Up to three pairs of protective photoelectric barriers of type ECO can be connected in
series directly to the TNT 35. The supply of the protective photoelectric barriers comes
directly from the power supply of the installation/machine. Test monitoring of the photoelec-
tric barriers is carried out by the TNT 35.
