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.
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...
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.
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. ●...

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.

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.
Installation 5.2 Dismantling NOTICE Improper installation of the load cell in the compact mounting unit An improper installation of the load cell in the compact mounting unit can destroy the load cell and the compact mounting unit. ● Check that the load cell and compact mounting unit are installed correctly, for example, by checking the mounting dimensions and oscillation distances.

Service and maintenance Servicing and maintenance Important notes on cleaning NOTICE Damage to load cells, measurement errors Dirt must not be allowed to accumulate in the vicinity of a load cell. Do not subject cable glands, sealing elements and flat seals directly to the jet from a high- pressure hose.
Service and maintenance 6.2 Disposal Disposal Note Special disposal required The device includes components that require special disposal. ● Dispose of the device properly and environmentally through a local waste disposal contractor.
