Summary of the Reliability Study
Synthesis of Reliability Study in Configuration 1 Remote Device & 1 Base Station
(1) IEC 62061 standard concerns integration. This standard distinguishes the overall safety
function (classified SIL1, SIL2, or SIL3 according to diagrams in §1.4) from components which
constitute the safety function (classified SIL1 CL, SIL2 CL or SIL3 for eXLhoist).
NOTE: The table above is not sufficient to evaluate the PL of the hoisting system. The PL
evaluation has to be done at the system level. The fitter of the integrator of the eXLhoist has to do
the PL evaluation by including sensors and actuators data numbers from the table above.
SISTEMA software can evaluate the PL of the system.
NOTE: The radio communication of the Wireless Remote Control System is compliant with IEC
61784-3 Ed2 2010.
