Mechanical design  
The electric actuators require no maintenance. They have a reversible synchronous  
motor and reduction gears with self-lubricating sinter bearings. The housing base and  
the console are die-cast aluminium, and the cover is plastic.  
"AUTO" and "MANUAL" modes can be selected with a rotary switch on the housing  
base. When the switch is set to "MANUAL", the actuator and valve can be operated  
with a manual lever. For manual operation, the angle of rotation is mechanically limited  
by an end-stop.  
The actuators supplied have a 90° angle of rotation suitable for the Siemens valves.  
During automatic operation, rotation is limited by two built-in end-switches. For non-  
Siemens valves, the angle of rotation in the range 70° to 180° can be selected by  
repositioning the switching cams.  
The direction of operation of the actuator can be reversed (refer to "Commissioning").

.
Electrical installation  
The actuators must be electrically connected in accordance with local regulations and  
with the connection diagrams.  
Regulations and requirements to ensure the safety of people and property must  
be observed at all times.  
!
If additional functions are to be controlled by the actuator, the ASC9.. (auxiliary switch)  
or ASZ7.5 (auxiliary switch / potentiometer) must be fitted. The relevant switching  
point(s) and zero-ohm position must be noted in the plant documentation.

Mounting  
Mounting instructions are enclosed with the mounting kit.  
The valve, actuator and mounting kit are packed separately. The valve and actuator  
can be assembled easily on site. There is no need for special tools or calibration.  
Take care to install the valve the right way up. Refer to the mounting instructions for the  
valve concerned (butterfly or slipper valves).

Commissioning  
When commissioning the complete motorised valve, consisting of actuator, mounting kit  
and (butterfly or slipper) valve, check the wiring and test the functions. This also  
applies to any additional components fitted (e.g. auxiliary switch or potentiometer).  
Siemens slipper valves up to DN50 can be commissioned without an actuator being  
fitted. In this case, the flow rate must be adjusted manually with the standard manual  
adjuster fitted to the valve.  
Note  
For automatic operation, the rotary switch must be set to "AUTO".  
Mode of operation

mode selection  
"AUTO" = Automatic operation  
"MAN" = Manual operation  
Reversing the  
The actuators are factory-set to rotate in a clockwise direction (as seen from the front).  
The direction of rotation can be reversed by repositioning a connector located under the  
cover (see "Mechanical design").

Setting the angle of  
rotation  
The angle of rotation is factory-set to 90°. However, the angle can be changed to  
between 70° and 180°. This may be necessary when using non-Siemens valves.  
Special notes on this subject will be found in the mounting instructions for the ASK40  
and ASK41 (mounting kits for non-Siemens valves).  
Maintenance  
.
The actuators require no maintenance.  
When servicing the valve and/or actuator: switch OFF the pump and power  
supply, close the main shut-off valve in the pipework, release pressure in the  
pipes and allow them to cool down completely.  
Warning !  
If necessary, disconnect electrical connections from terminals.  
Disposal  
The device may not be disposed of together with domestic waste. This applies in  
particular to the PCB.  
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 valves (butterfly and slipper valves) and third-party valves for use with the  
ASK40 / ASK41, as described under "Compatibility". The use of third-party valves  
other than those recommended by Siemens invalidates the warranty.
