Deselecting SBH
Safe operating stop can be deselected using SGE "SBH/SG deselection" (= "1"
signal); this results in a general deactivation of SBH and SG. The SBH function is
also deselected when the SG function is selected using the SGE "SBH deselec-
tion".
Warning
!
The delay time must be selected as a function of the distance to the hazardous
location. The speeds to be taken into account in this respect are stipulated in
Standard DIN EN 999.
