How to measure Voltage in Transforme for Fitness Treadmill

Transformer Test Procedure:1). Make sure that transformer wire connections (CON1) to the drive board are secured. Turn unit on.2). Put multimeter to the AC voltage setting. Insert meter probes into the transformer primary (red)wires as shown. Normal reading: 110V. This shows that there is power to the transformer.3). Test transformer output by probing on secondary (output) wires: black and black, white and white,orange and orange, yellow and yellow

Transformer Test Results :1). If there is no voltage across the primary (red) wires, inspect F1 fuse on the drive board and power to the drive board. 2). If there is voltage across primary wires but none across secondary wires, the transformer is bad.Replace it.

Transformer Wire Colors Normal Voltage Value:
Red and Red 110 VAC.
Black and Black 11-13 VAC
White and White 11-13 VAC
Orange and Orange 27-29 VAC
Yellow and Yellow 10-12 VAC

ERR1 Definition: The display board CPU didn't receive the optic sensor signal. • Explanation: After processing by the drive board, the optic sensor signal travels the 16-pin cable to the display board CPU, which determines motor speed. Components involved include the optic sensor, optic sensor wheel, 16-pin cable, drive board, display board, and connections.

ERR1 Condition: Press speed key; walk belt doesn't move; ERR1 appears. 1. Drive Board a) Inspect drive board components for signs of damage, like bulging, burnt or cracked spots. b) Inspect connections to the drive board, including the ribbon cable (at the display and drive boards), drive motor, incline motor, etc. loose connections are a common cause of ERR1. c) Check the drive board lED Turn on the unit. The should be lit. The EMG indicator should light up and then extinguish after the unit powers up. A lingering EMG light indicates drive circuit trouble, but it can also light up if drive board connections to motors and other components aren't secure. d) Test whether the drive board is sending power to the motor. Put the muttimeter to the DC setting. Disconnect the motor M+M- wires from the drive board. Place probes on the drive board M+ M- terminals. Put the treadmill safety key in place; turn on the power; walk on the treadmill so that the ClK lED lights (this preempts the display from detecting no optic sensor signaling and immediately giving you an ERR1 message, thus allowing you to get a power reading); press the speed up key. The meter should show some voltage. If there's no voltage, inspect the ribbon cable and display board. If they appear OK, suspect the drive board. e) Test drive board components for a short. See Components in the Basic Electronics. 2. Ribbon Cable a) Check the ribbon cable and its connections. Link a spare cable from the drive board to the display board, outside the unit. Test the unit. If it works with the spare cable, replace the original cable. b) Or, if you don't have a spare ribbon cable, test ribbon cable continuity. Wrap solder wire around each probe so you can insert probes into the ribbon cable connector, testing one wire at a time for continuity. 3. Display Board a) Press down on the display board ICs. If you have a working unit of the same kind, swap the display board onto this unit. Test. If all works well and no ERR message appears, replace the original display board. a) Reed Switch (Applies to models with magnetic safety keys only.) Put the safety key in place over the reed switch. Put the meter to the 200 Ohm setting. Place probes on both ends of the reed switch. Meter should show 0 Ohm. If the meter doesn't get a reading, replace the reed switch. 4. Treadmill Motor a) Rotate the motor. It should rotate smoothly. Grinding or sticking indicates wear. b) Check the motor brushes. Uneven wear indicates worn brushes. Minimum brush length: 1/2 inch. Turn the brushes around and reinsert them. Rotate the flywheel. If the motor grinds or sticks, put brushes back in their original position. c) Check motor resistance: Turn off unit. Disconnect the motor M+ M- cables from the drive board. Put multimeter setting to Ohms. Place probes into the motor wire M+ M- ends. Normal reading: 1 Ohm. Move the flywheel slightly and take another reading. Take a few readings, moving the flywheel slightly after each. Readings should be consistent. If the meter shows OL at any test point, replace the motor. 5. Transformer a) Put the meter to the AC setting. Place the meter probes on the transformer output wire connectors on the drive board. Turn on the unit. There should be output voltage. If not, replace the transformer. • 11XX/12XX brown-brown: 10.5VAC • 31 XXl32XXl61 XXl62XX white-white: 12.5 VAC • 6005 yellow-yellow: 11.0 VAC If ERR1 is not resolved, see ERR1 with walk belt movement. • • • • ERR1 Condition: Press speed key; walk belt moves; ERR1 appears. 1. Tachometer Wheel Make sure the tachometer wheel: a) Rotates in the middle of the optic sensor. b) Is clean and free of cobwebs and dust. c) Doesn't have broken or bent teeth. d) Is fastened securely on the motor bracket If the wheel has visible damage, replace it. 2. Optic Sensor Make sure that the optic sensor signal is getting to the drive board. a) With power on, turn the drive motor. The CLK indicator (an lED on the drive board) should light. This means that the optic sensor signal is reaching the drive board. If the ClK indicator doesn't light, replace the optic sensor. b) Push the treadmill belt while pushing speed up key. If ERR1 doesn't appear until you stop pushing the belt, and the display speed values increase, then the optic sensor is good. (On units without a ClK indicator, check optic sensor output voltage: (a) put probes on optic sensor output (b) turn the motor (c) if voltage doesn't vary, replace the optic sensor.) 3. Ribbon Cable a) Check the ribbon cable and its connections. Link a spare cable from the drive board to the display board, outside the unit. Test the unit. If it works with the spare cable, replace the original cable. b) Or, if you don't have a spare ribbon cable, test ribbon cable continuity. Wrap solder wire around each probe so you can insert probes into the ribbon cable connector, testing one wire at a time for continuity. 4. Drive Board Check whether drive board components are burnt or cracked. Check component connections. A drive board power component short usually results in a huge burst of power, making the walk belt speed dangerously, before ERR1 appears. If the walk belt moves before ERR1 appears, but not very, very fast, suspect the optic sensor. 5. Treadmill Motor a) Rotate the motor. It should rotate smoothly. Grinding or sticking indicates wear. b) Check motor resistance. Turn off unit. Disconnect the motor M+ M- cables from the drive board. Put multimeter setting to Ohms. Place probes into the motor cable M+ M- ends. Normal reading: 1-2 Ohm. If there's no reading (OL), replace the motor. c) Check the motor brushes. Uneven wear indicates worn brushes. Minimum brush length: 1/2 inch. Turn brushes around and reinsert them; rotate the flywheel by hand. If it rotates worse than before, put brushes back in their original position. d) High amp draw can indicate a bad motor. Other factors would be a worn walk belt and deck. Run unit power through a current meter. Tum on the unit. Normal amp draw at 3 MPH with no load on the walk belt is 1/2 to 1 Amp. 6. Display Board ICs Make sure that IC contacts on the display board are good. Press firmly on the ICs. Make sure you have the latest CPU version. If ERR1 is not resolved, see ERR1 no walk belt movement.

e2 error on pro form 730 key in belt and motor run about 5 sec and shuts down sensor light blinks but not a steady light


Dear Sir:

I will try to help you, use the patience and carefully: need screwdriver, hex, allen+Dvom(DigitalVoltemeter)


Troubleshooting: ERR2 - Motor Movement

Since the motor moves when you press speed up, focus on the optic sensor, its wire connections, and the

optic sensor wheel. If all seems well at the sensor, inspect the motor.

Optic Sensor

??? Optic sensor wheel - Make sure that the optic sensor wheel rotates securely, without wobbling, in the

middle of the optic sensor. Realign and tighten if necessary. If optic sensor wheel teeth are missing or

bent, replace the optic sensor wheel.

??? Optic sensor wires - Make sure that wires are inserted securely to the optic sensor and to the drive board.

Check wire continuity.

??? Optic sensor - Turn on unit power. Turn the motor flywheel with your hand. The optic sensor

indicator (LED10, drive board) should light. . If it does not light, and all parts above are

good, replace the optic sensor.

Motor

??? Motor arcing - Does the motor show signs of wear - irregular arcing, carbon dust?

??? Motor brushes - Do brushes show signs of irregular wear - cracks, dents, lines? Replace the

motor brushes.

??? M+ M- Wires - Make sure wires are connected properly.

Other

??? Display main IC - To ensure proper signal processing, press down on the main IC on the display

board, marked U5. .

??? Ribbon cable - Ensure that the ribbon cable is attached at the drive and display boards. Check cable
continuity.

Troubleshooting: ERR 2 - No Motor Movement

Turn unit power off and then on to clear the ERR2 message from the display. To test whether the drive

board is putting out power to the motor, insert multimeter probes on the M+ M- connectors and press

the speed up key. . (Note: To avoid ERR2.)

Power to Motor

If the drive board puts out power to the motor, but the motor does not operate, either the motor wires or

motor is malfunctioning. Test wires for continuity. Inspect connections. Perform an ohm test on the

motor . Inspect motor brushes.

No Power to Motor

If there is no power to the motor, either the signal is not arriving at the drive board, the transformer

or inductor is bad, or the drive board is bad. Inspect the following:

??? Display - Does the display beep when you press speed up? If so, the display has sent its signal.

If not, inspect overlay-to-display connections. And press down on the main program IC, marked U5.

??? Wires and their connections - inspect data cable connections from the display to the drive board,

test data cable continuity, inspect M+ M- wires from the drive board to the motor.

??? Inductor (6310 only) - inspect inductor and its wires and their connections. .

??? Transformer - inspect the transformer and its wires and their connections.

??? Drive Board - inspect the drive board for burnt or cracked components. Inspect LEDs (See DRIVE.03

and DRIVE.04). Press on the drive board IC chips to ensure good connection. If the power indicator on

the drive board, LED8, lights, but there is no power to the motor, and other components are good,
replace the drive board.

I just installed a Honeywell HE 360 Humidifier I purchased at Home depot. I replaced a Aprilaire model 110 . I have a 120v power duplex that is hot with the furnace blower motor, on so I assumed the sail switch is NOT NEEDED to sequence the humidifier with the furnace blower motor. Bottom line when I hook it up, with 2 yellow wires connected to my house low voltage wires to the humidistat.. nothing happens. As a check , I tried a bench test, and touchd the 2 yellow wires ,with the unit plugged into wall outlet , assuming the fan should turn on. It did not. So ,thinking it was a defective unit I removed the unit, and took it back to Home Depot for a even exchange. The new replacement unit (same model 360 since I cut the duct plenum opening for that model) does not work either so I must be missing something in the wiring requirements.. Also interesting is the 2 Red wires on the humidifier are NOT needed per the instructions. Not sure what they are there for , Does anyone out there know what the missing wiring issue is ?


Hello, in order to turn your humidifier on with the furnace the 120 volts coming from your humidifer you must hook it up to a step down transformer, then the transformer will provide 24 volts to you humidistat and solenoid valve. So you need a wire from the HUM on your control board to transformer primary side and a wire from neutral on the board to primary side of transformer. Then you need low voltage wire from secondary side of transformer to humidistat from humidistat to humidifier.

my microwave is a 2005


jl, first, are you sure that you have power? Plug something else in to check. Also, unplug the unit, wait a full minute and repower. Sometimes this resets the units. Second, fuses are generally located inside the keypanel area. With the unit unplugged, remove the screws holding the panel on. Inside, you will find at least one fuse. You will also find thermo sensors. They are black, about the diameter of a dime and 3/8 inch thick with two wires coming out of them. Check them for continuity.
