Electrical Connections
Power supply: 230 V~ 50/60 Hz.The mains circuit must be protected in accordance
with the relevant laws and regulations. Typically, the protection is given by a 30 mA
differential switch and a breaker or 1 A fuse.
● If a level control sensor is used, plug it to its connector (see figure).
Warning! If several pumps are connected in parallel, always observe the polarity of
the level connection to not endanger the proper functioning of the system or damage
the inputs!
● Connect the measurement electrode to the BNC connector.
Functional Description of the System
Display: during normal operations displays the measured pH or redox (mV); the
following messages may also appear:
● OFF: the pump has been disabled by pressing the ON/OFF button.
● LEU: the level sensor consent is missing.
● PAU: the pump is "Paused" at start-up (also see "Configuration"
section).
● ALL: a dosage "Alarm" is active (also see "Configuration" section).
● UR: measurement out of range below the minimum value
(Under-Range).
● OR: measurement out of range above the maximum value
(Over-Range).
