If the LIS is faulty, it must be replaced.

Note

When replacing the LIS, note and compare the operating voltage of the crane and LIS.

The LIS can be damaged by an incorrect operating voltage.

If the LIS is in standby mode:

   Press Enter briefly.

●   The operating hours are displayed.

In operating mode “Lift” or “Lower”:

   Press “Lift” or “Lower”.

●   The current value of the operating hours counter is shown on the display for 3 s.

   Note down the operating hours.

   Only with load population recorder:
Note down the value from the load population recorder. See P 5.2 Load population recorder.

   Note down the values from the parameters P 2.1 and P 2.2.

   De-energise the crane.

   Detach the bush multipoint connector from the pin multipoint connector of the LIS-SE.

   Pull the LIS-SE from the top-hat rail.

   Take the LIS-SE out of the hoist panel.

   Insert the new LIS-SE in the hoist panel.

   Push the LIS-SE onto the top-hat rail until it clicks in place.

   Insert the bush multipoint connector on the pin multipoint connector of the LIS-SE.

   Switch the crane on.

   Only with load population recorder:
Enter starting value under parameter P 6.1.

   Transfer values from the parameters P 2.1 and P 2.2 into the new LIS-SE.

   If the values cannot be adopted, a zero point adjustment must be performed. See Entering default settings.

   Write the operating hours and value of the load population recorder on the housing of the new LIS-SE.
