5. ינסטאַלירונג און וויירינג
Proper installation and wiring are crucial for the safe and correct operation of the GRT6-S1 relay. This device is designed for 35mm DIN rail mounting.
5.1 וויירינג דיאַגראַמע

פיגורע 5.1: Basic wiring diagram for the GRT6-S1 relay controlling a lamp. Connect the Line (L) and Neutral (N) to the appropriate terminals (A1 and A2 for power supply). The output contacts (15, 16, 18) are used to control the load.
Exampלאַ: If you control a light, set the ON time to 10 seconds and OFF time to 5 minutes. After power is switched on, the bulb will be ON for 10 seconds and OFF for 5 minutes. This cycle continues until the relay power is cut off.
5.2 קאַנעקשאַן סטעפּס
Follow these steps to connect the GRT6-S1 relay:
- Ensure power is disconnected before wiring.
- Mount the GRT6-S1 onto a 35mm DIN rail.
- Connect the power supply wires (L and N) to terminals A1 and A2 respectively.
- פֿאַרבינדט די לאַסט (למשל, לamp, motor) to the output terminals 15 (common), 16 (normally closed), and 18 (normally open) as required by your application.
- Use a screwdriver to securely tighten all terminal screws.
5.3 Visual Wiring and Function Demonstration
ווידעא 5.1: This video demonstrates the physical connection and basic function testing of the GEYA GRT6-S1 timer relay. It shows how to connect power and a load, and how to set and test different timing modes (A and E modes) with a signal light. It also illustrates the effect of short-circuiting the 'S' terminal for function selection.
6. צייט באַשטעטיקן
The GRT6-S1 allows for precise time setting using its rotary potentiometers. The time scale ranges from 0.1 seconds to 100 days, divided into 10 selectable ranges.

פיגורע 6.1: Diagram illustrating how to set the ON (t1) and OFF (t2) times. Each time is set by selecting a time delay range (e.g., 1s-10s, 1min-10min) and then a percentage within that range (0-100%). For example, 6 minutes can be set by selecting the 1min-10min range and 60%.
צו שטעלן די צייט:
- Identify the two time setting knobs: one for t1 (ON time) and one for t2 (OFF time).
- For each knob, first select the desired time range (e.g., 0.1s-1s, 1s-10s, 0.1min-1min, etc.).
- Then, adjust the percentage dial to fine-tune the time within the selected range.
- The actual time is calculated as: (Selected Time Range) × (Selected Percentage).
7. אָפּעראַציע מאָדעס
The GRT6-S1 supports two primary asymmetric cycle modes, selectable via an external jumper on terminals S-A1.
7.1 מאָדע סעלעקציע

פיגורע 7.1: איבערview of GRT6-S1 and GRT6-S2 models, highlighting LED indications, time range selections, time percentage settings, and delay modes. The GRT6-S1 has 1SPDT output, while GRT6-S2 has 2SPDT output.
The function choice is done by an external jumper of terminals S-A1:
- Cycler beginning with pulse (ON first): This is the default mode when no jumper is connected between S and A1. The relay output will turn ON for the set t1 time, then turn OFF for the set t2 time, and repeat.
- Cycler beginning with pause (OFF first): Connect an external jumper between terminals S and A1. In this mode, the relay output will turn OFF for the set t1 time, then turn ON for the set t2 time, and repeat.

10. טראָובלעשאָאָטינג
If you encounter issues with your GRT6-S1 timer relay, refer to the following common troubleshooting steps:
- Relay Not Powering On:
- קוק די מאַכט צושטעלן וואָלtage to terminals A1 and A2. Ensure it is within the AC/DC 24V-240V range.
- Verify that the power connections are secure.
- אויסגאַנג נישט סוויטשינג:
- Confirm that the load is correctly connected to the output terminals (15, 16, 18).
- Check the load itself to ensure it is functional.
- Verify the time settings (t1 and t2) are correctly configured and the selected time range is appropriate.
- Ensure the function selection (jumper on S-A1) is set for the desired operation mode.
- Observe the LED indicators: Green LED should be ON for power, Red LED should change state according to the timing cycle.
- ומפּינקטלעך צייט:
- Recheck the time range and percentage settings on the potentiometers.
- Ensure the potentiometers are not loose or damaged.
