With this parameter the rotating field power is recorded according to a defined procedure for both the slow and fast lifting speeds. The procedure occurs in two steps. In the first step, the rotating field power is measured with empty load hook and in the second step with a test load. The LIS-SE uses these values to calculate a proportional function (load line), which in turn is used in later operation to calculate the respective current load from the rotating field power.

All subsequent steps must be completely carried out, since otherwise the setting is not completed and error messages can arise!

Note

To set the test load, a test load with known weight is required. The test load should be 80% of the maximum load capacity.

The test load must be at least 40% of the maximum load capacity. If a setting is made with a test load between 40% and 80% of the maximum load capacity, this must be noted in the test log book.

The closer the test load is to the maximum load capacity, the more accurate will be the displayed weight of the load.

Tip:

Several measurements are carried out in the following. After each measurement, the load hook can be lowered so that there is enough lifting height available for the next measurement.

Entering the value of the test load:

   Select parameter P 2.3 with the arrow buttons.

   Press Enter briefly

●   The parameter is opened.

●   Load is displayed.

   Hold Enter pressed until “0.000” is displayed.

   Enter value of the test load with the arrow buttons.

   Press Enter briefly.

●   The LIS-SE displays “Pro1”.

Measuring rotating field power without test load:

   With slow lifting speed, hold “Lift” pressed until the hoist motor shuts off automatically.

●   The measurement of the rotating field power at slow lifting speed has been performed.

●   The LIS-SE saved the value.

●   The display shows “Pro2”.

   With fast lifting speed, hold “Lift” pressed until the hoist motor shuts off automatically.

●   The measurement of the rotating field power at fast lifting speed has been performed.

●   The LIS-SE saved the value.

Measuring rotating field power with test load:

   Lower load hook.

   Attach test load.

   Lift test load until it is hanging freely.

   Hold emergency stop pressed for at least 5 s.

●   The LIS-SE displays “Pro3”.

   With slow lifting speed, hold “Lift” pressed until the hoist motor shuts off automatically.

●   The measurement of the rotating field power at slow lifting speed with test load has been performed.

●   The LIS-SE saved the value.

●   The LIS-SE displays “Pro4”.

   With fast lifting speed, hold “Lift” pressed until the hoist motor shuts off automatically.

●   The measurement of the rotating field power at fast lifting speed with test load has been performed.

●   The LIS-SE saved the value.

Note

The LIS-SE switches to the mode for measuring with test load and 0.000 is shown in the display.

Checking the value:

   Lift up the test load and hold “Lift” pressed in fast lifting speed until the hoist motor shuts off automatically.

   Set down the test load.

   Compare the value of the test load with the display on the LIS-SE.

The value is allowed to deviate up to ±10%. Otherwise the measurement must be repeated.

   Call up the parameter level.

   Exit the parameter level with parameter P 9.9 to confirm the settings.

   Press “Lower” for approx. 2 s to conclude the setting.

●   Teach-in is completed and the LIS-SE is ready for operation.
