SYMBOLS AND SAFETY
Please ensure that the detailed operating instructions and the chapter on “Safety” in particular have been read and
understood by all personnel involved in the installation, start-up, operation, maintenance and repair of the actuators.
Beware of mechanical hazards due to electrically powered actuator components! With the actuator powered
electrically, operating the unit holds the danger of crushing your finger!
Caution! During the installation of the actuator on the valve, the unit must not be powered electrically. Disconnect
voltage from the actuator before maintenance and adjustment work.
During adjustment work, the actuator must be operated by means of the handwheel only. Do not operate electrically!
DO NOT FULLY EXTEND.
FUNCTION
The ARIA Series actuators are designed as Spring-Fail-Safe upon
Loss of- Power, or Loss-of-Signal. The actuator is mounted onto
the control valve via pillars and mounting base and attached via
a yoke locknut. The actuator stem and valve stem are connected
as well.
Based on a brushless DC motor (BLDC) the generated torque is
transmitted via a multi-stage spur gear onto a spindle nut. The
spindle nut transmits the input torque into an axial thrust force
via a spindle. The linear stroke is transmitted to the valve spindle
by a coupling piece.
The stroke is measured and controlled by a linear 12 Bit Hall
sensor. In case of mains power loss, the stroke movement is
in OPEN or CLOSE direction by spring force. Electrical wiring is
terminated at a terminal block under the actuator cover.
DANGER SIGNS
Caution!
There is a general risk of damage related to health and/or properties.
Danger!
Electrical voltages are present that may lead to death. Life threatening risks
may occur due to electrical voltages!
Danger!
This sign warns of hazards posing a risk to health. Ignoring these instructions can lead to injuries.
Other notes
• The motor surface temperature may rise when maintaining, inspecting and repairing the actuator immediately after
operation. There is a danger of burning the skin!
• Always consult the relevant operating instructions when mounting ARIA accessories or operating the actuator with
ARIA accessories.
• Connections for signal in- and output are double isolated from circuits that can be under dangerous voltage
