Intended Use
Weigh cells have been developed for
– Use in measuring devices and
production machinery
– High-precision weighing within limited
space
– Precise weight determination on active
production lines
! The weigh cells are not devices; they are
modules to be added on. Only create an
EC Declaration of Conformity once the
device has been finalized. Direct sale to
end customers is not permitted due to
the lack of a CE marking.
System Description
The products are comprised of two
components:
– A compact weigh cell that must be
secured at three points
– Electronics unit
– These compact weigh cells can be used
to determine weights within restricted
space.
Safety
§ The user of the weigh cell should take
into account at least the following
points with regards to the complete
product with the installed weigh cell:
– Compliance with directives and
standards for electrical equipment
– Electromagnetic compatibility of the
complete device
– Compliance with mandatory safety
regulations.
§ Read these installation instructions
thoroughly before using your weigh
cell. That way you will prevent damage
to the equipment.
§ These installation instructions only
describe the technological specifications
of the weigh cell and the conditions
that must be observed during
installation.
! Always make sure that the equipment
is disconnected from power before
performing any work on it.
Installation
! Do not use this equipment in hazardous
areas, zones exposed to explosive
gases or dusts, nor areas exposed to
potentially explosive materials.
! Use of the weigh cell in areas where
medical equipment is operated is not
permitted.
! Do not mix up weigh cell and
electronics unit:
Only connect devices that are made to
be operated together. Make sure that
the serial numbers match.
! Any improper handling, modifications
or installation work will result in
forfeiture of all claims under the
warranty.
! The requirements pertaining to
applicable installation regulations
must be followed when using
electrical equipment in systems
and environmental conditions with
increased safety requirements.
! Installation of electronics unit:
The electronics must be installed
as set out in the guideline for
EMC compatibility.
– Warning: RS-232 cables purchased from
other manufacturers: RS-232 cables
purchased from other manufacturers
often have incorrect pin assignments
for use with Sartorius equipment.
Be sure to check the pin assignments
against the chart in this manual before
connecting the cable, and disconnect
any lines identified differently from
those specified by Sartorius.
– Note on Installation:
The operator shall be responsible for
any modifications to the equipment
and for any connections of cables or
equipment not supplied by Sartorius
and must check and, if necessary,
correct these modifications and
connections.
$ If there is visible damage to the
components: Disconnect from the
supply voltage and replace the weigh
cell and electronics unit:
$ Do not unnecessarily expose the device
to aggressive chemical vapors or to
extreme temperatures, moisture, shocks,
or vibration.
$ If you have any problems with your
device:
contact your local Sartorius office,
dealer or service center.

Installation
Storage and Shipping Conditions
– Once the equipment has been
removed from the packaging, it may
lose accuracy if subjected to strong
vibration.
– Do not expose the equipment to
unnecessarily extreme temperatures,
moisture, shocks, blows or vibration.
$ It is a good idea to save the box and
all parts of the packaging. Only the
original packaging provides the best
protection for shipment.
$ Before packing your equipment for
shipping, unplug all connected cables
to prevent unnecessary damage.
$ Do not expose the equipment to
gravitational acceleration in excess of
300 m/s2 (unless additional equipment
is installed on the load receptor).
Incoming Inspection
The customer shall inspect the
product and packaging immediately
upon delivery for proper functioning,
completeness and absence of defects.
This is to be performed in an incoming
inspection within 10 days of delivery of
the product or service. 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
repeatability test using an auxiliary
draft shield to make sure there was no
damage during transport. Sartorius PC
configuration software can be used as
a tool for this.
Equipment Supplied
– Weigh cell
– Electronics unit
– Installation instructions (this manual)
– AC adapter
– Special accessories as listed on the bill
of delivery or in accordance with any
customer-specific agreement
$ An extension cord (weigh cell –
electronics) is not included in the
equipment supplied. If required, order
separately or follow the notes on
creating an extension cord connection.
Installation Instructions
The weigh cell is delivered in antistatic
packaging along with its associated
analog electronics.
The other electronic components are
packaged separately on a base plate in
an antistatic bag.
Before operating, always make sure that
the serial numbers of the weigh cell and
the electronics match.
The corresponding cable must be
securely inserted into the electronics
before initial startup.
The device is designed to delivery reliable
weighing results when installed properly.
If you have any questions or difficulties
setting up your weighing system, please
contact the specialists at Sartorius.
When designing and setting up the
weigh cell and the electronics unit,
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 direct drafts
that come from open windows or doors.
– Avoid exposing the equipment to
excessive vibrations during weighing; for
example, caused by motors or valves.
– Protect the equipment from aggressive
chemical vapors.
– Avoid extreme moisture.
– Switch the system to Standby mode
when not in use.
– Avoid the effects of magnetism.
! Always calibrate/adjust the weigh cells
after transport.
– Equipment installed on the load
receptor can interfere with weigh cell
functions.
The user accepts all liability
for production release and the
specifications of the entire equipment.
The specifications attained by your
system may differ from those listed in
the “Specifications” chapter.
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 two hours at room temperature,
leaving it unplugged from AC power.
Connecting the Weigh Cell to the
Electronics Module
– Plug the male connector of the
connecting cable into the socket of the
electronics unit and the weigh cell
