represents
the calibration curve at a single point.
As can be seen, there are differences
in weight between this line and the
curve Dp1 Cs. Cp3 curve is the curve
of multi-calibration. We note that the
differences are significantly reduced.

Following the determination of the 3­point loading, load and calibrate point

progress of loading the lightest to the
heaviest.

Press to enter the calibration

menu. Press , to bring curser to

Load Point 2 : 14000 kg

Load Point 3 : 17000 kg

With the curser on the desired
channel, use the arrows to record the
weight of point 1.

The display shows, at the bottom left
corner, the point of calibration that you
are recording.

Repeat these steps for Point 2 and 3.

Important!

If your calibration is not good, you
must repeat the entire calibration of
the three calibration points.

Important!

If you disabled the Multi-Cal, the factor
will that will be used is Point 2, it is
determined by the maximum legal
weight.
