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.

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.

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.

Measurement variables

Selectable temperature, current and voltage

measurement for various protection needs

for both motor and the switchgear itself.

No traditional transformers are utilized

for any measurements.

Information distribution as required

Industry standard communication interfaces,

such as Profibus DP, ProfiNet, Modbus RTU,

Modbus TCP and OPC are available, enabling site

wide distribution of information (operator,

maintenance, management).

System accessibility with ‘off the shelf’

web browser based devices

With an inbuilt web server functionality, the user

can select any web browser based device to

interrogate the system.

Standard power modules

Fully assembled, ready to use and offered for

a wide range of motor starter and energy

distribution modules.

Flexible control modules

Scalable for basic to complex motor starter types,

protection functions and field input/output

signal requirements.

Integrated control schematics

All starter level interlocking scheme between

control and power module is built in.

No hardwiring or input/output assignment

required. The control schematic is reduced to

assigning field I/O signal contacts only.

User friendliness

Self supervision of module location, module type,

power rating and automatic installation onto the

communication network.

User friendliness

MNS iS provides integrated user tasks, like

module supervision, lifecycle management,

contact temperature supervision and

power loss supervision.

Less engineering complexity

MNS iS is the easiest way to plan, engineer and

manage a low voltage switchgear system.

Project implementation

MNS iS helps you to reduce your project costs by

offering a shorter project duration due to high

standardization and reduced engineering.

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:

Power and control part operational safety

Physically separated and independent

operational handling of power and

control parts.

MNS iS system overview

MNS iS – Value inside

High protection and safety

MNS iS and its clear segregation of power and

control compartments offers highest personal,

system and supervision safety possibilities.

Standardization

Maximum simplicity due to standardized power

modules – fully assembled and ready to use for

a wide range of motor starter and energy

distribution modules.

Lower lifecycle costs

These are defined in three ways; less downtime,

less fault finding and less inventory.

Information variety

MNS iS offers latest HMI technology, remote

management, innovative plug and produce

technology and real time plant condition

monitoring.

Complete solution

ABB offers the possibility to provide an all in

one solution when MNS iS is used in conjunction

with other power and automation technologies

from ABB.

Pro-active maintenance

MNS iS with Condition Monitoring indicates

conditions before a failure occurs, enabling

pro-active maintenance possibilities.

Application

The manual motor starters protect the load and the installation against short-circuit and overload. They are three pole protection

devices with thermal tripping elements for overload protection and electromagnetic tripping elements for short-circuit protection.

Furthermore, they provide a disconnect function for safely isolation of the installation and the supply and can be used for the

manual switching of loads.

The manual motor starters have a setting scale in amperes, which allows for direct adjustment of the device without any additional

calculation. In compliance with international and national standards, the setting current is the rated current of the motor and not the

tripping current (i.e., no tripping at 1.2 x I; I = setting current).

Manual motor starters are electromechanical devices for motor and circuit

protection. These devices offer local

motor disconnect means, manual ON/

OFF control, and protection against

short circuit, overload, and phase loss

conditions. Manual motor protection

saves cost, panel space, and ensures

fast and reliable short-circuit protection

by reacting within milliseconds. Closecoupling adaptors are available for

combination with ABB contactors.

Manual motor starters (also known

as motor protection circuit

breakers or manual motor

protectors) are electromechanical

protection devices for the main

circuit mainly used to switch

motors manually ON/OFF and

protect them fuseless against

short‑circuits, overloads and phase

failures. Fuseless protection with a

manual motor starter saves costs,

space and ensures a quick reaction

under short-circuit condition, by

switching off the motor within

milliseconds. Fuseless starter

combinations are setup together 

with contactors.

Plant description

Pipelines are the most efficient way to distribute gas and

cover big distances especially in location with critical

environmental conditions like deserts, glaciers, high

mountains. To keep pressure and temperature of gas at the

right level, Gas Compressor Stations are present and placed

at 10 to 150 Km intervals along the pipeline. The low voltage

MCC is one of the most important and critical component of

those compressor stations

The two WAGP Gas Compressor Stations in Utorogu and

Oben are based on the latest ABB MNS iS technology

installed into prefabricated E-houses.

The ABB MNS iS is the right solution to comply with the high

level of integration and compactness requested for the WAGP

Utorogu and Oben Gas Compressor Stations.

The ABB MNS iS Power and Motor Control Centers for the

WAGP project are fully integrated with the station DCS via

serial link (Profibus DP protocol) and are built in compliance

with Shell DEP standards.
