Gate Motor Batteries – What you need to know

Your Gate Motor

If you own any of the top major brands you probably wonder why your gate does not work even when there is power? Well, your gate motor needs the battery to function. The mains power feed to it is only to keep the battery in a fully charged state – The battery is a lead acid battery, like a car’s battery. And below is how a startup battery (yours) and deep cycle battery stores and uses power.

Energy storage terminology

At their core, batteries charge and discharge electricity. A great analogy for batteries is a water pitcher. When the pitcher is being filled with water, it is charging. When the pitcher is pouring out the water, it is discharging. In energy storage parlance, this process of a single charge (i.e., filling the pitcher) followed by a single discharge (i.e., emptying the pitcher) is called a “cycle”.

Two other key terms to understand before diving into deep cycle batteries are depth-of-discharge and the state-of-charge. Depth-of-discharge is a metric for how much of the battery’s electricity you’ve used, while the state-of-charge is a metric for the amount of electricity remains stored in the battery. Using the same water pitcher analogy, if you were to pour out only three-quarters of the water pitcher, the depth-of-discharge would be 75 percent while the state-of-charge would be 25 percent.

There are a lot of terms and jargon associated with batteries. To learn more about relevant terminology, check out our energy storage glossary.

Deep cycle batteries vs. starting batteries

There are two main distinctions between types of batteries, each appropriately named for the situations when they are most useful: 

Starting batteries and Deep Cycle batteries.

Starting batteries are used for turning on appliances, such as lighting or a car’s ignition. These types of batteries provide a very large amount of power over a very short period of time to get an appliance (or car) up and running.

Deep cycle batteries, on the other hand, produce a smaller amount of energy but are able to do so for a very long period of time. The nomenclature of deep cycle batteries comes from the fact that they are designed to be discharged as fully as possible each time they are used, a “deep-cycle” of the battery. Whereas discharging a starting battery fully can decrease the lifetime of the battery, discharging a deep-cycle battery fully is exactly the battery’s intended purpose.

Best applications for deep cycle batteries

The nature of deep cycle batteries is to provide a consistent source of energy over a prolonged period and to be frequently fully charged and discharged. As a result, that makes deep cycle batteries ideal for pairing with renewable energy resources and home energy storage applications. In particular, deep cycle batteries are a perfect complement for solar energy. While the sun is shining during the day, deep cycle batteries can store generation from your solar panels. When the sun goes down, you can use the electricity stored in the battery to power devices in your home. And then, when the sun comes up the next morning, your partially- or fully-emptied battery will be ready be charged anew by the electricity generated by your solar panels.

As opposed to starting batteries, which are meant to never be discharged fully and are only intended to provide an initial kick-start of power for other systems, deep cycle batteries are ideal for home energy storage purposes. For the most part, home energy storage systems must be capable of providing a steady amount of electricity over a period of several hours – exactly the service provided by deep cycle batteries.

Garage Motor Battery back up ready for load shedding

battery pack for centurion rdo roll up garage door motors

Load shedding is the worst and products were not designed to accommodate, especially Roll Up garage door motors. They have small batteries with small capacity at very slow charging rate.

The problem is, our battery backed up devices cannot charge to full capacity between power outages, for 2 hours back up power a standard system will take around 16 hours to charge back to full capacity. My solution to my clients.

a Standalone battery pack with 8x more power storage capacity and 8x faster charging rate. Also I’ve added a charging module, disconnecting the charger when batteries are charged to capacity.

Gate motor Batteries SLA & Lithium Batteries for gate motors?

Lithium battery for gate motors

Is this another gimmick to part you from your hard earned money? Let’s dig a little deeper.

No documentation to support any claim whatsoever. Yes, these batteries are used everywhere but they all have operating conditions. These are way more dangerous than lead acid batteries. When used outside of conditions they do catch fire all on it’s own. FACT!

These Lithium batteries are expensive, to maintain the battery you will need a charger suited for the specific battery you have or planning to get.

Use it in your gate motor? I would not recommend it.

  1. Lets take the charging cycle of a normal Lithium-ion battery – 15.2 – 15.5 vdc. a Standard domestic sliding gate motor with SLA battery voltage is between 14.2 and 14.4. This is not sufficient for Lithium batteries
  2. Gate motor battery leads are equipped with 4-5mm terminal lugs – Lithium batteries need 10mm – big reason for that. 

In short Know your power storage needs – a very good expensive battery is just expensive if you have no idea how to keep it good. Take your time, do research, allot. And buy what you need – lithium batteries in gate motors will only perform better with the correct charging system.

Rather – replace your charging system to something that will charge your 7ah battery full in 2 to 3 hours

a Snippet from another blog

Can I charge my lithium battery with a lead acid charger?

Detailed answer: Lithium batteries are not like lead acid and not all battery chargers are the same. A 12v lithium battery fully charged to 100% will hold voltage around 13.3-13.4v. Its lead acid cousin will be approx 12.6-12.7v.

A lithium battery at 20% capacity will hold voltage around 13V, its lead acid cousin will be approx. 11.8v at the same capacity.

So if you use lead acid charger to charge your lithium battery, it may not be fully charged.

You can use a AC to DC lead acid charger powered from mains power, as charge efficiency and duration are less of a concern, it must not have automatic de-sulphation or equalization modes. If it does, do not use it as there is a high chance of damage to the cells or battery. This can have significant reduction in battery longevity. If it has a simple bulk/ absorption/ float charge profile, then it can be used to recharge the battery but must be disconnected once charged and not left in trickle charge/maintenance mode. It must also have a maximum output voltage of 13v-14.5V. When it comes to DC- DC chargers and solar controllers, you must change these to LiFePO4 specific models.

Taking Photographs

I take pictures before I start. – this way I can study them later and I’ve been taking photos about things ever since I knew how to load a 35mm film camera – along the years I developed a skill other than fixing stuff and taking perfect photos, I can tell by just looking at it what the problem is.

Realizing we all see different things.

My job is to fix this garage door operator. So I won’t be paying attention to the spiders, grease, dust and stuff I can trip over. 

Images below will be better if you read 1st and then click to enlarge.

#1

Assess & Repair or Quote to repair.
Make: Digidoor
Model: II (220vac) Powerhead designed to be installed horizontally in an overhead hanging way.
Extrusion: 2.2m Designed for tip up doors combined with said powerhead.

Quick analysis. This setup is born to fail and be unreliable. I cant fix a modified installation – I can salvage it to run again, no problem, and this is why I wont be able to warrant this repair.

 

#2

Closer look into why it failed. – Remember design? Horizontal and this vertically installed. Hanging stuff only goes one place on its own, and that is down!
By installing this extrusion in a vertical manor, meant the closed run time limit sensor will be exposed to gravity, cleaners, kids, balls, cars, floods and spiders.

#3

Do you think that wire is important? It is, but why is it just hanging around and broken, how does it just break?

I get these questions from clients yes.

Answer: (refer to #2)

 

#4

Closer look into why it failed. – Remember design? Horizontal and this vertically installed. Hanging stuff only goes one place on its own, and that is down!
By installing this extrusion in a vertical manor, meant the closed run time limit sensor will be exposed to gravity, cleaners, kids, balls, cars, floods and spiders.

And this is what happened.

  1. Open position run time limit sensor cable damaged – can only geus how
  2. Pushing past this sensor the motor jammed on obstruction
  3. Obstruction sensors failed to stop the motor when hitting obstruction.
  4. Causing the whole obstruction sensitivity mechanism to collapse and break.

#5

All the damage here was cause by wrongful installation, the white ring mark is where the drive pully is catching the powerhead. and the yellow block holding the power head to the extrusion is broken.

 

 

Sliding gate wheels replaced

Gate wheels are important

a damaged or worn wheel puts excessive wear and tear on your gate motor and will damage it very quickly. 

Sliding Gate Wheels

New Gate wheels fitted

The new gate wheels I installed were done to be frictionless, friction is no ones friend.

Doing the Job

I can’t even…..

Doing the job right

Taking a bit more care and feeling proud about the little things. IRemoved over 2,5kg excess metal from this gate.

Gate wheels caused the damage

This wheel was caused a Gemini DC slider to heat up and draw so much current it would drain a new battery after the 3rd operation.  

Taking no chances

Replaced the following, wheels, Gemini SEL pcb and the battery. Doing this I am able to assure longevity of the motor.

Ready for another price hike?

Information Bulletin
Our dearest client,

We write to you with the year of 2021 nearly coming to an end.But regrettably it is not marking the end of an inexorable rise in costs that is plaguing almost all manufacturers in South Africa.The worldwide boom in commodity prices has certainly been great for this country as a net exporter of commodities, but out of all these commodities comes materials required for the manufacture of our products. Materials such as steel, aluminum, engineering plastics, copper wire and the list goes on.Layered on top of this has been the unparalleled increase in the cost of electronics components exacerbated by a total shortage of supply. Shipping in all these components from the various countries of supply has also been subjected to massive price hikes. As an example, the cost of a 40ft container out of the Far East has gone from approximately R60,000 a couple of years ago to over R200,000 today.We are trying to absorb all these increases along with our local increases in the cost of labour, electricity, etc. as much as possible, but regrettably we need to pass on a small increase of 2.5%, over and above the increase applied earlier this year.The new prices will come into effect from the 1st November.
Kind regards,

The CENTURION Team

Gate Motor Scam

Our Public is being fooled again by dodgy gate motor installers. They are being sold refurbished (2nd hand) Centurion D5 Evo Gate motors “as new”

The Unit are nicely seal by centurion systems but have a red label indicating it’s a refurbished unit. Our public does not no this and are being fooled into thinking it’s new.

Be aware – If you are getting a “new” motor at half the price. It’s not new.

Frequent gate motor questions

Why use DC motor or battery operated motor on a gate opener?
What is the biggest gate that can be operated with the D5-Evo / D5 / D3 / A5?

The limitations for the A5/D5 are the following:

  1. The starting pull force must be less than 25kgF for the D3, 60kgF for the D5 and less that 22gkF for the A5.
  2. The mass of the gate must be less than 300kg for the D3 and less than 500kg for the D5 and A5 motors.
Why does the A5/D5 sometimes seem to lose its endpoint setting? (Refers only to version 1 type D5 or A5 motors)

The most likely cause is loss of mesh between the rack and pinion. Because of the internal limit switch mechanism (DOSS) it is vital to maintain the mesh between the rack and the pinion.

My A5 motor stops intermittently for no apparent reason. Sometimes it stops during opening and sometimes during closing.

The problem may be caused by a loose connection in the controller 12V DC power supply circuit. What happens is that the controller momentarily loses its 12V DC supply (it is often a drop in voltage that occurs so quickly that it is not possible to measure it with a standard volt meter) and the P/C microprocessor on the controller resets. It is very easy to see if this is the problem because the STATUS LED flashes 5 times as the motor stops, and all the monitoring LED’s (STATUS, L1 AND L2) will be switched off.

Centurion D5 Smart

In my opinion.

GATE MOTOR – d5 smart

My thoughts on the D5 Smart after 1st installation.

It is a small’ish motor, fits directly onto the D5’s baseplate and I like that.

I did not like the “Update” or ” “Sync” procedure. It Requires internet connectivity on your phone – It takes a while too. So if you find yourself in a remote area with poor connectivity you will not be able to get this machine going.

I like the height adjusting feature – not just for leveling but now to align with rack.

I also liked the fact that it does not make use of an origin marker, safes time and eliminates future headaches.

The “App” is cool, but the lady talking is annoying.

Let’s talk specs, pretty much the same workhorse ability as the D5 Evo coupled with double the speed – It’s Fast, really fast. Safety beams are strongly suggested. Because of this speed it will need a maintenance checkup every 3rd month, you forget, you pay.

Accredited By Centurion Systems

I have attended training and passed with flying colours and have the certificates here. Is your installer trained to work on your gate motor? Remember – It’s all about security.

Centurion to the Test

Centurion to

Mother Nature is a notoriously fickle – and at times downright ruthless – dame. While she may occasionally do something whimsical like giving us a monkey’s wedding, there are also times that it’s quite evident that she’s had a fight with her boyfriend or something. This year especially was fraught with meteorological curve balls including, but not limited to, tornadoes. Freaking. Tornadoes.It’s also starting to become pretty clear that Al Gore was onto something with the whole global warming thing. According to NASA’s Goddard Institute for Space Studies, Earth’s overall temperature has increased by 0.8°C since 1880. While this may seem insignificant, the effects are dramatic and far-reaching and, regrettably, climate change is showing no signs of slowing down.

While there’s not too much that we can do about the weather, we can set your mind at ease by telling you thatCENTURION products have been designed to handle very extreme environmental conditions.According to senior electrical engineer Tony Baia, reliability as a design philosophy and something to be sought with relentless fervour has been ingrained in CENTURION’s DNA since the very beginning.

“From its inception,” begins Tony “Centurion Systems’ founding fathers and design engineers understood that, to ensure the reliability of its now-famous D5 [sliding gate motor] and other electronic products, they had to tame one of nature’s most awesome and powerful phenomena: lightning”.Lightning has for long been the bugbear of electrical appliances, the lure of so much sweet, conductive metal in one spot simply too much for heaven’s own electricity to withstand. It’s a siren song as old as time, but the tune is no easier to hum along to. Every year, insurance companies pay out millions in lightning-related claims, and some firms do not compensate for lightning damage as it’s seen as a vis major.“With this in mind,” continues Tony “the design engineers approached the CSIR [Council for Scientific and Industrial Research] and other institutions who had the equipment and knowledge to tame lightning.“A cost-effective and highly efficient circuit was designed that has remained with Centurion Systems to this very day, ensuring that our control cards continue to function when other equipment has failed”.Tony provides a detailed description of the kind of technology that goes into such a sophisticated and robust piece of equipment.“CENTURION uses a layered approachto protect against lightning; all inputs exposed to the outside world are protected by multiple components”.

Layer 1

Right up front is a high-power resistor that absorbs and slows down the lightning surge.This is followed by a Zener (analogous to a clamp) that prevents the lightning-induced voltage from going above levels that are harmful to the rest of the electronic components on the PC board.

Layer 2

The lightning-induced voltage sometimes climbs much faster than the Zener is able to respond; to further protect the sensitive electronic components, another capacitor and resistor are used to slow down the rising voltage allowing the Zener time to respond and clamp the harmful voltages.

Layer 4

To protect against lightning surges, the energy that is being absorbed by the above mentioned layers needs to find a path to earth or ground; to achieve this, another gas arrestor connects to the mains power supply earth.

Layer 5

CENTURION power supplies like the CP84SM have an earth tab that connects to an earth spike, allowing the lightning surge energy to find a very quick and easy path to earth, thereby avoiding damaging the sensitive electronic components on the control card.

Layer 3

The TRG [trigger] input is the one that is most exposed to lightning surges due to it having the longest connection length – this connection could run from the gate motor all the way to the indoor intercom system.To ensure that this input has even more protection against lightning surges, a gas arrestor is placed in front of the high-power resistor to further absorb the energy of the lightning surge.

Layer 6

The power supplies like the CP84SM also have protection against lightning surges coming down the municipal power lines. These take the form of metal oxide varistors, or MOVs. MOVs limit the voltage supplied to an electrical device by either blocking or short-circuiting to ground any unwanted voltages that are above a safe threshold.“Lastly,” Tony concludes “it must be remembered that, if the lightning surge is too powerful or too close to the gate motor then something has to give. That is when most of the components referred to above will be damaged, sometimes leading to unseen damage of other components on the PCB”.In addition to superior lightning protection, CENTURION operators boast a number of sophisticated design features intended to moderate Ma Nature’s onslaughts. These include:

  • Insect-ingress protection – insects are a big problem throughout continental Africa
  • High water-level lines for reasonably good immunity to flooding
  • Black-out and brown-out failure protection – CENTURION’s products are purpose-built to address these classically Third World-type infrastructural problems

Guide to Sliding Gates

to Sliding Gates

Guide to Sliding Gates

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 in the gate automation business composed an ease to follow  Guide to Sliding Gates. 

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 endstopsthat 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.

The Apex Predator of Gate Motors

The Apex Predator of

The Apex predator

CENTURION D5-Evo

It is not often that the worlds of natural science and access automation meet, but I do think that I have, quite by accident, found a parallel.

It was while channel surfing recently, perhaps sub-consciously scouring for material for our next blog post, that I happened upon a show about apex predators, and it got me thinking about our tried, tested and perfected sliding gate motor, the D5-Evo.

Here is something that has been designed to be the absolute best in its class: purpose-built, tenacious and completely unstoppable.

 

So what exactly is an apex predator?

Apex predators have been defined as predators with no natural predators of their own, thus residing at the very top of its food chain. To me, that sums up the D5-Evo perfectly. This superior sliding gate motor exists in a world of many competing operators, each vying for a place at the top of the access automation food chain, each snapping at the ankles of the powerful D5-Evo – the apex predator – but never really finding purchase. The D5-Evoremains the dominant operator.

It’s a bold claim, I know. So let’s take a quick look at why the D5-Evo is the saltwater crocodile (or tiger, or killer whale) of the access automation arena.

 

Lets have a look at the D5’s specs

1. Advanced diagnostics

This feature goes a long way towards establishing our benchmark motor as the undisputed alpha dog in its pack. A futuristic LCD display provides detailed information on everything from the battery and charger voltage to the amount of current being drawn when the gate is in motion to the ID number of the last remote pressed.

2. Intruder-detection Alarm Modes

We’ve written a great deal about this functionality, and with good reason. Enable the Break-in Alarm, and you’ll be notified the moment that someone loiters in front of your gate thanks to the controller’s on board alarm being triggered. Similarly, the Ambush Alarm will notify you should the beams remain interrupted for a pre-defined period of time, so criminals won’t get away with sticking insulation tape over the beam lenses. Remember, you have the apex predator standing guard!

3. Multiple operating features

One characteristic of an apex predator is that it has evolved to adapt remarkably well to its environment. In much the same fashion, we have designed the D5-Evo to be fully configurable to suit any site conditions. From adjustable ramp-up and ramp-down distances, to Positive Close Mode and ultra-safe collision sensitivity, the D5-Evo is the master of its environment.

4. Onboard timer technology

This feature is one of my favourites. Those of you with a working knowledge of ancient Greek will know that the word “chronos” means of or related to time, and it makes a fitting prefix to our built-in, ultra-advanced timer technology known as ChronoGuard. ChronoGuard allows you to set automatic activation for certain times of the day, month or year and even includes a time-barring feature whereby certain inputs can be barred from working after hours, during public holidays, etc. This is absolutely groundbreaking functionality as far as the marriage of access automation and perimeter security goes.

Evolution of the home automation system

Evolution of the
system

Gate automation was born out of necessity.  The public at large were starting to become increasingly more security-conscious as stories of break-ins and house robberies haunted the media, walls grew taller and guard dogs grew larger and more ferocious.  A universal cry was uttered for some technological means of safeguarding ourselves against crime while at the same time relieving us of some of the burdens associated with suburban living. 

The very first gate motors – the great granddaddies of home automation, as it were – were mostly AC-driven behemoths that used limit switches for position control.  Although they undeniably filled a gap and tentatively lulled us into a sense of security, they often proved unreliable as power failures would cause them to stop working (remember, they were powered by the mains) and micro switches frequently failed.

Our very own D5 sliding gate motor – a tried, trusted and beloved stalwart of home automation – not only boasts battery backup and reliable position sensing, but has undergone a complete transformation in recent years.  The CP80 controller has been replaced with an intelligent LCD interface that makes setup and diagnostics exceptionally easy, and space-age features such as Intruder-detection Alarms and on board timer functionality come standard with the aptly-titled D5-Evo.  When it comes to gate automation, this model is evolution at its most visible.

Gate automation has become an integral part of our lives, and we trust in it as much as we do in our loyal guard dogs.  It offers convenience and peace of mind, and we are confident that it will keep evolving to suit our changing needs.
