1.2 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

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.

contamination. In addition, it is perfectly protected by the E+E proprietary coating.

Different heating modes of the monolithic RH and T sensing element allow for best adaption to the specific

needs of each measuring task. Furthermore, types T7, T17 and T28 offer a dual heating system (probe body

and sensing element are heated) to prevent condensation on the RH sensing element and on the probe body for

continuous high humidity operation.

The measured data is available on two freely scalable analogue outputs, on the RS485 (Modbus RTU) or

Ethernet-PoE (Modbus TCP) interface and on the alarm (relay) outputs. The configuration and the RH and T

adjustment of the HTS801 can be performed with the free PCS10 Product Configuration Software. An optional

3.5” colour display with push-buttons is available for configuration and visualisation.

The HTS801 with PC7 option (see ordering guide) features the intelligent pluggable rapidX probe, which enables

a plug-and-play probe exchange.

The optional Automatic ReCovery (ARC) module allows for external triggering of the heating functionality.

3.4.2. AutomaticReCovery(ARC)againstChemicalPollution

When capacitive humidity sensing elements are exposed to chemical pollution (e.g. detergent residues), the presence

of foreign molecules can distort the measurement reading of the sensor. With the ARC function foreign molecules

can be evaporated from the sensing element by brief and intensive heating.

All HTS801 types support the ARC function.

PLEASENOTE

Before a recalibration is done after an ARC cycle, reconditioning of the sensing element is recommended.

For best reconditioning, please allow 2 free calibration cycles between 15 %RH and 90 %RH in steps of

~20 %RH and 20 min stabilisation time.

The start of the ARC function can be triggered as follows:

Manual: by using PCS10 or via display and push-buttons. A manual start of the ARC function is recommended when

 measurement readings deviate significantly from a calibration reference.

Cyclic: by using PCS10 or order code option ARC1 (24 h), ARC can be configured to start periodically at a

certain time interval.

The cyclic option can be extended to include an automatic start at power on. This function can be switched on

and off via PCS10, display and push-buttons or using order code option ARC2 (24 h power on).

Periodic heating shall be used to minimize drift effects in applications with high chemical pollution. The ideal cycle

time depends on the type of pollution and its concentration and has to be determined empirically.
