• Power Consumption: 4.1 VA (for 0.85 D), 4.8 VA (for 0.85 Y).
• Weight: 1.3 kg.

Special Smart Functions (for ARI-PACO® 0.85 Y):

1. Automatic Travel Adaptation: Real-time adjustment of valve travel during the initial start-up.
2. Direct Control: Open/stop/close priorities ensure manual mode has the highest priority.
3. Manual Mode Switching: Automatic switch to manual mode for safety, with internal magnetic switch to return to automatic mode.
4. Variable Control and Feedback Signals: Control signal can be switched between 0-10V or 2-10V, with inversion options.
5. Wearless Actual Value Sensing: Position determined from wearless reed contacts.
6. Non-contact Motor Travel Switching: Electronic switching for travel in final positions.
7. Valve Blocking Protection: Periodically opens the valve to prevent sticking due to long periods of inactivity.
8. Error Detection: Detects valve blocking and attempts to eliminate it by activating moving commands.
9. Dynamic Hysteresis: Suppresses control signal interference for reduced wear and longer actuator life.
10. Zero Crossing: Ensures accurate operation by connecting neutral lines in the DC control signal and AC power input.

Applications:

• ARI-PACO® 0.85 D/Y actuators are suitable for controlling valves in systems requiring precise adjustment of valve position, particularly in industrial environments.

Accessories:

• Additional Limit Switches: Two changeover contacts with zero-potential switching capacity.
• Potentiometer: For manual adjustment of position.
• Switch Board: Optional, for additional limit switches or error message switches.

Wiring Diagrams and Dimensions:

• Control Signals: Include a jumper connection for priority switching in automatic or manual operation.
• Dimensions: 145 mm x 95 mm x 242 mm for the actuator body.

Function and Error Indication:

• LED Indicator: Provides visual feedback on actuator status (e.g., steady LED for automatic mode, blinking for initialization or error detection).
