“Centurio PRO” standard settings.
Standard settings are: Probes calibration and operating modes (bleed - inhibitor - biocide). To calibrate each channel
select it within main menu. Channels availability is based on modules conguration. The controller will automatically add
the proper channel when a new module is installed and detected.
Conductivity calibration menu.
This menu includes probe choice, conductivity calibration , temperature compensation and manual or automatic temperature
compensation. Conductivity calibration procedure involves a zero calibration (First Point) and a 2nd calibration point (Second
Point) that requires a buffer solution with value near working range. Furthermore Temperature and Automatic Compensation
must be set. Note: This procedure assumes that CONTROLLER is correctly installed and congured, connected
to a working probe. Calibrate using plant’s temperature otherwise unattended results might occur. If something
wrong occurs use RECOVERY CALIBRATION to restore to previous calibration.
First Point & Second Point.
During this procedure probe must be dry and clean and not installed in plant. Tap on “First Point” (zero) and conrm it.
Tap on “Second point”, dip probe’s head into buffer solution and wait until reading value is stable, enter buffer solution
value and conrm it.
Temperature Compensation (if available)
Conductivity measurements are temperature dependent. The degree to which temperature affects conductivity varies
from solution to solution and can be calculated using the following formula: C25 = C / {1+[a/100(t-25)]} where: C25 =
slution conductivity at 25°C, C = conductivity at operating temperature, a = temperature coefcient of solution %/°C.

Samples alphas (a) are listed in the table above. To determine that “a” of other solutions, simply measure conductivity at
a range of temperatures and graphic the change in conductivity versus the change in temperature. “Centurio PRO” has
either xed or adjustable automatic temperature compensation referenced to a standard temperature of 25°C.
Otherwise choose automatic temperature compensation and set % Alpha value.

Chlorine calibration menu.
Chlorine calibration procedure is based on installed chlorine probe and may involve one or two calibration points depen-
ding on probes’ model (see table at next page). From main menu choose “Chlorine” then tap on Calibration”. Installed
probe will be automatically detected and according to model a one or two points calibration will be enabled.
Note: This procedure assumes that CONTROLLER is correctly installed and congured, connected to a working
probe. Calibrate using plant’s temperature otherwise unattended results might occur. If something wrong occurs
use RECOVERY CALIBRATION to restore to previous calibration.
Two points calibration method.
During this procedure probe must be dry and clean and not installed in plant. Use chlorine free water (or a carbon lter
system) and dip probe’s head into it, wait until reading is stable, then ap on “First Point” (zero) to conrm it.
For Second point calibration use a plant’s sample water and analyze it using a DPD system to obtain value. Enter this
value as second point calibration and conrm it.
One point calibration method (second point).
For Second point calibration use a plant’s sample water and analyze it using a DPD system (photometer) to obtain
value. Enter this value as second point calibration and conrm it.

Note: some probes aren’t supported.

12
Tracer calibration menu.
Tracer calibration procedure is based on two buffer solutions (0 BTSA and “working value” BTSA buffer solutions).
According to installed probe, before calibration, congure the model using “Probe Tracer” menu.
Note: This procedure assumes that CONTROLLER is correctly installed and congured, connected to a working
probe. Calibrate using plant’s temperature otherwise unattended results might occur. If something wrong occurs
use RECOVERY CALIBRATION to restore to previous calibration.
Two points calibration method.
During this procedure probe must be dry and clean and not installed in plant. Tap on “First Point” (zero) and conrm it.
Tap on “Second point”, dip probe’s head into buffer solution and wait until reading value is stable, enter buffer solution
value and conrm it. Note: buffer solution value may change if environment temperature it’s different than 20°C.
Read solution’s label for more information. According to this occurrence “Default” must be changed. During
calibration LIGHT could interfere with buffer solution reading value. Execute calibration in a dark environment.
pH calibration menu.
pH calibration procedure is based on two buffer solutions (usually 7pH value for rst point and 4pH value for second point).
Calib 1st Point.
Once into calibration menu move tap on “First Point” then dip probe’s sensor on 7pH buffer solution. Wait until
reading value is stable and according to buffer solution value enter it on calibration field. (“Cal. at” field). Confirm
it or discard if not satisfied. Note: buffer solution value may change if environment temperature it’s different than
20°C. Read solution’s label for more information. According to this occurrence “pH Default” must be changed. If
something wrong occurs use RECOVERY CALIBRATION to restore to previous calibration.
Calib 2nd Point.
Once into calibration menu move tap on “Second Point” then dip probe’s sensor on 4pH buffer solution. Wait until
reading value is stable and according to buffer solution value enter it on calibration field. (“Cal. at” field). Confirm
it or discard if not satisfied. Note: buffer solution value may change if environment temperature it’s different than
20°C. Read solution’s label for more information. According to this occurrence “pH Default” must be changed.If
something wrong occurs use RECOVERY CALIBRATION to restore to previous calibration.
Temperature calibration.
For each channel, where available, there is a temperature probe to be used for proper probe’s compensation. To
calibrate the PT100 sensor a professional thermometer is required to obtain a reliable calibration. Within each channel
calibration menu, tap on “Calib Temperature” to begin setup. Using an external thermometer to read actual temperature
and enter value in calibration eld. Conrm or discard changes. Note: for pH calibration / Temperature compensation see
curve at page 29.

“Set-Point Cl” (PWM) mode - Digital
This mode is valid for any “Digital” output available. Pulse-width modulation (PWM) of a signal or power source
involves the modulation of its duty cycle, to either convey information over a communications channel or control the
amount of power sent to a load. This mode works over a settable (0 to 100 seconds) time to switch on or off selected
output. During this time if reading value will move towards a set value (on or off) the PWM will operate the output on
timered basis. Reaching the set value the PWM will permanently leave on or off the output. Parameters to set for this
mode are:
Unit Value + %: (time activity towards set value. 0% means 0 seconds. 100% means 100 seconds.)
Cl range: two Cl values within PWM operates.
For example: set rst Cl value at 1.40 = 00% and second Cl value at 0.80 = 60%.
For reading values ≥ to 1.40 the output will be permanently OFF.
For reading values ≤ 0.80 the output will be ON for 60 seconds and OFF for 40 seconds.
If reading value is 1.1 mg/l then the output will be active at 30% (ON for 30 seconds, OFF for 70 seconds).
“Set-Point Cl” (on/off) mode - Digital
This mode is valid for any “Digital” output available. On/Off mode set the CONTROLLER to operate using two set
values that enable or disable the Cl pump. To use this mode tap on On/Off working mode. Tap on it.
ON/OFF mode
Set Cl value at 0.80 mg/l ON and 1.00 mg/l OFF. The difference between the two Cl values is called HYSTERESIS.
CONTROLLER will enable the Chlorine pump when reading value will decrease at 0.80mg/l
At 0.80mg/l the Chlorine pump will be enabled until reading value will increase at 1.00mg/l.
Pulse speed: to let pump operate at pulses per minutes add one or more minute (1pulse every xx minutes).

Did you know ?
In chemistry, an alkali is a basic, ionic salt of an alkali metal or alkaline earth metal element. Alkalis are best known for
being bases (compounds with pH greater than 7) that dissolve in water. The adjective alkaline is commonly used in English
as a synonym for base, especially for soluble bases. This broad use of the term is likely to have come about because
alkalis were the rst bases known to obey the Arrhenius denition of a base and are still among the more common bases.
Since Brønsted-Lowry acid-base theory, the term alkali in chemistry is normally restricted to those salts containing alkali
and alkaline earth metal elements.
An acid (often represented by the generic formula HA [H+A−]) is traditionally considered any chemical compound that,
when dissolved in water, gives a solution with a hydrogen ion activity greater than in pure water, i.e. a pH less than 7.0.
That approximates the modern denition of Johannes Nicolaus Brønsted and Martin Lowry, who independently dened
an acid as a compound which donates a hydrogen ion (H+) to another compound (called a base). Common examples
include acetic acid (in vinegar) and sulfuric acid (used in car batteries). Acid/base systems are different from Cl reactions
in that there is no change in oxidation state.

“Set-Point pH” (PWM)
This mode is valid for any “Digital” output available. Pulse-width modulation (PWM) of a signal or power source invol-
ves the modulation of its duty cycle, to either convey information over a communications channel or control the amount
of power sent to a load.
This mode works over a settable (0 to 100 seconds) time to switch on or off selected output.
During this time if reading value will move towards a set value (on or off) the PWM will operate the output on timered
basis. Reaching the set value the PWM will permanently leave on or off the output.
Parameters to set for this mode are:
Unit Value + %: (time activity towards set value. 0% means 0 seconds. 100% means 100 seconds.)
pH range: two pH values within PWM operates.
For example: set rst pH value at 8.00 = 100% and second pH value at 4.0 = 0%.
For reading values ≥ to 8.00 the output will be permanently ON.
For reading values ≤ 4.0 the output will be permanently OFF.
For reading value of 7.00 the output will be OFF for 25 seconds, ON for 75 seconds.
For reading value of 6.00 the output will be OFF for 50 seconds, ON for 50 seconds.

enable or disable the pH pump. To use this mode tap on “Proportional First Point”. Tap on it.
PROPORTIONAL mode between 7pH(0 P/m) and 8pH (180 P/m). p/m is : pulses per minute
In this mode the pH pump will be “ON” for values greater than 8pH with maximum set pulses per minute capacity (e.g.:
180) and it’ll be “OFF” for values lower than 7pH. For values of 7.5pH pump will be “ON” with 90 pulses per minute
capacity.
