Congratulations on your new Ergometer!

Monark 939 novo is designed to perform stress tests when connected to an ECG device. When connected to a PC or terminal, the bike can be used to perform Max and SubMax cardiovascular tests, calculate VO

capacity and more. The bike can also be used for normal exercise.

Each 939 novo is calibrated at the factory. This means that you can begin to use the ergometer directly after assembly. But as usual when the bike has been moved, an electronic calibration must be done, see instruction for “Calibration” in this manual.

Initial operation

Each 939 novo is mechanically calibrated at the factory. The user can always verify this by performing the mechanical calibration of the pendulum. See section ”Mechanical calibration”.

Connect power to the bike by ﬁrst connecting the cable from the power adaptor to the bike into the power connector (2) in the front of the bike, see Fig: Connections. Then plug the power adaptor into the wall outlet. Turn on the power switch (4) and a green LED lights up.

Perform the electrical calibration as speciﬁed in section "Calibration electronics”. Test by pedalling the bike. If the bike is working properly, it is ready for use.

Fig: Adjustments

1) Locking knob, saddle

2) Locking handle, handlebar

Cycle adjustments

The seat height should be adjusted to a comfortable position. The appropriate height is when you have the knee slightly bent when the sole of the foot is centred over the pedal axle with the pedal in the bottom position. When adjusting the saddle height, do not sit on the saddle, stand next to the bike. Loosen the locking knob (1) on the seat post by rotating it about one turn counterclockwise and pull it out. Adjust the seat height, and when you have found the right height it is important that you tighten the locking knob securely (clockwise until it stops). See Fig:

Adjustments.

The handlebar setting should be in a comfortable position when cycling. During longer exercise sessions it is recommended to occasionally change handlebar position. To adjust the handlebar, loosen the quick release lever (2). See Fig: Adjustments.

Power on crank or ywheel

Monark bikes measure the effect of the ﬂywheel, so it will be a friction of 6-8% if you measure the impact of the pedals (if the effect is measured on the crankshaft, the difference is 4-5 %). The losses will be primarily due to friction in the chain, pedals and bearings in the wheels and crank.

939 novo is designed for ﬁtness tests and are set to measure the power at the ﬂywheel, which is the traditional way in submaximal exercise. The bike can be set to work with effect in the pedals / crankshaft (the cycle constant).

Here are instructions for connection and options for connection to external devices. If advanced technical documentation / data protocol for system builders or similar are required, please contact Monark Exercise AB.

Operating instruction

How the bike works

939 novo is built on a stable frame, a large wellbalanced ﬂywheel, a break belt and a pendulum weight which measures the force. The pedals operate around the ﬂywheel via a chain, while a stretch mechanism tightens the brake belt to regulate the braking force to affect the ﬂywheel. This braking force can be read directly by the pendulum on the scale on the left side of the bike.

All changes in the friction between the brake belt and the ﬂywheel are compensated automatically by Monark's unique construction.

New on 939 novo is that you can control the bike from the display but the bike can, as earlier models, even be controlled externally from PC or other equipment. The display functions are described in section "Monark novo display unit". The computer system consists of Monark novo control unit (built in the bike) and Monark novo display unit, PC or other external equipment. Monark novo control unit registers pedal speed and braking force, and also registers the test person's heart rate if a chest belt or similar is used. Monark novo control unit activates an actuator that adjusts the brake belt tension, which regulates the work load. This work load is varied automatically in relation to changes in pedal speed, so that a constant power is maintained. The bike is standard rpm independent but can be set to also be rpm dependent (constant force).

The control is performed over a serial line using ANSI/ISO/ASCII format commands. The connector is a 9-stick D-sub (male).

For information about how respective control units work, see section "Connection to external control unit".

Pulse measurement

The person's heart rate ("pulse") can be measured by a chest belt or similar heart rate monitor that register the pulse signal from your heart and sends it to the bike with ANT+ or Bluetooth SMART technology. More information is available in section "Monark novo display unit".

The heart rate can be displayed in Monark novo display unit, in Monark test software or in other external equipment.

If you use chest belt

Heart rate monitoring requires that the chest belt is correctly placed. When it is correctly ﬁtted the logo on the belt will be central and readable, outward and upright, by another person. Before putting on the belt, clean the skin where the belt is to be placed. The chest belt should be secured at a comfortable tension around the mid section, just below the breast muscle, see Fig: Placement chest belt. Moisten the electrodes before use, see Fig: Moistening the electrodes.

The images above are used with permission of Polar Sweden.

Fig: Placement of the chest belt

Fig: Fig: Moistening the electrodes (1)

Page 9

939 novo

Checking the pulse function

The heart rate can be displayed in Monark novo display unit, in Monark test software or in other external equipment.

While the patient rests, with the heart rate monitor on, compare the displayed heart rate (Monark novo display unit, PC or other) with the manually taken pulse. If it does not correspond, check the chest belt contact area and if necessary moisten the electrode surfaces with water.

The following points should also be checked to ensure the bike's function:

Check the adjustment / zero of the scale• Check the pulse function• Check the braking force• Test by pedalling and check that a reasonable rpm •

is obtained - verify by a clock. Feel if the pedals move smoothly. Listen for unusual sounds. Adjust if necessary.

Adjust the handlebar and saddle and make sure • they are securely attached and that the adjustment is working properly.

Make sure the support legs are in position by • rocking the bike. Tighten if necessary.

If something unusual is found during the daily inspection that you cannot resolve, please call customer service.

Daily check

Validation of force

Start Monark test software in your PC (the software is available for free download from our web site: www.monarkexercise.se) and select a test programme from the menu "Test". In the dialogue box that opens is a box showing the braking force in Newton, see Fig: Force and HR display. You do not have to press "Start" (1) to get the heart rate showed (2), but you must press "Start" to show the force (3).

With the pendulum pointer at 0, the display should 1. read "00N".

Move the pendulum pointer to 4 kp and the display 2. should show "39N".

If the braking force is not displayed correctly, an calibration of the pendulum must be done. See section "Calibration".

NOTE! After this veriﬁcation, the brake belt will be loose. This means that it will take some seconds before the regulating device has tensed the brake belt to normal again after you have started pedalling. If it then heavy to pedal, add force on the pedals and the bike will decrease the workload until it is possible to pedal around.

Fig: Force and HR display

1) Start

2) Heart rate display

3) Force in software (manual test)

The following procedure will assure the user that the ergometer is performing properly on a daily basis. The control includes test of the mechanical braking, pedalling and speed systems as well as computer control and sensing capability of the mechanical system. Additionally, if a calibrated ECG simulator is available, it may be used to verify the heart rate measuring system. Whether the simulator is used or not, the heart rate system may be validated by simply taking a pulse point rate measurement at the neck for example. While a patient is at rest and has been prepared for chest belt or other heart rate monitor, the pulse indicator ﬂashes once per pulse beat. The ﬂashing heart rate must be consistent with the manually recorded pulse. If it does not correspond, check the chest belt contact area and moisten if necessary the electrode surfaces with water. If this fails, please call customer service.

Connection to external control unit

No tests can be performed at Monark novo display unit, then you must connect your bike to a PC, via the Monark novo control unit, and use a special test software. A suitable one is available to download from our website: www.monarkexercise.se.

The bike do not need to be switched off when connecting external components, but it is recommended, to prevent transmission of incorrect data.

Be careful when connecting different types of external devices to prevent ﬂash-over and subsequent injury. The user must ensure that the correct cables are used, otherwise you risk serious injury or equipment damage.

Connect external device via RS232

Make sure the power adaptor is connected to the bike. Turn off the power switch on the bike.

Connect the RS232 cable to the port on the bike, see Fig: Connections. Connect the other end of the RS232 cable to the external device. Set the bike power switch to "on" and then start the external device.

Connect external device via USB

Make sure the power adaptor is connected to the bike. Turn off the power switch on the bike.

Connect the USB-B cable to the port on the bike, see Fig: Connections. Connect the other end of the cable to the external device. Set the bike power switch to "on" and then start the external device.

By using a USB A-B cable, you can connect external devices that only have USB-A connections to this port.

Communication protocol (command type)

The bike's two free ports can be set in various command types to suit different standards and external equipments. The four available command types are:

0: Standard command set or ”PC-mode”

Command type "0" is default for both of the free ports. As default the baud is 4800, but can be changed by external control. The protocol is used by Monark Exercise software and some external controllers that are prepared to fully beneﬁt from the advanced capabilities of the bike.

2: Ergoline compatible (recommended for ”er900”)

This command type is used when the bike is controlled by an external device that uses Ergoline's "er900" protocol, baud rate is locked to 4800. If the external device "asks" the bike about current power, the bike responds with the set power. This setting is recommended before the command type 3 which removes the risk of the device trying to "chase" a value.

3: Ergoline compatible (alternative)

4: 839 compatible

This command type is very similar to command type "0", the only difference is that if an external device requests the ID, the bike responds as if it was an 839bike of newer model. The setting is used for older external control units that are not yet adapted to Monark novo series ("backwards compatible").

All commands for external devices are active regardless of the command type that is selected in addition to the small differences presented above. The parts in Ergoline protocol that handle blood pressure and its parameters are not implemented.

The two free ports can have different settings.

When connecting to multiple devices, it is important to ensure that one device does not sets a new target without the other devices note it (master - slave).

NOTE! The bike can not be controlled by the handheld controller (Art. No.: 9339-51) used on previous models.

Page 12

939 novo

Command type settings

Default for the two free ports is command type 0, which will work in most cases. If you need to change you can do it in settings in terminal mode in the Monark Exercise software.

Ensure that you are connected to the bike. Type ping in the command line in the window. Then the bike beep once and answer pong in the text window above the command line, see Fig: Terminal window.

You can set the command type for both ports regardless of which port the bike is connected to.

Fig: Terminal window

Command line

Bike answer

Use the following commands:

cmdtypers232 #• and press ENTER to set the RS232 port to the command type #, where # is 0, 2, 3 or 4

cmdtypeusb #• and press ENTER to set the USB port to the command type #, where # is 0, 2, 3 or 4

If you only send the command cmdtypers232 alternatively cmdtypeusb without digit, the bike responds with the current command type (0, 2, 3 or

4) for the connection. When power is turned on to the bike it gives an

indication of what command type the RS232 port is set to. First, a long beep followed by the same number of short beeps is the command type settings for the RS232 port. In default ("0") you do not hear a short beep, but at normal Ergoline setting ("2"), you hear two short beeps after the long beep.

0 — A long beep 2 — A long beep followed by two short beeps 3 — A long beep followed by three short beeps 4 — A long beep followed by four short beeps

Via the display, you can perform manual training with full precision and performance!

With Monark novo display unit, you can control the bike via the touch screen. The display shows the current rpm, time, power and pulse (if any heart rate monitor is used).

You can also set up target based training regarding distance, time and calories. If you want to do ﬁtness tests, etc., you can download Monark test software to your PC from our website, www.monarkexercise.se, and then connect your PC to Monark novo control unit on your bike.

Start training

The display will start automatically after you have turned on the power to the bike.

Then the display shows the Start view. Now if you want to start, press the "Start" button, the display will show normal mode and the time starts counting.

If autostart is enabled, the time starts count ten seconds after you have started to pedalling, without you have to press "Start". Autostart is set in "Settings general".

This is "Normal mode" that can be displayed in two versions, complete and simple. You can switch between them by pressing the arrow keys (change screen) in the middle of the short sides on the display.

Calculation l / min:

Monark novo display unit uses a formula (cubic equation)to calculate VO

at different workloads. The result is according to Astrand's table between 150 W and 300 W, and a good approximation for 15700 W and a cadence of about 50-65 rpm.

These values should only be regarded as an indication to meet Åstrand, for further details see the current literature!

Pulse settings

Here you can choose what heart rate standard you want the bike to search for, Bluetooth SMART, ANT+ or both.

Current heart rate

Lock to bluetooth

Lock up bluetooth

Home

ANT+

(ANT+ is always active) ANT+ uses "proximity pairing" which means that

you should be close to the display for it to start listening to it. When the display and the heart rate monitor is paired, you can be relatively far from the bike with retained function. This process ensures that the display is listening on the correct belt.

If you have connected to an ANT+ heart rate monitor it says "connected" at "ANT+ status:" and the current heart rate is displayed at "Pulse".

The person's heart rate ("pulse") can be measured by, for example, a chest belt that detects your pulse from your heart and sends the pulse to the bike with Bluetooth SMART or ANT+ technology.

Fig: Placement chest belt

Fig: Moistening the electrodes

Bluetooth SMART

When the bike and a Bluetooth SMART heart rate monitor have been paired the heart rate monitor Bluetooth ID and the current heart rate is displayed at "Pulse". You can choose to actively lock the heart rate monitor by pressing "Lock". Then the bike is only searching for that particular heart rate monitor. Press "Reset" if you want to release the lock to only a speciﬁc heart rate monitor and lock with a new or continue to search freely.

You can use several Bluetooth SMART heart rate monitors to the bike, but you can only lock to one at a time.

The bike locks to the heart rate monitor that it ﬁnds ﬁrst (within 10 m). If more heart rate monitors are used, we therefore recommended to lock into a speciﬁc Bluetooth ID to ensure that the correct heart rate appears.

NOTE! (for Bluetooth SMART) It must be ensured that no other belts in addition to the belt that should be paired to the bike is active OR that any other device (cell phone, bike computer, etc.) that could connect to the belts are active during the process!

If you use chest belt

Heart rate registration requires that the heart rate monitor is positioned correctly. When it is correctly ﬁtted the logo on the belt will be central and readable, outward and upright, by another person. Before putting on the belt, clean the skin where the belt is to be placed. The chest belt should be secured at a comfortable tension around the mid section, just below the breast muscle, see Fig: Placement chest belt. Moisten the electrodes before use, see Fig: Moistening

The bike has a module that can connect to the Bluetooth SMART compatible heart rate belts or similar equipment designed to this standard. The standard includes no distance function so we recommend different procedures depending on whether there is only one heart rate monitor or there may be several within the range of the receiver (10-15 m).

Connection to heart rate monitor with solitary bike (pulse mode 2) STANDARD

This works when you only have one bike with Bluetooth SMART and other monitors with this standard within the receiver range, normally 1015 m.

The bike is set by default to automatically connect temporarily with the ﬁrst active heart rate monitor with Bluetooth SMART technology that comes within the range. The bike is paired with this monitor until the signal is dropped. Heart rate monitors tend to stop transmitting within 30 seconds to two minutes from the time they lose pulse contact or have been taken off. As soon as a signal is dropped, the bike begins to search for another heart rate monitor (new or old).

You can use several heart rate monitors on the same bike but it may only activate one monitor at a time (within range).

Connection to heart rate monitor with several bikes (pulse mode 3)

In a room with several bikes or other equipments that also use Bluetooth SMART heart rate monitors, every bike should be locked to a speciﬁc heart rate monitor so you have control of which is connected to which bike.

This can be done in Monark novo display unit or in Monark test software or similar.

Open the terminal window. Ensure that you are connected to the bike. Type ping in the command line in the window and press Enter. Then the bike beep once and answer pong in the text window above the command line, see Fig: Terminal window.

NOTE! Electromagnetic waves can interfere with pulse function when wireless chest belt or similar is used. Cellular phones or similar are not allowed to be used near the bike during test.

In case of problems, turn off WiFi, Bluetooth and similar on computers nearby.

NOTE!

It must be ensured that no other belts in addition to

the belt that should be paired to the bike is active OR

that any other device (cell phone, bike computer, etc.)

that could connect to the belts are active during the

process!

Activate the belt by someone wearing it as instructed

and standing near the bike. Type pulsemode 2 in the

terminal window to ensure that the bluetooth system

is active. Then let the the bike pair automatically with

the heart rate monitor. Write regularly pulseble in the

terminal window until the bike responds with the

current pulse value, which means that the bike and

heart rate monitor have been paired. Type pulseble

lock to lock to the active heart rate monitor. With this

the bike is locked only locked against this heart rate

monitor and will ignore all others that may be within

reach. Type pulsebleid in the terminal window and

the bike will respond with the heart rate monitor's

complete id. Note this on the heart rate monitor

along with what bike the monitor / transmitter unit

is locked to for later reference. To check the id that

is locked to the bike, type pulsebleid in the terminal

window and the bike responds.

Alternatively, if you already know the belt's complete

id, you can direct lock it. The complete ID has

the format ##: ##: ##: ##: ##: ##. Sometimes the

equipment ID is printed on the transmitter housing or

packaging but different types of abbreviated notation

appear on, for example Polar belts. There are many

free applications for BLE SMART HR which can be

used to see the heart rate monitor ID in acell phone

or a PC tablet. Then you can lock directly to the heart

rate monitor without having it active by typing the

command pulsebleid "##: ##: ##: ##: ##: ##" in the

terminal window and this will register and lock to

the speciﬁed id (note that it should be " " around the

id).

If you want to return to automatically pair with the ﬁrst compatible heart rate monitor within reach, type the command pulseble break or pulsemode 2

There is a risk that the "dedicated" heart rate monitor may pair with an other device before it is paired to the bike if the other device is within range (cell phone, etc.). Therefore, we recommend that, if possible, all devices with Bluetooth SMART are locked to speciﬁc monitors so that this does not happen. If a heart rate monitor has paired with the wrong device, turn it off and let it lie for a while so it shuts itself down. The time depends on the brand, but it usually varies between 30 seconds and 2 minutes. Then the heart rate monitor is reset. A heart rate monitor can only pair with one device at a time and it is often enough just to reach the electrodes to make it active.

In environments where you want to change test persons without wash and dry the textile belt ﬁrst, you can use so-called textile belts where the transmitter unit sits with quick couplers on a textile belt with electrodes. Then you can use several textile belts but only a transmitter unit per bike and change into dry belts quickly by moving the transmitter unit which is locked to the bike. The transmitter unit is often easy to wipe clean. In this way you can maintain good hygiene when the tests are close together.

Monark Exercise AB has tested several belts, both of famous brands and so-called "no-name". As long as they follow the Bluetooth SMART standard they work on the bike, but we strongly recommend that you use well-known brands such as Polar, because "no-name" belts in many cases have been shown to have both very poor function and range.

Usually it is not necessary to recalibrate the cycle electronically, but it should be done after each service, change of electronic part, movement or if you adjusted the 0-index.

The calibration coefﬁcient calculated by the computer is stored in main memory. No matter when the power is turned on, the last stored calibration will be placed in main memory. New calibration automatically replaces the old.

Calibration is necessary so that the electronic and the mechanical parts of the cycle conform. The work carried out on the bike is a result of the braking force (pendulum mode) and the number of pedal revolutions (= distance). The effect is then counted out by dividing the work done by the time it took to accomplish it. Validation includes both mechanical and electronic procedures.

Calibration

NOTE! The ﬂywheel must be completely stopped before the weight is hung on!

Mechanical calibration

Although all Ergometers are calibrated at the factory the user may wish to verify this by performing a mechanical scale calibration. If so, please do the following:

At ﬁrst, follow the instructions in section • "Adjustment / reset scale". Adjust the pendulum if necessary.

Loosen the calibration hook from the hook holder, • see Fig: Calibration mode.

A checked and approved weight (4), 4 kg (Art. • No: 9000-211), attached to the calibration hook (5), see Fig: Calibration.

At the correct setting the weight has to be read by • the pendulum scale at 4 kp-line (6). (Pendulum pointer should be centered over 4 kg mark.)

Lift off the calibration weight and replace the • calibration hook in the hook holder, see Fig: Normal mode. NOTE! The hook must be left in the holder during use.

If the pendulum pointer does not stand in the middle of the 4 kp mark the pendulum weigh must be adjusted by means of the adjusting weight (2). To be able to do this the left cover must be removed.

To adjust the position of the adjustment weight, the locking screw, in the center of the pendulum (3), must be loosened.

If the pointer shows too low, the adjustment weight must be moved upwards. If the pointer shows too high, the adjustment weight must be moved down and then locked in its new position. This process is repeated until pointer is in the correct position.

Check the calibration of the pendulum once a year or when needed.

Calibration electronics - with the pendulum

The best way to calibrate electronically is with the

pendulum directly at start up. It is also possible to

calibrate the electronics via terminal mode in Monark

test software.

The following steps show how the electronics are

calibrated against the pendulum.

First you need to release the brake belt tension. 1. Move the pendulum to 4 kp and hold it there a while to loosen it. Move the pendulum to zero position again.

Adjust the scale, see "Adjustment / reset scale", 2. so that the pendulum pointer is pointing at the 0-index of the scale, see Fig: Zero position.

Turn off the power to the bike and move the 3. pendulum pointer to 6 kp.

Hold the pendulum pointer at 6 kp and turn the 4. power on the bike again and wait for a beep. Keep left the pendulum at 6 kp and after about 5 seconds you will hear 10 rapid beeps. Move the pendulum to 0 again. Wait for a beep.

Move the pendulum to 2 kp. Wait for a beep. 5. Move the pendulum to 4 kp. Wait for a beep. 6. Move the pendulum to 6 kp. Wait for a beep. 7.

Move the pendulum to 0 again.

The value at each point is stored at the end of

each beep. New value is checked against a table of

acceptable range. If there are any values outside the

acceptance window you will hear three short beeps

directly in connection with each calibration point

and the calibration will not be used (the last previous

stays).

Calibration is complete if no error messages or beeps

are received.

NOTE! The pendulum must be kept still at the different positions. It is also important to keep left the pendulum at each point until the beep stops beeping before moving to the next position.

Fig: Zero position (1)

Fig: Scale adjustment

Adjustment / reset scale

Connect power to the bike. Loosen possible tension in the brake belt by moving the pendulum to 4 kp. Hold it there until the belt feels loose. Then move the indicator to 0 again. Now check if the indicator is aligned with the 0-index on the scale.

If adjustment is needed, loosen the locknut (1) and then change the position of the scale board, so that it will have its 0-index in line with the indicator/moving pointer. Tighten the locknut after the adjustment, see

Fig: Scale adjustments.

NOTE! It is important that you are very precise when you adjust or reset the scale.

Testing with 939 novo

Test person enforcement

The bike performs automated tests virtually by itself, requiring minimal intervention by the test operator. This allows the operator to pay careful attention to the test person without distraction. The response to the exercise protocol can be accurately estimated and appropriate action taken to assist the test person, if necessary. Some programmes have sections where the test person may develop signiﬁcant physical effort. The effect on the test person can not be underestimated.

During the test it is important to observe the test person's appearance and heart rate. The testing should be stopped immediately if the test person reports chest pain, difﬁculty in breathing, etc. A system of prompt medical attention should be set up prior to testing, in case of emergency.

The test person may also have difﬁculty in keeping a steady pedalling speed. This is of minor importance, except in cases where the program assumes a constant braking force, since the effect is automatically adjusted to the correct value as long as the pedal speed is at least 30 rpm. However, it is important to consider what each test documentation says about the pedal speed.

Fig: Placement chest belt

Fig: Moistening the electrodes

The images above are used with permission of Polar Sweden.

The versatility of the 939 novo enable it to be utilized in a variety of testing environments. The precision and reproducibility of the test values obtained with the bike, along with the uncomplicated way to set up the tests, means the bike can be used in clinical work tests, in occupational health services for the ﬁtness tests as well as ﬁtness centers, schools, sports clubs and the like. The backgrounds of both the individuals being tested and those administering the test may be vastly different in these widely varying testing situations.

In general, one should bear in mind that, whether in a clinical test or a simple ﬁtness test in exercise context, the strain on the tested person become quite large. As a precaution, it may be advisable, prior to beginning an exercise protocol, that each test person consults with a physician.

Before testing, the operator should review the entire protocol operation with the test person, explaining the work which will be required and the duration of the procedure. One should also agree on how the test person shall give signs of any fatigue, chest pain or other abnormal physical reactions.

The test person should not engage in heavy physical activity for several hours prior to testing to establish maximum oxygen consumption. In addition, all testing and exercise protocols should be performed a reasonable time after meals. The test person should refrain from smoking within an hour of the testing period.

The test subject should be prepared for riding the ergometer, including the selection of proper clothing which neither interferes with the physical activity nor endangers the health of the test person. Instructions regarding cycling is rarely needed but it may be appropriate that the test leader gives some advice on pedalling, saddle height and adjustment of the handlebar - it should be comfortable to ride. The appropriate height of the saddle is when the knee is slightly bent when the sole of the foot is centred over the pedal axle with the pedal in the bottom position.

Explain how the metronome shows "over-", respectively. "sub-" rpm relative to the set value.

Allow the test person to pedal at a low work load to experience how it feels to hold a steady rpm.

Finally, the chest belt shall be put on, see Fig: Placement chest belt for proper placement. Check for a minute that a proper heart rate is displayed. If you know the test person's normal heart rate you may also determine how nervous he / she is prior to the test. It may be appropriate to let the test person rest long enough before the test so a more or less stable resting heart rate can be read.

Page 27

939 novo

Power calculation

1 rpm = a point on the ﬂywheel moves 6 meters per minute

50 rpm = 300 meters / minute 2 kp force makes 2 x 300 = 600 kpm / min

100 rpm = 600 meter / minute 1 kp force makes 1 x 600 = 600 kpm / min

Exact calculation: Watts = rpm x kp x 0.98065

"Rule of thumb" calculation: Watts = rpm x kp (2% error, but may be good enough in many cases)

Reviewing results

The maximum oxygen uptake is a standard measure

of the condition of the heart- and lung-functions.

Dependent on the linear relationship between work

and oxygen uptake and between work and heart rate,

the heart rate response to work may be used to estimate

the oxygen consumption. If the maximum heart rate

is considered, the maximum oxygen consumption

may be determined.

WHO-, YMCA- and Åstrand protocols estimate

the maximum oxygen consumption, based on a

submaximal workload while all others report the

oxygen consumption required by the ﬁnal workload.

The estimated maximum oxygen consumption

derived from some of the ergometer tests is subject

to the error of the “age related predicted maximum

heart rate“. Although there is a deﬁnite and linear

relationship between work and oxygen uptake, there

are some differences in actual oxygen uptake based

on individual work efﬁciency. Test persons who are

less familiar with bike exercise and those individuals

who are less ﬁt, are more likely be less efﬁcient than

those who ride bikes frequently.

It should be noted that these results are estimates or

predictions of maximal response and have a greater

chance of being in error than if the individual were

tested to their actual maximum value. Interpretation

should therefore be made more carefully with an

understanding of the possibility of errors in the

methodology.

Operation interferences

It is normally considered that about 70 % of all shutdowns on small computers are caused by mains interferences, i.e. at short over voltage. These interferences can often be caused by different machinery, which is started or stopped. The processor in the computer is then reacting incorrectly or is not working at all. The problems can be solved by means of a mains interference protector, which is connected between the wall outlet and the AC adaptor.

Service check and Maintenance

It is important to carry out a regular service on your ergometer, to ensure it is kept in good condition.

Service action:

We recommend isopropyl alcohol to disinfect the • surface of the bike. Use a damp but not wet cloth to clean the surface you wish to disinfect.

Always keep the bike clean and well lubricated • (once a week).

Periodically wipe the surface with a rust preventative, • especially when it has been cleaned and the surface is dry. This is done to protect the chrome and zinc parts as well as the painted parts (4 times per year).

Check now and then that both pedals are ﬁrmly • tightened. If not the threading in the pedal arms will be damaged. Also check that pedal arms are ﬁrmly tightened on the crank axle, tighten if necessary. When the Ergometer is new it is important to tighten the pedals after 5 hours of pedalling (4 times per year).

Check that the pedal crank is secure to the crank • axle (4 times per year).

Be sure that the pedals are moving smoothly, and • that the pedal axle is clear of dirt and ﬁbres (4 times per year).

When cleaning and lubricating be sure to check that • all screws and nuts are properly tightened (twice a year).

Check that the chain is snug and there is no play in • the pedal crank (twice a year).

Check that pedals, chain and freewheel sprocket are • lubricated (twice a year).

Be sure that the brake belt does not show signiﬁcant • signs of wear (twice a year).

Check that the handlebars and seat adjustment • screws are lubricated (2 times per year).

Be sure that all moving parts, crank and ﬂywheel • are working normally and that no abnormal play or sound exists. Play in bearings causes fast wearing and with that follows a highly reduced lifetime.

Check that the ﬂywheel is placed in the center and • with plane rotation.

Service

Note!

Make sure the voltage indicated on the appliance corresponds to the local mains voltage before making connections.

Note that the text about service and maintenance is universal and that all parts may not be relevant to your bike.

Batteries

If the display is battery-operated, the batteries are in a separate package at delivery. If the storing time has been long the battery power can be too low to make the computer act correctly. Batteries must then be changed.

Flywheel bearing

The ﬂywheel bearing is long-term greased and requires no supplementary lubrication. If a problem arises, please contact your Monark dealer.

Crank bearing

The crank bearing is greased and normally requires no supplementary lubrication. If a problem arises, please contact your Monark dealer.

Transportation

During transport the brake cord should be tightened to prevent it from falling off the ﬂywheel.

Replacement of brake belt

To replace the brake belt remove covers if necessary. Make sure that the belt is loose.

To loosen the brake belt on pendulum bikes with engine, connect power to the unit and raise the pendulum to 4 kp. Hold it there until brake belt is loose. Please note how the belt is assembled. Remove it from the bike. Attach the new brake belt and assemble the bike in reverse order.

NOTE! When replacing the brake belt it is recommended to clean the brake surface. See ”Brake belt contact surface”.

Brake belt contact surface

Deposits of dirt on the brake belt and on the contact surface may cause the unit to operate unevenly and will also wear down the brake belt. The contact surface of the ﬂywheel should be smoothed with ﬁne sandpaper and any dust removed with a clean dry cloth.

Remove any potential covers and all workload on the brake belt and then remove it. Grind with a ﬁne sand paper. Grinding is easier to perform if a second individual cautiously and carefully pedals the cycle.

Irregularities on the brake belt contact surface are removed by means of a ﬁne sand paper or an abrasive cloth. Otherwise unnecessary wear on the brake belt may occur and the unit can become noisy.

Always keep the brake belt contact surface clean and dry. No lubricant should be used. We recommend replacing the brake belt when cleaning the contact surface. In regard to assembly and adjustment of the brake belt, see ”Replacement of brake belt”.

Chain 1/2“ x 1/8“

Check the lubrication and tension of the chain at regular intervals. In the middle of its free length the chain should have a minimum play (3) of 10 mm (1/4 inch). See Fig: Chain adjustments. When the play in the chain is about 20 mm (3/4 inch) the chain must be tightened. Otherwise it will cause abnormal wear of the chain and sprockets. Therefore it is always recommended to keep the chain play as small as possible. Loosen the hub nut (2) on both sides and tense the chain with the chain adjuster (1) when needed.

When the chain has become so long that it can no longer be tightened with the chain adjusters it is worn out and should be replaced with a new one.

To adjust or replace the chain, remove covers if required.

To adjust the chain the hub nuts (2) should be loosened. Loosening or tightening the nuts on the chain adjusters (1) will then move the hub and axle forward or backward. Then tighten the nuts on the hub axle again. See Fig: Chain adjustments.

To replace the chain, loosen the chain adjusters as much as possible. Dismantle the chain lock (6) and remove the chain. Use a pair of tongs for dismantling spring. Put on a new chain and assemble the chain lock. The spring of the chain lock should be assembled with the closed end in the movement direction (5) of the chain. Use a pair of tongs for dismantling and assembling the spring (4). See Fig: Chain replacement.

NOTE! At assembly the ﬂywheel has to be parallel with the centerline of the frame. Otherwise the chain and sprockets make a lot of noise and wear out rapidly.

Then assemble the removed parts as above but in reverse order.

Freewheel sprocket

When replacing the freewheel sprocket remove frame covers if necessary. Remove the chain according to section ”Chain 1/2” x 1/8””.

Loosen the axle nuts and lift off the ﬂywheel. Remove the axle nut, washer, chain adjuster and spacer on the freewheel side. Replace sprocket-adaptor and assemble the new parts in reverse order according to the above.

The sprocket should be lubricated with a few drops of oil once a year. Tilt the cycle to make it easier for the oil to reach the bearing. See Fig: Lubrication.
