Ktu H2 1

Once the new one is replaced, we need to do the operation in the LMI. So as you can see, this time the operation, we replaced the whole AVR cubicle. So the important item is the high-pace, the regulator, AVR. These two, we have channel 1 and channel 2. They are the redundant design. If one channel fault, it automatically switch to another channel. It can still running. We need to describe the details of the hardware or not. We have several boards, like PTC board, application board, excitation board, CPU, power supply board, and DIDO board. All these are redundant. The two channels, the program is the same. Every hardware is the same. All the programs are in these two boards. And the connectors are the same. The other thing is just the common item, MCB. Maybe in the future, you can put the label, MCB for what. It's easy for your operator to understand. And these are the power supply for the electrical electronics. And there is a switch for the communication switch. This is the switch for the RS-455. RS-455 is the switch for the VLAN. Mr. Ho has already introduced these two modules. This one is for the pulse selection. It selects the pulse from channel 1 or channel 2. And on the door, we can see, we don't have too much action. We have 2 meters for the generator voltage and the generator current. And the HMI, we introduce later in detail. And this emergency button is just for test. Normally, you don't need to press it. And on the door, we only have two buttons, the power button and the app. And this emergency button is just for test. Normally, you don't need to press it. Wait, let me stop here. This button, let me ask Mr. Ho clearly. When you press this button, let's say it's an emergency. When the machine is running on the test mode, when the machine is running on the test mode, it will be a negative, right? It will be a negative MCB. And when it's running on the test mode, this button will not be active, right? It's just for test, right? Let me explain to you. This button is for the test mode. When the machine is running on the test mode, it will be a negative MCB. And when the machine is running on the test mode, this button will not be active. Because... Because it's related to the operation of the machine. Because... When the ZCB is closed, if the ZCB is not open, the FCB is not open. It's related to the operation. And this signal, when we take the button, we have one signal for the internal chip sent to DCS, right? It will also send by the WD08, excitation chip. Excitation chip including this one. It also sends a chip signal to the system of the machine. But at the moment, the machine has not responded to that signal. Can we press it? Later we can close. Let's test it. If the ZCB is closed, no problem. This one is not sent. But I can modify the program. If we press this one, we have the external chip. External chip, yeah. DI, DI, DI. Go to DI. External chip. ZCB out there. When I press this button, at the moment, on my DCS, it still sends one signal. You can see on the screen, external chip. If it is in the test zone, according to the initial design of the machine, like my machine, there is no case that the external chip is sent to the ZCB. So right now, the output of this machine is being played there. I don't have to send the ZCB signal to DCS. If the ZCB is closed, the external chip is sent to the ZCB. But if the ZCB is not closed, the ZCB signal is sent to the ZCB. This is the DI. When I receive this DI, the motor path signal will be sent to the ZCB. Yeah. According to the logic of the machine, there is no case that the ZCB is sent to the ZCB. If the ZCB is closed, the ZCB will be sent to the ZCB. But there is no case that the ZCB is sent to the ZCB. There is no case that the ZCB is sent to ZCB. It's because of the design. When they put the gun in, it's just a test. It's just a test. When it doesn't go down, it goes up. You have to cut it close. Okay. We have nothing. Wait. You are... Sending over... No, no, no. That's in details. Push. Second, put it up. Two verts. We have installed our AC rc slubber including a fuse holder and three diodes, two capacitors and one resistor. Four resistors in serial connection. In normal operation, we observe the temperature is about 150 degrees. In this case, the temperature is 300 degrees. According to the manual, the temperature is 300 degrees. In normal operation, the temperature is about 150 degrees. Yesterday, it was 170 degrees. My gun was 170 degrees. If I had a different gun, it would be easier. These are synchronized transformers. One for each channel, for each high-pace. It's a renowned design. That's all for the bus. SCR. We introduce one SCR because three are the same. We have installed a temperature detector. It detects six serrestrial temperatures in a sequence. One, two, three, four. We use a thermometer to measure the temperature of the bridge. This thermometer will measure the temperature of six... The fourth channel. That's right, the fourth channel. And six capacitors. Each of these will send a signal to the alarm system. What is the alarm setting now? Alarm only. 70. Alarm degree. 70 degrees. This is the most famous one. It only needs one channel. Yes, that's right. Each channel has a limit of 70 degrees. It will send an alarm. It only sends an alarm. Not a chip. So it will send it to the computer room. There is an alarm in the computer room. Alarm temperature. If you receive this signal in the control room, maybe you should come here to check what happened. What is the temperature? If you receive an alarm in the computer room that tells you the temperature of the bridge, you should come here to check it. Each capacitor has a limit of 100. 100. 6 of them. One filter and one capacitor. Yes, one filter and one capacitor. It will send it to the control room, right? Yes, it will send it to the computer room. Let me introduce you to the computer room. That is LG6X. It's our pulse amplification board. It gets the pulse from that pulse selection board. And then it amplifies. The output goes to the sequencer. That is the LG6X transmitter. In the past, our company had a set like this. A white set like this. And a black set like this. We replaced all of them with this set. It connects directly to 6 filters to amplify. This is to adjust the volume. To amplify and adjust the amplitude of the filter. Yes, that's right. This is our new set. Yes, this is our new set. In the past, we had a set like this. LG6X. And you can see there are five wires near to the board. This is for controlling the pulse. If there is a relay, we have three wires to control the relay. On and off. And two wires for feedback of this relay. Is to control the, we know the bridge is on or off? Not yet. Wait, what do you want to do? We want to see if the relay is off or not. We will send a signal. If the relay is off, then the power supply for the pulse will be cut. If the relay is off, then the power supply will be cut. If we have a trip signal, the trip signal will activate the relay of the old terminal and the contact will also switch off the bridge. Not only from high-pace, high-pace can control on and off and also the external trip signal can directly switch off the bridge to cut the pulse. If there is any problem related to the trip signal, it will send a signal to cut the bridge. I have one. Maybe you should... I see. Yes, I see. And this fan switch is stuck. Where is it? Next to the maintenance. This fan switch is stuck. This one? Yes, this one is stuck. This fan switch is often stuck. It sends the wrong signal. When it's off, it has to go down. That's right. It's too high. The lower terminal is too high. Try this one. This one is too high. Maybe we need some lubrication. Yes, next one. Yes, we go back to see.
