- S: Trigger Terminal (Control Input)
- 15: Kontak umum
- 16: Normally Closed (NC) Contact
- 18: Normally Open (NO) Contact
3.2 Diagram Wiring
Refer to the following diagrams for typical wiring configurations. Always consult local electrical codes and standards.
Figure 4: Internal wiring schematics for GRT8-M1 (1 SPDT output) and GRT8-M2 (2 SPDT outputs).
Gambar 5: Kelample wiring diagram for function 'E' (Off Delay with S Break) controlling a lamp. L and N represent Live and Neutral connections. Signal is connected to terminal S.
Kabel Example for E Function:
- The relay is powered up.
- When the trigger 'S' is not connected, the bulb will not light.
- When 'S' and A1 are connected, the bulb will turn on.
- When 'S' is off, the relay delays for the set time, then the bulb will turn off.
- Terminal 15-18 is Normally Open (NO), 15-16 is Normally Closed (NC).
4. Operasi jeung Setélan
The GRT8-M1 features three rotary switches for setting time range, time percentage, and function mode.
Figure 6: Illustration of the three rotary knobs for Time Range, Time Percentage, and Function selection.

- Verify all power connections are secure and correctly wired.
- Check for tripped circuit breakers or blown fuses in the power circuit.
- Output Not Switching (Red LED Off/Incorrect):
- Confirm the selected function (Knob 3) and time range/percentage (Knobs 1 & 2) are appropriate for your application.
- If using a control input (S terminal), ensure the trigger signal is correctly applied and within specifications.
- Verify the load connected to terminals 15, 16, 18 is correctly wired and not exceeding the relay's current rating (16A).
- Check the load itself (e.g., bulb, motor) to ensure it is functional.
- Timing salah:
- Re-check the Time Range (Knob 1) and Time Percentage (Knob 2) settings.
- Ensure the selected function (Knob 3) corresponds to the desired timing behavior.
- Operasi intermittent:
- Inspect all wiring for loose connections or damaged insulation.
- Ensure the operating environment is stable and free from excessive electrical noise or temperature fluctuations.
If the problem persists after performing these checks, contact qualified personnel or the manufacturer for assistance. Do not attempt to repair the device yourself.
