00:00Assalam-o-Alaikum, there are many videos of E7 on our channel, you can go and visit them.
00:10But every problem has a new solution, a new fault.
00:17There is a reason for which the E7 error occurs.
00:21Now this is our kit.
00:23In this, the E7 error has come.
00:25They sent the E7 error.
00:27Now I will show you what happened in it and what they tried to repair it.
00:33But it could not be repaired.
00:35Then they sent us this kit.
00:37You can see it.
00:38Check that we could not repair it.
00:40And the E7 error is not being removed in it.
00:44When you see that they have removed the complete repair of it many times.
00:49And many things have been done to it.
00:52But it could not be fixed.
00:54Even when it came to us, the main thing in it was that the voltages that are made here.
01:00I have told you in many videos that the 5 and 15 volts should be made on this jack.
01:10As it is mentioned above it, you can see it.
01:14There is a center ground, there are 5 and 15 on one side.
01:17Although the voltage was not made on it, but we have fixed this voltage.
01:22But despite this, the E7 error is still there and it is not going.
01:28Today we will tell you that if such a problem occurs, then what is the problem and there is no need to worry about it.
01:36Do not waste too much time on it.
01:38I will tell you the situation of it easily.
01:40What is the situation of E7?
01:42We will check it.
01:44We will make you check it with DSO.
01:46Look, it happens that the error of communication from here to there has to be checked by the coupler from both sides.
01:55I will try to make you understand all this and tell you.
01:59Look, first of all I ground the DSO here.
02:02And when I put it here, I have to give it a current of 220.
02:07Look at this.
02:09When you have to see on DSO that DSO is here and DSO is here.
02:13Look, I put it here.
02:15Now, when I put it here, it is not showing anything.
02:23Like here, it is not here.
02:31Look, when I put it here, it is here of this coupler.
02:36When I put it here, look at this AC voltage.
02:40This AC pulse is being made.
02:43This AC pulse is being made.
02:44It means that the one outside from here is giving us.
02:47And look, it is not blinking the light.
02:49That's why I put it here.
02:51Now, this is the other coupler we have.
02:53Look, I have another coupler here.
02:56Now, I will attach it with this and show you its pulse.
03:00How the pulses are generated in it and what happens in it.
03:05I will give you all its information now.
03:13Look at this, if you check in the kit, then I can show you here.
03:18Look at this, below it.
03:20Just a minute, let me check its pulse.
03:24Look at this, I have removed the jack here.
03:27Now, its pulse is not coming here.
03:30Look at this.
03:31This relay also turns off.
03:32Look at this, I will attach it now.
03:34As soon as I will check here.
03:36Look at this, you have to check very carefully.
03:38Check this meter also.
03:40Look at this, it is coming from here.
03:42Look at this.
03:44Its voltage is being generated here.
03:47My pen is not working properly.
03:50It is not working properly here.
03:52And here it is.
03:54Look at this.
03:5615 voltage.
03:57Okay.
03:58And both of its 5 voltages are being generated here.
04:00Now, the main problem is that here, its pulse is not coming here.
04:08Now, I will attach another kit and show you.
04:11So, there is no issue of voltage.
04:14Its voltage is complete.
04:15Everything is complete.
04:16But what happens is that it is not turned on here.
04:19Here, the coupler does not have a pulse.
04:22Voltage comes.
04:23I will check the voltage also.
04:25Voltage is also coming here.
04:26But what is happening here?
04:27The problem is that the pulse is not coming here.
04:30We have checked the pulse from the DSO.
04:32I will check it on the other kit also.
04:34You can watch my video again by backing it.
04:37You can watch it by checking it again.
04:39And here, both the lights are also on.
04:43There is no communication.
04:44I will attach another kit and show you.
04:47The main thing you have to see in this is that how the pulse was coming when I checked it earlier.
04:52And how it is coming.
04:53I will show you its diagram also.
04:56Now, we have attached another kit.
04:58This is the first kit which we have attached earlier.
05:01Okay.
05:02Now, we have attached the second kit.
05:03You have to see that there will be immediate communication.
05:06And I will show you there.
05:08You can see that there are two couplers here.
05:12You can see that.
05:13You can pass the camera and show it to them.
05:15There are two auto couplers here.
05:17Okay.
05:18You can see that the mark which you can see here.
05:21The pulse has to come here.
05:23Okay.
05:24Here.
05:25On this.
05:26This is its number one pin.
05:27Number two.
05:28Number three.
05:29Number four.
05:30Okay.
05:31This is the way of the pin.
05:32The pulse has to come here.
05:33Okay.
05:34This is the way of the pin.
05:35This is the way of the pin.
05:36This is the way of the pin.
