Analysis run mode
(not for compact models)
In the
Analysis Run Mode
the production control is proportional to the
gap between a desired set value compared to the analysis value measu-
red. The analysis can be performed using a probe directly connected to
the control device or using an external tool with a analogic signal
(0/4 – 20 mA) as outputs to the control unit.
The applied regulation is PID type.
The operator shall set the parameters covering the type of operation, in
detail:
i
All PID parameters shall be Entered with the utmost care by
duly qualified personnel only.
n
Analysis Probe
: external
→
This parameter sets if the test sensor is
internal, therefore directly connected to the electronic control unit, or
external, therefore connected to a device connected to the electronic
control unit through an analog signal retransmitting the sensor mea-
sure.
n
F. scale an. probe (mg/l)
: 001
→
If an external sensor is foreseen,
this parameter allows to Enter the full scale value of the sensor or of
the value corresponding to 20 mA of the incoming external signal.
n
Proportional band (%)
: 010
→
This parameter sets the setting ran-
ge, that is the value (compared to the full scale value of the sensor
used) within which the PID setting is performed.
n
Integral time (min)
: 0000
→
This parameter sets a time value inside
the PID setting integrating the delay time (time elapsing between the
dosing operation and the relevant sensor reading change) included in
any dynamic system.
n
Derivative time (min)
: 0000
→
This parameter sets a time value in-
side the PID setting creating an anticipation of further events (for ex. a
tub between the dosing operation and the test).
n
Max. production rate (%)
: 100
→
This parameter allows to reduce
the max. production capacity of the machine so to limit its potential
while operating in automatic mode.
n
Sample flow check
: no
→
This parameter enables to control the
sample flow touching the reading sensor. This can only occur when a
flow sensor is mounted on the probe holder.

Batch
The batch mode allows to produce a “diluted” ClO
2
solution. The produc-
tion occurs stocking this solution in a tank whose minimum and maxi-
mum levels control respectively the start and stop of the production. The
concentration range is programmable from 0,5 to 2,5 g/l.
In order to set this function mode the first step is to set the inputs (storage
level) and the output (solenoid on the prediluition line) mandatory to the
correct system functioning.
For more informations look at chapters „Configuration inputs 8, 9, 10, 11,
12“ on page 27 and „Configuration outputs 10, 11, 12“ on page 27
described in the next pages.
The operator shall set the parameters covering the type of operation, in
detail:
Flow rate input AI6
: setting range 4 – 20 mA or pulse
→
It represents
the type of signal coming from the flow meter of the pre-dilution water
that controls the production.
Flow rate F.S. (m3/h)
: 01.00
→
It represents the maximum flow rate va-
lue corresponding to 20 mA, or the maximum value presumed when a
pulse input is foreseen.
Pulse constant (l/p)
: 001.0
→
It represents the pulse emission constant
when a pulse-emitting water counter input is foreseen.
Solution max. conc. (g/l)
: 1.50
→
This parameter sets the concentrati-
on value of the solution produced and stored. Setting range 0.5 – 2.5 g/l.
Solenoid valve closing delay (s)
: 1.50
→
This parameter sets the delay
time to close the disconnecting valve of the pre-dilution line/tank filling.
Setting range 00 – 60 s.
