SECTION 2
INITIAL START-UP
WARNING
Before connecting the hoist to the power supply, check all
“motion” buttons or selector switches on your controller or push
button station to ensure that none of them bind or stick in any
position. Check pendant or controller cables to ensure that they
are not damaged and are wired to desired hoists.
Once power has been supplied to the hoist, several important no-load checks must be made.
Proper Hook Motion (Hoist Motor Rotation)
Since rotation direction of any three-phase AC motor can be changed by reversing any two of the
three lines feeding the motor, it is important that the direction of motion is correct with respect to
the button being depressed, or the selector setting.
To check/correct hook motion (motor rotation),
carefully
inch the
up button
and observe hook
motion. If hook does not travel up, stop the hoist and open the main power source disconnect.
WARNING
Do
not
attempt to reverse hoist motion by changing control leads
in the push button, controller or at the contactor, and do not
change the nameplate on the P/B. Safety switches of the control
circuit wiring as furnished from the factory are directional
sensitive. Changing the push button control leads, wiring inside
the controller or nameplates will prevent the safety switches
from functioning properly. This might create dangerous
situations.
IMPORTANT
Do not run the hoist with the DOWN button if direction is
reversed. To correct the direction of the hook block travel,
reverse any two leads supplying power to the controller, at the
main power source or at the lead in connections to the hoist. Do
not change the internal wiring of the hoist nor the controller.
