Connection of an MLC / MBS / MUS / MCS / MSI / MMI belt scale to WP241
The following graphic clarifies the interfacing of all Siemens belt scale types to SIWAREX
WP241. When using several MSI scales (MMI2 or MMI3) installed in sequence, all additional
load cells are connected in parallel in the junction box as shown in the graphic.
All load cells must always be connected in parallel in the junction box. With 4-wire load cells,
you must additionally set a jumper between EXC- and SEN- and between EXC+ and SEN+
in the junction box. With 6-wire load cells, the jumpers are omitted and all conductors of the
same type are connected in parallel in the junction box and directly through to the
SIWAREX.
