The CENTURION R3 and R5 rotary swing gate operators are both powered by a 12V DC motor using a
maintenance free, lead acid battery as the primary power source. The battery is charged via a 220V mains
supply or a solar panel. The major benefit of this philosophy is uninterrupted operation of the gates even
in the event of a mains power failure. For light industrial applications the R3 and R5 operators are both
available with a power-pack which can deliver the full current draw of the 12V DC motor. If battery back-up
is required, a battery is fitted in a separate enclosure. The capacity of the battery is determined according
to the number of operations required in the event of a power failure.
An independent motor drive unit operates each leaf of the gate. Both single and double leaf systems are
available. The MASTER operator and the SLAVE operator where applicable consist of a high torque
geared DC motor driving through a main reduction unit onto an output shaft. The output shaft is linked to
the gate via an articulated arm secured by a padlock. The drive units are self-locking preventing the gates
from being forced open.
The electronic controller, charger and maintenance free battery (7A/H) are housed inside the MASTER
motor of the system only. The electronic controller, which co-ordinates the operations of the drive units, is
further protected by a plastic enclosure inside the MASTER operator. For added reliability the controller is
fitted with advanced lightning protection based on circuitry, designed and tested in conjunction with the
CSIR.
The drive unit uses an innovative internal position control system with origin, to track the movement of the
gate and accurately set the "open" and "close" positions.
Each operator are fitted with an internal manual override release.
