PC&S strives to offer our customers and partners the best value.
Theory of Operation
Initially, SYNC, BUS and GEN LED’s are lit Red and the outer ring will show a single Red traveling LED. When voltage and phase angle are unmatched the outer ring LED rotates according to the system phase difference.
When the BUS voltage is at +/-10% of nominal system
voltage, the BUS LED will change from Red to Green
signifying proper BUS voltage has been established.
When the GEN voltage is at +/-10% of nominal system
voltage the GEN LED will change from Red to Green
signifying proper GEN voltage has been established.
Once the BUS and GEN voltages are at their proper values, and the system has come into phase, the outer ring LED will stop rotating at the 12 o’clock position and change from lit Red to lit Green.
Finally, once all system voltages match and the systems re synchronized, the SYNC LED will change from Red to Green. All LED’s are now Green when the systems are synchronized.
