− The parameters are properly set after factory tests and no adjustments are needed except for the
parameters that depend on the application and the motor. Write down in the parameter list all the
values that have been changed.
2.3 Test run without load
− Make sure that movement will not cause any danger to the environment or to the crane itself. Avoid
driving close to the limit areas.
− Check the limit switches manually if possible.
− Check the run commands on the keypad display and correct the drum rotating direction. The arrow
rotates clockwise if S1 (fwd/up) is applied, and counter-clockwise if S2 (rev/down) is applied.
− Check the function of the speed sensor.
− Check the function of the speed supervision circuit.
− Drive forward (upwards) at minimum speed for 5 to 10 seconds. Accelerate to full speed. Run 5 to 10
seconds. Stop. Repeat the same in the reverse (down) direction. Check the frequency display to
make sure that the frequency changes through the whole operational frequency range from the
minimum to the nominal speed.
− Check the motor operation (acceleration, deceleration and braking): accelerate to full speed forward
(up), change to full speed reverse (down) and full speed forward (up) again and stop.
− Check the limit switch functions: drive forward (up) slowly and check the slowdown and the stop limit
switch operations. Re-check using full speed. Repeat the same check for the reverse (down)
direction.
− If the optional ESR is used, check the maximum frequency.
2.4 Test run with load
− Note, three loads are required:
− Nominal load (100%) for normal operation.
− Limited load for ESR (optional).
− An adequate extra load for dynamic overload testing and to test the ESR load limit.
− See the maintenance instruction HU1.03.0004 “Erection, Installation and Testing of EOT cranes” for
the details of the load tests.
– Make sure that movement will not cause any danger to the environment or to the crane itself.
− If the optional extended speed range (ESR) is used, check that the load limit is correctly set and
hoisting with bigger loads is prevented.
– Drive in both directions at minimum and maximum speeds.
− If the fan tube resistor unit is included, check that the fan(s) starts to blow when driving down with
nominal load and continues to blow for about 4-5 minutes after stopping.
2.5 After the test run
– Record all the parameter value changes in the parameter list.
– Make sure all remarks and setting values are recorded.
