debris and other effects that could affect the gate operation and safety.
7. On a monthly basis, check the obstruction detection system and safety devices for correct operation.
8. All repair, and service work to this product must be done by a suitably qualified person.
9. This product was designed and built strictly for the use indicated in this documentation. Any other
use, not expressly indicated here, could compromise the good condition/operation of the product
an/or be a source of danger.
10. Centurion Systems does not accept any liability caused by improper use of the product, or for use
other than that for which the automated system was intended.
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.

Gate Status Indication (optional feature)
The controller can provide visual indication inside the house of the position of the gate and the condition of the
battery and power supply. A LED is typically mounted on the intercom inside the house. The different signals of
the LED are described below:
LED STATUS INDICATION
Slow regular flash Gate is opening
Fast regular flash Gate is closing
Off Gate is closed
On Gate is open
1 Flash/2 seconds Courtesy light latched on
2 Flashes/2 seconds Mains failure
3 Flashes/2 seconds Battery low
4 Flashes/2 seconds Collision shutdown
Battery Low Protection
The controller has circuitry that monitors the state of the battery. During a power failure energy is drawn from the battery, but
not replaced. To protect the battery from being quickly damaged, the protection circuitry prevents the motors from being run
off the battery when the battery voltage drops below 10.6 volts.
Indication that the battery low protection has been triggered is provided by the small gate status LED mounted on the
intercom inside the house, which will flash three times every two seconds . The gate system is shut off for at least one minute.
After this time the gate system can be reactivated but will shut off immediately again if a battery low condition persists.
CONTACT YOUR LOCAL GATE AUTOMATION SPECIALIST OR CENTURION SYSTEMS IF YOU DISCOVER
THAT THE BATT LOW SIGNAL GIVEN BY THE LED INSIDE THE HOUSE CONTINUES TO RE-OCCUR.

system will shut down and it will not be possible to operate the gate. When the keyswitch is ON, the gate
system will operate normally.
This is an added security feature should the property be unattended for an extended length of time.
Lightning Protection
The CP75 controller has on-board lightning protection. The protection circuitry is based on a design
developed in conjunction with the CSIR. It is however important to realise that the controller's protection
only functions correctly if an adequate lightning earth is fitted during installation. Lightning damage is not
covered under the normal guarantee of the equipment.
ALTERNATIVE POWER SUPPLY
Solar Panel (Optional)
With the battery driven system, the battery may be charged using a solar panel in place of the conven-
tional charging circuit. A 20 Watt panel will provide on average 10-12 daily operations of an average gate
without causing the battery to discharge over a period of time. (The allowable number of operations will
be reduced if 12V DC security lights are fitted). It is necessary to have at least a 35A/h deep cycle, low
maintenance battery fitted, in order to provide sufficient back-up capacity during days of poor weather
All gate operators have a means of manually operating the gate in the event of a total malfunction of the
equipment.
If one is locked outside the property, the padlocks connected to the clevis pin through the gate bracket
can be unlocked. This will allow the clevis pin to be removed and the linkage arm to swing away from the
gate. This will allow the gate to be opened sufficiently to allow a person to enter.
Once inside the property, to release either operator complete the following procedure:
Connecting Arm
Gate Bracket
Bush
Clevis Pin
Swing the connecting arm to the side and open the
gate.

Unlock the padlock securing the connecting arm.
Remove the clevis pin.

To release the manual override, proceed as follows:

The CENTURION system is designed to be maintenance free. However, there are some basic checks that
should be carried out regularly (every six months) which will increase the long term reliability of the
system, and prevent false triggering of the protection systems leading to erratic operation of the gate.
IMPORTANT: ISOLATE MAINS SUPPLY TO SYSTEM BEFORE CLEANING OR WORKING ON THE
EQUIPMENT. (NB: The battery driven operators will continue to operate due to the internal battery)
1. Remove all shrubs and vegetation which may
interfere with the motors or linkages.
2. Keep the inside of the motors and control
housings clear of insects and dirt.
3. Grease the gate hinges to ensure that the gate
swings freely.
4. Check that the padlocks can be opened. Apply
oil or grease to the padlocks, particularly during
the rainy seasons.
