ABB-MNS iS motor control centerSystem guide

MNS iS system overview MNS iS – Innovative design 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.
