CHECKS
Before reinstalling the top cap and front panels,
an operational check should be completed on the
internal tower safety features.
Verify that the ACME drive screw is
lubricated.
Ensure all unnecessary jumpers are removed
from the Trailing Cable and AC Controller
connectors.
Verify that the shipping bolt was removed
from the cable tensioning pulley and that the
pulley is hanging in the tower without hitting
any obstacles during platform travel.
Apply temporary power.
Verify that the E-Stop is functional with no
lift movement.
Manually depress the final limit switch (the
highest positioned switch) and verify any
travel of platform is prevented.
Harness should be removed from the
trailing cable to simulate safety nut switch
activation.
Manually depress the safety nut switch (the
switch near ACME nut) and verify any travel
of platform is prevented.
While lowering the platform, lift the Safety
Pan under the platform to confirm it stops
travel in the Down direction. Travel in the
Up direction should not be affected.
Manually depress the Over-Speed Governor
(OSG) switch (the switch at the bottom
of ACME screw) and verify any travel of
platform is prevented.
If equipped, lift the float of the float switch
(the switch at the bottom of the tower) and
verify that DOWN travel is prevented.
