LED indicators INTERBUS 2Mbit/s fiber-optic cable

In addition to the indicator and operating elements present in all device models (bar graph, buttons,
LEDs AUT, MAN, ADJ; see chapter 11.1 "Indicator and operating elements"), the INTERBUS model
includes the following additional indicators:
UL RC BA
RD FO1 FO2
UL = logic voltage U
RC = Remote Bus Check
BA = Bus Activity
RD = Remote Bus Disable
FO1 = Fiber Optics 1
FO2 = Fiber Optics 2

Note!
The DDLS 200 is an INTERBUS subscriber (Ident-Code: 0x0C = 12
scriber description can be downloaded from http://www.leuze.com.
If the value falls below the warning level (bar graph), a peripheral error message is transmit-
ted via the INTERBUS. When this error message is transmitted, the usual cause is soiling
of the glass optics (see chapter 12.1 "Cleaning"), an incorrectly adjusted data transmission
path, or an interrupted light path.
You can also use the diagnostic options available via the INTERBUS.
