Utilize the following steps to correct hoist motor phasing:
3.
Interchange any two lines supplying power to the hoist.
4.
Re-energize power supply to the hoist.
5.
Check the hoist travel direction for correct hook motion by pressing
UP
on the hoist control device. If the
direction of the hook travel matches the direction marking of the hoist control device button activated then
the hoist motor is properly phased. If the direction of the hook travel does no match the direction marking of
the hoist control device button activated the hoist motor is improperly phased and must be corrected by
repeating steps 1 through 5.
ii.
If the hoist has a motorized trolley, check that the trolley travel motion matches the direction
marking of the trolley control device button activate.
-
MOMENTARILY
activate one button of the trolley control device and observe the direction of
trolley motion. If the direction of the trolley travel matches the direction marking of the trolley
control device button activated (example, the trolley direction is EAST when the trolley EAST
control device button is activated), the trolley motor is properly phased. If the direction of the
trolley travel does not match with the direction marking of the trolley control device button
activated, the trolley motor is improperly phased and must be corrected.
DO NOT
use the
trolley until motor phasing is corrected.
DO NOT attempt to correct an improperly phased hoist by changing
the wiring in the hoist control device or the hoist contactors; or by
changing the markings on the hoist control device.
DO NOT
attempt to correct an improperly phased trolley by changing any wiring to
the trolley control device or at the trolley contactors; or by changing the markings on
the trolley control device.
DO NOT
operate the trolley if direction of the trolley motion does not
match the direction marking on the trolley control device button
activated.
1.
Disconnect the power, lockout and tagout the power supply
before working on the electrical wiring to prevent accidental
application of power.
2.
Only a qualified person should disconnect or connect the power
lines to the hoist.
