4. Wiring Diagram and Setup

Proper wiring is crucial for the safe and correct operation of the counter. Refer to the diagram below for connection details. Ensure all power is disconnected before attempting any wiring.

4.1. Terminal Connections:

The FH4-4CRNB model has the following terminal connections:

• Power Input (90-260V AC/DC): Connect your main power supply to the designated terminals.
• Output 1 (OUT1): This model features a Relay output. Terminals are provided for Normally Open (NO) and Common (C) connections. The output is rated for 90-260V.
• Auxiliary Power (24V): A 24V output is available for powering external sensors or other low-power devices.
• Input Signals (INA, INB, GND): These terminals are for connecting input devices such as proximity switches, photoelectric switches, or encoders.
• Reset (RST): Connect an external reset button or signal to this terminal if an external reset is desired.

4.2. Installation Steps:

1. Mounting: Install the counter into a panel cutout of 45mm x 45mm. Secure it using the provided brackets.
2. Power Wiring: Connect the power supply (90-260V AC/DC) to the power input terminals as shown in the wiring diagram.
3. Input Device Wiring: Connect your counting input device (e.g., sensor, encoder) to the INA, INB, and GND terminals. Ensure correct polarity for DC sensors.
4. Output Wiring: If using the relay output, connect your controlled device to the OUT1 NO and C terminals.
5. Auxiliary Power: If your input sensor requires 24V power, connect it to the 24V auxiliary power output.
6. External Reset (Optional): If using an external reset, connect a momentary switch between the RST terminal and GND.
7. Verify Connections: Double-check all wiring for correctness and security before applying power.

Warning: Do not apply power until all wiring is complete and checked. Otherwise, it may result in electrical shock, fire, or malfunction. Do not wire with the power on. Do not turn up the power supply when setting this instrument. This may cause electrical shock, fire, or malfunction. Use this instrument in the scope of its specifications. Otherwise, fire or malfunction may result. The internal relay's service life greatly depends on the current and voltage switched via contacts. Over-stressing the contacts with too much current or switching voltage above the contact rating will greatly shorten the life of the relay.

5. Operating Instructions

The FH4-4CRNB counter is operated via the front panel buttons and displays. The top display (PV) shows the current process value (count/length), and the bottom display (SV) shows the set value or preset.

5.1. Front Panel Controls:

• SET Button: Used to enter parameter setting mode and confirm selections.
• K/RST Button: Used to reset the current count (PV) or to navigate through parameters during setting.
• Up Arrow (▲) Button: Used to increase numerical values or scroll through options.
• Down Arrow (▼) Button: Used to decrease numerical values or scroll through options.

5.2. Basic Operation:

1. Power On: Apply power to the unit. The display will show the current process value (PV) and set value (SV).
2. Setting the Preset Value (SV):
   1. Press the SET button to enter the setting mode. The SV display will start flashing.
   2. Use the Up (▲) and Down (▼) buttons to adjust the desired preset value.
   3. Press the K/RST button to move the cursor to adjust different digits.
   4. Press SET again to confirm the preset value and exit the setting mode.
3. Counting: The counter will begin counting based on the input signals received. The PV display will update accordingly.
4. Resetting the Count: Press the K/RST button briefly to reset the current count (PV) to zero.
5. Output Control: When the PV reaches the SV, the OUT1 relay will activate according to its configured mode (e.g., normal open).

6. Maintenance

To ensure the longevity and accurate performance of your MYPIN FH4-4CRNB counter, follow these maintenance guidelines:

• Cleaning: Regularly clean the front panel and display with a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the plastic housing or display.
• Environmental Conditions: Operate the device within the specified environmental range of -20℃ to 50℃ and 30% to 85% relative humidity. Avoid exposure to excessive dust, moisture, corrosive gases, or strong vibrations.
• Connections: Periodically check all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to intermittent operation or damage.
• Inspection: Inspect the unit for any signs of physical damage, such as cracks in the housing or damaged terminals.
• Power Supply: Ensure the power supply remains stable and within the specified voltage range (90-260V AC/DC).

7. Troubleshooting

If you encounter issues with your MYPIN FH4-4CRNB counter, consider the following troubleshooting steps:

• No Display/Power:
  1. Check the power supply connections to ensure they are secure and correctly wired.
  2. Verify that the power source is providing the correct voltage (90-260V AC/DC).
  3. Ensure the unit is properly seated in its mounting.
• No Counting:
  1. Check the input signal wiring (INA, INB, GND) for correct connections and polarity.
  2. Verify that the input sensor is functioning correctly and generating signals.
  3. Ensure the input signal type and level are compatible with the counter's specifications (H Level: 4V<HC<30V, L Level 0V<L<1V).
  4. Confirm that the counter mode is correctly configured for your application.
• Incorrect Counting:
  1. Check for electrical noise or interference in the input signal lines. Use shielded cables if necessary.
  2. Verify the input sensor's accuracy and ensure it's properly aligned with the objects being counted or measured.
  3. Review the counter's settings to ensure the correct counting parameters (e.g., pulse division, direction) are configured.
• Output Not Activating:
  1. Check the output wiring (OUT1 NO, C) for secure connections.
  2. Verify that the set value (SV) is correctly configured and the process value (PV) has reached or exceeded it.
  3. Ensure the connected load is within the relay's specified current and voltage ratings (250V 3A or 30V 3A resistive load).
  4. Check the output mode settings in the counter's parameters.
• Unit Not Responding to Buttons:
  1. Ensure the unit is not in a locked mode (if applicable, refer to the full manual for advanced settings).
  2. Power cycle the device by turning it off and on again.

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

8. User Tips

• Initial Testing: Before deploying the counter in a critical application, perform thorough testing with known inputs and expected outputs to verify its accuracy and functionality.
• Sensor Selection: Choose input sensors (proximity, photoelectric, encoder) that are appropriate for your specific application's speed, environment, and detection requirements.
• Cable Management: Route input and output cables away from power lines and other sources of electrical noise to prevent interference.
• Parameter Backup: For complex configurations, it is advisable to record your parameter settings in case of accidental reset or power loss (though the device has EEPROM for data saving).
