5.1 Safety instructions
NOTICE
Welding or lightning strike current lowing through the cell can damage it.
All electrical welding on the weighing system must be inished before mounting the load
cells.
When installing the load cell, immediately bypass the load cell with the lexible
copper strap provided for this purpose (included in the equipment supplied, see
Chapter
During any additional electrical welding work near the load cell:
-
Disconnect the load cell cables.
-
Bypass the load cell using the lexible copper strap.
-
Make sure that the grounding clamp of the welding set is itted 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 vertically and centrally in the mounting kit.
-
Load forces must act in the measuring direction of the load cell.
-
The load disc must not be subjected to transverse forces.
-
The membrane on the underside of the load cell is thin and, consequently, sensitive.
The surface in the mounting plate supporting the load cell must be clean, i.e., free of
grains of sand, material residues, etc.
NOTICE
Changes of temperature >15 K/h may inluence the measuring accuracy.
Make sure to protect the load cells from direct heating or cooling efects (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 lexibly as possible.
