2. Safety Information

• Ensure the power supply voltage matches the specifications of the device.
• Disconnect power before making any wiring connections or disconnections.
• Avoid installing the device in areas with high humidity, extreme temperatures, or corrosive gases.
• If strong interference is present, use shielded wires for input signals and connect the shield to the COM terminal.
• For inductive loads or strong interference, consider adding 250V/220nF safety capacitors in parallel at the 220V AC power input and relay output terminals.

3. Setup

3.1. Mounting

The HB961 counter is designed for panel mounting. Ensure adequate space for ventilation around the device. The overall dimensions are 96mm (W) x 48mm (H) x 82mm (D) for horizontal mounting.

Terminal Layout:

Sensor Connection:

• The counter is factory-configured for NPN type sensors (output low when active).
• If using PNP sensors, a suitable resistor (e.g., 510Ω) must be connected between IN and COM.
• Connect sensor power (5V or 12V) from terminals 8 or 9, and sensor common to COM (terminals 4, 5, or 6).
• Connect sensor signal output to In1 or In2 (terminals 1 or 2).

4. Operating Instructions

4.1. Display and Buttons

Figure 4: Front panel with display and buttons

• 6-Digit LED Display: Shows the current count, parameter values, or error codes.
• SET Button: Enters parameter setting mode.
• Up/Reset Button (▲): Increases parameter values or resets the count.
• Shift/Decrease Button (►): Shifts cursor position during parameter setting or decreases parameter values.
• R/S Button: Not explicitly defined in provided materials, typically used for Run/Stop or Save functions.
• J1/J2 Indicators: Show the status of Relay Output 1 and 2 respectively.

4.2. Parameter Settings

To enter parameter setting mode, press the SET button. The default password is PP0000. Use the Up/Reset and Shift/Decrease buttons to navigate and change values.

Key Parameters:

• J1 Output Mode (J1): Sets the operating mode for Relay Output 1 (Range: 1-11).
• J2 Output Mode (J2): Sets the operating mode for Relay Output 2 (Range: 1-11).
• Magnification (A): Multiplier for input pulses.
• Inverse Magnification (b): Divisor for input pulses.
• Initial Value (C): Starting count value.
• Decimal Point (dot): Sets the decimal point position for display resolution.

Alarm Parameters:

These parameters define the trigger points for the relay outputs. They are automatically generated once the relay output mode (x5) is confirmed.

• J1 (Relay 1 Alarm Value 1): -199999 to 999999 (Default: 20000)
• J1-2 (Relay 1 Alarm Value 2): -199999 to 999999 (Default: 40000)
• J2 (Relay 2 Alarm Value 1): -199999 to 999999 (Default: 20000)
• J2-2 (Relay 2 Alarm Value 2): -199999 to 999999 (Default: 40000)
• J2-t (Relay 2 Delay Value): 0.1 to 99999.9 (Default: 0.1)

4.3. Relay Output Modes (J2 Examples)

The counter offers various relay output modes (1-11) for J1 and J2. Here are some examples for J2:

• Mode 1: J2 relay closes when count reaches J2, counter continues.
• Mode 2: J2 relay opens when count reaches J2, counter continues.
• Mode 3: J2 relay closes at J2, opens at J2-2, counter continues. (If J2=J2-2, no action; if J2>J2-2, action is inverted).
• Mode 4: J2 relay closes at J2, counter stops.
• Mode 6: J2 relay closes at J2, opens at J2-2, counter resets. (If J2=J2-2, no action; if J2>J2-2, action is inverted).
• Mode 7: J2 relay closes at J2, counter continues, J2-t delay then opens, counter resets.
• Mode 11: J2 relay closes at J2, counter continues, J2-t delay then opens.

5. Maintenance

The HB961 Intelligent Raster Counter requires minimal maintenance. To ensure optimal performance and longevity:

• Keep the device clean and free from dust. Use a soft, dry cloth for cleaning the display and casing.
• Do not use abrasive cleaners or solvents, as they may damage the plastic parts or display.
• Ensure proper ventilation to prevent overheating.
• Regularly check wiring connections for tightness and signs of wear.

6. Troubleshooting

If you encounter issues with your HB961 counter, try the following steps:

• No Display/Power: Check the power supply connection (AC 220V terminals 21, 22) and ensure the voltage is within the specified range (AC/DC 85-260V).
• Incorrect Counting:
  • Verify sensor wiring (In1/In2, COM, 5V/12V).
  • Check sensor type compatibility (NPN/PNP) and ensure correct resistor usage for PNP sensors.
  • Inspect sensor for damage or obstruction.
  • Review parameter settings (A, b, C, dot) for correct calculation.
  • Ensure input signal quality; use shielded cables in noisy environments.
• Relay Not Activating:
  • Check relay output wiring (J1/J2 terminals).
  • Verify alarm parameter settings (J1, J1-2, J2, J2-2) and relay output mode.
  • Ensure the load connected to the relay does not exceed its capacity (AC250V/3A).
• Display Flashing/Erratic: This may indicate strong electrical interference. Ensure proper grounding, use shielded cables, and consider adding safety capacitors as mentioned in the safety section.

8. User Tips

• Spindle Speed Readings: While primarily a counter, the HB961 can be adapted for spindle speed (RPM) readings. This typically involves connecting a sensor to count rotations and then integrating with an external timer or calculating RPM based on pulses over a known time interval.
• Accurate Length Measurement: For precise length measurements (e.g., with a measuring wheel), carefully calibrate the A and b parameters based on the wheel's circumference and the number of pulses per revolution from your encoder. Adjust the decimal point (dot) for desired resolution.
• Interference Mitigation: If the counter displays erratic readings, ensure all signal wires are properly shielded and grounded. Separating signal wires from power cables can also reduce interference.
