  • Page 17: Principle Of Operation

    7.2.3 Frequency measurement (Period measurement principle) FT 3000 tachometers work on the continuous period measurement principle. The measuring chains for 3 frequency measurements are implemented in hardware using ASIC’s. Each of the 3 ASIC’s contain a counter to measure the period duration of up to 3 frequencies.
  • Page 18 Always remember to reset the Max value memory following testing with internal generators. Speed measurement and over speed trip monitors are separate functions within the FT 3000. In operation, there are 2 main reasons why the recorded Max value may not correspond to the limit setting: - the trip point is reached but the machine runs on until the shutdown valve has closed.

  • Page 19: Acceleration Measurement

    Operating Instructions FT 3000 JAQUET AG - gear machining inaccuracies, coupled with a low number of pulses configured for the trip setting may result in the over speed monitor activating the trip relay at a speed apparently lower than the limit set. The solution to this is to increase the number of pulses used to say 20% of the number of teeth on the gear 7.2.3.3 Comparators...

    Operating Instructions FT 3000 JAQUET AG 7.2.5 Limit value control There are 4 limit values available. There are independent upper and lower set points for each so that almost any hysteresis is possible. Limit1, Limit2 and Limit3 may be assigned to either speed monitor 1, speed monitor 2, speed monitor 3, comparator 1, comparator 2 or comparator 3 via software configuration.

  • Page 22: System Monitoring

    Operating Instructions FT 3000 JAQUET AG 7.3.4 System monitoring The FTFU 3024 and FTK 3072 run background self tests on the most important CPU and EEPROM functions. SelftestOK is set (=1) when no fault exists, otherwise reset (=0). SystemOK in the status byte is an AND function of SelftestOK, SensorMonitorOK and PSOK. The constituents of SystemOK can be masked by software configuration.

    Testing is only possible if there is no system fault, a speed monitor has been selected and TestOn is set active. The status of internal commands SpeedMonitorInputASelect, SpeedMonitorInputBSelect, UnderOverSelect and TestOn can be changed via configured binary inputs or FT 3000 PC commands. 7.8 Frequency outputs 3 frequency outputs are available.

  • Page 25 Operating Instructions FT 3000 JAQUET AG The FTBU card is designed to combine different trip commands to provide global shutdown control within the IEC 61508 SIL 3 regime. The overspeed functionality of the FT3000 is SIL 3 certified. The FTBU extends this certification to encompass trip signals from other sources such as temperature, pressure etc alarms.

    Limit 4 is always defined as Comparator. The FT 3000 Windows software will allow a minimum pulse value to be set, which is appropriate to the limit setting. In the event that trips occur at speeds apparently below the limits selected, then this may be the result of gear machining inaccuracies.
