Connections to the motherboard
Before performing any operation on the terminal board of the instrument, it is mandatory to disconnect it from the mains. To
facilitate the connections to the motherboard, it has been divided into two blocks: electrical connections and I/O connections.
Electrical connections:
F1: Main fuse (6.3AT)
F2: Instrument fuse (3.15AT)
MAIN POWER SUPPLY (115VAC / 240VAC): L(Phase), E(Earth), N(Neutral)
MOTORIZED VALVE OPENING CONTROL: 6(OPEN/GREEN) - A(PHASE/BROWN) - B(NEUTRAL/BLUE)
SET-POINT OUTPUTS (115VAC TO 240VAC):
(free contact outputs are not protected with a fuse and isolation between the outputs and the power supply is 250V MAX):
1 - E - N (F2 Fuse-protected) OUT HCl
2 - E - N (F2 Fuse-protected) OUT NaClO
2
3 - E - N (F2 Fuse-protected) OUT H
2
O
DIOXIDE LEVEL INTO STORAGE TANK:
7(N.C. for no dioxide), 8(C), 9(N.O. for dioxide) Free contact
GENERAL ALARM OUTPUT:
10(N.C.), 11(C), 12(N.O.) Free contact
