#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. #ZERO/CAL check perform timing CWhen self-diagnosis function is running by switching on UEC. CWhen RESET terminal is switched on. CWhen is touched. CWhen START terminal is switched on, if either 0 or 1 is set to EXTERNAL START. CWhen [F6 ZERO CAL] on the ZERO POINT ADJUSTMENT screen of the UEC-4800 setup software is pressed. When error is detected CDisplays a message [ZERO ERROR] and [measured torque value]. CDisplays a message [CAL ERROR] and [measured torque value]. 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 Auto ZERO execute timing UEC executes AUTO ZERO after ZERO/CAL check. At the time of self-diagnosis when UEC is switched on. When touching , or RESET TERMINAL is switched on. When external start (START terminal of terminal board) is switched on Auto ZERO execute point \[ \gg Absolute 0 Torque measurement Absolute Auto ZERO execute point ON OFF Torque increase (measurement) Torque sensor Output signal Absolute zero Torque measurement Absolute torque Torque increase (measurement) Torque sensor Output signal
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.

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
