Santerno Soft Starters
 
The soft starter sets new standards for motor control. The adaptive acceleration control determines the properties of motor and load within few starts. Subsequent starts and stops are performed according to the selected characteristic (early, constant, late acceleration, deceleration). The function provides ideal control of drives with high inertia or different pump head heights.
Soft Starters has a Maximum reliability and protective functions prevents improper operation conditions and warn or trip in case of over-current, under-current, excess start time, over-temperature, phase loss, phase imbalance and many others. A reset can be performed automatically after an adjustable waiting time. The emergency function ignores trip causes. The sophisticated thermal motor model makes it possible to react to increased load even before the motor is over-heated. Nine types of parameter presets cover the requirements of most standard applications and the 99 past events gives the maximum reliability.
The total control over the starting current and starting torque, frequent start capability without performance variations, optimum start performance for every start even in applications where the load varies between starts, soft stop control for applications such as pumps and conveyors, braking for reducing deceleration times.

The main advantages of the soft starter are the motor and load protections such as programmable electronic motor overload for advanced motor protection, phase imbalance and phase loss protection, phase rotation protection to prevent reverse rotation of motor and load, stall protection to prevent damage from jammed loads, undercurrent protection to detect abnormal load conditions, thermistor input for direct connection of motor thermistors, restart delay, shorted SCR detection and automatic power circuit verification.
