Overview
Characteristics
Operating
Principle and
Composition
When the level switch connected to HLC-200 Series 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
■Socket structure type for freely detachment
■Operating can be checked through LED lamp (High: Red, Low: Green)
■Sensitivity can be adjusted at the site if the sensor is too much sensitive to the conductivity
or foam of the liquid. (HLC-200A)
HLC-200 Series 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 control the upper and lower alarm of liquid and automatic supply of liquid
through HLC-200 Series, and the product can be installed inside the control panel.

■Sensitivity Adjustment
Use only with electrode sensors.
Note that factory standard setting is for high sensitivity.
Sensitivity
Adjustment &
Recommended
Tool (HLC-200A)
■Recommended Tool
- When adjusting SENS. (Sensitivity), use the driver (-) 2.5x75 or less or (+) 00x75.
- Alarm Lamp: The red light is on when the liquid is detected, and the green light is on
when the liquid is not detected.
- Sensitivity Dial: It is a function to adjust the sensitivity in condition that it is too
sensitive to the conductivity of the medium or foam. Turning counter-clockwise is for
higher sensitivity and clockwise is for lower sensitivity.

Maximum available adjustment range of potentiometer using for the sensitivity
dial is approximately 260°. (±130°based on 9 o’clock direction)
Pay attention to use it because it can be damaged if it is adjusted over the range.

Failure Check
and Solution
■Precautions for Use
- Do not disconnect the cable during use.
- Do not disconnect the product from the socket 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.
■Remove it with the power disconnected.
■Remove in reverse order of installation. (Power off Release the Locker Body
Disconnection Wiring Disconnection Socket Disconnection)
■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, AC 220V, or DC +24V.
■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 is 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. (High: Red, Low: Green)
■Power shall be applied after completing of installation.
■Relay contact does not work
- Check whether the LED lamp is on/off.
- Check the cable connection.
- Check the input voltage.
- Check the connection between the body and the socket.
- Check the level sensor wiring cable.

■Product Identification
- The product identification mark is attached onto housing and shows the model
name, serial number, and matters regarding input/output. The serial number is a
unique manufacturing number for the identification of products.
■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 9).
2) Float Type Level Switch
- Check that the float floats normally.
- Check the signal when the float operates normally.
- It is attached to the front of the product and the
model name and input/output information are
indicated.
- It is attached to the bottom of the product
and the serial number is indicated.
- It is attached to the top of the product and
means it has passed the internal quality
system.
