1INTRODUCTION

The Delta OHM wireless data logging system allows several physical quantities to be monitored

in a large variety of application fields. Data loggers are available for the monitoring of:

•Temperature

•Humidity

•Atmospheric pressure

•Differential pressure

•Luminance (lux)

•UVA, UVB and UVC irradiance

•Carbon monoxide (CO)

•Carbon dioxide (CO2)

•Solar radiation

•Rainfall quantity

•Wind speed and direction

•Leaf wetness

•Soil volumetric water content

•Level

•WBGT index

The models that measure relative humidity and temperature calculate humidity derived quanti-

ties. Calculated quantities depend on the model and can be: dew point temperature, wet bulb

temperature, absolute humidity, mixing ratio, partial vapor pressure.

Data loggers provided with built-in sensors and data loggers with external probes are availa-

ble. They can be connected through M12 connectors or terminals according to the model. The

data loggers with terminal header input can be connected to:

•Transmitters with 0÷20 or 4÷20 mA current output and 0÷50 mV, 0÷1 V or 0÷10 V volt-

age 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 thresh-

old). The alarm hysteresis and delay can be configured for each quantity. The overrun of the

thresholds can be indicated by an audible signal of the data logger through an internal buzzer; the

alarm signal is immediately transmitted to the base unit and displayed on the PC. A wireless re-

mote alarm module with relay output is available allowing other signaling devices (sirens, flashing

lights…) or actuators to be activated. If the system is equipped with a GMS/3G module, the alarm

can be signaled also by e-mails or SMS messages.

Systems with the following transmission frequencies are available: 868 MHz (in compliance

with ETSI EN 300 220 European Directive), 902-928 MHz (in compliance with U.S. FCC part

15 section 247 and I.C. RSS-210 Directives) and 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 oper-

ation. In addition, the user will not have to remove the data logger from its position or reach

the place where the data logger is installed to download 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 basic PC software, downloadable free of charge from the Delta OHM website, al-

lows 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 re-

quest 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 ver-

sion of the software is designed in compliance with FDA 21 CFR part 11 recommendations:

the operations are protected by access codes and a record of the performed operations is kept.

HD35 -6-V1.12

2SYSTEM COMPONENTS

The system consists of the following components:

•HD35AP… base unit

•HD35RE… repeaters

•HD35ED… series of data loggers

•HD35ED-ALM remote alarm device

HD35AP… BASE UNIT

This device acts as an interface between the network data loggers that are positioned in the

measurement sites, and the PC. It communicates wireless with the remote data loggers.

Fig. 2.1: base unit placed between data loggers and PC

HD35RE… REPEATERS

These devices are able to act as a bridge between the base unit HD35AP… and the remote data

loggers HD35ED…, allowing the communication distance between data loggers and base unit to

be increased. Several repeaters in cascade can be used.

Fig. 2.2: repeater placed between data loggers and base unit

HD35ED… DATA LOGGERS

Remote devices with measurement probes. They are installed in the locations to be monitored.

They acquire measurements, store them in the internal memory and send them automatically

to the base unit at regular intervals or on request of the user. Versions with or without LCD

display are available.

HD35ED-ALM REMOTE ALARM DEVICE

3INSTALLING THE SYSTEM

Before placing the devices in the final working environment, it is recommended to perform the

system function test on the bench. The bench test allows also the wireless network to be con-

figured more easily, in case the supplied system is not factory-configured.

To check and make the system operational, proceed as follows:

Fig. 3.1: system installation procedure

1. Install HD35AP-S and MySQL softwares

2. Connect the battery to the base unit

3. Connect the base unit to the PC

4. Connect the software to the base unit

8. Add devices to the network

9. Check RF communication quality

11. Check if the devices can be reached

All devices can be reached

Some devices cannot be reached

12. Add repeaters to the network

Installation Completed

13.Configure network parameters

5. Check the clock setting

6. Connect the battery of the other network devices

HD35 -8-V1.12

1. INSTALLING HD35AP-S SOFTWARE

Download the HD35AP-S software from the Delta OHM website. Install both HD35AP-S soft-

ware and MySQL Data Base Management System (included in the package of HD35AP-S soft-

ware) 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 po-

larity. 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 setting. 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 startup.

•Not configured system: at startup, data loggers don’t synchronize the clock with that of the

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 connector 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 connection doesn’t require the installation of drivers: when the base unit is connected

to the PC, Windows® operating system automatically recognizes the unit as an HID (Human In-

terface Device) device and uses the drivers already included in the operating system.

HD35 -9-V1.12

Note: even the base units HD35APW and HD35APR, with Wi-Fi and/or Ethernet interface, must

first be connected to the PC via USB through the CP31 cable for setting the parameters 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 connection procedure illustrated in

the chapter " Connection to base unit " of the software 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 battery of the other devices following the procedure indicated at step 2 of the pre-

vious page. In the devices with waterproof housing, the position of the battery and the con-

nector is shown in the following figure.

Fig. 3.4: battery in devices with waterproof housing

The models in waterproof housing with CO2probe and the model with RS485 Modbus-RTU in-

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

•Factory-configured system: 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 synchronization will

anyway take place automatically after connecting the base unit to the power supply. Mean-

while, data loggers start storing measurements with their date and time, not synchronized

with respect to the system measurements. If you wish to set the clock manually, see para-

graph The menu in LCD data loggers on page 44.

•Not configured system: at startup, data loggers don’t synchronize the clock with that of

the base unit. In the data loggers with LCD, the window for the clock setting is displayed.

Clock synchronization will take place automatically after network configuration (step 8), in

the meantime data loggers start storing measurements with their date and time. If you wish

to set the clock manually, see paragraph The menu in LCD data loggers on page 44.

7. ACTIVATING THE RF STAGE IN THE DEVICES (DATA LOGGERS,REPEATERS AND ALARM MODULES)

In the devices belonging to a factory-configured system, the RF stage is activated automatical-

ly. In this case, proceed to step 9.

If the system is not factory-configured, the RF stage of the devices will have to be activated

manually by pressing the connection button for 5 seconds. In the models in indoor-use hous-

ing, 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 sec-

ond and by a beep of the buzzer. Successively, the red RF LED will start blinking until the de-

vice 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 connec-

tion icon. The icon will go on blinking until the device 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 without LCD (for example, because LEDs

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 DEVICES TO THE NETWORK

If the network structure is not configured, it is necessary to add data loggers and any repeat-

ers and alarm modules to the base unit. The adding procedure, described in detail in the chap-

ter " Adding devices to the network " in the software online help, is briefly outlined hereunder:

1. Select the command " 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 search, the software will list the devices available to be added to the

network; select the devices, identified by the RF address, and enter the serial number of

each device (RF address and serial number are written on the label on the rear of the in-

strument).

4. Select the button " Add to network ".

Note: the procedure for adding the devices to the network allows a limited number of devices to

be added at a time. If the software doesn’t list all the devices to be added, complete in any case

the procedure with the listed devices and repeat the procedure to add the missing devices. By

repeating the procedure, the software will list only the devices that have not been added yet.

Note: during the procedure, keep a distance of at least 2 meters between devices and base unit,

in order to avoid RF signal saturation.
