Detailed Informations about the New Generation actuators can be found in the Basic
documentation for actuators (P4040).
3-position actuators must have their own specific controller, refer to "Connection
Diagrams" (page 8).
Up to 10 actuators can drive in parallel on a controller output with a rating of 1 mA.
Modulating actuators have an input impedance of 100 kΩ.
Indoor use
With valves whose stem is retracted in the fully closed position, "direct acting" means
that the valve is fully closed (100 %) when positioning signal Y = 0 V and Z = 0 Ω re-
spectively.

Acting direction: direct
The actuators are maintenance-free.
