Fig. 82: Examples of iParameter settings for DX581-S Safety module; input channels are paired as “Channel
X with Channel X + 4”
DANGER!
If for one of the output channels you set Detection = OFF, the warning appears that the output channel
does not satisfy SIL3 (IEC 62061) and PL e (EN ISO 13849) requirements in such condition. Two
safety output channels may have to be used to satisfy required SIL or PL level.
The parameter “Detection” was created for customers who want to use safety outputs of DX581-S for
SIL1 (or maximum SIL2 under special conditions) or PL c (or maximum PL d under special conditions)
safety functions and have less internal DX581-S pulses visible on the safety output line. Such internal
pulses could be detected as LOW signal by, for example, drive inputs, which would lead to unintended
machine stop.
