Safety Instructions
1.2.1.
General Safety Instructions
NOTICE
Improper handling of the device may result in its damage.
▪.
The HTS801 enclosure, the sensing probe and the sensing module shall not be exposed to unnecessary
mechanical stress.
▪.
Do not apply the supply voltage to the RS485 data lines.
▪.
The HTS801 electronics is sensitive to electrostatic discharge (ESD), appropriate protective measures shall
be taken when touching it.
▪.
When replacing the filter cap make sure not to touch the sensing elements.
▪.
The device must be operated with the filter cap on at all times.
▪.
For sensor cleaning and filter cap replacement please see "Cleaning Instructions" at www.epluse.com.
▪.
Installation, electrical connection, maintenance and commissioning shall be performed by qualified
personnel only.
▪.
The devices are designed for the operation with class III supply (EU) and class 2 supply (NA).
▪.
The power supply must be switched off before opening the housing.
▪.
Use the HTS801 only as intended and observe all technical specifications.
▪.
An existing Ethernet connection must be disconnected before opening the enclosure.
1.2.2.
Alarm Module with Voltages >50V (Option AM2)
WARNING
Notice signals danger to objects or data. If the avoidance instructions are not observed, damage to property
or data may occur.
▪.
The optional alarm module is isolated from the low-voltage side of the HTS801 by a special partition; this
must remain fitted at all times in the back section of the enclosure.
▪.
The HTS801 enclosure must be tightly closed during operation. An open enclosure corresponds to IP00
and exposes components carrying dangerous voltage. Any work (maintenance for instance) on the device
may be performed by qualified staff only.
1.2.3.
Integrated power supply 100 - 240 V AC (Option AM3)
WARNING
Notice signals danger to objects or data. If the avoidance instructions are not observed, damage to property
or data may occur.
▪.
The HTS801 enclosure must be tightly closed during operation. An open enclosure corresponds to IP00
and exposes components carrying dangerous voltage. Any work (maintenance for instance) on the device
may be performed by qualified staff only.
1.2.4.
Intended Use
The HTS801 sensors are designed to meet the highest demands of stable and highly accurate measurements of
relative humidity (RH) and temperature (T) under the most challenging conditions The RH and T sensor handles a
wide.range.of.applications.from.-80.°C.(-112.°F).up.to.180°C.(356.°F).and.300.bar.(4 350.psi),.even.under.harsh.
environmental conditions such as constant high humidity and chemical contamination.
With different intelligent operating modes, HTS801 can be perfectly tailored to the specific needs of each
measurement task. Depending on the type and duration of the exposure (humidity, chemicals), the monolithic RH
and T sensing element is exposed to an appropriate heating strategy.
The use of the HTS801 in any other way than described in this manual bears a safety risk for people and the
entire measurement installation and is therefore not allowed.
The manufacturer cannot be held responsible for damages as a result of incorrect handling, installation, and
maintenance of the equipment.
