Setup and Installation

Model Selection Guide:

The LC4 series offers various configurations. The LC4-P41NA model indicates specific dimensions, display digits, control output, and power voltage. Refer to the table below for a breakdown of the model codes.

Figure 3: Model code breakdown for the LC series, detailing dimensions, settings, display digits, control output, sub output, and power voltage.

Mounting Dimensions:

The LC4-P41NA has dimensions of 48(W) x 48(H) mm (1.89"D x 1.89"W x 1.89"H). Ensure adequate space for installation and ventilation.

Power Connection:

Connect the device to a power supply of 100-240 V a.c. 50/60Hz. Always ensure the power is off before making any connections to prevent electrical shock or damage to the unit.

Operating Instructions

The LC4-P41NA can function as both a counter and a timer. Operation modes and settings are configured using the front panel buttons.

Basic Operation:

• Power On: Once connected to power, the unit will display the current count or time.
• Mode Selection: Press the MODE key to cycle through different operation modes (e.g., counter, timer, batch).
• Setting Values:
  1. Press the SHIFT key to enter set value change mode. The digit to be changed will flash.
  2. Use the UP and DOWN keys to adjust the value of the flashing digit.
  3. Press SHIFT again to move to the next digit.
  4. Once all digits are set, press MODE to save the setting and exit.
• Resetting: Press the RST key to reset the count value, time value, and output status.

Prescale Setting:

The prescale function allows the input pulses to be scaled to a desired unit. The LC4-P41NA supports a wide prescale range from 0.00001 to 999999. Consult the detailed programming manual (not included here) for specific steps on configuring the prescale value.

Modbus Communication (RS485):

For models equipped with RS485 (Modbus-RTU) communication, the device can be integrated into a larger control system. This allows for remote monitoring and control of the counter/timer functions. Refer to the Modbus communication protocol guide for detailed register maps and communication parameters.

Maintenance

Cleaning:

To maintain optimal performance and readability, periodically clean the unit's display and casing with a soft, dry cloth. Avoid using abrasive cleaners or solvents, as these can damage the plastic and LCD screen.

Environmental Conditions:

Ensure the device operates within the specified ambient temperature and humidity ranges to prevent malfunction and extend its lifespan:

• Ambient Temperature: -10 ~ 55 °C
• Ambient Humidity: 35 ~ 85 % RH (non-condensing)

Avoid installing the unit in locations subject to direct sunlight, excessive dust, corrosive gases, or strong vibrations.

Troubleshooting

If you encounter issues with your LC4-P41NA, review the following common problems and solutions:

• Display is blank:
  • Check power connections and ensure the unit is receiving the correct voltage (100-240 V a.c.).
  • Verify that the power supply is active.
• Incorrect counting or timing:
  • Ensure input signals are within the specified voltage and frequency ranges.
  • Check wiring for input signals for proper connection and integrity.
  • Verify the prescale setting is configured correctly for your application.
  • Confirm the operation mode (counter/timer) is set as intended.
• Output not activating:
  • Check the output wiring for correct connections.
  • Verify the set value (SV) is correctly configured and the count/time has reached the set point.
  • Ensure the output mode is correctly selected.
• Unit not responding to button presses:
  • Check if the LOCK indicator is illuminated, indicating the unit is locked. Unlock it if necessary.
  • Power cycle the unit (turn off and on) to reset.
