SOURCE: Pro Form 745cs Treadmill does not incline

My jack screw needed to be adjusted. It is a long screw about 1" in diameter. If you take the cover off, you should clearly see the jack screw. If you adjust the incline with the cover off, you should see the jack screw rotate. One end of the jack screw may have come out allowing the screw to rotate freely and not raise the incline. If you can reengage the screw, it may work. I don't know if this will help, but I needed to do it.

SOURCE: Pro-Form Sport 1000 treadmill does not stop inclining

Do a Calibration on the treadmill. Take out the safety key. With 2 fingers, hold down the stop button and the speed up or spped plus button. keep holding them down as you insert the safety key, then let go of both.
Press the stop button 1 time, you should see all 0's in the windows, or EP 2P or something weird like that.
Press the Incline up button and then wait. If the incline go up until it stalls then down until it stalls the stops at the bottom, the you are recalibrated, take out the safery key and put it back in to see if all is well. If the incline takes off up again without touching a button, the you have wiring problems or control problems. Call service company to get it repaired.

SOURCE: I have a Sears Pro Form 730si. The treadmill

I believe E4 on ths 730si means that the speed of the motor the sensor is detecting is greater than the set speed. E2 would be the opposite. I believe there is a way to calibrate the speed. Look at the smaller motor controller board.

Hold the upper end of the treadmill with your right hand on the back end of the unit. Using your left hand, pull the lock knob to the left and hold it. Pivot the treadmill down until the frame is past the pin on the lock knob. Note: You may need to push the handrail to the side slightly. 2. Move in front of the back end and hold the treadmill firmly with both hands, and lower the treadmill to the floor. CAUTION: To decrease the possibility of injury, bend your legs and keep your back straight

SOURCE: The incline on my proform treadmill is not working

ICON CALIBRATION INSTRUCTIONS- INCLINE
1) Press the Stop and the Speed Up keys down while inserting the safety key.
2) Press the Stop key one time. The Time window should read EP:2P. Some newer models may also say FP, Pass, or the like. This means that it passes the EPROM test.
3) Press either incline key and the incline will calibrate automatically.
4) THIS IS A VERY IMPORTANT STEP BECAUSE YOU WILL GET AN ERROR MESSAGE IF THIS STEP IS SKIPPED.After completing calibration of incline, press the Stop key and then remove the safety key.



If the incline moves but you it will not operate normally nor calibrate, check the wiring from the incline sensor to the power board. If all looks normal, put it back in calibration and see if you see a blinking “- -” symbol in the incline window when you are calibrating. If not, the incline sensor is bad.

If the incline moves but only just a bit, it could be a problem as simple as the gearbox on the motor being jammed. We remove the motor from the treadmill, reconnect the wiring, and then try to run the incline motor outside the treadmill. Many times, this will unjam it if that is the problem and then reinstalling it in the treadmill will get it to work. If you have the same problem or it doesn’t run outside the machine and you can hear it try to work, you need to replace the incline motor.

If the incline motor does not move, we need to figure out if the motor is getting voltage. Use a simple multi-meter and set it to AC volts. When you put it into calibration, it tries to calibrate the directions one at a time. Measure across the white and black wires first, then measure across the white and red wires second. If the motor is getting voltage you will read 120VAC (or
thereabouts) one one of the measurements. If you have voltage but the motor won't move, you need to replace the motor.
4.
If the incline motor does not move and you have done the voltage test and you do not have any voltage present, there is a problem in the electronics board that supplies the power. If the console is powering the drive motor as normal, you can bet it is getting an incline signal and the power board needs to be replaced (some models have an integrated power board/controller) so if there is only a single board the whole board has to be replaced. It is possible the console is not giving the proper signal but we've never seen it happen in thousands of treadmills.

Why did my treadmill stop abruptly while in use?


Your assumption is correct, if you have a household circuit breaker popping, you have a short or over current situation. If you have too many other things plugged into the same circuit you could be overloading that breaker. Depending on how your home is wired, you could have a few (older homes may have quite a few) outlets feed by a single breaker. If you have used the treadmill in that outlet (with the same items plugged into that circuit), the breaker it's self MIGHT be going bad (popping at too low of current).

For safety, inspect the power cord, for any damage, and be replaced if there is any.

If the power core is undamaged, I would try plugging the treadmill in another circuit. Choose an outlet that was not affected when the breaker popped. It you use an extension cord to get to another outlet, be sure it's rated for enough current. If it still pops the same breaker it's the same circuit, and you need to plug it in somewhere else (probably in another room). If a different breaker pops, then the short in in your treadmill. At this point you will need to know something about electricity to further isolate the short.

USE AN AC POWER ISOLATION TRANSFORMER
AC isolation transformers are common devices in electronic repair shops.
Technicians use them to isolate the power on their repair benches from
physical grounds in the repair shop (pipes, radiators, etc.) This is primarily for
safety reasons.
You can use the same isolation transformers to electrically isolate your A/V
equipment from connected AC power and thus break any ground loops. They
are typically placed in series with the power cord to the projector
We recommend the Tripp-Lite IS 250, IS500 or IS500 models

check this Ground Loop Isolator - RadioShack.com

Do I need the original power cord for my Motorola dct6200?


there is no transformer in the power cord just straight wall power. the dct 6200 does all its power stuff inside the cable box.... thats why there is no "block" on the power cord.

see the diagrams attached and you must test for to isolate the short.
the short can be a) power cord short b) outlet wall faulty with ground test and repiar c) ground to chassis. d) filter short e) power switch short f) coil or transformer faulty. and step on until you elminate the short USE the DVOM or VOM. g)motor h)board main
Before to do something RUN THE software calibration for diagnose, troubleshooting, and fix it.
God bless you

The power wont come on we've cheked the power point and it's fine. Just the walker wont start no lights no sounds


Dear Sir:
Thank you by your question, here some answer:
PROBLEM: The power does not turn on SOLUTION: a. Make sure that the power cord is plugged into a surge suppressor, and that the surge suppressor is plugged into a properly grounded outlet . Use only a single-outlet surge suppressor that meets all of the specifications . Important: The treadmill is not compatible with GFCI-equipped outlets. b. After the power cord has been plugged in, make sure that the key is inserted into the console. c. Check the reset/off circuit breaker located on the treadmill frame near the power cord. If the switch protrudes as shown, the circuit breaker has tripped. To reset the circuit breaker, wait for five minutes.and then press the switch back in. d) Please check the power cord maybe is broker Testign with DVOM(Digital Voltimeter). e) Test the circuit breaker of the House, and Reset, see in outlet box if some wiring is loose.
Thank you in advance, sincerely. Blessing.
If you need additional Help, please contact me.

When using the RCA jack for Audio In on the Stage Designer 50 controller there is always a ground buzz. This happens when using line out from Yamaha Mixer board, iPod headphone out or guitar line out. ...


You have a ground loop. First, ALL interconnected equipment MUST be powered from the same receptacle or power conditioner. You need to put an isolator in that audio line. This consists of a audio transformer with isolation between primary and secondary windings. The function is like a DI box... but they usually don't make those for RCA jacks. One could cobble up using a DI and a pocketful of cable adapters, but it would be less expensive to get a small audio transformer from Radio Shack and make one with a female and a male RCA jack and plug. FIRST thing though is to get everything powered from the same source. Using multiple plugs at different points within a building is ASKING for these problems and also to damage your equipment. Yes, we have to run extension cords to bring power to the mixer from where the amps are at times... You MIGHT find for your problem you can use one of the impedance matching plugs that have a transformer in them. You would need a few adapters to get the connectors.

Two speakers hum noise


Very doubtful that hum issue is ground potential difference from multiple power outlets as power cord is not grounding type (it is transformer isolated). I do agree that it is good practice to connect all audio equipment to common power strip though, especially with pro sound. Check the audio cords connecting your speakers to the coumputer sound card: 1) Make sure they are connected to the correct jacks and plugged in all the way, 2) wipe the connectors off with a clean paper towel wetted with a smidge of WD-40, 3) replace cords if all else fails. I have also seen solder joints fail on the power supply capacitors (due to vibration) causing hum -- but leave this repair to an electronics technician due to dangerous voltages.

Buzzing noise coming out of television when i plug in power cord


Right, the problem is caused by the earthing of the power supply.

You need a box, which isolates the earth from the laptop to the television, known as an Isolation Transformer. This goes in between your laptop and television, and removes the cause of the hum.

The other option is entirely at your own risk, as you're dealing with mains electricity, however, cover the earth pin with some insulation tape, thus stopping the power supply from earthing. Keep a close eye on the condition of your power supply and cable, as you will not be protected against shock if a fault should develop.

The same problem exists with Acer Laptops, as I have one, and use an isolation box when I want to play music in venues from my Laptop.
