Operation

During 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 analyzing
the switching output OUT WARN (with the INTERBUS fiber-optic-cable model, a peripheral error mes-
sage 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 control system.
