Information on accessories such as stem protection tubes is provided, including assembly instructions and material specifications.
1. Mechanical Assembly
Ensure the protective cap for the stem protection tube is in perfect condition and securely attached. For protection tubes exceeding 2 meters, secure them with appropriate support to prevent bending or oscillation.
2. Electrical Connection
2.1 Basic Information
Electrical connections must be performed by qualified personnel. Ensure that the current type, mains voltage, and frequency match the actuator controls and motor name plates. Short-circuit protection and disconnect switches must be provided by the customer.
2.2 Wiring and Protection
Refer to the wiring diagram attached to the device. Use fuses and disconnect switches for short-circuit protection. Adapt switchgear sizing to the maximum current and select overcurrent protection devices accordingly.
2.3 Cable Installation
Use cables according to rated current and ensure they are voltage-proof. For outdoor installations, use UV-resistant cables. Lay cables susceptible to interference away from interference sources.
2.4 Wall Bracket and Control Box Installation
When actuator controls are mounted separately, ensure the cable length does not exceed 100 meters. Use screened cables for position transmitters and ensure proper earthing.
3. Motor Connection
Disconnect the device from the mains before opening the motor connection compartment. Use cable glands suitable for the type of protection and ensure proper enclosure protection. Connect all protective earth conductors before starting the device.
4. Terminal Compartment
Open the terminal compartment by removing the cover and insert suitable cable glands. Seal unused cable entries with approved plugs. Ensure all protective earth conductors are connected to prevent electric shock.
5. Actuator Controls Connection
For KP/KPH connections, use screw-type terminals for power and control contacts. Ensure the terminal compartment is designed for increased safety and that the flameproof interior remains sealed when connecting cables.
Tightening torques for terminal cross sections are specified for different types of connections. For power contacts (U1, V1, W1) and protective earth (PE), the torque is 0.9 – 1.1 Nm with small clamp washers for 1.5 – 4.0 mm² cables, and 2.5 – 6 mm² with large clamp washers. Control contacts require 0.5 – 0.7 Nm for 0.75 – 1.5 mm² cables.
1. Remove cable sheathing (120 – 140 mm).
2. Insert wires into cable glands and fasten with specified torque.
3. Strip wires (controls max. 8 mm, motor 12 mm).
4. Use wire end sleeves for flexible cables.
5. Connect cables as per wiring diagram.
6. Ensure protective earth conductors are connected before device operation.
Ensure all protective earth conductors are connected to avoid electric shock. Use appropriate cable glands and plugs to maintain enclosure protection. For flameproof enclosures, handle with care to avoid damage.
For shielded cables, link the cable shield end to the housing for earthing. Use non-acidic grease on O-rings and ensure they are in good condition.
For KES electrical connections, use terminal blocks for power and control contacts. Ensure the correct type of protection (Ex e or Ex d) is used for cable glands.
Manual operation is possible for setting and commissioning. Engage manual operation only during motor standstill. Local operation is performed using push buttons, and remote operation is possible via control commands or setpoints.
Indication lights show end positions and fault signals. Optional mechanical position indication is available.
Feedback signals via output contacts indicate actuator operation modes. Analogue position feedback is available if equipped with a position transmitter.
Set the selector switch to 0 (OFF) before switching on the power supply. Consider heat-up time for low temperature versions.
- For –40 °C: 5 minutes
- For –60 °C: 40 minutes
- Loosen screws and remove cover.
- If present, remove indicator disc using a spanner with a soft object to avoid paint damage.
- Set torque switches to prevent valve damage.
- Adjust torque dials to required settings (e.g., 250 Nm for CLOSE, 200 Nm for OPEN).
- Maximum tightening torque for lock screws: 0.3 – 0.4 Nm.
- Engage manual operation and adjust setting spindles for CLOSED and OPEN positions.
- Ensure pointers align with marks after adjustments.
- Check direction of rotation and limit switching.
- Correct any incorrect settings before proceeding.
- Ensure all optional equipment is set before closing.
- Clean sealing faces and check O-ring condition.
- Potentiometer: Set for travel sensor and valve position.
- RWG Electronic Position Transmitter: Set for 4 – 20 mA current signal.
- Intermediate Positions: Set using DUO limit switching.
- Mechanical Position Indicator: Align symbols with marks on cover.
- Factory settings may need adjustment for different applications.
- Ensure correct type of seating and other settings as per valve manufacturer’s consent.
