DUAL SPEED DIRECTION CHANGE
Once wiring is correct and when you push slow the hoist moves in each direction slowly
then momentarily test the fast, if the hoist continues moving in the same direction in fast
as it did in slow then you have completed the trolley wiring successfully, however if the
fast speed suddenly changes the direction that the hoist was travelling when in slow you
need to go the trolley terminal strip and swop 2 phases on (
U2 )
Locate the electrical panel
of the trolley motor.
1. Remove the cover.
2. Inside you will find 3 black cables, crimped together and 3 red cables crimped together.
These must be left crimped together if the host and trolley are running on 460v.
3. There are 6 cables already connected to the terminal strip from trolley’s motor. A set of 3
red cables and a set of 3 black cables.
4. Feed the short cable coming from the trolley’s contactor control box into the motor panel
following the diagram above.
5. You can now power up the trolley and test the directions.
NOTE:
Depending on the factory’s order of the trolley motor wiring, you might find your fast and
slow speed’s directions are swoped. This can be simply corrected by changing 2 cables.
Example: take V1 and W1 and swop them around.
