MNS iS system overview

Function module concept

MNS iS motor control center solution delivers

all the functions for control, protection and

monitoring of the 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.

Hardware modules are designed to fulfill desired

tasks (power module containing electrical parts

e.g. to isolate 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.

System functionality may be enhanced at any

time without the requirement for additional

hardware or wiring.

Time synchronization with a time server in the

plant or locally in the switchboard allows accurate

time stamps of alarms and events collected in the

control module.

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

the system. Asset monitors measuring system

performance data (e.g. outgoing line

temperature, number of insertions) allow

scheduling of maintenance activities only if

they are really required.

The flexibility of the system allows modifications

by a simple “plug and produce” concept.

Exchanging the modules or changing the

parameter settings is easily achieved by using

system inherent functions and tools.

Components overview

The power module MStart/MFeed comprises:

• The electrical isolator.

• The short circuit protection device (fuses or

circuit breaker).

• Contactor and any electrical control equipment

and status indication.

• The sensor module (measuring the electrical

values, which are then available to the process

via the MControl module).

The integrated motor controller module MControl

(located in the control compartment) comprises:

• The processor performing all the protection,

control functions and monitoring functions. It

exchanges information with the MStart/MFeed

via an internal bus.

• I/O interface modules providing an interface to

external components for control, protection

and indication.

The interface module MLink serves as the

gateway to higher level systems which

communicate via the internal bus to

all MControl modules.

A local human system interface MView is available

to monitor the MNS iS status and display

information on each connected motor/feeder.
