RE-ENABlE BREAKER CONTROl fUNCTION

Re-enable the break control function by removing the jumper wire between Terminals 7 and 10 and /or reconnect the relay wire

between Terminals 13 and 14 or Terminals 14 and 15. Synchronization and paralleling may now be performed.

For a final check, start the engine and synchronize the system to ensure that all adjustments are optimized.

If performance is unsatisfactory, consult the trouble shooting section.

DEAD BUS OPERATION

If the MAINS input is missing, the synchronizer will not attempt to synchronize the system. A separate system may be used to

close the oncoming generator onto the bus which will provide a reference to which others may synchronize.

vOlTAGE MATChING AND MONITORING

GAC offers additional modules for support.

The VMA100, when combined with the SCY6714 combines all the voltage monitoring functions and adjustment functions.

OBTAINING NEUTRAl OUTPUT

Once synchronization is complete, and the units are parallel, the synchronizer should be reset to its neutral output and placed in the

disabled position.

Use one of the following to set the synchronizer in a neutral output, ready for its next use:

•

Following the wiring diagram review the switching method that resets the unit by disconnecting the synchronizer output from the

speed controller and opening the reset line at Terminal 5.

•

Disconnect the MAINS (Terminals 3 and 4) to reset the synchronizer. The synchronizer now assumes a neutral position with Termi-

nal 6 holding a constant output voltage of 5.1 V.
