3.Installation and Adjustments

The Synchronizer is mounted in control cabinet together with other electronic equipments. Care should be taken to limit exposure of the unit to extreme temperatures. The unit should be mounted vertically to prevent accumulation of water inside the unit.

     The electric wiring and mounting size is shown in fig.1.

     Caution: High voltage AC would be exist at terminals 1~4 while generator is working, so the synchronizer must be installed tired and people can not touch it. In order to enhance the anti-jamming ability, wiring between synchronizer and controller must be shielded.

After affirming installation and wiring is correct, start to adjust. Method of adjustment is as follows.

1)        First connect a jumper wire between terminals 7 and 8 or disconnect output circuit of relay between terminals 11 and 12 to make generator set can not paralleling.

2)        Adjusting the controllers speed trim of a waiting parallel generator to make the frequency error between the generator and main net bellow 0.1Hz. Observe the state of LED lights on panel of the synchronizer: LED lights of generator,main net,DC power supply are bright.

3)        Close synchronization-switch between speed governor and synchronizer, red LED synchronization allowance light bright and the process of synchronization start.
