Special functions for the digital outputs

(This menu is only accessible if 'Fixed' is selected
as described in section 7.3.)
It is possible to perform AND logic sequences by
means of the digital in- and outputs.
For example the Comtroller 702 can be program-
med to activate a digital output when 2 digital
inputs are ON. The digital signals can also derive
from exeeding a limit value on an analog input - or
a combination of a signal caused by exceeding a
limit value and an active digital input.
The following signals can be combined:
-

digital input 1 - 4

analog limit HIGH 1 - 2

analog limit LOW 1 - 2

combi alarm 1 - 8
