UW-MTX 3.5/4.5 releases are backed up by different supplementary modules to enhance the functionality of the
Protection & Control Unit to provide customer more advance and complete system protection.
Matrix Modules can be looped with
another module using RJ45 modular
connectors ensuring reliable and error-
free communication, supporting
unique CAN bus protocol.

Self Diagnostic Test:
All the modules (Except PS Module) are having self diagnostics test button provided on the front facia. Self test of the
supplementary module can be performed by removing the CAN communication connection of the P & C unit with
the PS module and 24V DC supply connected (
After test RED led indicates module is not healthy and GREEN indicates module is healthy.
which is looped with the supplementary modules).
