#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 connected torque sensor’s 
wiring and the specifications.  UEC checks if the deviation is less than 
6% from CAL value to 
provide CAL error by applying simulative electric pressure to the torque sensor so as to put the torque 
sensor in the virtual condition under rated load strain.     
UEC detects Cal error if the torque sensor is not connected with UEC correctly, or its wiring and the 
specifications does not fit to UEC set up.

CBuzzer sounds.
CTORQUE NOK terminal is switched on. 
						

							 
&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.  
 











2)    When ZERO/CAL check detects (-) 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.   
 
 
 
 
 
 
 
 
 
 
 
Note)      UK-PLUG’s red wire: connect with torque signal   
UK-PLUG’s black wire: connect with 0V (GND) 
 
 
3)  Touch 
, and UEC makes CAL check, and Memory HiCORDER will display CAL 
waveform height (rated torque applied electric pressure).
  
 
4)    Confirm CAL waveform height, and then set and adjust waveform measurement tool.     
 
5)  Perform torque waveform measurement.

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.

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

							19. Networking 
The controller has several networking options available including Ethernet and hardwired field bus.  All 
parameters pertaining to networking are configured  in the web interface via its Ethernet . 
19.1  Ethernet  
Each Ethernet connection can be configure d to communicate with most popular plant equipment  
including data collection servers, laptop software, and PLCs. 
Ethernet ports by default are set to an IP address of 10.10.30.150 and need to be changed before being put 
into service.  
To gain initial access  to the controller: 
   Configure a computer’s Ethernet port to an IP address of 10.10.30.xxx.  Do not set it to 
10.10.30.150 ( that address is assigned to the controller ).  10.10.30.99 works in most cases.  
   Connect an Ethernet crossover cable from the computer to the controller.  
   Launch the computers web browser.  Type the controller IP address (10.10.30.150) into its 
address bar.  
   Navigate to the communications page.  
   Set the desired IP Address, IP Mask, and Gateway.  
   Cycle power on the controller and connect it to  the network. 
19.1.1  Web Interface  
The controller’s web interface is available from any computer on that has access on the local network.  To 
access  the web interface  launch a browser and type the controller IP address into its address bar.  
From the interface you  will have access to the controller’s status, internal data files, parameters, and time .  
The pages do not automatically refresh but selecting refresh from the browser will reload the latest 
information from the controller.  Data files will be standard ASC II text in CSV (comma separated 
variables) format that can be opened in Microsoft Excel and other programs.  
On  page s with parameters there will be a submit button to apply any changes.  All parameters on the page 
are submitted when the button is hit. When  submitted each parameter will  get range checked against 
allowable limits .  If a parameter is outside of its range it will be limited to its minimum or maximum 
value.   When the page is refreshed (F5)  the edit fields will contain each parameters final value.  
19.1.2  Security  
The web interface has an  option to add a user password for security .  A password is never required to 
view the web pages on the controller.  It is only required to make a change to a parameter.  If the 
controller password is not set (a zero lengt h string) the user will not be  prompted to enter a password for 
any changes.  The controller is shipped from the factory without a password.  
The security feature utilizes the authentication built into the browser.  When a  chang e to  a parameter is 
made  the  controller checks the programmed password.  If a password is required the controller will 
request it from the browser and in turn the browser will prompt the user.  The browser will request a
