Control Buttons:

• STOP: Stops or starts the timer function.
• SET: Enters/exits programming mode and selects parameters.
• UP (+): Increases numerical values or navigates options.
• DOWN (-): Decreases numerical values or navigates options.

Terminals:

• VIN / GND: Power input terminals (DC 5V-36V).
• OUT+ / OUT- / GND: Load output terminals (DC 5V-36V).
• SIGN / GND T: Trigger signal input terminals (DC 3V-24V).

5. Setup and Wiring

Proper wiring is crucial for the safe and correct operation of the module. Refer to the wiring diagram below for connections.

Figure 3: Detailed wiring diagram and button function overview for the HW-0516 module.

Wiring Steps:

1. Power Input: Connect your DC 5V-36V power supply to the VIN (positive) and GND (negative) terminals on the right side of the module. Ensure correct polarity.
2. Load Connection: Connect your DC load (e.g., motor, LED strip) to the OUT+ (positive) and OUT- (negative) terminals. The output voltage will be the same as the input voltage.
3. Trigger Signal: If using an external trigger, connect the positive trigger signal (DC 3V-24V) to the SIGN terminal and the negative/ground of the trigger source to the GND T terminal on the left side. Note that the trigger signal ground and system ground are isolated to improve anti-jamming capability, but can be connected to a common ground if desired.
4. Initial Power-Up: After wiring, apply power. The LED display should light up, indicating the current operating mode or a default setting.

Caution: Always ensure power is disconnected before making or changing any wiring connections to prevent damage to the module or connected devices.

6. Operating Instructions

The module operates in various modes, each with specific timing logic. Programming involves selecting a mode and setting time parameters.

6.1. Display Modes and Time Units

• In normal operation, the display shows the current time value.
• Time Unit Selection: In parameter setting mode, a short press of the SET button cycles through time units:
• XXX. (decimal point in the hundred's place): 0.1 seconds to 99.9 seconds
• XX.X (decimal point in the ten's place): 1 second to 999 seconds
• X.X.X (no decimal point): 1 minute to 999 minutes

6.2. Entering and Exiting Programming Mode

1. Enter Programming Mode: Long press the SET button for approximately 3 seconds. The display will show the current operating mode (e.g., P1.1).
2. Select Operating Mode: Use the UP and DOWN buttons to cycle through the available operating modes (P1.1 to P4).
3. Enter Parameter Setting: Once the desired mode is displayed, short press the SET button to enter parameter setting for that mode. The display will flash, indicating the parameter can be adjusted.
4. Adjust Parameters: Use the UP and DOWN buttons to change the time value. Short press SET to change the time unit (seconds, 0.1 seconds, minutes).
5. Save and Exit: After setting all parameters for the chosen mode, long press the SET button for approximately 3 seconds to save the settings and exit programming mode. The module will return to its normal operating state.

6.3. Operating Modes (P1-P4)

The module supports four main operating modes, each with distinct timing logic:

• P1: Delay OFF (Trigger ON, Delay OFF)
  When a trigger signal is received, the relay turns ON. After a set delay time (OP), the relay turns OFF. If the trigger signal is removed during the delay, the timer resets.
• P2: Delay ON (Trigger ON, Delay ON, then OFF)
  When a trigger signal is received, the relay remains OFF for a set delay time (OP), then turns ON. After another set delay time (CL), the relay turns OFF. If the trigger signal is removed during the delay, the timer resets.
• P3: Cycle ON-OFF (Trigger ON, Cycle Starts, then OFF)
  When a trigger signal is received, the relay turns ON for a set time (OP), then OFF for a set time (CL). This cycle repeats for a specified number of times (LOP). After all cycles are complete, the relay turns OFF. If the trigger signal is removed during the cycle, the timer resets.
• P4: Signal Holding Relay ON (Trigger ON, Relay ON, Trigger OFF, Relay OFF after Delay)
  When a trigger signal is received, the relay turns ON. The relay remains ON as long as the trigger signal is present. When the trigger signal is removed, the relay remains ON for a set delay time (OP), then turns OFF. If the trigger signal is re-applied during the delay, the timer resets and the relay stays ON.

6.4. STOP Button Functionality

• A short press of the STOP button in normal operating mode will toggle the relay output ON or OFF.
• When the relay is OFF (indicated by 'OFF' on the display), the module is in a low-power state.
• Pressing STOP again will reactivate the module and resume its programmed function.

7. Maintenance

To ensure the longevity and reliable performance of your Fafeicy HW-0516 module, follow these maintenance guidelines:

• Cleaning: Keep the module free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using liquids or abrasive cleaners.
• Environment: Operate the module within its specified working temperature range (-40℃ to 85℃). Avoid exposure to extreme humidity, direct sunlight, or corrosive environments.
• Connections: Periodically check all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to intermittent operation or damage.
• Heat Dissipation: If operating at higher currents (above 15A), ensure adequate heat dissipation is provided, such as a heatsink or proper ventilation, to prevent overheating.
