CSY-207-093 4.6 How to set up Please refer to the setting values below and change the settings before applying power. If a setting change is made after power is applied, control will stop and an alarm is output. When resetting the alarm, please set the power supply to no voltage. (Arrangement of setting device) Auxiliary supply Dead bus closing signal...
CSY-207-093 5. Control function 5.1 Control range Bus voltage :90 to 135V AC Bus frequency :50±3Hz, 60±3Hz Generator voltage :More than 80V AC Frequency difference:Within ±4Hz Output is stopped except for the above. 5.2 Control output and description (1) Display of frequency difference within setting (ΔF). If a frequency difference are within the range of ΔF setting value, LED lights of ΔF.
CSY-207-093 6. Operation overview (1) Before application of auxiliary power [bus voltage (VB) and generator voltage (VG) are no voltage]. ① When checking the wiring to this product, make sure that all power and signal lines are in a no-voltage state.
CSY-207-093 7. Test Please refer to the following when conducting a mock test. 1) Performance test ① Apply auxiliary power and verify that the "POWER" LED is illuminated. ② Apply voltage to the bus input (terminals 1-2) and the generator input (terminals 3-4). When the voltage difference and frequency difference are less than the set values (ΔF LED ON, ΔV LED ON) and within Δφ, confirm that Δφ...

CSY-207-093 9. Principle of operation 9.1 Block-diagram 9.2 Explanation of operation (1) Frequency measurement. The bus voltage (VB) input and the generator voltage (VG) input are isolated by a VT, then input to the frequency detection circuit via a waveform shaping circuit and a frequency dividing circuit. In the frequency detection circuit, the cycle of AC is counted, taken in the data bus, and the frequency is calculated by software calculation (1 / cycle).
