6.0 CHECK REGISTER
6.1 HALF - YEARLY CHECK
Half-yearly, the following checks have to be carried on:
-Check if rolling up and rolling down is working properly, without frictions or
decelerations.
-Every six months (estimated 300 cicles) grease the 4 brass guide shoe (see.
par. 2.1) using white grease PTFE (Wurth HHS grease or equivalent).
-Check with the end user that projector lift and projection screen (if this is the
configuration) operate in different times (not at the same time) and that while
the first one is operating, the other one is not in power (switcher has to be a
deadman switcher or domotic system that works with this logic).
-Check steel cables covered by black PVC – no steel wires have to be visible
outside the black PVC scabbard.
-Check of the ceiling fixing brackets of the projector lft.
-Check that the end stops are set properly, so that in the rolled down position
(projector lift completely open) it remains at least 3 turns of steel wire onto the
roller tube.
-Check that bolts on the bottom ends of the steel cables are tightly fixed.
-Check that screws that fix projector to the projector lift are tightly fixed.
-Check safety devices – see chapter 3.2.
The result of every half-yearly check has to be sent via Email to
program.maintenance@screenint.com, indicating projector lift model, serial
number, check date, first and last name of the engineer in charge for carrying
out the check.
