2. Safety Information
Always adhere to local codes and regulations during installation and operation. Disconnect power before servicing. Ensure proper grounding. Installation should be performed by qualified personnel only.
- Read all instructions carefully before installation or operation.
- Wear appropriate personal protective equipment (PPE).
- Verify system pressure and electrical ratings are within the device's specifications.
- Do not modify the device.
3. Setup and Installation
Proper installation is crucial for the reliable operation of the PS10-1 pressure switch. Follow these general guidelines:
- Mounting: Select a suitable location where the switch is protected from physical damage and environmental extremes. Ensure the mounting surface is stable.
- Pressure Connection: Connect the threaded connector of the PS10-1 to the system's pressure port. Use appropriate thread sealant to prevent leaks. Do not overtighten.
- Electrical Wiring:
- Ensure all power is disconnected before wiring.
- Open the switch housing to access the terminal block.
- Connect the electrical wires according to the system's wiring diagram and local electrical codes. The PS10-1 is an SPDT switch, meaning it has common, normally open (NO), and normally closed (NC) contacts.
- Secure all connections firmly using the screw terminals.
- Close the housing securely to maintain its IP54 rating.
- Testing: After installation, slowly pressurize the system and verify the switch operates as intended at the specified set point.
4. Operating Principles
The POTTER PS10-1 is an automatic pressure switch designed to detect changes in waterflow pressure. Its internal mechanism responds to pressure fluctuations, actuating the SPDT contacts. The default contact type is Normally Closed (NC), meaning the circuit is closed when the pressure is below the set point and opens when the pressure rises above it, or vice-versa depending on the specific application and wiring. The switch provides a reliable electrical signal based on the detected pressure condition.
5. Maintenance
The PS10-1 pressure switch is designed for minimal maintenance. However, periodic checks are recommended to ensure continued reliable operation.
- Visual Inspection: Regularly inspect the switch for any signs of physical damage, corrosion, or loose connections.
- Functionality Test: Periodically test the switch's operation by simulating a pressure change to verify it actuates correctly. Refer to system-specific testing procedures.
- Cleaning: Keep the exterior of the switch clean and free from dust or debris. Do not use harsh chemicals.
- Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity ranges.
6. Troubleshooting
If the PS10-1 pressure switch is not functioning as expected, consider the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
