NOTICE
Damage to load cells through incorrect mounting
• Provide indented claws or crane eyebolts on the load bearer to ensure that hoisting gear can
be used safely.
• Load cells must never be overloaded. Put the load carrier down slowly for this reason.
With load cells of smaller rated loads in particular, there is a risk of stretching the load cell
bodies when attaching force transfer devices, e.g. when tightening locknuts.
• Adjust the existing overload protection to ensure that it can still reliably sense transfer of the
required load. The overload protection must permit a rise in weight unhindered until the
setpoint weight is reached.
• Protect the gap between the load cell and overload protection from the build up of dirt or
ice.
• The load must be introduced in the measuring direction of the load cell. Torsional and
bending moments, eccentric loads and lateral forces are disturbances. These disturbances
falsify the measured result and can damage the load cell if the permissible limits of the load
cell and mounting components are exceeded.
The mounting components normally allow so much room for movement that heat
expansion will not result in lateral loading.
• Protect the load cell against higher impact energy levels by using Siemens mounting
accessories.
NOTICE
Destruction of load cells
Proceed carefully with installation. The load cells can be destroyed if they are installed
incorrectly.
4.2 Procedure for mounting the device
Procedure for mounting the device
1. Observe the installation guidelines for the mounting components.
– You can nd dimension drawings of installation elements under Dimension drawings
(Page 73).
– Lay the cables for the load cells through cable glands in the form of a vertical downwards
loop to discourage the penetration of water.
2. Check that the load cells and mounting components are installed correctly, e.g. by checking
the mounting dimensions and oscillation distances.
