SYN3000
Description
A demo-version of the SYN-WIN software is also available displaying all the above functions with the exception of the serial interconnection to the SYN3000. 4.3.4.1.
Caution Notice to SYN-WIN
The SYN-WIN software provides the display of the actual measured values and also an image of a synchronoscope. Although the synchronoscope looks deceivingly real it can in no way whatsoever be taken as a guide for manual synchronizing. WARNING The timing may not be real time and the displayed measured values and the pointer of the synchroscope may differ from the actual values and position.
4.4. Additional Functions at Software Versions Starting at 2.19 At software versions ≥ V2.19 additional functions are implemented to increase the safety and the comfort for operation. The software version of the SYN3000 is shown on the LC-display (main menu). 4.4.1. Maximum Permissible Phase Angle The SYN3000 has an accuracy of ±0,5° (due to the internal measuring). Now the accuracy at the calculation of the phase angle has been increased. The permissible phase angle now can be also set to 0°, in steps of 1° (in the old version minimum setting was 1°). By this the maximum accuracy at CB closing is ±0,5° (at 0° setting), ±1,5° (at 1° setting), etc. The closing times based on this accuracy are calculated in chapter 12, "Remarks to the Accuracy". 4.4.2. Impulse Length for CB Closing Command At the old version the impulse length for CB closing command could be set with a minimum length of 1 sec. Now this command is fixed to a length of 0,7 sec. Only in mode 4 (synchrocheck) the contact closes for the whole period, when the synchronization conditions are fullfilled. Merely at earlier reset by selection input the closing time may be shorter. See chapter 5.1, "Operating Sequence of the SYN3000". 4.4.3. First Slip Measuring If in mode 1 (generator to bus bar or power line) the same voltage is switched to both sides of the SYN3000 by mistake, the old software has gives a CB closing command, as by this wiring failure the synchronization conditions seem to be fullfilled. In the new software such external wiring failures can be recognized and no wrong closing command can be applied. This is realized be the implementation of the following condition: After selection of the SYN3000 the slip must be at least ≥ 0,025 Hz for one moment for activating the calculation.
