ABB MNS iS motor control center System guide

MNS iS retains the best of MNS technology and

evolves it into the next level of operational

handling benefits for customers’ low voltage

motor control center applications.

The distinct elements in MNS is are:

Flexible control modules

Scalable for basic to complex motor starter types,

protection functions and field input/output

signal reguirements.

Integratedcontrolschematics

Allstarterlevelinterlocking scheme between

Power and control part operational safety

Physically separated and independent

operational handling of power and

control parts.

control and power module is built in.

No hardwiring orinput/output assignment

reguired.The control schematic is reduced to

assigning field l/O signal contacts only.

Standard power modules

Fully assembled, ready to use and offered for

a wide range of motor starter and energy

distribution modules.

MNS iS motor control center solution delivers

all the functions for control, protection and

monitoring ofthe motors and motor starters

using software and hardware modules for the

specific tasks.Right information is provided to

the right people at the right time.

Module and location supervision are available

as a standard.These functions ensure the

corresponding power and control modules are

installed to the correct location for the particular

motor/feeder application.

Maintenance functions are an integral part of

Hardware modules are designed to fulfill desired

tasks(power module containing electrical parts

e.g.toisolate power,control module containing

software applications etc.to control a motor)

System functions are provided as functional

modules to be downloaded to the control module

Only required functions are downloaded while

others are available as options.

they are really required.

The flexibility ofthe system allows modifications

by a simple “plug and produce” concept.

Exchanging the modules or changing the

System functionality may be enhanced at any

time without the requirement foradditional

system inherent functions and tools.

Time synchronization with a time server in the

plant orlocallyin the switchboard allows accurate

time stamps of alarms and events collected in the

control module.
