Manifold sub−bases
The number of electrically controllable valve positions
depends on the manifold sub−bases and on the electrical
connection used (see Tab. 1/3 ... Tab. 1/5).
If only manifold sub−bases that support the control of two
solenoid coils per valve position are used, any type of valve
can be placed in any valve position.
If, on the other hand, only manifold sub−bases that control
only one solenoid coil per valve position are used, the valve
terminal can only be fitted with monostable 5/2−way valves,
identifier M52....
