SOLENOIDS WITH OVER 50 YEARS DEDICATION TO IMPROVEMENTS
OPERATION FOR DUAL COIL SOLENOIDS:
Dual coil solenoids have two windings. One as an intermittent-service pulling winding involved in the initial phase for approximately 150 ms, with the function of moving the plunger. The second as a continuous-service holding winding, with the function of maintaining the plunger in position.
For a proper operation of the solenoid, it’s indispensable for the plunger to reach the end of and to obtain the perfect adherence to the bottom.
OPERATION FOR SINGLE COIL SOLENOIDS:
The single coil Elettrostart solenoids are for intermittent duty providing high FORCE-STROKE pick-up.
These solenoids are used to stop diesel engines when energized by actuating the fuel supply lever. The solenoid is de-energized when the engine is running, only in the stop phase it’s energized and cutting off the fuel flow. Due to its high operating power the energized time must short, while the de-energized time between two energizing phases must be long enough for the solenoid to cool down.
