Retrofitting/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 re-
quirements.
– When working on electrical equipment in an
explosion-hazard area, only design-approved
electrical operating equipment may be used.
– The communication module may only be pulled
out if it has first been deactivated.
– When installing a communication module, en-
sure that the communication interface has been
deactivated.
– Further information can be found in the operat-
ing instructions for communication modules
type ECM (for electronic index).
– Use original spare parts supplied by Elster
GmbH, see page 14 (Spare parts).
▷
The communication module is available as a
spare part.
▷
The communication module can only be retrofit-
ted or replaced when the optical communica-
tions link has been established.
▷
The procedure differs depending on whether
the communication module is to be retrofitted
or replaced. See “Retrofitting the communica-
tion module” or “Replacing the communication
module”.
Retrofitting the communication module
▷
Check the status of the interface and deactivate
if necessary.

Establish the optical communications link, see
page 7 (Establishing an optical communica-
tions link).
▷
The intended interface for the optional commu-
nication module is UMI-1.
5
The communication module and index must be
paired.
▷
The procedure depends on your user software.
▷
Set the parameters of the communication mod-
ule according to the instructions or the servicing
steps provided by the relevant operator.
6
Replace the service cover.
7
Push in a new screw locking cap, see page 14
(Spare parts). The body carrying out this task
should apply its own seal.
Replacing the communication module
Establish the optical communications link, see
page 7 (Establishing an optical communica-
tions link).
Deactivate the respective communication mod-
ule.

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 15
(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 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
max
(maximum flow rate of a gas meter).
▷
During an active cyclic test, the display dis-
appears after 5 minutes but lights up every min-
ute for 10 seconds. This function is available for
max. 5 hours.
