5.1 Safety instructions
NOTICE
Welding or lightning strike current flowing through the cell can damage it.
All electrical welding on the weighing system must be finished before mounting the load
cells.
When installing the load cell, immediately bypass the load cell with the flexible
copper strap provided for this purpose (included in the equipment supplied, see
Chapter 4.1 ).
During any additional electrical welding work near the load cell:
- Disconnect the load cell cables.
- Bypass the load cell using the flexible copper strap.
- Make sure that the grounding clamp of the welding set is fitted as closely as possible
to the welding joint.
The following must be observed during installation:
- Do not lift or transport the load cell by pulling on the cable.
- Avoid shock stress (falling down, hard shocks).
- The load cell must be installed so that its axis is vertical.
- Load forces must act in the measuring direction of the load cell.
- The load cell must be suspended as follows during installation:
NOTICE
Changes of temperature >15 K/h may influence the measuring accuracy.
Make sure to protect the load cells from direct heating or cooling effects (sun, wind,
heat radiation, fan heaters), e.g., heat protection screens or heat protection
housings are to be installed if necessary.
NOTICE
Force shunts may cause measuring errors.
All incoming and outgoing lines (hoses, pipes, cables) must be coupled to the
measured object as flexibly as possible.
