SAS31.. and SAS81..
3-position actuators must have their own specific controller, see "Conenction Diagrams".
SAS61..
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.
SAS61../MO
The Modbus converter is dimensioned for analog control at 0…10 V.
Note: Keep the analog signal setting on the actuator as is (switch 1 to Off); adjustment not
possible.
The actuators are parameterized at the factory to an equal-percentage characteristic; this
corresponds to their use with valves VVG/VXG44.
When using SAS61../MO with valve series VVG549, the following must be set:
· Actuator: DIL switch (internal actuator characteristic changeover) to linear
(switch 2 to On).
· Modbus register 263: Set "Y_U_Characteristic" to “0 = linear".

1)
Only together with weather shield ASK39.2. IP54 housing protection unchanged.
SAS61../MO is not intended for outdoor use.
Maintenance
The SAS.. actuators are maintenance-free.
Mounting:
● Do not touch the valve coupling if the components (valve/pipes) are hot
● If necessary, disconnect electrical connections from the terminals
The actuator must be correctly fitted to the valve before recommissioning.
