• You may start the PC program as follows: - by "Start/Program/Woodward/LeoPC" (starting at version 3.1.xxx), or - by a double click on a file ending ".cfg" in the subdirectory "LeoPC". • After the PC program has been started, establish the communication by pressing the "F2" button. This will es- tablish a data link between the unit and the laptop/PC. -
Page 29: Measurement
Example: If a voltage of 400 V is measured without a potential transformer, the secondary transformer voltage must be configured to 400V and the primary transformer voltage must be configured to 00.400V. © Woodward Page 29/59... -
Page 30: Rated Values (Packages Sc & Sc+N)
Enter the rated frequency of the generator (or the utility mains), which in most cases is 50 Hz or 60 Hz. This will affect the permissible limits for synchronization (refer to Synchronization (Packages & SC+N)" on page 31). Page 30/59 © Woodward... -
Page 31: Control Functions
The unit also issues a breaker closure order for synchronous networks, as long as the electrical angle between the two systems does not exceed the maximum permissible phase angle and the monitored voltage differential is less than the configured maximum permissible voltage differential. © Woodward Page 31/59... - Page 32 The control unit uses the time value configured here to determine when the breaker closure command is issued independent of the frequency differential. This permits the breaker contacts to close as close as possible to the synchronous point. Page 32/59 © Woodward...

Page 34: Protection
Example: If a 480 V system has an overvoltage limit of 510 V and a hysteresis of 10 V, the monitored voltage for an overvoltage alarm must drop below 500 V to re- set the alarm. Page 34/59 © Woodward... -
Page 35: Undervoltage Monitoring
Example: If a 480 V system has an undervoltage limit of 440 V and a hysteresis of 10 V, the monitored voltage for an overvoltage alarm must rise above 450 V to re- set the alarm. © Woodward Page 35/59... -
Page 36: Zero Voltage Monitoring (Packages Sc & Sc+N)
The control will auto- acknowledge a zero voltage condition regardless of how "Autoclearing Relays" is configured. NOTE A message is not displayed on the screen for zero voltage conditions. Page 36/59 © Woodward... -
Page 37: Voltage Asymmetry Monitoring
If the control monitors the voltage asymmetry beyond the permissible limit, the voltage differential must fall below that threshold plus the voltage level defined here for the fault condition to be rec- ognized as no longer existing. © Woodward Page 37/59... -
Page 38: Overfrequency Monitoring
Example: If a 60 Hz system has an overfrequency limit of 70 Hz and a hysteresis of 5 Hz, the monitored frequency for an overfrequency alarm must fall below 65 Hz to reset the alarm. Page 38/59 © Woodward... -
Page 39: Underfrequency Monitoring
Example: If a 60 Hz system has an underfrequency limit of 50 Hz and a hysteresis of 5 Hz, the monitored frequency for an overfrequency alarm must rise above 55 Hz to reset the alarm. © Woodward Page 39/59... -
Page 40: Vector / Phase Shift Monitoring (Packages Vdew / G59N)
If the monitored voltage/frequency reaches or exceeds the phase shift limit, the unit outputs the message "Ph. shift". If a re- lay was assigned to this function in the relay manager, that relay will be energized. Page 40/59 © Woodward... -

OFF ....Automatic clearing of the relays is disabled. Pressing the "Clear" but- ton resets the relays. The alarm message in the display is cleared according to how the parameter "Auto-clearing Display" is configured. The subsequent screens of this function are not indicated. Page 42/59 © Woodward... -
Page 43: Auto Acknowledgement Of Messages
Clearing display after 00s Alarm messages, which have been enabled, will be acknowledged after this config- ured delay time expires. This delay will initiate once the measure value ex- ceeds/falls below the threshold limit +/- the hysteresis © Woodward Page 43/59... -

OFF ....The synch-check function is only assigned to relay 3. Relay 2 may be used for other monitoring functions. CAUTION If above parameter is configured to "ON" and a monitoring function is assigned to relay 2, relay 2 will not react if this monitoring function is triggered. Page 44/59 © Woodward... -

The "ready for operation" function is always assigned to relay 1. However, other protective functions may also be assigned to relay 1 additionally. Relay 1 is always configured as Normally Closed (break contact) and will de-energize if the unit is not ready for operation. © Woodward Page 45/59... -
