9.1 Start-up
• Check that the supply control voltage complies with the rated control voltage of the unit.
• Check that all electrical connections are done according to the delivered electrical diagrams.
• Switch the power on.
• Check that the hoists control method complies with the application (inverter control or two-speed
control) with parameter 4-8.
• Make sure there is no load in the hook. Run the hoist both directions, slow speed and full speed for at
least five seconds. Check that no messages appear on the display.
9.2 Load measure
Check that hoists Load Measure type complies with the application (Motor or Load sensor in two-
speed control) with parameter 4-7-1.
9.2.1 Load measure type by ”Motor”, (see the parameter 4-7-1)
• Check that the actual load value parameter 1-2-1 shows 0.00t ±10% from nominal load, when lifted
only empty hook, up and down also slow- and fast speed.
• Check that the actual load value parameter 1-2-1 shows x.xxt ±10% from nominal load, when lifted
test load up and down also slow- and fast speed
9.2.2 Load measure type by ”Sens.”, (see the parameter 4-7-1)
• Check that the actual load value parameter 1-2-1 shows 0.00t ±5% from nominal load, when lifted
only empty hook.
• Check that the actual load value parameter 1-2-1 shows x.xxt ±5% from nominal load, when lifted test
load.
When either of the measurements done under step 1 or 2 does not result in the required outcome, the
load calibration procedure has to be carried out. Refer to chapters “Overload protection – Motor
torque” or “Overload protection for load sensor” of this manual for instructions.
When local regulations require a dynamic true overload test, follow the procedure as described by
the local legislation.
When local regulations require a static overload test (110%…140% of rated load of the
hoist), temporarily by-pass the overload function with parameter 3-5 (“OFF”). Be aware of
mechanical restrictions and additional mechanical overload switches! When rated load is
over 110% then hoisting is only possible with slow speed!
Check the function of the installed features.
