elevation potentiometer (it should be more than 225 when the treadmill is
completely elevated). The treadmill will elevate to the high limit switch. The top
display will then change to “0.0” which is the low grade set in the Factory Settings
Mode. The speed display will show “dn4”. The elevation display should be less
than 30 when the treadmill is completely lowered. The treadmill will descend to
the lower limit switch. The software will automatically create a scale based on
the difference in resistance of the potentiometer from the upper to the lower limit
switches.
When the elevation calibration is complete, the top display will show “ECAL” and
the speed display will show the lower grade limit and the elevation display will
show the upper grade limit (both in terms of the scale value). Press START and
the system will reboot, load data and resume normal operation.
I. Software Set Up After Upper PCB Replacement (Version
10.1-10.5)
1. Once upper display has been replaced, restore power to the treadmill and put
the emergency stop magnet in place. Make sure not to press any buttons
on the display while performing this step.
2. When the display has booted up, “-AC-“will be shown in the time window.
Press the ELEVATION UP or ELEVATION DOWN arrow once to display “-
DC-“in the time window. With “-DC-“displayed, press the START button.
ECAL” will appear in the time window.
3. Press the START button to begin ELEVATION CALIBRATION. The treadmill
will elevate to its highest point and will set a value. It will stay at the highest
point for approximately four (4) seconds. The treadmill will then descend to
its lowest point and retrieve a value. Once ECAL is completed, “ECAL” will
be shown in the time window, the lowest elevation value in the speed window,
and the highest elevation value in the elevation window.
4. Press START again. “ECAL PAS” will flash briefly and then the display will
reboot to show “SCALin the time window.
5. Make sure there is nothing on the treadmill belt. It will be moving at
high speed on this next step. In SPEED CALIBRATION mode, the target
speed appears in the speed window, while the actual speed appears in the
time window. The elevation window displays a default variable set by the
software on a 250-bit scale. Press the START button one (1) time to begin
SPEED CALIBRATION. The belt will start to run at a very rapid speed.
6. The target speed of “10.0” will appear in the speed window. Whatever the
actual speed is will appear in the time window. If the actual speed is more
than .30 mph faster than the target speed, turn the speed pot, labeled R56 on
the motor controller (lower PCB), counterclockwise until the range is found. If
the actual speed is lower than the target speed, turn the speed pot clockwise
until actual speed is between 10.00 and 10.30 mph. Once the speeds are
within range, press the START button.
