And, please follow the following notes. There is no function that checks the balance of phase‑sequence detection and three‑phase voltages each. Please inquire separately. Please be sure to separate wiring by the strong electric side, and the wiring by the light electrical side. Please carry out consideration (malfunction prevention) to a noise. Please be sure to ground grounding terminal E (terminal 9) in order to increase the shield effect. Please perform connection after checking schematics. Unsuitable connection causes trouble of apparatus, and a fire and an electric shock. The power must be turned off before installation and wiring works. It becomes the causality of the trouble, burnout, and fire of an electric shock and apparatus. For electric shock prevention, after wiring is completed, please install a terminal cover. 2. Operation method Special knowledge is required to use this product. Please carry out the right handling with reference to an instruction manual. Please do not touch equipment during operation. It becomes the factor that causes a malfunction. Please apply bus voltage after establishing voltage (AC90 to 125V). Since the power supply of equipment is shared, if a voltage upsurge is done gradually, it will do a malfunction by the power supply unstable region. Please make ac input (bus voltage, generator voltage) into non‑voltage after the end of synchronous control. And, please turn OFF a control input (automatic synchronous start, manual synchronous start). However, although ac input is no problem in the state of voltage applying, please give bus voltage as variation within the range (AC90 to 125V). A SLOW side input designating input is no problem with ON. The switching capacity of a control output (optical MOS‑FET relay) is DC100V, 50mA or DC24V, 100mA. Please install the element that absorbs the reverse induced voltage that it generates at the time of switching in the coil of the relay use for the outside of this product. If it is the waveform that is doing inverter control, and a waveform with a large distortion rate, frequency measurement and phase difference measurement may become unusual. Input terminal and output terminal is with a terminal cover. Please install a terminal cover after wiring. Please do not touch a terminal during operation. There is a possibility of receiving an electric shock. Please do not apply a voltage signal, because control signal input is a non‑voltage contact. There is a possibility that apparatus may be damaged by fire. And, if it uses an outside relay for control signal input, please use the relay whose minimum load satisfies switching voltage and current DC12V, 10mA. 3. Setting Please set up with reference to an instruction manual. And, please follow the following notes.

Earth terminal “E” (No. 9) must be grounded, without fail, to raise shielding effect. Separate the wiring both at power source side and signal side, without fail. Care must be paid for noise. 7.4 Precautions for operation 7.4.1 Input and output signal. (1) Input and output terminals are provided with a cover. Set this cover, for safety, without fail, after finish of the wiring connection. Do not touch the terminals during the operating condition. (2) Control signal input is no voltage contact. Do not input the voltage signal. In case of setting an external relay for control signal input, select the relay good enough for minimum applicable load (mA) DC12V, 10mA in switching voltage and current. (3) Switching capacity of control output (optical MOS‑FET relay) is DC100V, 50mA or DC24V, 100mA. An element must be set on the coil of the relay in order to absorb counter voltage at time of switching. 7.4.2 Precautions at time of start of operation (1) Bus voltage must be input after the voltage (AC90 to 125V) is stable. Operating failure may happen under unstable range of the power when increasing the voltage, because the power source of this device is in common with bus. (2) Control input latch is not provided, so that it must be always short circuit at time of selection. 7.4.3 Precautions during start of operation (1) Setting change cannot be performed during action. If it makes a setting change, ac input (bus and generator voltage) non‑voltage or a control start input (automatic and manual synchronous start) is set to OFF.

The change is 16.7V for every 5s, because of the pulse period being 5s. ★③ Frequency difference (Assumed △F＝0.1Hz.) Control within 0.1Hz＝50Hz ±0.1Hz against bus frequency 50Hz. ★④ Governor pulse width (Assumed Fpw＝0.5s.) Frequency control resolution (frequency change per pulse) will be 1Hz×0.5/15s＝0.033Hz/pulse. The change is 0.033Hz for every 1/ΔF (s) because of the pulse period being 1/ΔF. ★⑤ Circuit breaker advance time (25T) 10〜310ms at △F＝0.1Hz 10〜150ms at △F＝0.2Hz This is the setting range. -

Page 20: Simulation Test
ASY‑206‑077 8. Simulation test Quality of this device is fully confirmed, however, simulating test can be carried out under the following guidance in order to avoid trouble in advance. 1) Simulation test After giving voltage between bus input (between terminal 1‑2) and generator input (between terminal 3‑4) and when voltage difference and frequency difference are within the setting value (LED ΔF is “ON” and LED ΔV is “ON”) and the pulse difference between them becomes smaller, signal (±15°) turns “ON” first and then common signal (25) turns on. Voltage difference V ≧V + setting value：Voltage decrease signal (60L) turns on. Voltage difference V ≦V ‑ setting value：Voltage increase signal (60R) turns on. Frequency difference F ≧F + setting value：Governor decrease signal (15L) turns on. Frequency difference F ≦F ‑ setting value：Governor increase signal (15R) turns on. Control will stop under the range out of 90V≦V ≦125V, 80V≦V In case of ΔF = 0〜±0.05Hz, 15R (15L in case of “SLOW” side closing designation) is output at intervals of 3 second. Under above simulating test, closing command signal (25) is output 3 times continuously every phase at synchronizing point, because bus voltage and generator voltage do not synchronize, it becomes synchronizing failure (ALARM) and the control will stop. -
Page 21: Target For Synchronizing Closing
ASY‑206‑077 9. Target for synchronizing closing. (Reference data) In the case of a synchronous closing, a rush current is suppressed and disorder of a system and the shock to a generator are made small. Therefore, it is necessary to make small a voltage difference, a frequency difference, and phase difference. The following figures 1 and 2 show the size of the rush current by the voltage difference, the frequency difference, and phase difference. ／ ／ ／ Figure 1 Figure 2 The target of a synchronous closing makes a rush current 50% or less. Therefore, if it made the voltage difference (about 5%), a phase error (about 5°), and frequency difference (about 0.1Hz or 0.2Hz), the synchronous closing of a target can be performed. -

Page 23: Operating Explanation
ASY‑206‑077 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). Governor control pulse is output, so that frequency difference becomes within the setting value (±ΔF) by the measured bus frequency and generator frequency. In case of bus frequency (F ) ＞ generator frequency (FG), governor increase pulse (15R) is output. In case of bus frequency (F ) ＜ generator frequency (FG), governor decrease pulse (15l) is output. If a frequency difference is within set value (±△F), an output stops. And, it is lighted of LED of △F (inside of set value). (2) Voltage control (Voltage increase output, voltage decrease output) Bus voltage input (V ) and generator voltage input (V ) are input into voltage detecting circuit after isolation by VT. In the voltage detecting circuit, effective value (RMS value) of AC voltage is measured and fed into data‑bus after A/D conversion. The voltage control pulse is output, so that the voltage difference becomes within the setting value (±ΔV) by the measured bus voltage and generator voltage. In case of bus voltage (V ) ＞ generator voltage (V ), voltage increase pulse (60R) is output. In case of bus voltage (V ) ＜ generator voltage (V ), voltage decrease pulse (60L) is output. If a voltage difference is within set value (±△V), an output stops. And, it is lighted of LED of △V (inside of set value). (3) ±15°output ±15° output is measured from the AC signal shaped in waveform. Phase difference is measured by the pulse width from a bus voltage (V ) input (voltage zero cross point) to a generator voltage (V ) input (voltage zero cross point). If phase difference is ±15° of a synchronizing point, a contact signal (±15°) is outputted. And, it is simultaneously lighted of LED of ±15°. -
