- mV - NTU - Temperature. Customized version includes: potentiostat (mg/l Cl2) and Fluorine (F)
Once into “measure submenu”*, is possible to edit (all or some) the following setpoint parameters:
[Da] “setpoint output A” that can be congured as on/off, PWM or PID and settable as 1 to 6 channel
[Db] “setpoint output B” that can be congured as on/off, PWM or PID and settable as 1 to 6 channel
[Pa] “proportional pump output A” and settable as 1 to 6 channel
[Pb] “proportional pump output B” and settable as 1 to 6 channel
[mA] “mA output” settable as 1 to 6 channel
[Aa] “general alarm A” for “out of limits” reading parameters
[Ab] “general alarm B” for “out of limits” reading parameters
[Ad] “general alarm” for maximum dosing time
[Ar] “general alarm” for damaged probe (same reading after a set time)
Total amount of output-channels available is 6. This number decreases every time a channel is assigned to a specic
function during setup. Once there are no more channels available the instrument will read only probe’s value. For
temperature channel is available ON/OFF mode only during setpoint setup.
Da and Db.
Using Da and / or Db is possible to control the status of “setpoint outputs” and “level outputs” based on some rules.
Refer to “power connections” and “I/O connections” blocks at page 4 and 5 to locate these outputs on mainboard.

Da and Db WORKING MODES.
ON/OFF Mode.
On/Off mode set the instrument to operate using two set values that enable or disable the related setpoint output.
Parameters to set for this mode are:
ON: Activate RL and LEV on moving towards the unit value (for example: pH)
OFF: Disable RL and LEV on moving towards the unit value (for example: pH)
IN: assign “input” number then edit the name by moving wheel. If the “input” number is already used then it will not be
shown. Choose “X” instead of a number to disable input.
RL: assign “relay” number then edit the name by moving wheel. If the “relay” number is already used then it will not be
shown. Choose “X” instead of a number to disable relay.
STOP: (“ON”: when product into tank is ending, then the related output will be off and an alarm condition will pop-up.
“OFF”: when product into tank is ending, then the related output will continue to stay on and an alarm condition will pop-up.)
MSG: when agged an SMS or EMAIL alarm message will be sent to destination edited in GSM menu.
ON/OFF mode while dosing ALKALI

PWM Mode.
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.
Time resolution is 5 seconds, 5 steps. 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.)
IN: assign “input” number then edit the name by moving wheel. If the “input” number is already used then it will not be
shown. Choose “X” instead of a number to disable input.
RL: assign “relay” number then edit the name by moving wheel. If the “relay” number is already used then it will not be
shown. Choose “X” instead of a number to disable relay.
STOP: (“ON”: when product into tank is ending, then the related output will be off and an alarm condition will pop-up.
“OFF”: when product into tank is ending, then the related output will continue to stay on and an alarm condition will pop-up.)
MSG: when agged an SMS or EMAIL alarm message will be sent to destination edited in GSM menu.
For example: set rst pH value at 10.00 = 100% and second pH value at 5.0 = 0%.
For reading values ≥ to 10.00 the output will be permanently ON.
For reading values ≤ 5.0 the output will be permanently OFF.
For reading value of 9.50 the output will be OFF for 10 seconds, ON for 90 seconds.
If reading value decreases to 8.00 then the output will be OFF for 20 seconds, ON for 80 seconds.
Notes: for values within 1% and 5% MAX5 will assume 5% as usable value.
for values within 95% and 99% MAX5 will assume 95% as usable value.

PID Mode.
A proportional–integral–derivative controller (PID controller) is a generic control loop feedback mechanism.
PID controller attempts to correct the error between a measured process variable and a desired setpoint by calculating
and then outputting a corrective action that can adjust the process accordingly.
The PID controller calculation (algorithm) involves three separate parameters; the Proportional, the Integral and
Derivative values. The Proportional value determines the reaction to the current error, the Integral determines the
reaction based on the sum of recent errors and the Derivative determines the reaction to the rate at which the error has
been changing. The weighted sum of these three actions is used to adjust the process. By “tuning” the three constants
in the PID controller algorithm the PID can provide control action designed for specic process requirements. The
response of the controller can be described in terms of the responsiveness of the controller to an error, the degree to
which the controller overshoots the setpoint and the degree of system oscillation. Note that the use of the PID algorithm
for control does not guarantee optimal control of the system or system stability.
(K
p
) is the constant proportional gain
(K
i
) is the constant integral gain
(K
d
) is the constant derivative gain
(e): error
(t): Time in the past contributing to the integral response
Parameters to set for this mode are:
IN: assign “input” number then edit the name by moving wheel. If the “input” number is already used then it will not be
shown. Choose “X” instead of a number to disable input.
RL: assign “relay” number then edit the name by moving wheel. If the “relay” number is already used then it will not be
shown. Choose “X” instead of a number to disable relay.
STOP: (“ON”: when product into tank is ending, then the related output will be off and an alarm condition will pop-up.
“OFF”: when product into tank is ending, then the related output will continue to stay on and an alarm condition will pop-up.)
ON: Activate RL and LEV on moving proportionally towards the unit value (for example: pH)
OFF: Disable RL and LEV on moving proportionally towards the unit value (for example: pH)
I: integral time (from 0s to 59m:59s)
D: derivative time (from 0s to 59m:59s)

From setup menu (g.3) rotate wheel to highlight “Calibration” then press wheel. Again rotate wheel until to reach desired
calibration measure pH - Cl2 - mV - NTU and Temperature.
pH Calibration.
pH calibration procedure involves two calibration points and it requires two buffer solutions. Default buffer solutions are
pH 4.00 and pH 7.00. pH reading value can be also automatically temperature compensated.
In the following example instrument will calibrate pH using default buffer solutions value.
This procedure assumes that instrument is correctly congured and a working pH probe connected.
Otherwise unattended results may occurr.
Calib 1st Point.
Once into “Calibration pH” menu move wheel on “Calib 1st Pt” then press wheel to enter into rst point calibration
submenu. Prepare 7.00pH buffer solution and dip probe’s sensor on it. Wait until reading value is stable and according
to buffer solution value move wheel until it is the same on display (“pH default” eld). Default value is 7.00pH. To end
procedure move cursor on “OK” and press wheel to proceed to next step.
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.
Calib 2nd Point.
Move wheel on “Calib 2nd Pt” then press wheel to enter into second point calibration submenu. Prepare 4.00pH buffer
solution and dip probe’s sensor on it. Wait until reading value is stable and according to buffer solution value move
wheel until it is the same on display (“pH default” eld). Default value is 4.00pH. To end procedure move cursor on “OK”
