Therefore it is worth spending a few moments to check over your machine to make sure it is set up and lubricated correctly – a little TLC goes a long way to preventing breakdowns! </p>
<p dir="ltr"> </p>
<p dir="ltr">With this in mind, I have recently finished filming a series of short DIY maintenance movies to show you what to do. The movies cover all essential maintenance and how to fix common problems - you can reach the movies via the YouTube link below. In one of the movies I show you how to lubricate your machine to prevent overloading and in another I show you how to fix irritating squeaks, rattles and vibrations; I think that if your machine sounds and feels right then it follows that it should be running right as well!</p>

<b><u>Treadmills with 2 x Speed Sensors (eg. LiveStrong/Vision)<o:p></o:p></u></b></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<b>Summary<o:p></o:p></b></div>
<div class="MsoNormal">
Some treadmills are fitted with 2 x speed sensors .<o:p></o:p></div>
<div class="MsoNormal">
One is a standard magnetic reed switch fitted near the
roller pulley and the other is an optical sensor mounted at the rear of the
motor. The magnetic sensor is used for general speed measurement whilst the
optical sensor is used for accurate control and safety.<o:p></o:p></div>
<div class="MsoNormal">
Faults with the optical speed sensor are often confused with
MCB problems, and due to the presence of the magnetic reed switch sensor, the
optical speed sensor is frequently overlooked and not tested at all.<o:p></o:p></div>
<div class="MsoNormal">
Problems with the optical sensor can usually be cured simply
by blowing dust/dirt out of the sensor lens as part of a service. <o:p></o:p></div>
<div align="center" class="MsoNormal" style="text-align: center;">
<br /></div>
<div class="MsoNormal">
<b>Symptom of faulty
optical speed sensor<o:p></o:p></b></div>
<div class="MsoNormal">
Motor runs erratically. <o:p></o:p></div>
<div class="MsoNormal">
Running belt speeds up/down and has trouble holding a steady
speed (irrespective of whether there is a person on the machine). <o:p></o:p></div>
<div class="MsoNormal">
Motor cuts out after a while. <o:p></o:p></div>
<div class="MsoNormal">
Motor runs momentarily but then cuts out almost straight
away.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<b>System Operation <o:p></o:p></b></div>
<div class="MsoNormal">
The system uses a magnetic speed sensor to monitor the
running belt speed and allows the console display (kph/mph) to be re-calibrated
accurately between different models. This allows the same electronics to be
shared among multiple treadmills which saves costs.<o:p></o:p></div>
<div class="MsoNormal">
However, the magnetic sensor is relatively slow to respond which
can lead to speed fluctuations (a perceptible lag while the system makes automatic
adjustments to maintain a set speed). This is also why an E1 speed sensor error
usually takes up to 10 seconds to appear. <o:p></o:p></div>
<div class="MsoNormal">
The optical sensor works much faster. It allows the system
to respond very quickly to speed fluctuations so as to provide a very steady
belt speed. Also, it allows the system to detect a problem far sooner than the
magnetic sensor and hence shut down the system rapidly in the event of a
problem. <o:p></o:p></div>
<div class="MsoNormal">
Therefore, by using the two speed sensors, the manufacturer
can share electronics between different models whilst also providing a very
responsive control system. <o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<b>Operation of the
Optical Speed Sensor<o:p></o:p></b></div>
<div class="MsoNormal">
The optical speed sensor is an electronic device consisting
of an in-built LED and sensor. Light passes from the LED lens to a receiver
which is mounted directly opposite. When the light beam is interrupted a signal
is passed to the MCB (the sensor generates an electrical on/off signal to
indicate speed). The light beam is interrupted by use of a castellated round disk
mounted on the rear of the motor which passes between the light beam of the
sensor which blocks or allows light to pass as it rotates.<o:p></o:p></div>
<div class="MsoNormal">
The optical speed sensor itself has no moving parts and is
inherently reliable.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<b>Common Problems and
Fixes:<o:p></o:p></b></div>
<div class="MsoNormal">
<b>Dust on Lens<o:p></o:p></b></div>
<div class="MsoNormal">
By far the most common problem on treadmills is dust and
dirt on the lens or receiver of the LED. This blocks the light beam and causes
the sensor to give an inconsistent output or no output at all. This can be
resolved by <span style="background: yellow; mso-highlight: yellow;">cleaning the
lens with an air blast or removing the dust</span> with a small, clean paint
brush.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<b>Wires &
Connections<o:p></o:p></b></div>
<div class="MsoNormal">
Optical sensors can have 3, 4 or 5 signals wires depending
on the configuration. These small <span style="background: yellow; mso-highlight: yellow;">wires can be trapped or snagged under screws</span> and can easily
become disconnected. Check connection and wire continuity using an multimeter.
Repair and damaged wires or replace device. (Wiring and pinouts vary and cannot
be easily tested using a multimeter without knowing the circuit)<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<b>Physical damage <o:p></o:p></b></div>
<div class="MsoNormal">
Usually a thin metal castellated disk mounted to the motor
shaft is used to interrupt the light beam of the sensor. This disk is prone to
being bent or damage and can rub or scuff the side of the plastic enclosure of
the LED or the circuit board. This can sometimes create <span style="background: yellow; mso-highlight: yellow;">debris which can block the light beam</span> or in
extreme cases cause complete failure of the sensor. Clean the lens and remove
any plastic debris and re-try otherwise replace the device.<o:p></o:p></div>

<b><i><span lang="EN-US" style="font-size: 10.5pt;">If the E1
error code shows immediately </span></i></b><span lang="EN-US" style="font-size: 10.5pt;">it is likely a wiring connection problem. Check the connector at the
back of the display, in the handlebars and at the bottom of the right side
support post. Make sure that the connectors are turned the right way, that none
of the pins are bent and that they are firmly pressed together. If this does
not sole the problem you <st1:personname w:st="on">may</st1:personname> have a
problem with a wiring harness. Check to see if the harness was damaged during
assembly by visibly inspecting the harness where the handlebars and the support
post are connected during assembly and where the support post is inserted into
the base. If there are signs of damage, you can isolate the mid-section of
wiring harness and test to see if this is the problem through removing the
display from the handlebars and attaching it directly to the end of the wiring
harness coming out of the right side of the base. If the display now works
properly, replace the damaged wiring harness.<o:p></o:p></span></div>

<u><b>Problems with DC motor brushes on Treadmills</b></u></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
See photos below for an interesting case study with
regards to DC motors that was found by one of my Engineers.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The motor in the photos had passed our motor current test at 3.9A at 220VAC on load at 12kph, suggesting all was well. However, the machine, a European spec Sprint 9 domestic treadmill, showed an intermittent error 3 which we noticed was triggered when
using one of the console programs functions which had a fast acceleration at
start-up. The problem was not showing when starting the machine slowly on
manual mode.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The issue is that the carbon brushes and commutator have
been arcing/sparking (burning) as shown in the middle picture below. This is caused when there is a small gap between the
face of the carbon brush and the commutator (the copper segmented ring on the
rotor of the motor). In this case, the burnt brush in the motor gets stuck in the slideway
which you can feel when you push the brush in with your finger! The brush does not freely slide in and out of the slideway. This means it
has been prevented from having a good contact with the commutator, which is why it
has been arcing.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
By nature, arcing is transient (very short) bursts of
energy. Because the spark is present for only a very short period of time, the
motor does not show as faulty when measuring the current draw on the current
clamp – the sparks would have to be much bigger and last for a lot longer to
have an effect on the current draw of the motor. This is why it had passed our
motor current test. <o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
However, the spark does create a great deal of electrical
interference which causes the MCB to shut down (intermittently) which is why we
tended to get the error 3 during a rapid acceleration rather than on a slow
start (the arcing would have been more during high acceleration). Our motor test box
has very high immunity to electrical interference and it is not affected by the
arcing which is why it did not cut out under the same circumstances.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
This is a fairly rare fault but worth bearing in mind
especially if you have reports of the motor intermittently cutting out – check
the brushes and commutator for burning, especially if the current readings are good!<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The photos show you what a good brush will look like and
what a bad brush will look like and what a burnt commutator will look like. <o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<br />
<div class="MsoNormal">
On this job, my Engineer changed the motor for a new one which
cured the problem. We decided that it was more cost effective to do this rather than strip down the motor to fix the slideway.</div>

<span style="color: #002060; font-family: "Calibri","sans-serif"; font-size: 11.0pt;">In speaking with my gym manager, our feeling is that our
treadmills will on average be running at 10kph. </span><span style="color: #002060; font-family: "Calibri","sans-serif"; font-size: 11.0pt; mso-fareast-language: EN-US;">Therefore, we chose to measure the current in the loaded and unloaded
condition at 10kph on each of our treadmills. </span><span style="color: #002060; font-family: "Calibri","sans-serif"; font-size: 11.0pt;">For info, I ran on the
machines for the loaded test and I weigh 91kgs. For comparison, we also
measured the current at maximum speed of our Life Fitness T9i treadmill with a new <a href="http://www.northwick.eu/Pages/PowerBelt.aspx" target="_blank">PowerBelt</a> and platform (20pkh).<o:p></o:p></span></div>

<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="color: #002060; font-family: "Calibri","sans-serif"; font-size: 11.0pt;">I conclude that all of our gym treadmills are running at, or
close to, their optimum condition. Therefore, it would be appropriate to set
the Treadmill Saver amber warning set point to be slightly higher than the
optimum so as to avoid false triggers. I would recommend a +20% current
drift from optimum which would make the amber set point about 4A.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="color: #002060; font-family: "Calibri","sans-serif"; font-size: 11.0pt;">For the red set point, it would be desirable to choose a
threshold which is somewhat higher than the amber set point but not so high as
to allow the machine to operate continuously outside of its maximum operating
parameters. Based on the current draw at top speed of the Life Fitness T9i, the
maximum current draw (maximum speed in the loaded condition) is 8.8A. However,
we found that it is not possible to run at 20kph for more than about 5 seconds.
Therefore, it is reasonable to suppose that the design criteria used for
treadmills is actually based around a <u>continuous</u> current (speed) rating
rather than a peak current (speed) rating and so I suggest 6A is a realistic
set point for red.<o:p></o:p></span></div>

<div class="MsoNormal">
<span style="color: #002060; font-family: "Calibri","sans-serif"; font-size: 11.0pt;">Therefore, I would recommend an amber (maintenance overdue) set point of 4A continuous
and a red (stop using) set point of 6A continuous. <o:p></o:p></span></div>

<br />
<span style="font-family: Calibri, sans-serif;"><br /></span>
<span style="font-family: Calibri, sans-serif;">I
have some data regarding the current consumption measurements that I made after fitting a new <a href="http://www.northwick.eu/Pages/PowerBelt.aspx" target="_blank">PowerBelt</a> running belt recently supplied for our Life Fitness T9i
treadmill at my own gym in Worcester.</span><br />
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Calibri, sans-serif;">For
this test, I measured the “before” and “after” amps using a true RMS (AC)
current clamp hooked up to a <a href="http://www.northwick.eu/Pages/treadmillsaver.aspx" target="_blank">Treadmill Saver</a> current loop. The results below
are what I found at a 5kph steady walking pace. <o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Calibri, sans-serif;">For clarity, the terms "unloaded" and "loaded" below simply refer to whether the treadmill was being walked on or not when the measurement was taken.</span><br />
<span style="font-family: Calibri, sans-serif;"><br /></span>
<span style="font-family: Calibri, sans-serif;">Finally, for the true Engineers out there, I weigh 91kgs (200lbs) and the treadmills are all European spec 220V AC 50Hz. </span><span style="font-family: Calibri, sans-serif;"><br /></span>
<span style="font-family: Calibri, sans-serif;">Before
belt & platform change:</span></div>

<div class="MsoNormal">
<span style="font-family: Calibri, sans-serif;">Note
– upon removal, the original belt and platform were found to be in good condition and
plenty of residual silicone oil was in evidence.<o:p></o:p></span></div>

<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Calibri, sans-serif; font-size: 11pt;">It has to be said, that the baseline current measured here in the
“before” condition was very favourable (low) to start with and would not
normally have warranted a new belt or platform being fitted. This reflects the
high standard to which we maintain our <a href="http://wr3.me/" target="_blank">own gym</a> equipment. For comparison, in my
experience, I have measured baseline current draw at 6A to 8A in the “loaded”
condition in facilities where there has been little or no treadmill maintenance. In these situations, a PowerBelt and preventative maintenance routine could <span style="background-color: yellow;">reduce energy consumption by as much as 75%</span> based on these figures.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Calibri, sans-serif; font-size: 11pt;">I can conclude that by using a
new treadmill belt combined with a new platform resulted in a
significant and measurable reduction in current draw. Even under these
rather favourable conditions I was able to measure -0.6A (-23%) less current
after the new <a href="http://www.northwick.eu/Pages/PowerBelt.aspx" target="_blank">PowerBelt</a> and platform had been fitted. <o:p></o:p></span></div>

opinion, reducing the current will also have a long term positive effect
in helping avoid failures of expensive components such as the motor and drive
circuit board; the lower current consumption means these items will run cooler
for longer and will ensure they operate well within their design parameters (so
no stresses to bring about premature failure!).<o:p></o:p></span></div>

<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Calibri, sans-serif; font-size: 11pt;">The current monitoring capabilities of the Treadmill Saver
provides a convenient way to alert the user when belt maintenance is required
and, now that we have optimum conditions here with the new belt and platform
fitted, I will conduct some further work to establish where we should be
setting the trigger points for the amber (maintenance overdue) and red (stop using) warning.<o:p></o:p></span></div>

<span style="font-family: Trebuchet MS, sans-serif; font-size: x-small;">My gym maintenance training course has been very well received and it is specifically aimed at equipping gym owners and staff with the necessary skills to complete a wide range of repairs, servicing and maintenance. I have run the course for private individuals and organisations including The NHS and The Fire Authority. It is a great way to save money on Engineer call outs and to keep on top of problems before they develop into major breakdowns!</span></div>

22:27:15 Life Fitness T5 </span><span style="font-family: 'Trebuchet MS', sans-serif; font-size: 10pt;"> "I bought Life Fitness T5 2nd
hand. Stripped it completely, cleaned and put back together.There was loud
squealing from the motor drive belt so I replaced it.I've done my best but am
no expert so therefore if it is imperative that an expert come and set it up
properly for me, this is something I would consider. There is
slight squeaking at higher speeds when I am running. I used
3 in 1 Professional Silicone Lube on the deck, may be I need use something
else, maybe its another issue altogether

<div class="MsoNormal">
<span style="font-family: 'Trebuchet MS', sans-serif; font-size: 10pt;">Thanks for your enquiry. </span><span style="font-family: 'Trebuchet MS', sans-serif; font-size: 10pt;">This kind of problem could be a slipping drive belt. Sometimes the treadmill drive belt will slip if there is too much friction between the treadmill running belt and the treadmill running platform; this can occur even if the drive belt is correctly tensioned. It may be that you need more lube on the running belt but be careful not to over-lubricate as this can lead to the oil migrating to the drive belt and also cause it to slip! I would recommend pure silicone oil or gel rather than aerosol spray. 3 in 1 silicone contains additives and I prefer not to use it. </span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: 'Trebuchet MS', sans-serif; font-size: 10pt;">If you feel you need a visit then a full
diagnosis of the problem would be a fixed price of £69+VAT. If we can repair your treadmill on the day then we do so and typically these kind of repairs add an
extra £30 to £50+VAT. If you need new parts or the repair looks like it could
get more expensive, we would ask you to pay for the diagnosis charge and then
we would quote you a fixed price for the repair so that you can make the best
decision (you would not pay for another diagnosis if a return visit is
needed!).<o:p></o:p></span></div>

It is slipping badly when in use and it has gradually got worse over the past few months. If I step hard on the belt, it can almost stop!

<div class="MsoNormal">
<span style="color: #003366; font-family: "Trebuchet MS","sans-serif"; font-size: 10pt; mso-fareast-language: EN-GB;">Health and Safety law requires all gym operators to maintain their gym equipment to a safe standard. An easy way to ensure you comply with this legislation is to have your kit inspected and maintained periodically by a gym repair specialist. <o:p></o:p></span></div>
<div class="MsoNormal">
<span style="color: #003366; font-family: "Trebuchet MS","sans-serif"; font-size: 10pt; mso-fareast-language: EN-GB;"><o:p> </o:p></span></div>
<div class="MsoNormal">
<span style="color: #003366; font-family: "Trebuchet MS","sans-serif"; font-size: 10pt; mso-fareast-language: EN-GB;">But how do you know that the person issuing your inspection certificate is qualified to do so? In other words, if it came to it the crunch and you needed to demonstrate in a court of law <span style="height: 140px; margin-left: 14px; margin-top: 274px; mso-ignore: vglayout; position: absolute; width: 270px; z-index: 251659264;"></span>that you have had your equipment adequately maintained, would your gym inspection certificate be worth anymore than the paper it is written on?<o:p></o:p></span></div>
<div class="MsoNormal">
<span style="color: #003366; font-family: "Trebuchet MS","sans-serif"; font-size: 10pt; mso-fareast-language: EN-GB;"><o:p> </o:p></span></div>
<div class="MsoNormal">
<span style="color: #003366; font-family: "Trebuchet MS","sans-serif"; font-size: 10pt; mso-fareast-language: EN-GB;">In the UK, the fitness repair industry is largely unregulated. There are trade organisation such as UK Active who provide a useful point of reference but so far as implementation of standards and safe working practices goes, there is nothing. There are the original equipment manufacturer’s (OEM’s) who design and build equipment and the more well-know manufacturers would be deemed to have sufficient expertise when it comes to underwriting your gym inspection certificate. However, many gyms contain a mixture of equipment from multiple manufacturers and it’s just not practical to obtain an inspection certificate from every manufacturer to cover your whole gym!<o:p></o:p></span></div>
<div class="MsoNormal">
<span style="color: #003366; font-family: "Trebuchet MS","sans-serif"; font-size: 10pt; mso-fareast-language: EN-GB;"><o:p> </o:p></span></div>
<div class="MsoNormal">
<span style="color: #003366; font-family: "Trebuchet MS","sans-serif"; font-size: 10pt; mso-fareast-language: EN-GB;">This is where independent repair specialists can provide a solution. These people are used to dealing with all kinds of equipment; any age, any condition, any make and any model. They can have good detailed knowledge of mechanical and electrical/electronic systems and will be familiar with a range of different potential failure modes. So far so good! The problem is that anyone with a van and a toolbox can adopt the title of “Technician” or “Engineer” when in fact, they may be better qualified as a Butcher, Baker or Candlestickmaker! <o:p></o:p></span></div>
<div class="MsoNormal">
<span style="color: #003366; font-family: "Trebuchet MS","sans-serif"; font-size: 10pt; mso-fareast-language: EN-GB;"><o:p> </o:p></span></div>
<div class="MsoNormal">
<span style="color: #003366; font-family: "Trebuchet MS","sans-serif"; font-size: 10pt; mso-fareast-language: EN-GB;">Fortunately, there is a way to navigate through such nomenclatures. <o:p></o:p></span></div>
<div class="MsoNormal">
<span style="color: #003366; font-family: "Trebuchet MS","sans-serif"; font-size: 10pt; mso-fareast-language: EN-GB;"><o:p> </o:p></span></div>
<div class="MsoNormal">
<span style="color: #003366; font-family: "Trebuchet MS","sans-serif"; font-size: 10pt; mso-fareast-language: EN-GB;">For example if your gym repair specialist a sole trader, you could ask for his/her credentials. You would expect that they would have some kind of Engineering or technical background, apprenticeship indentures or Higher National Diploma for example, perhaps relevant experience in the repair service sector or a track record in with a manufacturing organisation. They should also be able to provide you with at least a couple of references that you can check out to help validate their claimed expertise.<o:p></o:p></span></div>
<div class="MsoNormal">
<span style="color: #003366; font-family: "Trebuchet MS","sans-serif"; font-size: 10pt; mso-fareast-language: EN-GB;"><o:p> </o:p></span></div>
<div class="MsoNormal">
<span style="color: #003366; font-family: "Trebuchet MS","sans-serif"; font-size: 10pt; mso-fareast-language: EN-GB;">If you are dealing with a Company then you can also enquire about their recruitment and training policy; how do they select and train their “Engineers”? A quick bit of internet research may also reveal details about who owns the Company, their client base and reveal some real-life customer reviews. You can also look to see if they are members of any relevant trade organisation. In the UK you can contact “The Fit Group” and “UK Active” both of whom have approved supplier databases.<o:p></o:p></span></div>
<div class="MsoNormal">
<span style="color: #003366; font-family: "Trebuchet MS","sans-serif"; font-size: 10pt; mso-fareast-language: EN-GB;"><o:p> </o:p></span></div>
<div class="MsoNormal">
<span style="color: #003366; font-family: "Trebuchet MS","sans-serif"; font-size: 10pt; mso-fareast-language: EN-GB;">Ultimately, you should look closely at the signature on your gym inspection certificate and ask yourself whether that person is (a) qualified to be signing the document and (b) has the relevant authority to do so. As a guide, I would suggest that the person signing your certificate should be a professional Engineer (such as a “Chartered Engineer”, “Incorporated Engineer” or “Engineering Technician”) and a member of a nationally recognised Engineering organisation such as The Engineering Council, The IET or The IMechE and that they are currently holding a senior position within in their organisation such as Owner, Director, Partner or Quality Manager.<o:p></o:p></span></div>

<div class="MsoNormal">
<span style="color: #003366; font-family: "Trebuchet MS","sans-serif"; font-size: 10pt; mso-fareast-language: EN-GB;">Anything less should ring alarm bells!<o:p></o:p></span></div>
