Agatige Coolant Level Sensor Instruction Manual

1. Introduction

This manual provides detailed instructions for the installation, operation, and maintenance of the Agatige Coolant Level Sensor. This sensor is designed to detect low liquid levels in water tanks, particularly for generator sets, trucks, vehicles, and marine boats, providing an alarm signal to prevent engine damage due to insufficient coolant.

2. Product Features

• Coolant Level Monitoring: Outputs a switch signal when the water level falls below the probe position, alerting the generator control device.
• Enhanced Safety: Promotes low water level alarm and shutdown functions for stable and safe operation, improving efficiency.
• Reliable Performance: Features a normally closed (NC) operating mode with a wide working voltage range of 5-35V DC.
• Versatile Application: Suitable for equipment and devices requiring water level alarms, compatible with non-corrosive liquids having similar electrical resistivity to water.
• Simple Installation: Designed with an M14 installation thread, lightweight, and compact for quick and convenient setup.

3. Setup and Installation

The Agatige Coolant Level Sensor is designed for straightforward installation. Follow these steps to ensure proper setup:

1. Identify Installation Point: Choose a suitable location in your water tank or coolant reservoir where the sensor probe can accurately detect the desired low-level threshold. The location should have an M14 threaded port.
2. Prepare the Port: Ensure the M14 threaded port is clean and free from debris.
3. Thread the Sensor: Carefully thread the sensor into the M14 port. Do not overtighten.
4. Connect Wiring: Connect the sensor's terminals to your generator control device or alarm system. The sensor operates in Normally Closed (NC) mode, meaning the circuit is closed when the liquid level is above the probe and opens when the level drops below it. Refer to your control device's wiring diagram for specific connections.
5. Secure Connections: Use the provided accessories (spade connectors) to ensure secure and reliable electrical connections.

4. Operating Principle

The Agatige Coolant Level Sensor operates on a simple and effective principle to detect liquid levels. When the liquid (e.g., coolant, water) in the tank is above the sensor's probe, the sensor maintains a closed circuit (Normally Closed - NC). As the liquid level drops and falls below the probe, the sensor detects this change and opens the circuit. This change in circuit state (from closed to open) triggers the connected alarm system or generator control unit, signaling a low liquid level condition.

5. Maintenance

To ensure the longevity and reliable operation of your Agatige Coolant Level Sensor, consider the following maintenance guidelines:

• Regular Inspection: Periodically check the sensor for any signs of physical damage, corrosion, or loose connections.
• Cleanliness: Ensure the sensor probe remains clean and free from buildup (e.g., scale, sludge) that could impede its ability to accurately detect liquid levels. Clean gently with a soft cloth if necessary.
• Wiring Integrity: Verify that all wiring connections are secure and that the insulation is intact to prevent short circuits or signal loss.
• Liquid Compatibility: Confirm that the liquid being monitored is non-corrosive and compatible with the sensor's materials.

6. Troubleshooting

If you encounter issues with your Agatige Coolant Level Sensor, consider the following troubleshooting steps:

• No Alarm/Incorrect Reading:
  • Check wiring connections for looseness or corrosion.
  • Verify the liquid level is indeed below the probe when an alarm is expected.
  • Inspect the sensor probe for excessive buildup or damage that might prevent accurate detection.
  • Ensure the control unit or alarm system connected to the sensor is functioning correctly.
• Constant Alarm:
  • Confirm the liquid level is above the probe. If it is, the sensor might be faulty or stuck in an open state.
  • Check for short circuits in the wiring.
• Intermittent Issues:
  • Inspect for loose wiring connections that may be making intermittent contact.
  • Check for vibrations that might affect sensor stability or wiring.

If problems persist after performing these checks, contact Agatige customer support for further assistance.
