DANGER!
If for one of the output channels you set Detection = OFF, the warning appears
that the output channel does not satisfy SILCL 3 (IEC 62061) and PL e
(ISO 13849-1) 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 SILCL 1 (or maximum SILCL 2 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.
