The tests grouped under this section conduct checks on the machine’s operation in a fully automatic
manner. After selecting the desired test using the
+

the test and then await the result. Press

below.
6.1.1.1.
I2C Devices Test
The I2C Devices test checks the communication following the 32K and 256K. The test can have
outcomes:
•
“Test Successful, press Enter to continue”: Signifies that the transmission and reception of
data packets between the I2C devices and the display board was completed successfully.
•
“EEPROM Error, press Enter to continue”: Signifies that the display board is having
problems communicating with its memories.
6.1.1.2.
Up-Down Test
The Up-Down test checks whether the number of pulses output by the encoder corresponds to the
values of the Up-Down table stored in the low kit. During the test, the machine incline is moved
from 0 to 15% (
for 700 models
) and from 0 to 18% (
for 900 models
) and then back to 0. Each
incline position is converted into a number of pulses and compared with the value in the Up-Down
table.
Two messages appear during the test:
•
“Incline =15%”: This message appears during the upward movement, when the machine
incline reaches 15%.
•
“Incline =3%”: This message appears during the downward movement, when the machine
incline reaches 3%.
The test can have two outcomes:
•
“DC Error (Up/Down), press Enter to continue”: The message indicates that the values do not
correspond. The specific message (Up or Down) indicates whether the error occurred during
the upward (Up) or downward (Down) movement of the test.
•
“Test Successful, press Enter to continue”: This message indicates that the test was completed
without errors.
