Run and Verify Hoist Electrics and Data

Verify Proper Wiring
Verifying the wiring for the three-phase power receptacle is important to ensure that the hoist
will properly respond to controls. If you are installing a 120/208 V hoist, you can use the Prodigy
Phase Checker (ETC part number 8055A4013). For 277/480 V hoists, use a standard three-phase
checker that is rated for 480 VAC, similar to the 480 V phase checker you can purchase through
ETC (part# M7639).
1. Plug the Phase Checker into the three-phase receptacle that will provide power to your
hoist.
2. Look at the LEDs on the back of the phase checker.
•
If the green LED is fully illuminated, the proper wiring is confirmed
•
If the red LED is fully illuminated, have a qualified electrician swap the supply voltage
wires going into the receptacle until the phase order is correct and the green LED is
fully illuminated.
3. Once you have confirmed proper wiring, plug the hoist power and data connectors into
the FlyPipe PCD.
If neither LED is on, either one phase of the feed is not connected or a true 208 V or 480 V
three-phase supply has not been used. Contact a qualified electrician to connect the proper
supply.
Verify Hoist Is Not On Overtravel Limit
If the hoist has shipped with the drum positioned on the overtravel limit, the hoist will not move
when you first attempt movement. If this is the situation, you need to press and hold the
OVERTRAVEL override button for 10 seconds (the Power LED will blink) to allow for movement
off the overtravel limit.
Verify Hoist Motor Orientation
In addition to checking phases at the PCD, you
should also verify that the hoist is moving
properly by viewing the encoder wheel within
the motor box as you momentarily operate the
hoist. When moving
up
, the encoder wheel
should rotate in a
counterclockwise
direction.
If the encoder wheel rotates in the clockwise
direction, release the control button
immediately to avoid any potential damage to
the hoist. Once the hoist is stopped,
disconnect power and verify the wiring at the
three-phase receptacle. If the wiring is correct
and the encoder is still moving in the clockwise
direction, contact ETC Technical Services for
assistance.
