Length of use 60 % or 25 %

When choosing the right door opener, the load, or the length of use, is decisive in addition to the power. Here, we can provide you with solutions with 230 V or 400 V openers for average use doors or less frequented doors. 

60 % duty cycle: Normal duty cycle for 400 V openers. Designed for doors with average opening frequency. This corresponds to a maximum of 20 door cycles per hour.

25 % duty cycle: Normal duty cycle for 230 V openers. Designed for doors with low opening frequency. This corresponds to a maximum of 8 door cycles per hour. One cycle corresponds to opening and closing the door one single time.

Emergency operation of spring balanced doors (KE, E/KE)

Emergency operation facilities provide safety. They guarantee that a door can be opened and closed during a power outage.

KE (emergency hand chain): It provides standard emergency operation for openers with a standard hollow shaft of 25.4 mm. The emergency hand chain makes it possible to comfortably operate the door from the ground. 

E/KE (emergency hand chain with maintenance release system): The best and most comfortable solution: This is the standard emergency operation facility for openers with splined cog system. The emergency hand chain offers comfortable operation of the door from the ground. At the same time, the maintenance release system makes quick and inexpensive service possible, since there is no need for time-consuming disassembly of the motor or for detaching the opener from the shaft. 

Digital limit switch

An absolute value encoder guarantees precise travel cut-out. The end position of the control unit is not only conveniently set using the digital limit switch, it also keeps it correct.
