Safety
§ Once the weigh cell has been installed,
the entire product must be checked for
the following:
– Compliance with directives and
standards for electrical apparatus
– Electromagnetic compatibility of the
complete weighing instrument
– 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 describe
only 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!
! The equipment may be opened only by
trained service technicians who follow
Sartorius’ standard operating proce-
dures.
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.
! Replacement of the weigh cell and
electronics module:
Only connect devices that are made
to be operated together. Pay attention
that the serial numbers match.
! Any improper handling, modifications
or installation work will result in
forfeiture of all claims under the
warranty.
! If you use electrical equipment in
installations and under ambient condi-
tions requiring higher safety standards,
you must comply with the provisions as
specified in the applicable regulations
for installation in your country.
– Warning: RS-232 cables purchased
from other manufacturers often have
incorrect pin assignments for use with
Sartorius equipment. Therefore, be sure
to check the pin assignments before
connecting the cable, and disconnect
any lines assigned differently.
– Note on Installation:
The operator shall be responsible for
any modifications to Sartorius equip-
ment or connections of cables not
supplied by Sartorius and must check
and, if necessary, correct these
modifications.
Information on operational quality
is available on request from Sartorius
(in line with norms pertaining to
immunity).
$ If there is visible damage to the
components:
Disconnect from the supply voltage and
replace the weigh cell and electronics
module:
Do not expose the power supply to
aggressive chemical vapors or to
unnecessarily extreme temperatures,
moisture, shocks, or vibration.
$ If a service problem with the device
should occur: Contact Sartorius Service.

Intended Use
– The 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
System Description
The products are comprised of two
components:
– Compact weigh cell that can be affixed
to a smooth, even surface.
– Electronics module
– Model WZ...-NC weigh cells have
a built-in calibration weight and can
be calibrated and adjusted any time by
transmitting a control command or at
the press of a key using the optional
YAC01ED display and control unit or
the CAS-Suite software.
– These compact weigh cells can be used
to determine weights within restricted
space.
