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.

NOTE!

Use of the product may involve considerable physical stress. It is therefore recommended people who are not accustomed to cardio or do not feel completely healthy to consult a physician for advice before use.

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.

Operating Instruction

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.

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.

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.

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

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.

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.

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.

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 a Polar chestbelt it is important initially, to identify the chestbelt with the pulse receiver by standing close to it (max 60 cm).

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.

Fig: LED (1) (Left side in front of rear support tube.)

Monark 939 E

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 will loosen the belt tension. To be sure that indicator positions are correct, do a calibration. See ”Electronic calibration”.

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

Adjust the scale mechanically so that 0-index on 2. the scale and indicator are in line.

Move the indicator to 6 kp and hold it there.3. Turn on the power again. The green LED on the 4.

lower left side of the bike is lit up when there is power to the bike.

Hold the indicator at 6 kp until two beeps are 5. heard.

Move the indicator to the settings that 6. correspond with the type of external unit you are

connecting to: 0 = mode for use with PC or hand unit. 1 = mode for Siemens Megacart ECG 2 = mode for other ECG devices, alt 1. 3 = mode for other ECG devices, alt 2.

7. Hold at this position until two beeps are heard and after that, move the indicator to 0 again. The system will now restart in chosen mode.

Connection to controller

Monark 939 E

Connection to PC

To connect a PC to the ergometer, use a 0-modem cable (RS232) with a 9-pin D-sub female at each end. If no RS232 Serial port is available on the computer use a USB serial RS232 converter.

Before installing the Monark Software for your ergometer, you must take the following steps.

Locate the USB adaptor. 1. Inside the USB adaptor packaging, there is a mini-2.

CD. Insert the mini-CD into the CD-ROM drive and 3.

install the driver software. If there is no CD drive on your computer, driver software is available for down from the website (http://www.vscom.de/ USB-CD).

Finalize the driver software installation by inser-4. ting the USB adaptor.

Install the Monark Software disk. 5. Connect the USB Adapter to the Serial Cable and 6.

proceed with testing.

To control the ergometer use the PC software supplied with the ergometer or other PC software made for the Ergomedic 939 E.

From software version MEC3V11R14 and later settings can be made from a PC in terminal mode if the terminal is not available. Set PC in terminal mode. A terminal emulator is normally available in i.e. Windows under Accessories/Communication.

If no RS232 serial port is available on the PC use a USB serial converter to connect to a USB port. In terminal mode do the following settings:

Connect Ergometer and PC with the 0-modem cable (normally used for the ergometer terminal). Turn on power to the ergometer. The ergometer is now checking what type of device is connected. When ﬁnished a message appears on the PC screen.

Common commands:
