Error 4: Upper Display Communications issue
Cause:
Main computer board is receiving incomplete, erroneous, or no information from the upper display that
occurred even after three re-tries. The upper display is not required for the treadmill to function safely,
so this is a stored error only. If and when the product is in Dormant, the main computer board will attempt
to cycle power or reset the Upper Display system.
Service: LED Console
If this occurs in Dormant, the cause is likely a software defect or power fluctuation. If this occurs mostly
in active mode, it could be due to ESD events or increased data traffic.
• Check internal cabling between the MCC and Display board.
• Ensure there are no cracks or openings in the upper display's console decal or membranes
• Verify no moisture intrusion has compromised the MCC, display or cabling.
Service: EPEM (Embedded PEM or E3) Consoles
If this occurs in Dormant, the cause is likely a software defect or power fluctuation. If this occurs mostly
in active mode, it could be due to ESD events or increased data traffic.
• Check internal cabling between the MCC and EPEM.
• Ensure there are no cracks or openings in the upper display's console decal or membranes
• Verify no moisture intrusion has compromised the MCC, EPEM or cabling.
