Preload Range - Sartorius CW3P Operating Instructions Manual

For CH3E models:
Platform dimensions: 300 x 400
For CH3G models:
Platform dimensions: 560 x 450
Platform dimensions: 800 x 600
Shock Resistance
The weighing platform features a rugged construction, but you should not allow objects
to fall onto the weighing pan. Also avoid bumps to the side of the unit and shocks.
The weighing platform withstands the loads specified in standard DIN 1EC68, Part 2-27.
Important Note About Planning Structures for Attachment to the Weighing Platform
The weighing platform is suitable for installation in systems. The scale drawings should
be used as the basis for selecting any necessary structures to be affixed to the platform.
Use the YAS041S fastening set to secure the weighing platform.
Moving or rotating parts on the weighing pan must be designed so that they do not
influence the weighing results. For example, rotating parts must be balanced. The
weighing pan must have clearance on all sides to prevent any falling objects or dirt from
creating a connection between the weighing platform and any permanent structures.
Cables and hoses between the weighing platform and other devices must not exert any
force on the weighing platform. These cables must not touch the weighing pan.
(For CW* models only):
When setting up systems in hazardous areas (zone 2 or 22), be sure to observe and
comply with the relevant regulations (e.g., EN60079-14).
Pay special attention that electrostatic charges resulting from moving parts
(e.g., conveyors) are avoided or discharged.
Preload Range (Zero-Point Range)
The weight of any structures that are permanently mounted on the weighing platform
constitutes the "preload." The preload is electronically compensated in the weighing
platform so that the entire weighing range is available and so that the scale can be zeroed
or calibrated (using external weights).
Larger preloads will lead to a reduction of the weighing range. The weight on the scale
may not fall below the following weighing range values:
– At least 30 kg of the weighing range must remain for models CH3G-150 1G-H
– At least 60 kg of the weighing range must remain for models CH3G-300 1G-H
!
You must always set the preload prior to verifying the scale for legal metrology.
All structures must be mounted on the weighing platform before it is connected to AC
power.
