▷ The procedure depends on your user software. ▷

For further information, refer to the operating instructions for communication modules type ECM (for electronic index).

Changing the battery

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).

▷ The battery is available as a spare part.

 Prepare the index for changing the battery.

▷

The battery can only be replaced when the optical

communications link has been established, see page 7 (Establishing an optical communica-

GB-7

tions link). Otherwise, data can be lost.

 Start the battery change procedure.

▷ The procedure depends on your user software. ▷

Important! The battery may only be removed once a release message has been issued by the index. Otherwise, an integrated valve will be closed and/or an error message will be transferred via the communication module.

▷ The index conﬁrms disconnection of the battery

with a sound sequence.

 Replace the battery as quickly as possible.

Setting the index parameters

The following index parameters can be adjusted using

Releasing the valve

▷

If a valve is integrated in the diaphragm gas meter BK, this must be released/opened for commissioning.

CAUTION

To avoid damage: – Ensure the customer’s consumers are closed.

▷ The valve can only be released when the optical

communications link has been established or via a communication module.

▷ Unless otherwise agreed, the valve is open on

delivery as standard.

▷ Once the valve has been released via the com-

munication module, this must be conﬁrmed at the meter on site by the consumer or another person if applicable.

 Establish the optical communications link, see

page 7 (Establishing an optical communications link).

The procedure differs depending on whether

the communication module is to be retroﬁtted or replaced. See “Retroﬁtting the communication module” or “Replacing the communication module”.

Retroﬁtting the communication module

▷

Check the status of the interface and deactivate if necessary.

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.

Maintain the climatic conditions constant during the entire test duration. Otherwise, the test results will be inaccurate.

▷

Immediately before the beginning of the test, the quantity of test air, which corresponds to at least 50x the cyclic volume of the meter to be tested, is fed through the meter at a ﬂow rate of Q (maximum ﬂow rate of a gas meter).

▷

During an active cyclic test, the display disappears after 5 minutes but lights up every minute for 10 seconds. This function is available for max. 5 hours.

▷

To conduct the tests, the thermowell and the

pressure test point (if available) can be used as a reference for the temperature and pressure measured by the meter.

Cyclic test

The cyclic test is designed for checking the meter

with a master meter. The recorded volume of the unit under test during the testing period can be read off directly from the index once the test has been completed and can be compared with the master meter. Testing at a constant ﬂow rate thus ensures the lowest possible level of measurement uncertainty for the unit under test.
