MNS iS motor control center System guide

MNS iS system overview

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. 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. 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

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. User friendliness Self supervision of module location, module type, power rating and automatic installation onto the communication network

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.

MNS iS system overview 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
