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

VO2 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.

Operating Instruction

Here are instructions for connections and opportunities for connection to external communication. 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.

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 left side of the flywheel.

It is also possible to use an analogue control from an external source to set the workload. This is done by the contacts b32 and z32 on the main connector on the bike.

The ergometer need not 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 RPM figures on the LCD screen are large and easy to read. The screen turns on automatically when the pedals are moved and turns off after three minutes of inactivity. See fig: RPM meter and ECG-sticker.

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.

Batteries: 2 x 1.5 V, R14

Storing temperature: -10º C - +60º C

Operating temperature: 0º C - +50º C

For information about how respective control units works, see respective sections.

Measured quantities

The Monark Ergometer 939 E can be controlled externally from a terminal, a computer or an ECG device.

The control is performed over a serial line using ANSI/

ISO/ASCII format commands. The interface is a 9-pin male D-sub connector, compatible with the RS232 standard, located on the front of the bike above the front support tube. See fig: Connections.

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 enclosed cable is to be used, or the USB-serial adaptor which is included in the PC-model.

The bike has a default setting to be used/connected to a PC or an ECG. It can also be used/connected to a terminal (option, Art. No: 9339-51). For information about the enclosed PC software please refer to the software manual.

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 Terminal unit.

Initial operation

Although all 939 E ergometers are 100 % calibrated at the factory, the user may wish to verify this by performing the mechanical calibration of the pendulum weight. See section ”Calibration of

Pendulum Weight”.

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.

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 displayed rate, should agree with the manually detected pulse rate. If not, check the patient electrode connection and skin preparation prior to requesting 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

From main menu go to any start display with Newtons

(N).

1. With the pendulum at zero, the display should read “ 0“.

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

3. Decrease the position of the weight by steps of 1 kp.

The display should read correctly at all positions.

NB: The brake belt will become loose and because of this it will take a few seconds before normal workload is obtained the first time the ergometer is used.

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

First check the brake belt tension. If the belt is too tight, loosen it a little by moving the force indicator to about 4 kp and hold it there for a few seconds. Then the force adjusting servo loosens the belt tension.

To be sure the indicator positions are correct do a calibration as follows.

1. Press the switch(2) to turn off the power, see

fig: Connections in part ”Connection to an

external unit”.

2. Adjust the scale mechanically so that 0-index

on the scale and indicator are in line.

3. Move the indicator to 4 kp and hold it there.

4. 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.)

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

heard.

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

beep.


beep.


beep.

9. 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.

Scale - zero adjustment

Connect power to the bike. Loosen possible tension in the brake belt by moving the indicator 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 adjustment.

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 measurements made with the ergometer in conjunction with the ease of testing, allow it to be employed in clinical exercise stress facilities, corporate fitness programs and health clubs. 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 consult 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. A system of communicating fatigue, chest pain or other abnormal physical response to the exercise should be discussed.

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

The test person 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. The test person 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, the chestbelt should be applied and monitored to check for proper heart rate operation. The baseline heart rate may also be of assistance in determining the nervousness of the test person. The test person 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 system)

The test person’s heart rate can be monitored by chestbelt telemetry system. The system with chestbelt electrodes 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.

If the ergometer is to be used without a chestbelt note that max heart alarm should be set in “off” position so that external noise cannot cause a random max pulse or higher. This switch is in “on” position by default. If the heart rate exceeds the maximum level set, the alarm will sound and the ergometer braking force will decrease until the heart rate drops below the alarm level.

Monitoring of the test person

The ergometer performs automated tests virtually by itself, requiring minimal intervention by the 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 to assist the test person, if necessary, may be given. The rider is subjected to considerable exercise in certain advanced protocol stages. The effect on the test person should not be underestimated.

During the testing, the general appearance and heart rate may be the most crucial factors to monitor. 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 show difficulty in regulating the speed of the ergometer. The power will be properly regulated regardless of the speed, assuming that the protocol work type is not force and that the speed is maintained above the pedal low setting (default is 30 rpm).

In addition, some test persons may become sensitive to the display on the terminal. If this is suspected, the controller may be removed from its cradle and located out of view. Similarly, the pulse LED may disturb the test person and may be disabled.

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 person 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 persons 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.

Check that the electrodes are wet, in some 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 pulse receiver (pulse 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.

Use an external unit, for example a pulse 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.

If irregular pulse remains we recommend measuring HR manually. If HR still remains irregular at workload, test person’s health needs to be examined.

No rpm reading

Unable to calibrate force

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

Check cable.

Operation interferences

It is normally considered that about 70 % of all shutdowns on small computers are caused by mains interferences, i.e. at shot 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.

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 as above for labour or shipping.

Regular service inspection and maintenance

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

Always keep the bike clean and well lubricated.

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.

• Surface treatment with a rust inhibitor, especially when the bike is clean and the surfaces are 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. 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 normal 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.

• Grind the brake belt contact surface, see section

"Brake belt contact surface" (once a year).

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 be changed.

Crank bearing

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

Flywheel bearing

The bearings in the flywheel are greased and do not normally require maintenance. If a problem arises, please contact your Monark dealer.

Manual pendulum bike / exercise bike:

To loosen the brake belt on other bikes remove all possible 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”.

Transport

At transport the brake belt 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.

Pendulum bike with engine:

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.

Weight basket bike:

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 covers and loosen the tension on the brake belt. Smoothe with fine sandpaper. This 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 sandpaper 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“

It is strongly recommended to keep the chain clean.

Dirt build-up on the chain will cause excess wear. A chain lubricant and solvent for normal road bikes may be used.

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) it must be tightened otherwise it will cause abnormal wear of the chain and chainwheels. Because of this 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 should be replaced with a new one.

To adjust or replace the chain remove frame covers if necessary.

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. Adjust according to above recommendation. Then tighten the nuts on the hub axle again. See fig: Chain adjustments.

To replace the chain, loosen the chain adjuster as much as possible. Dismantle the chain lock(6) and remove the chain. 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 chain wheels make a lot of noise and wear out rapidly.

Adjust chain adjusters to allow chain play according to above. Tighten hub nuts firmly. Replace frame covers.

Freewheel sprocket

When replacing the freewheel sprocket remove frame covers if necessary. Dismantle the chain as described in part ”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. Place the special remover (Art. No:

9100-14) in the adaptor and place the spacer and axle nut outside. See fig: Special remover. Replace sprocketadaptor 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 adaptor-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.
