SportsArt - 8100 Elliptical Trainer - Incline Calibration Guide
Introduction
A
n incline motor, like those in treadmills, makes the 8100 ramp up and down. Incline calibration is required when
the incline gets stuck and won’t operate. If the incline set operates but clicks, replace a gear in the incline motor
box or replace the whole incline set.
Incline Calibration Instructions
Calibration of an 8100 incline set is just like the calibration of a treadmill incline set. There are two parts -- one
mechanical and one electronic.
Mechanical Calibration
In mechanical calibration, we set the incline motor to the mechanical 0% position.
1. Take off covers by removing screws as shown in Fig. 1 below.

2. Remove the incline motor set as shown in Figure 2. First, remove the pins that hold the incline motor in place.
Then pull out the motor.
3. Remove the VR box from the incline motor as shown in Figure 3.
4. Adjust the incline motor set mechanically as shown in Figure 4. Twist the thin pipe so that its red line is even
with the end of the thick pipe. This completes calibration to the mechanical 0% position.
Figure 2. Remove the motor. Figure 3. Remove the VR box. Figure 4. Calibrate mechanically.

Electronic Calibration
In electronic calibration, we set the incline VR (variable resistor) to the 0% position.
5. Connect the VR wires as shown in Figure 5 by linking like-colored wires.
6. Set your voltmeter to VDC. Probe into the blue and green VR wires while keeping them connected to the drive
board and VR.
7. Turn on unit power. Turn the VR gear shown in Figure 6 to set the voltage at 1.20 VDC – the electronic 0%
setting. This completes electronic calibration of the VR set.
Reassemble the Incline Set
8. Place the VR box on the incline motor as shown in Figure 7. Tighten the screws.

9. Reinstall the incline motor as shown in Figure 8.
Test Incline Operation
10. Press display RAMP<▲> key until the RAMP window shows 10. The incline should operate to the highest
point.
11. Press the display RAMP<▼> key until the RAMP window shows 0. The incline should operate to the
lowest point. (The red line on the thin pipe should show above the end of the thick pipe on the incline motor).
12. During incline operation, inspect whether the drive board ERR LED lights. If the unit has been calibrated
properly but the ERR LED still lights and wires are secure, the VR is malfunctioning. Replace the VR box.
13. If the motor jams or fails to move when there is power to it from the drive board, replace the incline motor set.
Figure 8. Reinstall the motor.
