3. Vörulýsing
3.1 Almennt
The HTS401 is a RH / T sensor for demanding and challenging applications in climate control. It is available for wall or duct mounting as well as with a remote probe, for indoors or outdoors
Vara afbrigði
Three different HTS401 types provide a broad range of options for measurement tasks:
Available Quantities, Units and Measuring Ranges
rapidX Pluggable Sensing Module
Sensor types are available that feature the pluggable RH / T sensing module with rapidX technology. The module can easily be exchanged on-site and even during operation without switching off the HTS401 sensor (hot-swap).
Please refer to chapter 6.1 Sensing Module Replacement for more details.
Configuration and Adjustment
The optional USB-C configuration stick and the free PCS10 Product Configuration Software facilitate easy configuration and adjustment of the HTS401. Please refer to chapter 5.2 PCS10 Product Configuration Software.
Framboð
The HTS401 power supply depends on the design and is provided via a cable gland directly to the screw terminals on the circuit board. For the details, please refer to chapter 3.3 Electrical Connection and to the “General” section of chapter 8 Technical Data.
Framleiðsla
The measured / calculated data is available on two freely selectable and scalable analogue outputs or on the digital RS485 interface with Modbus RTU protocol.
For the details, please refer to chapter 3.5 Outputs.
Efni
The HTS401 enclosure is available in either polycarbonate or die-cast aluminium. For polycarbonate enclosure, the probe tube is also made of polycarbonate. A duct mount type enclosure from die-cast aluminium comes with a stainless steel probe tube. The filter options are fully available for all types and materials.
Skjár
An optional display for on-site monitoring of the measuring values allows for a quick overview of the prevailing conditions in the process. Please refer to chapter 3.8.1. Display.
Þrýstijöfnun
The HTS401 performs pressure compensation of all humidity-related quantities. A pressure value of
1013.25 mbar is set at the factory. If the actual pressure deviates from the factory setting, the desired working pressure value may be entered via PCS10 Product Configuration Software and via Modbus command for the version with RS485 digital interface.
Heating Modes against Chemical Contamination and High Humidity
Automatic ReCovery (ARC) is used to outgase chemical pollution and thus eliminate possible drift effects, especially outdoors. This is achieved with an intense heating of the RH / T sensing element. The function can be perfectly tailored to the application requirements being triggered:
▪ Manually via PCS10
▪ By a certain cyclic time interval configurable via PCS10, or ex works
▪ Via RS485 digital interface
The Condensation Guard (CG) is designed for applications with variable humidity where condensation may occur for short periods of time. The CG protects the RH / T sensing element by targeted heating. This prevents temporary condensation and its negative effects on the measurement results. The CG heating is triggered by a predefined RH threshold, factory set via order code and configurable with PCS10.
3.2 Mál
3.3 Rafmagnstenging
The HTS401 features screw terminals on the electronics board for connecting the power supply and the outputs. The cables are fed into the enclosure through the M16 cable gland.
TILKYNNING
Make sure that the cable glands are closed tightly for the power supply and outputs cable. This is necessary for assuring the IP rating of the enclosure according to HTS401 specification, as well as for stress relief at the screw terminals on the HTS401 board.

3.5 Úttak
The measured data is available on two analogue outputs or via digital RS485 interface with Modbus RTU protocol. The freely scalable analogue outputs both are either current (4 – 20 mA, 2-wire or 3-wire) or voltage (0 – 10 V or 0 – 5 V). Configuration is selected at the time of order and can be changed in the field via PCS10 Product Configuration Software and USB-C configuration stick (HA011070).
Optionally, an LC display with up to three lines is available. For details, please refer to chapter 3.8.1. Display.
3.6 Configuration Interface
The HTS401 is ready to use and does not require any further configuration. The factory setup of HTS401 corresponds to the specified order code. Please refer to the datasheet at www.epluse.com/hts401.
The HTS401 features a USB configuration interface for configuration, adjustment and firmware update via PCS10 (please refer to chapter 5 Setup and Configuration).
If needed, the factory setup can be changed via
- Free PCS10 Product Configuration Software.
Please refer to chapter 5.2 PCS10 Product Configuration Software. - Modbus RTU protocol (if the RS485 option is selected).
Please refer to chapter 5.3 RS485 Digital Interface.
ATHUGIÐ
- The full scope of configuration is available with the PCS10.
- Configuration with the Modbus RTU protocol only refers to the Modbus communication settings.
3.7 hitastillingar
3.7.1. Yfirview
The intelligent heating modes on the HTS401 are available for all types with 3-wire output: A2/A3/A19/J3.
3.7.2. Automatic ReCovery (ARC) against Chemical Pollution
When capacitive humidity sensing elements are exposed to chemical pollution (e.g. detergent residues), foreign molecules can contaminate the sensing element and distort the measurement reading of the sensor. With the ARC function, these impurities can be evaporated from the sensing element by brief and intensive heating.
ATHUGIÐ
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 ARC function is characterised by its triggers and parameters which are described below. All the parameters have factory default settings according to the order code and can be modified via PCS10 Product Configuration Software.
ARC Parameters
Heating duration: Defines the time in which the monolithic measurement cell is intensively heated. A heating time of at least 20 minutes (20 min = factory setting) is recommended when unknown chemical pollution has occurred.
Recovery duration: The cool-down time is necessary for the sensing element to get back to ambient
temperature. The cool-down time depends significantly on the prevailing flow velocity at the measuring point and the resulting heat dissipation.
The factory setting for the recovery duration is 6 minutes, which is suitable for processes involving an air flow of around 3 m/s (590 ft/min) and a residual temperature difference of less than 0.5 °C. Please refer to Table Tab. 9 for the recommended cool-down time at different air velocities.
During the ARC cycle (heating and cool-down time), the RH / T values at the outputs are frozen. The measuring values at all outputs are kept at the values that were valid at the time the process started. At the end of the cycle, the outputs (analogue and digital) and display return to normal operation.
For Modbus types, the remaining ARC process time in seconds is available in the register 0x1FD (510DEC).
ARC Function Triggers
Manual: A manual start of the ARC function is recommended when ▪ chemical pollution on the sensing element is expected (cleaning/sterilization) or ▪ measurement readings deviate significantly from a calibration reference.
UPPLÝSINGAR
The manual ARC start can also be triggered via RS485 command.
At power on: The ARC cycle starts immediately at the device’s power-on and is carried out once.
Cyclic: ARC can be configured to start periodically at a certain time interval. The feature properties are selected at the time of ordering and can be changed via PCS10.
ATHUGIÐ
The cyclic ARC start can be ordered with a cycle interval of 24 h and start at power-on.
To achieve this behaviour with the PCS10 Product Configuration Software, both, the “at power on” and the “cyclic” options have to be activated.
Periodic heating shall be used to minimize drift effects in applications with high chemical pollution and outdoor operation. The ideal cycle time depends on the type of pollution and its concentration and has to be determined empirically. For general use or as a starting point, an interval of 24 hours should be used.
Indications on the Optional Display
As soon as the ARC cycle starts, the optional display shows the following indications for the entire heating duration:
▪ “heating: 0” when ARC trigger “At power on” is enabled
▪ “heating: 1” when ARC trigger “Start ARC now” or “Cyclic” is enabled During the subsequent recovery duration, the frozen measurement values are displayed.
After recovery, the display returns to normal operation.
ATHUGIÐ
If the defined cool-down time is too short, the measurements may be incorrect
3.7.3. Condensation Guard (CG) against Temporary Condensation
Temporary condensation on the sensing element in highly humid environments is eliminated when a specified RH trigger (factory setting: acc. to order code) is reached. By intensive heating of the sensing element for 10 seconds, occurring dew is evaporated. The sensing element cools off quickly within approximately 3 minutes and returns to its measurement function.
If condensation is still detected after the CG cycle, it restarts immediately or after the predefined lock time
During the complete heating and cool-down process, the values all at the outputs are frozen. In other words, the measuring values at the outputs are kept constant during the CG cycle.
The CG function can be preconfigured using the order code options. The lock time is configurable.
ATHUGIÐ
The lock time has to be set according to the application needs. A lock time too short might result in permanent freezing of the outputs.
Via the PCS10, the following CG parameters can be configured:
▪ Humidity threshold
▪ Cool down time
▪ Lock time
ATHUGIÐ
When heating has ended, the system blocks any subsequent heating for 30 minutes. That means if the ambient humidity remains above the defined set point after the initial heating, the next CG cycle starts again after 30 minutes.
3.8 Valfrjálsir eiginleikar
3.8.1. Skjár
The optional display is available for all HTS401 types.
Per factory setup, the display shows the two measurands selected for output 1 and output 2 for analogue versions (according to the ordering code). Versions with digital interface indicate RH and T.
The display layout can be modified via PCS10. The configuration options include the display of 1, 2 or 3 lines, and the displayed quantities. Please refer to chapter 5 Setup and Configuration for details.
UPPLÝSINGAR
The display is available as a spare part, intended for both, replacement and retrofit. This means that also HTS401 sensors purchased as non-display variants can be equipped with a display. Simply replace the cover with one that has a display. The display is connected to the circuit board via a FFC cable. No configuration is necessary.
ATHUGIÐ
It is possible to convert a display variant to a non-display variant without any configuration.
ATHUGIÐ
The HTS401-M1xA6 (4 – 20 mA, 2-wire version) with display operates correctly only if both outputs are connected.
4. Uppsetning og uppsetning
4.1 Almennt
For mounting the cable gland (in the scope of supply) onto the HTS401 enclosure, use a matching wrench.
When using HTS401 with a conduit connection for the North American market, carefully open the blind at the top of the enclosure using a flat screwdriver. Take good care to avoid damaging the electronics inside the enclosure.
The conduit adapter is not included in the scope of supply. The M16x1.5 opening for the cable gland shall be tightly closed using the blind plug included in the scope of supply (please refer to also chapter 3.2 Dimensions).
4.2 Recommendations for Accurate Humidity and Temperature
Mæling
The sensing elements and output electronics of an HTS401 are incorporated in a compact enclosure and are designed to be mounted in a specific direction.
Any heat generated by the electronics rises upwards, so the sensor tube must point downwards to prevent the heat from affecting the measurement.
Any residual self-heating effects are compensated in typical operating conditions (e.g. supply voltage: 24 V DC, load resistance for current types: 250 Ω, air velocity at measuring point: 0.2 m/s (39 ft/min)).
For best measurement results, the HTS401
- must be installed so that the RH sensor is pointing downwards whenever possible
- must be installed in an environment where the medium to be measured flows sufficiently around the RH/T sensing probe.
- shall not be placed in the proximity of heat sources such as heating radiators or fan heaters.
For HTS401 wall mount types please mind the following rules for sensor positioning. Mount the sensor: - 2 m (6.6 ft) away from inlets and outlets
- In a place where the air can circulate freely. Best accuracy is achieved with a velocity of min. 0.2 m/s (39 ft/ min) of the air surrounding the probe. Depending on the installation position, flow direction and flow velocity, the accuracy may decline.
- Not in places where heat accumulation may occur
- Not in places where draughts may occur
HTS401 duct mount types must be installed in a way that temperature gradients due to thermal coupling, which
lead to incorrect measurements, are avoided along the sensor tube.
HTS401P remote probe types
- In case the HTS401P remote probe is not entirely located in the environment to be monitored, large temperature differences along the probe will lead to temperature gradients. These will have an influence on the accuracy.
Therefore, it is of paramount importance to minimize the temperature gradients. The biggest part of the probe shall be located in the target environment and the rest shall be thermally well insulated. - For outdoor applications, the HTS401P shall be equipped with a radiation shield (HA010502 without enclosure supporting plate) which provides protection from rain, snow and ice. This also causes a natural ventilation which largely prevents overheating of the probe in the sun and thus a distortion of the measured values.
- Best accuracy is achieved with a velocity of min. 0.2 m/s (39 ft/min) of the air surrounding the probe. Depending on the installation position, flow direction and flow velocity, the accuracy may decline. The following table gives a concise overview.

TILKYNNING
When reading information that spans multiple registers, it is always necessary to read all registers, even if the desired information requires less.
TILKYNNING
To obtain the correct floating point values, both registers have to be read within the same reading cycle. The measured value may change between two Modbus requests. This can cause inconsistencies in the exponent and mantissa.
UPPLÝSINGAR
The Modbus function codes mentioned throughout this document shall be used as described in chapter 6 of of MODBUS APPLICATION PROTOCOL SPECIFICATION V1.1b3, available at https://www.modbus.org/.

5.4 Modbus skráningarkort
The measurement data is saved as 32 bit floating point values (data type FLOAT32) and as 16 bit signed integer values (data type INT16).
5.5 HTS401 Modbus Backwards Compatibility to EE210 and EE212
The HTS401 can directly replace an EE210 / EE212 sensor. This is valid for Modbus types as well as for all types with analogue output.
The measurement data is saved as 32 bit floating point values (data type FLOAT32) and as 16 bit signed integer values (data type INT16).
ATHUGIÐ
For full backwards compatibility, it is necessary to chose the correct unit via ordering code.
5.6 Configurable Custom Modbus Map
It is possible to map measured value / status registers arbitrarily to a block of up to 20 registers provided for this purpose. This means that registers of interest can be mapped to a range of consecutive registers, so that important values can be queried with a single command in one block.

The register block for the configuration of the customisable Modbus map consists of the registers 6001 (0x1770) to 6010 (0x1779). For the block-wise query of the measured values behind Modbus registers 3001 (0xBB8) to 3020 (0xBCB), the firmware accesses this configuration area and thus gets the information which measured value/status registers are to be output. A maximum of 10 user-defined registers can be mapped. The table below shows an example:
5.7 Stöðuvísun tækis
The HTS401 features a status register that contains all status and error information. The status information can be read from Modbus register 602 (0x259). Errors are displayed in bit-coded form. If an event is present, the corresponding bit is set to 1.
If a critical error occurs, all Modbus values are set to NaN (according to IEEE754 for data type FLOAT32) or to 0x8000 (INT16).
Measured values out of range are limited by the corresponding limit value.
5.8 Modbus RTU Example
The HTS401’s Modbus address is 49 [0x31].

Extreme working conditions such as highly polluted, aggressive and chemically contaminated environment might require periodical maintenance of the device. The modular design facilitates maintenance. Replacing the sensing module under the above conditions is a standard maintenance operation, with the sensing module being a wear component. Any warranty claims relating to measurement drift or sensing module failure caused by the harsh working environment are excluded.
ATHUGIÐ
For a newly ordered HTS401M sensing module, the inspection certificate according to DIN EN 10204-3.1 is available online only from https://certificates.epluse.com. The serial number is lasered onto the module as a 2D bar code. Please refer to Fig. 10.
Málsmeðferð:
1. Remove the filter cap by turning it counter-clockwise.
2. Remove the sensing module by pulling it straight out from the probe.
3. Plug the new HTS401M sensing module into the output unit.
4. Screw the filter cap fingertight onto the probe.
6.2 Filter Cap Exchange
In a dusty, polluted environment it might be necessary to replace the filter cap once in a while. In most of the cases, a clogged filter shows visible contamination or dirt. Longer response time of the measurement also indicates a clogged filter cap. In such cases, replace the filter by a new, original one, refer to the Accessories datasheet.
Málsmeðferð:
1. Turn the filter cap counter-clockwise for removing it.
2. Install the new filter cap fingertight by turning it clockwise.
6.3 Display Change
When connecting the display’s FFC cable to the HTS401 electronics board, please observe the correct orientation. The blue cable stiffener needs to be positioned on the left side as shown in Fig. 12.
TILKYNNING
Disconnecting or connecting the display while the HTS401 is powered may cause damages to HTS401 and to the display.
Always switch off the HTS401 before exchanging the display.
6.4 Self Diagnosis and Error Messages
The PCS10 information section contains error messages from HTS401, if errors occur. The following table shows the error codes and their meaning. Please note that this table directly corresponds to Tab. 18 Device status indication in chapter 5.7
6.4.1. Villuboð í PCS10
6.4.2. Error Messages on the Display
6.4.3. Error Indication on the Analogue Output (NAMUR)
The HTS401 features an error indication on its analogue outputs according to the NAMUR NE 043 recommendations (Standardization of the Signal Level for the Failure Information of Digital Transmitters, Edition 2003-02-03, see www.namur.net/en/recommendations-and-worksheets/current-nena.html).
ATHUGIÐ
During a rapidX module exchange, communication between the HTS401 and the RH / T sensing module is lost. This is interpreted as an internal failure, resulting in NAMUR signal levels being applied to the outputs.
Once the module exchange is complete, the outputs will return to their normal state.
6.5 Viðgerðir

For best accuracy, every E+E RH and T sensor is multi-point factory adjusted and calibrated in a highly stable
RH / T reactor. Using a high-precision dew point mirror as reference, the overall uncertainty of the factory calibration Ucal is minimal.
Heildarmælingaóvissa Uttotal fyrir E+E skynjara er reiknuð í samræmi við EA-4/02 (European Accreditation, Evaluation of the Measurement Uncertainty in Calibration) og með GUM (Guide to the Expression of Uncertainty in Measurement) sem hér segir:
Utotal……..total accuracy incl. factory calibration
Ucal……….uncertainty of the factory calibration
uaccuracy….accuracy of the measurement device
k…………..coverage factor k=2, corresponding to a confidence level of 95 %.
For external calibrations, Utotal is to be used as the evaluation criterion. The calculation does not include effects
due to long-term drift or chemical exposure.
