5. Selection of the programmable output functions
Of the 5 available output functions, maximally 3 can be programmed to the
outputs OUT1, OUT2 and OUT3 of the analyser. The output function "Perma-
nent signal" exists twice (PR1 and PR2). With the output function PR2, the relay
can be activated in the event of a fault as well as when the preset water hard-
ness is exceeded. In programme step 5.4 it is determined whether the outputs
are active when the electrical voltage is switched off or live.
Parameters – such as the pulse length – must also be entered for the selected
output functions in programme steps 6.1 to 6.11. A description of the outputs
can be found in the chapter Output functions on page 8.

Select the activation of the output functions for the outputs selected in pro-
gramme steps 5.1 to 5.3.
"-" Activation of the selected output function with relay inoperative (dropped-
out)
"|" Activation of the selected output function with relay operative (pulled-in).
General note:
In deciding whether e.g. a valve is active when live i.e. open or not, one considers the reaction of
the treatment plant in a current-free state. In such a case no undesired functions should occur in the
plant.
Example flush valve: When the analyser is switched off, a rinse valve must not be open, even if it is
triggered by an external supply voltage.
Choose a flush valve that opens when carrying voltage and programme "|".
Example fault message: When the analyser has no electrical power, a fault message should occur. Programme "-".
