Cybex treadmill – Cybex 600T - How to enter to Test mode – Treadmill error codes – How to adjust the speed sensor – treadmill repair and service

Cybex 600

Test Mode
To enter Test Mode press and hold down any key on the display and turn the power switch on (I). "TEST" and "rx.Xx" will now be displayed on the main screen to show software revision.
NOTE: If Test Mode occurs without holding any keys, a key may be stuck closed. If "KEY" and a number is displayed you can determine which key is stuck closed by referring to the diagram below. You may need to replace the upper and/or lower display overlay depending on which key is stuck closed.
LED Functions
Endurance LED - Brush sense status. Off =OK, On =sense activated
Sport LED - E-stop status. Off =relay closed, On = relay open
Hills LED - Speed sense
Heart LED - Heart rate signal
Manual LED - Salutron (on if present, blinking off)
Age LED - Receive CSAFE data
Target LED - Transmit CSAFE data
Incline LED -  0% switch (off =<0%, on >0%)
Treadmill Error Codes
A processor upset can cause any of bAdO
through 4. If the chip is misprogrammed the display typically won It run at all. Try turning the treadmill to the off (0) position and back on (I). If bAdO through 4 still occurs you may need to replace the upper display board.
Born - uninitialized EEPROM (loads defaults & enters test mode). Only displayed on initial power up of a new display board
bAdO - EPROM checksum failure
bAd1 - Faulty microprocessor reset
bAd2 - Internal RAM error
bAd3 - Watchdog fault type 1
bAd4 - Watchdog fauIt type 2
Brush - Motor brush wear. "BRUSH" scrolls while in Dormant Mode. Err9 will occur after 100 miles (160 kilometers) and the treadmill will be disabled.
Err1 - Belt didn't start (or no speed sense). See Speed Sensor Adjustment below.
Err2 - Underspeed (2 mph for 2 seconds without correction in process)
Err3 - Speed sense lost. See Speed Sensor Adjustment below.
ErrS - No 0 switch sense within timed limits. This is declared when the timed elevation reaches -2% without tripping the index.
Err6 - Overspeed (1 mph for 1 second or 2 mph for 2 seconds without correction)
Err? - EEPROM error (memory lost, loads new defaults, enters test mode)
Err8 - Sudden acceleration or deceleration of belt
Err9 - Brush wear too low. Indicator has been activated for over 100 miles.
ErrE - 0% always on (or switch disconnected or wired backwards). This means that timed elevation has gone up 2% and the index is still sensed.
Speed Sensor Adjustment
Tools Required
Phillips head screwdriver
1. Turn the power off.
A. Turn
the main power switch on the front panel to the off (0) position. (It is labeled I/O).
B. Unplug the treadmill from the power outlet.
2. Remove the motor cover.
A. Remove the two Phillips head screws that fasten the motor cover to the frame.
B. Lift the cover from the front and remove it from the treadmill. Set the cover and screws aside.
3. Adjust the speed sensor gap.
A. Loosen the Phillips head screw. Adjust the gap between the speed sensor and the flywheel should be between 1/4 - 5/16" (.635 -
.795 cm).
B. Tighten the Phillips head screw.
4. Attach the motor cover.
A. Place rear of the motor cover in the rear guide holes
B. Lower the front end of the motor cover and install the two Phillips head screws.
5. Turn power on (I) and test for any speed errors.
6. If any errors occur, readjust the speed sensor.

Running Belt Maintenance
The running belt and deck should be checked periodically for any excessive wear. The belt may need minor adjustments. Use the following section to help keep your BOOT operating properly.
Checking the Belt and Deck Surfaces -In an effort to make sure that the running belt operates properly, visually inspect the belt on a weekly basis to make sure that there are no tears or fraying in the belt material.
To inspect the edges of the belt, it is necessary to remove the plastic side rails. Follow these steps:
1. Turn the power off.
A. Turn the main power switch on the front panel to the off (0) position.
B. Unplug the treadmill from the power outlet.
WARNING: When removing or installing the side rails be sure to wear work gloves to protect against any sharp edges.
2. Remove the plastic end caps and side rails.
A. Remove the Phillips head screws that fasten each of the plastic end caps in place and set aside. 
B. Grab the side rail and firmly slide it out towards the back of the treadmill.
