·
Internal auxiliary pilot air is branched centrally from sup
ply connection 1 for all valve solenoid coils. This also
applies if the CPV−SC valve terminal is operated with
different pressure zones (see section Pressure zones").
External auxiliary pilot air If the supply pressure lies between − 0.9...3 bar, you can oper
ate the pilot control of the valve solenoid coils with external
auxiliary pilot air.
Please note
Use regulated external auxiliary pilot air (3...7 bar).
Reliable faultless operation of the CPV−SC valve terminal
is then possible, even with fluctuating operating
pressure.
Please note that the regulated external auxiliary pilot air
for all the valve sub−bases is supplied via the left−hand
end plate. This also applies if the CPV−SC valve terminal
is operated with different pressure zones (see section
Pressure zones").
If your CPV−SC valve terminal is fitted with valve sub−
bases with Ident. code J (5/2−way valves), the external
pilot air must be set to correspond with the supply pres
sure at which the valve is operated (see diagrams).
