Repair Guidelines
Warning:
To avoid risk of serious injury proper precautions must be taken to
prevent the Gate Assemblies from rolling on slopes.
R1: Check for and remove internal obstructions to Gate movement.
Troubleshooting indicates something inside the Gate may be obstructing free opening or closing
movement. Do not operate Gate or damage to components may result. Remove Top Covers
and inspect the inside of the Gate for possible obstructions. Check for and remove excessive
debris from under the Gate. Check to make sure the V-Guide Rollers in the Bulkheads are
properly engaging the inverted angle iron Tracks and that the Transition Rollers are properly
riding on the Guide Rail. If not, reposition the Gate to bring Rollers back on track.
R2: Check and re-tension the Capstan Drive Cable.
Troubleshooting indicates that the Capstan Drive Cable is not adequately tensioned. Do not
operate gate or damage to components may result. Start by removing the appropriate Enclosure
Cover then inspect the Tension Pulley assembly. The extended length of the springs must not
exceed 330 mm (13"). If the springs exceed this length it may be due to a damaged or worn
Capstan Drive Cable or loose wire rope clamps. Inspect for and correct the cause of the loose
cable. Carry out the "Tension the Drive Cable" step in the Product Description Manual to tension
the Drive Cable.
R3: Check for and repair damaged Capstan Drive.
Troubleshooting indicate the Capstan Drive is damaged. Only the simplest Capstan Drive
repairs are likely to be made in the field. Inspect the Capstan Drive for obvious problems such
as a bound Drive Cable. If no field adjustments can be made, detach the Drive Cable and
remove the Capstan Drive for replacement.
