5. Operating Modes (P1-P7)
The module supports seven distinct operating modes, each designed for specific timing control scenarios. "OP" refers to the relay's operating time, and "CL" refers to the relay's closing (off) time. "LOP" refers to the number of cycles.
- P1: After a signal is triggered, the relay closes for the "OP" time. The signal is ineffective during this timing period.
- P2: After a signal is triggered, the relay closes for the "OP" time. If a new signal is triggered during this time, the timer resets and restarts.
- P3: After a signal is triggered, the relay closes for the "OP" time. If a new signal is triggered during this time, the relay opens, and the timing stops.
- P4: When triggered, the relay opens. After a delay, it closes for the "OP" time, then opens again once the time expires.
- P5: The relay operates for "OP" time, then opens for "CL" time, and repeats this cycle "LOP" times. If a signal is received during the cycle, the relay opens, and the timing stops.
- P6: Similar to P5, the relay operates for "OP" time, then opens for "CL" time, and repeats "LOP" times. The signal is ignored during the cycle.
- P7 (Signal Hold Function): The signal is maintained, the timer is canceled, and the relay is driven. When the signal disappears, the relay closes for "OP" time. If another signal is received during this period, the timer is canceled.
6. Parameter Settings
To configure the module's operating parameters:
- Select Working Mode: First, define the desired working mode (P1-P7).
- Enter Setting Interface: Press the SET button to select the working mode and enter the system parameter definition interface.
- Modify Parameters: In the system parameter setting interface, press the SET button to cycle through the parameters (OP, CL, LOP).
- Adjust Values: Use the UP and DOWN buttons to adjust the values of the selected parameter. A long press on UP/DOWN allows for faster adjustment.
- Save Settings: After setting all parameters, press and hold the SET button to save the settings and exit the parameter setting interface.
Note: Modes P1 to P3 are quickly set and may not require all parameters. Mode P7 is invalid for quick setting and requires specific configuration.
7. Troubleshooting
- Module not powering on:
- Check power supply connections (Micro USB or 6-30V terminals).
- Ensure the power supply voltage is within the specified range.
- Relay not activating:
- Verify the trigger signal source and its voltage level.
- Confirm the selected operating mode (P1-P7) and its conditions for relay activation.
- Check the "OP" time setting; it might be set to 0.
- Incorrect timing:
- Review the "OP" and "CL" parameter settings for the chosen mode.
- Ensure the module is receiving a stable power supply.
- Display issues:
- Ensure the module is powered correctly.
- If the display is damaged, contact support.
8. Maintenance
The DollaTek Delay Switching Relay Module is designed for reliable operation with minimal maintenance. Follow these guidelines:
- Cleaning: Use a dry, soft cloth to clean the module. Do not use liquids or abrasive cleaners.
- Environment: Operate the module within the specified temperature range (-40°C to 85°C) and avoid excessive humidity or dusty environments.
- Connections: Periodically check all wiring connections to ensure they are secure and free from corrosion.
- Storage: When not in use, store the module in a dry, cool place, away from direct sunlight and static electricity.
