5. Setup and Installation
5.1 Physical Installation
The T2310 is designed for embedded installation. Ensure you have an opening of 63 mm x 42 mm for proper fitting. The overall product size is 67 mm x 45 mm x 34 mm.
5.2 Wiring Diagram
Refer to the following diagram for correct wiring based on your power supply (DC or AC). Ensure all connections are secure and insulated.
Image 2: Wiring diagram for the T2310 timer. The left side shows DC 12V/24V connections with positive (+) and negative (-) terminals, and load connections. The right side shows AC 110V-220V connections with Live (L) and Neutral (N) terminals, and load connections. Both diagrams illustrate the input power and output to the controlled load.
DC 12V/24V Wiring:
- Connect the positive (+) terminal of your DC power supply to the L/+ terminal on the timer.
- Connect the negative (-) terminal of your DC power supply to the N/- terminal on the timer.
- Connect one side of your load to the ON terminal.
- Connect the other side of your load to the OL terminal.
AC 110V-220V Wiring:
- Connect the Live (L) wire of your AC power supply to the L/+ terminal on the timer.
- Connect the Neutral (N) wire of your AC power supply to the N/- terminal on the timer.
- Connect one side of your load to the ON terminal.
- Connect the other side of your load to the OL terminal.
Important: The operating voltage, input voltage, and output voltage must be the same as the label voltage on the device.
6. Operating Instructions
6.1 Display Overview
Image 3: Front view of the T2310 timer, highlighting the PV (Process Value) and SV (Set Value) LED displays. The 'ON' indicator light is also visible, along with the 'SET' button and arrow buttons for adjustment.
- PV (Process Value): The upper green LED display shows the current countdown or elapsed time.
- SV (Set Value): The lower red LED display shows the set timing parameter.
- ON Indicator: A light indicating when the relay output is active.
6.2 Button Functions
- SET Button: Enters setting mode and confirms selections.
- Up Arrow Button (▲): Increases values or navigates through options.
- Down Arrow Button (▼): Decreases values or navigates through options.
- Exit/Cancel Button (X): Exits setting mode or cancels current operation.
6.3 Setting Timing Parameters
The T2310 supports various timing modes. The unit of time (seconds, minutes, hours) is automatically determined by the set value (0-999). For example, if you set 120, it could be 120 seconds, 120 minutes, or 120 hours depending on the context of the setting.
- Enter Setting Mode: Press and hold the SET button for a few seconds until the display changes to show setting options.
- Navigate Options: Use the Up (▲) and Down (▼) arrow buttons to cycle through different parameters such as "Timer On" (P1), "Timer Off" (P2), "Cycle Mode" (P3), etc.
- Select and Adjust: Press SET to select a parameter. Use Up (▲) and Down (▼) to adjust the value. Press SET again to confirm the value and move to the next digit or parameter.
- Save Settings: After adjusting all desired parameters, press and hold the SET button again to save the settings and exit the setting mode. The device will automatically save the last setting upon power-down.
Key Timing Modes:
- Timer On: Sets the duration for which the relay remains active.
- Timer Shutdown: Sets the duration for which the relay remains inactive.
- Infinite Cycle: Configures the device to continuously alternate between 'on' and 'off' states.
- Quantitative Cycle (1~999 times): Sets the device to perform a specific number of 'on/off' cycles before stopping.
6.4 Program Trigger
The T2310 supports both automatic and manual trigger switches. The factory default is automatic trigger, meaning the timer starts automatically upon power-up or completion of a cycle. Consult the full product manual (link provided in product description) for details on switching to manual trigger mode if required.
6.5 Setting Lock
The device includes a setting lock feature to prevent accidental changes. Refer to the detailed manual for instructions on how to activate and deactivate this lock.
7. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the device. Do not use abrasive cleaners or solvents.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Inspection: Periodically check wiring connections for tightness and signs of wear or damage.
8. Troubleshooting
