Error Codes
Cybex provides error code descriptions for your information. Cybex
recommends that these errors be addressed by a qualified service technician.
These codes notify you of a problem condition and errors which jeopardize
safety will shut the treadmill down. The codes also help to indicate the part of
the treadmill most likely to be causing the problem.
ERROR 1: No Speed Signal at Startup
ERROR 2: Excessive Current Draw
ERROR 3: Loss of Speed Signal
ERROR 50: Overspeed (stored as ERR 6)
ERROR 70: Loss of NOVRAM Information (stored as ERR 7)
If you have a problem that interrupts an important operational area of the
treadmill, you may see one of the above error codes displayed in the control
panel. If an Error Code is generated during operation, the treadmill's drive
motor will stop. In order to restart the treadmill, the Error Code must be cleared
by cycling the power to the machine by switching the ON/OFF switch to “OFF”
for five seconds and then switching it back “ON” again. Should a code
reappear soon after cycling off, then on again, report the problem to your
Cybex dealer, authorized Cybex service representative or directly to Cybex
Technical Support.
ERROR 1: No Speed Signal at Startup
This error code usually occurs only during start-up and indicates that the
computer in the control panel is not receiving any indication of motor speed.
To isolate the source of this problem, you need to determine whether the drive
motor tried to start up and did rotate or whether it never came on at all.
If the drive motor (and running belt) rotates, even if only for a second or so, the
error code usually indicates that the speed sensor is malfunctioning. The quick
way to check this is to remove the motor cover and the front panel to witness
the SPEED LED on the motor control board. If it blinks when the flywheel is
rotated by hand, the problem is most likely the console cable. After that,
suspect the lower board and then the display board. This signal can also be
seen on a diagnostic LED of the display board.

If the drive motor (and running belt) does not rotate at all, the problem is more difficult to
diagnose. First, suspect the power relay and check it by going into diagnostics, C18, and
press the v elevation button in conjunction with the SPEED + button. This will toggle the relay
on/off. You should be able to hear the relay toggle and note as well that the value in the
center window reads “1.” If it reads zero, the problem is most likely the console cable.
If none of these prove to be the problem, have a qualified service technician check the wiring
for wear or abrasion and also inspect the motor brushes. Any arcing, pitting or burning of the
brushes, or a brush that is less than .438” (7/16"/11.13mm) indicates the need for brush
replacement. The tightness of the brush cap and brush holder mount in the drive motor
housing should also be checked. NOTE: There are two lower board fuses which allow power
to the display and to the motor drives. The upper display is not likely to light up at all if one or
both of the fuses need to be replaced. Have a qualified service technician replace these only
with equivalent value fuses.
ERROR 2: EXCESSIVE CURRENT DRAW
This error code is generated by exceeding the current limit of the motor drive system for two
seconds. The error is generated to help prolong the life of the treadmill and alert the owner
to a potentially damaging situation. Most common occurrences of this are high belt/deck
friction due to wear or contamination, a worn motor, or a breakdown of the choke. Problems
in the drive motor brush area, such as worn, pitted or arcing motor brushes, a loose drive
motor brush cap, or a loose drive motor brush holder can also cause this error code to
be generated.
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 motor control or loss of magnetism in the
drive motor permanent magnet could also generate this error code.
ERROR 3: LOSS OF SPEED SIGNAL
This error code occurs after the treadmill has successfully started and indicates that the computer in the display control panel has lost the motor speed signal from the speed sensor. The
causes for this error are similar to those listed for Error 1.
ERROR 50: OVERSPEED
This error code indicates a problem with the speed control circuitry. This error is stored as
ERROR 6 but displayed as ERROR 50.
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.
Cybex 710T Treadmill Owner’s Manual
Page 7-12
If the speed attempts to increase, it may be because of a defect in the power
supply circuitry to the drive motor, the speed sensor, or the filter capacitor.
If the speed attempts to decrease, it is most often because a person is pushing
on the belt. Or it may be because of a defect in the drive motor, the speed
sensor, or a worn running deck.
If either of these conditions exist, call your local Cybex dealer, authorized
Cybex service representative or directly to Cybex Technical Support. An
authorized Cybex technician can usually detect the source of the problem with
a service visit.
Error 70: LOSS OF NOVRAM INFORMATION
This error code indicates a problem with the nonvolatile random access
memory (NOVRAM) contents. This chip is located on the DDM. Its contents
may have become lost or destroyed. Among other data, this chip holds the
accumulated miles and speed information. You can reset the NOVRAM by
turning the treadmill off and then on again, but you may lose all the
accumulated data. Should the problem recur, you need to replace the
NOVRAM chip.
Diagnostic Tests
These tests display status information about the treadmill to help you isolate
the cause of a problem or to monitor accumulated usage data. Some of the
tests also give quantitative information (such as motor current readings and
elevation encoder counts) to help you further evaluate the machine's condition.
