Through the installation expect suitable protections to avoid product overheating (eg. a shelter to avoid direct sunlight); similarly for low temperatures. Do not open in case of bad weather conditions (rain, snow, etc). Expect the recurring substitution of the hygroscopic salts. Do not install in small locations and/or without ventilation, with high humidity, in potentially dangerous areas or where is prescribed the use of explosion -proof components. Electrical connections on the product must be executed only from qualified and expert personnel, in compliance with actual rules and regulations. For external network powering, the plug at the end of the cord has ground contact; the grounding of the powering is provided from the plug inserted in the socket. The product powering source must be divided from dangerous voltage parts with double insulation and must guarantee insulation of at least 3000 Vrms. Be sure to have, in the plant, suitable protection from an electric short circuit (for example high sensitivity differential circuit-breaker at the root of the AC/DC power supply unit). Before any maintenance on the product, the powering must be disconnected. Avoid any action that can short-circuit the rechargeable battery poles. To enable the product protections, expect a connection to the ground plant through a proper green-yellow grounding connector; this connector must be connected to the proper ground clamp (or to any bolt if it is a metal cabinet). Verify periodically rechargeable battery voltage; expect a substitution after roughly 5 years and if the voltage measured on the poles is too low (eg. 10.5V for a battery with nominal voltage 12V) and investigate on the causes. Using the product differently from the one expected from the manufacturer can compromise safety conditions. The use of parts other than original spare parts could lead to irregular functioning or even dangerous situations for a person and things. 03 TABLE OF CONTENTS QUICK START 6 WEB INTERFACE 39 Overview 6 WEB PAGES FUNCTIONALITY 39 DEVICE OVERVIEW 6 Web interface Language setup 40 Connections 6 Configuration of local analog channels 40 Front Panel 6 Input Configuration 43 Rear Panel 8 Multiplexer Configuration 47 Cabling 8 MODBUS SENSORS 51 Overview 8 What’s Modbus? 51 Power Supply 8 Digital Sensors Configuration 52 Connecting PSU 9 Output Configuration and Alarms 1&2 54 Analog Channels Connection 9 Virtual Channel Alarm 55 Examples 10 Tips 56 Digital Inputs Connection 18 DATALOGGER CONFIGURATION 58 Example 19 Overview 58 Digital Output Connection 20 Configuration -> Datalogger 58 RS485 SmartModbus Connection 20 ALARMS 61 Multiplexers Connection 21 Overview 61 Configuration 61 SETUP 22 SMS Configuration 62 POWERING THE DATALOGGER 22 Email Configuration 63 Default OM-240 Settings 22 SMTP Configuration 64 Direct connection (LOCAL) to the Datalogger 22 FTP Configuration 64 REMOTE CONNECTION TO THE DATALOGGER 23 Channel Alarm Types 65 IP Computer Settings 23 Low and High Thresholds 65 Overview 23 Derivate 65 Description 23 Examples 65 WEB CONNECTION AND OPENING 25 DIGITAL INPUTS CONFIGURATION 66 Overview 25 Example of Digital Input IN1 Configuration 69 Description 25 Example of Digital Input IN2 Configuration 71 CONNECTION THROUGH DHCP 26 VIRTUAL CHANNELS 73 Overview 26 Overview 73 Description 26 Why are Virtual Channels Implemented? 73 Display and Keyboard Functionality 29 Scripts 74 Keyboard Overview 29 Virtual Channel Configuration 76 Display Overview Firmware and Web Updates – Vibrating Wire Firmware Update Data Download 30 Common Errors and Warnings 77 32 ADVANCED CONFIGURATION 79 Overview 79 Datalogger Stop and Switch Off 35 Connections 79 Display Language Setup 37 Measure log data transfer 81 Account Management 82 04 32 TABLE OF CONTENTS Date and Time 83 TROUBLESHOOTING 103 Energy Management 84 BASIC TROUBLESHOOTING 103 Info 84 LOCAL/REMOTE COMMUNICATION 104 CHARTS 84 EMAIL SENDING 106 Overview 84 FTP SERVER SENDING DATA 108 Activation 85 MEASURE 109 Setup and use 85 APPENDIX 110 MODBUS TCP (SCADA INTEGRATION) 90 APPENDIX A: WIRING SCHEMES 110 Overview 90 2 WIRES SENSORS 110 COMMUNICATION 90 4 WIRES SENSORS 114 Communication Bus 90 6 WIRES SENSORS 119 Measure Register 90 Timestamp details 91 Flag’s Register 91 MAINTENANCE 122 Sensor Acquired 92 SPECIFICATIONS 123 Examples 92 Input X Valid 92 Input X Alarm 92 REGISTER MAP 92 General 92 Analog Sensors Locations 93 Digital Sensors Locations 93 Multiplexers Sensors Locations 94 Digital Inputs Locations 96 Virtual Channels Locations 97 SENSOR BASE ADDRESS 98 Local Sensors (Analog) 98 Digital Sensors (Smart Modbus) 98 Multiplexers sensors 98 Digital Inputs 98 Virtual Channels 98 Event Log Registers 99 STATUS REGISTERS 99 Datalogger Status 100 Next Acquisition 100 Firmware Version 101 Model Info 101 Serial Number 101 Device Name 102 External Digital Input / Output Status 102 05 QUICK START Overview This chapter is about different product’s features, starting from a device overview, and it will show how to connect every available sensor: 1. Front and Rear panel Connection for: 2.Power Supply 3.Analog sensors 4.Digital Inputs 5.RS485 SmartModbus Sensors 6.Multiplexer boards DEVICE OVERVIEW OM-240 is a universal datalogger, capable of reading 0..25mA Current Loop and Transmitter, -10..10V, Vibrating Wire, NTC, PT100, PT200, PT500, PT1000, Ratiometric, Wheatstone Bridge, Thermocouple, Potentiometer and SmartModbus RS485 Digital Sensors. It provides a maximum of 24 channels when using only 2 wires sensors. OM-240 is expandable with SmartMux device. Connections Front Panel Figure 1 06 Front Panel Figure 2 The majority of connections are located In OM-240’s front panel: • RS232: it can be used to connect a 3G Modem to expand connectivity • Ethernet: This port is used to connect the device to an existing LAN. Internal Web Server can be browsed to configure and download acquired data. It can be used for Internet connection (Cloud, FTP and EMAIL connections) • USB Host: it allows the user to download measures, events and alarm logs to a pendrive, or to update the firmware • V OUT: this connector is designed to output the same voltage applied to V IN. It can be turned off automatically when logger is in sleep mode or be kept always on. • RS485#2 – V OUT: This is SmartMux port, which allows the connection of 16 SmartMux in daisy chain and offers power supply. • RS485#1 – V OUT: This is SmartModbus port, which allows digital sensors connections and offers power supply. • V IN: This port is to power the datalogger. It’s designed to work in 10-30V range. • PWR-CONFIG: This port will allow the selection of Power supply. A jumper between two rightmost connections is needed to let the datalogger be powered up. • ANALOG INPUTS: This 8 terminal blocks is used to connect analog sensors. Starting from bottom-left to bottom-right we find channels from 1 to 12, and from top-left to top-right we find channels from 13 to 24.Every 6 connections, there is a Ground connector designed to be the termination of shielded cables. 07 Rear Panel Figure 3 OM-240’s rear panel has 2 Digital Inputs and 1 Digital Output. • Digital Inputs IN1 IN2 can be configured to read rain meters and anemometers, or similar pulse sensors (optoisolated, Min input voltage is 5V and Min current input is 2mA, while Max input voltage is 24V and Max current is 10mA, Max frequency 1KHz, accuracy 0.1Hz). • Digital Output is a relay output (for alarms), volt-free closure (low voltage, 30V 2A). Cabling Overview This chapter will explain every connection to datalogger, how to optimize connections availability and to use proper connectors to avoid unexpected behavior (malfunctions). Power Supply OM-240 can be supplied with 10V to 30V. In order to grant correct functioning of every connected sensor or device, and its internal circuitry, at least 2A PSU is needed. If Analog Sensors, External Modems, RS485 SmartModbus Sensors are powered from OM-240, a more powerful PSU should be used. Warning: ALL V-OUT connections on the front panel - in the upper terminal block expose the same V-IN applied. If you apply 24V to V-IN, 24V will be exposed. Since OM-240 can work in a wide range of voltage, use has to choose the right one to power external devices connected. 08 Connecting PSU The logger should be configured before powering it up. New datalogger are shipped already configured (as it follows) to be powered from external power source. Rightmost pins of PWR CONFIG must be short-circuited to allow the datalogger to use V-IN source. Connect V-IN to the right Power Supply Unit. Picture below shows connections. Analog Channels Connection OM-240 can handle sensors up to a total of wires of 48 Examples: 2 wires sensors: up to 24 channels 4 wires sensors: up to 12 channels 6 wires sensors: up to 8 channels User can also mix sensors type and the datalogger will shift positions with this rule: • 6 Wires sensors first • 4 Wires sensors middle • 2 Wires sensors last With this simple rule, it will maximize connection simplicity Here are few examples: 09 Example 1 (2 wires sensors) User connects 4 sensors, all of them are 2 wires: First of all we configure the datalogger to read this sensors, as shown in Figure 4.

Figure 17 S1 S2 S3 S3S4 S5 Digital Inputs Connection OM-240 has 2 digital inputs (on rear panel) that can be configured, independently, as “Trigger” or “Rainmeter/Anemometer”. If they are configured as Trigger, a pulse on the channel will start an acquisition of all configured channels. If they are configured as Rainmeter/Anemometer, input frequency will be measured and logged in measure log. 018 Readable signal specifications: • Min 5V (2mA max) • Max 24V (10mA max) • Max Frequency 1KHz • Accuracy: 0.1Hz Inputs are optoisolated. Example In order to configure a trigger, connect it to DIGITAL INPUTS IN1 (or IN2, not showed here): TRIGGER Figure 18 Open OM-240’s web server, at “Channels Configuration -> Digital Inputs” page. Select Trigger in the IN1 Input field: Figure 19 Edge parameter (Up and Down) indicates if the trigger will raise voltage between poles or drop it, or if it’s a “rectangular” wave, you can choose to use rising front or falling front. Number of reading indicates how many acquisition cycles will be performed after a trigger event. 019 In order to use Triggers the OM-240 should not go in sleep mode. Check Energy Management section to configure the datalogger to avoid switch off (by selecting Always ON). For more information about how to configure Digital Inputs, refer to Digital Inputs section. Digital Output Connection OM-240 is provided with a Digital Output (NC / NO), which can drive low voltage (max 30V, 2A). It’s a relay, so it is a volt-free switch. In order to handle higher voltages or currents, use internal relay to drive a rugged heavy duty relay. RS485 SmartModbus Connection OM-240 can read digital sensor over the RS485 SmartModbus port. The port used for sensors connection is RS485#1. WARNING: RS485#2 PORT DOES NOT WORK WITH DIGITAL SENSORS AS IT IS DESIGNED TO WORK ONLY WITH MULTIPLEXERS. RS485#1 port presents 5 connections: • Data – : can be named as B or “inverting pin” or TxD-/RxD• Data + : can be named as A or “non inverting pin” or TxD+/RxD+ • GND: it is the reference pin. It is recommended to use GND (SC, C, or reference pin) while connecting RS485 sensors. • +V: OM-240 can power RS485 sensors. It provides the same power source applied to OM-240 VIN. Be careful to choose the right supply to power both datalogger and sensor. • GND: same as +V, is the negative connection of power supply. RS485 allows daisy chain connections. The example below shows an OM-240 datalogger with four temperature and humidity probes connected in daisy chain. Figure 20 020 The minimum distance between two nodes (OM-240 to probe, or probe to probe) is 30 cm. WARNING: BE CAREFUL ON CABLE DIMENSIONS, AS THEY ARE AFFECTED FROM TOTAL LENGTH AND PROBE NUMBERS. BE SURE TO CHOOSE A CABLE OF THE RIGHT SIZE FOR YOUR PROJECT. Example Figure 21 Not all probes have a signal GND (SC) pin, and in the example above, the probe was not connected to signal ground. Multiplexers Connection OM-240 offers Analog Sensors expandability through Multiplexers. Multiplexers are expansion boards that can read up to 24 sensors each, with connections logic similar to OM-240 (explained in Multiplexer Section), which will be connected to chan-nel 22/23/24 of OM-240 More than one Multiplexer can be connected to OM-240, up to 16 Units, daisy chained to RS485#2 and channels 22/23/24. 021 SETUP POWERING THE DATA LOGGER The OM-240 is supplied not powered to avoid that during transport the backup battery will discharge.

For some types of sensors it is possible to choose between different units of measure (ex for vibrating wire: digit, Hz, µs). w a rm -up [se c] Field editable from the user. “Warm-up” time of the sensor. It indicates how long the sensor is powered by the OM-240 before starting the measurement cycle. For some types of measurements, this field could be disabled. conve rsion This field allows to select which conversion to realize between LINEAR and POLYNOMIAL. It is also possible to decide to realize NO conversion (in this case the reading is expressed in electrical unit). This field is necessary to convert the reading of the sensor from electrical unit (mA, mV, digit, etc.) to engineering unit (kPa, mm, mbar, etc.) ze ro re a d ing This field is enabled if the linear conversion has been selected.

Num b e r of Sk ip p e d d e cimals Number of decimals recorded for this channel The Data logger does not read the channel, but CSV file will be populated with “skipped” values. This is to ensure compatibility with software population layer in case of sensor change/removal. Some fields will be grayed out depending on chosen sensor. NOTE: in case of a channel with 2 inputs, the second configuration webpage is completely identical to that described above. Other fields could be “blocked” because they are connected to the configuration executed on input 1. 045 The second table on the page it is necessary to set up the possible alarm thresholds for the selected input. In particular: ala rm ty p e High: the input is in alarm only if the reading exceeds the value indicated in field high thre sh old Low: the input is in alarm only if the reading is lower than the value indicated in field low thre shold Derivate: the input is in alarm only if the read- ing differs from the previous reading of a value greater than or equal to the value indicated in field d e rivate high thre shold thre shold Field editable from the user. It indicates the nu- merical value to assign to the high threshold. The value has to be inserted taking into account the unit of measure of the reading. low thre shold Field editable from the user. It indicates the numerical value to assign to the low threshold. The value has to be inserted taking into account the unit of measure of the reading. d e rivate thre shold Field editable from the user. It indicates the nu- merical value to assign to the derived threshold. The value has to be inserted taking into account the unit of measure of the reading. vc ala rm w ith logical op e rations Enabling this tick, the configured alarm is no lon- ger connected to the single input. The channels that adopt this option will be “linked” to each other by logical operations (AND, OR, NOT and XOR). If this field is enabled, therefore it will be necessary to configure a virtual channel with an opportune logical operation. NOTE: the values inserted in alarm thresholds have to take into account the possible linear or polynomial conversion that has been configured. If the user configured a conversion, the threshold values have to be inserted in engineering unit. If the user didn’t configured any conversion, the thresholds values have to be inserted in electrical unit. 046 • Once the configuration of webpage ended, or of 2 webpages in case of a channel with 2 inputs, push save modifications to confirm the created configuration. • It is possible to visualize the scheme of connection of the just configured channel pushing on wiring scheme in page local channels configuration.

Thanks to the tick enable it is possible, pushing on edit, to configure the channels of the selected multiplexer-. NOTE: it is possible to enable at most 16 multiplexers. We advise to enable only the multiplexers that are used. Figure 35 049 • then, the page multiplexer configuration opens. This page allows the sensors insertion thanks to three buttons: add 6 wires sensor, add 4 wires sensor and add 2 wires sensor. Figure 36 • for example, if you push on button add 4 wires sensor in the underlying table a 4 wires sensors is added and it is possible to configure it. Figure 37 • pushing on edit it is possible to set up all sensor parameters, as you do for a local analog channel. The configuration of an analog channel on multiplexer is not different from that of a local analog channel. NOTE: once the configuration of all channels of multiplexer ended, it is advised to push on LOCK. In this way, the configuration is “blocked” and the removal of one or more sensors doesn’t modify the position of those that are configured yet. ATTENTION: the addition of a new sensor to a multiplexer that has been already configured could cause a change in sensors position on multiplexer channels. In case of sensors that are physically already connected to the multiplexer, it is necessary to check that their positions are the same. If the positions changed, it is necessary to re-wire the sensors to the multiplexer.” 050 MODBUS SENSORS What’s Modbus? Modbus is a serial communication protocol, made by Modicon in 1979 to link their PLC. It has become a de facto standard in communication protocol, and it’s now a commonly available means of connecting industrial electronic devices. Advantages in industrial sectors are: • developed with industrial applications in mind • openly published and royality-free • easy to deploy and mantain • moves raw bits or words without placing many restriction on vendors Modbus enables communication among many devices connected to the same network, for example a system that measures temperature and humidity and communicates the results to a computer. Modbus is often used to connect a supervisory computer with a remote terminal unit (RTU) in supervisory control and data acquisition (SCADA) systems. Many of the data types are named from its use in driving relays: a single-bit physical output is called a coil, a single-bit physical input is called a discrete input or a contact. Object Type Access Size Coil Read-Write 1-bit Discrete Input/Contact Read-Only 1-bit Input Register Read-Only 16-bits Holding Register Read-Write 16-bits 051 Digital Sensors Con iguration For digital sensors, the OM-240 family offers an in-depth configuration. After choosing Baudrate and Maximum RS485 Address (Fig.1), the User can “Save Changes” and start the con-figuration of the sensors. Figure 38 Figure 39 By clicking “Edit” (Fig.2) on the sensor row to configure, the system shows typical sensor (IPI, H-LEVEL, TILTMETER) and a SmartModbus element (Fig.3). SmartModbus is selected if the User has a generic modbus sensor. 052 Figure 40 Click “Next” to proceed the configuration. Fig.4 shows MODBUS parameters. These are usually provided by the sensor’s manufacturer and reported in either the datasheet or instruction manual. Figure 41 Modbus Address is sensor’s modbus address, usually settable from the sensor. Pre Measure Actions: Some sensors require either a command or a condition to be true before actually pushing the data in the right register. Send Command enabled orders the OM-240 to push data (Value field) in a sensor’s register (Reg Address (hex)). You can “Force Multiple Reg” o “Write Coil”. 053 Wait Condition enabled let the OM-240 check if Coil, Input or Holding are less, more, equal or different from a chosen Value. It allows also to wait for a certain time. Endianess allows to select if the sensor use a Little Endian or Big Endian data type. Acquire Measures: This section is the actual data reading from the modbus sensor. On most sensors, this is the only section the User should care of. Measure n enabled allows the OM-240 to read the register (Holding, Input or Coil) at the speci-fied “Reg Address (hex)”. Data Type is Signed or Unsigned Integer, Float and Fixend Point. Register Number&Order let the User choose which register and in which order data is stored in. Usually is reported in sensor’s datasheet or instruction manual. Endianess allows to select if the sensor use a Little Endian or Big Endian data type. Post Measure Actions: As Pre Measure Actions, this is not always required, but some sensors need a register to be written in order to return in standby or reset. Settings are quite similar to Pre Measure Actions’ Send Command, which can be enabled or not, and actions are Force Multiple Reg, Write Coil (Register Address is specified in Reg Address (hex) field) and Wait Time. Endianess allows to select if the sensor use a Little Endian or Big Endian data type. Output configuration and alarms 1 & 2 Figure 42 Figure 43 This are channel related settings. The user can specify channel name, a short description, and data conversion. 054 Conversion: Linear: if sensor output is linear, the systems needs to know Zero Point (Ez) and Sensibility(S) and Number of Decimals (field will be enabled). The output will be equal to Sx - Ez Polynomial: if sensor output is not linear this allows the user to specify sensor output curve, and enable Zero Reading (Ez), Poly.Coeff. A, B, C and D and Number of Decimals. The output will be equal to Ax3 + Bx2 + Cx + D - Ez Engeneering Units: to complete data with the right engeneering unit like bar,°C, °F, %HR and so on. Number of Decimals: after linear or poly conversion, here are the number of decimal digits the system will round the value at. Skipped: the system will ignore this sensor Virtual channel alarm This section enables Logical Operations with Virtual Channels Alarm. Virtual Channels section allows logial operations between alarms, (AND, OR, XOR, NOT). 055 Tips Multiple Sensor in one single Modbus Device Our System allows the user to connect one single Modbus device providing information coming from different sensors. What if a sensor has more than 2 channels? The OM-240 allows to create another sensor with the same Modbus address (Fig.9,10,11), so user can select 4 (or more, creating other sensors) registers to read data from. Pre Measure Actions (if required) will be set only in first sensor (relative to the Modbus slave device) and Post Measure Actions will be set only in last sensor (always relative to the Modbus slave device)” Figure 44 Figure 45 Figure 46 056 Figure 47 Figure 48 057 DATALOGGER CONFIGURATION Overview This chapter will explain following webserver configuration pages: • Change Datalogger’s name • Acquisition speed and precision • IoT Enabling Configuration -> Datalogger Figure 49 This page is dedicated to low levels tweaks to improve stability and correct readings. 058 Serial Number: This is the device serial number. It is composed by 8 decimal digits. Identification: A short string (16 characters maximum) to identify the datalogger. Identification is used for USB data export. Admitted characters are: Letters (a-z, A-Z) Numbers (0-9) Only this special characters: ._()[]-{} Non-admitted characters will be substituted with _ (underscore) character. Measurement Settings (Standard, High Precision, Fast): These are 3 different measure configurations. User can also modify settings, these are recommended settings. Fast Measurement: The datalogger does not execute analog autocalibration. Relay Warmup: Delay time between relay activation and acquisition process ADC Average Number: Number of average computed by Analog to Digital Converter Simultaneous Relay Number: number of simultaneously activated relays Relay time Gain: Relay excitation time (tens of milliseconds) ADC Speed: ADC Sample rate, in SPS (Sample per Seconds) Relay Discharge: before acquisition process, all relays are set to short circuit to discharge capacitors. Relay Reset: Optimization of relays movements Turn Off Analog During Warm-up: during sensor’s warm-up, analog board is temporarily turned off Analog always on: Analog circuits are turned on at first acquisition cycle (in RUN) and then won’t be turned off (except when CONFIG or STOP mode are set). This allows faster acquisition rates. In Test Measure mode, analog board is turned on temporarily then turned off again. If datalogger will go in sleep mode, analog circuit should be re-initialized at next acquisition cycle. Polynomial digit: This field establishes number of decimal digits for channel with Linear or Polynomial conversions. This number is used if the channel is left at “DEFAULT”. A single channel can override this setting in its own setting page. 059 Enable VW Tracking: This option will speed up Vibrating Wire Excitation by lowering the time needed for frequencies scan. VW Noise subtraction: It performs a noise analysis of the channel, to have a better SNR after excitation. VW Excitation: This field enables the excitation of Vibrating Wire. If it’s disabled, no excitation will be applied while reading vibrating wire, thus making the reading impossible. It can be used to test with functions generators. Thermocouple break check: before TC readings, OM-240 inspects TC circuitry to check total resistance. If value is out of thresholds, TC will be flagged as broken, and NAN, +FS or -FS will be recorded. If Thermocouple break check is disabled, this control won’t be executed. It is useful to disable this control when using calibrators or mV sources connected as thermo-couple, since their behavior is not the same as Thermocouple’s wire. FTP file name format: it allows choice between different file name’s formats. Low Battery Alarm Threshold: An alarm will be triggered if V IN voltage drops below this threshold. IOT Configuration IOT Enable: This checkbox, enables the communication with Exosite cloud. Read dedicated chapter for more info. WARNING: BEWARE OF ENABLING THIS FIELD. BEFORE ENABLING THIS FIELD, BE SURE TO DELETE ALL MEASURE LOG PRESENT IN MEMORY. IF MEMORY IS NOT CLEAR, AT THE FIRST ACQUISITION, THE DATALOGGER WILL PROCESS EXISTING DATA AND TRY TO EXPORT TO EXOSITE CLOUD. USUALLY THIS OPERATION REQUIRES FEW HOURS AND THE DATALOGGER WILL BE STRUCK PROCESSING THIS DATA FOR NECESSARY TIME. IOT Cik: This field is dedicated to the CIK field, gathered from Exosite cloud after the creation of a device. Read dedicated chapter for more info. Download/Upload Calibration: it allows logger calibration saving or restoring. Default Settings Recover: It will restore default settings Reboot: it reboots the datalogger 060 ALARMS Overview • OM-240 can handle alarms of both channel (reading out of a determined range) and device (malfunction, wrong configuration etc.) • Alarms can be recorded on Alarm logs and can be sent via SMS, EMAIL, FTP or activate through OM-240’s Digital Output (refer to Chapter1 for more info). • A first configuration must be done in the Alarm Configuration page (on the web server, click on “Configuration” and “Alarms”). The following screen will be prompted. Simple steps to configure alarms: • Select Output • Select “Delay” • Select “End” Configuration Figure 50 In the “SENSOR” section, it is possible to select how OM-240 will handle Sensor’s alarm: Enabling any of this checkbox will modify datalogger’s action: • Send SMS will send an SMS (if RS232 modem is connected) with the Alarm 061 • Send email will send an email (if RS232 modem OR Ethernet connection with internet is connected) with the Alarm, to specified recipient (see next section) • Upload on FTP will upload the Alarm Log’s row (if RS232 modem OR Ethernet connection with internet is connected) with the alarm triggered • Enable Digital Output will trigger the backpanel’s terminal block to control an external Alarm system • Frequency increase will increase acquisition frequency to gather more information about the event that has triggered the alarm. Acquisition Frequency is set at 1 minute when the channel is in ALARM. If the datalogger is configured to read different sensors, and more than one sensor is in alarm, reading frequency will probably be lower. There are pretty much the same options in the “OM-240” Section, except for Frequency increase. Event Nr. Dropdown menu will let you choose the number of events in alarm at which the datalogger triggers the alarm. 1 means at the first occurrence, 2 will skip first value in alarm, and if it still in alarm during next acquisition the alarm will be triggered, otherwise there will be no alarm event. End Dropdown menu will let you choose the number of events after which the datalogger will cease to trigger. NEVER is the option to disable this feature, and let the datalogger trigger EVERY set alarm. After configuration, click Save to proceed. If you selected SMS, email or FTP, the relative configuration option will be activated. SMS Configuration Figure 51 062 This page will let you select SMS recipient for triggered alarms. Number: the recipient(s) of the SMS Sensor Alarm: if you have selected SMS in sensors alarms this will let you use the current recipient for the sensor alarm OM-240 alarm: if you have selected SMS in OM-240 alarm this will let you use the current recipient for the datalogger’s alarm Add Measure in alarm: it will attach measure value to the SMS. Text: it allows a small text writing (up to 30 characters) contained in the SMS Tries: it makes you choose the number of tries if SMS send fail. Click save to proceed. Email Configuration Figure 52 This page will let you select the email recipient for triggered alarms. Address: the email address of the recipient Sensor Alarm: if you have selected email in sensors alarms this will let you use the current recipient for the sensor alarm Datalogger alarm: if you have selected email in datalogger alarm this will let you use the current recipient for the datalogger’s alarm Object: email’s object Text: a small text (30 charaxters) to be sent with email SMTP Configuration: it will open a new page to configure SMTP parameters Save Changes to proceed 063 SMTP Configuration Figure 53 This page allows the setup of SMTP parameter .

The directory MUST exist Username and Password: credentials used to connect to the server Port: port used to connect to the server Tries: number of attempts in case of failure. Save changes to continue WARNING: Only standard FTP (not encrypted) is supported. Channel Alarm Types Thresholds in OM-240 alarm settings are here described. WARNING: all alarms evaluations are computed AFTER linear or polynomial conversion, if any. Low and High Thresholds Thresholds are basically limits to sensor’s ranges. If a threshold is overcome (lower value so low threshold, or higher value so high threshold), the alarm is triggered. Derivate Derivate alarm will analyze, at n sample, value of n-1 sample and compare to n sample. If value(n)-value(n-1)>threshold, an alarm is triggered. Examples Derivate alarm, linear conversion (Ln*S+Lz)-(Ln-1*S+Lz) > threshold Ln is last sample, while Ln-1 is second-last sample. S is sensibility parameter and Lz is offset (Zero reading) in linear conversion’s channel settings. 065 DIGITAL INPUTS CONFIGURATION The OM-240 has two digital inputs (IN1 & IN1) on its back side. Figure 55 The digital inputs could be configured to acquire a trigger or an rain gauge or an anemometer. The trigger could be used with a seismic station and it is used to start one or more acquisitions extemporaneous. NOTE: in case of a rain gauge or anemometer, no elaboration of reading is considered (ex: average speed, maximum, instantaneous, daily storage, etc.) 066 To set up a digital input it is necessary: • to select the entry channel configuration, then digital inputs; • the page digital inputs configuration opens. In this page it is possible to set up 1 or both digital inputs independently; Figure 56 067 • in this page you could find the following fields: inx inp ut (X is 1 or 2) Using the drop-down menu, it is possible to select the type of digital input between 4 possibilities: - d isa b le d - trigge r - rain gauge - w ind gauge The input has to be configured according to the sensor that is connected. acquisition fre que ncy Sampling rate of selected channel (wind gauge, rain gauge) se nsib ility This field enables only for RAIN GAUGE and ANEMOMETER. If it is well configured, it allows to transform the counts in engineering units (ex: from “counts” to “mm”) e d ge This field enables only for TRIGGER. It is possible to select between two entries: Up or d Ow N. The state change could be high-low (DOWN) or low-high (UP). Therefore, if on the input generally there is no voltage and you want to do an acquisition with the OM-240, in case a voltage arrives on the input (ex: 5Vdc) it is necessary to select Up. This because you pass from a low (0Vdc) to a high (5Vdc) state. unit m e asure This field enables only for RAIN GAUGE and WIND GAUGE. It indicates the unit of measure of the read value. num b e r of re a d ings (trigge r) Editable field. Numerical value. This field enables only for TRIGGER. It indicates how many extempora-neous and consecutive acquisitions the OM-240 has to do with a trigger. Acquisitions are done independent-ly from the configured acquisition interval. These data are stored and so they could be exported in CSV file. NOTE: If you enable the digital inputs, the OM-240 is in permanent acquisition. This means that, even if the OM-240 is in Timed, he will never go in “low consumption” mode. This situation has to be taken into account in case it is necessary to optimize the consump-tions (for example with batteries or solar panel) 068 Example of digital input in1 configuration Here is shown the standard configuration of a digital input configured as trigger. • open page digital input configuration and select the entry channels configuration / digital inputs from left menu; Figure 57 • in field input in1 select trigger; • in field edge select up; Figure 58 NOTE: in this example it has been selected UP because we supposed there is any voltage on digital input IN1 and that in case of a trigger, a voltage of 5Vdc is applied. 069 •In field numbEr of rEAdingS (TriggEr) insert the number of acquisitions you want that the OM-240 does after a trigger signal (ex.5) Figure 59 • Push save changes to confirm the configuration. The OM-240, with this configuration, in case it receives a positive voltage on digiTAl inpuT in1, does 5 consecutive acquisitions of all configured channels. A practical example of the use of trigger function is that of associate OM-240 to a Seismic Station. The majority of Seismic Stations has the possibility, in case of a seismic event, to ac-tivated a digital output (an output voltage). If this signal is connected directly to the digital input IN1 of the OM-240, when a seismic event happens the Seismic Station furnishes a digital output on the digital input of the OM-240. The OM-240 starts to acquire all connected sensors to verify the monitoring area after the event. 070 Example of digital input in2 configuration Here is shown the standard configuration of a digital input configured as rain gauge. • open page digital input configuration and select the entry channels configuration / digital inputs from left menu; Figure 60 • in field input in2 select rain gauge; Figure 61 071 • in field sensibility insert the sensibility of sensor (for example 0.2 mm/count); • in field unit of measure insert the unit of measure of the done conversion (example “mm”) Figure 62 With this configuration, the OM-240 acquires the number of impulses for a period of a hour. Once this interval ends, the OM-240 memorizes the number of counts done during this period of time. If for example in one hour 5 counts are detached, the OM-240 applies the following conversion: 5 COUNT * 0.2 MM/COUNT = 1 MM Once tche value is memorized, the counter sets to zero. Alarm configuration is the same as all other channel types, with High, Low and Derivative Thresholds. VC alarm with Logical Operations is present, as a Virtual Channel alarm can be used in Virtual Channels Logical Alarms. 072 VIRTUAL CHANNELS Overview This chapter is focused on Virtual Channels (VC from now on), to understand why VC are implemented on OM datalogger and how to configure them. 1. Why are Virtual Channels implemented in OM Family? – This paragraph shows benefits of Virtual Channels 2. Scripts – Scripts are a fundamental section of Virtual Channels’ architecture. 3. Virtual Channels configuration – “HOW TO” use and configure Virtual Channels’ with analog and digital sensors, digital input and multiplexers. 4. Common Errors – Here are shown common errors made during virtual channels creation, and how to avoid them. Why are Virtual Channels Implemented? We usually use sensors to get a measure. Anyway, we could need a way to modify that number because we need either a derived measure (airflow/airspeed) or an expression calculated on more than 1 sensor (dewpoint or Δt between two zones for instance). We can calculate this with spreadsheet or just let our datalogger do the work. OM Family has this feature with Virtual Channels. Virtual Cannels allows operations to be made on a single channel or between channels. OM group them into Scripts, with a maximum of 5 scripts containing 16 virtual channels each. Each Virtual Channel can handle up to 9 elements (including Virtual Channel beloning to the same script). Figure 63 073 Scripts OM-240 automatically provides the script name during its creation. Acquisition timing can be chosen between 1 second and 7 days, with “DEFAULT” option not overriding OM-240 global acquisition timing. After selecting “Create” button the new script will be listed below: Figure 64 Edit button allows the configuration of Virtual Channels contained by the selected Script. As we see in following Figure, OM-240 provides a large toolbox to program Virtual Channels. Figure 65 074 Figure 66 an: selects an analog channel (prompts a dialog box to input channel number) dig: selects a digital channel (prompts a dialog box to input channel number) mux: selects multiplexer position (prompts two dialog boxes, the 1st for channel number, the 2nd for mux address) cv: selects a virtual channel (only those included in the same script, prompts a dialog box for CV number) Apart from this we have mathematics operations, like +, -, *, /, sin, cos, tan, pi-value. Logical operations allow operations between alarms states. Every channel (analog, digital, virtual and mux) provides a checkbox in alarm configuration, VC Alarm with Logical Operations. This enables alarms to be handled by virtual channels. Figure 67 The following Virtual Channel will trigger an alarm only if one of the two channels is in alarm.

Figure 69 076 Alarm configuration is the same for all channel types, with High, Low and Derivative Thresholds. VC alarm with Logical Operation is present, as a Virtual Channel alarm can be used in Virtual Channels Logical Alarms. Common Errors and Warnings In order to write Virtual Channel’s formula correctly, you should avoid typing the whole formula in the dialog box prompted by the system. G N O R W Figure 70 Figure 71 077 As you can see this causes an error. Formula has to be written using keys printed on the screen. The prompt should be used ONLY to write channel number. The same procedure applies for dig, mux and cv buttons. Figure 72 Figure 73 WARNING: Channel B (1.B, 2.B, and so on) can’t be used on Virtual Channels. If you need to use the channel B of a multiaxis sensor, like Voltage 2CH, Vibrating Wire + Thermistor, and all others, you should use 2 separate channels during configuration. 078 ADVANCED CONFIGURATION Overview Advanced parameters are explained in this section. •Connection configuration, for Ethernet and 3G modem parameters •Measure log transfer, for FTP server configuration •Account management, to change account passwords •Date and Time, to change timezone or set daytime saving •Energy management, to improve power consumption especially if battery powered •Information about firmware versions, mac address, bootloader This section will show how to configure Advanced parameters in the OM-240’s web server.

OM-240 can work in 2 modes: Always On: the datalogger does not turn off itself to save energy, Ethernet connection is available. Timed: The datalogger turns off itself, waking up few minutes before acquisition starting. VOUT port can be kept always on, or timed. Info This page contains information about firmware, web, bootloader and model. Note this parameters in case of assistance enquiry. CHARTS Overview OM240 is provided with a simple tool to generate Charts. It’s available on request and need to be activated with a Purchased Key. Contact your dealer for more information. It’s possible to export data and save charts as pdf, png or vector files. 084 Activation In order to activate charts, you have to buy a key from dealer. Load Data Monitor -> Charts page and insert the key in the right field and click Submit button. Figure 80 Setup and Use From the Web Server pages go in “Data Monitor” and then click “Charts”. This screen will be loaded. Figure 28 Figure 81 No chart is available at this time, and we need to create one. Click on “Configure chart” to proceed. The next screen will ask for Start and Stop date, and you will need a Logarithmic scale (Log scale check) to allow different unit channels to fit the same chart and be readable. 085 Figure 82 Click Next to proceed. Sensor select screen allows channels selection, so you choose which channel(s) you want to include in the chart. One or more sensors should be selected to go further on. Axis selection create up to 3 vertical axis related to that channel. If different scales are presents, this solves readability troubles. Figure 83 086 Color window let the user select the color of that channels. A full palette is available. Figure 84 Marker checkbox, will put markes points on the charts as shown here (AN_0001 has Marker checked, other channels instead do not). Figure 85 Click Next to go on last configuration screen. Here it is possible to choose Chart’s Title, Subtitle, Description and Name. 087 Figure 86 Click “Plot data” to load the chart. Figure 87 From this screen it’s possible to print or download the chart: 088 Figure 88 You can now select the new chart from “Saved charts selection” and Plot every time you need. It can be autoupdated after every new acquisition event by checking autoupdate flag, or manually updated with “update” button, in bottom left area of the window. Figure 89 089 MODBUS TCP (SCADA INTEGRATION) Overview Modbus ADU (application data unit) is sent in form of TCP packets. All Modbus TCP ADU are sent via TCP to registered port 502. Modbus over TCP allows OM-240 integration in LabVIEW and SCADA systems. By reading holding registers, it’s possible to gather all sensors data (analog, smartmodbus, multiplexers, digital inputs), events and alarm, datalogger status and information. • It’s possible to read sensor’s alarm status. • By integrating OM-240 in a SCADA, industrial plant remote monitoring and logging are possible without the need on-site visits. • Maintenance costs are reduced through centralized control and monitoring to minimize downtime. • Centralized alarms to improve operational effectiveness. • Data could be available in mobility (depending on used SCADA). COMMUNICATION Communication Bus Communication bus for this module is Ethernet interface. Port used for TCP communication is 502 (Modbus TCP Standard Port) Modbus function to use for registry reading is ReadHoldingRegister. Measure Register For each sensor (analogs, digitals, multiplexers and virtual channels), 16 registers will be exported. Input A’s last acquired measure (Offset 0-1), input b (Offset 2-3), sensor’s temperature (Offset 4-5), Acquisition’s timestamp (Offset 6-7-8-9-10-11-12-13-14) and different flags to show acquisition status and alarm status (Offset 15). Measures will be communicated in float IEEE754 standard. Endialess can be user configured by writing 0-1-2-3 values into configuration register at 0x5000 address. Following table will represent 4 endianless configurations: IEEE754 = AA:BB:CC:DD AA = MSB DD = LSB Configuration=0 (default) 090 AA BB CC DD AA DD CC DD BB AA CC AA BB MSB Modbus address LSB Modbus address 0 0 MSB Modbus address LSB Modbus address 1 1 Configuration=1 BB MSB Modbus address LSB Modbus address 0 0 MSB Modbus address LSB Modbus address 1 1 Configuration=2 CC MSB Modbus address LSB Modbus address 0 0 MSB Modbus address LSB Modbus address 1 1 Configuration=3 DD MSB Modbus address 0 LSB Modbus address 0 MSB Modbus address 1 LSB Modbus address 1 Timestamp details Timestamp is composed by 9 registers, with offset 6 (MSB) to 15 (LSB). Timestamp is an ASCII string 18 bytes long, in the following format: “dd/mm/yy hh:mm:ss” Flag’s Register Flag’s register is mapped as it follows: BIT Content 1 A valid Input 0 2 3 4 5 6 Sensor acquired B valid Input Valid Temp input A alarm Input B alarm Input Temp alarm Input 091 Sensor Acquired This register is set to 1 when sensor is acquired and a new data is available. SCADA (or Modbus Master) reads the updated register and reset it to 0 by using Coils Functions. In this way the system is ready to note the presence of a new acquisition. This BIT is also accessible through read/write coils functions. Coils are mapped on flag “Sensor Acquired” having referral to base address of each sensor. To obtain Coil address of a sensor, Use the following formula: Coil Address = Base Address/10 Base Address computation will be shown in next pages. Example 1 Channel: CH4 Base Address: 30 Coil Address: 3 Example 2 Channel: DIG2 Base Address: 90 Coil Address: 9 By using Coil functions, Modbus Master will be able to read the entire Coil Vector (858 sensors) in a single Modbus transaction, to understand acquired sensors and to read only updated measures, without the need to read the 10 registers block every time. Input X Valid It indicates if matching Inputs are valid or not. If sensor is configured as Volt 1CH, registers status will be: • Input A Valid: 1 • Input B Valid: 0 • Input temp Valid: 0 For a digital single channel sensor, registers status will be: • Input A Valid: 1 • Input temp Valid: 1 • Input B Valid: 0 Input X Alarm It indicates if matching inputs are in alarm. 092 REGISTER MAP General All this registers are read-only. Only “Sensor Acquired” BIT is read-write, using Write single/multiple coils.

BASIC TROUBLESHOOTING This paragraph provides basic OM-240 troubleshooting tips. ARE YOU UP-TO-DATE? 1. Verify that you installed the last version of firmware 2. Verify that you have an adequate power supply (from photovoltaic module or external power supply) on the V IN clamp of the OM-240; check if the voltage is within the range accepted by the OM-240 and stable. IF THE OM-240 DOESN’T TURN ON. Follow this step, testing after each: 1. remove power supply on V IN clamp for 10 seconds and try to reconnect. 2. verify the presence of jumper cables on the “PWR CONFIG” clamp 3. control that the power supply system works, is correctly sized and respects the character-istic declared on datasheet 4. make sure you hadn’t set the OM-240 in Timed mode using the webpage “Energy management” NOTE: if on the display appears TELNET MODE, contact directly OMEGA Assistancetechnical support for assistance. IF THE OM-240 DISPLAY STOPS RESPONDING Follow this step, testing after each: 1. remove power supply on V IN clamp for 10 seconds and try to reconnect. IT IS IMPOSSIBLE TO UPLOAD THE CONFIGURATION Follow this step, testing after each: 1. on webpage STATUS verify that the OM-240 is in “Config” 2. make sure that the configuration you are trying to upload has been created with the same major release of the firmware on the OM-240. 0103 NOTE: if what is written above is correct, the configuration file could be damaged. In this case, the OM-240 warns with an error message and the file is no more usable. We suggest to repeat the configuration. IF THE OM-240 STOPS DURING AN ACQUISITION Follow this step, testing after each: 1. verify the events log and refer to manual “Codes Alarms-Events” to understand the eventual logs 2. verify that the OM-240 is correctly supplied. If the power supply is below the minimum threshold or over the maximum threshold of power supply, the OM-240 blocks every activity in progress; 3. verify the alarm log to identify the problem and refer to manual “Codes Alarms-Events” to understand the eventual logs 4. Verify if in alarm logs there is an “overcurrent” error. In case of overcurrent, the OM-240 stops the acquisition. 5. verify the available memory. In case of full memory, the OM-240 stops the acquisition. IT IS IMPOSSIBLE TO HAVE ACCESS TO SYS MENU Follow this step, testing after each:: 1. verify that the OM-240 is not acquiring. In this case, wait until the end of the acquisition or go in “DL” menu and select “Stop DL” IT IS NOT POSSIBLE TO DOWNLOAD DATA ON USB FLASH-DRIVE Follow this step, testing after each: 1. verify that the USB flash-drive is formatted in FAT32; 2. verify with the PC that the USB flash-drive is read without any errors. 3. try with a different USB flash-drive LOCAL/REMOTE COMMUNICATION This paragraph provides OM-240 local communication (from PC through a LAN cable) and remote communication (from PC through internet) troubleshooting tips. ARE YOU UP TO DATE? 1. Verify that you installed the last version of firmware 2. Verify that you have the correct power supply (from photovoltaic module or external pow-er supply) on the V IN clamp of the OM-240 0104 IF YOU ARE NOT ABLE TO ESTABLISH THE CONNECTION WITH THE OM-240 . Follow this step, testing after each: 1. remove the power supply on V IN clamp for 10 seconds and try to reconnect. 2. reboot the PC and try to connect 3. make sure you configured appropriately the network card of the PC, that is it is part of the same subnet mask of the OM-240. 4. make sure you are using the correct LAN cable according to the type of network you chose. 5. make sure the OM-240 is not configured in “Timed”. In this case the network card remains switched off. It is necessary to turn it on manually from SYS menu. 6. make sure the OM-240 is not used by another user. The OM-240 accepts only one connec-tion at a time. 7. make sure that the last user that logged on the OM-240 had logged out. Otherwise, it is necessary to wait until the automatic log out. This happens after the time configured in page “Energy management” has passed. You could also reboot the OM-240, in order to not wait for the log out. 8. in case of use of remote communication devices (ex: HSPA router connected to the OM-240), remove them and do a test of direct connection between PC and the OM-240. This is neces-sary in order to exclude problems with communication interfaces. IF USER CANNOT HAVE ACCESS TO THE OM-240 WITH AN USER Follow this step, testing after each: 1. make sure that the access credentials are correct 2. if you logged out with a n user and you are trying to enter again with a different user, delete the browser cache, close and re-open the browser (some browsers are configured in order to memorize passwords) 3. make sure that the last user that logged on the OM-240 had logged out. Otherwise, it is necessary to wait until the automatic log out. This happens after the time configured in page “Energy management” has passed. You could also reboot the OM-240, in order to not wait for the log out. 4. in case of use of remote communication devices (ex: HSPA router connected to OM-240), remove them and do a test of direct connection between PC and OM-240. This is necessary in order to exclude problems with communication interfaces. THE CONNECTION TROUGH THE OM-240 AND COMPUTER GOES DOWN. Follow this step, testing after each: 1. be sure that your PC is not set on Energy Saving mode 2. Try to change the LAN cable 3. Try using another LAN port of your PC or using another PC 4. verify that the OM-240 is not in Timed mode. In this case, once ended the timeout time configured in webpage “Energy management”, the network card turns off if there isn’t any data exchange. 0105 E-MAIL SENDING ARE YOU UP TO DATE? 1. Verify that you installed the last version of firmware 2. Verify that you have the correct power supply (from photovoltaic module or external pow-er supply) on the V IN clamp of the OM-240 This paragraph provides OM-240 e-mail sending troubleshooting tips. THE E-MAIL TRANSMISSION INVOLVES DIFFERENT DEVICES. IN THIS DOCUMENT, WE TRY TO DETERMINE WHICH DEVICE COULD CAUSE THE PROBLEM AND THEN WE TRY TO SOLVE IT. The “system” is composed as follows: 1. OM-240 2. Internet Service Provider (ISP): allows the communication between OM-240 and the e-mail server 3. E-mail Server (ESP): allows to send and to receive e-mails NOTE: it may be that the ISP (Telecom, Vodafone, AT&T, Verizon, etc.) doesn’t coincide with the ESP (Gmail, AOL, etc.) Resolution FIRST OF ALL, INSURE WITH YOUR IPSP THAT: 1. The SIM card or your network is enabled to the internet 2. The e-mail transmission is allowed on the used APN or on the used network SECONDLY, INSURE WITH YOUR ESP THAT: 1. there are no momentary breakdowns on ESP server 2. the username and password of your e-mail account are valid and accepted 3. that the e-mail account you want to use is active THESE POINTS DO NOT DEPEND ON OMEGA ENGINEERING AND NEED TO BE RESOLVED THROUGH YOUR ISP OR ESP. If you don’t have any problem with the ISP and the ESP, you could proceed looking for causes on the OM-240. 0106 IF THE OM-240 DOESN’T SEND ANY E-MAIL ALTHOUGH IT IS CONFIGURED. Follow this step, testing after each: 1. verify the events log and refer to manual “Codes Alarms-Events” to understand eventual logs 2. verify that the SIM is properly inserted in its slot into the communication device (HSPA router or 2G modem) or that your network devices are properly configured to permit the e-mail sending (firewall, port, etc) 3. verify that you inserted your SMTP server account correctly (“SMTP Server Configuration” page) 4. verify that the SMTP account is a simple authentication. The OM-240 doesn’t support SSL. 5. If you use a communication device base on mobile network, verify that there is a mobile coverage (according to the adopted technology e.g: 2G, 3G or 4G) on the site where the OM-240 is installed. 6. If you use a 2G (GSM/GPRS) modem, verify that there is a good 2G signal where the OM-240 is installed. In some place there is only a 3G or 4G coverage. 2G modem is not compatible with 3G, 4G and CDMA networks. 0107 FTP SERVER SENDING DATA ARE YOU UP-TO-DATE? 1.

It can be used in a wide range of applications including HVAC, oil and gas, water quality, energy and building monitoring. With the OM-240 no other configuration/analysis software package is needed as it is provided with a Web server on board; just use a standard Web browser and it is ready to use. Logged data is ready to be shown in graphic “real time” mode (License required) or exported in a CSV file. 0123 SPECIFICATION CPU AND MEMORY • Processor: ARM Cortex-M3 MCU with 1 MB Flash, 120 MHz CPU, ART Accelerator, Ethernet • RAM Memory: 1 Mbyte RAM • Mass Storage: 2 GB SD card for data (about 5 Mega data points) and Web pages • Clock accuracy: High precision RTC (real time clock with battery back-up) temperature compensated • On-Board Sensors: Temperature (accuracy ±1%), measured inside the datalogger ANALOG INPUTS Number of Inputs: 24 differential analog inputs, individually configured. Channel expansion provided by multiplexers. There are 8 terminal blocks (each terminal block can handle up to 3 sensors). The OM-240 is designed to work with 2 to 6-wire sensors. You can connect 2-wire sensors on each channel and read 24 sensors, or 4-wire sensor and read 12 channels. The system will order sensors depending on how many wires they use, placing 6 wires sensors first, 4 wires in the middle, and 2 wires last. Once software configuration is done, clicking on “Wiring scheme” button on the web interface near the sensors will show how to physically connect the chosen sensor to the block. It shows “relative” position, so if you start connecting sensors from the first you will not have to leave “unused” positions (except for the ground connection of every block, if not used). Multiplexers are needed if the total “wires” from sensors exceeds the 48 provided by the OM-240. 0124 SPECIFICATION ANALOG MEASUREMENTS Measurement Rate Analog Initialization (±10V range) Instrument Warm-Up Measurement (±10V range) Maximum Speed Standard Speed 1.70 sec 7.10 sec Depends on sensor configuration 80 ms 1.57 sec Times indicated are not valid for vibrating wire measures Init analog phase is made only once before measurement cycle ADC: 24-bit (22 true bit) differential analog-to-digital converters, 5SPS to 1000SPS, 0-24 average function, auto-calibration and auto-range ANALOG INPUT TYPES Current Loop (2 Wires): 0 to 25 mA range; power supply: 24/10 Vdc, external Transmitter (3-4 Wires): 0 to 25 mA range; power supply: 24/10 Vdc, external Voltage (4 Wires): ±10 mV, ±100 mV, ±1V, ±10V ranges; power supply: 24/20/10/5Vdc, external Servo Inclinometer: ±5V range; power supply: ± 12 Vdc (dual), external Wheatstone Bridge (6 Wires, With Sensing): ±10mV/V range; power supply: 10/5 Vdc, external (max 10 Vdc) Minimum bridge resistance: 200 Ω; power supply: 10/5 Vdc, external (max 10 Vdc) Potentiometer: ±2.5V range; power supply: 10/5 Vdc 0125 SPECIFICATION Thermocouple Input Types and Ranges THERMOCOUPLE (LOGGER @ 25°C AMBIENT TEMPERATURE) TC TYPE RANGE ERROR TC-K From -200 °C to 1370°C ±1,24 °C TC-B From 600 °C to 1820 °C ±1,22 °C TC-J From -200 °C to 1200 °C ±1,04 °C TC-T From -200 °C to 400 °C ±1,99 °C TC-E From -200 °C to 1000 °C ±0,93 °C TC-R From -20 °C to 1760 °C ±1,64 °C TC-N From -260°C to 1300°C ±1,24 °C TC-S From -20 °C to 1760 °C ±1,64 °C RTD Input: 100Ω Platinum (Pt100/200/500/1000) RTD: range -195 to 847°C (-319 to 1556°F); Power supply: 1.2 mA Thermistor (3000 Ω@25°C NTC): Range: -50 to 0°C (-58 to 32°F) maximum error ± 2°C (± 3,6°F) Range: 0°C to 150°C (32 to 302°F) maximum error ± 1°C (± 1,8°F) Power supply: 0.05 mA /0.1 mA/1.2 mA Reading Resolution: 1 µA at FS for 20 mA range; 1 µV at FS for ±10 mV range; 10 µV at FS for ±100 mV range; 100 µV at FS for ±1 V range; 1 mV at FS for ±10 V range; 0.1 °C for Pt100 RTD; 0.1 °C for NTC thermistor; 0.1 Hz for 6000 Hz range; 0.001 mV/V at FS for ±10 mV/V (Wheatstone bridge) 0126 Measurement Accuracy: 0.01% mV/mA FS (0.17% FS for Pt100/Pt200/Pt500/Pt1000) - with Standard Measurement Temperature Drift: < 10 ppm/°C, range -30 to 70°C Input Noise Voltage: 5.42 µV pp Input Limits : ±12V DC Common Mode Rejection: >105 dB Normal Mode Rejection: >90 dB Input Impedance: 20 MΩ typical Switched Output Power Supply: The voltage ‘V OUT’ is switched on and off under program control.
