6. Operating Instructions
The TBT7-R1-200-240VAC Time Relay features adjustable dials for setting time ranges (T1 and T2) and percentage adjustments for fine-tuning. The specific function mode is typically selected via a rotary switch or dip switches on the device, which is not detailed in the provided information. Refer to the markings on your specific unit for function selection.
Figure 3: Front panel showing T1 and T2 time setting dials. Each dial has a range selector (1s, 10s, 1m, 10m, 1h, 10h, 1d, 10d, 100d) and a percentage adjustment dial (0-100%).
6.1 Setting Time Ranges (T1 and T2)
The relay features two independent time settings, T1 and T2, which are used for various asymmetric cycle functions. Each setting consists of two dials:
- Range Selector Dial: This dial allows you to select the base time unit (e.g., 1 second, 1 minute, 1 hour, 1 day) and its multiplier (e.g., 1, 10, 100). Available ranges typically include 0.1s-1s, 1s-10s, 10s-1m, 1m-10m, 10m-1h, 1h-10h, 10h-1d, 1d-10d, 10d-100d.
- Percentage Adjustment Dial: Once a range is selected, this dial allows for fine adjustment within that range, typically from 0% to 100%. For example, if the range is set to 1s-10s, setting the percentage dial to 50% would result in a 5-second delay.
Adjust T1 and T2 according to the desired timing sequence for your chosen function mode.
6.2 Function Selection
The relay supports up to 10 different operating functions. The method for selecting these functions (e.g., rotary switch, dip switches, or external wiring configuration) is not explicitly detailed in the provided product information. Please consult the specific markings on your device or the manufacturer's supplementary documentation for detailed instructions on function mode selection.
7. Maintenance
The EQBVZZRD TBT7-R1-200-240VAC Time Relay is designed for minimal maintenance. Follow these general guidelines:
- Keep the device clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Periodically inspect wiring connections to ensure they remain tight and secure.
- Ensure the operating environment remains within the specified temperature and humidity ranges.
- Do not attempt to open or repair the device yourself. Refer to qualified service personnel for any repairs.
8. Troubleshooting
If the time relay is not functioning as expected, consider the following:
- No Power: Check the power supply connections (Un terminals) and ensure the voltage is within the 12V-240VAC/DC range. Verify circuit breakers or fuses.
- Incorrect Timing: Re-check the T1 and T2 dial settings, including both the range selector and the percentage adjustment. Ensure the selected function mode is appropriate for the desired operation.
- Output Not Switching: Verify the load connections to terminals 15, 16, and 18. Ensure the load is within the relay's contact rating (16A / 250V~). Check if the control input (S terminal) is being triggered correctly.
- Intermittent Operation: Inspect all wiring for loose connections or damaged insulation. Ensure the operating environment is stable and free from excessive electrical noise or vibration.
If issues persist after checking these points, contact the manufacturer or a qualified technician for assistance.
