9-10: Chlorine Probe ECL4/5/6/7/12. Max 10ppm. 9(Input Signal, red wire), 10(GND, black wire).
11-12: Current output (0÷20mA o 4÷20mA) proportional to read value. 11(-) ; 12 (+).
13-14-15-16: See the following paragraph.
POWER SUPPLY FUSE PROTECTED (0,2A)
“SEPR” CONFIGURATION.
The instrument is set to work without a proximity sensor. If needed, proximity sensor turns the instrument
into stand-by mode if there isn’t flow. Instrument’s display shows “NO FLOW”.
Connect “SEPR” to blocks 13(blue), 15(black), 16(brown). Connect together block 14 with block 13.
To work without a “SEPR” and with the same functionality use blocks 15 and 16 as a free contact.
Connect together block 14 with block 13.
Using “SEPR” or the free contact, two instruments can be controlled. Connect block 14 and 15 from
master instrument to another instrument “J Digital” (slave). Finally follows the previous described
connections for the master instrument.
* See instrument’s label.
