Description
The range features 2 synchroscopes : LED synchroscope & LED synchroscope with check sync relay, both housed in 96x96mm DIN cases.
Application
The LED Synchroscope is used for manual synchronisation and optically indicates the electrical phase difference between two ac voltages. The LED synchroscope with check sync relay has a relay output which is controlled in Live Bus situations by differential voltage and phase angle and in dead bus where no system voltages are detected. The input voltages are detected by the input resistor and power supply transformer and the microcontroller is programmed to operate the relay according to the preset options.

Adjustments and Settings
In addition to the 16 LED’s used in the synchroscope there are 2 green status LED’s
1) The Diff.V LED will be ON when inside the preset limits. And OFFwhen just GEN voltages are applied
2) The relay LED will only be ON when the relay is energised.
The green LED at 0º geometric will be on between 358º…2º (0º +/- 2ºE)
The Relay Mode will be factory set to customer requirements of Normal or Dead Bus and Diff set to 10%. Should the settings need to be changed i.e. to KWIK SYNC or a different Diff.V this is done by carefully removing the plastic front panel.
Ordering Information
Please Specify D96-LCSYNC on your order and normal or dead bus mode. (The synchroscope will operate on any input voltage 80-440V . Please specify voltage on your order.)
