ROUBLESHOOTING
Another source of this problem could be excessive friction between
the deck and belt, usually caused by a lack of routine belt/deck
cleaning (see Chapter 5), or by a worn deck.
A third cause for this code could be a defective choke or a poor
connection at the choke assembly.
Last, the failure of an electronic component in the relay box or loss
of magnetism in the drive motor permanent magnet could also
generate this error message.
ERR 3: LOSS OF SPEED SIGNAL
This error message usually occurs after the treadmill has started
and indicates that the computer in the digital display control panel
is not receiving a motor speed signal from the speed sensor. The
causes for this error are similar to those listed for Error 1.
ERR 4: NO FREQUENCY LOCK
This error code can occur when the treadmill is powered on by
turning the main ON/OFF switch to the ON position and the
treadmill is unable to identify the frequency of the supply voltage.
The cause of this error can usually be attributed to noise or
“interference” from the power line. An electrical device with a high
speed motor, such as a vacuum, blender, or power saw, on a local
power line can sometimes cause this error. If this error occurs,
check to make sure the treadmill is installed on a dedicated line
and re-cycle the power to the machine by switching the main
ON/OFF power switch to “OFF” for 5 seconds and then switching it
back “ON.” If the problem persists, contact CYBEX or your local
CYBEX dealer.
ERR 5: ELEVATION ERROR
This error code indicates a problem with the elevation control
circuitry. It can occur if the treadmill recognizes a discrepancy in
the actual elevation grade vs. the grade set at the control panel. If
the actual elevation grade does not reach the set grade within 60
seconds, this error code will be saved in the error log.
A defect may be present in the elevation potentiometer, the
elevation wiring or other areas of the circuit.
If either of these conditions exist, call your local CYBEX dealer or
CYBEX customer service. An authorized CYBEX trained technician
can usually detect the source of the problem with a service visit.
ERR 6: OVERSPEED
This error code indicates a problem with the speed control circuitry.
It can occur if the treadmill recognizes a discrepancy in the actual
belt speed vs. the speed set at the control panel. If the actual
speed of the belt is 1 mph (1.6 kph) over the set speed for 0.2
seconds or 2 mph (3.2 kph) below the set speed for 2 seconds, this
error code will be displayed.
