Operation of the ergometer

Ergomedic 839 E is built on a stable 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 control activates the motor to adjust the tension of the brake 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.

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

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.

Operating Instruction

The Monark Ergometer 839 E can be controlled externally from a terminal, a PC or an ECG device. Direct printer connection port.

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 main unit.

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

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.

Cycle adjustments

Do not forget to remove the transport protections (the transportation bracket on the weight lever, the protection tape on the ﬂywheel and the transport blocks above and below the ﬂywheel).

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 in the bottom position. To adjust the seat height loosen the lever (1) on the seat tube. 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.

NOTE! The handlebar stem should be inserted into the frame tube at least 3 inches (about 8 cm). This measure is marked with “MAX” on the stem (3).

Initial operation

The ergometer 839 E is to 100 % calibrated at the factory. The user may wish to verify this by performing the mechanical calibration of the pendulum weight. See ”Electronic calibration”.

Apply power to the ergometer by ﬁrst connecting the cable from the power adaptor to the ergometer at the front connector labelled "24VDC / 18VAC". Then plug the power adaptor into the wall outlet. Turn the power switch to on position. A green LED indicates power to the 839 E.

Perform the electrical calibration as speciﬁed in section "Electronic calibration”. Test ride the ergometer. The 839 E Ergometer is now fully functional and ready to use.

Rpm meter with optical pulse / metronome

The metronome (the two green LED bars in the middle) ﬂashes once per pedal stroke at a preset rate. The two green LED bars in the middle can also be set to show pulse. Pedal frequency compared to metronome rate is always shown.

Underspeed: Pedal speed is lower than desired metronome rate 2, 4, 8, 16 or more depending which LED bar that indicates.

Overspeed: Pedal speed is greater than desired metronome rate 2, 4, 8, 16 or more depending which LED bar that indicates.

Calories

There have been different theories on how to calculate this, since it depends on several factors and this means that it can only be seen as an estimate.

We have chosen the following formula that we think complies with the results given for a standard cycle position.

As a standard calculation when we display calories on our calibrated bikes we use: 1 minute with 100W gives 7 kcal.

It is easy to convert watts to calories if it was on the ﬂywheel (the formula is 1W=0,2388x10

-3

kcal/s with four decimals), but when you normally show calories you want to show the total amount of calories your body has used during your training, not only the calories "burnt" on the ﬂywheel.

Analogue connection

The ergometer's work load can be controlled by external analogue equipment such as ECG (must be between 2 and 4 volts to function properly). For settings on this, see the manual for the handheld controller or the manual for the computer program.

Printer

A printer can be connected to print reports.

Start by connecting the printer to the parallel output (1) located on the front of the bike. The handheld controller or computer connects both through a serial data cable to a 9-pin D-sub connector (5) located on the front of the head at the parallel port, see Fig:

Connections.

If the external device is a desktop printer it must be capable of emulating Epson alt. IBM Proprinter mode to operate. Verify that the System set-up have been set to enable automatic printout. If it has been disabled, no output will reach the device until it has been enabled. Also, the baud rate, 4800 baud, selected by the interface cable must match that of the device.

Paper must be in the printer and the choice of units must be made before the printer is in use (see user manual for the printer).

The automatic printout length is a pre-set to eleven inch pages for standard fanfold or zee-fold paper. At the top of the each page, a header designating the columns is printed. The time period between the printing of each line may be set as desire, from 0 (continuous output) to 255 seconds in one second increments. The standard setting is 15 seconds between printouts. This provides reasonable documentation while not wasting large quantities of paper.

Calibration

The 839 E is a mechanically weighted and braked ergometer, making performance validation a simple procedure. 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). Validation includes both mechanical and electronic procedures. For more detailed information, please see the manual for the handheld controller (Art. No.: 7950-301) or the computer software's user manual. 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:

Remove the cover from the ﬂywheel.1. Loosen the brake belt at the balancing spring.2. Wait until the ﬂywheel is no longer moving.3. The pendulum weight index should be aligned 4. with “0“ on the scale. Hang the calibration weight in the spring, see 5. Fig: Calibration weight. The known weight should match the value on the 6. scale. If not see section “Calibration of Pendulum Weight “. Reattach the tension belt.7. Reassemble the cover.8.

Then go ahead and perform the daily check which is also a part of the annual inspection.

Fig: Calibration weight

Validation

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

Check the pulse function, see section.• Check the brake force, see section.• 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. Fix if necessary. Check / adjust handlebars and seat and check they • are secure. 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.

Checking the pulse function

While the patient rests, with the chest belt on, the pulse indicator ﬂashes once per heart 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. See Fig: Placement of

the chest belt and Fig: Electrodes on the back of the chest belt. If this fails, call customer service.

Validation of force

From main menu choose any test and go to the start display where the braking force in N appears. See Fig:

Force.

With the pendulum pointer at 0, the display should 1. read "00N". Move the pendulum weight to the 4 kp position 2. and the display should read “39“ Newtons.

If the braking force is not displayed correctly, an electronic calibration must be done. See section "Electronic calibration".

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).

Electronic calibration

Fig: Force 1 Force in the display of the handheld controller 2 Force i the PC software

A daily inspection of the pendulum viewing against the electronics should be done. If these do not match you should recalibrate cycle. The values are saved even if you turn off the power, if you physically move the bike. Usually it is not necessary to recalibrate the cycle electronically, but it should be done after each service, change of electronic part, movement, if you adjusted the 0-index, or after you have programmed the "Reset" by default settings. (Handheld controller: alt. 99 in the main menu and then alt. 3 in the service menu.)

The following steps show how electronics are calibrated against the pendulum.

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.

A check of the electronic calibration can be done in the PC software. Choose any test. In the dialog box that appears, you can read "Force [N]." If a handheld controller is used, choose any test. In the display you can see the force at the N in the display. See Fig: Force.

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).

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.

Remove the cover over the ﬂywheel. Loosen the spring from the brake belt. Check that scale 0-index is in line with the index of the pendulum. If adjustment is required, ﬁrst loosen the locknut. Then change the scale so that the index of the sinker is consistent with 0-index of the scale. Retighten the lock nut after adjustment.

A known weight, calibration weight 4 kg (Art. No.: 9000-211), is hung in the spring.

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

This weight (4 kg) can, when properly adjusted, be read at the corresponding point on the scale. If there is a deviation, adjust the pendulum to the right position on the scale by adjusting the weight inside the pendulum. To change the position of the adjusting weight, loosen the lock screw. 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 calibration of the pendulum weight once a year or when needed.

Attach the ﬂywheel cover.

Zero adjustment of scale

Check the 0-index of the meter scale (5) is in line with the index of the pendulum. If adjustment is necessary, ﬁrst loosen the locknut (3) and then change the position of the board. Tighten the locknut after the adjustment. See Fig: Calibration.

Testing with Ergomedic 839 E

The versatility of the 839 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, one should note that stresses on the tested person can become quite severe, whether in a clinical work test or a simple ﬁtness test in physical activity contexts. 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 tested 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 in the bottom position.

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

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.

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. Test person's reactions during the test can be observed and any necessary help can be given during the test. 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 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 show difﬁculty in regulating the speed of the ergometer. This is of minor importance (except in cases where the program is based on braking force because the effect is automatically adjusted to the correct value, as long as the rpm is 30 rev / min.

In addition, some test persons may become sensitive to the display on the handheld controller. 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 subject and may be disabled.

Heart Rate (telemetry)

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

The chest belt should be secured at a comfortable tension around the mid section, just below the breast muscle. Moisten the electrodes before use. Heart rate monitoring, free from artifact, requires good electrode contacts and adequate skin preparation. To make sure that you have found the correct position the logo should have been placed in the center of chest and also be readable by another person. Prior to placing the electrodes, the test subject’s skin at the electrodes sites, should be cleaned with a commercial skin prep solution. After the chestbelt is placed the heart rate will be displayed and the heart will verify each beat. To make contact with the HR receiver on the bike, the distance should not be more than 100 cm / 39 1/3". 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). Applies particularly Polar chest belts.

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

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 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.

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

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

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.

Warning

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 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.

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.

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 off the knot on the other end of the cord and then remove the whole 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.

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 section ”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 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 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.

NOTE! Do not tighten the axle nut completely. It must be possible to loosen the sprocket-adaptor 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.
