1. GENERAL INFORMATION
1.1. Placement at level
Differences of a few tenths can usually be tolerated
with the 5510 bending cell series.
Nevertheless, when the differences are greater and
when the mounting is higher than three feet, it is
important, for correct use, to install shim packs that
ensure equal force distribution between them.
The references of these shim packs are:
e.g. G5510-0.6-XX
G5510-1 -XX
G5510-2 -XX
where 0.6/1/2 mm = thickness
XX =load
e.g. for a 0.5-2 t EASY-MOUNT
REF: G5510-0.6-0.5 t
1.2. Shocks
If shocks are to be expected, it is preferable to install a
shock absorber between the load and the cell. The former
is made from a stack of rubber and metal plates.
1.3. Electrical weldings
When arc welding must be done on the structure, it
is advised to install stranded ground wire in order
that the derived current does not pass through the
cell, damaging it.
It is also advised to disconnect the cells of the
measurement instrument.

1.4. Lightning
If there is a risk of lightning, it is advised to isolate the
cell the best possible and derive the former by
stranded wire. In order to do that; place a rubber sheet
under the sole and polyamide waterproof washers
under the fixing screws.

SM-I5510-CA5T (3 - 5 t)
SM-I5510-CA10T (7.5 - 10 t)
1.5. Protection hood
The load cells with strain
gauges are sensitive to
differential changes in
temperature.
Measurement errors may occur if the temperature changes fast. In which case, it can be useful to install a
protecting screen to avoid solar radiation or abrupt thermal convection (strong wind). The hood has another
function: to protect against shocks, projections (mud, water, etc.) and to avoid dirt at the level of the cell.
Screws that join the cell to the structure ensure the fixation. It is important that this hood does not hinder the
movement during the loading. If necessary, isolate the sides of the hood.
1.6. Exterior mechanical influences
In order to avoid measurement errors, the load
to be weighed should not be subject to parasitic
contributions: connecting pipes cables and stops
or draw-bolts. If there are any, they must be
installed with the greatest flexibility.
Also ladders, bridges for access should be
suitably articulated, etc (clamping).

2. ADJUSTEMENT THRUST
2.1. Setting of anti-reverse
This setting is done when the cell is UNLOADED.
Using wrenches, lock the central nuts A&B to the
middle of the threaded rod.
To turn the stop screw upwards, move nut A.
To go down, move nut B.
The setting is done when the base plate is in contact
with the head of the screw.
When the two threaded rods are adjusted, lock the D
nuts.
2.2. Setting of overload protection
This setting is done when the cell is COMPLETELY
loaded.
Unlock the central nuts A + B. Move the upper bolts E
upwards until it is against base plate F.
The setting is done when the base plate is in contact
with the seat of the nuts.
When the two nuts are adjusted, lock the G nuts.

3. CABLING
3.1. Cable
The cells are delivered with a 4-wire screened cable. The screen (shielded wire) cannot in any case be in
contact with the ground, e.g.; in metallic junction boxes, it is necessary to isolate the screen with a sheath
(thermal).
The screen can only be connected to standardized earth.
It is advised to install a thermo-retractable sheath
(retracted 4x) at the end of the cable inside a
waterproof paste in order to avoid any leak. If there is
any possible danger of damage along its wiring, it is
necessary to use an additional cable protection,
passing the cable through a pipe (steel, preferably).
3.2. Wiring
The cell wiring should be far away from power lines
(motors, transformers), and placed in separate pipes.
Soldered connections have to be applied in the
junction box, (preferably screwed connections). It is
advised to place a bag of SILICA GEL to keep dry
inside the junction box. SENSY could provide PVC
junction box with a PG9 packing-gland, which could
receive 4 or 6 parallel cells.
REF: Junction box
JBOX-4R (4 inputs - 1 output)
JBOX-6R (6 inputs - 1 output)
3.3. Parallel wiring
The cells must be installed in parallel, with the stranded mass wire joined to itself. The sense must be joined to
the cell supply, before the points of parallel wiring and the stabilising resistances.

3.4. Calibration
It must be done after the sensor has been turned on for
a while (10-15 minutes) to obtain a uniform
temperature of the installation. The cells do not usually
need to be adjusted with each other. However, when
greater precision is needed, it is sometimes necessary
to stabilise the cells individually with the resistances in
the junction box. Those resistances are of several
ohms (±10) and are installed in the supply circuit.
A parallel adjustable resistance is mounted with a fixed
resistance. The most sensitive cell will have its input
resistance increased and the least sensitive will have
its lowest input resistance. You will see that it is
preferable to work on both supply cables: schematic
mounting is given for your information and allows a
variation of 0 to 20 ohms in series on the input
impedance (2x10 Ω).
Note: A well known weight of more than 20% of the
nominal load of the system can be expected. The
calibration error is always much higher than the error
made on the evaluation of the load.
3.5. Measurement errors
When the calibration is difficult and measurement errors are observed, it is necessary
to check the installation. Mechanically, the cells must be free in the direction of the
load and well positioned. Electrically, the connections must be securing, the junction
boxes exempt from humidity and the cables intact.
If there is no fault to be seen, it is necessary to verify the internal circuit. SENSY can help to diagnose on the
basis of the associated diagnosis sheet provided in the appendix and filled in beforehand.
3.6. Insulation test
The measuring of the insulating resistance is done with
a multimeter. The standardized testing voltage is 10 V.
It is applied to a conductor. It can be determined by
disconnecting the measuring instrument and applying
voltage between one of the conductors and the metallic
mounting structure, or individually, cell by cell to situate
the leakage with precision. The insulation must not, in
any case, be lower than 2 GΩfor a 10 V voltage. This
insulation default will generate measurement errors if
the insulation resistance is lower than several hundred
MΩ. Insulation default can also be generated by
environmental conditions (temperature, humidity).

MA-5510_EN.doc Page 7 on 14 Rev: 27-03-19
3.7. Output impedance
The Wheatstone bridge is made up of 350 Ωgauges.
At the output signal (OUT+: green, OUT-: white), the
resistance is 350 Ω ± 3 Ω.
This impedance must be in accordance with the
individual cell data sheet, which can easily be
determined with a multimeter. If a wider varying
resistance is read, it means that there is a break-off or
a short circuit current; a resistance variation of several
ohms would instead be a consequence of a severe
overvoltage problem.
3.8. Input impedance
Input signal (IN+: brown, IN-: yellow): its resistance is
usually of 350 Ω ± 3 Ω. Its impedance must be in
accordance with the individual cell data sheet. If a
different resistance is read, it means that there is a
break-off or a short circuit current. It is at the input that
one finds drift compensation, slope and sensitivity
adjusted resistance.

4. USE IN POTENTIALLY EXPLOSIVE ATMOSPHERE (OPTION)
4.1. Intrinsic safety protection
Use of sensors in hazardous zones can only be done with Ex marked sensors,
delivered with one or more of the certificates hereunder:
ATEX: ISSeP07ATEX012X
SENSY’s load cells which are marked Ex i comply with the following standards:
ATEX
EN 60079-0: 2012
EN 60079-26: 2007
EN 60079-11: 2012
The use of junction boxes or additional cable lengths must be considered in the choice of protection. The
electrical characteristics of the cable being limited (see certification), it is recommended to carefully chose the
cable length and avoid any winding of the cable. After having defined all elements, it is mandatory to control if
the sensor’s output tension is still compatible with the electronic device in use and the requested accuracy.
See certificate for the special conditions for safe use.
