S System Setup
2.1 Cubicle identification
For the MNS
i
S System to operate correctly each
cubicle requires an identification number. One
M
Link
communicates to a maximum of 7
cubicles. This numbering is defined at the project
engineering stage.
Cubicle numbers are accordingly set by defined
connections of the terminal blocks to the fuse
holder on the top of the 24 V DC Control voltage
supply bar.
M
Link
identifies the cubicle based on the live
supply bars.
Figure 22 shows exemplarily the coding of
cubicle number 1.
