3. PRINCIPLES OF OPERATION

3.1. BLOCK DIAGRAM

The block diagram of the machine is shown in the figure below:

3.1.1. DISPLAY

It consists of various components that will be individually described below:

Page 3.1

GLIDEX 600 XTPRO: Service & Maintenance Manual - rev. 1.1

CARDIO RECEIVER

It is connected to the machine’s CPU board and receives the pulses sent by the transmitter. There are 2 types of receiver:

• Non-coded: this is the standard product.

• Coded: this is the product which, utilizing Personal Coded Device technology, receives the

heart rate together with a code that identifies the transmitter in question. In this way the machine can identify the source of the heart rate signal, thereby avoiding interference problems.

Its reception area is approximately a circle of 1 meter of radius. If there is electromagnetic noise (produced by high voltage lines, radio transmitters, monitors, motors, etc.) within its reception area, the receiver becomes saturated and stops receiving any signal. If it is non-coded and there are 2 transmitters within its area of reception, it will receive signals from both, and may produce an error or irregular reading.

CPU BOARD

This is the heart of the machine, which controls all the machine functions by executing the program stored in EPROM. It receives information from the user (age, weight, etc.) during set-up of the training session, from the cardio receiver and/or the HS interface board (user’s heart rate) and from the alternator interface board for displaying workload data (Watt and SPM). It controls the difficulty level selected with the “+” “−” keys or according to the chosen training program.

3.1.2. CARDIO TRANSMITTER

It is worn by the person using the machine, and transmits to the cardio receiver one pulse for every heart beat that is detected. There are 2 types of transmitter:

• Non-coded: this is the standard product;

• Coded: this is the product which, utilizing Personal Coded Device technology, transmits the

heart rate together with a code that identifies the transmitter in question. In this way, the coded receiver on the machine can identify the source of the heart rate signal, thereby avoiding interference problems.

3.1.3. HS INTERFACE BOARD

This circuit board manages the hand sensors, interfacing them to the CPU board. It processes the analog signal received from the sensors and outputs one pulse for every heart beat detected, with positive logic: the signal is normally at 0 Vdc, and is asserted to 5 Vdc (with a pulse whose amplitude of approximately 30 msec) each time a heart beat is detected.

There are 3 jumpers on this circuit board, which must be configured as indicated in the table below:

Jumper Configuration

JP1 Open JP2 Closed JP3 Closed

3.1.4. RJ45-RS232 BOARD

This circuit board provides the machine connections to external devices:

Page 3.2

GLIDEX 600 XTPRO: Service & Maintenance Manual - rev. 1.1

• 1 serial port for connecting to the TGS reader;

• 1 serial port, currently not used, for future connections;

• 1 RJ45 port for the power supply to the portable Cardio Theater unit.

3.1.5. POWER SUPPLY

Receives the mains voltage at its input and outputs the DC voltages (+5 Vdc, +12 Vdc and −12 Vdc) which supply the display and the alternator interface board.

The machine uses only +5 Vdc and +12 Vdc.

3.1.6. ALTERNATOR INTERFACE BOARD

Receives from the display a square-wave signal whose frequency is proportional to the selected level of difficulty, and converts it into a DC excitation voltage for the alternator. Receives the RPM signal from the alternator, which it filters and sends to the display for calculating the speed.

3.1.7. ALTERNATOR

Is put into rotation by the user, and generates a resistance to the movement proportional to the excitation voltage received from the alternator interface board. It also generates the RPM signal (6 impulses per revolution) necessary for counting the number of revolutions and hence measuring the speed. Its rotation produces energy which is dissipated by the power resistor.

There is a thermal cutout connected in series with the excitation circuit, which is normally closed and opens when the temperature exceeds an established threshold.

3.1.8. POWER RESISTOR

Has the function of dissipating the energy produced by the alternator.

Page 3.3

GLIDEX 600 XTPRO: Service & Maintenance Manual - rev. 1.1

3.2. ALTERNATOR CONTROL

3.2.1. MECHANICS

The movement of the pedals and of the levers turns the alternator by means of a belt.

The resistance perceived by the user results from a combination of 2 factors:

• electrical component: consisting of the resistance generated by the alternator, and which can be

measured as the electrical power dissipated on the resistor, also taking into consideration the alternator efficiency;

• mechanical component: consisting of the mechanical efficiency of the linkages and more

generally of the mechanical friction of the system.

The alternator interface board is factory-calibrated by means of the 2 trimmers PT1 and

PT2 situated on the board itself. This is a purely electrical adjustment and should not be modified, even in cases where the perceived resistance of adjacent machines is different.

3.2.2. CONTROL

To control the difficulty level of the workout, the machine adjusts the excitation of the alternator which generates a resistance to the movement that is proportional to the excitation level. To do this, the CPU board transmits a PFM (Pulse Frequency Modulation) signal. The alternator interface board converts the PFM signal into an analogue signal which serves as the excitation signal for the alternator. The higher the level of the alternator excitation signal, the greater will be the resulting resistance.

The alternator rotates in the field produced by the excitation signal, generating electrical energy which is dissipated by the power resistor.

There is a closed control loop between the alternator interface board, the alternator and the resistor. In fact the alternator interface board regulates the excitation signal so that the voltage measured at the resistor terminals matches the voltage programmed by the CPU board via the PFM signal.

If the excitation signal is not sufficient to generate the required resistance, the red LED

on the alternator interface board goes on.

The rotation of the alternator also generates a square wave signal proportional to its speed, with 6 pulses corresponding to one complete rotation of the alternator. This signal enters on the interface alternator board where it is filtered and sent to the CPU board.

If the CPU board does not receive the speed signal, which means that the alternator is

not rotating, it does not transmit any PFM signal. Therefore the alternator does not receive the excitation signal and there is no resistance at all.

3.2.3. THE CONTROL SIGNALS

The machine controls the difficulty level of the workout by means of the CPU board, the alternator interface board and the alternator, as illustrated in the figure below:

Alternator interface

CN2

The following signals are involved in the control loop:

• Excitation signal (PFM and Ve)

This is the signal generated by the CPU board (pin 6-3 of connector CN1) for controlling the resistance. It is a PFM signal, i.e. a square wave signal with variable frequency. The logic of this control causes the frequency to increase with increasing resistance. This signal enters the alternator interface board (pin 6-3 of connector CN1), and is converted in analog signal and sent to the alternator (pin 4-5 of connector CN2 on the alternator interface board) to supply its rotor via the brushes.

• Voltage across the resistor (Vr)

This is the dc voltage which the alternator dissipates on the resistor: the higher the excitation signal, the higher the dissipated voltage. This signal provides an effective measure of the electrical power generated by the alternator. This signal reaches the alternator interface board (pin 3-2 of connector CN2), where it is read and used as a feedback signal by the alternator interface board to adjust the excitation.

• RPM Signal

This is the speed signal output by the alternator. It enters the alternator interface board (pin 1-5 of connector CN2) and is a square wave which varies from –1 Vdc to a maximum value dependent on the training speed, as illustrated in the figure below:

The signal is cleaned and level-converted before being sent from the alternator interface board (pins 5-3 of connector CN1) to the CPU board (pins 5-3 of connector CN1) as a square wave which varies between 0 and 5 Vdc, as illustrated in the figure below:

11. APPENDIX

11.1. TECHNICAL NOTES ON CARDIO RECEIVERS

Technogym utilizes Polar technology for measuring the heart rate frequency of the person training on the machine. The Polar system consists of:

• a transmitter, worn by the person training on the machine, which uses 2 electrodes to detect the electrical activity of the heart and transmits the measured heart rate by sending an electromagnetic signal at a frequency of 5 KHz.

• a receiver, shown in the figure below, which consists of:

Figure 11.1-1

− an antenna a, designated the “coil”, which receives the signal from the transmitter strap

worn by the user.

− an integrated circuit b, designated the ASIC, which has the function of filtering the analog

signal and generating a pulse train corresponding to the received heart rate.

− two contacts c parallel to the coil, on which a 15 KOhm resistor is sometimes mounted.

The receiver is connected to the CPU board by means of 3 wires for:

− +5 Vdc power supply;

− Output signal (heart rate);

− ground.

The output is a digital signal that is normally at 5 Vdc and goes to 0 Vdc for a few msec when a heart beat is detected, as shown in the figure below.

Page 11.1

GLIDEX 600 XTPRO: Service & Maintenance Manual - rev. 1.1

There are 3 types of problems which can typically occur on the heart rate signal:

• interference caused by disturbances from sources of electromagnetic noise. These problems cause the heart rate signal to deviate from the rear value, typically making it higher;

• saturation caused by disturbances from sources of electromagnetic noise. In this case the receiver is no longer able to detect any heart rate signal;

• cross-talk similar to the interference problem, but is caused by reception of a signal from another strap, typically worn by users on adjacent machines if they are too close together.

The following paragraphs contain various suggestions which may be useful for improving the reception of the cardio signal.

11.1.1. TYPE OF ASIC

The cardio receivers can be equipped with 3 different types of ASIC models, identifiable by the code marked on the component: MAS, FTC or HRRE. These ASICs are characterized by different reception ranges and different levels of immunity to noise. Tests have determined that the maximum reception distances are as follows:

ASIC DISTANCE

(cm)

MAS 90

FTC 100

HRRE 85

As regards sensitivity to noise, the best ASIC is the HRRE model. This ASIC is also the one recommended by the manufacturer.

11.1.2. PRESENCE OF ELECTROMAGNETIC FIELDS

The receiver is sensitive to electromagnetic fields produced by the switching of LEDs, motor brushes, the commutation of power devices, monitors, neon lights, stereo equipment, etc., which can impair its operation. It has been found that such electromagnetic fields directly affect the analog part

Page 11.2

GLIDEX 600 XTPRO: Service & Maintenance Manual - rev. 1.1

of the receiver (detected by the coil) whereas they have no effect on digital components such as the CPU receiver connecting cable.

Electromagnetic interference can take different forms: on the one hand, the receiver may detect and hence generate spurious transients or periodic noise pulse, or on the other hand the receiver may become saturated. The presence of transients is generally accompanied by irregular blinking of the heart rate LED on the display, but does not affect the value shown which is processed by special SW filters. The presence of periodic noise pulse effect the heart rate signal. Saturation of the receiver, on the other hand, is a phenomenon which, depending on its intensity, can reduce the maximum reception distance until it becomes completely impossible to receive a signal.

In the presence of electromagnetic noise, use the frequency signal monitor shown in the schematic below to determine the presence, intensity and effect of the fields.

This circuit causes the LED to light for every heart beat and/or transient detected: in this way it is possible to determine whether there is electromagnetic noise, and identify its source.

The only effective solution in the presence of electromagnetic interference is to reduce the power of the noise source, using a trial and error method based principally on:

• Shielding the noise source.

• Increasing the distance between the noise source and the receiver, if necessary by changing the

position of the machines.

It is also possible to reduce the receiver’s ability to detect interference by:

• Changing the position of the receiver;

• Reducing the sensitivity of the receiver (see paragraph 11.1.3. );

• In some cases, it was found to be effective to screen the receiver inside a tagger box having a

thickness of 0.15 mm.

Please note that these are merely some possible suggestions, and that the effectiveness of the chosen solution must be verified in practice.

11.1.3. REDUCING RECEIVER SENSITIVITY

It is possible to diminish the receiver’s sensitivity in order to reduce its range of reception. This solution is recommended in the following cases:

• presence of electromagnetic fields which interfere with reception or saturate the receiver;

• problems due to interaction between the receiver on one machine and the signal transmitted by a

user training on another machine that is too close and cannot be moved farther away.

Page 11.3

GLIDEX 600 XTPRO: Service & Maintenance Manual - rev. 1.1

Sensitivity is reduced by soldering a resistor in parallel with the coil. Normally, the receiver already has a 15 KOhm resistor mounted in parallel with the coil, however it is advisable to check for its presence.

The following table shows the nominal values of reception distance based on the value of the resistor soldered on the coil:

RESISTANCE

(Ohm)

DISTANCE

(cm)

15K 89 13K 88 11K 87 9K1 85 6K8 84 5K1 81

3K 74 2K 69 1K 57

Please note that these are only nominal values. The actual reduction in sensitivity must be verified experimentally, taking great care not to excessively reduce the reception distance.

WARNING: if there is already a 15 KOhm resistor mounted in parallel with the coil,

note that adding another resistor in parallel will produce a total resistance value equivalent to the parallel combination of the added resistor and the existing 15 KOhm resistor.

11.1.4. MECHANICAL VIBRATIONS

Mechanical vibrations may cause slight shifting of the coil, giving rise to transient impulses. If these transients occur only occasionally they can be easily filtered by SW. However, if the mechanical vibrations are periodic, they can produce periodic pulses which may be interpreted as correct heart rate values.

To eliminate or reduce the effects of vibration, house the receiver between the foam pads in such a way that any vibrations are correctly damped.

11.1.5. POSITION OF THE RECEIVER

Carefully position the receiver according to the specifications below:

• the coil must be directed toward the user;

• the coil must be positioned well away (even a few centimeters) from the LEDs;

• the cable must be folded immediately after the connection on the receiver, so that it does not

pass near the coil;

• the receiver must be directed in such a way that its axis of reception is parallel to that of the transmitter, as shown in the figure below:

Page 11.4

GLIDEX 600 XTPRO: Service & Maintenance Manual - rev. 1.1

Figure 11.1-2

Please note that even small departures from the above specifications may considerably impair the accuracy of reception.

The optimal configuration is therefore that shown in the figure below:

Figure 11.1-3

11.1.6. ROUTING OF CABLES

Particular care must be taken in the routing of cables to prevent interference with the receiver coil.

Figure 11.1-4

Page 11.5

GLIDEX 600 XTPRO: Service & Maintenance Manual - rev. 1.1

11.2. PERSONAL CODED DEVICE

The machine can be equipped with a new heart rate receiver based on the PERSONAL CODED DEVICE technology developed exclusively by Technogym in conjunction with POLAR.

Thanks to a special receiver installed on the machine, and using a new “coded” chest strap, the machine receives only the heart rate signal from its own user. This makes it possible to eliminate the cross-talk problems, because each machine is selectively tuned into the heart rate signal transmitted by its user. This new feature translates into a considerable advantage for the health club owner: with the PCD system, it will now be possible to install cardio machines closer together, thereby fitting a greater number of machines into a given floor space area.

This technology is an evolution of the Polar Coded technology, with which it is fully

compatible. The PCD system differs from Polar’s standard coded technology because it incorporates certain features which ensure a more accurate and precise reception of the heart rate signal.

11.2.1. OPERATING MODES

The new system is based on the fact that the coded strap transmits the user’s heart rate signal accompanied by a special transmitter identification code. In fact, when the user puts on a coded strap, the strap randomly selects one of 28 available codes and starts to transmit using that code. The transmitted signal is shown in the figure below:

It should be noted that:

• The transmitter sends the measured heart rate together with another 2 pulses which represent the coding.

• The 2 coding pulses are very close together (20 msec) and separated from the heart rate pulse by a value T proportional to the transmission code, according to the table below:

Page 11.6

GLIDEX 600 XTPRO: Service & Maintenance Manual - rev. 1.1

Code T (msec)

1 35 2 40 3 45 4 50

.. ..

27 165 28 170

At the start of the training session, the coded receiver first of all seeks to detect a coded signal for a maximum of 10 seconds. This is done in reduced sensitivity mode to avoid receiving a signal from users on adjacent machines. If no coded signal is found, the receiver searches for a non-coded signal and functions in the traditional manner.

Consequently:

• If the user wears a “coded” strap and trains on a machine equipped with a Coded

receiver: the machine tunes into the user’s heart rate signal and operates in “coded” mode.

Synchronization time 3 - 7 seconds maximum.

• If the user wears a “standard” strap and trains on machine equipped with a Coded

receiver: the machine receives the user’s heart rate signal, but does not operate in “coded”

mode. Synchronization time 10 - 15 seconds maximum.

If the machines are installed extremely close together, there may be interference

problems in reading the user’s heart rate signal, as on traditional machines.

• If the user wears a “coded” strap and trains on a machine equipped with a “standard”

receiver: the machine receives the user’s heart rate signal, but does not operate in “coded”

mode. Synchronization time 3 - 7 seconds maximum.

• If the user wears a “standard” strap and trains on a machine equipped with a “standard”

receiver: this is the old operating mode of the machines.

WARNING: please note that the PCD system is based on the existing technology, with

the addition of the code signal. Therefore, this system can resolve problems of interference in reading the user’s heart rate but not those relating to saturation of the receiver in environments with very high levels of electromagnetic disturbance.
