5. INTRODUCTION

The V7 measured data acquisition module ALMEMO ® 809 is a brand new member in our family of unique measuring instruments - all equipped with Ahlborn's patented ALMEMO ® plug system. The ALMEMO ® plug offers - and has offered for the last 20 years - decisive advantages when connecting sensors and peripherals because all parameters are stored in an EEPROM located on the connector itself; repeated programming is thus no longer necessary. Any

measuring instrusensor or output module can be connected to any ALMEMO ® ment - all in the same way.

However, the new generation of intelligent digital ALMEMO ® D7 sensors, operating in conjunction with our V7 measuring instruments, overcomes all limitations to which the system was previously subject. Each such sensor, irrespective of the device's measuring quantities and ranges, can operate as an autonomous measuring system with up to 10 channels and provide completely new measurable variables with all necessary control functions, calculating functions, or compensation values, with a range of values up to 8 digits and at speeds up to 1 kHz. What is so special about this new generation is that, thanks to the individual sampling rates used, high-resolution variables, both quick and slow, can now very easily be measured and recorded together. Individual functions can be parametrized via a menu stored in the plug itself. To facilitate identification the quantity abbreviations and units have been extended to 6 digits and the measuring point comments to 20 characters. All sensors belonging to the preceding V6 generations can be used on V7 devices but the new D7 sensors are not backwardly compatible with V6 devices. However, they can be operated directly on the PC via the serial interface and an adapter

8 ALMEMO ® 809

Introduction cable. What is completely new with the V7 generation is the channel numbering system. Sensors and sockets are counted from 0 to 9; this is followed by the channels counted as decimals also from 0 to 9; i.e. the first sensor has channels 0.0 to 0.9, the second has 1.0 to 1.9, etc.

Programming and functioning are virtually identical for all units.

The following points apply to all devices in the ALMEMO ® very with each device.

5.1 Functions of the ALMEMO 809

Measured data acquisition module ALMEMO ® 809 is housed in a compact 8-

DU case; it has 9 electrically isolated measuring inputs suitable for all ALME-

MO ® sensors. Given the large portfolio of V6 sensors and now the new, innovative D7 sensors measuring possibilities are nowadays virtually limitless.

Thanks to the external memory connector with a micro SD card and the realtime clock, all incorporated as standard on the ALMEMO ® 809, the amount of data you can record is virtually endless. The ALMEMO ® 809 also incorporates a high-speed 8-MB flash memory sufficient for up to 1.5 million measured values . There are two output sockets which can be used to connect any of the AL-

MEMO ® output modules, e.g. analog output, digital interface, memory connector, trigger input, or alarm contacts. Multiple V7 devices can be networked together by simply connecting them via network cable.

5.1.1 Sensor programming

The measuring channels are programmed, completely and automatically, via the ALMEMO ® plugs. However, the user can easily supplement or modify this programming via the interface.

ALMEMO ® 809 9

5. Introduction

Measuring quantities and ranges

Appropriate measuring quantities and ranges are available for all V6 sensors with a non-linear characteristic, e.g. 10 thermocouple types, NTC and Pt100 probes, and flow transducers (rotating vanes, hot-wire thermoanemometers, Pitot tubes). For humidity sensors there are additional function channels available for calculating humidity variables such as dewpoint, mixture ratio, absolute humidity, vapor pressure, and enthalpy - now on the basis of the latest formulae as per Dr.

Sonntag. Even complex chemical sensors are supported. Measured values from other sensors can also be acquired using the voltage, current, and resistance quantities with individual scaling in the plug itself. Existing sensors can still be used - so long as the appropriate ALMEMO ® plug is connected via its screw terminals. For digital input signals, frequencies, and pulses there are adapter plugs available with an integrated microcontroller. The new autonomous D7 sensors already provide this wide range of features but also in the future they herald as yet unimagined possibilities in data acquisition from both digital and analog sensors and in all manner of data formats. It will even be possible to control the measuring system itself. It is for example possible to connect an increasing range of sensors to the ALMEMO ® V7 measuring instrument and to change sensors without needing to reset.

Function channels

Maximum, minimum, average, and differential values of certain measuring points can be programmed as function channels and can be processed and printed out like normal measuring points. There are also function channels available for special measuring tasks, e.g. to determine thermal coefficient Q/

ΔT and the wet-bulb globe temperature.

Units

The units display (V6 two characters, D7 up to six characters) can be adapted for each measuring channel in such a way that both the display and the printout always indicate the correct units, e.g. when a transmitter is connected.

Conversion between °C (Centigrade) and °F (Fahrenheit) is performed automatically.

Measured value designation

To help identify sensors an alphanumeric designation is also provided (V6 10 characters, D7 up to 20 characters). This name is entered via the interface and will appear in the printout or on the computer display.

Correction of measured values

The measured value on each measuring channel can be corrected both in terms of zero-point and gain; this means that even sensors usually requiring initial adjustment (e.g. expansion, force, pH) can be interchanged freely. Zeropoint correction and, partly at least, gain adjustment can be performed at the touch of a button.

There is also the possibility of performing multi-point adjustment or user-defined linearization.

10 ALMEMO ® 809

Functions of the ALMEMO 809

Scaling

The corrected measured value on each measuring channel can also be further scaled in terms of zero-point and gain based on the base value and factor. The decimal point position can be set by means of the 'Exponent' function. Scaling values can be calculated automatically by setting to zero and entering the nominal setpoint.

Limit values and alarm

Per measuring channel two limit values can be set (one maximum and one minimum). In the event of one of these limit values being infringed relay output modules actuate the associated alarm contacts; these can be allocated individually to specific limit values. Hysteresis is set by default to 10 digits; however, this can be adjusted to any value between 0 and 99 digits. A limit value infringement can also be used to automatically start or stop measured value recording or via macros to control device functions in any way required.

Sensor locking

All sensor data stored in the EEPROM in the plug can be protected - by means of a graduated locking function - against undesired access.

5.1.2 Measuring operation

For nine V6 sensors up to 36 measuring channels are available; i.e. it is thus also possible to evaluate double sensors, individually scaled sensors, and sensors with function channels. All activated V6 measuring channels are continuously scanned at a rate of 10 MOPS (measuring operations per second).

When there are numerous measuring points to consider, the overall response time can be shortened by increasing the measuring rate up to 100 MOPS. A

D7 sensor has up to 10 channels and a sampling rate corresponding to its own individual measuring speed.

Measured values

Measured values are acquired automatically with auto-zero and self-calibration; however, they can also be corrected and scaled individually as required.

With most sensors a sensor breakage is detected automatically.

Analog output and scaling

Each measuring point can be scaled by means of analog start and analog end in such a way that the measuring range thus defined covers the full range of the analog output (2 V, 10 V, or 20 mA). At the analog output the device can output the measured value from any measuring point or a programmed value.

Measuring functions

To achieve optimal measured value acquisition some sensors require certain special measuring functions. Cold junction compensation is provided for thermocouples; temperature compensation is provided for dynamic pressure, pH, and conductivity probes; and atmospheric pressure compensation is provided for humidity, dynamic pressure, and O2 sensors.

ALMEMO ® 809 11

5. Introduction

Measured value smoothing

With V6 sensors measured values of an unstable, fluctuating nature can be smoothed by taking a sliding average over a number of values programmable between 2 and 99. The averaging period will depend on the sampling rate and the number of active channels. However, D7 sensors are assigned their own fixed averaging period for all primary channels; this can be set via the sensor menu.

Maximum and minimum values

Each measuring operation acquires and stores the maximum and minimum values with date and time-of-day. Each of these values can be output, used as function channel, or deleted.

Average value

Manual averaging is available per channel over a particular period or cycle or over a series of individual measuring operations.

5.1.3 Process control

To record the measured values from all connected sensors in digital form measuring point scanning must be performed continuously with measured value output according to a process scheduling system. This may be per output cycle or, if rapid results are required, at the measuring rate itself. Data from each D7 sensor is acquired individually per scan cycle; this can be adjusted to suit the fastest acting sensors, slower acting ones being omitted until new updated values appear.

A measuring operation can be started and stopped by means of a key, the interface, an external trigger signal, the real-time clock, or by a specified limit value infringement.

Date and time-of-day

Each measuring operation can be accurately logged using the real-time clock in terms either of date and time-of-day or purely by actual measuring duration.

For the purposes of starting / stopping a measuring operation the start / stop date and time-of-day and / or the actual measuring duration can be programmed.

Cycle

The output cycle can be programmed to any value between 1 second and 24 hours. This function permits cyclic output of measured values to the interfaces or to the memory and provides cyclic calculation of the average value.

Cycle factor

The cycle factor can be used to restrict data being output from certain channels at the output cycle; this may prove necessary in order to reduce excessive data flow while measured data is being saved. With D7 sensors the individual scan time already set can be changed to a longer preferred scan time.

Averaging over measuring point scans

The measured values from measuring point scans can be averaged either over

12 ALMEMO ® 809

Functions of the ALMEMO 809 the whole fixed measuring period or over the specified cycle. These average values can then be output and saved on a cyclic basis to function channels provided for this purpose.

Conversion rate

The conversion rates available for V5 / V6 sensors are 2.5 / 10 / 50 / 100

MOPS (measuring operations per second). Recording can be accelerated if all measured values are stored to memory and / or output via the interface at the conversion rate. Among D7 sensors there are especially fast models with a scan time of just 1 millisecond, which permits a sampling rate of 1000 MOPS.

Measured value memory

To save measured values there are two alternative methods. The ALMEMO ®

809 incorporates a non-volatile 8-MB flash memory sufficient for up to 1.5 million measured values . This memory can be organized and configured in either linear or ring form. Output is via the interface. Selection can be specified according to date or number.

Or alternatively an external memory connector fitted with a memory card can simply be connected at socket A2. This solution, depending on the size of the card, offers a virtually limitless memory capacity. With an external memory connector, available as an accessory, files can be read out very quickly via any standard card reader.

Numbering of measuring operations

By entering a number single scans or entire series of measuring operations can be identified and selectively read out from memory.

Control outputs

Via the keypad and interface up to ten output relays and up to four analog outputs can be individually addressed.

Output

All data logs, all saved measured values, and all programming parameters can be output to any peripheral equipment. RS232, RS422, USB, and Ethernet interfaces are available via the appropriate interface cables. Wireless communication is also possible via Bluetooth. To accommodate the variable data quantities provided by D7 sensors the interface protocol has been changed so that data is now output in table format only; this can then if so required be processed directly using any standard spreadsheet program.

Networking

All ALMEMO ® devices can be individually addressed and can be networked together by simply linking them up via network cable. However, old V5 / V6 devices and the new V7 devices use different protocols and must therefore be operated via different COM ports.

Software

Each ALMEMO ® Manual is accompanied by the ALMEMO ® Control software package, which can be used to configure the measuring instrument, to pro-

ALMEMO ® 809 13

5. Introduction gram the V6 and D7 sensors, and to read out from the measured value memory. Using the integrated terminal, measuring operations can also be performed online. The WINDOWS ® software package WinControl is provided for measured value acquisition from networked devices, for graphical presentation, and for more complex data processing.

7. Power supply

7. POWER SUPPLY

Power can be supplied to the measuring instrument in any of the following ways : Mains adapter 12 V / 1.0 A

Power supply cable, electr. Isol. (10 to 30 VDC, 0.25 A)

Power supply cable, electr. Isol. (10 to 30 VDC, 1.25 A)

See product overview, Annex 14 and the following chapters.

ZB 1212-NA7

ZB 3090-UK

ZB 3090-UK2

7.1 Mains operation

To power these devices from the mains preferably use the mains adapter provided (for type see above); connect it to the socket DC (7).

7.2 External DC voltage supply

The DC socket (7) can also be used to connect another DC voltage, 9 to 13 V

(minimum 200 mA). For this connection use a cable with 2 banana plugs (ZB

5090-EK). If, however, the power supply has to be electrically isolated from the transducers or if a larger input voltage range (10 to 30 V) is required, then an electrically isolated supply cable must be used (ZB 3090-UK). It will then be possible to use the measuring instrument in a 12-volt or 24-volt on-board supply system.

7.3 Sensor supply

An den Klemmen – und + im ALMEMO ® -Stecker steht bei Netzbetrieb eine

Fühlerversorgungsspannung von 12V (400mA) zur Verfügung (selbstheilende

Sicherung 500 mA). Andere Spannungen (12V, 15V, 24V oder Referenzen für

Potentiometer und Dehnungsmessstreifen) sind mit speziellen Steckern erreichbar (s. Hb. 4.2.5/6).

7.4 Switching ON / OFF, reinitialization

To switch the device ON / OFF press the ON / OFF key (2).

To switch the device OFF press the ON / OFF key and hold down for approx. 1 second. After the device is switched off the real-time clock continues to run and all saved values and settings are retained intact.

If interference (e.g. electrostatic or mains failure) causes the device to behave abnormally, you are advised first of all to try clearing the problem by simply reinitializing, i.e. switching off and then on again.

If this does not help then you are advised to restore all device programming to the factory default settings. The device can be reset by setting the code switch G (1) , before switching on, to address 99. The device name, device programming with all settings, memory and macros are deleted and the baud rate setting in the data cable is reset to 9600 baud. Only the time, device calibration and programming of the sensors in the ALMEMO ® connectors remain unaffected.

16 ALMEMO ® 809

Data buffering

7.5 Data buffering

The sensor's programming is stored in the EEPROM on the sensor plug; the device's calibration and programmed parameters are stored in the EEPROM on the device itself; both are fail-safe. The memory data is also saved in nonvolatile EEPROMs. Date and time-of-day are buffered by a dedicated lithium battery; this data is retained intact for years - even when the device is switched off and without batteries.

8. CONNECTING SENSORS / TRANSDUCERS

Virtually any ALMEMO ® sensor can be connected to any of the input sockets

M0 to M8 on the ALMEMO ® measuring instrument (1); (this includes all standard V5 and V6 sensors and newer D6 and D7 digital sensors). The ALME-

MO ® Manual includes detailed descriptions of the comprehensive ALMEMO ® range of sensors (see Manual Ch. 3) and instructions for connecting your own existing sensors to ALMEMO ® instruments (see Manual Ch. 4). To connect your own existing sensors you simply need the appropriate ALMEMO ® plug.

All standard sensors with an ALMEMO ® plug usually have the measuring quantity, range, and units already programmed and can thus be connected to any input socket without further adjustment. A mechanical coding system ensures that sensors and output modules can only be connected to the correct sockets.

All ALMEMO ® plugs incorporate two snap-lock levers; these snap into position as soon as the plug is inserted into the socket, thus preventing unintended disconnection if the cable is pulled accidentally. To withdraw the plug these two levers must first be pressed in at the sides.

8.1 Standard sensors (V5,V6)

Standard ALMEMO ® V6 sensors are housed in a light-gray case. The exclusive source of their intelligence is a 4-KB EEPROM (E4) integrated in the sensor plug, in which all channel settings are stored; the device is thus programmed completely as soon as any such sensor is connected. These sensors also support multi-point calibration. Older sensors (V5) with an EEPROM of only 2

KB do not yet support this feature. Passive analog sensors are electrically isolated from one another by means of photovoltaic relays; all signals in the device are converted analog-to-digital.

Digital sensors used for the quantities - frequency, pulse, or DIGI - incorporate a microcontroller, which transfers digital signals to the device via an I 2 C bus.

Measured values are processed in synchrony with the conversion rate (maximum 100 MOPS) and at a resolution of maximum ±65000 all in the device including linearization and various forms of compensation.

ALMEMO ® 809 17

8. Connecting sensors / transducers

8.2 D6 sensors

ALMEMO ® D6 sensors are housed in a partly light-gray, partly dark-gray case; they are completely autonomous measuring modules not only for digital but also for analog sensors; they can, independently of the device, handle new measuring quantities and ranges with special measured value processing and various forms of compensation. As regards measured value processing D6 sensors are fully compatible with standard sensors - except for multi-point calibration and smoothing; however, quantity and range configuration and parametrization must be performed via the special 'Sensor configuration' menu in the

ALMEMO ® Control software either on the V7 device itself or, using a USB adapter cable, directly on the PC.

(see additional instructions 'Digital ALMEMO ® D6 sensors').

8.3 D7 sensors

ALMEMO ® D7 sensors are housed in a dark-red case; they too are completely autonomous measuring modules for digital and for analog sensors - but offer substantially enhanced properties. The conversion rate can be set from 1 millisecond up to several minutes with a resolution up to 8 digits. The number of channels has, thanks to a new numbering scheme, been extended up to 10 per sensor and up to 10000 per device. Channel designations can be up to 20 characters and units up to six characters in length. With D7 sensors up to four primary channels can also be smoothed at the same time internally over the averaging period. For the purpose of setting individual parameters (e.g. quantities and ranges, averaging period) special menu 'Sensor configuration' is provided by the sensor itself. (see additional instructions 'Digital ALMEMO ® D7 sensors') All measured value processing is performed in the sensor itself; the resulting data is transferred no longer via an I2C bus but via the serial interface alone. For this reason and because of the expanded data format D7 sensors can only be operated in conjunction with a V7 device or directly on a PC. For

D7 sensors dedicated extension cables and an adapter cable for electrical isolation are available.

Measuring inputs , additional channels

8.4 Measuring inputs , additional channels

Measuring instrument ALMEMO ® 809 incorporates nine input sockets M0 to

M8 (1); to these, under the new channel numbering scheme, measuring channels M0.0 to M8.0 are initially assigned. Whereas standard sensors can if necessary provide up to four channels (M0.0 to M0.3, M1.0 to M1.3, etc.), D7 sensors can provide up to 10 (M0.0 to M0.9, M1.0 to M1.9, etc.). The additional channels can be used in particular for humidity sensors with numerous measurable variables (temperature / humidity / dewpoint / mixture ratio) or for function channels. Each sensor can if necessary be programmed with several quantities or scaling settings; and two or three sensors, if pin assignment so allows, can be combined in a single plug (e.g. RH / NTC, mV / V, mA / V, etc.).

This device does not incorporate any internal channels.

On the measuring instrument this gives the following channel assignment:

8.5 Potential separation

When organizing a properly functioning measuring setup it is very important to ensure that no equalizing current can flow between sensors, power supply, and peripherals. All measuring points must therefore either be insulated (e.g. by air spacing) or lie at the same potential - and any unequal potentials that do exist must be electrically isolated.

The nine analog inputs on this device are electrically isolated from one another by means of photovoltaic relays. A new feature is the additional separation of the measuring inputs from the CPU and power supply. However, for some analog sensors this electrical isolation may have to be disabled again by means of relay S (see above) or a wire jumper; some inputs would otherwise be left without reference potential. The first time any such sensor is connected this relay is set automatically by means of element flag 5 ' ISO OFF '. (see Man. 6.10.3)

However, with certain connectors (e.g. divider connectors without power supply) element flag 5 should be checked and if necessary corrected. Between all inputs and outputs (even those analog output cables not electrically isolated) the maximum potential difference permitted is 50 V. The voltage at the measu-

However, some components are not electrically isolated , namely all sensors connected to the common internal power supply ±U and sensors combined within one connector. This also includes all D7 sensors; each such sensor

(in particular electrical measuring connectors) must therefore be used with a small adapter cable ZA D700-GT; this provides electrical isolation for the power supply and data lines. Such problems do not affect sensors without a conductive connection. Non-insulated sensors can be sufficiently protected by electrically isolating the power supply (battery, mains adapter, or connecting cable with DC/DC converter).

Data and trigger cables are also insulated by means of optocouplers.

Operation and configuration

9. OPERATION AND CONFIGURATION

Measured data acquisition module ALMEMO ® controls; it is operated mainly via a PC.

809 has only a few operating

9.1 Combination key

The first function of the one and only key ON/OFF - START/STOP (2) has already been described in Section 6.5.

Press to switch the device ON and press and hold down to switch OFF again.

If the device is on and a cycle has been programmed the same key can be used to start and stop a measuring operation.

The current operating status is clearly shown by the status LEDs.

9.2 Status LEDs

The status LEDs (3) report the current device status as follows:

ON Device is switched ON

ON flashes briefly just once Device is in sleep mode

START is lit continuously

COM is lit continuously

COM flashes

REC is lit continuously

Cyclic measuring has started

Measured values are transmitted to the PC-per output cycle

Measured values are transmitted to the PC - per scan cycle

Data is being saved to device memory per cycle.

This also lights up during output from memory.

REC flashes Data is being saved to memory per scan cycle

START flashes briefly just once Once-only measuring point scan is initiated by the PC

COM flashes briefly just once Once-only measuring point scan transmits data to the PC

REC flashes briefly just once Once-only meas. point scan saves data to device memory

ALARM

ALARM flashes

Limit value infringement or sensor breakage

Supply voltage to device is too low

9.3 Device address and networking

The ALMEMO ® 809 data logger, like all ALMEMO ® devices, can also be networked. To communicate with networked devices it is absolutely essential that each device should have its own dedicated address; this is because only one device should respond per command. Before each network operation therefore all measuring instruments must be set, by means of their code switches (1), to different device numbers.

Example: Module address 01 0 1

ALMEMO ® 809 21

9. Operation and configuration

 In network operation consecutive numbers between 01 and 99 should be used; this ensures that device 00 is not addressed unnecessarily in the event of interruption to the power supply.

9.4 Configuration, new V7 functions

For the purposes of programming and configuration the supplied ALMEMO ®

Control software is ideally suited. This can be used to modify the sensor programming and to configure the process control. The various possibilities are explained in detail in the Manual, Section 6.8. This also describes how all functions can be programmed using ASCII commands via a terminal.

New V7 functions

This section lists all the new V7 functions not supported by V6 devices. Most such functions are only supported in conjunction with D7 sensors.

1. The new channel numbering scheme has already been described in detail in Chapter 8.4; this applies to all sensors. Channel numbers are now entered with a decimal point; the range of channel numbers available goes up to 999.9. Channels are now scanned per sensor; this improves the consistency of measured values.

2. The use of autonomous digital D7 sensors which provide measured values themselves in parallel and in full allows a much higher but also variable measuring speed . With D7 sensors the individual scan time (minimum 1 ms) can be changed to a freely selectable longer preferred scan time. The process of scanning and output of data to memory or an interface is performed in less than one millisecond per channel. To achieve this speed a new scan cycle has been introduced; this operates in the range of 1 millisecond up to 99 seconds and can only be used to monitor the maximum, minimum, and limit values or to output to interface or memory. It is controlled (as previously) by means of the sampling rate output flags 'save-to-memory continuous' and 'output continuous'.

To help the user choose the most suitable scanning rate the following table is provided.

Minimum time Scan time for the fastest sensors

Conversion time Time for A/D converter per V6 channel

Scan time Time for A/D converter for all V6 channels

Maximum time Scan time for the slowest sensors

The most suitable scanning rate generally for all sensors is 'minimum time'.

What is special about this scan setting is that data from both high-speed and low-speed sensors can be acquired together without generating large quantities of superfluous junk data. Slow D7 or V6 sensors are simply omitted until a new measured value is detected.

To obtain up-to-date values the scan cycle can of course be programmed

22 ALMEMO ® 809

Configuration, new V7 functions to any setting - but preferably to a multiple of the high-speed sensors.

Time-stamp resolution will depend on the scan cycle selected.

3. The autonomous D7 sensors can now handle a measured value volume up to 8 digits plus arithmetic sign. They can also handle text, time-of-day, and coordinates. Output to an interface or to memory is now only supported therefore in the form of an ASCII string and in table format.

There is thus no longer a choice between various output formats.

4. Each D7 sensor normally has its own digital measuring quantity and range but this can be selected via the V7 measuring instrument. The quantity abbreviation has been extended to six characters. Functions for controlling the measuring sequence or for measured value compensation are performed in the sensor itself and the sensor itself, similarly, provides a menu for configuring any necessary individual parameters.

5. With D7 sensors the units and comments text have been adapted to meet rising demands; they have been extended, units to 6 and comments text to

20 characters.

6. With V6 devices the smoothing of unstable measured values by taking a sliding average could be performed on the selected measuring channel only. Most D7 sensors provide this function for up to four primary channels. This can be set, similarly, via the afore-mentioned sensor menu. (see

D7 sensor instructions).

10. MEASURED DATA ACQUISITION

Measured data acquisition can be performed in basically two ways.

1. Perform measuring operation online; data is transferred to the PC immediately (no device-internal memory is required).

2. Perform measuring operation offline; data is first saved to the device’s internal memory or to an external memory connector with a micro SD card and then transferred to the PC later.

10.1 Online measurement with PC

For conveniently recording measured data directly on the PC our WinControl measured value acquisition software is ideally suited. This software is unique in that it can scan one stand-alone or several internetworked measuring modules each at its own measuring cycle, then save the measured data on the PC, and output it online in a clearly understandable form as a line diagram, table, or list of individual measured values; thus for process control purposes you need simply program each measuring cycle in WinControl. There are numerous other possibilities using formula channels, control and regulation functions, alarm reports via SMS and e-mail, etc. but it would be going too far to describe all these here in detail.

ALMEMO ® 809 23

10. Measured data acquisition

10.2 Offline measurement

For offline measuring operations, i.e. data logging in the device itself, either the device's own 8-MB flash memory or an external memory connector with a micro SD card must be used.

It is an indispensable prerequisite that the following parameters be configured :

1. Date, time-of-day

2. Cycle or scan cycle with saving to memory activated

3. Sleep mode, possibly

The easiest way to do this is by means of our ALMEMO ® Control software, in menu <Program device> and <Measured value memory - Save to memory>.

To start and stop a measuring operation on site there are numerous methods available. (see Man. 6.6)

1. Press the START / STOP key (2) on the device.

2. Program the start date and time-of-day and then either the end date and time-of-day or the fixed measuring period. (see Man. 6.6.2)

3. Reaction in the event of a limit value being overshot or undershot ( see Man.6.6.3

)

4. Triggering in response to electrical signals (see Man. 6.6.4)

The status of a measuring operation and of data recording can easily be traced by watching the LEDs. (see 9.2)

To read out the measured data select ALMEMO ® Control menu item <Devices - Measured value memory>. (see Man. 6.9.3) Here you can transfer to a file on the PC either the complete memory or parts of it selected according to date or by number; the device memory can then be cleared.

10.2.1 Sleep mode

For long-term monitoring involving long measuring cycles where power is supplied by rechargeable or normal battery the measuring instrument can also be operated in sleep mode. In energy-saving sleep mode the measuring instrument switches off after each measuring point scan and switches on again automatically after the cycle expires ready for the next measuring point scan. In this way, with just one battery recharge, it is possible to perform up to 30,000 measuring point scans; with a cycle lasting 5 minutes this represents a total runtime of over 100 days.

For data recording in sleep mode go to ALMEMO ming> and take the following steps:

1. Enter a cycle lasting at least two minutes.

2. Activate saving to memory in the cycle.

® Control <Device program-

3. Switch sleep mode on.

4. Start measuring operation as normal; the device should then switch off automatically; as a check the LED 'ON' (3) should flash rhythmically on and off.

24 ALMEMO ® 809

Offline measurement

6. In the specified cycle the device switches on automatically, performs one measuring point scan, and then switches off again.

7. To stop the measuring operation press key (2) twice, Function ´ ON ´ and

´ STOP ´.

In this way any number of measuring operations can be performed in sleep mode up until when sleep mode is deactivated again. With cycles shorter than two minutes measuring operations are performed automatically in normal mode.

10.2.2 Measured value memory, internal

Measured data acquisition module ALMEMO ® 809 incorporates an 8-MB flash memory, sufficient for up to 1,600,000 measured values (depending on the number of channels and measured value volume). This memory is non-volatile; i.e. it retains data intact even in the event of a failure affecting the lithium battery used to buffer the real-time clock. The system for organizing the measured value memory has been changed; measured values are now saved in

ASCII and in table format (similar to the system used for interface output).

When a connector's configuration is modified the new configuration is now saved and, if the linear memory mode has been selected, is assigned a number

(similar to the system used for the memory card) . These 'files' can be individually selected and output. The ring memory mode remains an available alternative. (see Man. 6.10.13.2) However, if the ring memory mode has been selected, the connector configuration cannot be changed.

The following functions are supported by the internal memory:

- Linear memory mode - multiple connector configurations can be saved.

- Ring memory mode - only one connector configurations can be saved.

- Sleep mode

- Data is output in table format only.

- Selective data output by date only

- Selective data output by number

10.2.3 Memory connector with SD memory card

Another convenient method for data recording is memory connector ZA 1904-

SD with a conventional micro SD memory card. Measured data is written to the memory card via the plug-in memory connector; this data is saved in standard FAT16 table format. The memory card can be formatted and its contents can be read out and / or deleted on any normal PC using any standard card reader. (see Manual, 6.9.4.2) This data can also be imported into MS-Excel or into WinControl. The memory connector works in a completely different way to the device-internal memory; this brings with it not only restrictions but also new advantages.

Memory connector functions

- Virtually unlimited memory capacity

- With each new connector configuration a new file is created.

ALMEMO ® 809 25

10. Measured data acquisition

- Ring memory mode is not supported.

- Sleep mode

- Data can be evaluated using any reader on site or anywhere else.

- Very fast data transfer via the reader

- Data recording and output in table format only

- On the ALMEMO ® device itself only the last file can be read.

- Selective data output according to date and time-of-day or by number code is not supported

The memory connector with the memory card can be connected at socket A2; it will be recognized automatically. If at the start of any measuring operation an external memory has been connected, it will be used. In the course of a measuring operation the external memory must not be unplugged; all temporarily buffered measured values would be lost.

Before starting any measuring operation you can enter an 8-character file name. (see Ch. 11) In the absence of a user-defined file name, the default 'AL-

MEMO.001' or the name most recently used will be suggested automatically.

So long as the connector configuration is not altered, any number of measuring operations can be saved - either manually or cyclically, also with number codes, all in the same file.

If, however, the connector configuration has been changed since the last measuring operation, a new file will be created; and, if no new file name has been programmed, the index in the file name extension will automatically be incremented by 1, e.g. ' ALMEMO.002

'. Similarly, if the file name now entered already exists, a new file will be created with the same file name prefix but with a new index.

11. SPECIAL MEASURED QUANTITIES, LINEARIZATION,

MULTI-POINT CALIBRATION

Thanks to the new ALMEMO with a certain elegance.

® V6 connectors with extra memory for additional data (bigger EEPROM, code E4) the following tasks can now be performed

1. Provision of special measuring quantities with internal characteristic

2. User-defined linearization of linear signals for voltage, current, resistance, or frequency

3. Multi-point calibration of all sensors

4. Serial number and calibration data management in the sensor

The ALMEMO ® 809 can as standard evaluate all appropriately programmed special connectors. With option KL it is also possible to convert measuring signals into equivalent display values based on a characteristic of up to 35 interpolated values. These control points can be programmed and saved in the EE-

PROM in the ALMEMO ® connector using the ALMEMO ® Control software

(menu <Measuring points> list <Program measuring point>, <Measuring point>, multi-point calibration / special linearization). During a measuring opera-

26 ALMEMO ® 809

Special measured quantities, Linearization, Multi-point calibration tion the measured values between these points are interpolated on a linear basis. When correcting non-linear sensors (e.g. with Pt100 or thermocouple sensors) initially the original characteristic is considered; and only then are the deviations interpolated on a linear basis and inserted.

If a channel with a characteristic is deactivated or programmed with a different quantity, the characteristic can subsequently be reactivated by restoring the special quantity using command 'B99'.

Other information that can be entered in the extended connector includes the order number, the serial number, the date of the next calibration, and the calibration interval. In networked systems the calibration intervals can thus be monitored automatically.

12. TROUBLE-SHOOTING

The ALMEMO ® 809 measured data acquisition module can be configured and programmed in many different ways. This system is suitable for connecting a wide variety of very different sensors, additional measuring instruments, alarm signaling devices, and peripheral equipment. Given these numerous possibilities the device may in certain circumstances not behave quite as expected.

The cause of such unexpected behavior is not usually a device defect; often the cause is incorrect operation by the user, an invalid setting, or unsuitable cabling. In such event try to pinpoint and clear the problem with the aid of the following tests.

Error: No or all LEDs light up; keys do not react.

Remedy Check the power supply; charge the battery; switch off and then on again; if necessary re-initialize (see 7.4)

Error Measured values are incorrect.

Remedy Check all the channel programming very carefully, especially the base value and zero-point (sensor programming and special functions).

Error Measured values fluctuate unexpectedly or the system hangs in midoperation.

Remedy Check the cabling for any inadmissible electrical connections. For sensors with their own integrated power supply check element flag 5.

see 8.5 Unplug any suspicious sensors. In its place connect a handheld sensor in air or phantom mode (for thermocouples short-circuit

A-B, for Pt100 sensors use 100Ω resistor) and check. Connect the sensors again one at a time and check successively. If a fault persists for any one connection, check all wiring; if necessary, insulate the sensor and eliminate interference by using shielded or twisted wiring.

Error Data transmission via the interface does not function.

ALMEMO ® 809 27

12. Trouble-shooting

Remedy Check the interface module, connections, and settings. Ensure that both devices are set to the same baud rate and transmission mode.

(see Manual, 6.10.12) A reset with the interface module connected will set the baud rate to 9600 baud. (see 7.4) Ensure that the correct

COM port on the computer is being addressed. Is a printer in the ON-

LINE status ? Test data transmission by means of a terminal (ALME-

MO ® Control, WinControl, WINDOWS Terminal). Address the device using its assigned device number ' Gxy '. (see Man. 6.2.1) If the device is in the XOFF status, enter <ctrl Q> for XON. Check the programming by means of ' P15 '. (see Man. 6.2.3) Test the transmit line only by entering the start command 'S2'; the LED START should light up.

Test the receive line only by pressing the START / STOP key.

Error Data transmission in the network does not function.

Remedy Check to ensure that all devices are assigned different addresses.

Address all devices individually via the terminal using command ' Gxy '.

Addressed device is OK if at least 'y CR LF' is returned as echo. If transmission is still not possible, unplug the networked devices.

Check all devices individually on the data cable to the computer.

(see above) Check the wiring for short-circuit or crossed wires. Ensure that all network distributors are supplied with power. Network the devices again one after the other and check successively. (see above)

If, after performing the above-listed checks and remedial steps, a device still fails to behave as described in the operating instructions, it must be returned to our factory in Holzkirchen, accompanied by a brief explanatory note, error description, and if available test printouts. With the ALMEMO you can print out screenshots showing the relevant programming details and save and / or print out a comprehensive 'function test' in the device list or terminal mode.

® Control software

13. ELECTROMAGNETIC COMPATIBILITY

The following advisory notes must be observed when operating the device.

If the standard sensor is extended (1.5 meters) care must be taken to ensure that the measuring lines are not laid together with high-voltage power cables and that, if necessary, they are properly shielded so as to prevent spurious interference being induced in the system.
