Procedure 2.1 - Error Codes and Lower PCA Indicators
Error Codes:
The error codes used by the 9.23 and 9.27 treadmills do not conform to Precor
standardized error codes and are unique to these models. The 9.23, 9.27 error codes
are listed and defined below.
LS
- This error is displayed in the display’s
TIME
window when the drive motor speed signal is
not received from the speed sensor for eight consecutive seconds. When the
LS
error
occurs, all drive motor and lift motor motion is halted and the display is blanked except
for the error display.
Err
- This error is displayed in the display’s
TIME
window when the EEPROM is damaged or
unable to retrieve or store data. When the
Err
error occurs, all drive motor and lift motor
motion is halted and the display is blanked except for the error display.
E2
- This error is displayed in the display’s
TIME
window indicating an incline problem. This error
will occur if the incline is unable to move or if the incline position potentiometer in not
functioning. When the
E2
error occurs, all drive motor and lift motor motion is halted and
the display is blanked except for the error display.
E4
- This error is displayed in the display’s
TIME
window indicating an incomplete upper PCA to
lower PCA initialization has occurred. See Procedure 2.3. When the
E4
error occurs, all
drive motor and lift motor motion is halted and the display is blanked except for the error
display.
Lower PCA Indicators:
The lower PCA is furnished with seven LED indicators. Their names and
functions are listed below.
Power
- The
POWER
LED should illuminate when the treadmill is powered “on”. The
POWER
LED is in the 12 Vdc power supply and indicates the input to the power supply is
receiving voltage.
UP
- The
UP
LED should illuminate when the incline is operating in the upward direction. The
UP
LED indicates that operating voltage has been applied to the incline up relay.
DOWN
- The
DOWN
LED should illuminate when the incline is operating in the downward
direction. The
DOWN
LED indicates that operating voltage has been applied to the
incline down relay.
PWM
- The
PWM
LED should illuminate whenever the drive motor is in motion. The
PWM
LED
indicates that the PWM drive signal is being applied to the drive motor power controller
circuit.
