1 INTRODUCTION

The Delt a OHM wi reless data logging system allows several physical quantities to be mon i tored in a large variety of application fields. Data loggers are available for t he monitoring of:

• Temperature

• Humidity

• Atmospheric pressure

• Differential pressure

• Luminance (lux)

• UVA, UVB and UVC irradiance

• Carbon monoxide (CO)

• Carbon dioxide (CO

)

• Solar radiation

• Rainfall quantity

• Wind speed and direction

• Leaf wetness

• Soil volumetric water content

• Level

• WBGT index

The models that measure r elative humidity and temperat u r e calculate h u mi dity derived qu a n tities. Calculated quantities depend on the m odel and can be: dew p oint temp erature, wet bu lb temperature, absolute humidity, mixing ratio, partial vapor pressure.

Data loggers provided with built-in sensors and data loggers with external prob es are available. They can be connected through M12 conn ectors or terminal s accordin g to the m odel. The data loggers with terminal header input can be connected to:

• Transmi tters w ith 0÷20 or 4÷20 mA current output and 0÷50 mV, 0÷1 V or 0÷10 V voltage output (Note: 0÷10 V only for HD35EDWH)

• Pt100 / Pt1000 temperature sensors and K, J, T, N, E thermocouples

• Voltage-free contact output (commutations counting) or potentiometric sensors

This allows the monitoring capability of the system to be extended to many other quantities in addition to the ones mentioned above.

For each detected quantity, the user can set two alarm thresholds (high threshold and low threshold). The alarm hysteresis and del ay can be confi gured for each quantity. The overrun of the thresholds can be indicated by an audible signal of the data logger through an inte rnal buzzer; the alarm signal is immediately transmitted to the base unit and displayed on the PC. A wireless remote alarm module with relay output is available allowing other signaling devices (sirens, flashing lights…) or actuators to be a ctivated. If th e sy stem i s equi pped wi th a G MS/3G module, the alarm can be signaled als o by e -mails or SMS messages.

Systems with the following transmission frequencies are available: 868 MHz (in compliance with ETSI EN 300 220 European Directi ve), 902-928 MHz (in compliance with U.S. FCC part 15 section 247 and I.C. RSS-210 Di rectives) an d 915,9-929,7 MHz (in compliance with ARIB STD-T108 standard).

Thanks to wireless transmission, the installation of the system is a very simple and quick operation. In addi tion, the user wi ll not have to r emove the dat a logger from i ts position or reach the place where the data logger is installed to dow nload the data measured with the PC.

The correctness of the transmitted data is ensured by the bidirectional communication be- tween the base unit and the remote data loggers.

HD35AP-S basi c PC software, d ownloadable free o f charge from th e Delta OHM websi te, allows configuration of all system devices, display of connection status, level of the RF signal and

HD35 - 5 - V1.12

battery charge level, data automatic download at regular intervals or manual download on request of the user. The data transferred to the PC are entered into a database.

Data loggers comply with EN 12830 standard. The optional HD35AP-CFR21 advanced version of the software is desi gned in compliance wi th FDA 21 CFR part 11 recommendations: the operations are protected by access codes and a record of the per formed operations is kept.

HD35 - 6 - V1.12

HD35 - 8 - V1.12

1. INSTALLING HD35AP-S SOFTWARE

Download the HD35AP-S software from the Delta OHM website. Install both HD35AP-S software and MyS QL Data Base Management System (included in the package of HD35AP-S software) in your PC. Concerning the installation of MySQL, thoroughly follow the installation guide contained in the downloaded file.

2. CONNECTING THE BASE UNIT BATTERY (not for HD35APD, HD35APR and HD35AP…GMT)

For shipments by aircraft, the battery of the devices must be disconnected.

1. Unscrew the 4 front screws of the housing and remove the back cover.

2. Attach the battery connector to the electronic board, paying attention to the correct polarity. The connector is equipped with a polarization key that prevents the possibility of a wrong insertion of the connector.

Fig. 3.2: battery in the devices in housing for internal use

3. Close the housing by fixing the 4 front screws.

• Factory-configured system: first connect the battery of the base unit and check the clock setti ng. Only after this operation, connect the battery of the data loggers, so that the clock can be synchronized with the updated clock of the base unit at star tup.

• Not configured system: at startup, data loggers don’t synchronize the clock with that of th e base unit, consequently it is not important to power the base unit as first.

3. CONNECTING HD35AP… BASE UNIT TO YOUR PC

The HD35AP... base unit can be connected to the USB port of a PC through the CP31 cable (directly with USB A-type connect or for HD35APD…). In this connection mode, the base unit is powered through the USB port of the PC.

Fig. 3.3: connecting the base unit to your PC

The USB con necti on doesn’t requir e the inst allati on of driver s: when the bas e unit i s connect ed to the PC, Windows® operating system automatically recognizes the unit as an HID (Human Interface Device) device and uses the drivers already included in the operating system.

Battery

HD35 - 9 - V1.12

Note: even th e ba se u ni ts HD35APW and HD35APR, wi th Wi-Fi and/or Ethernet in terfac e, must first be connected t o the PC vi a USB through t he CP31 cable f or setti ng the pa rameters of the local network (e.g., for setting the IP address, for choosing the Wi-Fi or Ethernet mode, etc.).

4. CONNECT THE SOFTWARE TO THE BASE UNIT

Start the HD35AP-S software in your PC and perform the c onnection procedur e illustrated i n the chapter " Connection to ba se unit " of th e s oft w a re online help.

5. CHECK THE CLOCK SETTING

Select the item " Setting of date and time " of HD35AP-S software and make sure that the clock of the base unit is updated. If the clock is not updated, set it as explained in the chapter " Clock setting " of the software online help.

6. CONNECT THE BATTERY OF THE OTHER NETWORK DEVICES

Connect the b a tt e ry of the other devices followin g t h e p ro ced ure indicated a t step 2 of the p revious page. In the devices with waterproof housing, the posi tion of the battery and the connector is shown in the following figure.

Fig. 3.4: battery in devices with waterproof housing

The models in waterpr oof housi ng with CO

pr obe and the model with RS485 Modbus-RTU in-

put have no internal battery: connect the 7…30 Vdc external power supply.

• Factory-configured syste m: at startup, data loggers synchronize the clock with that of the base unit. If the base unit is not yet connected to the power supply, the synchronization fails and data loggers with LCD option display the clock setting window. Clock synchroni zation will anyway take place automatically after connecti ng the base unit to the power supply. Meanwhile, data loggers start storing measurements with their date and time, not synchronized with respect t o the system mea surements. If you wish t o set the cl ock manually, s ee paragraph The menu in LCD data loggers on page 44.

• Not configured system: at startup, data loggers don’t synchronize the clock wi th that of the base unit. In the data loggers with LCD, the wind ow for the clock setti ng is displayed. Clock synchronization will take place automatically after network configuration (step 8), in the meantime data loggers start storing mea surements w ith th eir date and time. If you wi sh to set the clock manually, see paragraph The menu in LCD data loggers on page 44.

7. ACTIVATING THE RF STAG E IN THE D EV IC E S (DATA LOGGERS, REPEATERS AND ALARM MODULES)

In the devi ces belonging t o a fa ctory-configured system, the RF stage is activated automatically. In this case, proceed to step 9.

If the system is not factory-configured, the RF stage of the devices will have to b e activated manually by pressing the connection button for 5 seconds. In the models in indoor-use housing, the connection button is on the front panel.

Fig. 3.5: connection button in models in indoor-use housing

In models with waterproof housing, the connection button is inside the instrument (see fig.

9.3.1 on page 74).

The activation of the RF stage is signaled by the lightning-up of the green RF LED for one second and by a beep of the buzzer. Successively, the red RF LED will start blinking until the device is added to a wireless network following the procedure indicated at step 8.

In data loggers with LCD display, the activation of the RF stage is signaled also by the connection icon. The icon w ill go on blinking until the d evice is added to a wireless network.

Fig. 3.6: connection icon in the display

In case of doubt of the RF stage status in the devices wit hou t LCD ( f or examp l e, b ecaus e L EDs seldom blink due to a long logging interval), press the connection button for 5 seconds. If the green RF LED lights up, the RF stage was not active and will be activated. If the red RF LED lights up, the RF stage was already active and will be deactivated; in that case, press again the connection button for 5 seconds to reactivate it.

8. ADDING THE DEVIC E S TO THE NETWORK

If the networ k structu re is not configured, it is necessary to add data loggers and any repeaters and alarm mod ul es to t he b as e uni t . The adding procedure, described in detail in the chapter " Adding devices to the network " in the software online help, is briefly outl i ned hereunder:

1. Sel ect th e com m an d " Network " of HD35AP-S software.

2. In the section " Add Devices " of the window " Network ", select the button " Execute search ".

3. At the end of the s earch, the softw are will list th e devices avail able to be added to the network; sel ect the d evi ces, iden tified by the RF ad dress, an d ente r the seri al nu mber of each device ( RF add ress an d seri al nu mber ar e wri tten on the l abel on t he rea r of th e instrument).

4. Select the button " Add to network ".

Note: the procedure for adding th e d evi ces t o th e n et wo rk al l ows a l i mited nu mb er of de vi ce s t o be added at a time.

The table refers to the condition of direct transmission between base unit and data loggers (1 "Hop") in HD35….E (86 8 MHz) and HD35….U (902-928 MHz) systems. In the presenc e of re- peaters, the data t ransm ission requires m ore t ime, an d the nu mber of d evices m anageab le by the base unit could be lower than the one indicated.

9. CHECKING THE QUALITY OF RF COMMUNICATION

The correct RF communicati on between b ase uni t and th e other devi ces connect ed to the network can be checked in the following ways:

• In the main window of the HD35AP-S software, by checking that the RF signal level re- mains high, that the strength of the received signal RSSI (Received Signal Strength Indication) exc eeds -85 dBm and that the percentage of transmission errors PER (Packet Error Rate) is close to zero.

Fig. 3.7: verification of RF communication with HD35AP-S software

• In data loggers with display, by che cking that the strength of the received signal RSSI exceeds -85 dBm and that the percentage of transmission errors PER is close to zero. Use the button

 to display RF RSSI and PER quantities.

• In the devices without display, by briefl y pressing the connection button (PING function) and by making sure that the green RF LED blinks for a few seconds;

10. INSTALLING THE DEVICES

After a bench test of the system, proceed with the individual installation of the devices in the final work location.

If data loggers using external probes with cable are installed, place the probes in the environment to be monitored and connect them to the data loggers (for the connectors layout, see chapters HD35ED… DATA LOGGERS FOR INDOOR USE on page 36 and HD35EDW… WATER- PROOF DATA LOGGERS on page 68).

11. CHECKING WHETHER THE DEVICES ARE REACHABLE

After installing the devices, you need t o veri fy aga in th e corre ct RF commu nica tion b etween the base uni t and t he other devic es of the netw ork, in ord er to make sur e you did n’t pl ace th e d evices too far from th e base uni t or in places t hat make RF transmi ssion dif ficult (shi elded environments or with several obstacles). To check RF communication, proceed as indicated at step 9.

HD35 - 12 - V1.12

12. ADDING REPEATERS TO THE NETWORK

If a device is not reachable after installation (it fails communication with the base unit), it could be n ecessa ry to i nstal l one or more repe aters i n in termedia te poin ts betw een th e devi ce and the base unit.

To add a rep eater to the netw ork, con nect the interna l battery to the r epeater an d repeat the installation procedure from step 7 only for the repeater.

13. CONFIGURING NETWORK PARAMETERS

Through the HD35AP-S software, set all the system operation parameters: logging intervals, alarm thresholds, user codes, etc.

For data loggers, specify whether they are installed in a stationary location or mobile location (for ex. in an articulated vehicle).

See software instructions for the setting of the various parameters.

CHANGING THE RF BAND IN THE …U MODELS

The …U models can operate in the 902-928 (U.S.A. and Canada), 915-928 (Australia) or

921.5-928 (New Zealand) MHz frequency band. To change the band in the devices with LCD, select the RF Frequency item of the RF Parameters menu (models with graphic LCD) or the RF_FREQ_MHZ item o f the RF_MENU menu (models wit h custom LCD). To change the band in the devices without LCD, proceed as follows:

1) If the device is equipped with mini-USB connector on the housing side, connect it to the PC by means of the CP31 cable.

2) Start the HD35AP-S software and select the Tools >> HID terminal command.

3) Select Setup >> Uart configuration.

4) Set the Baud Rate to 9600 for the …ED devices. Set the Baud Rate to 115200 for the …RE and …AP devices. Press Apply.

5) Select Connect.

6) Transmit the command <000>PW;nnnn with nnnn=administrator password.

7) Transmit th e command <000>MC;n with n=1 for the 902-928 MHz band, n=2 for the 915928 MHz band and n=5 for the 921.5-928 MHz band.

8) Select Disconnect.

Note: after the transmission of a command, check that in the reply of the device appears the confirmation symbol &.

HD35 - 13 - V1.12

4 NETWORK MODIFICATION

One or more devices can be added or removed to/from the network at any time.

ADDING A DEVICE TO AN ALREADY OPERATING NETWORK

To add a devi ce to the netw ork, connect t he internal battery to the d evice and rep eat the installation procedure from step 7 concerning only the device to be added.

REMOVING A DEVICE FRO M AN ALREADY OPERATING NETWORK

To remove a d evice from the netw ork, follow the pr ocedure indicat ed in detail in the chap ter " Removing d evic es fro m th e n etw ork " of the s oftwa re online help, and bri efl y des cri bed h ereunder:

1. Select the comman d " Network " of the HD35AP-S software.

2. In the section " Delete Devices " of the window " Network ", select the device that you wish to remove from the network.

3. Select the button " Delete Devices ".

The removal procedure of a devi ce from the netwo rk allows to select whether to turn-o ff the device RF circuit after disconnection or to keep it turned-on so as to allow any connect ion to another network. If the RF circuit is kept turned-on, it turns-off after 30 minutes if in the meantime the device is not connected to another network.

HD35 - 14 - V1.12

5 INSTALLING THE HOUSING FOR INDOOR USE

The installation of models in indoor-use housing can be fixed, by means of anodized-aluminum flanges to be attached to the back of the housing, or removable, by means of a practical plastic support to be fixed to the wall. The use of flanges allows preventing the instrument to be taken away, thanks to the possibility of applying a padlock, inserted in a fa stening pin to be fixed to the wall.

6.4 USB CONNECTION

The base units can be connected to a PC through the mini-USB connector and CP31 cable (directly with type A USB connector for HD35APD). In this connection mode, the base unit is powered through the PC USB port.

Fig. 6.4.1: USB connection

USB connection doesn’t requi re the install ation of driver s: when the b ase uni t is con nected to a PC, Windows® operating system automatically recognizes the unit as an HID device (Human Interface Device) and uses the drivers already included in the operating system.

Note: if the ex te rna l power sup pl y i s not used but only the USB connection, it is recommended to connect the unit to a minimum 500 mA USB port to allow a sufficient recharging of the internal battery (only for models with interna l batte ry).

6.5 ETHERNET OR WI-FI CONNECTION

The HD35APW base uni t can be conn ected to a PC through a n Ethernet or Wi-Fi local network. The choice of the connection mode, Ethernet or Wi-Fi, and of the rel evant settings must be performed with the HD35AP-S software. The HD35APR ba se unit can be connected to a PC through an Ethernet local network

In the connection mode through l ocal network, the HD35APW base unit must be powered by means of the SWD06 external power supply.

HD35 - 20 - V1.12

For the Ethern et mode, connect t he RJ45 connect or of the ba se uni t to a local network socket by means of a standard Ethernet cable.

Fig. 6.5.1: ETHERNET connection

In Wi-Fi mode, connect the base unit to an available Wi-Fi network using the HD35AP-S software (see software instructions).

The base unit connects to the router of th e local netw ork (Wi-Fi Access Point, in Wi-Fi mode) and works a s a client-type device. It is pos sible t o set a fix ed (static) IP address or con figu re the DHCP mode (Dynamic Host Configuration Protocol) so as the unit requests a dynamic IP address to the network server/ rou ter.

Fig. 6.5.2: base unit in Wi-Fi mode operating as a client

It is possible to access the base unit from any PC of the local network where the basic HD35AP-S software was installed (see the connection procedure presented in chapter " Con- nection to base unit " of the software online help).

The connection to the b ase unit is multi-client: the unit has two TCP/IP virtual ports and ten sockets in total to be divided between the two ports. Each port can operate with TCP/IP or MODBUS TCP/IP protocol. The ports setting (port number, number of socket assigned and type of protocol) must be performed with the HD35AP-S software (see software instructions). In MODBUS TCP/IP mode, the base unit works as "Modbus TCP/IP gateway".

HD35 - 21 - V1.12

6.6 RS485 CONNECTION

The HD35APR and HD35APS base units have a RS485 communication port with MOD- BUS-RTU pr otocol . For conn ecti ng the HD35APS base unit, use the CPM12-8D… seri es cabl es

with 8-pol e M12 conn ector. The figure an d the ta ble bel ow show the numbering and the function of the connector contacts:

Thanks to RS485 connection, several instruments can be connected in a multi-point network. The instruments are connected in sequence by means of a shielded cable with twisted pair wires for signals and a third wire for the ground.

Line terminations must be placed at the ends of the network. The cable shield must be connected to both ends of the line.

The maxi m u m n u m ber of devices that c an be conn e cted to th e line (Bu s) R S 485 depend s on the load chara cteristi cs of the d evices to b e connec ted. The RS 485 stand ard require s that th e total load doesn’t exceed 32 (Uni t Loads). Th e l oad o f a ba s e u ni t H D35APR o r HD35APS is equal to 1 unit load. If the total load is higher than 32 unit loads, divide the network in segments and add a signal rep eate r bet ween a segm ent a nd th e f oll owin g. A li ne t ermi nati on m ust be pl aced at b oth ends of each segment.

The cable maximum length depends on the transmission speed and on the cable characteristics. Typically, the maximum length is 1200

m. The data li ne mu st be k ept s eparat ed from an y

power lines to avoid interferences to the transmitted signal.

HD35 - 22 - V1.12

Each instrument in the RS485 network is univocally identified by an addre ss ranging within 1 and 247. No more th an one transmitter wit h the same address can b e present in the same network.

Before connecting the base unit to the RS485 network, configure address and Baud Rate (see chapter " HD35AP… base unit configuration ” of the softwa re online h elp). The communication parameters in the PC/PLC must be the same as those set in the base unit.

6.7 HD35APR CONNECTIONS

RS485 line termination:

If the instrument is at one end of the RS485 li ne, insert the t ermination by pl acing the short jumper next to the RS485 connector between the “RT” and “CLOSE” i ndications. Otherwise, remove the termination by placing the short jumper between the “RT” and “OPEN” indications.

Factory ETHERNET settings:

• IP address = 192.168.1.235 static

• Subnet mask = 255.255.255.0

• Ports = 5100 for proprietary TCP protocol (8 sockets), 502 for Modbus TCP/IP protocol (2

sockets)

The ETHERNET settings can be changed with the HD35AP-S software. It is possible to restore the factory parameters by placing the short jumper next to the NET RST push-button between the “2” and “3” indications and then pressing the NET RST push-button. After the reset, replace the short jumper between the “2” and “1 (NORMAL)” indications.

7.3 DESCRIPTION OF HD35REW IN WATERPROOF HOUSING

1. RF Antenna.

2. BATTERY LED: g reen color, i t indicates the i nternal battery charge level. As t he battery i s

running low, the LED blinks with a lower and lower freq uenc y (t he bl i nk period in crea ses of 1 second for each 10% decrease of the battery charge).

3. ALARM LED: not used.

4. Red RF LED: it blinks to signal that data transmission has failed.

5. Green RF LED: it blinks if the data transmission was successful.

The green and red RF LEDs blink simultaneously if the device is in error co ndition.

7.4 CONNECTION TO THE WIRELESS NETWO RK

The device can be connect ed and discon nected to/fr om the wirel ess network b y pressing f or 5 seconds:

o the connection button on the front panel, for HD35RE (see point 6 of paragraph 7.1); o the internal connectio n button, for HD35REW (see the following figure).

Fig. 7.4.1: HD35REW internal connection button

Connection button

HD35 - 33 - V1.12

sion. If the device doesn’t belong to a wireless network or the base unit cannot be reached, the second beep of the buzzer is not emitted and the red RF LED will blink.

If the device is connected, by pressing the connection button for 5 seconds the buzzer emits a beep, the red RF LED activates for one second and the device is disconnected.

PING function:

In the devices connected to a wireless network it is possible to check if the base unit can be reached by briefly pressing the connection button: if the gr een RF LED is blinking, it means that the base unit is reachable, otherwise it will be the red RF LED to blink.

7.5 ARRANGEMENT OF THE REPEATERS

Designing the sy st em it should be taken into account that between a HD35REW repeater and a HD35ED... da ta logger or b etween two HD 35REW repeat ers, only HD 35REW repeat ers can be interposed, as shown in following examples.

Fig. 7.5.1: arrangement of different types of repeaters

Unlike HD35RE repeaters, which have external power supply, the HD35REW repeaters are powered only by the internal battery. To extend the battery life, the RF stage of the HD35REW repeaters i s not cont inuous ly acti ve; th erefore, the HD35R EW rep eaters are subj ect to th e following restrictions:

o the alarm events may be reported with a certain delay; o the addin g of new devi ces to the wireless network mu st be don e near the HD35AP.. b ase

unit, without interposing HD35REW repeaters between the new devices and the base unit;

o the reconfi guration of th e system may take longer; furtherm ore, if the con figuration of a

data logger with LCD is changed via the logger keyboard, the change is not notified to the base unit and to the HD35AP-S software;

o to guarantee the same transmission reliability of a system with HD35RE repeaters,

HD35ED… devices may be obliged to transmit the same packets several times: this could affect battery life.

Data logger models in indoor-use housing

In order to highlight the physical quantities measured by data loggers, order codes include some identification c haracters for the var io us quantities, according to the following convention:

1 = Humidity

4b = Atmospheric pressure (barometer)

4 = Diff er ential pressure (4r1 = ran ge 1, 4r2 = ran ge 2, etc. )

N = Temperature with NTC10K sensor (N/1 = 1 channel, N/2 = 2 channels, N/3 = 3 channels)

7P = Tempera ture with Pt 100/Pt10 00 sensor (7P/1 = 1 channel, 7P/2 = 2 channels, 7P/3 = 3 channels)

A = Carbon monoxide (CO)

B = Carbon dioxide (CO

)

I = Illuminance low range (0...20,000 lux), I2 = Illuminance high range (0...200,000 lux)

U = UV irradiance (U=UVA, UB=UVB, UC=UVC)

TC = Probe with cable TV (or TVI) = Fixed vertical probe without cable TCV = Probe with cable + fixed vertical probe without cable

Models measuring temperature and humidity with a combine d probe with cable (…TC models) use the probes of the HP3517… series (with NTC 10KΩ @ 25 °C or Pt100 temperature sensor according to the model). Replacement of the HP3517… probe requires recalibration of the in- strument i n line with the new probe .

In models with 2 or 3 M12 connectors, the input number is indicated above the connecto r. In models for the measurement of the atmospheric pressure, the sensor is inside the instrument. In models for the measurement of the differential pressure, please pay attention to the polarity

indicated next to conn ections.

seconds the connection button on the front panel (see point 6 of paragraph 8.1).

If the device is disconnected, by pressing the connection button for 5 secon ds the buzzer emits a beep and the green RF LED blinks for one second to indicate the sta rt of the connection procedure. If th e device bel ongs to a wirel ess network and the base uni t is reachable, once connected, the buzzer emits a second beep and the green RF LED will blink during data transmission. If the device doesn’t belong to a wireless network or the base unit cannot be reached, the second beep of the buzzer is not emitted and the red RF LED will blink.

If the device is connected, by pressing the connection button for 5 seconds the buzzer emits a beep, the red RF LED activates for one second and the device is disconnected.

In data loggers with LCD display, the connection status is signaled al so by the connection icon on the display (see figure 3.6 at page 10):

• the icon is steady on if the data logger is connected;

• the icon blinks if the data logger is trying to connect (the icon will be steady on once

connected or will go on blinking if the base unit is not reachable o the data logger doesn’t belong to a wireless network);

• if the data logger is not connected, the icon has the aspect of a hang up phone i n data loggers with graphic LCD, and it is off in data loggers wit custom LCD.

PING function: In the devi ces connected to a wireless network it is possible to check if the base unit can be

reached by briefly pressing the connection button: if the gre en RF LED is blinki ng, it means that the base unit is reachable, otherwise it will be the red RF LED to blink.

8.3 DATA LOGGERS WITH LCD OPTION

According to the data logger model, the LCD display is custom (L option) or graphic (G option) type. The display shows all quantities measured and calculated by the data logger along with the following RF quantities:

• RSSI (Received Signal Strength Indication): received signal power;

• PER (Packet Error Rate): percentage of transmission errors;

• RF Hops: 1=direct transmission between data logger and base unit, 2= a repeater

added between data logger and base unit, 3=two repeaters added, etc.

The indications of connection status, logging (in progress/deactivated), and battery charge level are displayed.

Fig. 8.3.1: custom LCD

In models with custom LCD that measure several quantities, the temperature is displayed in the secondary line, except when a RF quantity appears in the main line; i n that case the secondary line shows the number of RF hops.

Models with graphic LCD allow the simultaneous display of 3 measurements in the secondary lines. The graphic display shows in addition the RF signal level and date & time.

8.6 CALIBRATION

Instruments and sensors are all factory-calibrated and do not normally require further interventions of the user. Anyway, a new sensor calibration can be performed for:

o CO at zero ppm, o CO

at any reference value within the measurement range,

o R.H. at 75% and 33%, o Differential pressure at zero.

No calibration is scheduled for temperature sensors. For a correct calibration of the probes, it is crucial to know and respect the physical phenome-

na which u nderlie meas urements: for this r eason, it i s recommend ed to thoroug hly foll ow the following instructions and to perform new calibrati ons only if in possession of adequate technical knowledge and instruments.

To access calibration, the data logger must have the user-calibration option set:

o In models w it h gr a p h ic L C D , s e le c t t he menu item Calibration

⇒

Calibration Type and set t he

User option.

o In models wi t h cu st om LC D, sel ect t h e m enu i tem CAL_MENU

⇒

option.

The calibration procedure deletes the data of the previous user calibration. In case of failed procedure, you can always return the instrument to factory calibration by selecting:

o in models with graphic LCD, the menu item Calibration

⇒

Factory option;

o in models wi th custom LCD, the menu item CAL_MENU

⇒

to operate in a stable environment.

8.6.4 CO

SENSOR AUTOCALIBRATION

In HD35ED[G]…B models, t he i nstrum ent ca n be s et so a s CO2 calibration is automatically performed at predetermined intervals.

In order fo r auto calibrati on to be effecti ve, the CO

concentration in the envi ronment where the instrument is installed must assume a known value (referred to as environment back- ground value). For example, we can have that an instrument installed inside a public place performs a we ekly auto calibrati on wh en peopl e are n ot pre sent an d C O

concentration is cl ose

to the outdoor air value (if there is an adequate air change).

Fig. 8.6.3: exam ple of background value for CO

auto calibration

The offset applied to the measurement by the auto calibration procedure can be limited to a maximum value, so as to avoid erroneous calibrations when the measured value differs too much from the estimated background value. The auto calibration procedure acts therefore in the followin g w a y :

o If the difference between the measured value and the background value is lower than the

maximum offset, an offset is a pplied to t he measu rement so th at the m easured val ue coincides with the background value.

o If the difference between the measured value and the background value is higher than the

maximum offset, only the maximum offset is added or subtracted so as to approach the background value.

To set the auto calibration interval and the maximum offset and to activate auto calibration see the menu item CO

8.6.5 CALIBRATING THE RELATIVE HUMIDITY SENSOR

The sensor can be calibrated in the t wo p oin ts 7 5%RH and 33%RH. Before starting the calibration procedure, it’s better to check if a new cal ibration is nec essary, wi th the aid of 75.4%RH and 33%RH saturated solutions (except HD35ED [G]1… B mod el s, that req uire a cl ima tic ch amber): a cal ibrati on wil l be p erform ed on ly i f an er ror of a few hu midi ty poi nts i n one of t he two calibration points is detected.

The sensor can be calibrated in both points or in one point only.

Preliminary operations before calibration:

Check that the chamber with the saturated saline solutions contains at the same time:

• solid state salt,

• liquid s olution or wet sa lt , in pa rticular for th e 75 %RH solution. The instrument and the saturated solutions to be used for this operation must be placed in a

stable te mperature envi ronment for th e whole calib ration period. W ait for at least a couple of hours with a stable temperature so that the instrument and the saturated solutions reach a thermal b alance with th e envi ronmen t befo re sta rting t he cal ibrati on proced ure. In orde r to obtain a go od cal ibrat ion, i t is c rucia l that the p robe and th e sol uti on have the same t emp erature. Bear in mind that plastic material is a bad heat conductor.

Calibration should be performed at a temperature ranging within 15 and 30°C.

Calibrati o n pr oce dur e:

1. Unscrew the probe protection grid and screw the M12×1 threaded ring.

Avoid any contact of the sen sitive element w ith your hands o r other objects or liquids. If some liquid has f ormed inside th e measuring cham ber, dry it wi th a clean absorbent paper towel.

2. Unsc rew the cap of the saturat ed solution. S crew the thr eaded ring wi th the probe on the

saturated solution container and wait for at least 30 minutes.

3. A ccess the men u with the adm inistrator pa ssword and s elect the item CAL_MENU (custom

LCD) or Calibration (graphic LCD). Press ENTER to confirm.

4. Select the i tem RH_75%_CAL (custom LCD) or RH 75% calibration (g raphic LCD) t o calibrate

the point 7 5%RH; select the item RH_33%_CAL (custom LCD) or RH 33% calibration (graphic LCD) to calibrat e t he po int 33% RH . Pre ss ENTER to confirm.

5. In the models with custom LCD, the blinking value of t he saturated sol ution at the tem-

perature mea sured by the prob e is displayed. In the model s with graphic LCD, the value measured by the instrument (on the left) and the calibration point (on the r ight) appear.

One sample consists of all the quantities measured and calculated by the data logger at the same instant of acquisition. For example, the model HD35ED1NAB measures four quantities and ca lculates five quantities (the derived humidity qua ntities) and one sample includes on e temperature measure, on e CO measure, one CO

measure and six humidity measures (the relative humidity measure plus

the five derived

quantities).

Data logger models in waterproof housing

In order to highlight the physical quantities measured by data loggers, order codes include some identification characters for the various quantities, according to the following convention:

1 = Humidity

4b = Atmospheric Pressure (barometer)

N = Temperature with NTC10K sensor (N/1 = 1 channel, N/2 = 2 channels, N/3 = 3 channels)

7P = Tempera ture with Pt 100/Pt10 00 sensor (7P/1 = 1 channel, 7P/2 = 2 channels, 7P/3 = 3 channels)

K = Temperature w ith thermocouple sensor (K/4 = 4 channels)

R = Solar radiation (pyranometer)

I = Illuminance low range (0...20,000 lu x ) , I2 = Illuminance high range ( 0...200,000 lux)

F = PAR (Photosynthetically Active Radiation )

P = Rainfall quantity

L = Leaf wetness

S = Soil v olumetric water content

B = Carbon dioxide (CO2) range 0…5,000 ppm B2 = Ca r b on dioxide (CO2) range 0…10,000 ppm

TC = Probe with cable TV (or TVI) = Fixed vertical probe without cable TCV = Probe with cable + fixed vertical probe without cable

In models with 2 or 3 M12 connectors, the input number is shown on the connector side. In models measuring the atmospheric pressure, the sensor is inside the instrument.

9.2 INSTALLATION OF WATERPROOF HOUSING

The housing for waterproof models can be fixed to a wall or, for outdoor installations, to a 40 mm diameter mast by means of HD2003.77/40 clamping (for hous ing H=1 20 mm x L=8 0 mm).

Fig. 9.2.1: installation of waterproof housing

For outdoor i nstallations, use the optional protection shield against solar radiations (for hous-

ing H=120 mm x L=80 mm).

Data loggers supplied with clamping already mounted on the back of the housing are equipped with protect ion devices again st over-voltages connected to the clamping. For a correct operation of the prot ecting devices, th e yellow/green w ire with fast-on connector connected to the clamping should be connected to ground.

The outdoor installation of the combined temperature and relative humidity probe requires

HD9007A-1 or HD9007A-2 protection against solar radiations.

9.3 CONNECTION TO THE WIRELESS NE TW OR K The device c an be connect ed and disc onnected to/f rom the wirel ess n etwork by pressing for

5 seconds the internal connection button (CONNECT/DISCONNECT button).

9.9 WBGT INDEX MEASUREMEN T

HD35EDWWBGT can contemporarily detect the following quantities:

• Globe thermometer temperature Tg

• Natural ventilation wet bulb temperature Tnw

• Ambient temperature Ta

On the basis of the detected measurements, the instrument can calculate:

• WBGT

indoor

index: WBGT index in absence of solar irradiation.

WBGT

indoor

= 0.7 Tnw + 0.3 Tg

• WBGT

outdoor

index: WBGT index in presence of solar irradiation.

WBGT

outdoor

= 0.7 Tnw + 0.2 Tg + 0.1 Ta

The WBGT (Wet Bulb Globe Temperature) index is one of the indexes used for determining the thermal stress to w hich an individual is submitted to in a warm envi ronment. For W BGT in dex measurement, refer to ISO 7243 standard.

To calculate WBGT index according to ISO 7243 standard, it’s necessary that to the instrument are connected:

• TP3501TC2 or TP3204 natural ventilation wet bulb temperature probe.

• TP3576TC2 or TP3575TC2 globe thermometer.

• TP3507TC2 dry bulb tempe rature probe i f the detection is made in presen ce of solar

irradiation.

Preparation of the TP3576TC2 or TP3575TC2 globe thermometer:

Preparation of the TP3501TC2 wet bulb temperature probe:

1. Remove the cover (the cover is not screwed).

2. Ins ert the cotton wi ck, previously dipped with distilled water, into the temperatur e probe.

The cotton wi ck must protrude from the probe for about 20 mm.

3. Fill the container up till ¾ with distilled wate r .

4. Close the container with the cover.

HD35 - 81 - V1.12

Warning: don't turn the probe from the vertical direction because the distilled water can exit. The cotton wick calcifies (becomes hard) with time: replace it periodically.

Preparation of the TP3204 wet bulb temperature probe:

1. Remove the sensor cap (the cap is not screwed).

2. Ins ert the cotton wi ck, previously dipped with distilled water, into the temperatur e probe.

The cotton wi ck must protrude from the probe for about 20 mm.

3. Replace the cap.

4. Fill the bottle with 500 cc of distilled water.

5. Turn the probe over and firmly screw the bottle to the probe reservoir.

6. Turn the probe quickly (to avoid water spillage).

7. Sec ure th e prob e to th e HD32.2.7.1 support by using the two screws at the bottom of the

probe.

For measurements in presence of solar irradiation, use the protection shield from solar radiations. The cotton wick calcifies (becomes hard) with time: replace it periodically.

2. Connection button.

3. External RF Antenna (optional). The antenna is internal by default. On request, the antenna

can be external fixed or with 3 m cable.

4. Bicolor RF LED: blinks green if data transmission was successful; blinks red to indicate that data transmission has failed.

5. Custom LCD display (optional).

HD35 - 92 - V1.12

10.2 MEASURING PROBES

Relative humidity and temperature: Models measuring temperature only (option N) use

the probe TP350NTC2 with NTC 10KΩ @ 25 °C sensor. Models measu ring relative hu midity and temp erature (option 1N) use the combined probe

HP3517TC2 with NTC 10KΩ @ 25 °C temp erature s ensor. Al ternativel y, to the same i nput can be connected the temperature only probe TP350NTC2.

The outdoor install ation of th e prob e requi res HD9007A-1 or HD9007A-2 protection against

solar radiations. Replacement of the probe requ ires recalibration of the instrument

in line with the new probe. Atmospheric pressure: The sensor is inside the instrument. Rainfall qu antity: For models measuring rainfall quantity (option P), the rain gauges HD2013

(area 400 cm

), HD2013R (area 400 cm2, with heating), HD2015 (area 200 cm2) and

HD2015R (area 200 cm

, with heating) are available.

Solar radiat ion: To th e models provided with input for the solar radiation sensor (option R),

the pyranometers LP PYRA 02, LP PYRA 03, LP SILICON-PYRA 04, etc. with mV output signal

can be connected. In addition to the solar radiation in W/m

, the inst rument also records

the pyranometer output signal in mV.

Wind speed and direction: Models measuring wind speed (option W) and direction (option

D) use the cup anemometer HD54.3 and the wind vane HD54.D.

The cup anemometr and the win d vane require a minimum threshold speed (typically 1÷1.5

m/s) to provide reli abl e indi cations. If the sp eed fall s b elow th e minim um thresh old , th e direc-

tion indication is frozen at the last value measured, while the speed indication is blocked to the

threshold value or to zero (the behaviour is configurable by using the HD35AP-S software).

10.3 INSTALLATION OF HOUSING

The housing can be fixed to a wall or, for outdoor installations, to a 40 mm diameter mast by means of HD2003.77/40 clamping.

Fig. 10.3.1: installation of housing

For outdoor installations, use the optional protection shield against solar radiations. Data loggers supplied with clamping already mounted on the back of the housing are equipped

with protect ion devices again st over-voltages connected to the clamping. For a correct operation of the prot ecting devices, t he yellow/gree n wire with fast-on connector connected to the clamping should be connected to ground.

The outdoor installation of the combined temperature and relative humidity probe requires

HD9007A-1 or HD9007A-2 protection against solar radiations.

10.4 CONNECTION TO THE WIRELESS NETWORK The device c an be connect ed and disc onnected to/f rom the wirel ess n etwork by pressing for

5 seconds the connection button.

If the device is di sconn ected , by pressing for 5 seconds the connection button the buzze r emi ts a beep and the RF LED blinks green for 1 second to i ndicate the start of th e connecti on procedure. If the device belongs to a wireless network and the base unit is reachable, after connection the buzzer emits a second beep and the RF LED blinks green during data transmission. If the device doesn ’t b el on g t o a wi rel ess n etw ork a nd th e b a se u ni t i s n ot r ea ch abl e, t h e se c ond b e ep of the buzzer is not emitted and the RF LED will blink red.

If the device i s connected, by pressing for 5 seconds the connection button the buzzer em it s a beep, the RF LED blinks red for 1 second and the device is disconnected.

The connection status is signaled also by the connection icon on the display (see figure 3.6 on page 10):

• the icon is steady on if the data logger is connected;

• the icon blinks if the data logger is trying to connect (the icon will be steady on after

connection or will go on bl inking if the base unit cannot be reached or the data logger doesn’t belong to a wireless network);

• the icon is off if the data logger is not connected.

11 HD35ED-ALM REMOTE ALARM DEVICE

11.1 DESCRIPTION

1. ALARM LED: red color, it blinks to signal alarm conditions.

2. BATTERY LED: green color, it indicates the internal battery charge level. As the battery

runs low, the LED blinks with a lower and lower frequency (the blink period in creases o f 1 second for each 10% decrease of the battery charge).

3. Relay outputs. The connection terminals are protected by a cover.

4. Green RF LED: it blinks if RF transmission was successful.

5. Red RF LED: it blinks to indicate that RF transmission has failed

6. Connection / PING (for testing RF) button.

7. Internal RF antenna.

11.2 CONNECTION

Two bistable relays with potential-free contact a re avai l abl e. In o rd er f or rel ays t o b e act i vated in case of an alarm, alarm conditions should be associated to relays activation through the HD35AP-S software (see section Alarm settings in the software instructions). Contacts arrangement is shown in the following figure.

12 MODBUS

In MODBUS communication the base unit works as a multiplexer (i.e., as an interface) to address MODBUS commands from PC/PLC to wireless network devices. That means that the address of a wireless device (for ex. a data logger) which is not physically connected to the RS485 (MODBUS-RTU) or LAN (MODBUS T CP/IP) network can b e added to the M ODBUS co mmand: t he base unit, physically connected to the RS485 o r LAN network, will intercept the command and will send it to the interested wireless device. The wireless device will execute the comman d and reply to the base unit; this will send back the reply to th e PC/PLC. In order for a wireless device to be addressed successfully, devices with the same MODBUS address as that of wireless devices should not be prese nt in RS 485 or LAN network.

The device general information can be read through the function code 0x2B/0x0E. It consists of:

• Manufacturer (Delta OHM)

• Model

• Firmware version

The compl ete list of MODBUS regis ters is sh own bel ow. Acc ording t o the dev ice mod el, som e of the listed register s could not be p resent if not sig nificant for that p articul ar model (for ex. , CO

measurem ent wil l not b e avai labl e if it i s not mea sured b y the data logg er). If you t ry to r ead a register th at is not pr esent, the i nstrument r eturns the fi xed value 32767. In case of doubt on the registers actually available in a particular model, use the function " Download the list of MODBUS registers of the device " included in the Settings sections of HD35AP-S soft ware (see software instructions).

The following conventions have been used in the tables: o AP = base unit, ED = data logger, RE = re peater, AL = alarm module

AP, ED, RE, AL columns indicate the device where the parameter is available.

o Type: b = bit, B = 8 bits (Byte), W = 16 bits without sign (Word), SW = 16 bits with sign o (x10) = decimal value expressed a s an integer ( e.g., if the c ontent of the register is 1 84,

the value is to be intended as 18,4). o (x100) = centesimal value expressed as an integer (e.g., if the content of the register is

500, the value is to be intended as 5,00). The commands for requesting units of measu rement return an i ndex according to the corre-

spondence indicated in the table below:
