5. Setup and Wiring
Follow these steps to properly set up and wire your QF-C04 Counter Module:
- Power Connection:
Connect your DC 4-40V power supply to the V+ and GND terminals on the module. Ensure correct polarity (V+ for positive, GND for negative).
- Increment Input (+1):
The "+1" terminal is used to increment the counter. Connect a momentary switch or a sensor module output to this terminal. Each time the "+1" input receives a signal (e.g., a pulse from a button press or sensor trigger), the counter will increase by one.
- Clear Input (CLR):
The "CLR" terminal is used to reset the counter to zero. Connect a momentary switch to this terminal. When the "CLR" input is activated, the display will reset to 0000.

Note: Always double-check your wiring connections before applying power to prevent damage to the module or connected devices.
6. Operating Instructions
Operating the QF-C04 Counter Module is straightforward:
- Power On: Once correctly wired, apply DC 4-40V power. The module will display the last saved count (due to its memory function) or 0000 if it's the first use or after a manual clear.
- Incrementing the Count: Activate the "+1" input (e.g., press the connected button or trigger the sensor). The displayed count will increase by one. The counter can count up to 9999.
- Clearing the Count: Activate the "CLR" input (e.g., press the connected button). The displayed count will reset to 0000.
- Memory Function: The module automatically saves the current count. If power is removed and then reapplied, the module will resume counting from the last saved value.
7. Maintenance
The Garosa QF-C04 Counter Module requires minimal maintenance to ensure long-term performance:
- Cleaning: Use a soft, dry cloth to gently wipe the module. Do not use abrasive cleaners or solvents.
- Environment: Keep the module in a clean, dry, and dust-free environment. Avoid exposure to direct sunlight, high humidity, or corrosive substances.
- Inspection: Periodically inspect wiring connections to ensure they are secure and free from damage.
8. Troubleshooting
If you encounter issues with your QF-C04 Counter Module, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank | No power or incorrect power connection. | Check power supply (DC 4-40V) and ensure V+ and GND are correctly wired. |
| Counter does not increment | Faulty "+1" input connection or switch/sensor. | Verify the connection to the "+1" terminal. Test the switch or sensor independently. |
| Counter does not clear | Faulty "CLR" input connection or switch. | Verify the connection to the "CLR" terminal. Test the clear switch independently. |
| Incorrect count | Interference or rapid/bouncing input signals. | Ensure input signals are clean. Consider adding debouncing circuitry if using mechanical switches. |
