This image displays the AKO AKO-14532 Electronic Regulator. The front panel includes a red 3-digit LED display, two control buttons (labeled 'PRG' and an arrow), and indicators for R1, R2, and AL. The top surface features a label with wiring diagrams and product specifications, including the model number AKO-14532, supply voltage (230V~), frequency (50/60Hz), maximum current (35mA), and IP66 rating.

4. Installation

4.1 Mounting:

• The AKO-14532 is designed for panel mounting.
• Prepare a cut-out in the control panel with dimensions of 71 x 29 mm.
• Insert the regulator into the cut-out and secure it using the provided mounting clips.
• Ensure sufficient space behind the panel for ventilation and easy access to wiring connections.

4.2 Wiring:

• Refer to the wiring diagram located on the device label for precise terminal assignments.
• Connect the 230V AC power supply (Live and Neutral) to the designated power input terminals.
• Connect the 4-20mA input signal from your sensor or transducer to the appropriate input terminals. Observe polarity.
• Connect the relay outputs (R1 and R2) to the controlled devices (e.g., contactors, valves, heaters). Each relay can handle a maximum current of 8A.
• Ensure all connections are firm, properly insulated, and comply with electrical safety standards.

5. Setup and Configuration

5.1 Initial Power-Up:

After completing the installation and wiring, apply power to the regulator. The display will illuminate, typically showing the current measured process value or a default factory setting.

5.2 Parameter Adjustment:

• Press the 'PRG' button to enter the programming menu.
• Use the arrow buttons (up/down) to navigate through the various parameters.
• Press 'PRG' again to select a parameter for editing. Use the arrow buttons to adjust the value.
• Press 'PRG' to confirm the new value and move to the next parameter or exit the editing mode.
• Key parameters typically include input range scaling (e.g., 4-20mA corresponding to specific engineering units), control setpoints, hysteresis, and relay operating modes. Refer to the comprehensive programming guide for detailed parameter descriptions.

6. Operation

6.1 Display Information:

The 3½ digit LED display continuously shows the current process value as measured by the 4-20mA input, scaled according to your configuration. Indicators R1, R2, and AL (Alarm) will illuminate to show the active status of the respective relays and any alarm conditions.

6.2 Control Buttons:

• PRG Button: Used to access and exit the programming menu, and to confirm parameter selections.
• Arrow Buttons: Used for navigating through menu options and modifying parameter values during configuration.

7. Maintenance

• Regularly inspect the device for any visible signs of damage, wear, or loose connections.
• Clean the front panel with a soft, dry cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these may damage the display or casing.
• Ensure the operating environment remains within the specified temperature and humidity ranges to prevent premature failure.
• Periodically verify the accuracy of the 4-20mA input by comparing it with a calibrated reference instrument.

8. Troubleshooting

8.1 No Display / No Power:

• Check the 230V AC power supply connections to ensure they are secure and correctly wired.
• Verify that the power source is active and providing the correct voltage.
• Check for any tripped circuit breakers or blown fuses in the power circuit.

8.2 Incorrect Readings:

• Inspect the 4-20mA input sensor and its wiring for proper connection, polarity, and integrity.
• Verify that the regulator's input range settings are correctly configured to match the sensor's output and the desired engineering units.
• Ensure the sensor itself is calibrated and functioning correctly.

8.3 Relays Not Activating:

• Check the wiring and connections of the relay outputs (R1, R2) to the controlled devices.
• Verify that the control setpoints, hysteresis, and relay operating modes are correctly configured in the programming menu.
• Ensure the process value is within the activation range defined by the setpoints.
• Confirm that the controlled devices are operational and correctly wired to the relay contacts.
