2. Setup uye Kuiswa
Proper installation is crucial for the optimal performance and longevity of your DHC-96 device. Ensure all power sources are disconnected before proceeding with installation.
2.1 Panel Mounting
- Prepare a panel cutout with dimensions of 96 x 49 mm.
- Insert the DHC-96 unit into the cutout from the front.
- Secure the unit using the provided mounting clips or brackets from the rear of the panel. Ensure a snug fit to maintain the IP 54 frontal protection rating.
2.2 Simba reKugovera Connection
The DHC-96 supports a universal power supply. Connect the power source to the designated terminals on the rear of the unit.
- For AC/DC power, connect to 80-270 Vca/cc terminals.
- For DC power, connect to 16-36 VCC terminals.
- Ensure correct polarity for DC connections.
2.3 Measurement Input Connection
Connect the signal source to the programmable measurement input terminals. Refer to the wiring diagram provided with your specific model for detailed connection points.
- Zve voltage measurements, connect the voltage source.
- For current measurements, connect through a shunt or current transformer as appropriate for your application.
- Ensure galvanic insulation between external circuits is maintained.
2.4 Relay Output Connection
The DHC-96 features two output relays for control and alarm functions. Connect these relays to your external control systems or alarm indicators as required.
- Identify the relay output terminals.
- Wire the relays according to your application's control logic.
- Configure alarm delays and interlocking settings via the device's menu.
3. Operating Instructions
Once installed and powered, the DHC-96 is ready for operation. The front panel features a digital display and control buttons for configuration and monitoring.
3.1 Ratidza Pamusoroview
The digital display shows the measured electrical variant (e.g., voltage, current, frequency) or the proportional value of a process signal. The unit automatically adjusts the display based on the configured measurement type.
- DC Systems: Capable of measuring voltage, current, frequency, and other industrial process variables.
- AC Models: Perform measurements in True Effective Value (TRMS).
- Decimal Point: The decimal point is self-configurable to suit your measurement precision requirements.
3.2 Bhatani Mabasa
The front panel buttons allow for navigation through menus, parameter configuration, and display adjustments. Specific button functions may vary slightly depending on the firmware version.
- Miseve Yekuruboshwe/Kurudyi (< / >): Typically used for navigating through menu options or adjusting values.
- Miseve Yekumusoro/Yakadzika (∧ / ∨): Used for increasing/decreasing values or selecting options.
- Bhatani reMenu/Enter: Used to access the main menu, confirm selections, or save settings.
- Escape/Back Button: Used to exit a menu or cancel an operation.
3.3 Configuration and Programming
The DHC-96 allows for programming various parameters to suit specific application needs. This includes setting the measurement input type, configuring alarm thresholds, and defining relay behaviors.
- Access the configuration menu by pressing the Menu/Enter button.
- Navigate mukati memenu sarudzo uchishandisa mabhatani emiseve.
- Select the desired parameter to modify and adjust its value.
- Save changes before exiting the menu.
- Refer to the detailed programming guide (if available separately) for advanced configurations.
4. Kuchengeta
The DHC-96 is designed for reliable operation with minimal maintenance. Regular inspection and cleaning will help ensure its continued performance.
- Kuchenesa: Nguva nenguva chenesa jira repamberi nekanyoro, damp cloth. Do not use abrasive cleaners or solvents, as they may damage the display or casing.
- Kuongorora: Regularly inspect the wiring connections for any signs of wear, corrosion, or looseness. Ensure the unit is securely mounted in its panel cutout.
- Environment: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent damage. The IP 54 frontal protection helps against dust and splashing water, but the unit is not designed for immersion.
- Hapana Zvikamu Zvinoshandiswa Nemushandisi: The DHC-96 contains no user-serviceable parts. Do not attempt to open the casing, as this will void the warranty and may expose you to electrical hazards.
5. Kugadzirisa matambudziko
If you encounter issues with your DHC-96, refer to the following common troubleshooting steps. For problems not listed here, contact Circutor technical support.
- Hapana Chiratidziro/Simba:
- Check the power supply connections to ensure they are secure and correctly wired.
- Iva nechokwadi chekuti simba remagetsi rinobudatage is within the specified range (80-270 Vca/cc or 16-36 VCC).
