The breakdown with common in use process transducer has the following kinds of classification: 1, condition breakdown; 2, hardware breakdown; 3, systematic breakdown; 4, communication breakdown; 5, power source breakdown is monitored. Wiring terminal regards common transducer fittings as the product, its join the difference of function also can affect transducer to output the size of effect. Now will common the condition that causes transducer product by terminal oneself problem to cannot be used tries enumerate, present solution of the most comprehensive transducer terminal problem for you. Above all, should we understand transducer in detail what does the reason of common breakdown have? 1, condition breakdown: Dc passes / long pressure, dc flows too, communication flows too, speed deviation crosses fault of big, ground connection, be short of equal. 2, hardware breakdown: Voltaic board breakdown, spark board breakdown, IGBT breakdown, pulse generator breakdown. 3, systematic breakdown: Parameter of Watchdog breakdown, system breakdown of unusual, clock. 4, communication breakdown: TIMEOUT, OVERRUN. 5, power source breakdown: Should control power supply exorbitant / too low times alarm. Make us specific analyse the problem of terminal next: 1, face plate of operation of switch power source does not have show: The control voltage that should measure control terminal above all and 10V frequency adjust voltage, if be 0, criterion it is normal that terminal is used, need to change otherwise the join product with higher quality; Measure transducer next advocate wiring terminal resistance is normal; 2, transducer cannot measure data into the line: Fault did not discover when the out of service record in examining transducer menu, and it is to operating the operation of each key-press on face plate in incident record have a record. The A10 inside examination transducer advocate board, A22 power source board the LED indicator light that go up all normal, measure the power source taking a line of transducer with test pencil, discovery has one photograph to show abnormal, measure three-phase eventuate with avometer: Vab=390V, vac=190V, vbc=190V. Enter line terminal to discharge place contact via checking a department undesirable. 3, the char problem of the terminal in inversion module: When symptom of fine of all without exception of examination inversion module, should check the insulation between each terminal and ground bad problem, once discover the plastic insulation terminal between P-P1 of terminal of dc generatrix loop and N has char sign, from safe angle consideration, change attaint transducer terminal, transducer recoverable move normally.
