Electronic index EI for diaphragm gas meters BK-G...B

The electronic index EI3 indicates the volume at base

conditions. It can be used for reading out absolute consumption values and for retrieving consumption data for the various tariffs.

This function is only guaranteed when used within the

speciﬁed limits – see page14 (Technical data). Any other use is considered as non-compliant.

Replacing the communication module

WARNING

Risk of explosion in explosion-hazard areas!

– As a general rule, maintenance and repair work

should be avoided in explosive atmospheres.

– Check that the electrical system complies with

the special electrical explosion protection requirements.

– When working on electrical equipment in an

explosion-hazard area, only design-approved electrical operating equipment may be used.

– Use original spare parts supplied by Elster

GmbH, see page 14 (Spare parts).

▷ When changing the SIM card together with the

communication module or just exchanging the SIM card, the optical communications link has to be established, see page 8 (Establishing an optical communications link).

▷

For safe handling in an explosion-hazard area, the order of the following steps has to be ensured.

Changing the SIM card

 Establish the optical communications link, see

page 8 (Establishing an optical communications link).

 Follow steps 1 to 6 of “Replacing the commu-

nication module”, see section above.

▷

The SIM card slot can be found on the underside

of the module.

 Brieﬂy press the SIM card to remove it from the

holder.

4 Insert the new SIM card in the same position

and lock it by pressing brieﬂy.

5 To reinstall the communication module, follow

steps 7 to 11 of “Replacing the communication module”, see section above.

▷ The new SIM card requires a new PIN number.

6 Enter the new PIN number via the optical in-

terface. The procedure depends on your user software.

WARNING

Risk of losing data!

– Before changing the SIM card, ensure that the

GSM connection is not active!

Changing the battery

WARNING

▷ The battery can only be replaced when no data

communication is taking place (check for the RF

module symbol in the display). Otherwise, data

communication will be cut off. Replace the battery as shown in the following steps:

0 Reprogram the battery parameters via the optical

interface.

▷ The procedure depends on your user software.

Electrical pulse output

WARNING

Risk of explosion in explosion-hazard areas!

– As a general rule, maintenance and repair work

should be avoided in explosive atmospheres.

– Check that the electrical system complies with

the special electrical explosion protection requirements.

– When working on electrical equipment in an

explosion-hazard area, only design-approved electrical operating equipment may be used.

– This pulse output is not suitable for metrolo-

gical testing purposes, but for monitoring the consumption.

▷ The generated pulses correspond to the values

shown in the technical data, see page 14 (Technical data).

▷

When gas consumption is higher than the output can transmit its pulses, the pulses are buffered and will be transmitted afterwards when con-

sumption is low. Pin assignment: Pin 1, 2, 4, 6: not connected Pin 3: output + Pin 5: output -

▷ To connect the pulse output, use a socket type

IEC 60130-9.

Check test

Directive 2014/32/EU (MID) prescribes that it must be possible to check the meter.

▷

The requirements and test methods must comply

with national laws and regulations.

▷

The following tests describe the check tests

which are carried out by accredited testing

agencies.

▷

Always conduct a pressure and temperature

correction in accordance with established pro-

cedures (unit under test against master meter).

▷

Measurement accuracy class, see page 14

(Technical data).

▷

The unit under test must be acclimatized and

installed on the test rig.

▷

Maintain the climatic conditions constant dur-

ing the entire test duration. Otherwise, the test

results will be inaccurate.

▷ Immediately before commencing the test, pass

the quantity of test air, which corresponds to at

least 50times the cyclic volume of the unit under

test, through the meter at a ﬂow rate of Q

(maximum ﬂow rate of a gas meter).
