ERROR MESSAGES
NOVRAM - DGA3J: Px values "Init"(flashes on board and beeps) on power up. Px values stored in NOVRAM are outside valid ranges or the checksum is invalid. The system checks for a valid P6 configuration. It writes the default values with respect to P6, if valid. If not, it writes default values to the NOVRAM based on a "4" (T9350) configuration. No user interface necessary - occurs on power up. P6 value may need to be recalibrated depending on model: This console will reconfigure itself for a T9350.
NOVRAM - DGA3J: User program values "UCLr" (flashes on board and beeps) on power up. Time, speed, and elevation values stored in NOVRAM are outside valid ranges or the checksum is invalid. The system clears the user program values. No user interface necessary - occurs on power up. If "init" occurs, "UCLr" also occurs afterwards, but not vice versa.
NOVRAM - DGB1J: Same NOVRAM error as the DGA3J except the treadmill will reconfigure itself for a T9600HRT.
P6 value may need to be recalibrated depending on the model: NOVRAM - DGB1J: Same NOVRAM error as the DGA3J
ERROR MESSAGE CODES
E2* T9200 & T9250 only. E2 is the only error programmed into the software. There are no E2 errors for T9300
through T9700 treadmills.
E4 Incline position is outside the tolerances
E5 Elevation stall condition
E6 Signal from elevation is lost
E7 Belt is accelerating too fast
*E2: Solution (T9200 & T9250 are the only treadmills with this error)
E2 is the only error message programmed into the software for the T9200 and T9250. Trouble shooting an E2 on the T9200 and T9250 can be difficult. Use information provided in all the Error Solutions for assistance in pin pointing the problem.
1. If the elevation motor is jammed. (Humming and too warm)
• Remove elevation motor tub from elevation rack
• Unjam or replace elevation motor
• Check all connections
• Test/change large data cable (use large data cable information provided in the data cable portion of this guide)
• Make sure the tube end of the elevation motor is in the correct location on the worm gear
• Make sure the P4 value in calibrations is correct before reinstalling the tube end of the elevation motor to the elevation rack
• Auto Calibrate the treadmill

E4: Solution
1. Check power to the treadmill, as insufficient voltage to the treadmill can cause this error to reoccur. Check the power socket that the tread is plugged into. Eliminate any extension cords or surge protectors (plug the tread directly into a functional power source). Make sure the circuit is not overloaded. Make sure the circuit is NON-GFI.
2. Calibrate
3. If calibrations do not hold, replace upper console.

E7: Solution
1. Certain lower boards have an LED that flashes when the magnet on the roller passes the sensor. Adjust sensor position if LED does not flash. See lower board basic troubleshooting for lower boards with the LED.
2. Unplug RPM sensor at the lower board. Treadmill will operate without sensor but cannot Auto-calibrate.
3. Replace RPM sensor
MAINTENANCE MESSAGES
The T9600 and T9700 have maintenance messages programmed into the software (see the DGB1J Engineering Guide). These messages indicate that the treadmill has reached the recommended number of hours of use since the last lubrication (LUBE HRS) or the recommended distance since the last cleaning (CLEAN) or the motor brushes (BRUSH) have been replaced. This is NOT an error message and the treadmill can continue to be used, providing the user arranges for the appropriate service. The purpose of the maintenance messages is to assist the user in observing a maintenance schedule that will help provide the most reliable service for their treadmill.
