• Range of Application: AUMA actuators are intended for industrial valves such as globe, gate, butterfly, and ball valves. Usage beyond these applications is at the user's risk.
• Commissioning: Special regulations must be followed for hazardous areas, and electrical work should be performed by qualified personnel.
• Maintenance: Follow maintenance instructions to ensure safe operation.
• Warnings and Notes: Non-compliance can lead to injuries or damage. Qualified personnel should be familiar with all warnings.

The AUMA multi-turn actuators SAExC 07.1 – SAExC 16.1 are modular, driven by an electric motor, and controlled by AMBExC 01.1. They include limit switches for travel limitation and torque switches for the end position CLOSED.

• Explosion Protection: Various standards and options for flameproof enclosures.
• Type of Duty: Short-time duty S2 for 15 or 30 minutes.
• Motors: 3-phase AC asynchronous motor with insulation class F.
• Limit Switching: Options for single, tandem, or triple switches.
• Torque Switching: Adjustable for OPEN and CLOSE directions.
• Position Feedback: Options for potentiometer or 0/4 – 20 mA signals.
• Manual Operation: Manual drive available for emergency operation.
• Service Conditions: Enclosure protection IP 67 or IP 68, with options for corrosion protection.

• Transport in sturdy packaging and store in a dry, ventilated area.
• Protect against corrosion if stored for more than 6 months.

• Check for damage before mounting and replace damaged parts with original spares.
• Consult AUMA if temperatures above 40°C are expected at the valve flange or stem.

The multi-turn actuator is delivered in the CLOSED position with specific output drive types (B1, B2, B3, B4) featuring bore and keyway according to ISO 5210. Type A requires matching the internal thread of the stem nut with the valve stem thread. Fastening torque for bolts is specified in Table 3, with strength class 8.8.

Ensure the mounting flange fits the valve/gearbox. Degrease mounting faces and apply grease to the input shaft. Fasten the actuator using bolts of at least quality 8.8. For output drive type A, finish machining of the stem nut is required, including drilling, boring, and threading.

Manual operation is engaged via a change-over lever on the handwheel. Excessive force should be avoided to prevent damage. Manual operation disengages automatically when the motor starts.

Follow European Standards EN 60079-14 and EN 60079-17 for hazardous areas. Electrical connections are made using Ex-plug/socket connectors or Ex-plug-in terminal connections, ensuring enclosure protection IP 67 or IP 68. Technical data for connections are provided in Tables 5 and 6.

Thermoswitches protect against overheating. Bypassing motor protection voids explosion protection approval. Remote position transmitters require screened cables.

Opening the switch compartment requires ensuring no explosive gas or voltage is present. Removal of the cover and indicator disc is necessary for settings.

Settings for end positions CLOSED and OPEN involve turning the handwheel and adjusting setting spindles with a screwdriver. Intermediate position switches can be set for specific applications.

Figures illustrate various components and procedures, such as output drive types, connection methods, and control units. Tables provide torque specifications and technical data for electrical connections.

1. Setting for Direction OPEN: Use a screwdriver to turn the setting spindle in the direction of the arrow to set the valve to an intermediate position.
2. Setting of the Torque Switching: Adjust the torque dial to match the valve's requirements, ensuring changes are approved by the valve manufacturer.
3. Test Run: Ensure no explosion risk exists before working on the actuator. Check the direction of rotation and verify limit switching settings.
4. Setting of the Potentiometer: Adjust for remote indication by moving the valve to the CLOSED position and fine-tuning the zero point externally.
5. Setting of Electronic Position Transmitter RWG: Connect the voltage and adjust the potentiometer to ensure the output current is within the specified range.
6. Setting of the Mechanical Position Indicator: Install the indicator disc on the shaft and align it with the cover mark.
7. Closing the Switch Compartment: Ensure sealing faces are clean and the O-ring is in good condition before replacing the cover.
8. Controls AUMA MATIC BASIC ExC: Ensure no explosion risk exists before working on the actuator. Adjust the type of seating in the end position CLOSED as per the valve manufacturer's instructions.
9. Push-to-Run Operation: Factory settings can be changed by adjusting jumpers on the control board for LOCAL and REMOTE operations.
10. Settings on Relay Board: Assign functions to terminals using jumpers for potential-free feedback.
11. Fuses: Ensure no explosive gas or voltage is present before accessing fuses. Replace fuses with identical values.

The document provides detailed specifications for fuses used in actuator controls AMBExC 01.1, including sizes and control voltages for power supply units at 115 V and 230 V.

Regular inspections and maintenance are required every three years by qualified personnel, following the European standard EN 60079-17. Key tasks include visual inspections for damage, checking cable integrity, and ensuring tightness of cable entries.

The gear housing is pre-filled with lubricant, with grease changes recommended every 10-12 years if operated seldom, or every 6-8 years if operated frequently.

AUMA actuators should be disassembled and sorted by material type for recycling when necessary. Greases and oils must be collected and disposed of according to environmental regulations.

AUMA offers extensive services for maintenance and inspection. A comprehensive spare parts list is provided, emphasizing the use of original parts to maintain warranty and liability coverage.

For seldom-used actuators, a test run every six months is advised. Bolts between actuator and valve/gearbox should be checked annually for tightness.

The document includes a declaration of conformity and incorporation, ensuring compliance with relevant standards.
