Carnielli Support | Error Codes CTP 604 - 704-804

If you need spare parts or assistance, please contact us

Communication error

1. Check the connection cables between the motor controller board and the console. Check that they are properly connected and are not broken / cut off midway.
2. If the wires are OK, the motor and console need to be checked.


Lack of speed signal

No speed signal

1. Check the speed sensor, check that it is in the correct position, check the power cord. Try changing the power lead of the deck.
2. Try to replace the speed sensor
3. Alternatively, the defect may be with the motor or the controller

E04 / Er07

Excessive motor absorption

1. Likely a fault on the motor or motor board.
2. In some cases both components are at fault


The Body Fat program does not take the signal pulse

1. Try to dampen your hands, holding both sensors
2. Check the connections of the hand pulse sensors
3. Replace the cables and / or the heart rate monitors


Purchase the professional testing service of your motor board and motor to accurately identify the fault on your treadmill and avoid unnecessary expense for replacing good components or request a home service call.

B) noise from the mechanical transmission of the footboard

The noise may come from the bearing seat ot transmission post.
1) try to rotate the bearings to detect the loud one.
2) If necessary, replace the defective bearing using a puller.

CAUTION: Always use a puller to remove the bearing to prevent damage to other components. Similarly, use a suitable tool to put the new bearing in place.

C) noise from the drive belt

If the noise is not due to the motor or the bearings, then it can derive from the drive belt. When the belt skips or slides, this causes noise.
1) tighten the belt by increasing the distance between the belt and motor.
2) If the belt is damaged, replace the belt

D) noise arising from other components

1) check the rubber leveling pins and adjust if necessary
2) check if the rubber footrest is correctly centered on the base. Center it if necessary.

Treadmill pushbutton tutorial

On many treadmills, there are additional buttons on the handrails for the control of the speed and incline of the motor.

For replacement proceed as follows:

Preliminary Note: In some models the fastening screw is located under the handrail on the side opposite to in controls, in this case it is not necessary to remove the silkscreen

¬ removing the silkscreen;

¬ removing the screw;

¬ unplugging the cable that goes into the rear connections;
¬ replacing the defective part and restoring.

The preceding photo shows the tilt and speed control connectors available for some models of treadmills. Others accept 3 or 4 pin connectors regardless of the type of controls.

Tutorial for closing the treadmill

Pay close attention when folding away the treadmill as it may damage the cables or the other parts of the treadmill if they are in the wrong position.

First of all, before you fold the treadmill make sure that the running deck is in the lowest position possible, otherwise it may be damaged:

¬ then press down on "INCLINE -" until just before the elevation motor reaches the end of its course; pressing the button again to make sure that the deck does not move further;
¬ verify that the cables connecting the treadmill do not remain "pinched" or squeezed especially at closing points and if there is a notable resistance double-check to be sure;

In the case of any problems in the closure of treadmill verify that the rear frame during the lifting movement does not have obstructions on the column, screws, etc.. Also check the operation of the piston support tilt and chrome-plated and varnished square tubes;

it is advisable to oil or grease the chrome tube and the piston in case there is friction on the parts. Also check the functionality of the pommel closure and make sure it is tightly screwed.

Errors on the console of the treadmill: E1 | Support for Roger Black, Bremshey, DKN Technology, Proform, Weslo

E1: when the E1 message appears on the console, it means that the computer has not received the correct information from the speed sensor in the motor compartment of the treadmill.

Solutions to the problem;
¬ Check that the speed sensor is correctly connected to the motor board;
¬ verify the presence of the magnet on the pulley of the front roller;
¬ Check that the sensor cable is not damaged, or there is no damage to the sensor;
¬ verify the distance L = 2-4mm from the sensor magnet on the front roller pulley; 

if it is too far away or too close can cause error;

If it is an optical sensor, make sure it is properly aligned 

¬ if the problem seems to be in the sensor, or the sensor cable replace it (buy it here: speed sensor for treadmill). Almost always, if the belt runs for a few seconds (4-10) before doing showing E1 or if the fault remains the same with or without the user on the deck, it is a defect of the sensor. Instead, if the belt does not start at all, the defect must be on the board and should be looked into and tested (and possibly the motor) in a specialized laboratory (contact us for information).
¬ in severe cases the defect depends on the board or motor of the  treadmill

How to analyse electronic problems in treadmills

1. Verify if the controller is faulty:
a. when the treadmill only works for a while or is not working at all, first of all check the status of the green LED on the controller. If the green LED continues to blink, it means that the controller must be replaced with a new one;

b. if the green LED stays off all the time, it means that the controller has no problem and is working properly. At this point you should check that the computer and all the wiring are all ok, in particular that the wiring is not broken. Where necessary, cross-checking with a new computer and wiring.

Restart the treadmill every time you run a test. You should also check the speed sensor and replace if necessary.

2. Treadmill board LED meanings

LED1 (green LED)

1. The code:
a. 1 flash ... reading the trigger
b. 3 flashes ... the power KO, replace the card
c. 4 flashes ... current overload, turn off and on again
d. 5 flashes ... overload of motor voltage
and. 6 flashes ... successful software installation
f. 8 flashes ... the motor voltage is lower than the expected value after giving the start command

2. Overload Indicator: This green LED lights when the current is above the set value during operation. If the overload continues for 3 ~ 5 seconds, the treadmill will turn off and the green LED flashes 4 times. Turn the treadmill off and on again.

LED2 (red LED)
Speed ​​Indicator: This red LED lights when you change the value of the speed of travel (either increasing or decreasing) and turns off when it reaches the desired value. 

LED3 (red LED)
Tilt Indicator: This red LED lights when you operate the incline on the treadmill (both
upward and downward) and turns off when it reaches the desired value.

Some tips to check for defects in the motor (search our blog for more tips and information on how to test motors)

How to check if the treadmill motor is faulty:

a. The motor is short-circuited between the frame and red or black wires: often the output power source of the motor board burns (this can also be caused by a defect in the controller), or the house circuit breaker skips, or the board shorts and the motor is always at full speed (this can also be caused by a defect in the controller).

b. The engine loses its magnetism, the motor has no strength: this happens when the engine is operated for long periods and is overloaded (overheated); you could also check for unstable performance of the controller, increases and decreases in the speed of the engine, or the engine "has no strength." Measure the number of revolutions of the engine to determine if it is still good

See the example of a 180V/4200RPM motor:

the relationship between speed and revolutions is proportional

If the measured speed is outside the range of variation (5%), the motor should be replaced.

c. The motor brushes are defective: if the brushes are not inserted correctly or their surface is not smooth, it can cause sparks and noise while working. The defective brushes should be replaced and you should run the engine 1-2 hours at full speed before using the treadmill.

d. Shorted or broken windings, abnormal consumptions: in the case of individual windings shorting or breaking the motor returns generally abnormal consumptions (greater than 1.5 A with the motor connected to the belt, or greater than 500mA with the motor disconnected - and not connected to the belt) or fails to comply with the number of revs. This is more risky because the motor could start (maybe help it by pushing it) but it will quickly damage the board.

1. Under the deck, welded on the frame there are two guides.

2. Temporarily fold the belt under the guide.

3.  Measure the distance between the deck to the guide: this should be between 17 and 18 mm.

4. If the distance is different from that specified, use a wrench (10 mm) or another tool to restore the correct distance.

5. Be extremely careful to do it exactly on the point shown in the figure to avoid damage to the guide.

6. Repeat the same operation on the other guide.

7. Make sure the belt is even and tight, following the instructions on our blog.

treadmill doc: protections on treadmill controllers

The Treadmill MCB provides some protections as the followings:

1) prevent jerky (protect user's safety): when IGBT unit burned out/ motor is jerky, relay  switch turns off automatically then motor stops.

 2) protection for motor and controller board. Max current limit (to be set via potentiometer)
3) protection of motor short curcuit (protect MCB from burned out): when motor's short curcuit was detected, relay switch turns off automatically then motor stops.

4) restrain motor reversionary current(protect MCB from burned out): use the speedy diode to protect against current that come back from the motor.

Treadmill motor AC / DC comparison

Hereunder it is brief description about DC/AC motor:

DC motor:
Provides larger power to the treadmill when AC/DC motors are the same volume.
The carbon brush needs to be replaced after using by periodic time because abrasion; so is the armature.

AC motor:
Higher prime cost
The unit price of frequency transformer is more expensive.
No interference of carbon brush, fewer technical problems

AC motors are usually equipped on professional treadmills since they last more

treadmill short circuit

Treadmill short circuit usually means motor is burnt, melting insulating material. This causes the motor to drive the current to the chassis and short-circuit.

"burnt" treadmill motor
When the treadmill causes a short circuit you need to check first the motor. If it's in short circuit itself, you have to replace it.

Icon MC2000 - MC2100 | calibration procedure


If you need spare parts or assistance, please contact us










Buy a secondhand MC2100 controller to on our eshop or test the card and board of your treadmill.

ZY02V1.1 card (DIP) tilt recalibration


This procedure  is to calibrate incline motor on the ZY02V1.1 (DIP) card. Calibration must be performed each time the card is replaced in order to restore the parameters of the minimum and maximum elevation motor. Otherwise the motor elevation forces itself too much and burns.
1) remove the safety key
2) press and hold the button on the motor board, turning on the master switch
3) Press and hold the button until the console does not beep
4) Release the button and wait for it to finish (the carpet goes up and down by itself)
5) Put the safety key back in and test the elevation. If you still feel it forces itself, repeat the operation

Caution: DO NOT stand on the carpet during the recalibration

Standard connections as replacement of Greenmaster controllers:
12 - yellow
13 - black
14- blue
15 - green
16- red

1. It is advisable to add a fuse on AC input and a filter network, when they are not already installed on the treadmill

2. Connect terminals 1-2 to the AC

3. Connect the terminals 3-4 to the motor (in most cases, 3 to red M+, 4 on black M-)

4. Connect the terminals 12-16 to the power input of the console.

5. Connect terminals 13-14-15 to the output of the control console .

6. It is possible to connect terminals 9-10 to the safety. Open circuit between 9 and 10 corresponds to STOP.

7. It is advisable to check that the absorption of the motor (on terminals 3-4) without the user being less than 1.5 A and the absorption w user at 5 km/h less than 4A. If levels are above you should check the transmission, the motor and the proper maintenance of the equipment.

The color scheme shown in the picture refers to the standard wiring in lieu of Greenmaster card types (mounted on Energetics, Roger Black, Diadora, Reebok).

Special cases

1. If the console is not supported (does not give a linear signal) you can replace the console command with a potentiometer (image attached)

2.If the treadmill has a speed sensor it should be connected directly to the relative signal cables of the console. In this case the speed control is performed by the console.

MC2100E icon repair | LED meanings

If you need spare parts or assistance, please contact us
To find out if the board hasn’t been corrupted etc. …these procedures must be followed

- With the board installed and treadmill switched off at the main switch, keep an eye on the red LED on the board (the only one there). If it is turned on by the main switch, LED MUST NOT turn itself on at the same time as the switch, but it should turn on after a slight delay.

At the beginning is a "flash" almost imperceptible, then lights steadily. If it happens the LED to light up immediately after switch on the treeadmill, the board is corrupted and you will have to replace the board (repair is not possible due to IC corruption).

Other cases in which the board is not repairable, always linked to the LED are:
- LED fixed on immediately with a dim light.
- LED off completely, but the dashboard is on (likely to be the microprocessor).

If the card is not corrupted or does not have a damaged microprocessor, then it may be possible to repair it.
