1. Possible Issue:   A message on the handle display 

indicates a “Needle Sense Failure.”

 

       a.  Make sure the Speed/Needle Sense cable is 

properly connected to the control board and to 

the sensor inside the machine front cover.

 

      

 b.  With the machine front cover open and all 

cables attached, power up the machine and 

verify that the green LED D4 “Needle” turns 

on and off to indicate Needle Up and Down 

positions as you rotate the hand wheel (D4 

works the same way as the “Needle” LED that is 

mounted to the internal Needle/Speed Sensor 

board at the main shaft, sometimes called the 

main shaft encoder.

 

       

c.  If the LED does not turn on/off properly, 

determine whether the encoder disk has been 

damaged, is dirty, or is loose on the main 

shaft. Make sure the encoder disk is positioned 

properly in the sensor board . 

       d. If all connections are good, then it may be          

            necessary to change the encoder board and          

           cable .

Indications of Speed/Needle 

 

Position Sensor Failure

 

2.  Possible Issue:  Running the machine in manual  

mode, the motor attains full speed prior to 

reaching 100% on the display.

 

     a.  This can be caused by the Speed/Needle 

sensor missing some of the speed pulses. First 

run the “Speed” test within the “Diagnostics” 

menu on either the front or rear handlebar 

(refer to the “Diagnostics Tests” section in the 

user manual). If the displayed value does not 

settle on 100 after pressing the “Start” button 

on the handles, there may be an issue with the 

motor-speed encoder.

     b.  Remove the machine front cover and double-

check the “Speed” LED (D6) on the control 

board. It should flash on/off 100 times per 

revolution.

     c.  With the front cover open verify that the 

sensor is in the correct position and that the 

disk is not dirty or damaged .

     d.  If the disk appears to be in good condition, 

slowly rotate the hand wheel with power on 

and all cables connected while watching the 

“Speed” LED. It should turn on and off with 

each of the 100 segments of the outer encoder 

disk. If some segments fail to cause the LED 

to turn on or off, the sensor board or disk 

position may need to be adjusted or replaced.
