Siem ens Modulating control valves with magnetic actuators, PN 16 CE2N4461en
Building Technologies 2018-02-05
If the positioning signal is interrupted, or in the event of a power failure, the valve’s
return spring will automatically close control path A ↑ AB.
By pressing (a) and turning (b) the hand wheel
∂ in clockwise (CW) direction, control path A ↑ AB can be
mechanically opened to between 80 and 90 %
∂ in counterclockwise (CCW) direction, the actuator will be
switched off and the valve closed
As soon as the hand wheel is pressed and turned, neither the
forced control signal Z nor the input signal Y or the phase-cut
signal acts on the actuator. The green LED will flash.
For automatic control, the hand wheel must be set to the Auto
position. The green LED will be lit.
