4. Налаштування та встановлення
Proper installation is critical for the correct functioning of the V-9012-1 Solenoid Relay.
4.1. Перевірки перед встановленням
- 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. Монтаж
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. Інструкція з підключення
Виконайте такі кроки для електричних з’єднань:
- Ensure the power source is completely disconnected.
- Connect the positive (+) 12 VDC power supply wire to BO TERM. 1 (RED).
- Connect the negative (-) 12 VDC power supply wire to BO TERM. 2 (BLK). Note that this terminal includes a resistor.
- Переконайтеся, що всі з’єднання надійні та належним чином ізольовані.
4.4. Pneumatic Connections
Follow these steps for pneumatic connections:
- Connect the main pneumatic supply line to the port labeled ПОСТАЧАННЯ. Ensure the supply pressure is within the device's specified operating range.
- Connect the line leading to the pneumatic actuator or controlled device to the port labeled АКТУАТОР.
- Check all pneumatic connections for leaks after pressurizing the system.
5. Операція
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.
