Operation - Leuze electronic DDLS 200 Technical Description

Operation

In running operation ("Automatic" operating mode) the DDLS 200 operates maintenance-free. Only
the glass optics need to be cleaned occasionally in the event of soiling. This can be checked by ana-
lyzing the switching output OUT WARN (with the INTERBUS fiber-optic-cable model, a peripheral er-
ror message is also available). If the output is set, soiling of the DDLS 200's glass optics is often the
cause (see chapter 12.1 "Cleaning").
It must still be ensured that the light beam is not interrupted at any time.
Attention!
If, during operation of the DDLS 200, the light beam is interrupted or one of the two devices
is switched voltage free, the effect of the interruption on the entire network is equivalent to
the interruption of a data line!
In the event of an interruption (light beam interruption or switched voltage-free), the
DDLS 200 switches off the network to a non-interacting state. The system reactions in the
event of an interruption are to be defined together with the supplier of the PLC.
