4.3 Short description

The DL230 data logger is used to determine maximum load and to register load profiles in gas plants for special-rate clients. Up to four meters or lowfrequency pulse outputs from volume correctors can be connected to the data logger. This means that the device is suitable for plants with more than one measurement. Two of the input channels can also alternatively be connected to encoder counters. Inputs which do not capture consumption information or original meter readings can also be parameterized as status inputs.

1 2 3 4 5 6 7

Construction and Function 33

Simple monitoring functions are possible with this. Events can be stored in an archive, emitted as a status signal or transmitted to a central location via SMS if required. Two digital outputs can be used to transfer consumption information or to signal warnings and alarms. Energy supply is with lithium batteries. In addition, the device can also be equipped with a 230VAC power supply unit. For data communication purposes an integrated modem is available, which supports the GSM, GPRS and UMTS (2G and 3G) radio standards. Alternatively, communication modules can be used for Ethernet communication or for communication via RS232/RS485 interface. Use of the DL230 is via 7 keys and an alphanumeric display on the front panel.

4.4 Connections

The DL230 memory can be connected to: – a maximum of three batteries (2x device batteries and 1x modem bat-

tery or 1x device battery and 2x modem batteries)

– Optional 230V connection to an internal power supply unit The following can be used to monitor and record data and to transmit data and program functions:

– 4 counting and signal inputs DE1, DE2, DE3, DE4 – 2 pulse and signal outputs DA1, DA2 – Integrated GSM/GPRS modem – Optical data interface

Further details on the connection possibilities for the DL230 and the available equipment versions can be found in the "Technical Data" chapter and in chapter "Assembly, Connection and Putting into Operation".

Assembly, Connection and Putting into Operation 37

5.2 Connection

The DL230 is available as officially calibrated or a factory calibrated device. Information regarding additional equipment versions of the DL230 can be found under www.elsterinstromet.com.

DANGER! The connection of non-intrinsically-safe or nonassociated apparatus presents a risk of explosion!

The operation of the DL230 as associated apparatus for zone 0 or 1 and the connection of non-intrinsically-safe equipment which exceeds those conditions and limit values specified in the declaration of conformity, presents a risk of explosion.

Therefore: – When the DL230 is used as associated apparatus only

devices with intrinsically-safe circuits and electrical data that corresponds to those requirements stipulated in the declaration of conformity for the DL230 (see Appendix), should be connected.

– When connecting the DL230 and putting it into operation, the guide-

lines of the corresponding EN 60079-0 and EN 60079-14 standards should be observed.

– The wiring of the connections should be professionally carried out by a

gas specialist or a calibration officer.

– Active outputs cannot be switched. – Connect unused cable glands as per EN 60079-14 with the help of a

plug or a suitable screw cap. To program the device and carry out further applications the optical interface of the DL230 (see the "Construction and Function" chapter) can be used. Further details can be found under www.elster-instromet.com.

The connections described below should only be sealed by a calibration officer. If the DL230 is used for operations, which are not subject to calibration regulations, the seals on the respective connections can be omitted.

38 Assembly, Connection and Putting into Operation

5.2.1 Connecting meters

For the purpose of measuring consumption the pulse transducers from up to four meters can be connected to the DE1 to DE4 digital inputs of the DL230. Alternatively, encoders can be connected to inputs DE1 and DE2.

III. 8

Further details and special features regarding the use of the pulse transducer and encoder are described in the following subchapters.

The wire cross-section for the connection to the DL230

inputs is 0.3 … 2.5 mm

When using stranded wire, use appropriate wire ferrules.

Use only cables, which fit to the cable glands in order to keep IP protection class also after the installation. Minimum cable diameter: Cable gland M12 ≥ 5 mm Cable gland M16 ≥ 5,5 mm.

5.2.1.1 Connection to a pulse transducer

1. Connect the meter's pulse transducers to the DE1 to DE4 terminals (III.

8) of the DL230. The polarity can be freely selected (the symbols "+" and "-" on the terminals are used for the connection of other pulse transducers or encoders).

2. Adjust the measurement parameters, e.g. the cp value (pulse constant), as described in chapter 5.3.1.2.

5.2.1.2 Connection to an encoder

1. Connect the meter's encoder(s) to the DE1 and DE2 terminals (III. 8) of the DL230. The polarity should be taken into consideration, i.e. connect the "+" of the encoder to the "DE1 +" terminal and "-" to the "DE1 -" terminal respectively.

2. Adjust the measurement parameters, e.g. the encoder type, as described in chapter 5.3.1.3.

Assembly, Connection and Putting into Operation 39

5.2.2 Sealing the input terminals

After connecting to the meter as per chapter 5.2.1 the respective DE1 to DE4 input terminal must be sealed for official calibration measurements. For this purpose, terminal covers are provided in the bag of accessories. If required, these should be screwed over the connected terminals and an adhesive seal should then be bonded to the fastening screw (see chapter

5.3.2).

5.2.3 Connecting the power supply

5.2.3.1 Power supply for the DL230 with integrated power supply unit

DANGER! Danger to life from electrical current!

Touching live parts poses an imminent danger to life. Therefore: – Works on the electrical components of the device, i.e.

the connection of the power supply unit, should solely be carried out by qualified electricians.

– When performing all works to the electrical system,

switch off the power, secure it against an accidental restart and check to ensure that the voltage has been cut.

– Keep moisture from live parts away. This could lead to

short-circuit.

The power supply unit to connect the 230 V~ power supply, is in-built into the base of the DL230.

III. 9

1. Switch off the supply voltage and secure it against an accidental restart!

2. Connect the 230V~ supply voltage to the terminal block ( 1 ) of the power supply. Terminal "PE" is the connection for the protective conductor (protective earthing).

40 Assembly, Connection and Putting into Operation

The wire cross-section for the connection to the integrated

power supply unit is 0.3 … 2.5 mm

When using stranded wire, use appropriate wire ferrules.

Use only cables, which fit to the cable glands in order to keep IP protection class also after the installation. Minimum cable diameter:

Cable gland M12 ≥ 5 mm Cable gland M16 ≥ 5,5 mm.

DANGER! Danger to life from electrical current!

Connect the protective earthing of the mains power supply to the J2 screw terminal, connection "E"!

5.2.4 Connect outputs of the DL230

DANGER! The connection of non-intrinsically-safe or nonassociated apparatus presents a risk of explosion!

Therefore: – When the DL230 is used as associated apparatus only

devices with intrinsically-safe circuits and electrical data that corresponds to those requirements stipulated in the ATEX declaration for the DL230 (see Appendix), should be connected. Notice also the limitations of chapter 3.6.1.

– Screw the terminal covers over the connected output

terminals again.

The wire cross-section for the connection to the DL230 out-

puts is 0.3 … 2.5 mm

When using stranded wire, use appropriate wire ferrules.

Assembly, Connection and Putting into Operation 41

Use only cables, which fit to the cable glands in order to keep IP protection class also after the installation. Minimum cable diameter: Cable gland M12 ≥ 5 mm Cable gland M16 ≥ 5,5 mm.

Different downstream devices can be connected to the digital outputs of the DL230. The outputs are preconfigured for this purpose (see chapter 5.3.1.5).

Ill.: 10

1. Remove the terminal cover for the digital

outputs (terminals DA1 and / or DA2) (Ill.: 10).

2. Connect the downstream device to the

corresponding digital outputs (terminals DA1 to DA2) of the DL230 (Ill.: 10).

3. Screw the terminal covers over the connected

terminals after connecting the cables. If required, a seal should then be bonded to the fastening screw (see chapter 5.3.2).

4. If necessary, adjust the cp value (pulse

contact) for the pulse outputs as described in chapter 5.3.1.5.

5.2.4.1 Electrical insulation of the outputs

In standard cases, all negative poles of the outputs are electrically connected to the motherboard. For special applications, i.e. switching a positive pole, each output can be electrically separated from the motherboard and from the other outputs.

CAUTION! Reduced battery life

Activation of electrical isolation of outputs reduces battery life when operating the battery.

It is then impossible to give a reliable prediction of the remaining battery life.

42 Assembly, Connection and Putting into Operation

An electrically-insulated output only requires electricity if the output is active (switched-on). You can therefore minimize the negative influence of an electrically-insulated output on the battery life by setting the pulse duration to the lowest possible value when using it as a pulse output.

The configuration software "enSuite" is suitable for this purpose.

The electrical insulation of the outputs is not an approved electrical isolation in accordance with ATEX. An approved Exisolator is required when using the device as associated apparatus in Ex zone 0 or 1.

In order to activate the electrical insulation of an output, move the switch lever behind the corresponding output terminal away from the terminal:

Ill.: 11

Switch for electrical isolation

Output DA2 is electrically isolated (the slider on the switch is up)

Output DA1 is not electrically isolated (the slider on the switch is down)

Serv.  Input 1  Parameter settings  HTLT1

or Serv.  Input 2  Parameter settings  HTLT2 or Serv.  Input 3  Parameter settings  HTLT3 or Serv.  Input 4  Parameter settings  HTLT4

If the displayed value is "-.-.-", then no switch over took place. If the value is not equal to "-.-.-", then a switch over to the set event is taking place. In principle two settings are possible: a) Meter 1 counts, meter 2 does not b) Meter 1 counts at high tariff (HT) and meter 2 at low tariff (LT)

In case b) the switch over between HT and LT should be parameterized via a settings file. Switch over either takes place in a "time-dependent" manner or "controlled by an input". With the inactive meter, the short description will be shown flashing.

Adjustment is simple to carry out via enSuite configuration software.

Parameterization of the device is described in the DL230 application manual.

For data protection reasons, reading values from the interfaces is only possible if at least one of the locks is open.

Operation 61

6.3.6.1 Calibration lock

The calibration lock is used to protect parameters subject to calibration regulations. This includes all values, which influence volume readings. The calibration lock is designed as a button, which is positioned inside the DL230 housing underneath the circuit board cover. It can be protected with an adhesive label (see chapter 5.3.1.1, "Opening the calibration lock"). The calibration lock is opened by pressing the button ("P" symbol flashes in the display) and is closed again by pressing the same button ("P" symbol fades). It can also be closed by deleting the value "St.PL" (see chapter

6.4.6, "Ctrl." register (control)) via the keyboard or interface. Using the configuration software "enSuite", a time can also be set (in minutes) after which the calibration lock will automatically close. The level of protection can be changed for all parameters upon request, particularly for applications, which are not subject to German calibration guidelines. For example, parameters, which are protected by the calibration lock as standard, can also be protected with an administrator's lock or a certification data log.

6.3.6.2 Certification Data Log

The certification data log is activated as standard but can also be disabled. The corresponding parameters will then be protected by the calibration lock. Using the "certification data log" as per PTB-A 50.7, several parameters subject to calibration regulations can also be adjusted when the calibration lock is closed. This is subject to the following conditions:

• The administrator's lock (see below) must be open.

• There are at least three free entries in the certification data log.

The following parameters are set as default:

• "Md.I1" to "Md.I4" modes for inputs 1 to 4

• "V1" to "V4" Main counter for inputs 1 to 4

• "cp.I1" to "cp.I4" cp values for inputs 1 to 4

• "MP.I1" to "MP.I4" measurement periods for inputs 1 to 4

• "TG.I1" to "TG.I4" daily limits for inputs 1 to 4

• "Clr.A" delete measurement archive

• "HTLT1“ to "HTLT4" settings for HTLT conversion

For every change of a parameter listed under "PL" when the calibration lock is closed, one row of data will be entered for the value before and after the change. If the certification data log is full, it can be deleted using the command "ClCDL" if the calibration lock is open (see chapter 5.3.1.8).

62 Operation

If the calibration lock is opened when the certification data log is full, it can only be closed again after the calibration log has been deleted.

6.3.6.3 Administrator and customer locks

Administrator and customer locks are used to protect data which is not subject to calibration regulations, but which should also not be modified without authorization. These locks can be opened by entering a code (i.e. the "key") under Cod.A or Cod.C and are closed by entering "0" for St.AL or St.CL. These values can be found under the following path:

6.5 Use as high-flow display device

The DL230 has an integrated high-load display function and has national approval. The following consumption figures are calculated and stored for each of the four inputs along with timestamps and can be shown on the device when requested:

- the load registered during the current measurement period (VxMPc)

- the load registered during the previous measurement period (VxMPL)

- the highest load registered within a measurement period within the current

month (VxMPc)

- the load registered during the current day (VxDGc)

- the load registered during the previous day (VxDGL)

- the highest daily load registered during the current month (VxDGc)

The measurement period maximum (VxMPL) and the daily maximum (VxDGL) of the last 15 months are stored in the monthly archive of the respective input. The content of this archive can be found under: Admin  Input x  Monthly Archive Ix

Operation 71

The resulting maximum values of the current month can be found under:

Admin  Input x  per measuring period and under: Admin  Input x  per day

At the end of each month the "resulting maximum values" of the month just gone are written into the newest data record of the monthly archive. At the same time, the oldest data record is deleted so that the monthly archive always covers 15 months at most.

The end of the month can be parameterized separately for each input and takes place at an adjustable time on the first day of each month. This monthly limit (=daily limit) is set to 6:00 AM as a default setting.

The daily limit (DG.Ix) can be found under the following path: Admin  Input x  per day

If at least two entries are still free in the certification data dog then it is possible to change the daily limit when the administrator lock is open. Otherwise, the value can only be changed when the calibration lock is open. All full hours of the day (0:00 to 23:00) can be set.

7.2.3 Display remaining battery power

The calculation of the remaining battery power depends on the

consumed capacity (which is measured) and on the

anticipated future consumption under typical conditions. These

two values lead to the theoretical remaining battery power,

which is displayed under Bat.R. For applications with atypical

high power consumption, this procedure may cause the actual

remaining battery power to drop quicker than the displayed

predicted remaining battery power.

The remaining battery power Bat.R will automatically be

recalculated after entering a new battery capacity Bat.C (see

above). The Bat.R value cannot be edited.

◼ Move the cursor to the "Admin" register and to the "Bat.R" value (re-

maining battery power) via the following path:
