2)  Initial torque error  
UEC provides the error when the time from start torque to cut torque is shorter than the time of 
initial error detect timer.

#Torque Sensor Wiring Check

UEC makes torque sensor cable’s damage, break or short circuit.    The error detection is made when 
ZERO/CAL check is in action.


#Error detection
NEZero check
UEC checks how big the voltage of torque sensor will change from 0(V) under no load condition.   
UEC detects ZERO error if the voltage variation (DPM display zero point) becomes greater than 6% 
of CAL value.   

OECAL check
UEC checks whether sensor setting value in UEC is appropriate to the...

 
&Auto ZERO

This is a function to do correct torque value measurement by doing automatic correction measured 
torque variation due to torque sensor’s ZERO point deviation.    UEC memorizes ZERO point deviation 
confirmed by ZERO/CAL check, includes the deviation degree in torque sensor signal, and converts 
the adjusted torque signal to torque value.      This auto ZERO will not function when ZERO/CAL error.   

Examples of AUTO ZERO 
1)    When ZERO/CAL check detects plus (+) side deviation....

 
16Torque waveform measuring procedure 

Following explains how to measure the torque waveform by using the memory 
HiCORDER or memory scoop.   


1)  Make sure that the setting values are correctly set up, especially check if the connected 
torque sensor’s sensor specifications and the torque sensor setting value agree with 
appropriate CAL value.     
 
2)    Connect the waveform measurement equipment to the ANALOG OUTPUT terminal of UEC-
4800TP.

ANALOG OUTPUT terminal

UEC outputs the analog torque signal voltage in real time by having the torque sensor output signal 
voltage amplified by 1000 times, filtered and attenuated.     

1)    Torque sensor output voltage specification table 
Following is output voltage (x V) when rated load torque is applied to torque sensors.    Output 
voltage changes per sensor specifications.

Error message & contents

ZERO Error 

When more than o6p  deviation off from rated value is detected. 
CAL Error  

When more than 100o6p  deviation off from rated value is detected 
Buffer Full Error 

This error is fired when more angle data to a buffer than the memory unit can accommodate is 
flowed into it (buffer overflow).    The memory capacity is programmable on mode settings of 
“Waveform Memory Function Select”.     
Setting Error 

When not settable setting value is input....

  D/A Error 

When D/A of board is broken down or causes malfunction for some reasons.   
SUM Check Error 

When the setting data memorized in RAM have error.   
Blown Fuse 
1) When the AC fuse (Refer to 4.2 Rear panel H) is blown, you cannot power on UEC.     
2) When the DC24V fuse on the board inside UEC housing is blown, following phenomenon occurs.     
CTool does not shut off even if the torque reaches CUT torque.   
CTool’s lamp does not light.
  

  
Error display screen 
When UEC detects the error that is not related to the fastening or maintenance, cause and the 
countermeasures can be displayed on the touch panel screen.    
 
1)    Touch the error message to move to the cause and countermeasure screen.    It goes same on 
the WAVE FORM MONITOR screen and the TORQUE/ANGLE WAVE FORM MONITOR screen.
