Terminal Connections:
- Terminals 1 & 2 (NC, NO): Relay Output 1 (Normally Closed, Normally Open)
- Terminals 3 & 4 (NC, NO): Relay Output 2 (Normally Closed, Normally Open)
- Terminals 5 & 6 (NC, NO): Relay Output 3 (Normally Closed, Normally Open)
- Terminals 7 & 8 (NC, NO): Relay Output 4 (Normally Closed, Normally Open)
- Terminals 9 & 10 (90-260V): AC/DC Power Input (90-260V)
- Terminal 11 (RST): Reset Input
- Terminal 12 (24V): 24V DC Auxiliary Power Output (for sensors, etc.)
- Terminal INA: Input A (for counting signal)
- Terminal INB: Input B (for counting signal, direction, or phase)
- Terminal GND: Ground for inputs
Note: The specific function of INA and INB may vary based on the selected counting mode (e.g., single input, quadrature input). Refer to the device's on-screen menu for mode configuration.
7. Operation
After successful wiring and power-up, the counter will display the current count. The front panel typically includes buttons for setting parameters and controlling the count.
Basic Functions:
- Counting: The device counts pulses received on the input terminals (INA/INB).
- Preset Setting: Use the front panel buttons to navigate menus and set up to 4 preset values. When the count reaches a preset value, the corresponding relay output will activate.
- Reset: The count can be reset manually via a front panel button or externally via the RST input terminal.
- Mode Selection: The counter supports various counting modes (e.g., up/down counting, batch counting, frequency measurement). These modes are typically configured through the device's internal menu system.
Detailed instructions for menu navigation and parameter setting are usually provided in the device's on-screen interface or a separate programming guide.
8. Maintenance
The MYPIN FH4-4CRNB Digital Counter requires minimal maintenance. Follow these guidelines to ensure longevity:
- Cleaning: Gently wipe the display and casing with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Inspection: Periodically check wiring connections for tightness and signs of wear or corrosion.
- Environment: Ensure the operating environment remains within specified temperature and humidity ranges.
9. Troubleshooting
If you encounter issues with your digital counter, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | No power supply or incorrect voltage. | Check power connections and ensure voltage is within 90-260V AC/DC. |
| Counter not counting. | Incorrect input wiring, faulty sensor, or incorrect counting mode. | Verify input wiring (INA, INB, GND). Test the sensor. Check counting mode settings in the menu. |
| Relay output not activating. | Preset value not reached, incorrect output wiring, or faulty relay. | Confirm the count has reached the preset. Check relay output wiring. Test the relay if possible. |
| Display shows error code. | Internal error or parameter setting issue. | Refer to the device's specific error code list (if available) or try resetting the device to factory defaults. |
