Introduction
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.
Safety Instructions
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.
Page 4
4. Be careful with moving parts and avoid close proximity to areas where fingers or hands could be
pinched.
5. Secure all easily accessed gate opener controls in order to prevent unauthorized use of the gate.
6. Keep the automated gate system properly maintained, and ensure that all working areas are free of
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.
Principles of Operation
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.

Features & Functions
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 Receiver
Hand held transmitter sends coded signal
Receiver uses signal to open or close the gate
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.
 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 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.
Page 6
If the gate is opening with the automatic closing facility selected, and the transmitter is then pressed, the
gate will stop, but will close automatically after the auto-close delay time.
Intercom Push button (Optional)
Press to open gate
A visitor outside the gate requests entrance
Gate opened from intercom pushbutton inside house
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
Page 7
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.
RELEASE

TURN
Fit key into keyswitch and turn key clockwise as
though starting a motor car.
Let the key spring back to rest position and remove
key immediately.
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.

Pedestrian Keyswitch
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.
Page 8
Gate opening onto an obstruction
Only the obstructed gate stops.
Gates closing onto object.
Both gates automatically re-open.
MULTIPLE COLLISION
If the system is obstructed repeatedly 4 times after the initiation of an opening cycle, and before the
master motor gets back to its fully closed position, the gate(s) will stop and remain locked in position for 1
minute. After this time the gate can be restarted. This function is a warning to the user that the obstruction
must be removed.
The “collision counter” will reset to a count of zero when the master gate is fully closed. The number of
collisions that must occur before shutdown is activated is adjustable from 1 to 255.
Automatic Closing
The system has the facility to automatically close the gate after it has been opened. The time that the gate
remains open is adjustable from 1 to 255 seconds. The factory default is 15 seconds when the facility is
switched ON . By default the auto-close function is off.
Page 9
AUTO-CLOSE OVERRIDE
INTERCOM PUSHBUTTON or REMOTE
Press and hold the gate
release for 3 seconds to
override the auto-close.
If the auto-close function has been selected it can be conveniently and easily overridden for one cycle.
This override feature is activated by holding down the remote control push-button, or intercom gate
release button (approximately 3 seconds), when opening the gate, until the gate stops. This confirms that
the auto-close has been overridden. On releasing the button the gate will continue to open fully and
remain open indefinitely.
Closing the gate by using either the transmitter or intercom gate release button automatically resets the
system back to auto-close.
If the status LED (refer to section GATE STATUS indication below) is connected, an additional
confirmation of the functioning of the override is provided while the button is held down. The status LED
will stop flashing and remain ON when the auto-close has been overridden.
Protection Beam (optional
but recommended)
An infra red beam, or underground loop
(connected to an inductive loop detector), across
the gate entrance may be connected to the
controller as an additional safety feature. For
optimum protection when using infra red beams,
two sets of beams should be used; one on the
hingeline of the gates and the second just outside
the arc of the gate travel.
When a motor vehicle activates the loop or beam
the following occurs:
 If the gate is closing, it will immediately stop and re-open.
 If the gate is open, and the beam is broken, a trigger signal trying to close the gate will be ignored.
 If the AUTO-CLOSE feature is selected, the gate will remain open while the beam is broken or loop is
activated. If the beam or loop is cleared the gate will only close again after the normal auto-close time
has expired.
Page 10
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

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.
Status LED
Status LED location on the CP75 Controller Card
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.
Page 11
If the gate status indicator has not been fitted, there is an equivalent LED mounted on the CP75 marked
STATUS, which can be used as a fault finding aid.
NOTE: The controller's battery low protection will ensure that only the motors are prevented from
drawing current from the battery. Items such as the radio receiver, Infra red beams etc continue to
flatten the battery. An optional battery low cut-out switch (product code CP107) is available which
will totally disconnect the battery.
Security (Courtesy) Light Timer (optional feature)
If a 220V power supply is available at the gate, timed security lights can be connected through the
controller. Each time the gate is given a signal to operate, the lights will switch on for approximately two
minutes and automatically switch off. The time that lights
stay on can be programmed from 10 seconds to 42
minutes in increments of 10 seconds.
If security lights are fitted to the controller, and the
pedestrian keyswitch is operated, the security lights will
flash twice before the gate opens. (the preflash time is
adjustable)
A pushbutton can be connected to the CP75 controller
which will allow the pillar/courtesy lights to be switched
from inside the house without having to operate the gate.
Typical Security or Courtesy Light Installation
The pushbutton switches low voltage, and the spare
pushbutton provided on many brands of intercom
handsets can be conveniently used.
When the pushbutton is pressed momentarily the pillar lights will switch ON for the pillar time period and
switch off automatically. If the pushbutton is pressed and held for approximately 4 seconds, the pillar
lights will stay on permanently. The lights are switched off by simply pressing the pushbutton again. If the
gate status indicator is fitted to the intercom handset, it will flash once every two seconds to indicate that
the pillar lights are ON permanently.
Low wattage 12V DC light fittings are also readily available and can be connected to the system, drawing
power directly from the battery. Care must be taken to ensure that the power drawn from the system by
lights and the motors does not exceed the re-charge rate of the CP84ER5V01 battery charger. A larger
charger unit should be fitted to cope with the additional load.
Pre-Flashing
For additional safety, the courtesy light can be programmed to provide an early warning that the gates are
about to operate. When the gates are activated the lights will flash for 2 seconds before the gate starts to
open or close. The courtesy light timer will still function as normal only in certain modes. (the pre-flash
time is fully adjustable in 1 seconds increments. The factory default is 2 seconds). By default pre-flashing
is OFF.
Holiday lock out (optional feature)
An ON/OFF keyswitch (or any other convenient apparatus such as a keypad or radio receiver) can be
connected to the gate system that will allow the system to be totally immobilised. The keyswitch is
mounted with access from the outside of the property. When the keyswitch contact is OFF, the gate
system will shut down and it will not be possible to operate the gate. When the keyswitch is ON, the gate
Page 12
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
conventional 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
Manual Release
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:
NB: DO NOT OPEN THE COVERS WHEN EXPOSED TO DIRECT RAIN. ALWAYS SHIELD THE
UNIT WITH AN UMBRELLA.
Unlock the padlock securing the connecting arm.
Remove the clevis pin.
Swing the connecting arm to the side and open the
gate.
Page 13
To release the manual override, proceed as follows:
Unlock and remove the operator cover.
Lift the controller housing fitted to a MASTER motor.
This is not necessary when releasing a SLAVE motor.
Swing open the manual release dust cover.
Insert the allen key provided into the manual release
mechanism and rotate it clockwise to release the
gearbox (approximately 12 turns)
Page 14
To re-engage the drive (disengage manual override):
Unscrew the allen key (counter-clockwise) until the
top of the screw is flush with the top of the shaft.
Rotate the dust cover back into position.
Lower the controller housing into position (not
necessary for a SLAVE motor)
Replace the operator cover and lock it in position.
Page 15
Basic Maintenance
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.
Page 16
Battery
All CENTURION domestic systems are fitted with a maintenance free lead acid battery that should
provide at least three years of uninterrupted operation.
In the case of a 35A/h battery ensure that the level of liquid (electrolyte level) is correct.(NB: Due to its size
the 35A/H will be housed in a separate enclosure).
Check for corrosion of the battery terminals. Clean and apply grease as necessary.
CP75 Controller
Battery 12V 7A/H
CP84ER5V01 Charger
Fuse(250mA Size 5x20mm)
Battery Charger
In domestic applications the R3 and R5 are battery driven. Each system has a built in battery charger
which automatically maintains the battery in a fully charged state. The casing may get hot when the
charger is in operation. This is quite normal and is no cause for concern.
The small green light (LED) on the CP75 controller marked CHARGER ON should be illuminated at all
times. This light indicates that the electricity supply from the charger unit is switched ON. NB: It does not
indicate that the charger is charging correctly and therefore it is good practice to have the charging rate of
the unit checked from time to time. This is particularly important in areas which are prone to lightning or
mains supply surges.
Specification of Charger:
No load charge voltage (measured at battery terminals with battery disconnected) 13.6 to 13.8 volts DC
Charge rate under full load - +/- 1 amp.
Solar Panel
Ensure that the panel is cleaned regularly; excess dirt, dust and leaves collecting on top of the panel will
reduce it's efficiency. Cut back any vegetation or trees that are shielding the panel from the sun.
