4. Installation

Follow these steps for proper installation of the temperature controller:

1. Mounting: The ESM-1510-N is designed for panel mounting. Cut an opening of the specified dimensions (refer to the product datasheet for exact dimensions) in the control panel.
2. Secure the Controller: Insert the controller into the panel opening and secure it using the provided mounting clamps.
3. Environmental Considerations: Install the controller in an environment free from excessive vibration, high humidity, direct sunlight, and corrosive substances. Ensure adequate ventilation to prevent overheating.

5. Wiring Diagram

Correct wiring is crucial for the safe and proper functioning of the controller. Refer to the detailed wiring diagram provided below. Ensure all connections are secure and comply with local electrical codes.

6. Setup and Parameter Configuration

The controller's parameters can be adjusted to suit specific application requirements. Follow these general steps to access and modify settings:

1. Power On: Apply power to the controller. The display will show the current process value (PV).
2. Access Setpoint: Press the SET button once to view the setpoint (SV). Use the UP and DOWN buttons to adjust the setpoint. Press SET again to confirm and return to PV display.
3. Access Parameter Menu: Press and hold the SET button for several seconds to enter the parameter menu. The display will show the first parameter code.
4. Navigate Parameters: Use the UP and DOWN buttons to scroll through parameter codes.
5. Modify Parameter Value: Press SET to view the value of the selected parameter. Use UP and DOWN to change the value. Press SET to save the new value.
6. Exit Menu: To exit the parameter menu, either scroll to the end of the menu or wait for a timeout, and the controller will automatically return to the normal operating display.

7. Operating Instructions

Once installed and configured, the ESM-1510-N operates automatically to maintain the set temperature. The display continuously shows the current process value (PV).

1. Monitoring Temperature: The large red LED display shows the current temperature measured by the Pt1000 sensor.
2. Setpoint Indication: The green LED next to 'SV' illuminates when the setpoint is being displayed or adjusted.
3. Output Status: The red LED next to the relay symbol indicates the status of the relay output. It illuminates when the relay is active (e.g., heating element is on).
4. Temperature Control: The controller will automatically activate or deactivate the relay output to maintain the temperature around the setpoint, based on the configured hysteresis or proportional band.

8. Maintenance

Regular maintenance ensures the longevity and accuracy of your temperature controller:

• Cleaning: Periodically clean the front panel with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Connection Check: Annually inspect all electrical connections for tightness and signs of corrosion.
• Sensor Inspection: Check the Pt1000 sensor and its wiring for physical damage or degradation. Replace if necessary.
• Recalibration: If accuracy issues are suspected, consider recalibrating the sensor or the controller according to manufacturer guidelines or by a qualified technician.
