OPERATING MODES GLOSSARY
ON-OFF mode
•Unit is provided with ON-OFF mode which will activate (or deactivate in case of reverse mode ON) output relays Constant / ON-OFF
dosing pumps mode or other ON-OFF equipment.
BENEFITS: it will work with most of ON-OFF equipment, which are also cost effective.
DISAVANTAGES: due to dosing equipment high output performance rate (frequency for dosing pump and peristaltic dispensers with motor
rpm), this will result to a slight different values between actual measurement in the system and what controller shows.
USING EXTRA ON-OFF RELAY OUTPUT
•ON-OFF Relay probably will connect a dosing pump; the free available relays can connect an alarm device (buzzer and light),
programming different values then the ones for dosing pumps.
BENEFITS: increase safety measurements ensuring warning in case parameters are out of control.
DIRECT / REVERSE DIRECTION MODE
•Set points relays Direction mode are set as default as follow:
Set point 1 EC (conductivity measure: DIRECT mode, meaning that output is active when measured value is lower than selected set-
point. Set point 2 is set with REVERSE direction mode output is active when measured value is higher than selected set-point..
ALARM HIGH / LOW FUNCTION
•Alarm function allows selecting two points high and low passed which controller will go into alarm. Set point 2 relay can function as Alarm
connecting and diving an alarm device or other equipment (only Alarm High or Low).
BENEFITS: increase safety measurements ensuring warning in case parameters are out of control.
HYSTERESIS
•Hysteresis is useful during ON-OFF mode set-point adjustment operations and is used to activate or deactivate output relays when
selected hysteresis is reached. Hysteresis is useful when there are too many and/or quick changes around set point, which could damage
connected equipment. Increasing Hysteresis will allow moving away from set point according to required value.
Example with range 2000 μS: if selected set-point is 700 μS EC and Hysteresis set to 100 μS, the two active points are 600 μS and
800 μS: within this range, set-point is OFF and outputs are blocked, outside this range set-point is ON (always in accordance with direct
or reverse mode).
BENEFITS: ensuring good control the systems without stressing connected equipment.
DISAVANTAGES: user must remember that programmed hysteresis is slightly different from required set point.

16
ENGLISH
DELAY
•Delay time blocks relay outputs (max 999 sec. programmable) to ensure that the outputs are active only when the sensors
measurements are stable thus allowing the best results in terms of chemical balance.
TIMED PULSES MODE (PWM) PULSES WITH MODULATION TIME/PAUSE
•Timed Pulsesalso known as PWM “pulses with modulation” time/pause allows proportional mode on each ON-OFF set-point activating
corresponding pulses with Start/Stop time cycle variation according to measured value in respect to set-point.
Window Width (example range 2000 μS): pulses are timed ON and OFF according to the distance from selected set-point,
programmable, example: if selected set point is 700 μS EC and measured value is 600 μS, PWM mode will start after reaching 650 μS
with Time/Pause pulses and decreasing the active time while reaching set point value.
Cycle Time: PWM mode cycle 60 seconds (programmable): example set point 700 μS = active time 60 sec - pause time = 0 sec.; 675
ppm active time= 30 sec / pause time 30 sec.....and decreasing active time accordingly while reaching set point value. Cycle time
depends on many variables such as: distance from injection point to treating system, how fast or slow set point must react, chemical
concentration, etc....
Active Time MIN programmable: it sets the minimum time in which PWM is active; it overrules selected settings. Times Pulses function is
adjusted via 3 functions following the formula:
Active Time according to selected formula = (measured value – set point) / window width * cycle time If the result of the formula is < the
selected Active Time Min, the latter with overrule the first, example range 2000 μS: measured 600 μS -set point 700 μS / Window Width
0.50 *Cycle time 60 sec=active time 4 sec.
In case user has selected Active time min 5 sec., this will be minimum time of PWM and not 4 sec.
BENEFITS: a simile-proportional function more accurate then ON-OFF mode using simple equipment such as Constant dosing pumps and
peristaltic dispensers.
DISAVANTAGES: not as accurate as mA mode, user needs an accurate selection of dosing unit flow rate.
PROPORTIONAL ANALOG CURRENT OUTPUT 4÷20 mA
•4÷20mA1 and mA2 programmable proportional mode: at 4 mA corresponds selected set-point, at 20 mA corresponds the max
measured distance from selected set point. The active time on the mA outputs is calculated according to the following relation: 0 sec:4
mA / 1 sec:20mA. Analog mA outputs connections are galvanic separated. Controller allows choosing between AUX (driving data logger
or data recorder or other equipment) and Dosing set point (driving dosing pumps) or all equipment suitable to work with mA signal).
BENEFITS: best results because pulses are extremely accurate in relation to measured levels.
DISAVANTAGES: user needs a specific dosing pump for such operational mode.
OVERDOSING TIME
•Over dosing time-out alarm allows to select a period of time in which set point must be reached. If during this time set point is not
reached, controller will block outputs operations including mA outputs (dosing pump), Alarm is ON shown on display and will activate a
signalling device connected to alarm relay.
BENEFITS: to prevent excess of chemical addition.
START-UP DELAY
•Start-up Delay time “freezes” the relay outputs when switching ON the unit thus allowing sensors to polarize ensuring correct
measurements (programmable).
FLOW SENSOR “PROXIMITY SWITCH” FUNCTION
•Flow Sensor: in case, no water is running through the sensor cell holder (and eventually into the systems), flow sensor (proximity switch)
will deactivate all outputs ensuring that no extra chemical is added.
TEMPERATURE
•Manual temperature compensation. 0÷100°C. Selecting TEMP.PROBE (latter temperature sensor) compensates temperature/electrode
measurements, always giving the exact value against the current temperature.

INITIAL DISPLAY
NOTES FOR PROGRAMMER: try not to press the keys continuously. First, read the manual before programming or have the
booklet handy so to be sure to perform a correct selection.
IMPORTANT: if keys are not pressed during 60 seconds, controller will display current measurements.
For rapid advancement, keep pressed firmly either one of ◄► keys
When the controller is turned ON there will be displayed at the bottom the latest software upgrade.
Software is subject to revision without further notice.
Controller will get set for measurements and ready to work.
at this point there could be some here are displayed some other messages status such as:
S1 S2 L1 ALARM OVERDOSING FLOW *BASIC MENU* *EXPERT MENU*
which could be ON due to actual measurements, just go ahead with programming.
Display shows pH, Redox mV and Chlorine ppm measurements. If controller has been already programmed, display shows
previously selected set points.
INITIAL DISPLAY
shows measurements according to the K range selected in the next
paragraph.
If the controller has been already programmed, display will show previously
selected programs.
CONTINUOS MEASUREMENT DISPLAY
shows when parameter measurements, function
status and alarm indications.
When the controller is turned ON for the first time, th
ere will be displayed a list of all the
programming function keys which will not appear in the next switching ON operations.
CAREFULLY READ KEY USAGE THEN PRESS
OK to start

Selecting Conductivity (EC) “K” factor
Conductivity EC value automatically adjust itself for various conductivity ranges by adapting the controller to the probes cell costant
“K” characteristic.
Controller covers ranges from cell costant K 1 up to 20.00 mS and even 100.00 mS (latter with graphite sensor electrodes) and
costant K 5 ranges 2.000 μS. Display will show µS values but in case setpoint value exceed 1999 µS, it will show 2.00 mS (decreasing the
value will return to µS reading). Selecting K5 (5.000) range setpoint value 100 µS.
IMPORTANT: the above μS ranges are just indicative: for example a K1 probe can make good measurements below 1000 μS, only
resolution will be less accurate. However the same concept doesn’t apply the other way for high ranges.

Set point will activate output relays for dosing pumps or other
equipment once selected set-point level is reached. Display will
show µS values but in case setpoint value exceed 1999 µS, it
will show 2.00 mS (decreasing the value will return to µS
reading). Selecting K5 (5.000) range setpoint value 100 µS
Direct mode operation: output is active when measured value is
lower than selected set point thus driving connected equipment.
Reverse mode works the opposite way.
Unit is provided with ON-OFF mode which will activate (or deactivate in case of reverse mode ON)
output relays such as Constant / ON-OFF mode dosing pumps or other On-Off equipment.
