Contact: 5A 250VAC.
Note: The specific model H3CR-H8L in this manual is rated for 110/120V 50/60Hz. Always verify the voltage rating on your specific unit before wiring.
5. Operating Instructions
The Omron H3CR-H8L Timer operates as a power-off delay timer.
- Power On: Apply power to the timer. The RyON indicator will illuminate.
- Set Time: Rotate the time setting dial to the desired delay time (e.g., 0-12 seconds).
- Operation: When power is applied, the timer's output contacts will immediately change state. When power is removed, the timer will begin its countdown. After the set delay time has elapsed, the output contacts will revert to their original state.
Ensure the time range is correctly selected if your model supports multiple ranges. This specific model has a range of 0.05s to 12s.
6. Maintenance
The Omron H3CR-H8L Timer requires minimal maintenance.
- Cleaning: Periodically clean the exterior of the timer with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Inspection: Regularly inspect wiring connections for tightness and signs of wear or damage.
- Storage: Store the timer in a dry, dust-free environment when not in use.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Timer does not power on (RyON indicator off) | No power supply; incorrect wiring; faulty unit. | Check power source; verify wiring according to diagram; replace unit if faulty. |
| Timer does not count down or output contacts do not switch | Incorrect time setting; faulty output contacts; incorrect wiring. | Adjust time setting; check load connections; verify wiring; replace unit if faulty. |
| Inaccurate timing | Incorrect time setting; environmental factors (temperature, humidity). | Re-adjust time setting; ensure operating environment is within specified limits. |
