When the level sensor connected to HLC-400 detects a liquid in the tank, a leakage
current flow and it is sensed by leakage current sensing circuit, and transistor is
activated. Accordingly, relay contact is changed and it can be used for alarm and/or
control signal.
■Easy to install (DIN Rail Type)
■Compact size
■Operating can be checked through LED lamp
HLC-400 is a Level Control & Alarm Unit that controls and alarms by combining with
the level sensor (HE, HQ, HR Type) of the storage of tank. The signal of the level sensor
can function as the upper and lower alarm of liquid through HLC-400, and the product
can be installed inside the control panel.

Connection Diagram
■It is recommended to use washers to prevent a loosening when the product is fixed using bolts.
■Wiring shall be performed after checking of wiring diagram described in the manual or sticker.
■Make sure that the power source whether it is AC 110V or AC 220V.
■It is recommended to use AWG 13 or 14 cable between the controller and level sensor, and use
shield cable in case that the distance between the controller and level sensor quite long(several
hundred meters ~ 500m) and for low conductivity medium. (Non-recommendation cables may
result in some differences in operating and level sensing distances.)
■Check the LED color after applying of power.
■Power shall be applied after completing of installation.

Safety and
Environment
Failure Check
and Solution
■Precautions for Use
- Do not disconnect the cable during use.
- Do not disconnect the product during use.
- Do not apply high impact to the product.
■Precautions for Wiring
- Make sure to wire contacts correctly. (Refer to Wiring)
- Wire and supply the power to the product after checking the specifications.
- Incorrect power voltage may cause damage to the product.
- Pay attention to prevent electric shock.
■Disposal of Product
- Make sure to separate the PCB and main unit from housing before disposing the products.
No part (ex. Mercury Switch) has influence on the environment, so no special attention is
required.
■Relay contact does not work
- Check whether the LED lamp is on/off.
- Check the cable connection.
- Check the input voltage.
- Check the level sensor wiring cable.
■Controller is normal, but not working
1) Electrode Type Level Switch
- If there is foreign matter or sediment such as lime on the bottom of tank, it may
cause malfunction.
- Too low liquid conductivity can cause malfunction. (ex. Distilled Water)
- When wiring between controller and electrode is far apart, it may cause malfunction.
- Please refer to the cable recommendations between the controller and the sensor for
installation precautions (Page 5).
2) Float Type Level Switch
- Check that the float floats normally.
- Check the signal when the float operates normally.
