Maintenance ■ Inspection of products
The main inspection part of the HR-10L (Ex) series is Reed S/W.
The life span of the main components depends on the environment and can be used in
optimal condition through periodic checks. Therefore, users should perform maintenance
through regular inspections at least once a year. Using a Digital Multimeter, the inspection can
be carried out simply as follows.
- Select the buzzer of the Digital Multimeter and connect it to the N.O. and Com
terminals of the product.
- It is normal when the buzzer sounds at the point of contact by moving the magnet
up and down at the body of HR-10L.

HR-10L Series
HITROL CO., LTD. 7
- If checking contact status with resistance, the Digital Multimeter represents 0 ohms
when it represents a normal close (NC) and displays infinite when it is normal open
(NO).
■ Precautions for Installation
- If there is explosive gas atmosphere, do not open the cover.
- Unlock the lock key (Set screw) before removing the cover. (Ex-proof)
Precaution for
Transportation,
Assembly
and
Installation
■ Precaution for Installation
- As it is assembled and shipped to a level gauge (HLG-100F), no special
precautions are required for installation.
- Do not shock the product when transporting or dismantling it.
■ Precaution for Inserted External Wire (IP65)
- Use the cable gland connection or metal pipe line lead-in in the wire inlet.
- 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 close plug that passes safety certificate
above equivalent performance with the product.
■ Precaution for Grounding
- The grounding has an external and an internal grounding. When connection to
an external ground, the ground wire shall be 4mm2 (4mmSQ).
- The internal grounding wire shall be the same size as the power line, and the
size of the internal grounding terminal lug shall be 3.1mm2 (3.1mmSQ). If the
power line is larger than 3.1mm2, connect the ground wire without terminal lug.
<Warning> Make sure to insert a washer if the terminal lug is removed from
ground terminal and then re-connected.
Safety and
Environment
■ Caution for Use
- Make sure to connect the product and the container using the required tools.
- Keep the lock key safe and make sure that it is locked.
- Do not cause high impact to the product.
■ Cautions for Wiring
- Make sure to wire contacts correctly (Refer to Wiring)
- Internal ground (inside product housing) and external ground shall be
connected.

■ Disposal
- M
