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. 
–  Do not expose the equipment to unnec-
essarily extreme temperatures, moisture, 
shocks, blows 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 
unnecessary damage. 
$ Gravitational acceleration 0 300 m/s

Do not expose the equipment to  
gravitational acceleration in excess of  
0 300 m/s

 (unless additional equip-
ment 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 repeat-
ability test using an auxiliary draft 
shield to make sure the weigh cells were 
not damaged in transport. You can use 
the YAC01ED display and control unit 
or the CAS-Suite software as an aid for 
this test. 
  Equipment Supplied

of delivery or in accordance with any 
customer-specific agreement
  Installation Instructions
  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 direct 
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.
–  Avoid extreme moisture.
  Switch the system to the standby mode 
when not in use.
–  Avoid the effects of magnetism.
! Always calibrate/adjust the weigh cells 
after transport:
–  WZA...-N, WZA224ND:  
External calibration
–  WZA...-NC: Internal calibration
–  Equipment installed on the load 
receptor can interfere with weigh cell 
functions. The user accepts all liability 
for production release and the speci-
fications 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 2 hours at room temperature, 
leaving it unplugged from AC power. 
  Connecting the Weigh Cell to the 
Electronics Module
–  Plug the connecting cable into the 
socket on the electronics module and 
the male connector on the weigh cell
  Connecting an Optional Display and 
Control Unit
–  The YAC01ED display and control unit 
can be installed while operations are 
running (hot plug-in).
§ Plug the cable into the socket on the 
electronics module.
