9. MAINTENANCE AND ADJUSTEMENTS
•
Inspect the lift occasionally for any looseness of bolts, check cables and clamps. Pillow block bearings
are pre-lubricated and motor does not need attention. If magnetic brake does not hold properly, it
must be replaced immediately.
•
Level corrections are to be made (with screen is mounted) after confirming that the cable is packed
tightly and is straight on the drum.
•
For plasma screens mounted within the ceiling and lowered to a viewing position, level adjustments
must be made at the viewing level.
•
After adjustments are completed, check all bolts and clamps for tightness.
•
Check drum lock solenoid occasionally – see if arm raises during down travel – all other times it stays
in a locked position. If the solenoid does not pull up, the microswitch will not start motor in the
down position. Check the centrifugal cam located on the drum stop block. It should be able to
move freely and will drop when it reaches the top of the drum, this avoiding contacting the arm of
the drum lock. If drum rotates fast, the cam will lock the arm after the first rotation.
