The Maintannance And Operation Tips Of JQTV-9002   Vibration Controller  

Q:What happened if PC shut down during vibration test?

A: Nowadays, computer viruses is increasingly rampant, people sometimes cannot avoid it. There is one customer ask me, what happened if computer crashes during vibration test? I told him, it does not matter whether PC shut down, LAN cable disconnected or WIFI disconnected, the controller will be still running according to the settled schedule, once you reboot computer & restart controller software, or reconnect the network, you can continue to control & monitor on the running test. In a certain meaning, it gives great safety assurance to the shaker and power amplifier. Moreover, it helps customer avoid doing a repeat test, especially when the test is already running over hundreds of hours. 

Q:Why say JQTV-9002 is new generation controller?

A: The current new generation controller has following features: Ethernet connection, no-fans structure to reduce background noise, 1GB internal flash memory stores test configuration; also it should has some innovative functions, like none-Gaussian control, Sine-on-Sine control, while VENZO 800 poss essesall of these features.

Q:Does JQTV-9002  can do 2-axis control? How?

A: Absolutely yes, but you should choose model JQTV-9002. In normal configuration, JQTV-9002  only has one drive channel and one AUX channel, if customer needs MIMO control, we will change AUX channel to drive channel, this does not means changes in hardware, you just need our MIMO control software.

Q:Does JQTV-9002  have grounding problem?

A: No. Because JQTV-9002 series adopts 100 Mbps Ethernet pot connected to PC, also the hardware is floating ground design which reduces ground loop problems.

Q:Vibration controller, amplifier and sensor how to connect?

A: Vibration test system is mainly composed by the vibration controller, amplifier, shaker table, sensors and a PC. Connect the Drive to the input terminal (IN) of power amplifier, the sensor installed on the top of shaker table or installed with fixture on the shaker table. The information of vibration table and amplifier please refer to the data provided by the manufacturer.

Q:Vibration controller connects with PC via network interface, how to set up the network-related information?

A: There are two ways to connect vibration controller with the PC: The first way is connecting network interface of the controller directly with the PC network interface through the network cable, start the controller hardware and "Ready" light is blue, and it indicates the network is connected. Open the software and click Set Licence icon in the Start Page or select Tools-Set Licence, to open "Set Licence" dialog box. Before leaving factory, the default IP address of the controller is 192.168.1.166, so enter the default IP address-192.168.1.166 in IP column, and then import password file from the installation CD under the Password folder. The password file is named as “Licence_Hardware serial number.dat”. The PC IP address is set to "192.168.1.XX". PC IP cannot be set to "192.168.1.166", which is not set as the vibration controller’s IP. In order to test whether the network connection is normal, run command "Ping 192.168.1.166"under the windows DOS to test whether the vibration controller network is normal. The other connection method is connecting vibration controller with HUB (switch), make the controller become a node in a LAN, but ensure that PC and vibration controller network segment is consistent, namely "192.168.1.xx". Then any one of computers within this LAN can control this controller. When using a wireless router (AP) network, the vibration controller is connected with a router, and then PC can through the wireless network to establish communication with vibration controller.

Q:How to import the updated calibration file?

A: Suggest send vibration controller to the factory for calibration annually, calibration file generated after calibration needs to be imported into the PC, double-click VibExpert icon on the desktop, click on the Tools drop-down menu, and then select the Import Calibration File option in the dialog box that opens, click Import calibration file button and click OK to complete the new calibration file import.

Q:The novice runs vibration controller software, how various settings?

A: First, open the software, enter the Start Page; in Start Page, select the desired application module, such as the sine test that select the icon Sine; random test module select icon Random. Start an application module usually carried out smoothly in accordance with the following parameter settings: engineering units, input channels, shaker parameters, reference spectrum parameters, schedule and etc. Parameter setting details see the contents of the subsequent chapters. All parameters can be saved as the default parameters, the next time enter test can follow the same test set. Set parameters and check and correct, you can click on the Start test button. This is the common test steps and order, and if any special operations or doubt, please consult the supplier and technical personnel.

Q:Does vibration controller with a PC with a network connection can use Wi-Fi?

A: You can use Wi-Fi. Use wireless router to connect vibration controller, PC through the wireless network card and the wireless router connected with vibration controller. In the Settings folder, set up IP, save and exit.

Q:If I forget the IP address of the controller, what can I do?

A: If you forget the IP of the controller, and prompt connection is not successful, you can recover controller’s IP to the default factory configuration, just according to following steps. If the instrument is already open, turn off the controller power first, then restart controller, wait for Ready light on, press and hold Abort button on the front panel for more than 4 seconds, until control light starting blinking, then the controller’s network configuration has been recovered to factory configuration, that is IP 192.168.1.166, network segment 192.168.1.1. Then restart controller to effective this default network configuration.
