Limit supervision
For the supervision of limits of measured values 5
threshold outputs can be programmed. Each
threshold output can be assigned to up to three
comparators (A, B, C). For each comparator,
2 limits and two measured values or
2 limits and 1 measured value or
1 limit and the minimum connection time can
be programmed. The function of the corresponding
combination can be seen in the following diagrams.

Diagr. Principle diagram limit supervision
If a limit violation is detected in one of the compara-
tors
"A", "B" or "C", the threshold output is activated.
The violation is registered within the event memory
with date and time and can be given out via a „Digi-
tal Output“.
The assignment of a threshold output to a „
Digital
Output
“ is carried out while programming the digital
outputs.
Limits may be positive or negative. Negative limits
are marked with a "-" before the limit.
