F1: General fuse (6.3AT)
F2: Circuit fuse (3.15AT)
Main power supply (from 90VAC to 265VAC):
L (live), E (earth), N(neutral)
Setpoint Outputs
(voltage output is the same as for main power supply):
1 - E - N (F1 fuse protected) D1 pH
2 - E - N (F1 fuse protected) Inhibitor
3 - E - N (F1 fuse protected) D1 mV (Biocide 1)
4 - E - N (F1 fuse protected) Biocide 2
5 - E - N (F1 fuse protected) Pre-biocide 1
6 - E - N (F1 fuse protected) Pre-biocide 2
Bleed Valve (Free Voltage Version): 7(N.C.), 8(C), 9(N.O.) Free Voltage contact
General Alarm output: 10(N.C.), 11(C), 12(N.O.) Free Voltage contact
