P2: This parameter allows to configure the working mode of level contact: 0 = NO (normally open,

standard configuration) 1 = NC (normally closed, fail-safe mode).
P3: This parameter allows to store the status of the ON/OFF button at the system shutdown: 0 = at
start-up the pump is always enabled 1 = at start-up the pump restores its status at shutdown.
P4: This parameter allows to set the pump working mode:
0 = OFF the pump is always off, independently from measured value: this option allowsto
monitor the measurement without intervening, for example during the plant start-up
1 = ON thethe pump is always on, independently from measured value: this option is used
to manually force the dosage, for example during the plant start-up or maintenance
2 = ON/OFF acid thethis option is typically used for acidification; the pump activates when
the measurement exceeds the "working threshold + ½ hysteresis" level, and deactivates when
the measurement falls below the "working threshold – ½ hysteresis" value
3 = Proportional acid the pump is definitely active when the measurement is greater than
the "working threshold + ½ hysteresis" level, and definitely off when measurement is lower
than the "working threshold – ½ hysteresis" value, while for measurements between these
limits, the operating time of the pump is proportional to the distance of measurement from
the limits. The time base is fixed (90 seconds) and operation follows the trend shown in the
table below:
Measurement = pH ; Working threshold = 7.20 pH ; Hysteresis = 0.40 pH

4 = ON/OFF chlorinethis option is typically used for chloration or alkalinization; the pump
activates when the measurement is lower than the "working threshold – ½ hysteresis"
value, and deactivates when the measurement exceeds the "working threshold + ½
hysteresis" level
5 = Proportional chlorinethe pump is definitely active when the measurement is lower
than the "working threshold – ½ hysteresis" value, and definitely off when measurement is
greater than the "working threshold + ½ hysteresis" level, while for measurements between
these limits, the operating time of the pump is proportional to the distance of measurement
from the limits. The time base is fixed (90 seconds) and operation follows the trend shown
in the table below:
Measurement = Redox ; Working threshold = 680 mV ; Hysteresis = 20 mV
