Page 11: Description
3.1.1 Silo mounting unit The self-centering mounting unit for SIWAREX WL290 DB-S CA load cells is particularly suitable for implementation in container, platform, vehicle and roller table scales. The design was specially developed for installation in silos. The mounting unit handles the introduction of force into the load cell. -
Page 12: Structure
Description 3.2 Structure Structure The silo mounting unit consists of the following main components: ⑤ ● Base plate ⑨ ● Top plate ④ ● Two dummy blocks as installation aids Together with the load cell, the silo mounting unit represents a self-centering bearing unit. ①... -
Page 13: Application Planning
Application planning Load cell dummies Principle of operation Load cells are sensitive sensors. To protect the load cells from becoming damaged during installation and transport, install the load cells only at the last minute. Replace the load cells during installation and transport with placeholders, so-called dummies or phantoms. Dummies might be designed as follows: ●... -

Application planning 4.3 Load pick-up Figure 4-1 Proposed solution for lifting protection Load pick-up Mounting surfaces The following requirements apply to the installation areas: ● The positional and angular deviations of the mounting areas to each other correspond to the general tolerances for welded constructions in EN ISO 13920. -
Page 15: Overload Protection
Application planning 4.4 Overload protection Overload protection NOTICE Irreparable faults and damage to the load cells If load cells are used beyond the maximum working load or the maximum transverse load, this can cause irreparable faults and even fracturing of the load cell or the compact mounting unit. ●... - Page 16 Application planning 4.4 Overload protection DB-S CA 2.3 ... 113 t Operating Instructions, 10/2019, A5E46619167-AA...

Page 17: Installation
The load cell can be damaged when being handled improperly. Load cells are precision components. ● Observe the operating instructions for the load cell. SIWAREX WL200 Operating instructions (https://support.industry.siemens.com/cs/ww/en/view/109749190) ● Do not drop the load cell. ● Protect the load cells from shocks. - Page 18 Installation 5.1 Safety information/instructions NOTICE Incorrect assembly of the load cell Damaging of load cells, installation parts or load bearing implement With load cells of smaller rated loads, there is a risk of stretching the load cell bodies when attaching force transfer devices, e.g. when tightening locknuts. Torsional and bending moments, eccentric loads and transverse loads are disturbance variables.
