5.2. ഓപ്പറേറ്റിംഗ് മോഡ് സജ്ജമാക്കുന്നു
While in the setup interface, use the UP or താഴേക്ക് buttons to cycle through the available operating modes. The trigger is set to detect a change from LOW to HIGH. If the trigger remains ON, it will only time once for modes requiring a trigger.
- P1.1: Delay OFF
- When triggered, the output is ON for the "OP" time. After "OP" time, the output turns OFF.
- If triggered again during timing, there is no effect until the current timing cycle is complete.
- P1.2: Delay ON-OFF (Restart)
- When triggered, the output is ON for the "OP" time. After "OP" time, the output turns OFF.
- If triggered again during timing, the "OP" time restarts from the beginning.
- P1.3: Delay ON-OFF (Clear)
- When triggered, the output is ON for the "OP" time. After "OP" time, the output turns OFF.
- If triggered again during timing, the timer resets to "000" and the output turns OFF immediately.
- P1.4: Power-On Delay OFF
- When the board is powered on, the output is ON for the "OP" time. After "OP" time, the output turns OFF.
- No external trigger is required for this mode.
- P2.1: Trigger OFF then ON (No Restart)
- When triggered, the output is OFF for the "CL" time, then ON for the "OP" time. After "OP" time, the output turns OFF.
- If triggered again during timing, there is no effect until the current timing cycle is complete.
- P2.2: Trigger OFF then ON (Restart)
- When triggered, the output is OFF for the "CL" time, then ON for the "OP" time. After "OP" time, the output turns OFF.
- If triggered again during timing, the cycle restarts from the "CL" time.
- P3.1: Cycle ON-OFF (Triggered)
- When triggered, the output is ON for "OP" time, then OFF for "CL" time. This cycle repeats for the number of "LOP" times set.
- If triggered again during the cycle, the output turns OFF and the timer clears.
- P3.2: Cycle ON-OFF (Power-On)
- When the board is powered on, the output is ON for "OP" time, then OFF for "CL" time. This cycle repeats for the number of "LOP" times set.
- No external trigger is required for this mode.
- P-4: Signal Holding Relay ON
- When triggered, the output is ON for the "OP" time. After "OP" time, the output turns OFF.
- If triggered again during timing, the timer resets.
- കുറിപ്പ്: If the trigger signal is held, the timing will stay at the start until the trigger is released.

7. പ്രശ്നപരിഹാരം
If you encounter issues with your Walfront Digital LED Relay Board, refer to the following common problems and solutions:
- Module Does Not Power On / Display is Blank:
- പവർ സപ്ലൈ പരിശോധിക്കുക: Ensure the DC 5-36V power supply is correctly connected to the GND and V+ terminals and is providing the correct voltage.
- വയറിംഗ് പരിശോധിക്കുക: Verify that the power wires are securely connected and there are no short circuits.
- സ്ലീപ്പ് മോഡ്: The display might be in "C-P" (sleep) mode. Press any button to wake it up.
- Relay Does Not Activate / Load Does Not Turn On:
- Check Output Wiring: Ensure the load is correctly connected to the OUT- and OUT+ terminals.
- Verify Relay Enable Mode: Check if the relay is set to "OFF" (prohibits conduction) using the STOP button. Set it to "ON" if necessary.
- Review പ്രോഗ്രാമിംഗ്: Double-check the selected operating mode (P1.x, P2.x, P3.x, P-4) and ensure the "OP" (ON time) is set correctly and is not zero.
- ട്രിഗർ സിഗ്നൽ: If using a trigger-dependent mode, ensure the trigger signal is correctly applied to the SIGN terminal and is within the DC 3-24V range.
- ലോഡ് അനുയോജ്യത: Ensure the connected load's current draw does not exceed the module's 15 Amp റേറ്റിംഗ്.
- Timer Does Not Count Down / Behaves Unexpectedly:
- Re-enter Programming: Go back into the setup interface (hold SET button) and re-verify all parameters (OP, CL, LOP) and the selected operating mode.
- സമയ സ്കെയിൽ: Ensure the time scale (seconds, 0.1 seconds, minutes) is correctly set for your desired timing.
- Trigger Behavior: For trigger-dependent modes, understand how repeated triggers affect the timing (restart, no effect, clear). Refer to Section 5.2.
- Display Turns Off After 5 Minutes:
- This is normal behavior if the module is in "C-P" (sleep) mode. Press any button to reactivate the display. If you prefer the display to stay on, change the sleep mode to "O-d" (Normal Mode) as described in Section 5.5.
