be performed in an incoming inspection
within 10 days of delivery of the prod­uct. 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

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, discon­nect 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 equip­ment 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 per­formed by a trained technician in accordance with national regula­tions 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 Type­Examination 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 inspec­tion 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 perform­ing inspections, generally acknowledged rules of engineering rel­evant 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.

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 con­ductor. The position is marked by the symbol shown here, indicating the grounding con­nection.
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 mm

2

, 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 periph­eral 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.

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 sam­ple 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 electrostati­cally 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 per­manently installed parts of the weigh
cell. This causes the readout to fluctu­ate 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.

Weighing Magnetic or Magnetizable
Samples

For technical reasons, the use of mag­netizable materials in the manufacture
of weigh cells is unavoidable, primarily
because the operating principle of high­resolution weigh cells is based on
compensation of the load through
magnetic forces.

When weighing magnetic or magnetiz­able 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 quadrati­cally 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 surround­ing the weighing system. The system
can be shielded from external magnetic
fields to some extent using (soft mag­netic) plates.

10

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

RS-232 Interface Port

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 func­tions. 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, parame­ters 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

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 P key 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 P key.

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.

The type of character that can be output depends on the character‘s position:

Example:
“Calibration/Adjustment” Function via RS-232 Interface

Purpose

Adjustment is the correction of the difference between the measured value displayed and
the true weight of a sample, or the reduction of the difference to an allowable level within
maximum permissible error limits.

Features

The adjustment routine should only be started when
– The weigh cell is not loaded
– The weigh cell is tared
– The weighing signal is stable

– The sensitivity of the balance can be corrected by max. 2%.

If these criteria are not met, error message “Err 02” appears.

Error message “Err02”:
– Note ambient conditions
– Weigh cell needs stability
– If necessary, change the balance parameter settings:

Select Ambient conditions menu item 1.1.1.4 (very unstable) or execute interface

command ESC N

Adjustment can be made using different weight units:

CAL.Unit > Gram, Kilogr.

Internal Calibration

In the menu, the item Cal./adj. > cal.int. must be set.

The weigh cell housing has a built-in motorized calibration weight.

§ Select calibration/adjustment: Command ESC Z
> The internal calibration weight is loaded automatically
> The balance is adjusted/calibrated
> The internal calibration weight is removed

Internal Calibration/Adjustment

External Calibration

Configuration:
SETUP > Bal.scal. > CAL./adj. > Cal.Int.

The weigh cell housing has a built-in motorized calibration/
adjustment weight.

§ Select calibration: Command ESC Z

> The internal calibration weight is automatically loaded
> The balance is calibrated
> When the setup is configured to “Calibration and adjustment in

one,” the balance will be adjusted automatically

> The internal calibration weight is removed

Performing Calibration and Adjustment Routines

The following settings can be configured:

– Always perform calibration and adjustment in one routine

(factory setting)

– After calibration, the user has the option to quit the routine

without correction or to adjust the balance.

If no deviations are found during calibration, the calibration/
adjustment routine can be exited after the calibration is completed.
Two keys are now active:

– Start the adjustment: Command ESC f1_
– Exit the routine: Command ESC f3_

Step Execute interface Display/

1) Install the equipment in compliance with applicable laws, rules and regulations, ordinances and standards. In
particular, be sure to conform to the European Standards EN 60079-14 (Explosive atmospheres – Part 14:
Electrical installations design, selection and erection). For more information see „Verification of Intrinsic Safety“

2020665.

2) Be sure to follow the installation, operating, maintenance and servicing instructions given in the manuals
supplied.

3) The equipment shall be installed in such a way that it is protected against the entry of solid foreign objects or
water capable of impairing the safety of the apparatus. Reduce the risk of mechanical damage to a minimum.

4) The equipment must be powered by a suitable certified/approved power supply / battery pack with intrinsically
safe circuits as described in the certificate of this equipment.

5) Exposure to UV radiation is not allowed!

6) The connecting cables of the display unit and weighing cell must be permanently installed and prevented
against damage and stress caused by strain.

7) Prior to opening the equipment, disconnect the power supply or make sure that there is no potentially explosive
atmosphere or any other explosion hazard in the surrounding area!

8) The data cable connected to the equipment is considered as intrinsically safe circuit. The connection is secured
against accidental disconnection and may only be plugged in or disconnected when the power is switched
completely off. Output not used must be safeguarded by appropriate sealing cap so that the IP protection rating
is maintained. Check the correct function of the data transfer before you use the equipment in a hazardous
location.

9) If the equipment does not operate properly, unplug it immediately from line power (mains supply)!

10) All metal parts must be electrically connected to the terminal for the equipotential bonding conductor (PA). The
equipment operator is obligated to connect a lead with a gauge of at least 4 mm² (cross section) to the PA
terminal located on the side of the housing. The low resistance of this connection to the PA busbar must be
checked when the system is installed at the intended place of use. The shielding of the connecting cables may
only be used for grounding when no impermissible difference in voltage is generated and, if necessary, the
shielding is able to conduct the equipotential current.

11) Avoid generating static electricity. Use only a damp cloth to wipe down the equipment. The equipment operator
shall be responsible for preventing any risks caused by static electricity.

12) Keep chemicals and other agents, which can corrode the housing seals and cable sheaths, away from the
equipment. These agents include oil, grease, benzene, acetone and ozone. If you are not sure about the safety of
a certain substance, please contact the manufacturer.

13) Use equipment only in the temperature ranges indicated. Avoid exposing the equipment to heat.

14) The equipment operator is responsible for any non-Sartorius cables used.

15) Check the EX approval marking (particularly the group for gases/dusts and temperature class/code) on all
equipment in the hazardous area before operation to ensure that this approved equipment is permitted to be
operated in this area.

16) At reasonable intervals, have your equipment installation checked for proper functioning and safety by a trained
and certified technician.

17) If your equipment needs to be repaired, use only original spare parts supplied by the manufacturer!

18) Any tampering with the equipment by anyone, other than repair work done by authorized Sartorius service
technicians, will result in the loss of EX conformity and in the forfeiture of all claims under the manufacturer's
warranty. Only authorized specialists may open the equipment.

19) Modifications, including those to be carried out by Sartorius employees, may be permitted only after the express
written authorization has been obtained from Sartorius.

20) If an IP6x housing has been opened, close the housing with a tightening torque of 1 Nm.
