1. Overview
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.
2. Operating Principle & Composition
When 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.

4. Wiring and Amplifier Composition
■ 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.

5. Precautions
■ Precautions for Installation
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 lower dielectric constant.

■ Precautions for Grounding
▶ When connecting to an external ground, the ground
wire shall be 4 ㎟(4mmSQ).
■ Failure Check & Maintenance
▶ Inspection of 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?
■ User Training
Make sure that the ambient temperature of housing is kept at -20℃ ~ +60℃. Ex-proof
products are designed according to Article 34 of the Industrial Safety and Health Act and
Article 58.4 of the Enforcement Rules of the same Act. (Refer to Instruction Manual for details.)
◈ More product information can be acquired at our website. (www.hitrol.com)
Make sure to insert a washer if the terminal lug is
removed from ground terminal and then re-connected.
(Loosening prevention)
Turn off the power of the product for maintenance.
In an explosion area, do not disassemble when power is supplied.
Do not apply a non-ex-proof product in an Ex-proof zone. Ex-proof
products can only be installed at zone 1 and 2 of environment. It shall
be installed in compliance with the ex-proof temperature rating and
the applied fluid temperature.
