The function of the fuse F4 within the square wave inverter circuit is to provide instant protection against overload. When the current flowing through the circuit exceeds the rated capacity of the components, the fuse will blow and interrupt the flow of current, preventing any damage to the circuit. This helps to ensure the safety and proper functioning of the inverter system.

The correct answer is 200 A. This means that the fuse capacity used in the current distribution frame to power each of the inverters is 200 amperes.

The correct answer is R1, R2, and C5. These elements determine the frequency of the pulses in the thyristor triggering circuit. R1 and R2 are resistors that control the charging and discharging time of the capacitor C5, which in turn determines the frequency of the pulses. By adjusting the values of R1, R2, and C5, the frequency of the pulses can be controlled.

The correct answer is "Falla de inversor". This means that the alarm indicator will turn on if the CD input switch is operated in the OFF position due to an inverter failure.

The correct answer is 42 A 56 VCD. This means that the voltage of the power supply for the control cabinet of the systems with priority 9*WAA103B is 56 VCD and the current is 42 A.

The correct answer is "De entrada CD". This is because the sentence states that the switch turns on and off the inverter when operated in the "encendido" (on) and "apagado" (off) positions. "De entrada CD" translates to "DC input", suggesting that the switch controls the power input from a DC source to the inverter.

This circuit is designed to provide a charging path for the capacitors of the DC filters. It is used to pre-charge and start the circuit.

The correct answer is 41 VCD. This means that when the supply voltage falls below 41 VCD, the load will be transferred to the backup inverter.

When there is a fault in the WAA103B (10 KVA) inverter, the fuse that opens due to excessive current is F4.

The correct answer is "Indicador de alarma de falla de inversor" because it is the indicator that is activated when the CD input switch (S1) is operated in the off position, either automatically or manually. This indicates a failure in the inverter system.

The correct answer is "Interruptor de entrada de CD". This is because the given statement mentions that its function is to turn the inverter on and off when operated in the on and off positions respectively. Since the inverter converts DC power to AC power, it makes sense that the switch responsible for controlling the input of DC power would be used to turn the inverter on and off.

The correct answer is 240 Hz. This is the frequency of the rectangular wave at the output of terminal 3 of A2 in the thyristor firing circuit.

L4, C36, and C37 are the elements that provide EMI noise suppression in the output circuit of the inverter.

The correct answer is F4. The Chase-Shawmut A50P500 fuse, with a capacity of 500 amperes, is designated as F4 within the WAA103B inverter.

This answer suggests that the failure lies in the output of the inverter. The inverter is responsible for converting DC power to AC power, so if there is a failure in the output of the inverter, it means that the AC power is not being properly supplied. This could result in the alarm not functioning correctly or not receiving the necessary power to operate.

The correct answer is "Bastidor de Control y Distribución" because it is responsible for governing the operation of the reserve inverter and includes a signaling card. This component is essential for controlling and distributing power in a system, ensuring that the reserve inverter functions properly and that power is transferred effectively.

La tarjeta de señalización PLM-51081 y el circuito con prioridad 5*WAA502B están diseñados para detectar y manejar diversas alarmas. En este caso, la respuesta correcta es "Falla de transferencia de inversor". Esto significa que si hay un problema con la transferencia de energía del inversor, la tarjeta de señalización y el circuito con prioridad estarán preparados para detectar y responder a esta falla. Esta alarma es importante ya que indica un problema en el sistema de inversor, lo que puede afectar la operación y el rendimiento general del equipo.

If there is a total loss of AC voltage to the load, the "Alarma falla de salida" (output failure alarm) will be activated. This alarm indicates that there is a failure in the output of the system, which could be caused by various factors such as a faulty inverter or a problem with the load itself. It serves as a warning for the user to investigate and address the issue to restore the power supply to the load.

The correct answer is 125 A. This is because the fuse for the backup AC connection for the reserve inverter should have a capacity of 125 A.

The correct answer is L1 C4 a C15. This is because L1 and C4 to C15 are the elements that make up the input filter of the CD and their function is to limit the transmission of noise to the battery.

The correct answer is "Indicador CA." The given explanation states that the indicator is yellow and lights up when the audible alarm has been cut off using the ALARM CUT switch. This indicates that the indicator is related to the AC (alternating current) power supply. Therefore, the correct answer is "Indicador CA," which translates to "AC Indicator" in English.

Las conexiones de VCD y VCA deben incluir un fusible de 400A para cada inversor. Esto se debe a que los fusibles se utilizan para proteger los inversores y evitar que se dañen debido a una corriente excesiva. Un fusible de 400A es capaz de soportar una mayor corriente que los fusibles de 200A, 150A o 100A, lo que lo hace más adecuado para proteger los inversores en este caso.

The correct answer is R8. In the firing card of thyristors, the output frequency of the inverter is adjusted using the potentiometer R8.

The correct answer is R4. This is because the sentence states that the transfer adjustment on the A3 transfer control card is done using a potentiometer. Among the options given, only R4 is a potentiometer.

The correct answer is A3 (4864-432-00). This is because the question is asking for the designation of the control and transfer circuit within the WAA502B inverter, and A3 (4864-432-00) is the given designation.

The correct answer is R5. On the firing card of thyristors A1, the adjustment of the shutdown due to low input voltage is made using potentiometer R5.

The correct answer is "Inhibición por bajo voltaje de entrada." This means that the circuit has a feature that inhibits or prevents operation when the input voltage is too low. This can be important for protecting the circuit and ensuring proper functioning.

The correct answer is A8 (4872-257). This indicates that the control and synchronization card in the WAA502B inverter is designated as A8 with the code 4872-257.
