IntroductionIntroductionIntroduction
A CENTURION GATE AUTOMATION system is a quality product designed to give many years of trouble
free use, provided it is correctly installed and maintained.
This guide highlights the features and operation of the CENTURION R3 and R5 AUTOMATIC SWING
GATE systems to ensure that, YOU, the user will get the most from your system.
Even if you have used an automated gate before, please read through the Safety Instructions
carefully. Make sure that you fully understand the following safety requirements before finally
operating the automated gate.
Ensure that you fully understand:
How to operate the manual release mechanism. *
How the obstruction detection and all other safety features works. *
All the safety considerations associated with operating an automated gate, and that you understand
the importance of explaining these safety instructions to all other users of the automated system:
1. Do not activate your gate opener unless you can see it and can determine that its area of travel is clear
of people, pets, or other obstructions.
2. NO ONE MAY CROSS THE PATH OF A MOVING GATE. Always keep people and objects away from
the gate and its area of travel.
3. NEVER LET CHILDREN OPERATE OR PLAY WITH THE GATE CONTROLS, and do not allow children
or pets near the gate area.

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.
Principles of OperationPrinciples of OperationPrinciples of Operation

Introduction
The R3 and R5 Rotary arm operators are fitted with the CP75 controller. The controller synchronizes the
functions of the gate operator.
Modes of Operation
There are four different modes of operation that can be selected. Only one mode can be selected at any
one time.
STANDARD (with selectable auto close* feature)
REVERSING (with selectable auto close* feature)
CONDOMINIUM (compulsory auto close*)
PIRAC (compulsory auto close*)
STANDARD MODE is the most common. The other modes are usually used for specialist applications.
*The auto-close feature is described under the section “Automatic Closing”
STANDARD MODE OF OPERATION
The gates are opened in the following way:
Radio Transmitter
A hand held radio transmitter, carried in the motor vehicle, sends a coded signal to the receiver mounted
in the control enclosure to open or close the gate.
If the automatic closing facility has been selected, and the gate is closing automatically, then the gate will
stop and stay in that position if the transmitter is pressed. Pressing the button again will cause the gate to
reopen.
Features & Functions
Radio Receiver

Hand held transmitter sends coded signal Receiver uses signal to open or close the gate
Press once for approximately 1 second to get the gate into motion.
If the transmitter is pressed while the gate is either opening or closing the gate will immediately stop.
Pressing the button again will cause the gate to reverse.
If the gate is opening with the automatic closing facility selected, and the transmitter is then pressed, the
Most automatic gate installations are fitted with an intercom which provides for communication between
the house and the gate.
The intercom handset is usually provided with a GATE or DOOR RELEASE pushbutton which, when
pressed, sends a signal to the gate controller to open the gate.
The sequence of operation of this pushbutton is identical to the operation when using the radio
transmitter as described above.
REVERSING MODE
The system offers an alternative mode of operation to the above. Referred to as reversing mode, if the
transmitter is pressed while the gate is moving, the gate will automatically reverse direction. This mode
offers greater security than STANDARD mode as the gate can never be left in a midway position.
CONDOMINIUM MODE
The system can be set for CONDOMINIUM operation. This facility is designed for greater safety and
security, in applications where there will be a number of users, such as the entrance to a townhouse
estate, factory or office park.
In CONDOMINIUM mode the gate is opened by pressing the pushbutton on the remote transmitter or
intercom. If the system is re-triggered while the gate is opening, the signal is ignored and the gate will
continue to open. The gate closes automatically as per the AUTO-CLOSE facility described later in this
user guide. In CONDOMINIUM mode the AUTO-CLOSE cannot be overridden. If the remote transmitter or
intercom pushbutton is pressed while the gate is closing the gate will immediately reopen.
The gate cannot be stopped in a midway position and will therefore always close.
If the gate is triggered while the gate is in the open position, the AUTO-CLOSE timer is reset.
NOTE: It is highly recommended that a protection beam be used in conjunction with this facility to
prevent the AUTO-CLOSE from closing the gate onto a vehicle passing through.
PIRAC (PASSIVE INFRA RED AUTO-CLOSE)
This facility is an extension of the CONDOMINIUM facility described above. It is designed for applications
gate will stop, but will close automatically after the auto-close delay time.
Intercom Push button (Optional)
Press to open gate

Gate opened from intercom pushbutton inside house
requiring greater security as the gate closes immediately behind the vehicle or person passing through.
PIRAC will operate only if a protection beam or other type of vehicle detection system (e.g. inductive loop)
has been fitted.
The remote transmitter or intercom pushbutton will only open the gate. As a vehicle drives through the
entrance it activates the protection beam and as soon as the vehicle clears the beam, the gate will close
immediately, even before it is fully open.
If the gate reaches the fully open position without the beam being activated the gate will wait the AUTOCLOSE time and then re-close. If, however, a vehicle passes through the entrance activating the beam,
the gate will close the moment the vehicle has cleared the beam regardless of the AUTO-CLOSE time.
Pedestrian Keyswitch (Optional)
The pedestrian keyswitch is typically fitted to the gate pillar. Its purpose is to open the gate a limited
amount for pedestrians. In the case of a double leaf
system only the MASTER gate will open.
To allow time for removal of the key, there is a 2 second
delay before the gate begins to open. If the courtesy
light (refer section, “Security / Courtesy light timer”) is
connected to the control card, it will flash twice,
indicating that the gate will open approximately 1 metre
and then stop. After 5 seconds the gate will
automatically close.
The gate can be held open by keeping the key turned in the keyswitch. As soon as the key is released
back to its normal rest position the gate will close after the 5 second delay.
If a protection beam has been fitted (refer section “Protection Beam”), and the beam is broken while the
gate is closing, the gate will stop and re-open to the pedestrian opening point. The gate will remain in that
position while the beam is broken and only close 5 seconds, or whatever the pedestrian auto-close time
has been set to, after the beam has been cleared.
(The opening distance and the time that the gate remains open can be adjusted to suit. Default values
are described above)
Anti-crushing Device
The R3 and the R5 operator incorporates an electronic anti-crushing mechanism that will sense if a
person or vehicle has obstructed the gate.
If the anti-crushing mechanism of a single or double gate system is activated while the gate(s) are
opening, the operator of the obstructed gate will stop. The second gate in a double swing system will
continue to open. The stopped gate can be immediately operated using the remote control or gate
release pushbutton provided that the obstruction has been removed. The gate will close. (refer point
regarding multiple collision below)
In the case where the gate(s) are closing, both gates will re-open if the anti-crushing mechanism is
activated, regardless of which gate is obstructed. As per the above, when activating the system again,
both gates will close.
