1. General
The Integrated Motor Starter-Controller (IMS-C) is an all-in-one device that provides control, protection and
monitoring functions for motor applications up to 15 kW. Thanks to its modularity, the IMS-C allows
customization of control, communication and thermal features depending on the selection of the control
unit. Control units are available in Standard, Advanced and Multi-Function.
2. Basic Requirements for the IMS-C
2.1. General Requirements
The IMS-C shall comply with the most relevant national, international standards and recommendations for
industrial electrical distribution.
The IMS-C shall have certifications according to UL and CSA standards, shall bear the CE marking, be
CCC, BV, GL, LROS, ATEX (excluding Multi-Function) and DNV certified and therefore conform to either
standards IEC/EN 60947-4-1, UL 508, CSA C22-2 N°14 or standards IEC/EN 60947-6-2, CSA C22-2 N°14,
UL 508 type E.
The IMS-C shall have a maximum rated operational voltage of 690 V.
The IMS-C shall be capable of operating at a minimum of 3600 cycles per hour with an electrical durability
of 15 million operations and a mechanical durability of 2 million operations.
The IMS-C shall be IP 40 on the front panel and IP 20 from other faces, according to 60948-1 (protection
against direct contact).
The IMS-C shall be storable in ambient air temperatures of -40°C to 85°C (-40°F to 185°F) and operable in
ambient air temperatures of -25°C to 70°C (-13°F to 158°F).
3. Requirements for Protection and Control
The IMS-C shall be able to provide control and protection functions, with additional measurement and
monitoring functions, for general motor applications below 15 kW.
3.1. Control
3.1.1. The IMS-C shall provide 2 kinds of protection and control.
For motors below 15kW, the IMS-C shall provide direct control functions through the internal contactor and
circuit breaker, without any other complementary device:
- Manual isolation, with the possibility to padlock the isolation.
- Direct control 3-phase or single-phase AC motors up to 15kW.
- Direct control 3-phase reversing motors up to 15kW.
- With a breaking capacity of 50kA/400V. For the cases requiring higher breaking capacities than
50kA, complementary devices like limiting devices will be accepted to reach 130kA, 400V.
3.1.2. Control Voltage
The control voltage mentioned in 3.1.1 shall be AC or DC controlled without any complementary device
(converter) from 24V to 240V.
3.1.3. Control Mode
The IMS-C shall provide no less than 2 control modes, which could be switched by a local input or
controlled through local control input terminals or remote control communication ports.
3.2. Measurement and Monitoring
The IMS-C shall provide motor current measurements, including 3 phase current, average current, ground
current, thermal capacity and phase imbalance current.
The IMS shall include internal current transformers, and be able to measure current without any external
complementary devices.
The IMS-C shall provide motor status monitoring, including starting counts, running hours, fault counts and
differentiation, and last 5 faults history log.

Specification for Tender
582770510
The IMS-C shall provide embedded LEDs or mechanical indication to indicate the system status, including
ready, run forward, run reversing, fault and trip.
The IMS-C, as an option, shall provide an embedded LCD HMI to display real-time monitoring values and
status. The embedded HMI may also be used to set parameters and configure the system.
The IMS-C is able to connect to an external LCD HMI which will be mounted on the front panel of the
enclosure; the external HMI may also to be used to set parameters and configure the system. The HMI
shall be able to connect one or many IMS-Cs.
The IMS-C shall be able to connect to a personal computer, and be configured and monitored through
specific software provided by the supplier.
3.3. Protection and Warning
The IMS-C shall be adaptable to different motor classes, from Class 5 to Class 30.
The IMS-C shall provide protections against risk of damage to the motor, including short circuit trip, thermal
overload trip with a selectable tripping class, under current trip, jam trip, phase imbalance trip, long start
trip, ground current trip, internal fault trip and, as an option, over current trip.
The IMS-C setting current shall be wide range to cover up to 32 amps.
The IMS-C shall also provide warnings to notify the operator, including thermal overload warning, under
current warning, jam warning, phase imbalance warning, long start warning, ground current warning and
internal fault warning.
4. Requirements for Communication
4.1. Communication Type
The IMS-C shall be able to connect to the PLC/DCS directly through its communication port using Profibus
DP, DeviceNet, Modbus, CANOpen, AS-Interface networks and Advants STB. The IMS-C shall also be able
to connect through a gateway or network interface using Profibus DP, DeviceNet, FipIO, Modbus Plus,
Interbus and EtherNet networks.
The IMS-C shall be able to change the type of fieldbus network at the last minute, by replacing a specific
communication module without changing any other main parts.
Specific plug-in ports shall be provided in the IMS-C to connect to the different fieldbus networks instead of
screw-fastened strip terminals.
4.2. Communication Features
The communication function shall enable the IMS-C control and monitoring functions. When configured to
“remote control”, the IMS-C can be fully controlled, configured and commissioned by PLC/DCS through a
fieldbus mentioned in paragraph 4.1. The IMS-C can also be monitored anytime through a fieldbus
mentioned in paragraph 4.1.
The IMS-C shall be able to connect to the distributed I/O devices.
The communication shall be guaranteed by WatchDog. WatchDog shall give fault or warning messages to
the device when there is no communication frames in the fieldbus for a threshold time. Fallback mode for
communication loss shall be accessible and selectable.
4.3. Software
No specific software is needed for the IMS-C when used without communication modules. Addressing tool
and configuration software shall be provided by the supplier when using AS-Interface communication.
Specific configuration software shall be provided for the IMS-C to connect to Profibus DP, DeviceNet,
FipIO, Modbus Plus, Interbus and EtherNet network through gateway or network interface.
5. Requirements for Implementation
5.1. Dimension
At least one dimension of IMS-C shall not exceed 45mm, so as to be installed into an iMCC drawer.

5.2. Installation
The IMS-C can be mounted not only by screw fixing, but also on 35mm DIN rail.
The IMS shall provide a rotary handle with 3 positions: Off, Ready, Trip. This handle shall be able to act as
an on-load switch and shall enable the isolator function, which means it can be padlocked in the “Off”
position.
5.3. Connection
The IMS can be wired with a standard power bus bar, if needed.
5.4. Upgrade
The IMS-C shall be modular, which means that the functionalities and communications can be upgraded by
changing some modules without using any tools.
