JB 520C23 - Shutter Blind Actuator, 1 x AC 120 V, 6 A

Shutter Blind Actuator, 1 x AC 120 V, 6 A

• For drives with electromechanical limit switches the actuator can be configured to detect the status of the electromechanical limit switches such that the travel time between the end positions can be measured via a synchronization run.
• The travel time of the blind / shutter is automatically measured from the upper end position to the lower end position and vice versa.
• The measurement is only reliable for drives with electromechanical limit switches.
• The travel time cannot b automatically adjusted for drives with integrated electronics for disconnection at the limit positions. 
• These drives have to be controlled via a time limit.
• Their travel times have to be manually measured as precisely as possible and configured in the application program.
  
• Parallel operation of several drives on one channel requires using a special separation relay.
• If such a separation relay is connected to the output to drive several drives in parallel, then the travel time has to be configured manually.
  
• If the device is configured for automatic detection of the travel time, then parallel operation of several drives with electromechanical limit switches or mixed operation with drives with integrated electronics for disconnection at the limit positions is not permitted.
