ERN - THE POWERFUL
Due to a diameter of 45 mm and 59 mm, the motor is suitable for 60's and 70's 8-square shafts. The motors in the ERN/ERFN series can be operated through an emergency crank (optional accessory) in the case of power failure. The ERFN1070-120 is equipped with a radio receiver as well as a hindrance detection function. All the motors in this series are maintenance-free with a high life span and are equipped with a thermal overload protection system. The hindrance detection function of the ERFN 1070-120 becomes active when an obstacle is recognized during the upwards movement. This in turn prevents damage to the roller shutters and the motor.
