Overview
Characteristics
Operating
Principle &
Composition
HCC-95P(-Ex) Series is a capacitance type level switch and it detects a level of medium
by sensing of capacitance value change by dielectric constant of each medium.
Where an air surrounding the electrode probe is replaced by other medium, the
capacitance value is changed according to the dielectric constant of the medium. Once
the electrode probe is touched by the medium, the capacitance value is increased and
the level switch activates relay output by converting of the changed capacitance value to
the electronic signal.

Installation
Precautions
for
Installation
- If more than one level switch is installed in a tank, the distance between each probe
shall be at least 300mm apart. (If the distance between probes is short, it may be
affected by the interconnection of the instrument, causing unstable operation.)
- For side mounting installation, an inactive rod shall be located at least 50mm inside of
tank, and it is recommended that the probe be tilted by 15 degrees to the horizontal
surface. (A foreign object between the nozzle and the probe may cause malfunction.)
- Probe shall be installed to avoid the inlet side of the measuring instrument, and the
protector shall be installed to prevent damage to the probe. Protector shall have
sufficient area to protect the sensor from incoming medium and be installed at a
distance that does not affect sensor operation.
- For side mounting installation, the cable entry shall be installed facing the ground to
maintain the waterproof function.
- When installing on the low level, carefully install the dead stock and material bridge.
- If the medium in the tank is liquid, set the Time Delay appropriately to delay the
operation of the output relay.
- For outdoor installation, it is recommended to install the sun cover to avoid the effects
of temperature increases.
- In case of tank with stirrer, the probe shall be installed at a safe distance from the stirrer.
The capacitance type level switch can be installed in screw (PT, NPT, PF, etc.) and flange
(ANSI, JIS, DIN, etc.) as well as tri-clamp and other various locations.
Pay attention to the following matters during installation.
■Side Mounting Installation
Highly sensitive measurement is available because it measures the level by whole of
probe but it shall be installed slopingly, forwarding of sensor to the bottom in order to
avoid a malfunction caused by build-up of the medium on the sensing probe.
■Top Mounting Installation
This installation is not much affected by build-up of the medium on the probe but the
sensitivity is lower than side mounting because it measures the level by the end of probe
only, and it is not suitable to detect a level of the medium which has a low dielectric
constant.

Precautions
for Attachment
Wiring
■Connect correctly AC(90~240V) or DC(+24V) power to the power specification.
■Make sure to connect the DC power with correct polarity(+, -).
■Do not connect the wire with the power connected.
■It provides DPDT output by default, wired COM and N.O terminals when using the
high alarm.
■External grounding shall be completed.
In case of Ex-proof products, apply the power after tightening the cover after wiring.
■When installing the sensor, avoid shaking or obstacle.
■Do not install in openings that are prone to severe fluid flow, mechanical damage, or
chattering.
■Check the specification of temperature and pressure generated inside the tank.
■Condensation may occur if the temperature of the housing differs significantly from the
ambient temperature, so dehumidifier shall be filled or ventilated(gortex) before use.
■Connect the flanges or bolts with the same specifications.
■Make sure to insert gaskets between flanges. (Select the gaskets in consideration of
the temperature of the content and the pressure inside the container.)
For Ex-proof products, it shall be installed with an appropriate grade for environment.

(Ex-proof)
■Check the level and presence of measure object in the tank before removing it.
■Wear gloves when removing it, to prevent a burn.
■Unlock the lock key before removing the cover. (Ex-proof)
■Disassemble work shall be done with the power off.
■Make sure that any O-ring or gasket is not damaged while opening or closing the
cover of product.
■Check whether the product would be installed in the Ex-proof zone, and use the
appropriate product.
■Do not bend or extend the sensor randomly.
■Make sure to install the product and the cover first before supplying the power.
■Do not use if the temperature range of the installation exceeds -20℃to +60 ℃.
■Do not use if the protection grade requires a higher grade than its product. (IP66 for
AL. Housing or IP65 for PBT Housing)
■Do not use where vibration is present.
■Use the cable gland connection or metal pipe line lead-in on the wire inlet, and use a
product with equivalent Ex-proof certificate to connect it with the external line lead-
in method.
■For non-use external wire inlet, use a closed plug that passes safety certificate above
equivalent performance with the product.
The life span of key parts depends on user’s environment and can be used optimally
through periodic check. Therefore, regular inspection ensures optimal performance of
product, so take regular inspection and maintenance at least every year. Inspection of the
appearance of the product shall be visually checked to see if there is any damage, and the
attachment of the medium or foreign substances to the sensor will make it worse, so they
shall be removed regularly. Be careful not to damage Teflon part during removal.
■Failure Check
1) Is power voltage connected correct?
2) Is power voltage supplied according to specifications correct?
3) Is cable wiring correct?
4) Is the Fail-Safe Mode setting correct?
5) Does the green LED turn on?
Turn off the power of the product for maintenance.
In an explosion area, do not disassemble when power is applied.

Precautions
for Grounding
(Ex-proof)
Safety and
Environment
■The grounding has an external and an internal grounding. When connecting to an
external ground, the ground wire shall be 4㎟(4mmSQ). (The internal grounding shall
be wiring to the same specification as the connected cable.)
■Precautions for Use
- Make sure to connect the product and vessel using required tools for sure.
- Keep the lock key safe and make sure that it is locked.
- Do not apply high impact to the product.
■Precautions for Wiring
- Make sure to connect contacts with the correct terminals. (Refer to Wiring)
- Wire and supply the power to the device 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 amplifier 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.
