LAE AT1-5BS6E-AG Electronic Heating/Cooling Controller User Manual

1. Introduction

This manual provides essential information for the proper installation, operation, and maintenance of the LAE AT1-5BS6E-AG Electronic Heating/Cooling Controller. This device is designed for precise temperature management in various industrial and commercial applications, utilizing NTC/PTC inputs and controlling external systems via relay outputs.

Please read this manual thoroughly before installation and use to ensure safe and efficient operation of the controller.

2. Safety Information

• Installation and maintenance should only be performed by qualified personnel.
• Disconnect power before performing any wiring or maintenance procedures.
• Ensure the power supply voltage matches the controller's specifications (AC 230V~±10% 50/60Hz).
• Do not exceed the maximum current ratings for the relay outputs (Relay 1: NO-16A(8), Relay 2: NO-7A(2)).
• Protect the controller from moisture, dust, and extreme temperatures outside its operating range.
• Verify all connections are secure to prevent electrical hazards.

3. Product Overview

The LAE AT1-5BS6E-AG controller features a compact design for panel mounting, equipped with a digital display and intuitive control buttons for easy configuration and monitoring.

Figure 1: LAE Electronic Controller
This image displays the LAE electronic controller. It features a black casing with a digital LED display on the front panel. Below the display are several control buttons, including an 'i' button, arrow keys, 'M' button, 'X' button, and a power button. The top surface shows a wiring diagram and model information, including 'Mod. AT2-5BS4E-AG' (note: the product data specifies AT1-5BS6E-AG, this image serves as a general visual reference for the controller type), 'T1.T2 -50~120°C', and relay specifications. The device is designed for panel mounting.

Front Panel Components:

• Digital Display: Shows current temperature, setpoints, and operational status.
• Control Buttons: Used for navigation, parameter adjustment, and function activation. (e.g., 'i' for information, arrow keys for value adjustment, 'M' for menu, 'X' for exit/cancel, power button for on/off).
• Indicator Lights: May indicate relay status (e.g., heating/cooling active), alarm conditions, or defrost cycles.

Rear Terminal Block:

The rear of the controller features screw terminals for electrical connections, including power supply, sensor inputs, and relay outputs. Refer to the wiring diagram on the unit or in this manual for specific terminal assignments.

4. Setup and Installation

4.1 Mounting

• The LAE AT1-5BS6E-AG controller is designed for surface mounting.
• Prepare an opening of 71 x 29 mm in the panel where the controller will be installed.
• Insert the controller into the opening and secure it using the provided mounting clips or screws.
• Ensure adequate ventilation around the controller to prevent overheating.

4.2 Wiring

All electrical connections are made via screw terminals on the rear of the unit. Refer to the wiring diagram printed on the controller or the specific diagram provided with your unit for precise connections.

• Power Supply: Connect the AC 230V~±10% 50/60Hz power supply to the designated L (Line) and N (Neutral) terminals.
• Sensor Inputs:
  • Input 1: Connect the NTC/PTC temperature sensor to the specified terminals.
  • Input 2: Connect the NTC temperature sensor to the specified terminals.
• Relay Outputs: Connect the controlled devices (e.g., compressor, heater, fan) to the Normally Open (NO) contacts of Relay 1 and Relay 2.
  • Relay 1: NO-16A(8)
  • Relay 2: NO-7A(2)
• Ensure all wiring is correctly sized for the current load and properly insulated.

5. Operating Instructions

5.1 Power On/Off

Press and hold the power button (typically marked with a circle and vertical line symbol) to turn the controller on or off.

5.2 Display Information

The digital display typically shows the current temperature measured by the primary sensor. Indicator lights may illuminate to show the status of relays (e.g., heating active, cooling active) or other functions.

5.3 Setting Parameters

To access and modify parameters such as setpoint temperature, differential, operating mode (heating/cooling), and alarm thresholds:

1. Press the 'M' (Menu) button to enter the parameter menu.
2. Use the arrow keys (up/down) to navigate through the parameter list.
3. Press the 'i' or 'M' button again to select a parameter.
4. Use the arrow keys to adjust the parameter value.
5. Press 'M' or 'i' to confirm the new value.
6. Press 'X' (Exit) to return to the main display or exit the menu.

Specific parameter codes and their functions are detailed in the full technical manual provided with the product. Common parameters include:

• Setpoint (SP): Desired temperature.
• Differential (HY): Hysteresis value to prevent rapid cycling of the controlled device.
• Operating Mode (C/H): Selects between Cooling or Heating control.
• Alarm Thresholds: High and low temperature limits for alarm activation.

6. Maintenance

6.1 Cleaning

• Before cleaning, ensure the controller is powered off and disconnected from the main supply.
• Wipe the front panel with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Ensure no liquid enters the controller casing.

6.2 Inspection

• Periodically inspect wiring connections for tightness and signs of wear or damage.
• Check sensors for physical damage or corrosion.
• Ensure the controller's ventilation openings are clear of obstructions.
