LS3 Adjustment
The LS3 switch is used to open the touchbar circuit, allowing the doors to close once the doors have
reached the full open position. Check that LS3 actuates at approximately 80 to 85% of the full open
position. LS3 must not bottom out. Adjust as required. See Figure 11- 25.
Door Stops and Cylinder Rod Adjustment
Check that the doorstops do not prevent the doors from opening the full 90°. Check that the cylinder
does not prevent the doors from opening the full 90°. The cylinder piston must not bottom out at ei -
ther the open or closed position. This can be determined by either scribing a line on the cylinder rod or
by removing the rod end bearing from the teeter cam. Manually holding the doors open or closed and
manually extending the cylinder rod will determine the amount or remaining stroke. Adjust the length as
required.
Touchbars
Each touchbar has two switches, top and bottom. Check both touchbars four places, one at a time. The
bottom of the touchbar tubes MUST NOT drag or contact the lower bracket. Repair as required.
Components/Hardware Check
Check that all components are secured with the correct hardware and tightened properly. All jam nuts
must be tight. There should be no excessive play or excessive friction between any moving parts, door
shaft levers and bearings, lower pivot bearings, rod end bearings, cam, lock pawl, cylinder, etc. Repair
as required.
Electrical Wiring Check
Check that wire terminations are properly crimped and secured. All wiring must be properly tie wrapped
and secured away from all moving parts.
