3 Safety information Read these operating instructions before using the DuoSens for the first time!
Become completely familiar with the installation and operation of the DuoSens and its accessories. Note all the additional information on dangers given within the individual work
steps. Only use the DuoSens and it's accessories in the manner described in these
operating instructions. Make sure that the point of installation is sufficiently protected against moisture
(protection type IP 30)! Select the point of installation such that the ambient temperature never goes
outside the allowable temperature range of –40 °C … +70 °C! Do not open DuoSens! The connection of sensors, communication devices,
power supply, switching contacts or additional components is only carried out via the screw terminal strips/9-pin Sub-D plug connectors accessible from the outside. Before connecting the power supply, check whether the wiring of all wires
attached to the screw terminal strip has been correctly carried out. It is essential to comply with the electrical limits given in the "Technical Data"
section. Only connect the DuoSens to a power supply with lower than 28 V direct
current. Always use a galvanically separated safety low voltage for the mains supply. Do not make any changes or additions to the DuoSens. Have a defective DuoSens checked and repaired by the OTT repair centre.
Never make any repairs by yourself under any circumstances.
Caution: With a complete full data memory in the DuoSens, after an interuption of the operating voltage it can take a few minutes until communication is possible again.

5 Introduction The DuoSens is a datalogger especially conceived for hydrometry, meterology and environmental measuring technology. In the basic version there are four physical input channels. The standard version of the DuoSens also has an LCD display and a jog shuttle. (The jog shuttle is a special operating button that can be turned and pressed.) On request, the DuoSens is available with analog and/or RS-232 expansion. In the database of the DuoSens, 30 logical channels (+ 1 info channel) can be stored. Plug-in screw terminal strips allow simple connection of sensors and the power supply without having to open the device. An LED on the front shows the various operating states of the datalogger. Configuration and parametrization are carried out using the "LogoSens/DuoSens operating program" PC software. This software allows one to comfortably and flexibly tailor to a wide range of measurement requirements. All inputs are equipped with an integrated overvoltage protection. The very low power consumption makes it possible to operate with solar power without problem. Together with a GSM modem (mobile radio modem), remote data transfer and remote parameter input is possible via the GSM cell phone network (GSM = global system for mobile communications). The remote data transfer can be optionally carried out via a dial-up telephone connection, by SMS text messages or using the packet oriented mobile radio transmission service GPRS (general packet radio service). In the same way, remote data transfer is also possible using a satellite transmitter or a grid bound modem. Furthermore, the DuoSens also has individually configurable alarm management: If particular events arise, the DuoSens generates an alarm independently and sends this via a modem, for example, to a control center. It is also possible to control external devices via potential-free contact outputs.

8 Establish communication connection between PC and DuoSens In Chapters 9 and 11 to 18 the establishment of a communication connection between the DuoSens and a PC is a pre-requisite for the following steps. The following description illustrates the setup of this communication link and its variations. Hardware and software requirements: current standard PC with RS-232 interface or USB interface (desktop/tower or notebook design). Operating system: from Windows 2000 (SP4). Additional (accessories): OTT IrDA-Link USB reading head or OTT Duolink reading head 1) or Data transfer line DuoSens/PC 1)
with PCB version b; see label on the connection line
The communication between the DuoSens and a PC is made with the OTT IrDALink USB / OTT DuoLink reading head non-contact with invisible infrared light (IrDA interface). Setting up a communication link with an OTT IrDA-Link USB reading head Connect the OTT IrDA-Link USB reading head to a USB interface on the PC. (USB interface drivers must be installed – see separate installation instructions.) Place the OTT IrDA-Link USB reading head on the DuoSens infrared interface (see Fig. 2). Start the DuoSens/LogoSens operating program. Select the communication path IrDA – OTT IrDA-Link in the DuoSens/LogoSens operating program. Set up a communication link with an OTT Duolink reading head as follows Connect the OTT Duolink optical reading head to a serial PC interface (COM1/COM2). Direct the OTT DuoLink reading head at the DuoSens infrared interface (see Fig. 2). Start the DuoSens/LogoSens operating program. In the DuoSens/LogoSens operating program, select the communication path IrDA – OTT DuoLink and the serial interface used (COM1/COM2). Set up a communication link with a data transfer line as follows Connect data transfer line (9-pin Sub-D socket to 9-pin Sub-D socket; PIN 2 and PIN 3 each crossed) to a serial interface of the PC (COM 1/COM 2). Connect data transfer line to the serial communication interface of the DuoSens (COM 1). Start the DuoSens/LogoSens operating program. In the DuoSens/LogoSens operating program, select the communication path RS-232/V.24 and the serial interface used (COM1/COM2).
20
Note Change the language of the DuoSens/LogoSens operating program if necessary:
Press the F3 function key (repeatedly) until the desired language appears.
The infrared interface of the DuoSens has a radiation angle of approx. ±15 °. The integrated infrared interface of a PC (standard for many notebooks) can
only be used with the Windows 95 and Windows NT operating systems!
Caution: With a complete full data memory in the DuoSens, after an interuption of the operating voltage it can take a few minutes until communication is possible again.
21
9 Adjusting DuoSens operating parameters To set the DuoSens operating parameters you need the PC software DuoSens/LogoSens operating program (WBSLA0.exe). This software is contained on the CD-ROM DuoSens software (accessory). Hardware and software requirements: current standard PC with RS-232 interface or USB interface (desktop/tower or notebook design). Operating system: from Windows 2000 (SP4).
9.1 Install DuoSens/LogoSens operating program Install the DuoSens/LogoSens operating program as follows Insert CD-ROM ➝ Start | Execute I d:\Software\English\setup.exe (d = CD-ROM drive; alternative: \Deutsch\ or \Français\ or \Español\ for other languages). Follow the installation instructions on the screen.
9.2 Adjusting DuoSens operating parameters Adjust the DuoSens operating parameters using a PC as follows Set up the PC/DuoSens communication link (see Chapter 8). If you have not already done so: Connect DuoSens to operating voltage. After a few seconds, the DuoSens is ready to use (DuoSens basic: LED on the front blinks and then goes out; DuoSens standard: LCD display shows various messages and then goes out). Start the DuoSens/LogoSens operating program. Select the Device Function DuoSens menu.
Fig. 20: Start window of the software "DuoSens/LogoSens operating program".
22
Select the Device Function DuoSens menu. Select the function "New configuration" in the "File" menu.
Fig. 21: Creating a new channel
The DuoSens is configured by creating logical channels. Each channel is visible in a tree diagram on the left side of the window. You can easily drag channel functions from the function list to the "tree" with "drag & drop". For example, to create a new channel, drag the "new channel" function block in the "channel" register to the white area of the tree diagram. Caution. Please observe the following rules when creating a configuration: Assign each channel number only once. Follow this configuration sequence: "Measurement cycle" * ➝ "Measurement module" * ➝ "Processing" ➝ "Instantaneous value" ➝ "Limit" ➝ "Save" * * this function block is compulsory. If the "Instantaneous value" function block is missing, the instantaneous values are not shown in the LCD display (DuoSens standard version) and in the "Instantaneous values" function of the operating program (DuoSens basic version). End each channel with "Store". Changing a configuration will delete the measurement memory! Configure each DuoSens independently. Use the functions "Configuration", "Load" and "Store" to save the configuration and to transfer it to other DuoSens units. Caution: The DuoSens processes the individual function blocks in the tree diagram sequentially from top to bottom! It is in principle impossible to execute more than one function at the same time. It is therefore necessary to add together the measuring times of all sensors connected. The sum of these measuring times constitutes the shortest possible query interval. The DuoSens is parametrized by entries within a function (right side of the window). If only entries or changes are made here, the measurement memory will remain intact with each change.
23
Save/load DuoSens configuration The functions Load and Save are provided to archive the DuoSens configuration on a PC. In this way, for example, you can provide multiple DuoSens units with the same configuration. To store a configuration Select the Configurations | Store menu or main window ➝ the operating program saves the configuration under the name and number of the DuoSens. When changes are made to a configuration that has already been stored, confirm in the Warning window, This configuration name already exists! Overwrite? with yes (otherwise, save the configuration under another measurement station number). To load a configuration, proceed as follows Select Configurations | Load menu or window. If a configuration is already open: in the Confirmation, Ignore changes? window, confirm with yes (save configuration first if required). In the Stored DuoSens Configurations window, select the configuration required by double-clicking it ➝ the operating program loads the configuration.
Reading/programming the DuoSens configuration The Read function loads the configuration from the DuoSens to the operating program. The Program function programs the configuration created in the operating program into the DuoSens. To read in a configuration: Select the communication path and transmission rate for reading in in the main window: Data transmission line (see accessories) – RS-232 C/V.24 – IrDA OTT DuoLink optical reading head (see accessories) – IrDA OTT IrDA-Link optical reading head (see accessories) – IrDA Linkit adapter Infrared interface adapter – IrDA built-in integrated optical interface (e.g. notebook; only Windows 95 and Windows NT) – AT modem/adapter serial modem or terminal adapter – ISDN CAPI 2.0 ISDN PC communication card with CAPI interface – COM 1 … 99 "COM" interface of the PC used – auto … 115200 Transmission speed standard: "auto" For communication path RS-232 C/V.24 and IrDA variants: Select "DuoSens | Read" menu or main window ➝ the operating program reads the configuration from the DuoSens. For a configuration that has already been opened, confirm the "Reject Changes?" security query with "yes" (if necessary, store configuration beforehand). For communication path AT modem/adapter and ISDN CAPI 2.0: Select "DuoSens | Read" menu or main window ➝ the operating program opens the DuoSens AT modem/adapter window. For a configuration that has already been opened, confirm the "Reject Changes?" security query with yes (if necessary, store configuration beforehand).

Confirm with "OK" ➝ the operating program establishes a connection and reads the configuration from the DuoSens.
To program a configuration Caution: The measured values stored in the DuoSens are permanently lost when programming a new configuration! If necessary read out measured values before programming! Select the DuoSens| Program menu or main window. In the window Warning, configuration changed! Reset DuoSens and delete data memory? Confirm with yes ➝ the operating program programs the configuration into the DuoSens.
Importing/exporting the DuoSens configuration To transfer a DuoSens configuration, via diskette or E-mail for example, the functions Import/Export are available. Likewise, a configuration can be sent via Export as an XML file to the Hydras 3 application software. In the process, the Hydras 3 application software automatically applies all of the measurement stations/sensor configurations to a Hydras 3 workspace.

Value range 0 … 99 seconds. This enables, for example, the required “checking in” of a GSM modem to the cell phone network before remote data transfer.
If at least one activation time is set with an appropriate duration, the DuoSens is ready for a passive remote data transfer. At the same time, within this time period, remote access with the operating program is possible (maintenance windows). For active remote data transfer, no activation times are necessary. The DuoSens automatically switches the switching output when a transfer is due. The “Activation control via switching output at terminal block” and the required lag time must be set in all cases! Example: With the settings shown in Figure 24, the voltage output (M 3-4) is switched on daily at 10:00 and 18:00 for 60 minutes. The lag time at 10:00/18:00 is 30 seconds in each case.

In an alarm situation, the DuoSens sends an SMS text message to the service center of the cell phone network provider. The cell phone network provider converts this SMS text message into an e-mail (e-mail via SMS). For alarm message: The fax prefix number of the GSM serv-ice center (e.g. in Germany 99 for T-Mobile and Vodafone). In an alarm situation, the DuoSens sends an SMS text message to the service center of the cell phone network provider. The mobile network operator converts this SMS text message into a fax (FAX via SMS). PIN (Personal Identification Number) of the SIM card. Format: 4-position. (The PIN for a SIM card can, for example, be de-activated in a cell phone. This is a security risk. In this case, leave the entry field empty -> the operating program repre-sents a deactivated SIM PIN as “0000” when reading in the configuration again.) Caution: If the PIN is entered incorrectly, after the third attempt to activate the GSM modem the SIM card is automatically locked. In this case, the SIM card must be unlocked with the PUK e.g. in a cell phone.
Setting up passive remote data transfer: Passive remote data transfer requires the following settings: – “ Modem/terminal adapter connected to RS232C” activated – Suitable initialization string set for the modem/terminal adapter – If the modem is not permanently supplied with electricity: “Activation control via switching output at terminal block” set to “M 3-4” and at least one activation time with the necessary duration set. The connection is made by the operator in the central evaluation point. Passive remote data transfer is independent of whether any additional active remote data transfer is set up and avail-able. Avoid overlapping time settings for active and passive remote data transfer!

Data transmission by SMS text message The DuoSens automatically and cyclically sends SMS text messages with measurements via a GSM modem. It is possible for the direct receiver to be a Large Account of a cell phone network operator or a PC with GSM modem and the Hydras 3 Rx software. The transmission of the measurements is carried out in the OTT protocol binary. The SMS text messages transmitted cannot be read as plain text in contrast to conventional text messages (coded).

Note The validity of the SMS text message with measured values is 4 days.
Data transmission by dial-up telephone connection The DuoSens automatically and cyclically establishes a telephone dial-up connection via a modem (grid bound or GSM) or an ISDN terminal adapter. The direct receiver must be a PC with suitable modem and the OTT Communication Manager software. The transmission of the measurements is carried out with the OTT protocol binary or the OTT binary CRC protocol.

Data transfer using the packet oriented mobile radio transmission service GPRS The DuoSens transmits measurements automatically and cyclically using a GPRS compatible GSM modem and packet oriented mobile radio transmission. For this, the TCP/IP protocols (Transmission Control Protocol/Internet Protocol), HTTP (Hypertext Trans-fer Protocol), FTP (File Transfer Protocol) and SMTP (Simple Mail Transfer Protocol) can be selected. The immediate receiver is an appropriate server, depending on the protocol used. In the case of FTP, the receiver can also be an OTT Linux Box. With the HTTP protocol, a PHP script must be installed on the receiving server (PHP = hypertext preprocessor, script language) that receives the data, prepares and distributes them. With the FTP, SMTP and HTTP POST protocols, the DuoSens transmits all measured values that have been recorded since the last successful transmission time; for the HTTP GET protocol, the last saved value. The packet oriented mobile radio transmission GPRS also allows a server based time synchronization of the DuoSens (also with a PHP script). Generally, with remote data transfer by GPRS, it should be noted that the availability of the mobile radio transmission by the network provider is not guaranteed. The availability is dependent on various conditions, for example the concurrent use by multiple users within a network cell. Also, good GSM network coverage (high signal strength display on a cell phone) is no indicator of the availability of the GPRS service.

More information on this can be found in Chapter 10. General tab Fig. 38: Input window "Display/ Observer", "General" tab.
Available settings
Observer Manual input
activates the level monitoring function. In this way, you can enter check values at the DuoSens via the jog shuttle and the LCD display. Calculate manual input value with scaling scales the measured value shown on the LCD display. The scaling is only available for channels for which the "Scaling y = ax + b" or "2-point scaling" function block is present in the configuration (see Chapter 9.11). The scaling also affects future stored values. Suppress display of instantaneous value before input suppresses the instantaneous value on the LCD display until a control value is input (display: ********). Extended observer (store and transmit number)
activates the extended level monitoring function. In this way, you can enter observer notes at the DuoSens via the jog shuttle and the LCD display. Transmit text additionally the DuoSens stores and transmits the actual observer text as well as the up to four-digit text number. Independently from this setting, the DuoSens always transmits freely editable observer texts. Password for display (‘Address No. / PIN’ from COM1)
activates the password protection for the LCD display. The password used can be set in the "General" tab of the "Communication interface COM1" entry window (see Chapter 9.4). Date/time operation – this setting specifies whether the date and time can be set via the jog shuttle and LCD display (see Chapter 10.4). – Date and time: Date and time can be set – Only time: only the time can be set – Disabled: Date and time cannot be set. (Recommendation with a satellite transmitting device attached (OTT HDR) or when using the “Time synchronisation” GPRS function.)

Observer texts tab Fig. 39: Input window "Display/ Observer", "Observer texts" tab.
In this table up to 200 freely chosen observer texts for the extended level monitoring function can be entered. Maximum text length: 60 characters. Each table entry (line) consists of a sequential line number, a text number of up to 4 digits (alpha-numeric characters are also possible) and the actual observer text. The "|" character in the table header identifies the line break on the LCD display after 20 characters. In standard cases, the DuoSens only saves and transmits the text number of the observer text. This assumes that the observer texts that belong to the text numbers are available for the data evaluation. If required, the actual observer text can also be transmitted. This does, however, require more memory and also takes accordingly longer with remote data transfer using a modem. Configuration see above ( Transmit text additionally). Buttons Insert
Delete Load Save
Inserts a new line in the table above the cursor position. (entries can only be made in lines that are provided with a sequential line number.) Deletes the line identified with the cursor from the table. Loads an already existing and saved table (.txt file). Saves the table on the PC with any name in .txt format. (As long as the above-mentioned conventions are adhered to, the table can also be edited with any text editor. The text number must be separated from the observer text with a tab space.)
Note The 4-digit text number does not have to be entered in an increasing sequence. The sequential line numbers of the table entries are decisive for sorting. A table entry with the text number 0000 (without observer text provided) allows the entry of freely editable text at the DuoSens. In addition, the flexible entry of a 4-digit number/ID is possible. With free text entry, an observer ID (code) can be realized, for example.

"y=ax+b scaling" Fig. 56 Setting linear scaling.
Linear measurement scaling according to the formula "y = ax + b" Value range only positive ➝ Value range: 0 … +65500
(standard value range ±32 750) Notes: Only DuoSens standard version (with LCD display): To change an instantaneous
value in the DuoSens display (scale), this function block or the "2-point scaling" is required in the relevant channel. Entering a = 1 and b = 0 has no initial effect, but later enables scaling to be performed in the DuoSens display. Example To refer a water level value to sea level, the measured value must be provided with an offset (measurement constant). If the level reference point is at 178 m above mean sea level, for example, the scaling equation is "y = 1· x + 178". Caution Note maximum value range! The DuoSens/the OTT transfer protocol allows a maximum value range of ±32 750 (alternatively 0 … +65500). If it is necessary to scale above this value range, this must be done in the following evaluation software (for example in the Hydras 3 application software).

Entering X = 0; Y = 0 for point 1 and X = 100; Y = 100 for point 2 has no
initial effect, but later enables scaling to be performed in the DuoSens display. To provide as much processing precision as possible, select the X value for
point 1 and point 2 to be as far away from one another as possible (within the measuring range). Example This function is for converting a level value into a depth value, for example. Example: Point 1: X = 0; Y = 15; Point 2: X = 10; Y = 5 (increasing water level in an observation well ➝ falling measured value and vice versa).
"Linearization table" Fig. 58: Setting linearization table.
The linearization table offers the possibility of calibrating non-linear characteristic curves of a sensor. For this you have 20 data pairs for a determined input value "IN" and the calibrated output value "OUT" of a sensor. Intermediate values are interpolated as linear by the DuoSens. Likewise the values above/below the smallest/largest value pair in the linearizer table; Exception: “ no extrapolation“ is marked. Load
Loads a linearizer table from a “.txt” or “.csv” file, e.g. from the OTT Prodis software. The entries in this file must each be in one row as “input value;output value”.

The sampling interval must be a whole number within the mean interval (e.g. sample interval: 10 minutes; mean interval: 1 hour ➝ the DuoSens stores an arithmetic mean from 6 sample interval values each hour). Minimum number of valid values for mean calculation (valid values = no error messages stored, see Chapter 19). Time delay in hours:minutes:seconds indicating the amount of delay between the mean interval and the time raster (maximum of half the interval width of the mean interval). This enables an optimal display of the curve of the mean values. The stored time of day of the mean is at the center of the mean interval; otherwise it is at the end of the mean interval.

Time shift in hours:minutes:seconds indicating by how much the interval over which the sum is calculated is shifted compared to the time raster (maximum of half the interval width of the interval). This enables an optimized display of the curve of the sum values. The stored time of day of the sum is at the center of the interval over which the sum is calculated; otherwise it is at the end of the interval. The saved date of the sum originates from the end of the interval during which the sum calculation was carried out, otherwise the day with the highest number of values determines the date. Example: Precipitation sum from 07:30 until 07:30 the next day; ➝ date of start day, ➝ date of following day Instead of the sum of the previous intervals, outputs the sum value for the current measurement cycle.

"Storage delta" Fig. 62: Setting storage delta.
Do NOT store zero values Storage delta value
The DuoSens only stores measured values that are not equal to 0. The DuoSens only saves a measured value if this measured value differs from the previously saved measured value by the storage delta value. (storage delta value = 0 ➝ the DuoSens saves all measured values.)
Note The "storage delta" function produces aperiodic time sequences ➝ in the
"Store" function block, select "Always store with time". If the storage delta value is not equal to 0 and if a measured value is ready to
be stored in the DuoSens, the DuoSens also stores the previous measured value afterward (which, however, did not exceed the storage delta value). This process optimizes the display for graphical evaluation of measured values. Example sample interval: mean interval: storage delta value: stored values:
1 hour 1 hour 0.05 m 11:00:00 AM; 1.20 m 07:00:00 PM; 1.21 m 08:00:00 PM; 1.28 m

"Store" Fig. 66: Store.
Function Stores the measured values taken in this channel to a non-volatile memory. This function is absolutely necessary at the end of every channel. For periodic measurements, the DuoSens only stores the actual measured value and not the time. Settings Always store with time also stores periodic measured values with the time and transmits these in the OTT protocol.
"Instantaneous value" Fig. 67: Activating instantaneous value display.
Activates the determination and display of an instantaneous value for this channel on the LCD display (level monitoring function; DuoSens standard version) and in the "instantaneous value" function of the operating program (DuoSens basic version). Settings
Scaling (only for display)
Measurement scaling according to the function "y = ax + b". This function only affects the instantaneous value shown on the LCD display/in the instantaneous values window. Stored values are not affected. Factory settings: □; a = 1; b = 0. Unit dimensional units for the (scaled) instantaneous value shown on the LCD display/ in the instantaneous values window. Example To refer a water level value to sea level, the measured value must be provided with an offset (measurement constant). If the level reference point is at 178 m above mean sea level, for example, the scaling equation is "y = 1· x + 178". Caution Note maximum value range! The DuoSens/the OTT transmission protocol alows a maximum value range of ±32 750 (or 0 … +65500 with a preceding scaling module “Scaling y=ax+b“ or “2-point scaling“). Note If in the configuration of a channel there is an additional "2-point scaling" prior to scaling the instantaneous value, or a "y=ax+b scaling", the effects are additive.

Caution: The function block “Communication interface COM1” also accesses the M 1-2 and M 3-4 terminal blocks.
9.13 Special Function Settings
Fig. 69: Measurement output tab.
The DuoSens allows creation of so-called virtual channels. In these virtual channels, the DuoSens does not process and store any direct input signals, but measured values that are transferred from another channel. For example, measured values are not scaled in an original channel, but in another, virtual channel these measured values are scaled according to y = ax + b or according to a 2-point scale. A virtual terminal must always be defined in the tree diagram prior to the virtual sensor associated with it.

The manual sensor makes it possible to enter so-called "manual values" (for example, by an observer reading the value from a level slat) into the database of the DuoSens (see Chapter 10.5). Exceptionally, this channel only includes the function blocks "Manual Sensor" and "Store" (the function blocks "Meas. cycle" and "Instantaneous value" are not needed.)

Note The "Detect and display instantaneous values" function initiates an instanta-
neous value measurement. Until this measurement is complete, the display refers to the last stored value (or the instantaneous value last displayed, whichever is the most recent). On the display, this is identified with an "s" after the channel number (sensor number). After completing the measurement, the new measured value appears without additional identification. The DuoSens stores each call of the "Detect and display instantaneous values" function (observer) in the info channel with date and time. After "Read In" and "Accept" this information can be displayed in the evaluation window of a sensor in the Hydras 3 application software using the "Info Data | Station | Displays" function (observer entry general). If the "Observer manual input" option in the "Display/observer" function block is activated, the DuoSens also stores the check value entered and the currently measured instantaneous value in addition. These two values can be displayed in the evaluation window of a sensor after being "Read In" and "Accept" to the Hydras 3 application software using the "Info Data | Sensor | Displays" function (observer entry with control value input).

13 Alarm management The DuoSens is in the position to automatically generate an alarm if certain situations (limits) arise. An alarm can trigger three different actions: Transfer of the alarm via modem (analog telephone network/GSM cell phone
network) connected to the DuoSens, a terminal adapter (digital, ISDN telephone network) connected to the DuoSens or via a satellite transmitter. To shorten the time interval in which the DuoSens transmits data independently. For this there are five additional time intervals controlled by limits. Control of external devices via a potential free switching contact (electronic relay) and/or a voltage supply switching contact (switched UBat). In the DuoSens operating program there are three function blocks present for configuring the alarm management: Alarm management function block
this function block can be found in the upper section of the tree view concerning the whole DuoSens. In the entry window of this function block there are general parameters to be entered such as addresses, telephone numbers, communication paths and communication and protocol types. Limit function block
Limits are entered in the entry window of this channel function block that trigger a limit alarm (for all inputs except status input). Status alarm function block
Limits are entered in the entry window of this channel function block that trigger a status alarm (only for status input).
Fig. 116: Tree view of the DuoSens function blocks in the left part of the operating program main window. The three function blocks Alarm Management, Limit and Status Alarm are responsible for alarm management. The information in brackets after limit and status alarm are the addresses/address groups to which the DuoSens sends an alarm. With the Limit function block, the set limit value is entered in addition.
13.1 Input window function block alarm management The DuoSens differentiates between individual addresses and address groups. (an address group consists of at least one address.)

73
– SMS: In the case of an alarm, the DuoSens sends an SMS text message to a mobile telephone, for example. In the address entry field, the telephone number of an SMScapable remote station must be entered. (with various mobile network operators it is possible to also send SMS text messages to conventional fixed line connections – SMS-To-Speech.) – FAX (via SMS): In the case of an alarm, the DuoSens sends an SMS text message to the Service Center of the mobile network operator. The mobile network operator converts this SMS text message into a fax. In the address entry field, the telephone number of a fax connection must be entered. In addition, in the entry view of the "Communication interface COM1", the fax prefix number of the GSM Service Center must be entered in the "Modem/adapter" tab (e. g. in Germany, 99 for T-Mobile and Vodafone) – E-mail (via SMS): In the case of an alarm, the DuoSens sends an SMS text message to the Service Center of the mobile network operator. The mobile network operator converts this SMS text message into an e-mail. In the address entry field, an e-mail address must be entered (+ separator specified by mobile network operator). In addition, in the entry view of the "Communications interface COM1", the e-mail calling number of the GSM Service Center must be entered in the "Modem/adapter" tab (e. g. in Germany, 8000 for T-Mobile and 3400 for Vodafone) Protocol type – Text: Alarm forwarding to a terminal program ➝ communication type: Modem active – OTT protocol standard: Alarm forwarding to Hydras 3 ➝ communication type: Modem passive No. of dialings/ Number of dialing attempts and time between attempts in minutes. Pause [min] If previous With communication type modem active/passive: this always ➝ the DuoSens always sends an alarm message to alarm not this address; only alternatively ➝ the DuoSens only sends successful an alarm message to this address if the alarm message to the previous address was unsuccessful. Cycle Limit In the case of an alarm, the DuoSens alternatively uses – instead of the transmission interval defined under Cycle (transmission Standard – this time interval for data transmission interval) Alarm Transmission interval ➝ changes the transmission interval activates/sends for the alarm message in the case of an alarm Alarm message ➝ transmits an alarm message in the case of an alarm If required, additional addresses can be created by clicking on the New button. Continue with creating address groups (see below). Note Delete address: Select address (blue background) and press PC button Del
(delete). Fax and e-mail transmission via SMS text message must be switched on and set

Set/enter limit definition at which the DuoSens generates an alarm: Mode Standard (not changeable) Value >= (greater than or equal to) or <= (lesser than or equal to) limit; for status alarm: 1 or 0. Example: Alarm generation for a value greater than or equal to 1.60. Hysteresis Value by which the measured value must decrease/increase before the DuoSens generates a new alarm. Example: Renewed alarm generation only when the value has dropped to at least 1.55 and then again increased to 1.60. Tolerance Number of measurement cycles in which the limit has to be period reached before an alarm is generated. Example: The first (meas. cycles) time the value 1.60 occurs, the DuoSens generates an alarm. Alarm if Alarm generation also for error state (measured value). value error Alarm also Alarm generation also with subsequent undershootat limit end ing/exceeding of the limit threshold. Example: If the value sinks again under 1.60, the DuoSens also generates an alarm. Send alarm to Address or address group to which the DuoSens sends the address (group) alarm. (Address/address groups saved in function block Alarm Management.) Text SMS Only for status alarm: content of the SMS sent by the DuoSens in the case of an alarm (max. 160 characters) Gradient limit (additional) Value:
Additional condition independent from the static limit at which the DuoSens also generates an alarm. Increasing: ➚; Decreasing: ➘; Increasing and decreasing: ➚➘. Example: If the value rises by 0.5 between two measurement cycles, the DuoSens generates an alarm.
Dead time

15 Date and Time Settings The internal clock of the DuoSens is a realtime clock with high accuracy. If the supply voltage is interrupted, the installed lithium battery provides the voltage supply for the realtime clock. The date and time are set through the DuoSens operating program. Set the date and time as follows Set up the PC/DuoSens communication link (see Chapter 8). Select menu DuoSens function Date/time ➝ the operating program opens the window DuoSens – Date/time and reads out the date and time of the DuoSens. Press Set time button ➝ the operating program sets the DuoSens date/time according to the PC time /date or the date/time set in the two selection fields. If necessary: Press the Update button➝ the operating program reads out the DuoSens date and time again. Press Exit button. Caution: If the PC is on summer time mode (ID: PC (DST)), the operating program automatically uses the standard time without summer correction (winter time). To maintain continuous time sequences, it makes sense not to use summer time in the DuoSens. (the DuoSens does not have an automatic summer time adjustment)
16 Deleting Data Memory Caution: The stored measured values in the DuoSens are permanently lost when deleting the data memory! Where necessary, read out the measured values before deleting (see Chapter 11). Delete the data memory as follows Set up the PC/DuoSens communication link (see Chapter 8). Select theDuoSens menu function Delete Data Memory. Acknowledge the warning Are you sure you want to delete data memory? with yes ➝ the operating program deletes the complete data memory of the DuoSens (all measurements including the information channel). The deletion of the data memory takes about 30 seconds. Afterwards, the DuoSens determines and stores the measured values of all channels available at the sample interval set in each case.

18 SDI-12 transparent mode For maintenance or calibration work on a sensor with SDI-12 interface, the DuoSens has a so-called "Transparent mode". Using a kind of terminal emulation in the DuoSens/LogoSens operating program, it is possible to directly communicate with the sensor via the DuoSens. For this there are the so-called "extended commands" available in the SDI-12 specification. In this case, the DuoSens transfers the commands to the sensor, activates it, and returns the responses of the sensor to the terminal window. Further information on the "extended commands" of an SDI-12 sensor can be found in the operating instructions of the sensor. Please note: Note case sensitivity. Incorrect entries are acknowledged by the sensor with < Error > . If communication is erroneous, end terminal mode (ESC button), wit 5 seconds, then restart terminal mode. If the DuoSens is in measuring mode (e. g. sample interval of a sensor is active), the reply from the sensor is delayed. Start the SDI-12 transparent mode as follows Connect the RS-232 interface of the DuoSens with a serial interface of a PC (e.g. COM 1) . Start the DuoSens/LogoSens operating program. Set communication parameters in the DuoSens main window: – RS-232 C/V.24 – COM1 – 19200 Start terminal mode: Select DuoSens | Terminal mode menu. Wake DuoSens: A
reply: ?08 Start SDI mode: CL/SDI/TRANSP/A "A" stands for the terminal to which the SDI-12 sensor is attached. Entry prompt for SDI-12 commands appears: SDI-12> Example - Switch off sensors: SDI-12>aX0! Answer: aX0
