Procedure 2.1 - Accessing the Diagnostic Program
(917si only)
The keys on the display are hypothetically numbered for 1 to 7 from left to right. Therefore,
INCLINE
▲ would be key 1, INCLINE ▼ would be key 2, etc.
Placing the unit in the diagnostic mode causes the software to perform the following operations:
a. Test the LED’s mounted on the upper PCA;
b. Provide the option of calibrating the lift system;
c. Display the drive motor power bits;
d. Test the keyboard;
e. Display and test the heart rate function;
1. Plug the power cord into the wall outlet, then turn on the treadmill with the circuit breaker.
2. Press keys RESET,5,1,7,6,5,7,6,1, sequentially.
3. All of the LED’s on the display will light up. Any LED segment that is not lit is defective.
Press the SELECT key to continue.
4. After the LED test, the electronic console displays the potentiometer increment number.
5. Verify that the running bed inclines and declines as the INCLINE
▲ or INCLINE ▼ keys are
pressed.
6. When the potentiometer increment number is displayed on the electronic console, the
potentiometer increment number will track the incline as it is operated. Press the SELECT
key to continue.
7. The power bit number will be displayed.
Note:
When the running belt is started, the number of power bits will be displayed. Power bits represent
the amount of power applied to the drive motor. Power bits are the product of selected speed and
applied load.
8. Press the SPEED ▲ or SPEED ▼ key. Verify that the power bits number increments and
decrements as the SPEED keys are pressed. The Select key will toggle the display
between the power bit reading and a mile (or kilometer) per hour reading.
9. Press the STOP key to exit the power bits mode.
