CHAPTER 2: Troubleshooting
2.4.1 TROUBLESHOOTING –CONSOLE DOES NOT LIGHT UP
SOLUTION:
1. The outlet the machine is plugged into is functional.
2. The correct power cord is being used. Only use the power cord included or provided by Customer
Tech Support.
3. The power cord is not pinched or damaged and is properly plugged into the outlet and the machine.
4. Remove the console and check if the console cable has good connected with the console.
Test console cable for 12VDC between pin1 & pin8. If power and connection is good, replace console.
5. Check to see if the console upper cable and console lower are connected well.
6. Remove the side cover and check to see if the cable is connected well.
7. For E30
7.1 Check to see if using correct adaptor: output 12VDC 2A.
7.2Remove the ECB to console cable (see Page7 figure 1). Use multi-meter to check the ECB CN3
Pin1/Pin2 (Positive) and Pin 8 (GND) if cannot see voltage +12 VDC. Install new ECB.

For E50
7.3. Unplug the console cable from the LCB (see Page12 figure-2). Use multi-meter to check the
LCB JP1 Pin1 (Positive) and Pin 8 (Negative) to see if voltage is +12 VDC.
7.4 If a cannot see +12VDC, connect the LCB to Console cable. If still cannot see light on the screen,
the console is damage, install new console..

CHAPTER 3: Troubleshooting
2.4.2 TROUBLESHOOTING – SPEED DOES NOT DISPLAY
SOLUTION:
For E30
1. Unplug power adaptor, remove the console, and check that all connections to the console are secure
and not damaged or pinched.
2. Remove the side cover and check to see if the sensor wire (CN01) is connected well and not damaged.
(Fig.1)
3. Check to see if one corner of the sensor is aligned with the magnet and ensure that the distance is less
than 5mm.(Fig-1)
4. Test speed sensor with multi-meter in Ohms on Pin1 & Pin2. While passing by magnet, take continuity
readings, open and close, and see if console can display speed.
5. Install new ECB Page7 (Fig-1) to see if console can display speed.
If still cannot display speed value, replace the console.
For E50
1. Unplug power cord, remove the console, and check that all connections to the console are secure and
not damaged or pinched.
2. Remove the side cover and check to see if the sensor wire (LCB JP02) is connected well.-(fig-2)
3. Check to see if one corner of the sensor is aligned with the magnet and ensure that the distance is
less than 5mm. (Fig-3)
5. Install new LCB Page7 (Fig-2) to see if console can display speed value. If still cannot display speed
value, replace the console.

CHAPTER 3: Troubleshooting
2.4.3 TROUBLESHOOTING- HEART RATE ISSUES
SOLUTION:
a. Re-center the HR strap on user's chest, strap must have some moisture for good connection.
b. Replace the battery in the HR strap.
c. Wet the user's hand, and then reestablish contact with the HR grip.
d. Replace new HR grip if console can display proper HR rate.
With a multi-meter set for DC voltage, place one terminal on each of the HR grip plates. The HR
Grip should give a voltage reading of between 0.5 and 2.0VDC. If the voltage is not between 0.5
And 2.0VDC, remove the screws holding the HR grip together and check the connection of the
HR grip wiring.
e. Check a-d. If still the HR still does not display, install new console.

CHAPTER 3: Troubleshooting
2.4.4 TROUBLESHOOTING- QUICK KEY ISSUES
SOLUTION:
Install new keypad and overlay.

13
CHAPTER 3: Troubleshooting
2.4.5 TROUBLESHOOTING- NOISE ISSUES
SOLUTION:
1. Make sure that the console mast is tightly attached to the frame.
2. Make sure that the front stabilizer and rear stabilizer are tightly attached to the
frame.
3. Make sure that the pedal arms are tight.
4. Make sure that the handlebars are tight.

14
CHAPTER 3: Troubleshooting
2.4.6 TROUBLESHOOTING- NO RESISTANCE OR INCORRECT RESISTANCE
SOLUTION:
1. Check if the console shows RPM value. If not, refer to solution for “SPEED DOES NOT DISPLAY”.
2. Turn on the console and check the ECB motor. In resistance level 1, the head of steel rope points
toward directs to top right side (around 45 degree). If the head of cable points toward the bottom left
side, the resistance will be reversed. Adjust the head of steel rope to the correct position.(Fig -1)
Fig-1
3.Press key up “ ↑” to increase the resistance.
A) If ECB motor cannot move but the console screen shows change, the ECB motor or console
cable may be defective. Be sure that the console cable is inserted in ECB motor. Use a
multi-meter to measure the ECB CN3. Pin3 (POS) and Pin5&6 (GND) : normally it should be DC
6V. If no output, test the console cable. Install the console cable. If output is 6VDC, the ECB
motor is defective. Replace ECB.
B) If the ECB motor can move, the resistance can be adjusted. If the resistance is still too heavy,
check the gap (Fig-1) between the orange block and the bottom. It should be within 1-2 mm. If the
gap is bigger than 1-2 mm, the resistance will be heavier than normal. Adjust the cable to the
correct gap.
4.If all above conditions are met, and the resistance is still heavy, inside magnet is defective. Replace
the inside magnet as the last step.

15
For E50
Unplug the cable at J03 and be sure console cable is inserted in JP1 (Fig-1) .Use multi-meter set to DC
voltage to check the voltage of JP03 pin1& Pin2. If cannot measure any voltage, replace LCB. If you measure
any voltage replace console. If you can measure any voltage in JP03 but resistance still does not function,
test the ECB (Fig-2) .
