OPERATORS

The CENTSYS D3 and D5 Version 3 sliding gate operators are manufactured with extreme care,
thoroughly inspected and tested. The operators are only guaranteed against faulty materials or
workmanship for a period of 24 months from the invoice date of the operator, or 26 months from the

The guarantee will cover the repair or replacement at our discretion of such faulty materials or parts
free of charge, provided that the equipment is returned to our workshop.
The guarantee only applies to the gearbox, motor, controller and other components specific to the
operator. Peripheral components such as the charger, battery and other ancillary devices connected
to the operator carry the guarantee provided for these components.
This guarantee will not apply to any operator which:
a. Has been subject to misuse or which has been used for any purpose other than
designed for by Centurion Systems (Pty) Ltd

A key feature of these products is the chassis/gearbox which is moulded from a
high-tech engineering polymer. The user benefits from this material in terms of its
aesthetics, and corrosion-free properties. Due to the self-locking action of the

A revolutionary aspect of the CENTSYS range of operators is the limit switch

Most automatic gate installations are fitted with an intercom which provides for
communicationbetweenthehouseandthegate.
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 radio transmitter
describedunder“RadioTransmitter”.

the controllers for each operator are marginally different, the functions and safety

Controller features and functionsController features and functions

Automaticalignment
Automaticclosing(optional)
Autocloseoverride
CENTSYS operators are fitted with a manual override mechanism. This is to allow the
gate to be operated in the event of a total malfunction of the equipment. It is also
requiredifthemainspowerhasfailedinthecaseofthe220Voperators(A10models).
Whenacommandsignalisgivenafterthegatehasbeenmovedmanuallyandthenre-
engaged, the gate will drive to either it’s fully open, or closed, position. Referred to as
automatic alignment, the gate can only be stopped, but not reversed until the align-
mentcycleiscomplete.Thesystemwillthenreverttonormaloperation.
The system has the facility to automatically close the gate after it has been opened.
The default setting is that this facility is disabled. The time that the gate remains open
canbeadjusteduptofourminuteswherethedefaultis15seconds.
The Autoclose function can be temporarily overridden by holding down the remote
control pushbutton or intercom gate release when opening the gate, until the gate
stops. (Default setting is three seconds. It can be changed to suit.) This confirms
that the Autoclose has been overridden. On releasing the button, the gate will
continue to open fully, and remain open as long as required.
Closing the gate by using either the transmitter or intercom gate release button
resets the system back to Autoclose.

If a gate status indicator (LED) has been fitted inside the house, an additional
confirmation of the functioning of the override is provided. The status LED will
stop flashing and remain ON when the Autoclose has been overridden.
Althoughthesesystemswillcontinuetooperateintheeventofamainspowerfailure
dueto the built-in battery, itis important to register that there isa problem before the
batteryisrunflat.
The controller (CP80) monitors whether mains voltage (via the charger transformer)
is present. If not, the gate status LED, will flash twice every two seconds to indicate
mainsloss.
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 prevent the battery
running flat and being damaged, the protection circuitry shuts off the gate system
whenthebatteryvoltagedropsbelow10.6V.

Originsensorfail(A10only)
Lightningprotection
The A10 operator uses an origin switch to ensure it stops in the correct open and
closed positions. If this switch fails for any reason, the operator will shut down. To
provide indication to the user that there has been an origin sensor failure, the
status LED will flash three times every two seconds.
This condition is treated as serious and the unit cannot be activated again until the
gate has been moved manually either fully-open or fully-closed, ensuring that the
gate magnet has passed the sensor. If the sensor registers correctly, the unit will
reset, and can be operated again. If the sensor does not re-register, the unit will
remaininthelockedstate.
If the system cannot be reset by following the procedure above, it is a clear
indicationthatthe SENSOR is faulty or notswitching reliably. It is importantthat
theoperationoftheSENSORischeckedbyaqualifiedtechnician.
AllCENTSYS controllers have onboardlightningprotection.The protection circuitry
was designed in conjunction with the CSIR. Provided that the system has been
properly earthed the protection will significantly improve the resistance of the
systemagainstlightningstrikes.

Holidaylockout(optional)
Courtesylighttimer(optional)
Pre-flashing
A keyswitch 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 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 system will
operatenormally.
This is an added security feature should the property be unattended for an
extendedlengthoftime.
TheHoliday Lock out facility couldalsobeactivatedusing a keypad, radio receiver

If a 220V power supply is available at the gate, timed courtesy lights can be
connected through the controller. Each time the gate is opened, the lights will
switch on for a period of time and switch off. The time can be adjusted up to forty
minutesintensecondincrements.

ReversingMode
Condominium
Passive Infrared Autoclose (PIRAC)
Apart from the Standard Mode of Operation as described in the section Normal
Operation, the system offers another Mode of Operation. Referred to as Reversing
Mode, if the transmitter is pressed while the gate is moving, the gate will automati-
cally reverse direction. The gate can never be left in mid position with this mode
selected.
Other Modes of Operation which can be selected and operated using a radio
transmitterareCONDOMINIUMandPIRAC,whicharedescribedbelow.
The system can be programmed for “Condominium” operation. This Mode of
Operation will override the normal Mode of Operation described under the section
“Normal Operation”. This facility is designed for greater safety and security in
applications where there will be a number of users, such as the gate at a townhouse
estate,factoryorofficeparkthe“Autoclose”facilitydescribedearlier.
In “Condominium” mode “Autoclose” cannot be overridden. If the remote control or
intercom pushbutton is pressed while the gate is open the “Autoclose” will restart its
countdown. If the gate is activated while the gate is closing the gate will reopen. The
gatecannotbestoppedinamidwaypositionandwillthereforealwaysclose.
A protection beam should be used in conjunction with this facility to prevent the
“Autoclose”fromclosingthegateontoavehiclepassingthrough.
This facility is an extension of the Condominium facility described above. It is
designed for applications requiring greater security as the gate closes immediately
behindthevehicleorpersonpassingthrough.
PIRACwilloperateonlyifaprotectionbeamorothertypeofvehicledetectionsystem
(e.g.Inductiveloop)hasbeenfitted.
The remote control 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
vehicleclearsthebeamthe gatewillclose immediately,evenbefore itisfully open.If
the gate reaches the fully open position without the beam being activated the gate

CENTSYS operators are designed to be maintenance-free. However, there are
some basic checks that should be carried out regularly (every six months). These

General
Re-engaging the manual release (A10 only)
It is strongly recommended that the gate is first pushed to the fully open
position, and then to the fully closed position before the release handle is re-
engaged. This is to ensure that no untoward behavior occurs due to the
system having lost its position information.
