Controllers for web monitoring

We talked about this tools icon here and one of the common questions that we get asked is is it possible for us to lock the screen so that only people who have privileges to access that have access to it and we can do that in our password screen right here. This password screen allows the operator or the power user to lock certain parts of the controller so that the access is restricted to those who are familiar and knowledgeable about what the consequences of the changes would be. So there are two main user levels. This one on the top is what we call as an operator level axis.

This would be any operator that needs to change certain things with respect to the controller including setting up the sensor. If you want to do line guiding, contrast guiding or pattern guiding, all of those are available to the operator through the operator screen. If I click on that, you can see the things available for the operators to change. Again, setting up the sensor.

If you're doing width measurement, you can look at the different width measurement options that we have. We'll go into detail about this in a later video. And then the next level of access we have is the power user. This is somebody like a maintenance professional or anybody involved in commissioning our system.

Most of the functionalities here are one-time kind of things that you need to do when you try to install the system for the first time. So again a setting related to the actuator some other high-level sensor related settings controller options and communication if the customer wants us to enable or disable certain access levels we can do that and that's available in the power user to be able to do it. One of the questions that we get asked all the time is how do you know when a password is enabled or not? As long as you see these icons, that means that the passwords are not enabled.

If I go in and enable the password on the operator screen, then that icon has disappeared. So, you won't be able to have access to that unless you enter the operator password. Likewise, if I go in and lock the power user screen, we won't be able to see the the icon for that. Nobody would be able to enter it unless you enter the password.

That's essentially how you would enable and disable the password. [Music] If you want to change the password, there's an option to change the password. All you need to do is pick the password you want to change. Let's say the operator or the power user.

You would click that, enter your current password, and then change it to new password. So, the passwords are fourdigit long. and please contact the factory to get the default password information. Once you have the default password, you can go in and change the password for the operator screen and the power user screen.

But please note that once you change the password, there's no way that we would know what the password is. So, we wouldn't be able to recover that unless you send the controller back to us. So, that's essentially what this password screen is. [Music]

one of thing that happens when we put the web guide in automatic mode is that this pools icon is going to disappear um I'll do that and you can notice that the proven automatic the tools icon disappears so essentially when the web guide is in automatic mode the operator cannot go away and change any parameters related to the edge Center or contrast or anything related to the speed the G none of those parameters could be changed while the webite is not attack just a safety just so that we don't intentionally cause any cor when the webc isn't on so that's what that one is the only screen that the operator can navigate to is going to be this screen and that's going to show you the actuator position in a bigger view the operator cannot go into any other screen while in automatic mode the other thing that you're going to notice when the web guide is in automatic mode is take a look at these sensors when I put it in automatic mode the buttons so those buttons are disabled again same idea when you are an automa we don't allow the operator to change the orientation of the sensor so if they can't enable or disable the sensor they cannot switch from one sensor to sensor all of these things have to be done a pror before they put it in the automatic one and then again reset G point if you put it in automatic mode that disappears so they won't be able to make any big adjustments to the gate point the only exception to that is to reset that gate point to zero as the only thing that they can do and that's the reason why we say that when you do a reset gr point to zero and be really careful um and do only when you needed and that's the reason why we have that accept button so if somebody presses that by the St we don't necessarily have to take that command unless the operator intentionally presses accept if it doesn't press the accept button then it go back to the previous gr point

one other thing that we have is basically this actuator position bar if you press that motor icon on the hle this let you see a bigger view of the aurator position K in this case if the web tag moves back and forth you can see that actuator bar will move back and forth one thing to note about this Servo center button is that this has a different functionality than what it is in the home screen so we recommend that you take a look at the subsequent videos about this functionality before using this

everything that the operator need should do on a day-to-day basis can be done from the home screen for example things like putting the web guide in automatic or manual jogging the web guide back and forth and then putting the web guide in the symol center mode the first and foremost thing with with regard to the actuator is this actuator position bar this bar is going to indicate the position of the actuator and this position is the electronic position that is being read by our driver right now the actuator is in the middle as we jog the web guide you should see that actuator position to be changing and then there's also visual indication of when the actuator is getting near to its extreme position and that's indicated by this um yellow and then if you keep moving it turns red which means that there's really not much left in the actuator position so this is indicating that it's reaching its stroke Lane now in terms of the stroke of the actuator these are all electronic limits that we have in the controller in subsequent videos we will talk about how one can change those limits based on what the actual actu stroke T takes like that so this is the J if I press this one you should be able to see that go J left and it'll do the same thing if it goes to a certain position where it's getting closer to its extreme it's going to be yellow they keep going let SC the get red and then if it's off the screen even if the actuator presses this button um nothing happens and that's because the actuator is reached this limit there so it will not move in that direction however it will move in the other direction so that's the actuated position more then we saw the jog left and J right command there

so what we have today is our SCU 6X controller this is SCU 6X MD and we have one sensor connected to it then in the motor port we have an actuator connected to it right there seu 6X MD and there is another option SCU 6X mxd both of these options are allowing us to connect different thrust actuators for example this particular one Su 6X MD has the low thrust option where we have an actuator that can drive up to about 300 lb force of trust anything related to intermediate web guiding this will be the actuator for that this particular actuator can draw up to 4 amps of CCT when we go to a higher prust the part number is going to be a little bit different it's going to be s use 6X mxd where the X relates to the extra in that we need and that particular one can drive up to about 500 lb of thrust so a shifting stand with the total weight um of no more than about 5,000 lb can be driven with that actuator the only difference would be the connector here would be a little bit different on this side now it'll be a high thrst a high current connector and then for that particular actuator we would also need a different power in the Dual rear power input will have 7 amps up to 7 amps for that we also can do up to 48 H VC

okay this is about moving the actuator manually to facilitate loading and unloading the r but the real thing with our system is basically it does guide the web automatically to its desired position so just to show you that let me present the web put the web guide in automatic mode so as you remember that the gray bar in the middle is basically our G point and if we are on one side of the G point the actuators will move one way if we are the other side of the G point the actuators for to M be away and it's that's out it's stting the we and then the actuator position bar indicates what the stroke of the actuator is and obviously once a r it stroke it doesn't matter how much eror we have the accelator is not going to move in that direction but if the eror is f on that direction then the aurator is for Mo and you that in for BL so this is the automatic feature of our web guing system and right now I'm using a single edge to gu the material and it doesn't matter if I have one Edge or two edges it will do the same thing

so the next thing that we're going to look at is we showed how to do Edge guiding with a sensor now we're going to do how to do Center guiding with the sensor so I'm going to change this orientation sensor orientation so that sensor one can detect voltages of the web and that's what it it's detecting and as you remember from our previous video when we do Center gu and the GU the reference for the web is not based on one Edge actually based on the two edges so that's what is presented by this green bar so if I move the center line of that web to this green bar to this point box act and then put it an auto then when that Center Line changes position that's how we're going to guide it essentially s guide so what is the advantage of Center guiding is that when you hand weight changes you don't have to move the sensor as long as you get Point offside is the right location so for example if I put another web that's wider you can do a on the Fly Wick change with one to another web Wick and it will automatically guide and either one in a SLE L position and that's one of the biggest Advantage with a center diting solution is that when the wit changes let's say it have some variability in your Bri your web will always be presented to the center line of the machine as long as the center as long as the sensor is set up properly then you can bring it to that Center Line position with respect of the quadr or half an inch we with so in terms of Center guiding Center position is represented by the green bar and then the web guide is going to keep that Center position um I'm moving the actuator back and forth so that green bar aligns with that gray gray T point and preference as it should so that's the main difference between Edge guiding and Center Tiding again you still have that option of web break so the web braks it will stop actuating and it will start back actuating when the web is stressing and then obviously it's going to do it it's going to stop until the web reaches its B Point reference if the WID ches doesn't matter that's long red W the center line set so that's Center D with with a single sensor

now there are situations where you are guiding the web you got it at the part but you want to make a fine adjustment and with the traditional sensors there might be something like a micrometer and an operator needs to reach in and try to adjust that screw on the micrometer to move it back and forth to do what is called as a fine day point adjustment so think of it like a lamination process you got the wind allign guiding but you want to change that gide point just a little bit you don't want to make too much of an adjustment and you want to do that while the wind is running and that is what we call as a fine G point adjustment how to do the fine gate point adjustment right now the gate Point offset isus 119 mm and if I want to change that just a little bit then I if I want to increase that I can press that increases that the web gate is not going to move until it goes away from B so just to illustrate the SP thing now it reach the limit for the dead man and it's continuing there that's our fing G point adjustment so this allows you to be able to Mike uh make very fine adjustments to the guide point again the plus arrow allows you to increase that g point and minus Arrow allows you you would decrease that g Point that's what is called a fine G point adjustment and this adjustment can be done only when we are in automatic mode and then each press of that will take1 mm I think that's what it looks like1 mimet to move the gate BL

okay one other feature in terms of resetting the G Point how that we have is there are some occasions where you want to reset it to zero and this has to be done with extreme care and only people who know what they're doing should be able to do this and that's because this is very powerful and changes the G Point immediately so there might be some loation where you want to absolutely reset pick 8. to0 the best way for us to do that is while it is in a Ned did you press the servo center button it's going to show you that hey you want to reset the G point to zero do you want to accept it obviously if I accept it the web isit a different location it's going to go all the way to one side the actuator is going to go all the way one side because it's trying to correct for the web position again when you're in automatic mode if you press this Servo center button then it would allow you to reset the T point if I press accept the T point is going to be in the middle now basicly the actuator is newly because it's trying to bring the we toward its um to the gr Point reference that's the way in which you could reset the G point to see

okay in our previous video we looked at the guide point offset basically how to reset the G Point again that is useful when you have a white sensor and you uh present the web like different locations so just to go over that one more time here I've got a white sensor here and the web is positioned at some point I'm going to go in and reset great Point except up there and if I put the we p in automatic it's going to stay in that position and if I need to change that date point to a new location when it's in manual and we can still do that the web isit this new location and I'm going to do the reset cway accept and when I put it in Auto in SC the actuator is staying in position because the web is at the point location and if I move the web to one side part the other it's little stop it's going to die with respect to that and that's the re cway
