Modular: bars are easily assembled using the aluminum expansion joint. Possibility for intelligent control of two opposing operators thanks to “master/slave” function. Strength and reliability: robust structure in steel, new high strength balancing springs, and elliptical section bar with high wind-gust resistance. Optional flashing or traffic light can be integrated in cover. Encoder movement control and electromechanical limit switches. More comfort and safety in programming and maintenance: the separate enclosures for electronics and mechanics protect internal parts from potential risks. Rapid and easy access to the control unit located in the upper section of the barrier body. Specially designed enclosures allow simple attachment of photocells to the barrier operator cabinet. More safety and reliability: obstacle detection and monitoring of motor current during automation movement. Automatic fault diagnostics during operation with consequent signaling of fault type through specific flash sequences. Provision for connection of latest generation optical and resistive sensitive edges (with 8.2 KOhm resistance).Energy saving: the system sets to standby when not in use to lower power consumption. No blackouts: emergency backup power with the optional batteries housed inside the case. Release from side with metal key, can be installed on either side.
