The direction of rotation of these types of
actuators for opening is counterclockwise.
The direction of rotation can
be reversed by
repositioning a connector
located under the cover.
The wiring for the OPEN
and CLOSE control signal
is not affected

Direction of rotation reversed
If the direction of rotation needs reversing, simply change the connections Y1/Y2.
The 0...90
°
angle of rotation for the end switches is factory-set and cannot be changed.
The potential-free auxiliary switches have adjustable switching points.
Every actuator must be driven by a dedicated controller (refer to
«
Connection
diagrams
»
).
Maintenance
The actuators and butterfly valves require no maintenance.
Before performing any service work on the valve or actuator:
•
Switch off the pump and power supply
•
Close the main shut-off valves in the pipework
•
Release pressure in the pipes and allow them to cool down completely
If necessary, disconnect electrical connections from terminals.
The valve must be re-commissioned only with the manual adjuster or the actuator
correctly assembled.
Disposal
The actuator contains electrical and electronic components and must not be disposed
of together with domestic waste.
Legislation may demand special handling of certain components, or it may be sensible
from an ecological point of view.
Current local legislation must be observed
.
Warranty
The technical data given for these applications is valid only in conjunction with the
Siemens butterfly valves as detailed under
«
Equipment combinations
»
. The use of third-
party valves other than those recommended by Siemens invalidates the warranty.
