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).
90° 90°
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.
For automatic operation, the rotary switch must be set to "AUTO".
"AUTO" = Automatic 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
