VS4000 Technical Handbook Troubleshooting 6. TROUBLESHOOTING The radio terminal VS4000 troubleshooting techniques are described in this section. These techniques are meant to find out failures that cause a bad functioning of the equipment. The information given in this manual takes into consideration the fact that all the III level maintenance operations will be done only by the Selex ES assistance technicians.
VS4000 Technical Handbook Troubleshooting 6.2 RADIO TESTS WITH THE RADIO TEST SET 6.2.1 Tests with Radio Test Set To carry out the Power Test and the Sensitivity Test on the radio terminal, you need a TETRA RADIO TEST SET (IFR) with the power supply cable and a TNC cable, as well as the radio terminal to be tested. Note Several functions can be active on the TETRA TEST SET, depending on the release.
VS4000 Technical Handbook Troubleshooting When the TETRA RADIO TEST SET is turned on, a screen appears on the display with the initials IFR; the test set saves the data relative to the last test carried out in the memory. By default, the TETRA RADIO TEST SET sets itself in analog mode; to select digital mode, press the ”SYSTEMS” key (see Fig. 6.2) to load the TETRA protocol. Fig. 6.
VS4000 Technical Handbook Troubleshooting Fig. 6.4: Channel selection Once the frequency has been found, confirm it by pressing the key that corresponds to the operating frequency of the terminal from among those located to the right of the display; the test set finds the frequency band and, when the “CONTROL CHANNEL” button is pressed, shows all of the available parameters. Enter the value of the parameters using the numeric pad (see Fig. 6.5). Fig. 6.
VS4000 Technical Handbook Troubleshooting Note If the frequency band of the terminal under test does not appear among those available to the test set, proceed by creating a personal “SET UP” to insert it (see IFR manual relative to the TETRA TEST SET). Press any one of the red “ENTER” keys to confirm data entry (see Fig. 6.6) Fig. 6.
VS4000 Technical Handbook Troubleshooting Press the “MORE” key again to access the parameters of the third and last group; none of these are useful for carrying out the test. Note If the parameters of the first group are not entered, the test set remains in “wait mode”; if, instead, the parameters of the second group are not entered, the test set operates anomalously; finally, the parameters of the third group do not influence the test in any way. A screen divided into two parts (see Fig. 6.
VS4000 Technical Handbook Troubleshooting Now turn on the terminal to be tested; it begins to search and then registers itself with its identifier (ITSI), which will appear on the display. When “CALL MOBILE” is pressed, the test set sends a call to the terminal under test; when the terminal accepts the call, it is possible to check the “MODE” data on the test set. Power Profile: ( “Passed” must appear). Other parameters are (see Tab. 6.
VS4000 Technical Handbook Troubleshooting In these tests, the TETRA TEST SET simulates the TETRA network. Power Test When the “CALL MOBILE” button is pressed on the test set, a call is forwarded to the terminal being tested. After having pressed the “RF GEN” button, vary the field using the adjustment knob (see Fig. 6.8), weakening it and thus forcing the terminal to increase the transmitted power until reaching its MAX power (1 W for portable terminals, 10 W for vehicular/fixed terminals).
VS4000 Technical Handbook Troubleshooting 6.3 TROUBLESHOOTING FLOW DIAGRAMS The troubleshooting flow diagrams are gathered in this chapter. These diagrams are meant only for maintenance technical personnel. By starting from a bad functioning symptom we arrive to the corrective operation to be carried out in order to remove the failure; the corrective action can be a simple maintenance operation (III level excluded) or it can end in sending the equipment to the Selex ES assistance centre.
VS4000 Technical Handbook Troubleshooting The troubleshooting procedures are shown in the flow diagrams whose symbols are described in Tab. 6.3. Tab. 6.3: Description of the symbols used in the troubleshooting flow diagrams Symbol Meaning Stands for the beginning or the end of the flow diagram. The symptom of the possible fault is described inside the symbol. Stands for the action to be carried out. This action is described inside the symbol itself. Stands for a decision to be made.
