Modulating control
Rotary direction
Clockwise or counter-clockwise direction depends..
..on the type of control. With no power
applied, the rotary actuator remains in the
respective position.
..on the setting of the rotary direction
DIL switch clockwise / counter-
clockwise
NC (normally closed) ball valve
NC (normally closed) ball valve
Signal on Y1
– rotation counter-clockwise
– ball valve opens
Signal on Y2
– rotation clockwise
– ball valve closes
DIL 2 set to “counter-clockwise”
Flow = 0% at Y = 0 V
Flow = 100% at Y = 10 V
NO (normally open) ball valve
NO (normally open) ball valve
Signal on Y2
– rotation clockwise
– ball valve closes
Signal on Y1
– rotation counter-clockwise
– ball valve opens
DIL 2 set to “clockwise”
Flow = 100% at Y = 0 V
Flow = 0% at Y = 10 V
Position
indication:
Mechanical
Rotary angle position indication by a position indicator/hand lever.
Position
indication:
Electrical
Output voltage U = DC 0...10 V is
generated proportional to the rotary
angle.
U depends on the rotary direction of
the DIL switch setting.
Manual
adjustment
The rotary actuator can be manually adjusted by pressing the gear train
disengagement button.
Equipment combinations
The rotary actuators are suitable for operation of the following Siemens ball valves:
