            Lite: A single uninsulated piece of glass

Procedure

On the cockpit computer, using the lisec batch sticker (the sticker under the header sticker) select the correct batch on the left-hand side of the screen.
Once the batch is selected, check the sizing of the first and last stickers in your sticker run, verify they correspond to the first and last items on the computer batch.
Check your header sticker for what spacer size is needed (see AMSCO Production Sticker).
Place the header sticker and the lisec batch sticker (the first two stickers in the run) next to your keyboard and give the rest of the glass stickers to whoever is at the grid station.
While dropping off the glass stickers, check what spacer size is currently loaded into the machine.
1. If the spacer size called for on the stickers does not match the current spacer loaded, you will need to change the spacer to the correct size (see Lisec Spacer Changing or VSA book 9.15 change spacer page 148. Version 2021,08,13 2/12/21)
Check if the low-e glass lites have been edge deleted.
1. If they haven’t been, stop and edge delete them before continuing (see Edge Deletion)
Start by loading the clear and then low-e lites of glass onto the machine
1. On lites with Low-e, OBS, Glue chip, or Hard coat load the lite with the Low-e, OBS, Glue chip, or Hard coat facing out.
2. Check the sizing of the length/width of the glass lites with a tape measure.
3. Orient the glass so that whatever is longer out of the length/width is placed horizontally on the machine.
4. Check low-e with a low-e tester.
Push the manual button (the button with a picture of a hand on it) on the PLC-1 control panel.
Clear the preexisting run data by holding the stop (f8) button and then pressing the homing button.
Press the Auto and then start button on the PLC-1 control panel.
On the cockpit computer select “OK” to the alarm prompt and then press the green check mark on the bottom right of the screen.
Once the lites have been loaded onto the machine, a sensor will trigger if the clear and low-e units have been loaded out of order.
1. If they have, a prompt will appear on your computer screen asking you to either bypass the sensor or correct the issue.
When the lites reach the spacer applicator (VSA), a sensor will scan the lites to ensure the correct orientation of the units.
1. If the units are oriented incorrectly, a prompt will appear on your computer screen asking you to either bypass the sensor or correct the issue.
When the lites reach the FPS station, place the glass sticker on the bottom right corner of the clear lite.
1. The sticker should be placed 2” down and 2” in from the bottom right corner of the unit.
While at the FPS station, read the glass sticker checking for any of the following options: Hard coat, Tempered, wildfire, breather tube, grids, overfill.
1. Apply hard coat sticker, tempered sticker, and wildfire sticker to corresponding units.
2. For overfill units, follow that unit to the LVL1 (hotmelt applicator), and turn on the overfill skip setting, prior to the unit being sealed.
3. For grid units (see Lisec Grid Guide)
4. For breather tube units (see Breather Tube Application)
After addressing the glass options appropriately, check the sticker for glass sizing and double check the sizing is correct.
1. Use the built in tape measure to check sizing.
Check the application of mylar tape (on the bottom righthand corner of the unit). If the tape has not been applied correctly, adjust it accordingly.
Check the RTV screen for any computer detected defects in the glass.
1. Remove any units that are outside of AMSCO’s glass tolerance specifications (see Glass Tolerance Specifications).
Press floor foot pedal to disengage the blue overhead light and allow the unit to proceed to the FPS U station.
Once the hotmelt has sealed the unit, check the bottom left, top left, and top right corners of the unit for any voids or excessive hotmelt.
Use your green silicone pinch pad to eliminate voids and excessive hotmelt.
Take the unit off the machines line and place it into a harp/rack.
1. Placing the unit in the harp/rack so its 4^th corner is exposed.
2. For large units. Us the manipulator to offload onto a rack (see Glass Manipulator)
Check the 4^th corner for any voids or excessive hotmelt, use your green silicone pinch pad as needed.
Check the completed unit with a low-e tester.
Check the overall quality and cleanliness of each unit you offload.
