Product Information Facts Congratulations on your new ergometer. • • • • • • • The Monark Ergomedic 839 E is one of the world's most precise and user-friendly computerized pendulum ergometers. The Ergometer is controlled by either a control unit, an external PC or other external units. The bike can perform max and submax fitness tests and calculate the VO2 max. The ergometer can be connected to ECG to do work tests. It is possible to build personal programs that are custom made for the user.
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 839 Medical is adapted to ECG work tests it is set to measure the power on the crank. When the Ergomedic 839 E is adapted to fitness tests it is set to measure the power on the flywheel.
Rpm Meter and visual Metronome / Puls Initial operation 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. 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”.
Connection to controller Setting of terminal Setting of command type (PC or ECG device) When using a terminal (Art. No: 9339-51) do as From software version R15 First check the brake belt tension. If the belt is too tight loosen it a little by moving the pendulum to about 4 kp and hold it there for a few seconds. Then the force-adjusting servo will loosen the belt tension. To be sure that pendulum positions are correct, do a calibration. See ”Electronic calibration”. 1.
Connection to PC In terminal mode do the following settings: - 9600 baud - 8 data bit - 1 stop bit - no parity - no flow control - set terminal emulation to VT100 - set the COM port number. A USB serial converter is automatically assigned to a COM port number by Windows. This number is indicated under Startmenu / Settings / Control Panel / System Hardware. To connect a PC to the ergometer, use a 0-modem cable (RS232) with a 9-pin D-sub female at each end.
Connection to an external ECG device, digitally controlled (if terminal is used) 1. Connect the terminal via the supplied 0-modem cable (9-pol. D-sub female connector on each end) to the corresponding connector (5) in the front end of the cycle, see Fig: Connections. 2. Connect the net adaptor to a suitable wall outlet and to the connection (3) on the bike and then turn power on. 3. After a short while the main menu is shown on the terminal's display. 4.
Analogue control Printer The workload of the Ergometer can be controlled by external devices such as an analog ECG device (must be between 2 and 4 volts to operate properly). For settings, see the manual for the terminal and the manual for the software. A parallel interfaced printer may be attached to provide written reports. Start by connecting the printer to the parallel output (1) located on the front of the bike.
Calibration Daily check The 839 E is a mechanically weighted and braked ergometer, making performance validation a simple procedure. Calibration is necessary to match the mechanics of the ergometer to the electronics of the computer. 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. For more information, see Manual terminal (art. No: 7950302) or the manual of the software.
Validation of force Electronic calibration From main menu go to any start display with Newtons (N). See Fig: Force. A daily check of the pendulum force sensor should be preformed. If the procedure reveals an error, recalibration may be necessary. The values are saved even if you turn off the power and if you physically move the bike.
Electronic calibration - terminal Electronic calibration - with the pendulum 1. Check at the bottom of the flywheel that the brake belt is loose, see Fig: Brake belt is loose. If not, move the pendulum to 4 kp and hold it there for some seconds. Move the pendulum down to 0-position again, and check that the brake belt is loose. 2. Adjust the meter panel, see section "Zero adjustment of meter panel", so that the index line of the pendulum is opposite the 0-index of the scale, see Fig: 0-position. 3.
Fig: Check loose brake belt.
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 from the flywheel. Loosen the balancing spring from the brake belt. Check that the 0-index of the scale is in line with the index of the pendulum weight. If adjustment is necessary, loosen first the lock nut.
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 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.
Heart Rate (telemetry system) Subject supervision A person's heart rate can be measured with a chest belt that senses the electronic output of the heart. The chest belt is standard equipment. 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 subject without distraction.
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.
Troubleshooting guide Symptom Probable Cause/Corrective Action LED does not light up. No current in the outlet. Check the fuses. Right trafo? Check that the trafo information in section “Facts” is consistent with the trafo used. No connection to PC. Check cables. Right COM port? Drivers missing when using the USB-serial adaptor. CD with drivers is included. Is the right type cmd set? Does not load work. The pendulum stuck Contact the service for fix / replacement.
Error messages Message Reason "Test Aborted" An automatic protocol operation has been stopped too early. No results are available. 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.
Where to obtain additional information The user may require more information concerning several areas of the ergometer usage. This manual was intended to instruct the reader primarily in the operation of the ergometer. References are made to related topics in the discussions concerning the testing procedures and the protocol operation sections. The following literature may provide some greater insight to ergometer-based testing without confusing the reader with technical medical terms.

Service Service check and maintenance Note that the text about service and maintenance is universal and that all parts may not be relevant to your bike. To keep your Ergometer in good shape you should make a regular service. Service action: Warning Make sure the voltage indicated on the appliance corresponds to the local mains voltage before making connections.
Batteries If the meter i sbattery-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. the lock washer. Crank bearing NOTE! When replacing the brake belt it is recommended to clean the brake surface. See ”Brake belt contact surface”. The crank bearing is long term greased and require normally no supplementary lubrication.
Chain 1/2“ x 1/8“ Check the lubrication and tension of the chain in 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.
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. Special remover (Art. No: 9100-14) in the adapter and place the spacer and axle nut outside. See Fig: Special remover NOTE! NOTE: Do not tighten the axle nut completely. It must be possible to loosen the adapter-sprocket half a turn.
