RUN MED: Service & Maintenance Manual - rev. 1.0
6.1.1. AUTOMATIC TESTS
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 + and – speed keys, press ENTER to initiate the
test and then await the result. Press ENTER again to continue, or press the CLEAR key for a few
seconds to return to the higher menu level. The various tests are described below.
6.1.1.1. I2C Device Test
The I2C Device test checks the communication following the 32K and 256K memories. The test
can have two outcomes:
• “Test Successful, press Enter to continue”: Signifies that data packets were successfully
transmitted and received toward the display board.
• “EEPROM Error, press Enter to continue”: Signifies that the display board has
communication problems with the memories.
6.1.1.2. UpDown Test
The UpDown test checks whether the number of pulses output by the encoder corresponds to the
values of the UpDown table stored in the low kit. During the test, the machine incline is moved
from 0 to 18% and then back to 0. Each incline position is converted into a number of pulses and
compared with the value in the UpDown 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.
6.1.1.3. Inverter Test
The inverter test checks the condition of the AT driver. The test can have two outcomes:
• “Test Successful, press Enter to continue”: This means that the test was completed
successfully and the inverter is not in an error condition.
• “Inverter Error, press Enter to continue”: This means that the test was not completed
successfully, i.e. that the serial link is inactive and/or the inverter is in an error condition.
6.1.1.4. LED Test
The LED test checks the functioning of the display by lighting all the LEDs in the matrix. It also
tests the buzzer, varying the frequency to produce different tones of sound.
The test does not produce a result message, so the user must visually check the outcome.
