Testing the hoist without load
1.
Check the electrical connections
• Turn on the power to the chain hoist.
• Check that the rated voltages correspond to the main voltage.
• Check that the power supply to the chain hoist is protected with fuses of the correct size.
• Check that the phase sequence is correct.
• Check possible fault messages from hoist monitoring unit and inverters (not in all models).
2.
Check the controller
• Check that the controller is correctly installed and in good condition.
• Check the functionality of push buttons, joysticks, and switches.
• Check that all motions occur to the correct direction.
• Make sure that desired functions occur when operating the push button, joystick, or
switch.
• Check that the hook movement corresponds to the control direction.
• Check that the controller does not cause any disturbance to the functioning of other
controllers.
3.
Check the emergency stop button
• Check the operation and condition of the emergency stop button.
WARNING! UNCONTROLLED MOVEMENT HAZARD
Emergency stopping could cause the product to move or operate in an uncontrolled
manner. Uncontrolled movements or operation could lead to death, severe injury, or
property damage.
Only use the emergency stop button to stop the movement or operation of the
product in an emergency situation.
4.
Check the limit switch operation
• Check the operation of the mechanical or magnetic limit switches.
• Check the operation of the rotating geared limit switch.
Raise and lower the hook at low speed, until the limit switches are activated. When the
limit switches are activated, they prevent further upward or downward movement of the
hook. If the desired function does not activate at the selected position, adjust the limit
switch. If the geared limit switch cannot be adjusted, replace it.
5.
Check the buffers and end stops
• Check that the buffer hits center of the end stop.
• Check that the buffers of the chain hoist are able to bump into the end stops or buffers of
another trolley.
6.
Check the operating sound and movements
