5. Operating Instructions

The H3DKZ-A2 time relay features adjustable settings for time range and operating mode. The specific adjustment methods may vary slightly between H3DKZ-A2, H3DKZ-A1A, H3DKZ-A2A, and H3DK-A2ET models, but the general principles apply.

1. Time Range Selection: Use the rotary switch or dip switches on the front panel to select the desired time range (e.g., 0.1s-10s, 1s-100s, 0.1m-10m, 1m-100m, 0.1h-10h, 1h-100h).
2. Time Setting: Adjust the fine-tuning knob or potentiometer within the selected time range to set the precise delay duration.
3. Mode Selection: If applicable, select the operating mode (e.g., ON-delay, OFF-delay, Interval, Flicker) using the designated switch or selector. Refer to the product's specific datasheet for detailed mode descriptions.
4. Power On: Once all settings are configured and wiring is verified, apply power to the relay. The relay will begin its timing sequence according to the selected mode and time.

Note: Always consult the markings on your specific relay unit for exact terminal designations and setting procedures.

6. Maintenance

The Mechanivis H3DKZ-A2 Time Relay is designed for long-term, reliable operation with minimal maintenance. However, periodic checks can help ensure optimal performance:

• Inspection: Regularly inspect the relay for any signs of physical damage, discoloration, or loose connections.
• Cleaning: Keep the relay free from dust and debris. Use a soft, dry cloth for cleaning. Do not use solvents or abrasive cleaners.
• Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity ranges.

Always disconnect power before performing any maintenance.

7. Troubleshooting

If the time relay is not functioning as expected, refer to the following common issues and solutions:

If problems persist after attempting these solutions, contact qualified technical support.
