Warnings and Safety
Precautions

Always make sure the weigh cell
is disconnected from AC power
before performing any installa-
tion, cleaning, maintenance or repair work.
If the equipment housing is opened by
anyone other than persons authorized by
Sartorius, all claims under the manufactur-
er’s warranty are forfeited. Use only origi-
nal Sartorius spare parts.
Disconnecting equipotential
bonding conductors is not per-
mitted.
If you see any indication that
the weigh cell cannot be oper-
ated safely (for example, due to
damage), turn off the unit and lock it in a
secure place so that it cannot be used for
the time being. Observe the relevant safety
precautions and inform personnel as
required.
The casing on all connecting
cables, as well as the casing on
wires inside the equipment
housing, is made of PVC. Chemicals that
corrode these materials must be kept away
from these cables.
Make sure the weighing instru-
ment is not exposed to sub-
stances that release chlorine ions
at the place of use. If such exposure
cannot be ruled out, the operator is
responsible for establishing and observing
appropriate safety precautions, to
be checked at regular intervals for contin-
ued effectiveness.
The weigh cell may be used and
operated by qualified personnel
only. The permissible use of the
equipment is defined by the equipment
specifications and the relevant safety regu-
lations. Operating the weigh cell beyond
the specifications listed in the type-
approval certificate is not permitted, and
is considered use of the equipment for
other than its intended purpose. All restric-
tions listed in the type-examination certifi-
cate must be strictly observed.
t Once the weigh cell has been installed,
it must be checked to ensure:
−Observance of the guidelines and stand-
ards for using electrical equipment
−Electromagnetic compatibility of the
entire device
−Compliance with mandatory safety reg-
ulations.
−Installation in a Zone 1, 2, 21 or 22
hazardous area or Class 1, Division 1 or
2 hazardous location must be per-
formed by a trained technician who is
familiar with the assembly and opera-
tion of the equipment, as well as with
the procedure for putting the system
into operation. Furthermore, the trained
technician must have the required qual-
ifications and must be familiar with the
relevant guidelines and regulations.
If you need assistance, contact the
system installer, your Sartorius dealer or
the Sartorius Service Center.
Any installation work that does not
conform to the instructions in this
manual will result in forfeiture of
all claims under the manufacturer’s
warranty. Be sure to observe all restric-
tions listed in the type-examination
certificate. Operating the weigh cell
beyond the limits imposed by these
restrictions is not permitted and is con-
sidered use of the equipment for other
than its intended purpose.
Always make sure the weigh cell
is disconnected from AC power
before performing any installa-
tion, cleaning, maintenance or repair work.
The electronics module and the
optional YAC01NX display and
control unit may not be opened.

unnecessarily to extreme tem-
peratures, aggressive chemical
vapors, moisture, temperature fluctuations
or vibrations. The permissible operating
temperature range during operation is
+5°C to +40°C.
Be sure to unplug the system
from AC power before connect-
ing or disconnecting any cables.
If you are using the optional
YAC01NX display and control
unit, it must be installed a way
that limits the risk of mechanical damage.
Never open the display and
control unit.
If there is visible damage to the
components: disconnect the
equipment from AC power and
replace the weigh cell along with the elec-
tronics module.
If you use cables purchased from
another manufacturer in the
non-hazardous area/location,
check the pin assignments. Before con-
necting the cable to Sartorius equipment,
check the pin assignments in the cable
against those specified by Sartorius and
disconnect any wires that are assigned
differently. The operator shall be solely
responsible for any damage or injuries that
occur when using cables not supplied by
Sartorius. On request, Sartorius will provide
information on the minimum operating
specifications (in accordance with the
Standards for defined immunity to inter-
ference).
When using the weigh cell in
hazardous areas/locations, make
sure there is no current or volt-
age in the equipment before connecting or
disconnecting current-carrying cables to or
from the weigh cell. Disconnect the weigh
cell from AC power before connecting or
disconnecting cables.

Installation
The weigh cells are available in various
versions. If you have ordered special
options, the weigh cells are equipped
with the specified features at the factory.
Storage and Shipping Conditions
– Once the equipment has been removed
from the packaging, it may lose accu-
racy if subjected to strong vibration.
Excessively strong vibration may com-
promise the safety of the equipment.
– Do not expose the equipment unneces-
sarily to extreme temperatures, mois-
ture, shocks or vibration.
$ It is a good idea to save the box and all
parts of the packaging until you have
successfully installed your equipment.
Only the original packaging provides
the best protection for shipment.
$ Before packing your equipment, unplug
all connected cables to prevent damage.
$ Do not expose the equipment to
gravitational acceleration in excess of
0 300 m/s2 (unless additional equip-
ment is installed on the load receptor
that enables it to withstand this force).
Incoming Inspection
The customer shall inspect the product
and packaging immediately upon deliv-
ery for proper functioning, complete-
ness, and absence of defects. This is to
be performed in an incoming inspection
within 10 days of delivery of the prod-
uct. The incoming inspection must take
place before the equipment is installed.
Any obvious defects, errors, or incorrect
delivery must be reported in writing.
Defects detected at a later date must
be reported in writing immediately
upon detection.
Be sure to perform the following as part
of the incoming inspection:
– We recommend performing a repeata-
bility test using an auxiliary draft shield
to make sure the weigh cells were not
damaged in transport. You can use the
“Sartorius CAS-Suite” software or the
optional YAC01NX display and control
unit as an aid for this test.
Equipment Supplied
– Weigh cell
– Electronics module
– Installation instructions (this document)
– Special accessories as listed on the bill
of delivery, if ordered, or in accordance
with specific arrangement.
Ambient Conditions
The equipment is designed to provide
reliable results under normal ambient
conditions. If you have any questions
or difficulties when developing your
weighing system, please contact the
specialists at Sartorius. When designing
and setting up your weighing system,
please observe the following so that
you will be able to work with added
speed and accuracy:
– Avoid exposing the equipment to the
effects of extremely high temperatures;
for example, caused by other electronic
components, heaters or direct sunlight.
– Protect the equipment from drafts that
come from open windows or doors.
– Avoid exposing the equipment to exces-
sive vibrations during weighing; for
example, caused by motors or valves.
– Protect the equipment from aggressive
chemical vapors.
Switch the system to the standby mode
when not in use.
Conditioning the Equipment:
Moisture in the air can condense on the
surface of a cold weighing instrument
or other device whenever it is moved
to a substantially warmer place. If you
transfer the equipment to a warmer
area, make sure to condition it for
about 2 hours at room temperature,
leaving it unplugged from AC power.
Components Attached to the Load
Receptor
– Components that are attached to the
load receptor can adversely affect the
way the weigh cell functions. The user
is responsible for how the series is used
and the specifications achieved for the
entire system. Your specifications may
differ from those listed in the section
entitled “Specifications.”
Connecting an Optional YAC01NX Display
and Control Unit
The display and control unit can
only be connected if specified
directly at the time the order is
placed.
Protect the YAC01NX display
and control unit from mechani-
cal damage. If you discover that
the equipment has been damaged, discon-
nect it from AC power and remove it from
service.

Conditions for Installation
Before putting the equipment into operation, it is important to
make sure that the power cord on the associated power supply is
correctly connected to the power outlet (mains supply). All equip-
ment must be connected to the equipotential bonding conductor
by connecting the grounding cable (not included in delivery) to the
grounding terminals provided for this purpose on each device.
The dimensions of the grounding cable are specified in national
regulations for electrical installations. Installation must be per-
formed by a trained technician in accordance with national regula-
tions and acknowledged technological standards.
Use only cabling and extensions approved by Sartorius, as these are
made in accordance with the restrictions on permissible cable lengths
imposed by both the capacitance and inductivity values and the
requirements for electromagnetic compatibility (see the EC Type-
Examination Certificate).
Before putting the weighing system into operation for the first
time, make sure there is no hazard of explosion present at the place
of installation. If there is any indication that the equipment does
not function properly (e.g., display remains blank or is not backlit)
due to damage during transport:
– disconnect the equipment from power and
– notify your nearest Sartorius Service Center.
The weigh cell specifications for Ui, Li, Pi, Ta, temperature class,
Ci, and Li are listed in the EC type-examination certificate.
This certificate also specifies the display and control unit models
that can be used with these weigh cells.
The explosion-protected weighing system must be installed in
accordance with acknowledged rules of engineering. These include
national and international laws and regulations (such as VbF,
EX-RL, DIN EN 60079-14, DIN VDE 0166, DIN VDE 0100, DIN VDE
0101, and DIN VDE 0800).
In particular, the conditions described under Item 17 of the KEMA
EC type-examination certificate, “Special Conditions for Safe Use,”
must be observed. Furthermore, national regulations for accident
prevention and environmental protection must be observed at all
times.
Before you operate your weigh cell in a hazardous area/location,
it must be inspected either by a certified electrician or under the
guidance and supervision of a certified electrician to make sure that
the weigh cell complies with the applicable regulations. Determine
whether your weigh cell must be reported to the technical inspec-
tion authorities (such as the trade board) in your country. The system
must also be inspected during operation. The system should be
inspected at intervals which allow for early detection of the faults
that occur as a result of normal wear and tear, so that they can
be corrected before damage is caused. In any case, inspection must
be performed at least every 3 years. Other conditions and standards
that regulate the installation and operation of the equipment and
are applicable in your country must be met as well. When perform-
ing inspections, generally acknowledged rules of engineering rel-
evant to these conditions must also be applied. If the unit housing
is opened by anyone other than persons authorized by Sartorius,
or if the equipment is installed or operated incorrectly, this will
result in forfeiture of the approval for use in the stated hazardous
area(s)/location(s) and of all claims under the manufacturer’s
warranty.
YPSC01-Z ..

t Connecting an Equipotential Bonding Conductor (Grounding)
−If the weigh cell is in a hazardous area/location, it must be grounded (i.e., an equipoten-
tial bonding conductor must be connected). This connection should be made by
a trained technician. The weigh cell is equipped with a connector for the grounding con-
ductor. The position is marked by the symbol shown here, indicating the grounding con-
nection.
Use a stainless steel screw (M6 thread) to connect the grounding conductor.
We recommend using a tooth lock washer to prevent the screw from coming loose.
The wire used for the grounding conductor should have a cross-sectional diameter of at
least 4 mm2, with a suitable ring lug attached.
The grounding cable must be installed in such a way that it is not under mechanical
stress and so the screw will not become loose. Connect all equipment, including periph-
eral devices, to the equipotential bonding conductor.
Connecting the Weigh Cell to AC Power
t Before putting the weigh cell into operation, make sure that the power cable is
correctly connected to the electrical outlet; it is especially important to make sure
the grounding cable is attached to the housing of the power supply. All devices used
must be connected to the equipotential bonding conductor via the retainers provided on
each device. Installation must be carried out by a certified electrician according to the
valid standards of technology.
Before putting the equipment into operation for the first time, make sure that the
area of installation is not hazardous. If the equipment shows any signs of mal-
function as a result of damage during shipment (display remains blank, display
not backlit even with a weight readout, weight value not repeatable, readout does not
stabilize, etc.), disconnect the equipment from AC power and contact a Sartorius service
technician.
t YPSC01-X: flameproof power supply:
−Lay both cables in a manner that is secure and protected.
−Flexible installation of cables with threaded fasteners can be carried out on request.
t Check the voltage rating and the plug design.
−If they do not match the rating or standard you use, contact your Sartorius office or dealer.
−Use only original Sartorius power supplies:
−YPC01-Z... (for use outside hazardous areas/locations)
−YPC01-X (for use within hazardous areas/locations)
To operate the weigh cell in a hazardous area or location, please comply with the
following:
– Currently valid standards and regulations for installation of explosion-protected
equipment in such areas
–
Installations in Zone 1 must be carried out and checked by a certified electrician.
t Plug the female connector of the blue intrinsically safe power supply cable into the
socket on the weigh cell. Secure this connection by tightening the knurled collar.
Be sure to connect the power supply to the electronics module before plugging
the equipment in to AC power.
Install the power cable so that it is protected from damage.
The intrinsically safe connector for the power cable (primary side) is not part of
the standard equipment supplied (open cable ends).
Connecting Electronic Peripheral Devices
Make absolutely sure to unplug the weigh cell from AC power before you connect
or disconnect a peripheral device (display and control unit or PC) to or from the
interface port.
7

Warmup Time
The amount of warmup time required depends in part on the system in which the
weigh cell is installed. To deliver exact results, the weigh cell must warm up for at
least 30 minutes after it is connected to power for the first time. Only after this
time will the device have reached the required operating temperature.
Leveling the Load Receptor and User-Specific Transducer
t Remove the (S1) screw.
t Use the (S2) screws to radially position and level the load receptor (minor height adjust-
ment also possible).
t Attach the (S1) screw to affix the load receptor and tighten it as indicated in the table
below listing the torque values.
t Attach any user-specific transducer to the threaded fastener (S3) on the load receptor and
tighten it as indicated in the table below: Maximum load on load receptor.
t The user-specific transducer must be rigid and securely connected to the load receptor.
Maximum load on load receptor:
Model Meck S1 S2 S3
WZA623-NX 2.5 Nm 1 Nm 1 Nm 2 Nm
WZA6202-NX 6 Nm 4 Nm 2 Nm 4 Nm
If the load is not centered on the load receptor, the corner load moment Meck may not be
exceeded, since this could lead to a defect in the weigh cell.
The force “G” is comprised of the weight of the sample and the non-centric load on the
weigh cell.
The load receptors should be constructed so that they are stiff and cannot be bent or
twisted.
Example: What is the maximum permissible length of the cantilever
(on WZA623-NX in this instance)?
It is assumed that the load is connected to a cantilever that has a uniform width.
The cantilever utilizes the necessary preload of 600 grams on the WZA623-NX.
Meck Arm ~ 1 R + GArm GArm = 9.81 m/s2 + 0.6 kg
= 5.9 N
Meck Last = R + GLast GLast = 9.81 m/s2 + 0.62 kg

The maximum length that the cantilever
can be without destroying the system is
200mm. As a result of handling, other
moments can occur, which must be taken
into consideration. In general, we recom-
mended testing first because there can
be undesired repercussions. Drafts can
influence results as well.

Leveling the Weigh Cell in a Portable Weighing System (Leveling Feet Optional)
Purpose:
– To compensate for uneven areas at the place of installation
– To ensure that the weigh cell is placed in a perfectly horizontal position for consistently
reproducible weighing results
– Always level the weigh cell again any time after it has been moved to a different location.
§ Adjust the leveling feet until the air bubble is centered within the circle on the level
indicator.
Permanently Installed Weigh Cells
– Adjust the weigh cell after it has been installed in the system in its permanent location
(see next page).
The weigh cell must be leveled again any time the location or position of the weighing
system is changed.
– For optimum operation, install the weigh cell in a horizontal position.

Operation
Notes on Analytical
Weighing with Weigh Cells
Handling of Samples and Containers
Samples should be acclimatized to the
temperature of the weigh cell to avoid
negative effects on results, such as
measurement errors and fluctuations
caused by air buoyancy resulting from
convection currents across the surface
of the sample.
These negative effects increase as the
volume and/or surface area of the sam-
ple increases. For this reason, the size of
the container should be appropriate for
the sample.
Samples and containers should not be
touched by the operator’s hands, as the
hygroscopic effect of fingerprints and
the effect of the hand’s temperature
can influence the measurement results.
Samples must be applied very carefully,
whether manually (using forceps) or
automatically (by a robot or filling
system).
When designing a draft shield device,
steps must be taken to keep the
increase in temperature within the
weighing chamber to a minimum
(e.g., using a bypass).
Weighing Electrostatically Charged
Samples or Containers
If a sample or container is electrostati-
cally charged, significant errors may
result during weighing. Materials with
low conductivity, such as glass, plastic
or filters, are particularly susceptible to
static electricity (resulting, e.g., from
friction) because the weighing pan can
discharge the static electricity only very
slowly.
The result is a force action between
the charge on the sample and the per-
manently installed parts of the weigh
cell. This causes the readout to fluctu-
ate constantly.
Ionization can be applied to make the
air around the sample conductive. This
allows the charge to be compensated
through the air, or discharged through
the ground (grounded).
The area around the weigh cell can
also contain charges that negatively
affect the accuracy of weighing results.
Appropriate steps taken in the design
of a draft shield device can counteract
such effects. In the process, be sure to
install devices that are suitable for use
in the particular hazardous zones.
10
Weighing Magnetic or Magnetizable
Samples
For technical reasons, the use of mag-
netizable materials in the manufacture
of weigh cells is unavoidable, primarily
because the operating principle of high-
resolution weigh cells is based on
compensation of the load through
magnetic forces.
When weighing magnetic or magnetiz-
able samples or containers, interaction
between the sample or container and
certain parts inside the weigh cell may
have a distorting effect on the weighing
results.
To keep such effects to a minimum,
we recommend increasing the distance
between the sample/container and the
weighing system using a non-magnetic
material. The force is reduced quadrati-
cally with the increase in distance.
Magnetizable or magnetized samples
and the weigh cell itself interact with
magnetic fields and magnetizable or
magnetized parts in the area surround-
ing the weighing system. The system
can be shielded from external magnetic
fields to some extent using (soft mag-
netic) plates.
Calibration/Adjustment
Calibration/adjustment can be per-
formed as follows:
– Using control commands sent by the
CAS-Suite configuration software from
Sartorius, installed on a computer
(see page 18 for the commands)
or
−Using the optional YAC01NX display
and control unit

Below-Cell Weighing
A port for a below-cell weighing hanger is located on the bottom of the weigh cell.
t Remove the cover plate.
−Threaded fastener for hook: M3
Overload protection
−Standard feature on the WZA623-NX model
Models WZA6202-NX:

# = Factory setting for “PC-USB” interface

Purpose
The weigh cells are equipped with
a data interface for connection to
a computer or other peripheral device.
Computer
You can connect a computer to alter,
start or monitor weigh cell functions.
Features
Type of interface: Serial interface
Operating mode: Full duplex
Standard: RS-232
Transmission rates: 600 to 115,200 baud
Parity: Space, odd, even
Character format: Start bit, 7-bit ASCII, parity 1 or 2 stop bits
Handshake mode: For 2-wire interface: software (XON/XOFF)
For 4-wire interface: hardware (CTS/DTR)
Operating mode: SBI (ASCII), XBPI*
* XBPI operating mode:
Always with 9600 baud, 8-bit, parity odd, 1 stop bit.
There are numerous additional commands for communicating with the weigh cell.
Please contact Sartorius for more information about their operation.
Protocols
For data exchange, the interfaces are configured with the following protocols:
– Printer output
– SBI (Sartorius Balance Interface): Sartorius standard protocol for output to a PC or control
unit. This simple ASCII-based protocol allows you to use ESC commands from your PC to
control the basic weighing functions.
– xBPI (eXtended Balance Processor Interface, also known as X-Bus): Binary protocol with
extended scope of commands. This protocol lets you control numerous weighing func-
tions. For further information on this, please contact Sartorius. To use the protocols,
application software must be installed on the PC.
Synchronization
During data communication between balance and PC, messages consisting of ASCII or
binary characters are transmitted via the interface. For error-free data exchange, parame-
ters for baud rate, parity, handshake mode, and character format must be identical for
both units. You can configure the respective settings in System Settings (menu).
In addition to these settings, data output for the balance can also be made dependent on
several conditions that are defined in the individual tasks. These conditions are described
under each of the tasks.
17
RS-232 Interface Port

Data Output
You can define the data output parameter so that output is activated either when a print
command is received or automatically synchronized with the display or at defined intervals
(see application programs and autoprint settings).
Data Output following Print Command The print command can be transmitted by pressing the Pkey or by a software command (EscP).
Automatic Data Output In Autoprint mode, data is output to the data interface port without an extra print
command. You can have synchronized data output automatically at defined display update
intervals, with or without the stability parameter. The interval time depends on the balance
operating status and balance type.
If the automatic data output is activated in the Device Configuration, it starts immediately
after the balance is turned on. You can also configure whether the automatic data output
can be stopped and started with the Pkey.
Data Output Formats
You can output the values displayed in the line for measured values and weight units with or
without an ID code. Configure this output parameter in the Device Parameters menu (Menu
> Device parameters > Configure data output > Line format).
Example: Output without Identification + 253 pcs 16 characters are printed
Example: Output with Identification Qnt + 253 pcs 22 characters are printed

Data Output Format with 16 Characters
Display segments that are not activated are output as spaces.
