With single-channel wiring the safety level of your machine/plant may be
lower than the safety level of the unit (see Safety characteristic
data [ 22]).
NOTICE
When operated with a light grid or sensor
– It must not be possible to switch off the supply voltage for the PNOZ-
sigma separately from the supply voltage for the light grid or safety
switch.
– The operating mode selector switch must be set to "Without detection
of shorts across contacts", as shorts across contacts are detected by
the ESPE.
