4.4. Weighing Modules for the Operation of Standard Load Cells
The weighing system controller can accommodate up to two weighing modules. Depending on the application –
legal for trade scale or industrial application – it can be selected among various weighing modules.

Tab. 4.3: Technical characteristics of weighing modules
Hint: If two weighing modules of the same type are used, then the sensor address of the second module is
increased by one (see RS485-ID in parentheses).
4.5. Weighing Module Upgrade
You can upgrade the weighing system controller with a second weighing module. Auch eine Umrüstung der
Wägemodule ist möglich.
ATTENTION: LEGAL FOR TRADE APPLICATIONS
If any of the relevant weighing components will be changed, the operating license als legal for trade scale
expires. Please read chapter 9 to this.
IMPORTANT:
For all service operations use an appropriate protection against electrostatic
discharge. Follow the safety instructions within the operation manual of your
instrument.
Step 1: Shut down your operating system. Disconnect the weighing terminal from the power
source. Open the enclosure of the weighing terminal.
Step 2: Remove the interlock of the PCI plug-in card. Afterwards you can take out the
weighing system controller.
Step 3:
(only for retrofit) Remove the wire strap from the weighing module to replace and remove the two M3
x 6 mm cross slot screws. Pull out the weighing module.
Step 4: Insert the new weighing module into the corresponding socket. Secure the weighing
module by fastening the supplied M3 x 6mm cross slot screws.
