5. Setup and Wiring

Proper wiring is essential for the safe and correct operation of the module. Ensure all connections are secure before applying power.

5.1. Common Wiring Diagram (Shared DC Power Supply)

This diagram illustrates how to connect the module and an equipment load when both share a common DC power supply.

Figure 5.1: Wiring diagram showing the module connected to a DC power supply and an equipment load. DC+ and DC- from the power supply connect to the module's VCC and GND terminals, respectively. The trigger input is connected to the IN terminal. The equipment is connected to the relay's COM and NO (Normally Open) terminals, with the other side of the equipment connected to DC+.

5.2. Module Control AC Load Wiring Diagram

This diagram shows how to use the module to control an AC load, such as a 220V device. Note that the module itself is powered by DC 12V, but its relay can switch AC power.

Figure 5.2: Wiring diagram for controlling an AC load. The module is powered by DC 12V (DC+ to VCC, DC- to GND). The trigger input connects to IN. The AC load (e.g., 220V equipment) is connected to the relay's COM and NO terminals, with the AC "Fire Wire" connected to one relay terminal and the "Zero Wire" connected to the other side of the equipment.

6. Operating Instructions and Modes

The module offers 8 distinct operating modes, adjustable from 0.1 seconds to 99 hours. Use the control buttons (SET, ADD, Enter) to configure the desired mode and time parameters.

6.1. Setting Time Unit

To select the T1 time unit, press the ADD button. The display will show a value (0/1/2/3). Press ADD again to cycle between the units:

• 0: Seconds (0.1s - 99.9s)
• 1: Seconds (1s - 999s)
• 2: Minutes (1min - 999min)
• 3: Hours (1h - 99h)

6.2. Selecting Operating Mode

Press and hold the SET button for a long time to enter the function selection menu. The display will show P1-P8. Press the SET button briefly to switch between the 8 functions.

6.3. Detailed Mode Descriptions

Figure 6.1: Visual representation of the 8 operating modes (P-1 to P-8) with their respective descriptions and functionalities.

1. P-1: Delayed Disconnection
   The relay is activated upon power-on. After a delay of T1, the relay disconnects.
2. P-2: Time-Delayed Absorption (Triggered)
   Upon power-on, the time delay T1 starts. After T1, the relay engages. A low-level signal on the IN terminal will re-trigger this function once.
3. P-3: Cyclic On/Off (Power-on Start)
   Upon power-on, the relay engages. After delay T1, the relay disconnects. After delay T2, the relay engages. This cycle repeats. The number of cycles can be adjusted from 1 to 99 or set for an infinite cycle.
4. P-4: Cyclic On-Off (Delay First, Power-on Start)
   Upon power-on, delay T1 starts. After T1, the relay engages. After delay T2, the relay disconnects. This cycle repeats. The number of cycles can be adjusted from 1 to 99 or set for an infinite cycle.
5. P-5: Trigger Delay Absorption (Repeatable)
   The relay is initially inactive. After a trigger signal, the relay activates. After delay T1, the relay disconnects. A low-level signal on the IN terminal will re-trigger this function. The cycle times can be adjusted from 1 to 99 or set for an infinite cycle.
6. P-6: Trigger Time-Delay Disconnect
   The relay is initially inactive. Upon triggering, the relay engages. After delay T1, the relay disconnects. A low-level signal on the IN terminal will re-trigger this function once.
7. P-7: Trigger Cycle On-Off (Repeatable)
   The relay is initially inactive. Upon triggering, the relay engages. After delay T1, it disconnects. After delay T2, it engages. This cycle repeats. The number of cycles can be adjusted from 1 to 99 or set for an infinite cycle.
8. P-8: Trigger Cycle On/Off (Delayed Start)
   The relay is initially inactive. Upon triggering, delay T1 starts. After T1, the relay engages. After delay T2, the relay disconnects. This cycle repeats. The number of cycles can be adjusted from 1 to 99 or set for an infinite cycle.

7. Maintenance

The GODIYMODULES Time Delay Relay is designed for reliable operation with minimal maintenance. To ensure longevity and proper function:

• Keep the module clean and free from dust and moisture.
• Avoid exposing the module to extreme temperatures or direct sunlight.
• Periodically check all wiring connections to ensure they remain secure.
• Do not attempt to open or modify the module, as this may void any warranty and could lead to malfunction.

8. Troubleshooting

If you encounter issues with your time delay relay module, consider the following common troubleshooting steps:

• Module Not Powering On: Verify that the DC 12V power supply is correctly connected to the VCC and GND terminals and is providing the correct voltage. Check for loose connections or damaged wires.
• Relay Not Activating/Deactivating:
  • Ensure the correct operating mode (P-1 to P-8) is selected.
  • Check the set time (T1, T2) and time unit.
  • If using a trigger, verify the trigger signal is being applied correctly to the IN terminal.
  • Confirm the load is correctly wired to the relay's COM, NO, or NC terminals.
• Incorrect Timing: Double-check the set time values and the selected time unit (seconds, minutes, hours).
• Display Issues: If the digital display is blank or showing erratic characters, check the power supply and connections.
