6. Operation

6.1. Display Interface and Buttons

Diagram showing the display interface with PV (Process Value) and SV (Set Value) displays, ON/OFF indicator, and buttons: Up, Down, SET, and STOP/START (Restart). — Figure 12: Display Interface and Code Setting

PV (Process Value): Displays the current timing value (T1).
SV (Set Value): Displays the set timing value (T2).
ON/OUT LED: Indicates relay status.
SET Button: Enters/confirms setting modes.
Up/Down Buttons: Adjust values.
Restart Button: Long press to restart. Double click to Stop/Run.

6.2. Setting Time Parameters (T1, T2)

Press the SET key once to enter the time setting mode. The red digital tube (PV) will flicker, indicating T1 setting.
Use the Up (+) or Down (-) buttons to adjust the desired value for T1.
After setting T1, short press the SET button again. The digital tube (SV) will flicker, indicating T2 setting.
Use the Up (+) or Down (-) buttons to adjust the desired value for T2.
After setting T2, press the SET button again, or wait for 6 seconds. The system will automatically save the memory settings.

6.3. Parameter Setting Mode (P0, P1)

To access advanced settings, long press the SET button. This enters the parameter setting mode, allowing you to select P0 or P1 parameters.

Long press SET to enter parameter setting mode.
Short press SET to switch between P0 and P1.
Use the Up (+) or Down (-) buttons to adjust the values within P0 or P1.

P0 Parameters (T1 Timer Time Mode)

P0-0: T1 Timer time mode is seconds.
P0-1: T1 Timer time mode is minutes.
P0-2: T1 Timer time mode is hours.

P1 Parameters (Operation Mode)

P1-0: T1 time delay relay (T1 timer).
P1-1: T1 delay time relay releases (T1 timer).
P1-2: T1 timer, then T2 successor electrical release (T2 timing) ends.
P1-3: T1 delay time relay releases (T1 timer), then T2 successor Electric energized (T2 timing) ends.
P1-4: T1 timer, then T2 successor electrical release (T2 timer), repeat the cycle.
P1-5: T1 delay time relay releases (T1 timer), then T2 successor Electric energized (T2 timer), repeat the cycle.

6.4. Example: 10 Seconds ON, 20 Seconds OFF Loop

If you need the device to turn ON for 10 seconds, then OFF for 20 seconds, and continuously loop:

Set T1 to 10.
Set T2 to 20.
Set P0 to 0 (T1 timing range is seconds).
Set P1 to 5 (Timer mode is the first to work then stop, would always loop).

6.5. Working Status Curves

Diagrams illustrating various working status curves (P2=0, P2=1, P2=2, P2=3, P2=4) showing relay ON/OFF states over time based on T1 and T2 settings. — Figure 13: Working Status Curves for Different P2 Modes

The working status curves (P2 modes) visually represent the relay's behavior based on the programmed T1 and T2 values and the selected P1 operation mode. Refer to these diagrams to understand the timing logic for each mode.

6.6. Important Note on Timing Mode

This product is primarily designed for countdown operations and cannot be set to a continuous 24-hour working mode without specific cycle programming.

7. User Tips

Saving Settings: After adjusting any time parameters (T1, T2) or P0/P1 modes, ensure you either press the SET button to confirm or wait for 6 seconds for the module to automatically save the settings to memory.
Extending Timer Range: If you need to set a timer beyond 99 seconds (e.g., 100 seconds or more), adjust the P0 parameter to minutes (P0-1) or hours (P0-2) as needed. For example, 100 seconds would be 1 minute and 40 seconds, which can be set by adjusting T1/T2 in minutes mode.
Finding Instructions: If you encounter difficulties, additional information and visual guides might be available on online video platforms (e.g., YouTube) by searching for 'T2310 timer relay' or 'microcomputer time controller'.

8. Troubleshooting

Problem	Possible Cause	Solution
Settings are not saved after power cycle.	Settings were not confirmed or saved correctly.	After adjusting T1/T2, press SET to confirm or wait 6 seconds for automatic save.
Timer range is too short (e.g., cannot set beyond 99 seconds).	P0 parameter is set to seconds mode.	Long press SET to enter parameter mode, then adjust P0 to minutes (P0-1) or hours (P0-2) as needed.
Relay does not activate/deactivate as expected.	Incorrect P1 operation mode selected or wiring error.	Verify the P1 parameter setting matches your desired operation. Double-check all wiring connections according to the diagrams.
Device does not power on.	No power supply or incorrect wiring.	Check power connections and ensure the correct voltage (DC12V/24V or AC110-220V) is applied.
Buzzer is not sounding.	Buzzer may be disabled or faulty.	Check if there's a setting to enable/disable the buzzer (if applicable to your model). If not, the buzzer might be faulty.

9. Maintenance

Keep the device clean and free from dust. Use a soft, dry cloth for cleaning.
Avoid using harsh chemicals or abrasive cleaners.
Ensure the device is installed in a dry environment, away from direct sunlight and heat sources.
Regularly check wiring connections for tightness and signs of wear.
