Your Sliding Gate: What You’ll Need

Unless you possess the power of teleportation (in which case we’d like offer our thanks for reading our modest newsletter, oh visitor from another world), chances are that you gain access to your property by means of a point of entry enclosed by walls, or “gate” as we sometimes like to call it (as an interesting aside, the word “gate” derives from the old Norse word gata, meaning road or path). But, perhaps you only recently had the fence or wall erected and it as yet sans gate, or you have simply decided to automate an existing one. Then, dear reader, it is important to know what kind of hardware you’ll need and what function it performs, lest you end up with a gate that is either recalcitrant or, even worse, unsafe. Fortunately, we’ve been in the gate automation business for going on 30 years and we’re channelling that experience towards guiding you in any-gate related endeavours that you may wish to undertake.
Here’s what you’ll need:
Guide-rollers

Guide-rollers do exactly what their name suggests, they guide the gate. In other words, the guide-rollers – which are normally just two nylon rollers that rotate on shafts – hold the gate vertically and prevent it from falling over which is, you know, something you’d want to avoid if possible. For improved safety, we recommend fitting additional support posts to prevent the gate from falling over should the guide-rollers fail.
Anti-lift Brackets
Again, the job description is more or less in the name here. Anti-lift brackets help prevent unauthorised access to your property by ensuring that the gate can’t simply be lifted off its track by some devious criminal/strongman combo (of course, most gates are light enough not to require a strongman to lift it, hence the need for anti-lift brackets).
Endstops
Endstops are very important from a safety point of view and prevent your gate from abandoning its track. Remember that there is always the chance, however remote, that the gate will overrun its limits (and we’d like to point out here that with our new generation of gate motors, the chance is even more remote since the operator will always look for the origin magnet and will run the gate slowly if it is not detected), and you don’t want the gate behaving like a runaway train with nothing to stop it. CENTURION recommends installing mechanical endstops that are sturdy (preferably welded onto the track) and do not move even when subjected to considerable force.
Wheels
The movement of your gate depends largely on the presence of a collection of spherical objects that rotate about a shaft, or “wheels”. Keep in mind that the entire weight of your gate will rest upon the wheels, so it’s important to keep them in a good condition and rotating freely. They will also need to be compatible with the profile of the rail. CENTURION stocks both U- and V-profile gate wheel kits, as well as the novel GateShox system which dramatically reduces noise in sliding gates. Over time, the rails of sliding gates can become corrugated and uneven from use, and GateShox help absorb the load through a spring system, resulting in a smoother ride and quieter operation.
Rack
If you’re planning on automating your gate (and, let’s be honest, it’s the logical thing to do), you’ll need a toothed rack fitted along the length of the gate to mesh with the pinion of your gate motor. The setup works in an almost identical fashion to the rack-and-pinion configuration found in the steering wheel mechanisms of most cars and, depending on which operator you’re planning on having installed, you’ll need either Raz, nylon angle or steel rack. Not sure which one? Give us a call on +27 11 699 2481 for some friendly advice.
A Reliable Gate Motor
We previously likened buying a new gate operator to selecting a new car. Considerations such as the weight of the gate, maximum number of daily operations, push force and duty cycle all need to be taken into account when choosing an automation system. But, most of all, it’s important to ensure that you choose a gate motor that will never leave you out in the cold, so to speak. CENTURION manufactures a wide range of reliable swing and sliding gate motors for domestic, light industrial and full industrial applications. Our operators are constructed from only the most robust materials in accordance with the ISO9001 quality assurance system, and carry a 24 month warranty.

Automatic Gates

Automatic Gates

An automatic gate can make accessing your property a secure, safe, reliable and easy process and will give you many years of trouble free service if designed and installed correctly in the first place.The advantages of an automated gate are obvious. Security, convenience, style and safety, and while there are many different types and automatic solutions available for gates, we can help with the best combination for your residential or commercial property.

 

Swing Gate.Image

If space is not an issue double and single swing gates are the best option with a swinging gate generally being safer than a sliding gate. When considering the option of a swinging gate it is important to consider the size of the gate and its movement or operation area. A single swinging gate can be as large as 3 meters wide or up to 6 meters as a double swing with its operation area normally 90 degrees inward. In a situation where the gate position is on a slope the ideal movement should be toward the lower side of the slope to prevent collision between the gate and the ground and to allow smooth operation

Slide Gate

Image
Sliding gates are an ideal automation option, especially when a swing gate is not possible. We would recommend a sliding gate where space is limited in some way (landscaping, boulders, etc.) or the area is required for parking. Sliding gate require storage area. This is the area that the gate slides into when it is in the open position, making the movement area and the entrance area double the size of the actual gate. Sliding gate require a level ground upon which to slide however with the right type of sliding gate operator a slight slope is acceptable. Sliding gate motors are designed to neatly fit behind existing walls or fences, without compromising space within your property.

AUTOMATED GATE SAFETY

Automated Gate Safety

 In an era not too long ago, siblings were engaged in fiery arguments in the backseat – arguments that bordered on full-on combat – about a very important issue of the day:  Who was going to open the gate when they arrived home?  The hapless father would grip the steering wheel tighter, his knuckles whitening around it and beads of perspiration already forming on his forehead in anticipation of the skirmish that would no-doubt erupt when they eventually pulled up to the driveway.

Gate automation changed all that.  Nowadays, opening your entrance gate is as simple as pressing a button on a remote – and brothers and sisters once again live in harmony. Modern access control has put at our disposal a world of convenience, an exciting universe where everything around us can be set in motion at the press of a button.  We are firmly in control of our surroundings.

However, as with any automated system, safety is paramount when it comes to automating your entrance gate.  As a leading South African manufacturer of gate automation and access control equipment, it is our distinct privilege to be able to share some guidelines for a safe installation.     

1.       Endstops

Many modern gate operators make use of a current spike to stop the gate in the correct opening and closing positions.  In other words, when the operator is commencing the limit setup procedure, encountering an obstruction will induce a current spike which tells the controller that this is where it must henceforth stop the gate.  If no mechanical endstops are installed, no spike will be read and the gate will just keep on running and could potentially come off its rail – with disastrous consequences.

Endstops should be fitted in both the opening and closing positions, should be constructed from a robust material such as steel, and must remain fixed even when considerable force is applied to them.  It is therefore advisable to weld them in place.


2.       Guide-rollers

Guide-rollers are at least as important as endstops, as these devices are what quite literally keep your gate on the straight and narrow.  Without guide-rollers, your gate would wobble drunkenly from side to side and eventually come crashing down like a felled animal.  It doesn’t take a giant stretch of the imagination to envisage the damage to property or injury to person that would result from such an incident. 

3.       Electrical Safety

Always have a qualified electrician attend to any high-voltage (higher than 50V) electrical needs that may arise from installing a gate operator.  Depending on where you live, you may also be required to fit an isolator within arm’s reach of the operator.

Take care not to short out battery terminals, and ensure that all electrical equipment is sufficiently earthed, as this will help prevent damage to the devices as well as electrical shock.


4.       Sensitivity Settings

Any gate motor worth its salt will have adjustable sensitivity settings.  While it is at times desirable to have a lower setting to compensate for environmental changes such as wind loading (applies more to swing gates) or variations in the track, it is important to remember that the lower the setting, the harder it will be to stop the gate.

5.       Prevent Unauthorised Access

Kids (and some adults) are curious.  That is a simple fact of life.  But curiosity can quickly turn to tragedy if proper care isn’t exercised when it comes to securing gate motor controls. Ensure that only authorised adults have access to the controls.  Operator covers should at all times be locked in place and the keys kept in a safe location.  

6.       Keep the Area of Travel Clear!

This is arguably the most important guideline of all.  

No matter how cautious one purports to be, no matter how vigilant, accidents do happen. Therefore the best course of action is, before attempting to operate an automated gate, to first ensure that no children or pets are in the vicinity.  A Courtesy Light can also be installed to provide visual indication prior to and during gate travel.

The Virtues of the VECTOR2

The Virtues of the VECTOR2

 

“Innovation distinguishes between a leader and a follower” – Steve Jobs
The VECTOR2 linear swing gate operator is, to put it bluntly, a leader. It leads (confidently, one might add) in terms of design, in terms of intuitiveness and in terms of ingenuity. Let us not forget that not too long ago swing gate motors still relied upon micro-switches for position control and offered precious little by way of functionality. If you wanted any special features such as an extended automatic closing or a wider pedestrian opening, you’d have needed to order a custom-programmed microchip.

Archaic!, you say. Barbaric even. Be that as it may, until quite recently swing gate motors were mere pistons working mindlessly to provide only the most rudimentary of automation solutions.

Even in today’s intensely technology- and convenience-driven milieu, very few operators truly stand out in terms of intelligence. 

The VECTOR2, however, is quite different as you’ll soon discover; for within its LCD controller – one that is no larger than an average hardcover novel – is housed the sort ofintelligence that has the power to redefine an entire industry. Every facet of the VECTOR2operator’s firmware has been designed to be intuitive to the point of precognition, even adapting its behaviour to accommodate any hardware variations that it encounters.

What follows are some examples of how the VECTOR2 makes life easier for installer and end-user alike.

It Practically Wires Itself


As a general rule, there is a hard and fast way that any given device needs to be wired in order for it to work and, when it comes to gate automation, incorrect wiring could very well metamorphose your beautiful wrought-iron gate into the world’s frilliest wall.

So, does the same bleak fate then await you, oh VECTOR2 owner, if you happened to inadvertently wire, say, your master motor’s sensor wires to the slave motor’s sensor inputs on the controller? Will the operator start moving drunkenly back and forth, unable to determine whether it is the master or the slave?

Nein.

The VECTOR2 controller is intelligent enough to pick up on this little miscalculation and rectify it electronically, saving you the time and effort of spending countless hours trying to trace the fault. It is entirely possible to mix channels in this fashion without adversely affecting the operation of the gate.

State of the Art Position Control

The VECTOR2 makes use of a double-redundant opto-electronic system for position control which, in layman’s terms, basically means that the controller always knows exactly in which position the operator(s) is/are. So intelligent is this system, that it even counts pulses if the gate is moved with the operator in the disengaged state.

But what is the benefit of this?, you ask.

Well, let’s say that a leaf delay of 20mm  is active because an electric striker lock or mechanical lip necessitates one gate closing before the other. This scenario in itself would not normally pose a problem. 

But imagine, if you will, the following conundrum: your gates have somehow fallen out of synchronisation. Perhaps you were doing some maintenance on your master gate that necessitated disengaging the operator so that you can move the gate around freely by hand. The problem might now arise that the master gate is now closer to the fully closed position than the slave – and remember, with leaf delay enabled the slave always closes before the master.

Or at least, this would have been a problem were it not for the aforementioned opto-electronic system.  In a situation such as this, the VECTOR2 controller will keep the master stationary and move the slave past the master until there is a gap of precisely 20mm of piston stroke between them. Upon this gap being achieved, the master will be activated and the desired leaf delay will be intact. 

Fully Intuitive Setup

Traditionally, the only way to get a motor to reverse direction (i.e. to change from, say, in an inward opening configuration to an outward opening configuration) was to swap the motor wires around; especially in a double-leaf swing installation, this made for rather a hairy setup procedure. Fortunately, the VECTOR2 controller possesses the ground-breaking intuitiveness to automatically detect in which direction the gate should be opening – as well as which gate it should attempt to open first during the setup – and reverse the wires electronically. 

So space-age is the technology inherent in this controller, that if it is unable to move one gate in either direction, it will automatically detect that perhaps it is trying to move the incorrect gate and not only swap the motor wires electronically, but effectively swap channels! This sort of fully automated process saves valuable time onsite.

In conclusion, one can surmise that the VECTOR2 linear swing gate motor is truly a marvel of modern engineering and ingenuity; its sleek, slim line design, easy-to-install construction and fast operating speed rivalled only by the incredible intelligence housed within its controller.

Photon Sees the Light! Centurion Wireless Infra-red Beam

Photon Sees the Light!

 

You know that excited, almost electric feeling that’s in the air right before a summer storm on the Highveld? Like every atom and molecule is abuzz with activity, like the very air around you is alive?
Well, I can tell you in no uncertain terms that this was the kind of atmosphere around the CENTURION office earlier today as we prepared to announce the release of Photon – ourbrand new infrared gate safety beams with a wireless transmitter.

Photon officially became available for purchase from CENTURION and its agents on Valentine’s Day, 14 February 2013, a day that will go down in history as the day that automated gate safety became easy.

Image
But before we go into what makes Photon so awesome (and trust us, it is AWESOME), let’s have a recap of why you need gate safety beams installed in the first place. Think of it as Gate Safety 101.

It’s quite simple, really: You wouldn’t drive your car without wearing a safety belt (we hope not, at least), and you won’t jump out of a plane without a parachute, so it stands to reason that you shouldn’t let your automated gate run without putting some measure of safety in place, either. As we have stated in many previous articles and posts, an automated gate – wonderful and convenient as it may be – is still a mechanical system and as such carries with it the risks normally associated with moving parts. 

Infrared beams have been found to be the most effective means of protecting against crushing, dragging and shearing in an automated gate setup. They are relatively inexpensive and are for the most part reliable but, due to the high cost of installing them – a result of having to route metres of cable, often under driveways – many installations have thus far simply gone without. It is also understandable to a degree that many homeowners would be hesitant to have their driveways defaced for this purpose.

That’s where Photon comes in.

As mentioned before, Photon has a wireless transmitter so the only wiring necessary is from the receiver to the gate motor and, with the receiver traditionally being mounted closest to the motor, no digging or tunnelling is required. As Photon’s slogan declares: Simply attach, align and you’re away! 

Photon also boasts brand spanking new operating features such as Installer Mode: a Mode of Operation that makes the installer’s life that much easier by providing a 4KHz tone once alignment of the beams is obtained, taking all the guesswork out of installing beams.

Then there’s also Open Collector Mode, a feature tailor-made for sites where power draw is a factor (think solar powered installations). In this mode, the receiver relay is disabled and switching is done via a transistor, bringing the overall power consumption on the receiver’s side down by about half.
