6.2 Schema electrică
Refer to the diagram below for correct wiring connections. Ensure power is disconnected before performing any wiring.
Figure 6.2: Wiring diagram for the DH48J-A series, applicable to DH48J-11A. This diagram shows connections for power source, input signal (CP), reset, and relay contacts.
Conexiuni cheie:
- Sursa de alimentare: Connect the appropriate AC or DC voltage to the designated pins (e.g., pins 2 and 7 for 220VAC, or as indicated on the unit for other voltages).
- Input Signal (CP): Connect your counting signal source (contact, level, or NPN sensor) to the CP input pin (e.g., pin 10).
- Resetați: Connect a momentary switch to the Reset pin (e.g., pin 9) to clear the current count.
- Ieșire releu: The SPDT relay contacts are typically available on pins 1, 3, 4, 5, 6, 8. Refer to the diagram for specific Normally Open (NO) and Normally Closed (NC) configurations.
- +12V / 0V: These pins (e.g., pins 8 and 11) may provide auxiliary power for external sensors if applicable to your model.
Caution: Incorrect wiring can damage the device or lead to unsafe conditions. Always verify connections against the diagram and local electrical codes.
7. Funcționare
7.1 Setting the Count Value and Magnification
The DH48J-11A uses dial switches on the front panel to set the target count value and magnification factor (x1, x10, x100). Adjust these dials to your desired settings. The 4-digit display will show the current count.
- Magnification (x1, x10, x100): This setting determines how many input events are required for the display to increment by one unit. For example, if set to x10, the display will increment by 1 after 10 input signals.
- Interval de numărare: The counter can display values from 1 to 9999. With magnification, the total countable events can reach 999900.
7.2 Moduri de numărare
- Up Counting: The display increments with each detected input signal, based on the set magnification.
- Down Counting: The display decrements with each detected input signal, based on the set magnification.
7.3 Funcția de resetare
To reset the counter to zero, press the 'RESET' button on the front panel or activate the external reset input (pin 9). The reset time is approximately 0.05 seconds.
7.4 Power Reset
Upon power-up, the counter performs a power reset, which takes approximately 1 second before normal operation resumes.
8. Întreținere
The DH48J-11A Digital Counter Relay is designed for reliable operation with minimal maintenance. Follow these guidelines:
- Păstrați dispozitivul curat și ferit de praf și umezeală.
- Asigurați o ventilație adecvată pentru a preveni supraîncălzirea.
- Regularly inspect wiring connections for tightness and signs of wear.
- Avoid exposing the device to strong vibrations or corrosive environments.
9. Depanare
If the counter is not functioning as expected, consider the following common issues:
- Fără afișaj/Fără alimentare: Verificați volumul sursei de alimentaretage and wiring connections. Ensure the correct voltage variant of the counter is being used.
- Not Counting: Verify the input signal source and its connection to the CP pin. Ensure the input signal type (contact, level, NPN sensor) is compatible with the DH48J-11A. Check the minimum counting pulse duration (15ms).
- Incorrect Count: Review the magnification setting on the dial switches. Ensure the input signal is clean and free from noise that could cause false counts.
- Reset Not Working: Check the connection to the reset pin or the functionality of the front panel reset button.
- Ieșirea releului nu se activează: Confirm that the count has reached the set target value. Check the relay output wiring and the load connected to it.
For persistent issues, consult a qualified technician or contact customer support.
