KUS EL0274 Waterproof Water Temperature Gauge Instruction Manual

Introduction

This manual provides comprehensive instructions for the KUS EL0274 Waterproof Water Temperature Gauge. It is designed to display the temperature of a water tank when connected to compatible water temperature sensors. The gauge utilizes a moving-magnet principle for accurate and stable readings, featuring good endurance and anti-vibration capabilities.

Key features include:

• Indicating Range: 40-120℃ (104-248°F)
• Working Voltage: 12V/24V (a resistor is included for 24V applications)
• Backlight Options: Red or Yellow
• Protection Grade: IP67 (completely waterproof, anti-fogging function, works up to 1m underwater)
• Material: 316 Stainless steel bezel with curved glass
• Fixing Dimension: 52mm (2 inches)

Package Contents

Verify that all items are present in the package:

• 1x Water Temperature Gauge
• 1x Multi-plug Socket (Connector Cable)
• 1x Installation Instruction Sheet
• 1x Resistor (for 24V applications)

Installation Instructions

Follow these steps for proper installation of the water temperature gauge:

1. Prepare Mounting Hole: Cut a 52mm (2-1/16") diameter hole in the dashboard or desired mounting panel. Ensure a minimum clearance of 55mm (2-3/16") behind the panel for the gauge body.
2. Align Gauge: Remove the fixing ring. There is an alignment tab on the gauge body; place the gauge in the panel hole and mark the position of this tab to correctly align the gauge.
3. Secure Gauge: Insert the gauge through the panel from the front, fit and tighten the fixing ring from the rear.
4. Wiring Connections: Connect the wires according to the wiring diagram provided. Note that a resistor is required for 24V circuit operation.
5. Backlight Selection: Choose between red and yellow backlight by connecting the corresponding wire (Orange for Red, Yellow for Yellow) into port IV at the back of the gauge.
6. Voltmeter Note: If the gauge is a voltmeter, there are no black wire or resistors in the kit. This instruction applies specifically to the water temperature gauge.

Wiring Diagram and Connection Details

Refer to the following connection details for the multi-plug socket:

• Red Wire: +12V/24V (Power Supply)
• Orange Wire: Red Backlight (+)
• Yellow Wire: Yellow Backlight (+)
• Blue Wire: Ground (-)
• Black Wire: Sensor Signal

Operating Instructions

Once properly installed and wired, the KUS Water Temperature Gauge will display the water temperature within its specified range of 40-120℃.

• Power On: The gauge activates when power is supplied to the red wire (+12V/24V) and the blue wire is grounded.
• Temperature Display: The needle will indicate the current water temperature as measured by the connected sensor.
• Backlight Operation: The chosen backlight (red or yellow) will illuminate when its respective wire (orange for red, yellow for yellow) receives power.

Maintenance

The KUS Water Temperature Gauge is designed for durability and requires minimal maintenance. Due to its IP67 waterproof and anti-fogging features, it is built to withstand harsh environments.

• Cleaning: Clean the gauge face with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the glass or bezel.
• Inspection: Periodically check wiring connections for corrosion or looseness, especially in marine or high-vibration applications.
• Sensor Check: Ensure the water temperature sensor is clean and properly installed for accurate readings.

Troubleshooting

If you encounter issues with your KUS Water Temperature Gauge, consider the following:

• No Power/No Display:
  • Check the power supply to the red wire (+12V/24V).
  • Verify the ground connection (blue wire).
  • Ensure all connections are secure and free from corrosion.
• Incorrect Temperature Reading:
  • Confirm the water temperature sensor is correctly installed and functioning.
  • Check the black sensor signal wire for proper connection.
  • Ensure the gauge is compatible with your specific water temperature sensor.
• Backlight Not Working:
  • Verify power to the orange (red backlight) or yellow (yellow backlight) wire.
  • Ensure the correct backlight wire is connected to port IV.
• Gauge Fogging: While the gauge has anti-fogging properties, extreme temperature changes or prolonged exposure to high humidity might temporarily affect visibility. This should clear up under normal operating conditions.

If problems persist, consult a qualified technician or contact KUS customer support.
