9.4.1.3 Probes Parameters
This menu allows the operator to enable the analysis probe for gas and
chemicals level taks. Furthermore it is possible to set the parameters of
the probes.
n
Residual Chlorine Dioxide
n

sensor
(not for compact models)
After the connection between the sensor (or the output of an analysis ins-
trument with “extern” sensor) and the AI2 input (input 4 – 20 mA, termi-
nals 77 – 78 on the junction box) the operator shall set the parameters as
follow.
n
Sensor
: Absent
→
Through this parameter it is possibile to confirm
the presence of the sensor.
n
AI Sensor Input
: --
→
Set the analogic input number linked to the the
sensor. Actually the only available input is the 02.
n
F.Scale. an. probe (mg/l)
: 0.5
→
Setting this parameter the operator
can insert the sensor full – scale value and then the corrispondent va-
lue at 20 mA.
n
Minimum level (mg/l)
: 0.00
→
Trough this parameter it is possibile
to set a threshold in order to signal a minimum level. It is possible to
couple it with a relay output for remote control.
n
Maximum level (mg/l)
: 0.50
→
Trough this parameter it is possibile
to set a threshold in order to signal a maximum level. It is possible to
couple it with a relay output for remote control.
n
Max production off
: NO
→
Switching on “YES” the operator will ob-
tain the production stop after passing the maximum threshold seen in
the previous paragraph. The production will start again after the misu-
ared value will be lower than the threshold minus the hysteresis.
n
Hysteresis (mg/l)
: 0.01
→
This is set on the hysteresis value concer-
ning the maximum and the minimum level.
n
Alarm delay (s)
: 060
→
Set the alarm delay compared to the warning
for passing both threshold.
For the first calibration and following corrections see chapter 9.3.3 „Cali-
bration of the dioxide sensor“ on page 24.
If the the probe is a passive one, in other words it needs external power
supply, the operator shall switch the jumper cable as in the follwing pic-
tures.

Chlorite Sensor
(not for compact models)
After the connection between the sensor (or the output of an analysis ins-
truments with “extern” sensor) and the AI4 input (input 4 – 20 mA, termi-
nals 79 – 80 on the junction box) the operator shall set the parameters as
follow.
n
Sensor
: Absent
→
Through this parameter it is possibile t confirm the
presence of the sensor.
n
AI Sensor input
: --
→
Set the analogic input number linked to the the
sensor. Actually the only available input is the 04.
n
F.Scale. an probe (mg/l)
: 2.0
→
Setting this parameter the operator
can insert the sensor full – scale value and then the corrispondent va-
lue at 20 mA.
n
Maximum level (mg/l)
: 0.80
→
Trough this parameter it is possibile
to set a threshold in order to signal a maximum level. It is possible to
couple it with a relay output for remote control.
n
Hysteresis (mg/l)
: 0.01
→
This is set on the hysteris value concer-
ning the maximum and the minimum level.
n
Alarm delay (s)
: 060
→
Set the alarm delay compared to the warning
for passing both threshold.
