4. Opsætning og installation

Proper installation is critical for the correct functioning of the V-9012-1 Solenoid Relay.

4.1. Kontrol før installation

• Verify that the power supply matches the device's requirements (12 VDC).
• Inspect the device for any visible damage from shipping.
• Ensure all necessary tools and fittings are available.

4.2. Montering

Mount the solenoid relay securely in a location that is free from excessive vibration, moisture, and extreme temperatures. Ensure adequate space for wiring and pneumatic connections.

4.3. Ledningsinstruktioner

Følg disse trin for elektriske forbindelser:

1. Ensure the power source is completely disconnected.
2. Connect the positive (+) 12 VDC power supply wire to BO TERM. 1 (RED).
3. Connect the negative (-) 12 VDC power supply wire to BO TERM. 2 (BLK). Note that this terminal includes a resistor.
4. Kontroller, at alle forbindelser er sikre og korrekt isolerede.

4.4. Pneumatic Connections

Follow these steps for pneumatic connections:

1. Connect the main pneumatic supply line to the port labeled LEVERE. Ensure the supply pressure is within the device's specified operating range.
2. Connect the line leading to the pneumatic actuator or controlled device to the port labeled AKTUATOR.
3. Check all pneumatic connections for leaks after pressurizing the system.

5. Betjening

The V-9012-1 Solenoid Relay operates based on the applied electrical input voltage, controlling the pneumatic output to the actuator.

• +12 VDC Input: When a positive 12 VDC is applied to the input terminals, the relay will enter a 'PRESS' state, allowing supply pressure to flow to the actuator.
• 0 VDC Input: When 0 VDC (no voltage) is applied, the relay will enter a 'HOLD' state, maintaining the current pneumatic output.
• -12 VDC Input: When a negative 12 VDC is applied, the relay will enter an 'EXHAUST' state, releasing pressure from the actuator.

Ensure that the control system provides the correct voltage signals for the desired pneumatic response.

6. Vedligeholdelse

The Johnson Controls V-9012-1 Solenoid Relay is designed for reliable operation with minimal maintenance. However, periodic checks can help ensure longevity and optimal performance.

• Rutinemæssig inspektion: Periodically inspect the device for any signs of wear, corrosion, or damage to the housing, wiring, and pneumatic connections.
• Rensning: Keep the exterior of the device clean and free from dust and debris. Do not use harsh chemicals or abrasive cleaners.
• Forbindelsesintegritet: Verify that all electrical and pneumatic connections remain tight and secure.
• Professionel service: For internal issues or complex repairs, contact a qualified service technician or Johnson Controls support. Do not attempt to disassemble the unit.
