4. Setup and Wiring

Proper wiring is crucial for the correct operation of the digital counter. Refer to the wiring diagram and input mode descriptions below for installation.

4.1 Wiring Diagram

Terminal Connections:

• 1, 2: AC 90-260V Power Input
• 3, 4, 5: OUT1 (Output 1) Relay Contacts (NO, Common, NC)
• 6, 7: OUT2 (Output 2) Relay Contacts
• 8: 24V Auxiliary Power Output
• 9: GND (Ground)
• 10: INB (Input B)
• 11: INA (Input A)
• 12: RST (Reset)

4.2 Input Modes

The counter supports four distinct input modes (A, B, C, D) to accommodate various counting requirements. Ensure your sensor wiring and counter settings match the desired mode.

• Input Mode A (Add): INA is for input counting. INB acts as a controller terminal. Counting occurs on the rising edge of INA when INB is at a low level. When INB is at a high level, INA input is not allowed.
• Input Mode B (Up/Down - Add/Subtract): INA is for input counting. INB acts as a controller terminal. Counting occurs on the rising edge of INA. When INB is at a high level, it's a DOWN counting (subtract). When INB is at a low level, it's an UP counting (add).
• Input Mode C (Up/Down - Add and Subtract): INA is for UP counting terminal. INB is for DOWN counting terminal. Both are input counting terminals.
• Input Mode D (Up/Down - Phase Difference Input used as Encoder): INA is for signal advance INB signal, UP counting active. INB is for signal lagging behind INB signal, DOWN counting active. This mode is typically used with encoders.

The counter is compatible with NPN and PNP sensors. Ensure the sensor type matches the counter's configuration for proper operation. It can be connected with various sensors such as encoders, length counting wheels, proximity switches, photoelectric switches, optical sensors, and laser sensors.

5. Operating Instructions

This section describes the basic operation and key functions of the Mypin FH8-6CRRB Digital Counter.

5.1 Key Functions

• SET Key: Press to enter the parameter setting menu. Press again to cycle through parameters or confirm a setting. Hold to exit the menu.
• ˆ (UP) Key: Increases the value of the currently selected digit or parameter.
• ˇ (DOWN) Key: Decreases the value of the currently selected digit or parameter.
• ˆˆ/RST (Shift/Reset) Key: In setting mode, shifts the cursor to the next digit. In normal operating mode, a short press may reset the counter to zero (depending on configuration).

5.2 Setting Parameters

To set parameters such as counting mode, output mode, preset values, and alarm values:

1. Press the SET key to enter the parameter setting menu. The display will show the first parameter.
2. Use the UP and DOWN keys to adjust the value of the current parameter.
3. Use the ˆˆ/RST key to shift between digits when setting numerical values.
4. Press the SET key to confirm the current parameter and move to the next one.
5. Repeat steps 2-4 until all desired parameters are set.
6. Hold the SET key to save changes and exit the setting menu.

5.3 Output Modes

The counter offers 6 kinds of output modes. These modes determine how the relay outputs (OUT1, OUT2) respond to the counting process and preset values. Refer to the detailed programming guide (usually found in the full user manual) for specific configurations of each output mode, including options for high/low alarm and batching functions.

6. Maintenance

To ensure the longevity and accurate performance of your Mypin FH8-6CRRB Digital Counter, follow these maintenance guidelines:

• Cleaning: Regularly clean the display and casing with a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the plastic.
• Environmental Conditions: Operate the device within the specified environmental temperature (0~50℃) and humidity (35~85%RH) ranges. Avoid exposure to direct sunlight, excessive dust, moisture, or corrosive gases.
• Connections: Periodically check all wiring connections to ensure they are secure and free from corrosion.
• Insulation: Maintain proper insulation resistance (≥10MΩ) and strength (AC 1500V 1min) to prevent electrical hazards.
• Power Supply: Ensure the power supply remains stable and within the specified voltage range (90~265V AC/DC or 12-30V AC/DC).

7. Troubleshooting

If you encounter issues with your digital counter, consider the following common troubleshooting steps:

• No Display/Power:
  • Check the power supply connections (AC 90-260V or DC 12-30V) to ensure they are correctly wired and receiving power.
  • Verify that the power consumption does not exceed 5W.
• Incorrect Counting:
  • Ensure the sensor is correctly wired to INA and INB according to the chosen input mode (A, B, C, or D).
  • Verify that the sensor type (NPN/PNP) is compatible and correctly configured in the counter's settings.
  • Check the input signal characteristics (5V≤H≤30V, 0≤L≤2V, rising edge active) and frequency (0.01~9kHz) to match your sensor output.
  • Confirm the counting speed setting (up to 5000 CPS) is appropriate for your application.
  • Inspect the sensor for damage or misalignment.
• Output Not Activating:
  • Check the preset value (SV) to ensure it is correctly set.
  • Verify the selected output mode is appropriate for the desired control logic.
  • Ensure the relay output connections (OUT1, OUT2) are correctly wired to your external device.
  • Confirm the external device connected to the relay output is functioning correctly.
• Erratic Behavior:
  • Check for electromagnetic interference (EMI) from nearby equipment. Ensure proper shielding and grounding.
  • Verify environmental conditions (temperature, humidity) are within specified limits.

If the problem persists after performing these checks, please contact customer support for further assistance.

8. User Tips

• Sensor Selection: Choose a sensor (e.g., proximity, photoelectric, encoder) that is appropriate for the material, speed, and environment of your counting application. Ensure its output type (NPN/PNP) matches the counter's capabilities.
• Calibration: For length measurement applications, carefully calibrate the ratio range (0.0001-999999) to ensure accurate readings based on your counting wheel or encoder resolution.
• Testing: Before full deployment, perform thorough testing of all counting and output functions to confirm the counter operates as expected in your specific setup.
• Documentation: Keep a record of your counter's settings, especially if multiple units are used or if settings are frequently changed.
