Monark 939 E

Product Information

Congratulations on your new Ergometer!

The Monark 939 E 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

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

Each 939 E 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.

NOTE!

Use of the product may involve considerable physical stress. It is therefore recommended that people who are not accustomed to cardiovascular exercise or who do not feel completely healthy, should consult a physician for advice.

Operating Instruction

Here are instructions for connection and options for connection to external devices. The need for advanced technical documentation / protocols for systems building, contact Monark Exercise AB, Sweden.

Power on crank or flywheel

When the Ergomedic 939 E is adapted to fitness tests it is set to measure the power on the flywheel.

When the Ergomedic 939 Medical is adapted to

ECG work tests it is set to measure the power on the crank.

A sticker, placed on the display, see Fig: RPM meter

and ECG-sticker, informs that the ergometer is set to measure the power on the crank.

The ergometer need not to be turned off prior to connection of the external components, although removing the power from all devices may prevent erroneous data transfer between equipment during interconnection. Caution must be exercised in the connection of various types of equipment from different manufactures to avoid electrical hazards and physical damage. The user must be certain that the instrument connector and the cable are designed for the intended purpose. Serious injury to the user and / or equipment may result if inappropriate connections are attempted.

RPM meter

The LCD displays the number of pedal revolutions per minute with big numbers. The viewing starts automatically when the crank is in motion. The display turns off automatically after about three minutes if pedalling stops. See Fig: RPM meter and

ECG-sticker.

Operation of the ergometer

The Ergomedic 939 E is built on a stabile frame, a large well balanced flywheel, a break belt and a pendulum weight which measures the force. Pedals and a chain drive are provided to spin the flywheel as a tension device tightens the belt to regulate the braking force applied to the wheel. The pendulum indicates the applied force directly on the scale located on the right side of the flywheel.

The computer system consists of one main unit and one control unit (terminal, PC or ECG). The main unit reads in the pedal speed, the applied force and determines the subjects heart rate by a chest transmitter. Additionally, the base controll activates the motor to adjust the tension of the belt, thereby regulating the applied braking force. The force may be automatically varied in response to changes in pedal speed to maintain a constant power workload.

Connection to an external unit

To use the bike it has to be connected to an external device such as an ECG device or a PC. The external unit is connected to the serial data connection port (2) on the lower front of the bike. See Fig: Connections.

The supplied 0-modem cable shall be used, alt. USB adaptor that comes with the PC model.

The bike is factory configured to connect to a PC alt. a handheld controller (accessories, Art. No: 9339-

51). PC software is available for free download from our website: www.monarkexercise.se.

If the bike is going to be connected to an ECG device, you must change the settings on its internal computer.

This setting can be changed directly on the bike with the scale indicator on the left side of the bike or with an external handheld controller.

Setting using the pendulum weight is done on the bike's left side. See section "Setting command type

(PC or ECG device)".

Initial operation

The ergometer 939 E is to 100 % calibrated at the factory. But as usual when the bike has been moved, an electronic calibration must be done, see instruction for “Electronic calibration” in this manual.

Apply power to the ergometer by first connecting the cable from the power adaptor to the ergometer at the front connector, see Fig: Connections. Then plug the power adaptor into the wall outlet. Turn the power switch to on position. A green LED indicates power to the 939 E, see Fig: LED.

Perform the electrical calibration as specified in section

”Calibration Electronics”. Test ride the ergometer.

The 939 E Ergometer is now fully functional and ready to use.

Cycle adjustments

Seat height should be adjusted to a comfortable position. The appropriate height is to have the knee slightly bent when the sole of the foot is centred over the pedal axle with the pedal to the bottom position.

To adjust the seat height turn the quick release bolt

(1) on the saddle post approximately one revolution and pull it out. 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.

When using the Polar chest belt, an identification between belt and sensor has to be done at first use.

Make sure to get the pulse signal by standing close to the sensor (max. 60 cm / 23 ½").

Calibration

The 939 E is a mechanically weighted and braked ergometer, making performance validation a simple procedure. The work performed on the ergometer is the product of the weight lifted times the numbers of revolutions (factored). Validation includes both mechanical and electronic procedures. If the ergometer fails to pass any section of the validation, proceed to the calibration and/or service menu (99 in the main menu).

Inspection of all mechanical components is suggested after any repair, or component service. The following validation should be performed annually:

Validation

The following procedure will assure the user that the ergometer is performing properly on a daily basis.

The test exercises the mechanical braking, pedalling and speed detecting systems as well as the computer regulation 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 electrodes or an ear sensor, 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, call customer service.

1. Remove the cover from the flywheel.

2. Loosen the brake belt at the balancing spring.

3. Wait until the flywheel is no longer moving.

4. The pendulum weight index should be aligned with “0“ on the scale.

5. Attach the calibration weight to the point at which the spring was attached.

6. The known weight should match the value on the scale. If not see section “Calibration of Pendulum

Weight “.

7. Reattach the tension belt.

8. Reassemble the cover.

Proceed to the validation to complete.

Validation of force

To do this you need to have the bike connected to a computer with Monark software (manual mode) or that the handheld controller is used.

From main menu go to any start display with Newtons

(N).

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

2. Move the pendulum weight to the 4 kp position and the display should read “39“ Newtons.

NOTE!

After this verification, the brake belt will be loose, which means that it takes about 15 seconds before the regulating device has tense the brake belt to normal again (5 N).

12

Monark 939 E

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.

Loosen possible tension in the brake. See ”Scale - zero adjustment”. Check that scale 0-index is in line with the pointer(1). See Fig: Calibration. If adjustment is needed adjust according to ”Scale -zero adjustment”.

A checked and approved weight(4), 4 kg (Art. No:

9000-211), is attached at(5). See Fig: Calibration.

At the correct calibration, the indicator should point to 4 kp on the scale.

If there is a deviation adjust the pointer to the correct position by adjusting the weight inside the pendulum(2). To do this the left cover has to be removed.

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

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

Check the scale calibration once a year or if required due to service.

Electronic calibration

When calibrating the electronics do the following:

1. Turn off the power by pressing the power switch (2) which is placed on the frame, see

Fig: Connections. in section ”Connection to an external unit”.

2.

3.

Adjust the scale mechanically so that 0-index on the scale and indicator are in line.

Move the indicator to 4 kp and hold it there.

4.

5.

6.

7.

Turn on the power again. (The green LED on the lower left side of the bike is lit up when there is power to the bike.)

Hold the indicator at 4 kp until one beep is heard.

Move the indicator to 0 kp and wait for one beep.

Move the indicator to 2 kp and wait for one beep.

8.

9.

Move the indicator to 4 kp and wait for one beep.

Move the indicator to 6 kp and wait for two beeps.

10. Move the indicator to 0 again.

Calibration is done.

The indicator can now be used to set the bike in different modes.

Testing with Ergomedic 939 E

The versatility of the 939 E / 939 Medical Ergometer 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, whether in a clinical laboratory or a health club, the subject may be exercised quite strenuously, depending on workloads which have been selected. As a precaution, it may be advisable, prior to beginning an exercise protocol, that each subject consults with a physician.

Before testing, the operator should review the entire protocol operation with the test subject, explaining the work which will be required and the duration of the procedure. A system of communicating fatigue, chest pain or other abnormal physical response to the exercise should be discussed.

The test subject 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 also refrain from smoking within an hour of the testing period.

The test person shall also have the appropriate clothing for a work test. Training suit or loose-fitting clothing is best. The test subject may need some general education concerning the pedalling of the ergometer. The saddle and the handlebars should be adjusted for comfort and proper mechanical distance.

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 to the bottom position.

The operation of the speed metronome and over/ under display should be reviewed.

The maintenance of the proper speed should be practiced at a low workload.

Finally, put the chest belt on. Check for a minute that a proper heart rate is displayed. The baseline heart rate may also be of assistance in determining the nervousness of the test subject. The test subject should exhibit a relatively stable resting heart rate prior to starting the protocol.

Power calculation

1 rpm = 6 m on the flywheel brake surface.

50 rpm = 300 m

2 kp force makes 2 x 300 = 600 kpm/min

100 rpm= 600 m

1 kp force makes 1 x 600 = 600 kpm/min

(watt = rpm x kp)

Monark 939 E

Heart Rate (telemetry)

The test subject’s heart rate can be monitored by chestbelt telemetry system. The chest belt is standard equipment.

Fuss-free HR measurement requires that the 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 of the chest belt. Moisten the electrodes before use, see Fig: Electrodes on the

back of the chest belt. To make contact with the HR receiver on the bike, the distance should not be more than 100 cm. It is especially important when first used to identify the chest belt with the sensor, by standing close to get the HR (maximum 60 cm). This relates especially to the Polar heart rate belt.

NOTE! Electromagnetic waves can interfere with the telemetry system. Cellular phones are not allowed to be used near the bike during test.

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

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 subject 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 activity. The effect on the test person should not be underestimated.

During the test it is important to observe the subject person's appearance and heart rate. The testing should be stopped immediately if the test person reports chest pain, difficulty 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 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

35 revolutions / min (rpm)). However, it is important to consider what each test documentation says about the pedal speed.

Reviewing results

The maximum oxygen uptake is the standard measurement of cardiopulmonary fitness. 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.

The 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 Bruce and Naughton protocols require that the test subject exercise at a workload level for a minimum of one minute to establish the oxygen consumption.

If less than one minute is observed, the previous workload value is used.

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 subjects who are less familiar with bicycle exercise and those individuals who are less fit, are more likely be less efficient than those who ride bicycles 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.

A relative fitness index can be obtained from the following table:

Trouble shooting guide

Symptoms Probable Cause / Corrective Action

LED does not light up

No connection to PC

No workload

No heart rate is displayed

No rpm reading

Unable to calibrate force

Uneven heart rate

There is a click noise with every pedal revolution (increases with the weight)

Scratching sound is heard when pedalling

There is a click noise and a squeak noise when pedalling

Any problems with the computer software

No current in the outlet. Check the fuses.

Right transformer? Check so that the trafo information in section “Facts” is in accordance with the trafo used.

Looseness in the cord (directly on the box). Contact service centre for action / replacement.

Power switch (on / off).

Check cables.

Right COM port?

Drivers missing when using the USB-serial adaptor. CD with drivers is included.

Is the right type cmd set? "Start beep" = cmd type, see section "What commandotype is set".

Pendulum stuck. Contact service centre for action / replacement.

Looseness in the motor connector. Contact service centre for action / replacement.

Check that the pedal speed is higher than 30 rpm. No workload is put on if the actual pedal speed is lower than 30 rpm. See "Service menu" pedal reference. The default setting is 30 rpm but can be adjusted to the desired value.

Check calibration.

Check the chestbelt (battery). Wet the thumbs and place them on the electrodes. A low clicking sound will appear near battery lid while you click on the electrodes with one thumb. Use another external HR monitor to check the belt.

Check that the chest belt is positioned correct on test person and tight enough. Check that the electrodes are wet, in hard cases it is necessary to use a contact gel or a mixture of water with a few drops of washing-up liquid. The level for HR signal can vary from person to person. Put chestbelt on another known person who has a good pulse rendering.

Check for loose cables or jack if you have a plug-in receiver. Use another HR receiver

(HR watch or test bike monitor) to check the chestbelt.

Check that it is the correct receiver and that it is in the correct place. If it has a round

Polar-sticker it should be placed straight.

Check cable.

Potentiometer belt may be slipping or broken. Replace if damaged.

The potentiometer is misadjusted. Reboot memory from service menu (99). Set default

(3). Then calibrate the electronics again.

Use an external unit for example a HR watch to check if it also indicates irregular pulse. If this is the case, there is probably disturbance in the room. Magnetic fields from high voltage cables, elevators, fluorescent tube etc. can cause the disturbance. Other electronic equipment could be placed too close. Move the bike to a different location in the room or change rooms. If an irregular HR remains it should be checked manually

If the HR remains irregular at work the person's health should be examined.

The pedals are not tight. Tighten them or change pedals.

The crank is loose. Check, tighten.

The base bearing is loose. Contact your dealer for service.

Check that the carriage block is taken off and that none of the covers is scratching.

Loosen the chain.

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 mains and the transformer.

Service

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

Warning

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

Warranty

EU countries - Private use

If you are a consumer living in the EU you will have a minimum level of protection against defects in accordance with EC Directive 1999/44/EC. In short, the directive states that your Monark dealer will be liable for any defects, which existed at the time of delivery. In case of defects, you will be entitled to have the defect remedied within a reasonable time, free of charge, by repair or replacement.

EU countries - Professional use

Monark Exercise products and parts are guaranteed against defects in materials and workmanship for a period of one year from the initial date of purchase of the unit. In the event of a defect in material or workmanship during that period, Monark Exercise will repair or replace the product. Monark Exercise will not, however, refund costs for labour or shipping.

Other countries

Monark Exercise products and parts are guaranteed against defects in materials and workmanship for a period of one year from the initial date of purchase of the unit. In the event of a defect in material or workmanship during that period above, Monark

Exercise will repair or replace (at its option) the product. Monark Exercise will not, however, refund costs for labour or shipping.

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. I.e. 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.

Batteries

If the meter 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.

Alt. 3: To loosen the brake belt on the bike remove all tension. 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”.

Crank bearing

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

Flywheel bearing

The bearings in the flywheel are lifetime greased and require normally no maintenance. 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.

Alt. 1: 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.

Alt. 2: To loosen the brake cord on cycles with a weight basket set the basket to its upper position.

Loosen the lock washer that is holding the cord and remove it from the tension center. Loosen or cut of the knot in the other end of the cord and then remove the hole cord from the bike. When assembling a new brake cord, first enter one end into the hole in the tension center, and tie a knot and let the knot fall into the bigger part of the hole. Lock the end of the cord with the lock washer.

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 little 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 shall 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 parallell with the centerline of the frame. Otherwise the chain and sprockets makes a lot of noise and wears 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-adapter and assemble the new parts in reverse order according to the above.

NOTE! Do not tighten the axle nut completely. It must be possible to loosen the adapter-sprocket half a turn.

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.
