3 SUPERVISORY AND SAFETY FUNCTIONS
A warning is given when a safety risk is sensed beforehand, and the hoisting motion is
immobilized in the event of a safety risk. Note that the CU1 is connected in the lifting
circuit only and thus lowering of the load is always possible.
All basic parameters are factory-set and they are based on the FEM standards
(Federation Europeenne de la Manutention). See chapter 5.
Note 1:
When the built-in maximum value of SWP, Run Time, Starts or Overloads is
reached, it is still possible to use lifting and lowering motions, but the use of
the hoist has exceeded a safety limit according to the selected hoist class.
In this case, the hoist should be totally checked and renewed according to
the instructions by KCI Konecranes.
3.1 Calculating of the hoist's Safe Working Period (SWP)
CU1 calculates and displays the remaining hoist's safe working period (SWP) in hours.
The calculation basis on the design rules of the FEM-standards (see chapter Safe
Working Period in Service Manual or in Owners Manual). According the FEM-standards
the calculation has to be based on the load spectra and the corresponding operating
hours. The CU1 calculates the SWP continuously and the calculation is based
accurately on the measured load (Q) and the running time (t) during each work cycle:
The displayed value is the remaining safe working period with the rated (100 %) load of
the hoist in the selected hoist class and according the very heavy load spectra. SWP
indicates how many hours the hoist can still be used with the rated load according to
the selected hoist class.
