TEXT DISPLAY LCA 042
8
1) Due to standardization of the input signals the designations have
been altered. The old designations are given in brackets. You may
still find these designations on some LCA units.

THE MESSAGE VARIANTS
Optionally the function inputs can be:
- hard-wired (open input corresponds to “log 0”)
- driven by keys and switches
- driven by programmable controller outputs

THE MESSAGE VARIANTS
You determine the message variant or operating mode of
text display LCA 042 using the 3 function inputs
- DIRECT/SEQUENTIAL
- TEXT/VARIABLE (TEXT/DATA)
1)
- CLOCK (DATA-CLOCK)
1)
DIRECT MESSAGE
A message is invoked and displayed for as long as the
coded message number is present on the LCA 042.
MULTI-LINE MESSAGE
If one line per message is not enough, then to each main
message two additional messages, two additional lines,
can be invoked with CLOCK.
FIRST MESSAGE
The LCA 042 displays the first message first, all other
messages (max. 19) are registered in the order of their
appearance in the message memory. The last two
columns of the messa-ge line give information on the
number of messages registe-red. These messages are
invoked one after the other with CLOCK.
CYCLIC MESSAGE
All messages (max. 19) are registered in the message me-
mory and displayed in rotation. The last two columns of
the message line give information on the number of
messages registered. The CLOCK must be at log 1 (+24V).
EXTERNAL VARIABLES
The LCA 042 can combine fixed texts with external varia-
bles. The number of variables and their position on the
message line can be determined using place holders.
