Page 4: Description
ASY-203-056 1. Description This is a control device to carry out a synchronous closing safely and smooth in operation of generators in parallel connections. At time of parallel connection, each voltage and frequency are checked and when the difference is within a given value, closing signal is given to circuit breaker ahead of the synchronous point, accounting on advancing breaking time, so that the circuit breaker (CB) can be closed at an exact synchronous point. - Page 5 Voltage difference： ×100(％) (％ indication to AC110V) Frequency difference：F －F (Hz) Green 7 Segment LED：－□.□□Hz Synchronous closing ASY-96-A1 (±0.05Hz specification) -0.05Hz＜ΔF＜+0.05Hz acceleration ASY-96-A2 (±0.02Hz specification) -0.02Hz＜ΔF＜+0.02Hz function 4.1.2 Setting value. 1) Voltage difference (ΔV) setting.

Page 20: Operating Explanation
ASY-203-056 10.2 Operating explanation (1) Frequency control (Governor increase output, governor decrease output) Bus voltage input (V ) and generator voltage input (V ) are input into frequency detecting circuit through wave-form adjusting circuit and dividing circuit, after isolation by a VT. In the frequency detecting circuit, AC cycle is counted and fed into data bus and the frequency is calculated by soft operation (1/cycle).
