Product Information

Thank you for choosing a test cycle from Monark!

The Monark 928 E G3 / 928 G3r is designed to, in a simple way, be used for submaximal exercise test and make calculations of the maximum oxygen uptake. The bike can also be used for normal exercise.

Ergometer 928 G3 is equipped with a meter that is available in two versions - 928 G3 and 928 G3r 928 G3 has 6 different programs and 928 G3r has two programs. The cycle can also be connected to a computer with software for testing (software is available for free download from our website: www. monarkexercise.se).

The G3 models also have a new and more powerful engine for faster power control.

For more detailed description of the meter's functions, see the section "Display Description".

All 928 G3 and 928 G3r are calibrated at the factory. This means that you can begin to use the ergometer directly after assembly. However, if the user wishes to verify the scale calibration please read the instruction for ” Calibration” in this manual.

Operating Instruction

Workload adjustment

A change of the workload is done either by changing the pedal speed or by pressing (+/-) button on the meter to increase or decrease the brake belt tension on the ﬂywheel. See Fig: Workload adjustment and

connections.

Power measurement

The cycle is designed to measure the power on the ﬂywheel, because tests/protocols are made for it (for example Åstand’s and YMCA).

Power Connection

The bike is designed to be used with the AC adaptor which is included with the bike. Connects (3) to the bike as shown in Fig: Adjustments.

Fig: Adjustments

1) Locking knob, saddle

2) Locking handle, handlebar

3) Connection unit

Fig: Workload adjustment and connections

1) USB

2) Workload (+/-)

Connection to an external unit

When the USB connector is inserted or when the meter detects a connected computer, you will hear a quick double beep. An icon for the USB lights in the display. Otherwise, the meter will turn off except rpm and HR. When the meter is connected to a computer, it turns to passive mode. No buttons are active except HEART button (to pairing the display and chest belt).

The socket for the USB connector (1) is shown in Fig: Workload adjustment and connections.

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.

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.

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

Cycle adjustments

When adjusting the seat height:

Turn the knob (1) on the seat post and pull it out. Adjust the height and lock the knob again.

Handlebar settings

To adjust the handlebar angle loosen the quick release lever (2). See Fig: Adjustments.

The user's heart rate can be measured with a chest belt that senses the electronic output of the heart. Chest belt ANT+ is supplied as standard.

Fuss-free HR measurement requires that the belt is correctly placed. Make sure that your skin is clean where the chest belt should be placed. When it is correctly ﬁtted the logo on the belt will be central and readable, outward and upright, by another person. 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: Moistening the electrodes.

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

Pulse standard (chest belts)

The following pulse standard / chest belts can be used:

Standard, uncoded 5K chest belts (5-5.6 kHz)• Chest belts with ANT+•

Short range ANT+: 0.6-0.8 m (24"-31 ½") Long range ANT+: 4-5 m (13-16 ft) Range 5K: 0.8 m (31 ½")

Pairing display and chest belt

Normally the display connects to the ﬁrst ANT+ chest belt in "short range" and shows the heart rate until the chest belt is outside the "long range". If there is no ANT+ chest belt but a 5K chest belt in "short range", the heart rate from the 5K chest belt is displayed until the signal is lost.

ANT+ is prioritized and the ﬁrst choice of the display. 5K is discriminated, but after 30 seconds with only 5K the display is locked to this chest belt as long as you do not lose the signal.

Pulse function

Monark Exercise AB recommend that you

use an ANT+ chest belt for best function.

Cycle constant

The cycle constant is as default set to 1.00. Change using the (+/-) button.

When the cycle constant is set to 1.00 the power is measured at the ﬂywheel. This is used in Astrand test, YMCA etc.

When the cycle constant is set to 1.05 the power is measured at the crank. This is often used on electronically-braked bikes.

Metronome cadence

Metronome diodes show pedalling revolutions (rpm) relative to the set reference value. The metronome is located at the back of the meter. The default value is 60 and can be adjusted with (+/-) button. The green LED in the middle ﬂashes twice for each pedal revolution which helps to keep the right pedal cadence, see Fig: Display and Fig: Metronome.

The meter can be rotated so that the rider does not see the values in the display, but only sees the ﬂashing diodes (in order to keep the right pedal cadence).

If START STOP is pressed, or if no button is pressed for 20 seconds (in all steps), the changes are saved and the display returns to normal with the new settings active.

Scale - zero adjustment

Connect power to the bike. Loosen possible tension in the brake belt by moving the indicator to 0.5 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 pointer. Tighten the lock nut after the adjustment. See Fig: Scale

adjustment.

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:

First, follow the steps in the "Scale - zero • adjustment”. Adjust the pendulum if necessary.

Loosen the calibration hook from the hook • bracket, 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. Note! The calibration hook should always be left in the hook control.

If the calibration is correct, the indicator should • point to 4 kp on the scale.

Lift off the weight and replace the calibration • hook in the hook bracket, see Fig: Normal mode. Note! The hook must be inserted in the holder during operation.

If there is a deviation, adjust the pendulum to the right position on the scale by adjusting the weight inside the pendulum (2). To do this the left cover must 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 calibration of the pendulum weight once a year or when needed.

METS

During the test METS and l/min are continuously counted and displayed.

Calculation

METS values are displayed and calculated from the current workload. The two VO

values displayed during the test continuously calculate the average value for 5 seconds.

The formula used (values from ASTRAND original table) to calculate VO

2

at different workloads is:

0.2333 ... l / kpm = 0.01428 L / W (2.8 l / min at 1200 kpm)

This is according to Astrand's table between 150 W and 300 W, and a good approximation for 15-700 W and a cadence of about 50-65 rpm.

The test is automatically stopped after six minutes if Steady State (SS) is active. If not, the test continues until SS is reached or the time reaches 12 minutes.

Steady State (SS) is checked by comparing the average HR during the period 4:45 to 5:00 with the average HR during the period 5:45 to 6:00. If the difference between these two average values is the same or less considered SS.

When the test is completed the results are calculated and shown directly in the display.

You can stop the test manually after six minutes by pressing START STOP even if SS is not active (an error message is shown). The result is calculated and displayed.

Test procedure

The display begins with the start power (which is speciﬁed in "Start Power") and begins the countdown to the next step. The display will increase the power at the speciﬁed power increase each time the set time has passed and a new countdown begins. At the same time you hear a beep.

The test is automatic after it has been started.

If the test is stopped because of the low rpm it starts automatically even if the rpm increases again.

About Increment test Increment is a testing protocol, where the power is

increased according to a predetermined schedule. An increment is used to see the HR increase in relation to the rising power. It is used in both submaximal to maximal tests to track the maximum capacity.

The test continues until the test manager or test person cancels the test.

PWC test level The meter suggests a level based on your age. Can be adjusted with (+/-) button.

PWC target HR watt calculation:

The estimated watt value at target HR (WPT) is calculated from the following data:

W1 = Watts value set in penultimate step W2 = Watts value set in the last step P1 = 15-second average HR at the end of the

penultimate step P2 = 15-second average HR at the end of the last

step PT = Target HR: 130, 150 or 170 beats / min

Formula for the WPT: WPT = W1 + (W2-W1)x(PT-P1)/(P2-P1) [W] Relative WPT: WPT / kg = WPT / Weight [W / kg] For further information please refer to the reference

literature.

Power step

The display shows time 2:00 and power 25 W. Switch with (+/-) button to time 3:00 and power 50 W. Press ENTER to save.

Start power

The display shows "Init". Set the initial power of the ﬁrst step between 25 and 400 W with 25 W steps. Default value is 25 W. Press ENTER to save.

How it works

At the end of each step calculated average HR during the last 15 seconds, a beep sounds, 25 W or 50 W is applied workload, and a new countdown starts. In the ﬁrst ﬁve seconds of the next steps the display shows test time, workload and estimated average HR during the previous step. During these ﬁve seconds the values ﬂash.

This continues until the 15-second average HR is higher than the target HR (130 / 150 / 170). Then the test is stopped, a beep sounds, the workload reverts to start power, the ﬁnal 15 seconds of average HR is displayed. The text "COOL" is displayed and the sixminute countdown starts. A 15-second average HR is displayed after 1, 3 and 5 minutes of the countdown.

You can skip the "cool down" by pressing the START STOP and the results appear instantly.

Troubleshooting guide

Symptoms Probable Cause / Corrective Action

The Display is not working Check that there is power in the socket and that no fuse has blown. •

If there is power in the socket but the display still does not work, •

contactthe•servicecentre.

No heart rate Check the chest belt (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 correctly on test person and • tight enough. Check that the electrodes are wet, in difﬁcult 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 chest belt on another known person who has a good pulse reading.

Uneven Heart rate Use an external unit, for example a HR watch, to check if it also •

indicates irregular pulse. If this is the case there are probably a disturbance in the room. The disturbance may be electronic ﬁelds from power cables, elevators, lamps etc. or other electronic devices which are too close (eg. cell phones). 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.

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.

Monark 928 G3 / 928 G3r

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.

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”.

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”.

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.

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.
