pH electrode
Connect the internal wire of the electrode cable to terminal (+) and the screening
of the cable to terminal (-) of CHAN1. Ground loops can be avoided by immersing
an earthing rod in the process liquid close to the electrodes. Connect it only to
terminal (M)!
mV electrode
Connect the internal wire of the electrode cable to terminal (+) and the screening
of the cable to terminal (-) of CHAN2.
Temperature probe, Pt1000 (or Pt100)
Connect the internal wire of the electrode cable to terminal (+) and the screening
of the cable to terminal (-) of C1.
Free chlorine electrode
Connect the internal wire of the electrode cable to terminal (+) and the screening
of the cable to terminal (-) of C2.
Recorder
Two recorders, one for each channel, can be connected to the (+) and (-) terminals
of (OUT1) and (OUT2). Max. impedance = 300 Ω.
Relays
There are four relays (REL1...REL4) with voltage-free contacts. Connect their
two contacts in series with the load. The ratings of the connected load should lie
between 12...250 V~, maximum 0.5 A.
Mains
Connect phase to terminal (P), neutral to terminal (N), and earth to earthing
terminal.
Very important
1. All electrodes should be positioned in a suitable bypass vessel such as model
S404C.
2. Keep the speed of the water flow through the bypass vessel as constant as pos-
sible (at least 20 cm/s).
3. Verify that other devices do not generate electric current through the water.
4. The response of the dosing system will be affected by the time required to
disperse the reagents and their arrival at the measuring point.
• Always short circuit the unused pH/mV input terminals!
• Special care should be taken when connect-
ing a typical pH/mV/Ion coaxial cable. Make
sure that all parts are dry and clean and do
not forget to remove the black antistatic foil
between the inner lead and the outer screen-
ing!
RS485
Only use twisted pair UTP cable to connect up to 31 controllers to a computer!
