Input and Output check (wiring diagnosis of the terminals and the tool)

By monitoring the input condition to the terminal block and making the compulsory signal output to 
either the terminal block or the tool, UEC checks the incoming wirings of the terminals of UEC, the tool 
and the sensor cable connected.   
 
If you enter the IN-OUT CHECK screen, UEC starts from the check of the input terminals.   









Input terminals now been switched on are colored in blue.       
 
Press 
  to move to the output check.   









 
UEC can do signal output to the output terminals and the tool compulsory.     
CFive items in the left of the screen are the signal outputs to the terminal. 
CTOOL OK and TOOL NOK in the right of the screen are the output signals to the lamps 
integrated in the tool.   
CTOOL VALVE in the right of the screen is the valve output signal to either the terminal or the 
valve integrated tool.   
Touch the item name, and ON terminal becomes OFF and vise versa.         
Item of output terminal now been switched on is colored in red.     
Note: It is possible to do the same input and output check through PC with using the UEC-4800 setup 
software.

Zero point adjustment
UEC displays the values of the torque sensor’s zero point and the cal number confirmed by the zero 
check and cal check.     
Displayed values are of the absolute values.   










[ZERO] shows the zero point value, and [PROOFREADING VALUE] shows the calculated value of 
CAL x Proofreading Ratio x Tool Ratio.   
If the zero point deviates around [0], touch 
 to have UEC correct the zero point deviation.    A 
message      ZERO POINT ADJUSTING…      appears in the screen during that time.




 
						

							  
WORK No. change

UEC makes the work number change by short-circuiting the input signal terminals and the common 
terminal.    In accordance to the setting value of WORK SIG. SEL. of the MODE SETTING screen, the 
input signals to the terminals become different.

Note: If 1 is set to WORK SIG. SEL., you can use the work number from 1 up to 5.   

Following setups are necessary to activate the work number change.     
 
(1)    Determine the work number change method 
If you want to change the work number by the combination of terminal WORK A, B and C, set 0 to 
WORK SIG. SEL. of the MODE SETTING screen.    If you use the signal input of WORK 1, 2, 3, 4 and 
5, set 1 to WORK SIG. SEL.       
If 1 is set to WORK SIG. SEL., the work number can be changed maximum five only.    If you use six 
or more work numbers, set 0 to WORK SIG. SEL.   
  
(2)    Allocate the input signal to the terminal block 
Enter INPUT 1 screen of the IN/OUT SETTING screen.   
GIf 0 is set to WORK SIG. SEL.     
If the work number to be used is two or less, assign WORK A to any of the input terminal from A1 
to A5.   
    If the work number to be used is four or less, assign WORK A and WORK B to any of the input 
terminals from A1 to A5.     
        If the work number to be used is five or more, assign WORK A, WORK B and WORK C to any of 
the input terminals from A1 to A5.     
 
HIf 1 is set to WORK SIG. SEL. 
Assign WORK 1, 2, 3, 4 and 5 to any of the input terminals A1, A2, A3, A4 and A5 in accordance 
to the work number to be used.     
Ex) If the work number to be used is three, assign [Input terminal A3: WORK 1], [Input terminal 
A4: WORK 2] and [Input terminal A5: WORK 3].    You may assign with the input terminal A1, A2 
and A3 to WORK 1, WORK 2 and WORK 3.    
						

							  
%Torque polarity change

Unless torque polarity of UEC is changed over, UEC is unable to either measure the torque of the left-
hand threaded fasteners or control the geared transducerized tools because the torque signal from the 
tool is input in the minus direction.    You need to change over the UEC’s torque polarity for left-hand 
threaded fasteners.    Change over is made by DIP switch in the board inside of UEC.   
















CChange the setting of DIP switch [SW3] in the main board in order to change the input polarity 
from torque sensor.     
CFor the right-hand threaded fastener, set DIP switch 1 and 3 to ON position and 2 and 4 to OFF 
position.
CFor the left-hand threaded fastener, set DIP switch 1 and 3 to OFF position and 2 and 4 to the 
ON position.
CEven if the polarity change is made, the standard EC or MC wrenches for the right-hand 
threaded fasteners do not shut off because of its structure.    Add the external solenoid valve, or 
use left-hand threaded tools.
