12TOOL CONTROL 
UEC can memorize the total fastening number and pulse number since a tool is brought into use.    It 
enables UEC to provide a notice of simple maintenance such as oil change by [WARNING 
COUNT/PULSE] and parts replacement/overhaul by [REPAIR COUNT/PULSE].

13Functions 

Fastening control
Fastening control method is selectable from 5 options. 
  Control method  :  1  Torque monitor  
   :  2  Torque control  
    :  3  MC/EC wrenches Torque control   
    :  9  T type wrenches Torque monitor 
 
1)  Torque monitor Control method: 1 
This is used mainly for torque monitoring of the angle nutrunner UAN series, which shuts off by 
mechanical clutch.  When 0 is set to EXTERNAL START, UEC starts torque measuring by the 
external start signal input.    When 1 is set to EXTERNAL START, UEC starts torque measurement 
when detecting the start torque or greater torque and provides the judgment when the judgment delay 
timer comes up after the torque gets lower than the start torque.     








2)  Torque control   Control method: 2
This is mainly used for torque control of nutrunner.  UEC switches on VALVE terminal to have 
nutrunner operated and controls its torque.    Switching on external start signal, nutrunner operates 
and UEC starts torque measurement.  Nutrunner continues operating until torque reaches CUT 
torque.    UEC provides judgment when judgment delay timer comes up after the torque gets lower 
than start torque.

							 & 
3)    MC/EC wrenches Torque control Control method: 3 
This is to control torque of either MC or EC wrenches.  UEC starts torque measurement when 
detecting the start torque or greater torque, and switches on valve terminal to stop the tool when 
reaching torque cut level.    UEC provides judgment when judgment delay timer comes up after torque 
gets lower than start torque.     
When torque measurement delay timer is set up, it starts functioning when detecting start torque or 
greater torque.  UEC cancels torque spike at the bolt seating point by suspending torque 
measurement until torque measurement start delay timer comes up, and then starts torque 
measurement.

5)  T type wrenches   Torque and fastening time monitor   Control method: 9
UEC monitors torque and fastening time of shut off tools.  






 
 
UEC starts torque measurement when detecting the start torque or greater torque, judges the tool is 
shut off when provides judgment when the fastening time between peak torque (x in a graph) gets 
longer than the judgment delay timer, and provides judgment.   
After UEC provides judgment, reverse completion delay timer gets functioning when the residual load 
torque gets lower than start torque by the tool’s reverse operation.    Timer timeout is regarded as the 
completion of tool reverse operation, UEC switches off VALVE to cancel the tool’s operation start.     
 
Fastening time 
(1)    Fastening time measurement start point

(2)    Fastening time measurement end point 
CA point is determined by deducting the judgment delay timer off time from the time required until

Upper and low limit judgment

UEC provides judgment whether or not the detected torque, angle or pulse number is within upper and 
low limit.   
Upper and low limit judgment is made against torque or pulse numbers until fastening is completed.     
Upper and low limit of torque is set in TORQUE LOW and TORQUE HIGH in the BASIC SETTING 
screen.  
Upper and low limit of angle is set in ANGLE LOW and ANGLE HIGH in the MODE SETTING screen.   
Upper and low limit of pulse number is set in PULSE LOW and PULSE HIGH in the MODE SETTING 
screen.

CWhen 1 is set to ALARM BUZZER, UEC gives single sounding “Pi” for each fastener OK 
result, and double sounding “Pi-Pi” for COUNT OK.

f







Note)    Above is an example of linear torque change curve.



1)  Start torque error 
UEC detects the time from the time when external start terminal is switched on till the torque 
reaches start torque, and provides the judgment if the torque reaches start torque before the start 
torque error detect timer comes up.     
[Note]  
CUEC could not detect the error if the preliminary fastening condition varies much per bolt or nut.     
CUEC could not detect the error when it takes long to fit the nutrunner socket to work piece.     
 [Setting value]  
CST. TORQUE ERROR detection: 1 
CST. TORQUE ERROR timer: 1 – 9999 [msec] 
eHow to set` 
CMonitor the time from external start input to start torque of the correct fastening, and determine 
the setting value.  The time is displayed on TIGHTENING (TSS) of the MODE SETTING 
screen (second page).
