EF110_r1.0 – 10/2019 p. 18
CONFIGURATION
To configurate the pump accordingly with your application needs, refer to the below instructions.
Meaning of parameters
P1: This parameter allows to select the measurement type, pH or redox (mV).
When setting P1=0 (pH reading with two decimal), please note that the two decimal places
are visible only for pH values below 10, because the display can show up to three digits.
However, generally the precision of pH measurements with one decimal is sufficient in most
applications.
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 allows
to monitor the measurement without intervening, for example during the plant start-up
