IMS2 IMS2 Selection Chart Digital Soft Starters The IMS2 offers a choice of soft start and soft stop profiles to ensure optimum control for all load types. The unique torque control system gives more linear acceleration than standard constant current models. IMS2 soft starters can be installed with or without a bypass contactor, and in three-wire or six-wire (inside delta) configuration. FEATURES IMS2 Starting Constant current Current ramp Torque control Kickstart Stopping Soft stop Pump stop Soft braking Protection Motor thermal model Motor thermistor input Phase imbalance Phase sequence Electronic shearpin Undercurrent Auxiliary trip input Starter heatsink overtemperature Excess start time Supply frequency Shorted SCR Power circuit Human Interface Local pushbuttons (Start, Stop, Reset, Local/Remote) Numeric display Remote input status LEDs Phase indicator LEDs Control Interface Control inputs (3 x fixed, 1 x programmable) Relay outputs (1 x fixed, 3 x programmable) Analogue output (1 x programmable) Serial output (1 x RS485) Sundry Current & Motor Temperature readout Trip Log & Start Counter Multiple function sets Function lock, Password protection Store/Restore function settings Emergency Mode operation Wall mount (models up to 253 A) Adjustable bus bar configuration Bypassing the soft starter during operation reduces heating while the motor is running, reducing the amount of ventialtion and cooling required.
