Proper installation of the 528T unit requires a basic understanding of automotive electrical systems. Refer to your vehicle's wiring diagrams as needed.

Wiring Diagram and Connections

The 528T unit features several color-coded wires. Identify each wire's function before making connections.

• Okun Pupa: 12V Constant Power Input. Connect this to a fused 12V constant power source.
• Waya Dudu: Ground Input. Connect this to a reliable chassis ground.
• Black/White Stripe Wire: Trigger Input (Negative). This wire is used for negative pulse or state change triggers.
• Okun Yellow: Trigger Input (Positive). This wire is used for positive pulse or state change triggers.
• Okun Osan: Relay Output (Normally Open - NO). This terminal connects to the device you want to power after the delay.
• Waya Brown: Relay Output (Normally Closed - NC). This terminal connects to the device you want to power until the delay activates.
• Blue Wire Loop: Trigger Selection.

Trigger Type Selection

The 528T can be configured for either positive or negative triggering using the blue wire loop.

• For Negative (Ground) Trigger: Leave the blue wire loop mule. The unit will trigger when the Black/White wire receives a negative pulse or goes to ground.
• For Positive (12V) Trigger: Ge the blue wire loop. The unit will trigger when the Yellow wire receives a positive pulse or 12V.

1. Awọn isopọ Agbara: Sopọ awọn Pupa wire to a fused 12V constant power source and the Dudu wire to a solid chassis ground.
2. Isopọ ti o nfa: Based on your desired trigger type, connect either the Dudu/funfun wire (for negative trigger, blue loop intact) or the Yellow wire (for positive trigger, blue loop cut) to your trigger source. The unused trigger wire should be insulated.
3. Asopọmọra fifuye: Connect the device you wish to control to the appropriate relay output wire.
   • Lo awọn ọsan wire for a Normally Open (NO) connection. This means the circuit is open (off) until the timer activates, then it closes (on) for the set duration.
   • Lo awọn Brown wire for a Normally Closed (NC) connection. This means the circuit is closed (on) until the timer activates, then it opens (off) for the set duration.
4. Idabobo: Ensure all connections are properly soldered or crimped and insulated with electrical tape or heat shrink tubing.
5. Iṣagbesori: Mount the 528T unit in a dry, secure location away from excessive heat or vibration.

Adjusting the Timer Delay

The 528T features an adjustable potentiometer (a small dial or screw) on the unit's circuit board. This allows you to set the delay time from approximately 0 to 60 seconds.

• Use a small screwdriver to carefully turn the potentiometer.
• Turning clockwise typically increases the delay time.
• Turning counter-clockwise typically decreases the delay time.
• Test the delay after each adjustment to ensure it meets your requirements.

Ṣiṣẹ Aago

Once installed and configured, the timer activates upon receiving the specified trigger signal (positive or negative, depending on the blue loop setting).

• When triggered, the internal relay will switch its state (NO to closed, NC to open) for the duration set by the potentiometer.
• The timer will re-initiate if a new trigger signal is received while it is already timing, or if the trigger state changes.

Itoju

• Ayẹwo igbagbogbo: Periodically check all wiring connections for looseness or corrosion.
• Idaabobo Ayika: Ensure the unit remains protected from water, dust, and extreme temperatures. If installed in an exposed area, consider adding a protective enclosure.
• Ninu: If necessary, gently clean the exterior of the unit with a dry, soft cloth. Do not use harsh chemicals or solvents.

Unit Does Not Activate

• Ṣayẹwo Agbara: Verify that the Red wire has a constant 12V supply and the Black wire has a solid ground connection.
• Check Trigger: Ensure the correct trigger wire (Black/White for negative, Yellow for positive) is connected and receiving the appropriate signal. Confirm the blue loop is correctly configured for your trigger type.
• Ṣe àyẹ̀wò ìrùsókè: Ensure the device connected to the Orange or Brown wire is functioning correctly and its wiring is secure.

Incorrect Delay Time

• Ṣe àtúnṣe Potentiometer: Carefully adjust the potentiometer on the unit. It may require fine-tuning.
• Test Repeatedly: Some units may exhibit slight variations in timing with rapid, repeated triggers. Test the delay under typical operating conditions.

Relay Not Switching

• Check Load Current: Ensure the connected load does not exceed the 30A rating of the internal relay. Overloading can damage the relay. Consider using an external relay for higher current applications.
• Aṣiṣe inu: If all other checks pass, the internal relay or circuit may be faulty.
