Output functions
Of the 5 available output functions, maximally 3 can be programmed for the outputs of the analyser.
The output function "Permanent signal" is available in 2 different versions. With the output function
"Permanent signal 2" the relay can also be activated in the case of a disturbance in function.
The activation of the outputs Pulse signal and Permanent signal can occur with hard water or soft wa-
ter according to the programming in programme step 1.5.
In programme step 5.4, it is determined whether the outputs are active when the electrical voltage is
switched off or when live.
Pulse signal
The signal serves to trigger signal devices,
programme mechanisms or PLC controls.
The pulse duration can be selected in pro-
gramme step 6.1 between 1 and 999 sec-
onds.
Im programme step 6.2, the number of bad
messages is programmed after which the sig-
nal is activated.
Permanent signal 1
The signal serves to trigger valves, horns or
signal devices that require a permanent con-
tact after the limit value over/underrun.
In programme step 6.3, it is programmed
whether the relay is deactivated again, if on
the next analysis the result "Water good" oc-
curs, or if no further analyses are to be made.
In this case, a deletion must take place by
hand or via the input "Reset relay".
In programme step 6.4, the number of bad
messages is programmed after which the sig-
nal is activated.
Permanent signal 2
The signal serves to trigger valves, horns or
signal devices that require a permanent con-
tact during the limit value over/underrun.
The function corresponds to the output func-
tion "Permanent signal 1". However, the output
relay can also be activated in the event of dis-
turbances in instrument functioning (pro-
gramming 6.7).
A connected shut-off valve is then closed not
only with an over/underrun of the water hard-
ness, but also in the event of a functional dis-
turbance.
In programme step 6.5, it is programmed
whether the relay is deactivated again, if on
the next analysis the result "Water good" oc-
curs, or if no further analyses are to be made.
In this case, a deletion must take place by
hand or via the input "Reset relay".
In programme step 6.6, the number of bad
messages is programmed after which the sig-
nal is activated.
Analysis active
This output function is activated during an
analysis, during the extra flushing and on cali-
bration.
Valves or pumps can be triggered to supply
the analyser with water.
A valve for the cool-water inflow of a cooler
can also be controlled. In order to cool down
the test water initially, the opening of the input
valve in the analyser can be delayed within the
range of 0-999 seconds (programme step
6.8).
Indicator or signal devices can also be con-
nected to display the analysis process.
Signal relay
In programme step 6.9, it is determined with
which fault messages this relay is activated.
