smooth starts reduce your costs
Adjusting the motor torque is best done by controlling the current in all three phases. 3-phase control offers symmetrical and balanced currents without the drawbacks of additional energy losses, noise and vibration normally connected with 2-phase soft starters.
Emotron TSA Soft Starts incorporate 3-phase control together with sophisticated algorithms for torque control. Conventional Soft Starts use a pre-defined voltage ramp to control the start. With Emotron TSA, the actual motor torque is continuously calculated and controlled according to the application requirements. This torque control ensures an ultra-smooth start with constant acceleration. The torque control means the starting current is reduced even further by up to 20%. You can use smaller fuses and less expensive cables, and will thus benefit from lower installation and energy costs. The smooth starts also lead to less mechanical stress, improved process control and reduced maintenance costs.

features & Functionality
A number of key features set the TSA apart from other Soft Starts.
protect your process and maximize efficiency
A built-in load monitor protects your machine and process against costly downtime, equipment damage and break-down. It reacts immediately if a crusher is jammed, a pump is running dry, a compressor is idling, or a fan is operating inefficiently due to a blocked filter. This is achieved by continuously calculating the motor torque used. Any deviation from your selected load levels will result in a warning or a quick but smooth stop.
The actual load can be remotely displayed via analogue or fieldbus communication output. The monitor can also be used to determine when a process is ready, for example, when the cored viscosity level is reached in a mixing process. You can rely on an efficient and reliable operation protected from damage and interruptions.
direction of a fan can be controlled by programming two inputs for start left/right. No external PLC is required. You can connect an external alarm signal to stop the motor if a problem occurs. An analogue sensor can be connected directly to the Emotron MSF to control the start and stop levels of a pump.
Slow speed and jog operations
Apart from ramping up and down the speed between zero and rated motor speed, Emotron TSA Soft Starts offer low speed operation in both forward and reverse direction without additional hardware. Slow speed or jogging forward or backward can be useful for aligning a load or having the motor running at low speeds for test or service purposes. Examples of applications where such low speed or jog operation is valuable are loading/unloading of centrifuges or mixers or positioning of feeding conveyors.
Emotron TSA Soft Starts are among the smallest in their class. Due to the space-efficient construction and somewhat unique bypass design, a compact and user-friendly footprint has been achieved.
smart stops - smooth or quick
Emotron TSA offers efficient solutions, whether the need is a smooth or a quick stop. A linear stop of a pump eliminates the risk of water hammer. No motor-controlled valves are needed. Built-in braking functionality ensures quick and safe stops of mills and saws without mechanical brakes.
Multi-lingual control panel with single-function keys and copy function
Designed for global application the Emotron TSA soft starters carry a multi-lingual display unit as standard. The control panel has an easy-to-use menu system and dedicated menu and start/stop keys.
real time clock and programming blocks
The Emotron TSA Soft Start offers built-in programming blocks, such as logical functions, comparators, SR Flip-Flops, counters and timers. This opens the way for customizing functionality according to your requirements. A Real Time Clock provides information about the actual date and time of the day. The real time information is used for time registration in the event log and to enable pre-programmed starting and stopping at certain date and time.
Easy installation and easy to use
Installation is quick and cost-efficient, since no additional equipment is required. Everything you normally need is included in an Emotron TSA unit. A number of options let you customize the Soft Start functionality.
Protect your motor
All Emotron TSA Soft Starts have - as standard - a motor PTC thermistor input for thermal protection of the motor. The isolated thermistor inputs conform to DIN 44081/44082. In addition, the Soft Start allows for connection of up to 6 PT100 temp sensors. TSA software also includes an easy to use I2t motor thermal protection function.
