Functions
If the actuator is driven by a 3-position signal from the controller, it generates a rotary
motion which is transferred to the valve (butterfly, slipper valve, three-port or four-port
mixing valve).
Direction of rotation of the actuator on delivery:
• Voltage at Y1 = Clockwise rotation
• Voltage at Y2 = Anti-clockwise rotation
• No voltage
= No rotation; actuator fixed in relevant position

.
.

The direction of rotation can be reversed if required.
Extending the actuator
functions

• The SQK33.00 actuator can be fitted with an auxiliary switch
• The SQL… actuators can be fitted with an auxiliary switch, a dual auxiliary switch or
an auxiliary switch and a 1000-ohm potentiometer.
If an auxiliary switch and/or potentiometer are fitted, the electrical wiring must take
account of this. Refer to the wiring diagram under the actuator cover and see also the
"Commissioning" and "Connection diagrams" sections in this data sheet.

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 nonSiemens 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").

Engineering

• Butterfly valves: see data sheets N4100 … N4199.
• Three-port and four-port slipper valves: see data sheets N4200 … N4299.
• Admissible ambient temperatures, see "Technical data".
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).

Note

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.
For automatic operation, the rotary switch must be set to "AUTO".

Mode of operation
Rotary switch for
mode selection

"AUTO" = Automatic operation

Reversing the
direction of rotation

"MAN" = Manual operation

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").
The wiring for the OPEN and CLOSE control signal is not affected.

As supplied

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

Warning !

Disposal

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.
If necessary, disconnect electrical connections from terminals.

.

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.
