5. Setup and Installation

Proper installation is crucial for the accurate and safe operation of the liquid level controller. Please follow these guidelines carefully.

5.1 Safety Precautions

• Ensure the power supply is disconnected before performing any wiring or installation.
• All wiring should be performed by qualified personnel in accordance with local electrical codes.
• Verify the power supply voltage matches the device's requirements (AC 220V 50HZ).

5.2 Mounting

The controller is designed for panel mounting. Refer to the dimensional drawing for precise cutout and mounting hole requirements.

This technical drawing provides the physical dimensions of the controller and illustrates the layout of the rear wiring terminals, crucial for installation planning.

5.3 Wiring Instructions

Connect the pressure sensor and power supply to the rear terminal block as per the diagrams below. Ensure all connections are secure to prevent intermittent operation or damage.

This diagram illustrates the two primary wiring configurations: a two-wire current output (4-20mA) connection and a three-wire voltage output (0-5V/10V) connection, showing how to connect the pressure sensor to the meter.

• Two-Wire Current Output (4-20mA) Sensor:
  • Connect the sensor's Positive (1 pin) to the 24V DC power supply.
  • Connect the sensor's Signal (2 pin) 4-20mA output to the meter's current input.
  • Red wire: 24V DC. Black wire: current output.
• Three-Wire Voltage Output (0-5V/10V) Sensor:
  • Connect the sensor's Positive (1 pin) to the 24V DC power supply.
  • Connect the sensor's Signal (2 pin) 0-5V/10V output to the meter's voltage input.
  • Connect the sensor's Public (3 pin) to the meter's common ground.
  • Red wire: 24V DC. Yellow wire: power supply-. Black wire: voltage output+.

Ensure the correct input type (current or voltage) is selected in the controller's settings to match your sensor.

6. Operation

Once installed and wired, the controller is ready for operation. The front panel provides visual feedback and control options.

6.1 Power On

After connecting the AC 220V 50HZ power supply, the controller will power on and initiate its self-test sequence. The digital display (PV) will show the measured value, and the bar graph will indicate the level.

6.2 Reading the Display

• PV Display: Shows the current measured value numerically.
• Measuring Bar Display: Provides a visual representation of the measured level, typically ranging from 0 to 100.
• Indicator Lights: Illuminate to signal specific alarm conditions (AHH, AH, AL, ALL) based on configured setpoints.

6.3 Setting Parameters

To configure alarm setpoints, input types, or other operational parameters, use the front panel buttons:

This image provides a close-up of the SET, Add, Reduce, and Displacement buttons on the front panel, showing their design and labels.

1. Press the SET button to enter the parameter setting mode. The display will change to show the first configurable parameter.
2. Use the Add (▲) and Reduce (▼) keys to adjust the value of the currently displayed parameter.
3. Use the Displacement (◄) key to move between digits within a parameter value or to navigate to the next parameter.
4. Press SET again to save the changes and move to the next parameter, or to exit the setting mode if all parameters have been configured.

Refer to the detailed programming guide (if available separately) for specific parameter codes and their functions.

7. Maintenance

The Acogedor HWP-T804-01-23-HL-P controller is designed for low maintenance. Regular checks can help ensure its longevity and accurate performance.

7.1 Cleaning

• Periodically wipe the front panel with a soft, dry cloth to remove dust and grime.
• Do not use abrasive cleaners or solvents, as these can damage the display or housing.
