2.3.2 Connection of the power supply
Connect the power supply to terminal 1 (earth), terminal 2 (zero) and terminal 3 (live).
2.3.3 Connection of dosing pumps and valves ( control outputs )
Connection to relay output 1 (X1) is made through terminal 4 and terminal 6, connection to relay
output 2 (X2) is made through terminal 7 and terminal 9, connection to relay output 3 (L1) is made
through terminal 10 and terminal 12 and connection to relay output 4 (L2) is made through terminal 13
and terminal 15.
2.3.4 Connection to an external alarm

2.3.5 Connection of the electrode
Electrode cabling is a very critical part for the safety and accuracy in measuring.
•
Use a low noise coax cable between the electrode and the input terminal on the controller.
•
Low noise cables has, in general, a black semi-conductive sheath between the centrewire
insulation and the shield. Remove this sheath.
•
Keep the cable away from power wires.
•
Max recommended length of cable is 10 meters.
•
Connect the centre ( metal pin ) of the coax cable to terminal 19 ( ELCT + ).
•
Connect the shield ( reference ) of the coax cable to terminal 20 ( ELCT - ).
NOTE! When using PtPK/G (Cr-instrument) do as follow:
•
connect the shield ( reference ) of the coax cable to terminal 19 ( EL+ )
•
connect the centre ( metal pin ) of the coax cable to terminal 20 ( EL- )
