Service manual Valiant treadmill V1.00
Intended Use
A Lode treadmill is a diagnostic tool intended to be used as a stress test device in a medical
environment. The main goal of the use of a Lode treadmill is to create reproducible stress
tests. The following parameters can be measured:
• Speed (km/h or Miles/h)
• Time (minutes and seconds)
• Distance (km Miles Meters)
• Optional: Heart rate (beats per minute)
• Grade (%)
In combination with other diagnostic tools, like ECG or pulmonary function equipment, other
important physiological data can be obtained, allowing a physician to evaluate a test subject’s
physical status.
A Lode treadmill is designed both for manual operation and control by external ECG-,
pulmonary equipment. In combination with optional software, the ergometer can also be
controlled by a PC.
The Lode treadmill has to be operated under the supervision of well-trained medical specialists,
like cardiologists, pulmonologists and physiotherapists. The ultimate judgment whether a test
subject should undertake a stress test with an ergometer and which protocols should be used
must be made by the responsible medical specialist, based on the limitations of each
individual, the medical history and all other applicable circumstances. Neither Lode BV nor her
distributors take any responsibility for the final use of its equipment.
Contra Indication
The Lode treadmills are to be operated by classified personnel only. As stated in the
intended use, the Lode treadmills are intended to be used in a medical environment. During the
intended use the test subject will deliver energy. Application of the wrong dosis of energy
could lead to permanent damage of the test subject’s health.
Maintenance
The Lode treadmills should be calibrated once a year. In case any damage is observed of the
Lode treadmill. Lode B.V. or her representative should be informed in order to execute the
necessary repair(s). Service of the Lode treadmills is restricted to factory-trained personnel
only.
Precautions
Caution: This device should only be sold by, or on the order of authorized persons.
Caution: Not suitable for use in the presence of flammable anaesthetics.
Possible hazards
Using the Lode treadmills according to intended use, contra indications, maintenance,
precaution and common sense stated above may not eliminate all hazards. Possible residual
hazards could be: wrong installation, wrong use, wrong dose, wrong interpretation of
readings, mechanical breakdown of parts, software failure.

3.1 Replacement controller board
1. Open the control unit by removing the four Allen screws at the back of the control unit
(fig 1)
2. Remove the two black side covers. (fig 2 and fig 3)
3. Take the control board out by sliding the board from the clips (fig 4)
4. Remove the connectors from the board (fig 5, fig 6 , fig 7 and fig 8)
5. Take out the cable clamb from the flatcable (fig 9)
6. Slide out the control board (fig 10)
7. Remove the screw (M8) that holds the control panel (fig 11)
8. Take off the aluminium housing (fig 12)
9. If you need to replace the 25-wire ribbon cable that runs through the chassis of the
handgrip, cut-off the connector at one end and pull the ribbon cable out.
10. To pull the new cable through the chassis use a fishing tape and slide it through the
pipe first (fig 13)
11. Use a pair of tweezers to grab the end of the fishing tape(fig 14)
12. Pull out the fishing tape ( fig 15)
13. Connect the new ribbon cable with tape to the fishing tape (fig 16)
14. Guide the cable through the hole while you pull the fishing tape ( fig 17 and fig 18)
15. Push the cable into the control unit (fig 19)
16. Install the control unit in reversed order as described above.
17. The connector on the 26 wire flat cable should be connected with the marked cable
(red/bleu) at the side of the connector with the square solder island. Best visible at the
not component side of the circuit board.
18. Be careful the ribbon cable can be connected in two ways. See (fig 20) for the correct
connection.
19. Do not forget to place the dummy plug in the control unit at the treadmill, which has
to be used when there is no extra emergency stop installed at the handle bar (fig 21
and fig 22)
20. If the Valiant has been controlled by an external device do not forget to set the correct
RS232 protocol and baudrate for the communication.
