Fig. 4.2: PW20i mounting instructions
The PW20i load cell must be mounted on a clean surface with a flatness of 0.1
mm. An overload protection in the tensile and compressive directions protects
the load cell from overload.
It is recommended that the load unit is positioned in the centre of the platform
to minimise corner load errors and torques.
The following must be noted when installing several PW20i in a system with an
RS-485 bus system:
The printed production number (rating plate) is required for setting up the data
communication. If the rating plate can no longer be seen after installation, the
numbers of all PW20i should be noted beforehand. This enables address
assignment during the initial start-up.
Alternatively, each PW20i can be connected individually to a PC to assign
different addresses before connection to the RS-485 line.
