In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

TENSIONING THE BELT PROCEDURE
Caution:
Over-tightening of the roller will severely shorten the life of the belt and may cause
further damage to other components.
Running Belt:
If when you plant your foot on the belt, you can feel a slipping sensation then the belt has stretched and is slipping across the rollers. This is a normal and common adjustment on a new treadmill. To eliminate this slipping, tension both the rear rollers Allen bolts 1/4 TURN as shown above. Try the treadmill again to check for slipping. Repeat if necessary, but NEVER TURN the roller bolts more than ¼ turn at a time.


Perfect Tension of Running Belt: 0.9 -1.1 lbs
Drive Belt:
If you have tensioned the running belt and are still experiencing a slipping, adjust the tension screw. Then try the treadmill again to check for slipping

DECK RE-WAXING PROCEDURE
Frequency: Every 1 month
Caution:
If deck is not to periodical add the waxing, between the deck and running belt will produce great friction make the deck and running belt to burn up and cut down the motor life .
Parts name: Silicon oil set
1. Loosen the tension bolts at both ends.
2. Pull the belt with your left hand and apply the silicon in the deck with your right hand. (The volume of silicon applied is about 40ml)
3. Tighten the tension bolts.
4. Start the treadmill. Step on the treadmill belt to walk the silicon in.
Adjust the belt tension if necessary.
5. With the clamp-on meter, measure the current draw of the motor. (Clamp on either the red or the black wire.) The current should be less than 15Amps for 110V model. (less than 7.5Amps for 220V model.)

LED INSTRUCTIONS
NORMAL OPERATION
1. LEDs 1, 2 and 3 Sequence back and forth to indicate the processor is on-line and operational.
2. LED 4 is used as a discrete/analog signal to the upper console.
3. LED 5 indicates system status/mode. Currently 3 modes are defined safe mode, stand-by mode and run mode. They are defined as follows:
a) Safe Mode - When the controllers safety relay is not energized and no error exists, LED 5 remains off.
b) Stand-by Mode - When the safety relay is engaged but the system is not outputting an active PWM to the motor and no error exists, LED 5 blinks off and on at a fast rate.
c) Run Mode - When the system outputs an active PWM Control signal to the motor and no error exists, LED 5 remains ON.

Step 1. Calibrate Elevation
Step 2. CORRECTIVE ACTION
1.Ensure correct signal is being sent to interface board (MCB) by pressing elevation up/down keys by observing elevation LED’s correctly corresponding to correct elevation keys pressed (please refer the 29 page) . If failure occurs for this step check console cable and then the interface board (MCB).
2.Check failed elevation motor, interface board, console cable with a known good console.
E2 – Elevation Out Of Range
Step 1. Calibrate Elevation
Step 2. CORRECTIVE ACTION
1.Check the failed system with a known good console cable. If fixed then
repair/replace the console cable.
2.Check the failed system with a known good elevation motor. If problem fixed then
repair/replace the elevation motor.
3.Check the failed system with a known good interface board. If problem fixed then
repair/replace the interface board (MCB).
4.Check the failed system with a known good console board with current software. If
the problem is fixed then repair/replace the console.
E3 – Elevation Stall
CORRECTIVE ACTION
1.Allow elevation motor to cool.
2.Check the failed system with a known good console cable. If fixed then
repair/replace the console cables.
3.Check the failed system with a known good elevation motor. If problem fixed then
repair/replace the elevation motor.
4.Check the failed system with a known good interface board (MCB). If problem
fixed then repair/replace the interface board (MCB).
5.Check the failed system with a known good console board with current software. If
the problem is fixed then repair/replace the console.
E5 – Over-speed Error
Step 1. AUTO CALIBRATION
Step 2 :
1.Record when parameter information with error (please refer the 25 page of P1 / P2 / P3 place) .
2.Remove Power!!! Carefully check all connections.
3.Check interface board (MCB) with the speed sensor ensure contact are correct and fix.
4. If AUTO CALIBRATION can't finish, please take speed sensor to be close to magnet and AUTO CALIBRATION again.
5.If repeat over speed errors occur remove the treadmill from service
E6 – Runaway Belt Error
OVERVIEW
If the actual belt speed is greater than the target speed by a limit and increasing then an E6 error is called. E6 errors flag errors that will result in the belt “running away” or not responding to input.
1.Remove Power!!! Carefully check all connections, interface board and the Reliance Motor controller setting to ensure all settings are correct.
2. Enter the engineer mode to SERVICE 5, press "START" key to clean "ERROR LOG" and refer the T5x Engineer mod parameter set SOP to confirm the machine parameter whether is correct.
3. AUTO CALIBRATION again.
4. If AUTO CALIBRATION can't finish, please take the speed sensor to be close to magnet and AUTO CALIBRATION again.
E7 – Speed Stall Error
OVERVIEW
If no belt movement is detected several seconds after commanding belt movement a speed
stall error (E7) is called.
Belt Drive Issues
Speed Feedback Issues
Speed Feedback Missing Issues
Calibration Issues
E9 – Speed Range Error
OVERVIEW
During normal run time operation the value stored during auto calibration is used to initially set the speed (e.g. target speed = 12 MPH, PWM ticks = Maximum PWM = 363). Once the speed stabilized the actual speed is monitored and if different than the target speed the PWM value is adjusted until the actual speed matches the target speed. If the PWM value is changed by more than the amount of ticks required to change 0.8 MPH and the actual speed does not match the target speed then an E9 error is flagged. This error indicates the motor controller system is unable to maintain the target speed.
Speed Feedback Issues
Speed Control Issues
Calibration Issues
OPERATION ERRORS
E16 – Stuck key error
OVERVIEW
If a key press is detected for more than 45 seconds a stuck key error is flagged. This error is primarily caused by a faulty keypad but could be caused by other issues (object on the keypad).
CORRECTIVE ACTION
Reset system power. If error re-occurs replace the keypad with a known good keypad. If error still occurs replace console PCB with known good console PCB.
E18 – Safety switch test failure
OVERVIEW
If the actual speed exceeds limit set for safety switch test a safety switch test failure error occurs..
CORRECTIVE ACTION
Re-calibrate system as listed in system calibration section of this document and re-run safety switch test. If system still fails safety switch test run speed feedback issue and speed control issue tests in the corrective action procedures section of this document.
E19 – NOVRAM Failure
OVERVIEW

If the values stored in non-volatile memory are out of limits or do not match the safety check value stored in non-volatile memory a NOVRAM failure occurs. The system attempts to reinitialize the non-volatile memory three times and if the NOVRAM check fails all three attempts a NOVRAM failure error (E19) is called.
CORRECTIVE ACTION
An E-19 error indicates the NOVRAM has critically failed and needs to be replaced. If an E19 error occurs the console should be reprogrammed with the current software version and the power should be toggled. If this does not clear the E-19 error the console PCB will need to be returned to DCI for repair
