Side Mount Float Level Switch User Manual

Model: Side Mount Float Level Switch

Brand: CERTEON

1. Product Overview

The CERTEON Side Mount Float Level Switch is a robust and reliable device designed for point-level detection of liquids in tanks and containers. It operates based on a magnetic reed switch mechanism integrated inside the float assembly. As the liquid level rises or falls, the float moves accordingly, triggering the internal reed contact to open or close the circuit.

Constructed from high-quality polypropylene (PP), this float switch offers excellent chemical resistance, making it suitable for a wide range of applications including water treatment, industrial process control, and general liquid level monitoring.

3. Setup and Installation

3.1. Preparation

  • Verify that the selected float switch model matches your system's voltage and power requirements.
  • Ensure the liquid to be monitored is chemically compatible with polypropylene material to prevent degradation.
  • Check that the mounting port on your tank or container matches the M12 x 1.25 thread specification of the float switch.

3.2. Installation

  • Install the float switch horizontally on the tank wall using the threaded connection.
  • Ensure proper sealing using a suitable gasket or sealing tape to prevent any leakage.
  • Orient the float according to the required normally open (NO) or normally closed (NC) configuration for your application.

3.3. Electrical Connection

  • Connect the two lead wires in series with your control circuit.
  • Ensure that the load connected to the switch does not exceed the specified maximum voltage, current, and power rating.
  • Always disconnect power supply before performing any wiring or maintenance.
Wiring instructions diagram for connecting the float switch to a relay
Figure 6: Wiring instructions diagram. Connect the blue line to Output 220V and the red line to Input 220V. A small relay is recommended for high-power loads.

Important Note on Relays: Since the switch contact capacity inside the float ball is small, float switches cannot directly control water pumps, solenoid valves, or high-power relays/contactors. A small relay (such as hh52p/hh54p) is required to prevent misoperation, especially if the load involves motors or high-power equipment.

4. Operation

4.1. Basic Operation

When the liquid level reaches the float position, the internal magnetic reed switch changes its state (from open to closed or vice-versa, depending on orientation). The output signal generated can be used to control various devices such as relays, alarms, or PLC digital inputs.

4.2. Commissioning and Verification

To verify the switching function, gradually fill or drain the tank during commissioning and observe the corresponding change in the output signal or controlled device state.

5. Maintenance

5.1. Storage

  • Store the float switch in a dry and well-ventilated environment.
  • Keep away from direct sunlight, strong acids, alkalis, or solvents when not in use.

5.2. Cleaning

  • Clean the float and housing periodically to prevent debris accumulation, which can affect accuracy and operation.

5.3. General Care

  • Do not disassemble the sealed reed switch housing.
  • If a malfunction occurs, replace the entire unit. Internal components are not user-serviceable.

6. Troubleshooting & User Tips

6.1. Troubleshooting

  • Switch not activating: Ensure the liquid level is within the float's range. Check electrical connections and ensure power is supplied.
  • Inconsistent readings: Clean the float and housing to remove any debris. Verify the liquid's specific gravity matches the switch's design.
  • Switch failure with high-power devices: Ensure a relay is used for controlling high-power loads like pumps or motors. Direct connection can damage the switch.

6.2. User Tips

  • Relay Use: Always use a small relay when connecting the float switch to high-power devices (e.g., water pumps, solenoid valves) to protect the reed switch from overload.
  • Chemical Compatibility: Before installation, confirm that the liquid in your application is chemically compatible with polypropylene (PP) to ensure long-term performance and prevent material degradation.
  • Fixed Float Position: Note that the float position is fixed and cannot be adjusted after manufacturing. Ensure the correct model is selected for your desired switching point.
  • Regular Cleaning: Periodically clean the float and the switch housing to prevent debris accumulation, which can lead to misoperation.

7. Warnings and Precautions

  • Electrical Safety: Risk of electric shock if used with high voltage circuits. Always disconnect power supply before installation, wiring, or maintenance.
  • Rated Limits: Do not exceed the specified maximum voltage, current, or power rating to prevent overheating or fire hazards.
  • Chemical Compatibility: Avoid use in liquids that may chemically degrade polypropylene, as this can lead to product failure.
  • Environmental Conditions: Do not use the device in environments exceeding its defined temperature range or where strong vibration or mechanical impact is present during operation.
  • Wiring Insulation: Ensure proper insulation of all wiring connections to prevent short circuits and electrical hazards.
  • Explosive Atmospheres: This device is not suitable for explosive atmospheres unless additional certified protection measures are explicitly implemented.
  • Grounding: Ensure proper grounding of all associated equipment.
  • Children: Keep out of reach of children.
  • Disposal: Follow WEEE (Waste Electrical and Electronic Equipment) directives for proper disposal of electronic waste.
