CYBEX 770T Service Manual page 103

Error 19: Drive Enable Line is open
Cause:
The Drive is reporting the enable line (used for E-Stop) is open by clearing bit 4 of the status byte, when
the MCC is not sensing the key is out.
Service:
Intermittent connection in the console cable is the most likely suspect.
• Inspect each connection in this cable for loose terminals, unseated connectors, or pinched or abraded
wires.
• Power outages are also suspect, either at the utility or anywhere from the panel to the treadmill (power
cord, treadmill's inlet or power switch, floor/wall outlet, etc.)
• If these are in good shape, monitoring the power over a week's time may prove beneficial.
• If the available power is not the issue, the drive itself or related cabling should be inspected and/or
replaced.
