4. Setup

Follow these general steps for installing the RQR1 Time Relay. Refer to your specific application's wiring diagrams for detailed connections.

1. Mounting: Securely mount the time relay in a suitable enclosure or on a DIN rail, ensuring adequate ventilation.
2. Power Connection: Connect the power supply to terminals A1 and A2 as indicated on the relay. Ensure the voltage matches the relay's specifications.
3. Output Connections: Connect the load to the appropriate output terminals (e.g., 15, 18, 28 for common, normally open, and normally closed contacts, respectively).
4. Verify Wiring: Double-check all wiring connections for correctness and security before applying power.

5. Operating Instructions

The RQR1 Time Relay features two rotary dials for setting the desired time delay.

1. Select Time Range: Use the lower rotary dial (with the silver screw) to select the desired time range. Available ranges typically include:
   • Seconds (e.g., 6-60s)
   • Minutes (e.g., 1-10min, 6-60min)
   • Hours (e.g., 1-10h, 10-100h)
2. Set Time Multiplier: Use the upper rotary dial (with the blue screw) to set the time multiplier within the selected range. This dial typically has markings from 1 to 10. For example, if the range is set to '6-60s' and the multiplier is set to '5', the total time delay will be 30 seconds (50% of 60s, or 5 times the base unit of the range).
3. Apply Power: Once the time settings are configured, apply power to the relay. The relay will begin its timing cycle according to the selected settings.
4. Monitor Operation: Observe the relay's behavior to ensure it operates as expected.

6. Maintenance

The Bolisila RQR1 Time Relay is designed for reliable operation with minimal maintenance. However, periodic checks can help ensure its longevity and performance.

• Cleaning: Keep the relay clean and free from dust and debris. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents.
• Connection Checks: Periodically inspect wiring connections to ensure they remain tight and free from corrosion.
• Environmental Inspection: Ensure the operating environment remains within the specified temperature and humidity limits.
• No User-Serviceable Parts: The relay contains no user-serviceable parts. Do not attempt to open or repair the unit.

7. Troubleshooting

If you encounter issues with your RQR1 Time Relay, consider the following common troubleshooting steps:

• Relay Not Activating:
  • Check power supply connections (A1, A2).
  • Verify the input voltage matches the relay's specifications.
  • Ensure the time settings are correctly configured.
• Incorrect Timing:
  • Recheck the time range and multiplier dial settings.
  • Ensure the load is within the relay's contact rating.
• No Output:
  • Inspect the load wiring connections (15, 18, 28).
  • Confirm the load itself is functional.
• Overheating:
  • Ensure adequate ventilation around the relay.
  • Verify the load current does not exceed the relay's maximum rating.

If problems persist after attempting these steps, contact Bolisila customer support or a qualified technician.
